Automation mechanisms for the pump are used to ensure autonomous operation of devices with the setting of a suitable mode. In addition, high-quality automation protects pumps from dry running and saves energy consumption. This approach allows you to extend the life of expensive pumping equipment.

A special feature of automation from the Gilex company is the ability to use devices both with branded models and with devices from other manufacturers. In addition, inexpensive equipment has a number of other useful properties.

1 Features of the control unit

The main element of automation of the company's pumping process is the Gilex automation unit. Such a device is connected directly to the pumping apparatus and responds to the pressure level in the system.

The Gilex block consists of a plastic case with a metal lid. Inside the housing there is a spring, an electronic unit equipped with a pressure switch and a movable mechanism that closes the contacts when the pressure decreases. For external monitoring of the operation of the device, a pressure gauge is built into the side surface of the block.

The device is designed to operate on the basis of a pumping station or other surface pump pumping clean water. Use with a low content of abrasive impurities is also possible, but in this case the device is equipped with an additional filter.

1.1 Operating principle of the device

Gileks automation operates independently from conventional electrical network. After 30 seconds have passed after installing and connecting the unit, it turns on and works within a few seconds. Then the device turns off and is activated only if the pressure in the line changes.

When the tap at the point of water consumption opens, the pressure in the pipe begins to decrease rapidly. In this case, the unit immediately turns on and, when the minimum pressure is reached, activates the electric pump. The device pumps water until the pressure equalizes again (when the tap closes). After the tap is turned off, the device operates for another 5-20 seconds, continuing to pump water into the line. This measure is a precaution in case the pressure in the system drops below normal and the device is not able to monitor the pressure level.

1.2 HOW IS THE JELEX AUTOMATION UNIT SETUP? (VIDEO)

2 Correct installation of the device

Automation Gilex 9001 is installed in the supply line complete with additional equipment. Therefore, an important step is the correct installation and configuration of all components. Installation of the automatic press control unit from Gilex is carried out in the following order:

First of all, if you purchased a modification without measuring instruments, you should purchase a pressure gauge and install it on sidebar. The mechanism is necessary to monitor and control the unit.
The automatic device itself crashes into the water main in the area between the point of water consumption (tap) and the pumping device. The unit is installed exclusively in a vertical position, with the blue metal cover facing up. In this case, the inlet of the device (indicated in the instructions) should be located on the outlet side of the pump. The outlet conducts the water further into the supply line.
After the control device is installed in the line, it is necessary to carefully inspect all joints and connections for leaks. If errors are found during installation, they should be sealed with sealant or connecting elements.
The unit is connected to the network strictly according to the diagram specified in the instructions. Moreover, if the device is equipped with a pump with a current of more than 10 amperes, a magnetic starter is additionally installed. The main requirement for the electrical cable used with the device is increased resistance to high temperatures.

If necessary, the supply line is supplemented with filters for water purification and a receiver to equalize the pressure in the system.

After all components are installed in the main line, it is necessary to check the device. To do this, the pump inlet is filled with liquid through the pipeline and the pump is turned on. One of the indicators on the unit immediately lights up. This indicates that there is contact between the block and the pumping apparatus. The device works for several tens of seconds and then turns off.

After the device is turned off, you need to open one of the taps (if there are multi-level taps, then preferably the top one). There are two options:

In the first case, water will flow from the tap in a continuous, uninterrupted flow. The unit turns on and the pumping device operates throughout the entire period of use of the tap. In this case, the device was installed correctly.
If the water flow is not stable or absent at all, you can try to restart the device using the “Restart” button. The button is pressed and held until the pumping device operates. If in this case nothing has changed, a thorough inspection of the device and the entire line is carried out, and, if necessary, dismantling and adjustment.

3 Pumping units compatible with the unit

Automation from Gilex is a universal device. With its help, the operation of pumping devices from various manufacturers can be regulated. Regarding the principle of operation, such a mechanism for equalizing pressure is installed on a vibration, centrifugal, vortex, or screw pump.

The device works most efficiently when combined with pumping devices that meet the following characteristics:

current strength in the range of 6-10 A;
device productivity up to 100 l/min;
voltage not higher than 250 V;
the maximum temperature limit of the pumped liquid is 75 degrees;
connection to a pipe with a cross-section of 1 inch.

4 What other automation options does Gilex have?

In addition to the automation unit, the company also produces less popular automation options for pumping equipment. One such option is the installation of Gilex Crab. The device is responsible for stable pressure in the supply line and starts and turns off the pump if necessary. In addition, the filter element cleans the flow of solids.

Gilex Crab consists of the following components:

polymer hydraulic valve;
receiver tank with a volume of 24 or 50 liters, coated with anti-corrosion enamel;
electric pressure switch;
a filter with a replaceable cartridge responsible for cleaning the water stream from impurities;
pressure gauge;
two electrical cables;
special bracket for fixing the unit to the wall.

The device operates on the basis of a standard 220 V electrical network. Suitable for simultaneous connection of 2-3 water intake points. An adjustable relay allows you to set the pressure level that the device will maintain before starting work. Like the previous type of device, Krab 50 is a universal device and is suitable for connecting to borehole pumps any manufacturer.

4.1 Pressure switch RDM-5

More simple option automation of the pumping station is the installation of a special relay RDM-5 on it. The compact device is mounted in the main line and connected to the pumping apparatus using electric cable. The wire is fixed to the relay contacts.

The operating principle of the device is as follows. The device responds to the pressure level in the line. If the indicator is below the set value, the contacts are connected, current is supplied to the water intake point and the liquid fills the pipeline until the pressure returns to normal. When the pressure level returns to normal (this indicator is also set by the user), the contacts diverge. The power supply to the downhole apparatus is interrupted and it turns off.

The minimum and maximum values at which the pumping device is activated are set by the user. They can be adjusted using two nuts that fix the degree of spring tension. The larger nut, when rotated counterclockwise, sets the maximum pressure reading; the smaller nut, when rotated, allows you to adjust the difference between the maximum and minimum readings.

RDM-5 is designed for use exclusively in water. The operating voltage for the device is 220-230 V. The temperature of the pumped liquid is 0-40 degrees. The relay is fixed to a ¼-inch pipeline. A prerequisite for using RDM-5 is high-quality grounding.

4.2 Float switch

For drainage, fecal and surface pumps for water the cheapest and in a practical way automation is a float switch. According to the scope of use, such devices are divided into light and heavy. Light floats are equipped with drainage models, heavy floats are installed at water supply stations and water pumps.

The design consists of an electric cable 3,5,8 or 10 m long and a plastic float mechanism. Inside the float there are two contacts, a switch lever and a ball that changes the position of the lever. Based on the number of wires, two and three-wire floats are distinguished.

In the version with two wires, they are directly connected to the float contacts. When such a mechanism rises with the water level to the designated level, the lever presses on the contacts, they close and supply energy to the pump.

Models with three wires support the ability to turn on the pick-up point in the extreme upper and extreme lower positions. To do this, one wire goes to one of the contacts, and the other two wires, depending on the position, go to the second contact.

The principle of operation of such a float mechanism is that the device automatically turns on the pump when the water level rises to the set value. In the case of a two-wire device, the float, on the contrary, opens the contacts and turns off the device when the water drops below normal.

Gilex automation is multifunctional, easy to use and install, and affordable. It can work with both native pumps and pumps from other manufacturers to automate water supply.

The company offers reliable and modern options automatic pumps with long term operation and good characteristics. Let's take a closer look.

Total pump automation

We start the automation as follows:

Immediately before turning on the device, completely fill the inlet pipe of the pump with water and start it (the “Network” LED should light up). This manipulation will turn on the automation unit. As soon as the pump starts working and stops after a while, you need to open the outlet valve, which is located at the highest point.
If the pump runs all the time with the tap open and provides a continuous flow of water, the installation is considered correct. The absence of water flow indicates that you need to hold down the “Restart” button and hold it for the duration of the response time automatic system. If after such manipulation the flow is still missing, you need to repeat the launch.

Idling protection

When the “Protection” LED on the automation unit lights up and the pump itself is turned off, this may indicate a danger of idle operation of the system. This is how press control works.

Recheck all systems. If everything is in order, drain the water from the incoming system and refill it. Then click the “Reboot” button.

Optimal automation characteristics for pumps

A vibration or any other type of pump can be additionally equipped with automation systems. But, they have different parameters, properties, etc. Which ones are worth purchasing?

Technical indicators (optimal):

Operating voltage = 210-250 V;
Frequency = 40/70 Hz;
Minimum operating pressure = 1-4 atm.;
Load current = 6-10 A;
Water flow speed = 70-100 l/min;
Upper pressure threshold = 15 atm;
Limit water temperature = 75 degrees;
Inlet pipe diameter = 1 inch;
Degree of protection = 1P65.

What do you need to know?

Important! The valve located on the section of pipe between the automatic/pumping systems and the valve running on the outlet pipe of the automatic unit are the culprits of equipment malfunctions.

The minimum operating pressure of the equipment cannot be changed independently. This should be done by electricians who have experience and are familiar with regulatory documentation and comply with safety standards.

The maximum operating pressure is not automatically regulated. It corresponds to the indicator of an electric pump.

1 Features of the company's control unit

1.1 Operating principle of the device

Gileks automation operates autonomously from the regular electrical network. After 30 seconds have passed after installing and connecting the unit, it turns on and works within a few seconds. Then the device turns off and is activated only if the pressure in the line changes.

Design and principle of operation of a water pressure switch

Structurally, the relay is made in the form of a compact block with springs of maximum and minimum pressure, the tension of which is regulated by nuts. The membrane connected to the springs reacts to changes in pressure force. When the minimum value is reached, the spring weakens; when the maximum level is reached, it compresses more strongly. The force exerted on the springs causes the relay contacts to open (close), turning the pump off or on.

The presence of a relay in the water supply allows the system to provide constant pressure and the required water pressure. The pump is controlled automatically. Correctly set levels of minimum and maximum pressure ensure its periodic shutdown, which contributes to a significant increase in trouble-free service life.

The operating sequence of the pumping station under relay control is as follows:

The pump pumps water into the tank.
The water pressure is constantly increasing, which can be monitored by the pressure gauge.
When the set maximum pressure level is reached, the relay is activated and turns off the pump.
As the water pumped into the tank is consumed, the pressure decreases. When it reaches the lower level, the pump will turn on again and the cycle will repeat.

Basic parameters of relay operation:

Lower pressure (switch-on level). The relay contacts that turn on the pump close and water flows into the tank.
Upper pressure (shutdown level). The relay contacts open and the pump turns off.
Pressure range is the difference between the two previous indicators.
The value of the maximum permissible shutdown pressure.

Setting up the pressure switch

During the assembly of the pumping station Special attention is paid to setting up the pressure switch. The ease of operation of the water supply system, as well as the trouble-free service life of all components of the device, depend on how correctly its limit levels are set.

At the first stage, you need to check the pressure that was created in the tank during the manufacture of the pumping station. Typically, at the factory, the switch-on level is set at 1.5 atmospheres, and the switch-off level is 2.5 atmospheres. They check this with an empty tank and the pumping station disconnected from the power supply. It is recommended to check with an automotive mechanical pressure gauge. It is housed in a metal case, so the measurements are more accurate than using electronic or plastic pressure gauges. Their readings can be affected by both the room temperature and the battery charge level. It is desirable that the pressure gauge scale limit be as small as possible. Because on a scale of, for example, 50 atmospheres, it will be very difficult to accurately measure one atmosphere.

To check the pressure in the tank, you need to unscrew the cap that closes the spool, connect the pressure gauge and take a reading on its scale. The air pressure should continue to be checked periodically, for example once a month. In this case, the water must be completely removed from the tank by turning off the pump and opening all taps.

Another option is to carefully monitor the pump shut-off pressure. If it increases, this will mean a decrease in air pressure in the tank. The lower the air pressure, the greater the supply of water can be created. However, the pressure spread from a completely filled to an almost empty tank is large, and all this will depend on the preferences of the consumer.

Having chosen the desired operating mode, you need to set it by bleeding off excess air, or pump it up additionally. It must be borne in mind that the pressure should not be reduced to less than one atmosphere, nor should it be over-pumped. Due to the small amount of air, the rubber container filled with water inside the tank will touch its walls and be wiped. And excess air will not make it possible to pump in a lot of water, since a significant part of the volume of the tank will be occupied by air.

Setting the pump on and off pressure levels

In pumping stations that are supplied assembled, the pressure switch is pre-configured according to the optimal option. But when installing it from various elements The relay must be configured at the site of operation. This is due to the need to ensure an effective relationship between the relay settings and the tank volume and pump pressure. In addition, it may be necessary to change the initial setting of the pressure switch. The procedure should be as follows:

In practice, the pump power is selected such that it does not allow the tank to be pumped to the extreme limit. Typically, the cut-out pressure is set a couple of atmospheres above the switch-on threshold.

It is also possible to set pressure limits that differ from the recommended values. In this way, you can set your own version of the operating mode of the pumping station. Moreover, when setting the pressure difference with a small nut, one must proceed from the fact that the initial reference point should be the lower level set by the large nut. The upper level can only be set within the limits for which the system is designed. In addition, rubber hoses and other plumbing fixtures also withstand pressure, not higher than the calculated one. All this must be taken into account when installing a pumping station. In addition, excessive water pressure from the tap is often completely unnecessary and uncomfortable.

Return to content

Adjusting the pressure switch

Adjusting the pressure switch is practiced in cases where it is necessary to set the upper and lower pressure levels to the specified values. For example, you need to set the upper pressure to 3 atmospheres, the lower pressure to 1.7 atmospheres. The adjustment process is as follows:

Turn on the pump and pump water into the tank until the pressure on the pressure gauge reaches 3 atmospheres.
Turn off the pump.
Open the relay cover and slowly turn the small nut until the relay operates. Rotating the nut clockwise means increasing pressure, in the opposite direction means decreasing. The upper level is set to 3 atmospheres.
Open the tap and drain the water from the tank until the pressure on the pressure gauge reaches 1.7 atmospheres.
Close the tap.
Open the relay cover and slowly rotate the large nut until the contacts operate. The lower level is set at 1.7 atmospheres. It should be slightly greater than the air pressure in the tank.

If asked high pressure to turn off and low to turn on, the tank is filled with a large amount of water, and there is no need to turn on the pump often. Inconveniences arise only due to the large pressure drop when the tank is full or almost empty. In other cases, when the pressure range is small and the pump often has to be pumped up, the water pressure in the system is uniform and quite comfortable.

In the next article you will learn about connecting a hydraulic accumulator to a water supply system - the most common connection diagrams.

How does the pressure switch on a hydraulic accumulator work?

The hydraulic accumulator, together with the pressure switch and pump, are the most important parts of the water supply for a summer house, farm and other buildings. A correctly configured and installed sensor can relieve the owner of most water-related problems.

Connecting a pressure switch and installing additional equipment is not an easy process; it requires attention and specific knowledge of electronics and the operation of a pumping station with a hydraulic accumulator.

1 Description of the sensor and pumping system

Water pressure sensor – electrical appliance, providing pressure regulation in the hydraulic accumulator for the pumping station. It also monitors the liquid pressure in the pipeline and turns on or off the water supply to the accumulator tank.

This happens due to the short circuit of the wires. Exceeding the permissible threshold opens the contacts and the relay turns off the pump. A drop below the set level closes the contact of the device, turning on the water supply. You can manually adjust both the upper and lower thresholds.

Pressure switch operation diagram

Basic concepts of a pressure switch for a system with a hydraulic accumulator:

Rvkl – lower pressure threshold, power on, in standard settings it is 1.5 bar. The contacts are connected, and the pump connected to the relay begins to pump water;
Roff – upper pressure threshold, switches off the relay power, it is better to set it to 2.5-3 bar. The circuit is disconnected and an automatic signal stops the pumps;
delta P (DR) – indicator of the pressure difference between the lower and upper thresholds;
maximum pressure – as a rule, does not exceed 5 bar. This value is displayed in the characteristics of the control device for water supply systems and does not change. Exceeding leads to equipment breakdown or reduction of the warranty period.

The main element of the pressure switch for the hydraulic accumulator is a membrane that responds to water pressure. It bends depending on the pressure and tells the mechanism how much the water pressure in the pumping station rises or falls. The bend switches the contacts inside the relay. A special spring (which is tightened for adjustment) counteracts the pressure of water. The smaller spring determines the differential, that is, the difference between the lower and upper pressure thresholds.

Relays can be of two types. The first, power, directly acts on the pump contacts. The control type interacts with the station automation and through it affects the operation of the pump.

The hydraulic accumulator and pressure switch form reliable system to ensure water supply to any premises, outbuildings, fields and others. Automation for the pump is also a necessary part - thanks to it, it becomes as easy as possible to control the collection of water and quickly pump liquid into the tank and into the pipes.

Pumping station pressure switch device

You can always connect an additional hydraulic accumulator, as well as relays, automation, sensors and pumps.

1.1 Adjusting the pressure switch for the hydraulic accumulator

Before connecting the equipment to the tank, you should check the functionality of the relay and adjust it. It is recommended to take readings with a mechanical pressure gauge. It is more accurate and less susceptible to internal failures, which may cause its readings to be inconsistent.

Next will be instructions on how to properly configure the pressure switch. First of all, you need to familiarize yourself with the passport of the device, pump and accumulator tank in order to find out the pressure limits for these elements of the pumping station. It makes the most sense when purchasing familiarize yourself with these parameters in advance and adjust them to each other.

Open the water supply (tap, hose, valve) so that, thanks to the pressure gauge, you can see the pressure at which the relay is activated and the pump is turned on. Usually this is 1.5-1 bar.
Water consumption is turned off to increase the pressure in the system (in the accumulator tank). The pressure gauge records the limit at which the relay turns off the pump. Usually it is 2.5-3 bars.
Adjust the nut attached to the large spring. It determines the value at which the pump turns on. To increase the switching threshold, tighten the nut clockwise; to decrease it, loosen it (counterclockwise). Repeat the previous steps until the switching pressure does not correspond to the desired one.
The shutdown sensor is adjusted using a nut on a small spring. It is responsible for the difference between the two thresholds and the setting principle is the same: to increase the difference (and increase the shutdown pressure), tighten the nut; to decrease it, loosen it.
It is not recommended to turn the nut more than 360 degrees at a time, as they are very sensitive.

1.2 How to set up a pressure switch at a pumping station? (video)

2 Pump with hydraulic accumulator

Since the sensor also determines the air pressure in the hydraulic accumulator of the pumping station, you should also know the description of this equipment. This will ensure proper connection of the hydraulic accumulator. If you seriously think about how to choose a hydraulic accumulator, then you should pay attention to the following items.

The device is a metal tank with a capacity of 19, 24, 50 liters or more, up to 1000. Tanks of 50 and 24 liters are the most common for summer cottages and small country houses. However Please note that the total volume of the tank is not the volume of water. which it may contain. Inside the accumulator tank, the air pressure should be approximately 0.2-0.3 bar less than in the pipeline.

The choice must be made taking into account the pressure settings; the higher the settings and the more durable the device, the more water can be loaded into the tank. So in a pumping station with a 24-liter tank, with a pressure Poff equal to 2.5 and Poff equal to 1.0, the volume of stored water will be a little over 9 liters. Special tables will allow you to correctly select the volume of the tank and the power of the pressure switch. Which one is better depends on the depth of the well, the length of the pipeline and the frequency and purpose of use.

Pumping stations with hydraulic accumulators come in bulb and membrane types. The first type has an internal rubber container, a “bulb,” into which air is pumped by a pump. The bulb expands and presses on the water inside the tank, ensuring its flow through the pipes. How to pump air into the “pear”?

Pump with hydraulic accumulator

To do this, use the usual air pump and car nipple. The membrane structure is a little different: water is pumped into a rubber container (made of butyl), and air is pressed with outside containers. The air is located between the metal walls of the tank and the membrane with water.

The hydraulic accumulator is connected to the submersible pump through a system consisting of the following elements:

pressure switch;
dry running sensor;
pipeline circuit;
water purification filters;
automation unit and additional equipment.

2.1 Checking the accumulator pressure

Before connecting to the network and pumping system, the accumulator must be pressure tested. Since the principle of operation of the pumping station is to pump pressure into the pipes using relays, pumps and a hydraulic accumulator, checking is an extremely important operation. Monitoring the level of air pressure, which will change over time due to wear, breakdowns, and clogging, is the most difficult part of preventing a pumping station.

Indicators are taken with a pressure gauge. You need to remove the decorative cap and connect the pressure gauge to the nipple of the accumulator tank. A figure of 1.5 bar is usually considered acceptable. however, less will do – up to 0.8, depending on the type of tank. This is how the hydraulic accumulator for the pumping station is configured.

Tool kit for connecting a hydraulic accumulator

Adjusting the air pressure inside the tank will allow you to change the water pressure. The higher the water pressure, the faster the system wears out. Low water pressure will not allow you to use a hydromassage shower or Jacuzzi, but will significantly save money on repairs and replacement of parts of the hydraulic pump system.

2.2 How to connect a hydraulic accumulator to a relay?

The relay is connected to the electrical network with two pairs of contacts. The connection to the pipeline is made using a threaded hole, the standard diameter of which is 0.25 inches (6 millimeters). In order to independently provide pumping station pressure switch, the following tools are required:

coupling with a union nut (popularly “American”), as a rule, a diameter of 1” is used;
coupling with collet clamp;
MPH coupling;
brass adapter;
hermetic sealing tape (preferably FUM, it ensures a stable connection of the pump to the hydraulic accumulator);
pipes, fittings, pressure switch, hydraulic accumulator.

Connection diagram of the hydraulic accumulator to the water supply system

The diagram for connecting a hydraulic accumulator to a pumping station with your own hands is as follows:

The threads of the hydraulic accumulator tank must be sealed with tape to avoid water leaks, air penetration into the system, to facilitate maintenance, as well as to make subsequent repairs and replacement of pipes easier.
The pressure switch is not connected directly, but using a coupling with a union nut. This is also done to simplify further repairs of equipment and more tightly insulate the pipeline. This coupling also facilitates both connection and subsequent adjustment of the automation.
The relay is connected at the required angle so that when the equipment is installed, you can easily monitor the indicators. Here they take into account that sometimes all automation is placed in hard-to-reach places - in narrow nooks and crannies, small technical rooms, even lowered inside a closed well or borehole. Therefore it is very important to determine required angle tilt the relay and possibly connect it to other works, and not directly to the tank.
Just in case, the pressure gauge can also be covered with sealing tape, although a gasket is used there.
It is necessary to solder an elbow from plastic pipe fittings for the consumer line.
The regulator is connected to the elbow thanks to the MPH coupling soldered to the pipe and using a brass adapter.
For deep, submersible pumps, polyethylene pipes are often used. To tightly connect them to the relay, a coupling with a collet clamp is required.
The preparatory part is completed and then it is necessary to connect the accumulator and pressure switch with the rest of the pumping station.
After connecting to the pipeline, you need to connect the electricity.
The regulator cover fastening is unscrewed with a regular screwdriver. Inside there are inlet holes to which power wires are supplied. and pump cable. The contacts are signed or they are indicated in the instructions.

In this way, the pressure switch and hydraulic accumulator are connected to the pumping station.

Setting the pressure switch and adjusting the air pressure in the accumulator.

Pressure switch- an element that controls the operation of a pumping station (for example AQUAJET or AQUAJET-INOX) and which makes it possible to operate it in automatic mode. The pressure switch has several characteristics:

Switch-on pressure (P on) is the pressure (bar) at which the pumping station is turned on by closing the contacts in the pressure switch. Sometimes the switching pressure is also called “lower” pressure.
Shutdown pressure (P off) is the pressure (bar) at which the pumping station is turned off by opening the contacts in the pressure switch. Sometimes the shutdown pressure is also called “upper” pressure.
Pressure drop (ΔP) is the absolute difference between the switch-off pressure and switch-on pressure (bar).
Maximum cut-out pressure- this is the maximum pressure (bar) at which the pumping station can be turned off.

Any pressure switch has factory settings and, as a rule, they are as follows:
Switching pressure: 1.5-1.8 bar
Shutdown pressure: 2.5-3 bar
Maximum cut-out pressure: 5 bar

How it all works:
Let’s say the pumping station is connected (more on this in the article “Preparing the DAB pumping station for operation”), and the entire system is filled with water. After opening any tap (shower, sink, etc.) and starting to draw water, the pressure in the system will begin to drop smoothly (thanks to the membrane hydraulic tank), which is easy to track with a pressure gauge. All this time, water is supplied to the consumer from the hydraulic tank. When the “lower” switching pressure is reached (it can also be monitored by a pressure gauge at the moment the pump is switched on), the contacts inside the pressure switch will close and the pump will start. The rest of the time of water collection, the pump continues to operate, supplying water directly to the consumer. After the water withdrawal is completed (all taps are closed), the pump still continues to work, only now the water is not supplied to the consumer, but is pumped into the hydraulic tank (since it has nowhere else to go) and the pressure gradually increases. When the shutdown pressure is reached (can be easily monitored on the pressure gauge when the pump stops), the contacts inside the pressure switch open and the pump stops. At the next water draw, the cycle repeats. It's quite simple.

But what to do if the factory settings of the pressure switch are not very comfortable? For example:on the upper floors the pressure drops very noticeably, or the water purification system requires at least 2.5 bar at the inlet, while the pump turns on only at 1.5-1.8 bar.

You can set the pressure switch yourself:

Using a pressure gauge, we record the on and off pressure when the pump is running. Turn off the power to the pump and remove the top cover of the pressure switch (usually by unscrewing one screw). You will see two screws, one larger one is located on the top of the relay, and the second, slightly smaller one, is located below it. The top screw is responsible for the shutdown pressure and, as a rule, next to it there is the letter “P” and an arrow with the signs “+” and “-”. Then we rotate the screw in the desired direction (if the shutdown pressure needs to be raised, then rotate in the direction of the “+” sign, if lowered, then in the direction of the “-” sign). How much to rotate? Make a turn (half a turn, one and a half - as much as you want). After this, we start the pump and see at what pressure it turns off now. We remember, turn off the power to the pump, and rotate the screw further, start the pump again and write down the new value, thus getting closer to the desired value.

The lower screw is responsible for the difference between the cut-off pressure and the cut-in pressure. As a rule, “ΔP” is written next to it and there is an arrow with “+” and “-” signs. Setting the pressure difference is similar to setting the cut-off pressure. There is only one question left: what should it be? The difference between switch-on and switch-off pressure is usually 1.0-1.5 bar. Moreover, the higher the shutdown pressure, the greater this difference can be. For example, with factory settings P on = 1.6 bar, P off = 2.6 bar, the difference is 1 bar, this is exactly the standard value. If we want to change the factory settings and raise P off to 4 bar, then the difference can be made by 1.5 bar, i.e. P on should be set at 2.5 bar. You must understand that the greater this difference, the higher the pressure drop in the system, which is not always comfortable. But at the same time, the pump will turn on less often, and more water will flow from the hydraulic tank before the pump turns on.

This is only true if the pump can provide the required pressure (see pump characteristics). Those. if the pump can only produce 3.5 bar according to its passport (taking into account all types of losses), then setting the pressure switch to turn off 4 bar will not do anything. The pump simply will not be able to provide the required pressure and in this case will work without stopping. And if you still need exactly 4 bar, then you will have to change the pump to a more powerful one.

What should the air pressure be in the air cavity of the hydraulic tank?

Many people don’t think about it, or simply don’t know that they need to keep an eye on this. Unfortunately, yes, it is necessary; the service life of the hydraulic tank membrane, and ultimately the pump, directly depends on this.

We measure the air pressure in the air cavity of the hydraulic tank. Let's do it only with the hydraulic tank disconnected from the system— turn off the power to the pump, open any tap behind the pump and wait until the water comes out of the hydraulic tank. Or we measure it on an installation that is not yet connected to the water supply system. To do this, remove the decorative cap from the air nipple of the hydraulic tank and connect a regular car pressure gauge to it (to check the pressure in the car tires). Let's remember this pressure. (As a rule, on small hydraulic tanks with a capacity of up to 50 liters, this pressure will be 1.5 bar). Now the most important rule : the air pressure in the hydraulic tank should be approximately 10% less than the pump activation pressure. Those. if the pump activation pressure is 1.6 bar, then the air pressure should be 1.4-1.5 bar. In most cases, these are the factory settings mentioned above. Those. By purchasing a ready-made pumping station, you already have a fully configured system. But once you have made changes to the factory settings of the pressure switch, you must always change the air pressure in the hydraulic tank. For example, if you set P on = 2.5 bar, P off = 3.5 bar, then it is necessary to raise the air pressure to a value of 2.2-2.3 bar.

By the way, even if you haven’t changed anything in the factory settings, you need to regularly monitor the air pressure, or at least check it once a year at the beginning summer season. It is important that this pressure be constant, but if it has dropped a little over the winter, it can always be raised with a regular car pump to the required level.

All these simple operations will not take much time; it is enough to pay attention to them once a year, especially since everything will pay off in the long and uninterrupted operation of the entire water supply system as a whole.

Pressure switch for hydraulic accumulator: information on installation and configuration

When providing a building with water from a well or well in mandatory a hydraulic accumulator is installed, which is a container of suitable volume. It is usually used in conjunction with a special pressure switch. For the hydraulic accumulator, it is a control device that allows you to reduce the number of pump operating cycles.

Main components pumping unit with hydraulic accumulator

Working elements of the device and operation

From point of view design features the relay is a small unit equipped with special springs. The first of them determines the limit of maximum pressure, and the second - the minimum. The adjustment is made using auxiliary nuts located inside the housing.

Familiarization with internal structure devices

The working springs are connected to a membrane, which reacts to pressure surges in one way or another. Exceeding the maximum values leads to compression of the metal spiral, and a decrease leads to stretching. Thanks to this device, the contact group closes and opens contacts at a certain moment.

Location of the device in the general diagram

The operating principle of a pressure switch for a hydraulic accumulator is as follows. Water enters the membrane tank until it is completely filled, which leads to an increase in pressure. With achieving the maximum permissible level the pump stops pumping liquid.

As water is consumed, the pressure in the system drops. When the lower level is overcome, the equipment will turn on again. Cycles of on and off are repeated over and over again until the system elements are in working order.

Connection diagram if there is a drain valve in the system

Typically a relay consists of the following elements:

plastic housings;
rubber membrane;
brass pistons;
membrane cover;
threaded studs;
metal plate;
couplings for cable fastening;
terminal blocks;
articulated platform;
adjusting springs;
contact node.

Using a pressure gauge, you can visually determine the pressure

Addition! During operation, adjustment springs apply pressure to the moving part of the platform, counteracting the force created by the piston. Turning the pump on and off depends on the degree of compression.

Optimal pressure inside the hydraulic tank

Any hydraulic accumulator inside has a rubber membrane that divides the space into two chambers. One of them contains water, and the other contains compressed air. Thanks to this structure, it is possible to create the necessary pressure when filling and emptying the rubber container.

The structure of the hydraulic accumulator is clearly shown

To extend the life of the device, you need to know what pressure should be in the accumulator. It largely depends on the indicators set to turn on the pump. The pressure inside the tank should be approximately 10 percent less.

Checking the tank pressure

For example, if the turn-on is set to 2.5 bar and the turn-off is set to 3.5 bar, then the air pressure inside the container should be set to 2.3 bar. Ready-made pumping stations usually do not require additional adjustment.

Carrying out work on connecting and setting up a pressure switch for a hydraulic accumulator

Although many people consider the process of installing and adjusting the device to be difficult to understand, in fact it is not. Each owner of a country house with a well or well can independently connect and configure the device to provide the building with water.

One of the diagrams for connecting a hydraulic accumulator to the system

Standard diagram for connecting a pressure switch to a hydraulic accumulator

The finished product interacts with both water supply and electrical system building. When the contacts are closed and opened, liquid is supplied or shut off. The pressure device is installed permanently, since there is no need to move it from place to place.

The purpose of the contact groups of the device is indicated

It is recommended to allocate a separate electricity line for connection. Directly from the shield you should run a cable with a copper core with a cross-section of 2.5 square meters. mm. It is not recommended to connect wires without grounding, because the combination of water and electricity is fraught with hidden danger.

A visual diagram for connecting a relay yourself

The cables should be passed through the holes located on the plastic case, then connect to the terminal block. It contains terminals for phase and neutral, grounding. wires for the pump.

Note! Electrical installation work must be carried out disconnected from the network. When installing, you must not neglect compliance general rules technical safety.

Correct setting of the accumulator pressure switch

To adjust the device, an accurate pressure gauge is required to determine the pressure without errors. Based on its readings, you can make a relatively quick adjustment. By turning the nuts located on the springs, the pressure can be reduced or increased. During setup, you must follow a certain sequence of actions.

Work is underway to configure the device

So, the pressure switch for the hydraulic accumulator is adjusted as follows.

The system turns on, after which, using a pressure gauge, the indicators at which the device turns on and off are monitored;
First, the lower level spring is adjusted, having big sizes. For adjustment, use a regular wrench.
The set threshold is tested. If necessary, the previous point is repeated.
Next, the nut for the spring is rotated, allowing you to set the upper pressure level. It is smaller in size.
The system is fully tested. If for some reason the results are not satisfactory, then re-tuning is performed.

The adjusting nuts of the device are demonstrated

Note! Before setting up the accumulator pressure switch, you need to remember a simple truth. The minimum permissible difference between the maximum and minimum values should not be less than 1 atmosphere.

Cost of relays and hydraulic accumulators of some manufacturers

Relay models can be purchased relatively inexpensively. Usually the cost of products does not exceed one thousand rubles. However, electronic analogues may have a higher price, as they allow for more precise adjustments. The table shows models of some manufacturers and their prices.

Pressure switch Gilex RDM-5 presented

Note! On average, a hydraulic accumulator with a capacity of 50 liters is usually enough for a family of 4-8 people. If there are fewer people living, a capacity of 24 liters is purchased, and if there are more people, 100 liters.

Hydraulic accumulator Gilex, holding 24 l

Summarizing

Since a hydraulic accumulator cannot function without a pressure switch, which is a control device, special attention was paid to the installation and configuration of this particular device. With proper adjustment of the product, it is quite possible to extend the operating period of the main equipment.

We offer for sale modern automation units for pumps manufactured by Gilex. Before you buy automatic device, we suggest you familiarize yourself with its characteristics.

The automation unit (automatic device) allows you to automate the operation of the electric pump, start it when the pressure decreases (when the tap is opened) and stop when the water flow in the water supply system stops (when the tap is closed). In addition, the automation unit protects the pump from running without water (“dry running”).

The automation unit is designed for pumping clean water that does not contain solid particles. If there are solid particles, it is necessary to install a filter at the entrance to the automation unit. The presence of a pressure gauge provides visual control of the pressure in the water supply system.

Operating principle

The automation unit starts the electric pump within 20-25 seconds after connecting to the power supply. Subsequent starts of the electric pump occur when the starting pressure is reached, under the influence of opening the tap. Unlike systems with a pressure switch-tank, the condition for stopping the electric pump is not dictated by the achievement of a certain pressure in the system, but is determined by a decrease in flow to minimum values. As soon as the automation unit detects this condition, it stops the electric pump with a delay of 7+15 seconds, the timing logic is aimed at reducing the frequency of operation of the electric pump in low flow conditions.

The automation unit can be used in conjunction with the RDM-5 pressure switch

Installation

1. The pressure gauge can be mounted on one of the two sides of the automation unit using an O-ring and two mounting screws. By selecting convenient location pressure gauge, plug the hole on the opposite side with a screw without using any seal. Install the automation unit in a strictly vertical position at any point located between the pump supply and the first water intake point (faucet) so that the inlet hole (external thread 1″) is connected to the direction of water flow exiting the pump, and the side outlet hole (external thread 1″) corresponded to the direction of flow in the pipeline. Make sure that the hydraulic connections are completely tight. If you use an electric pump with a maximum pressure of more than 10 bar, it is necessary to install a pressure reducer at the inlet to the automation unit.

2.For electrical connection, follow the diagram on the circuit board cover. When using an automation unit with three-phase or single-phase electric pumps with a switching current of more than 10 A, use an electromagnetic starter. It is necessary to use an electrical cable with a thermal resistance of at least 99° C.

3. The starting response pressure is set to 1.5 atm, which is optimal value for most use cases. This value can be changed using adjusting screw located on the top of the automation unit marked “+” and “-”.

Starting the automation unit

ATTENTION: If the level of water being filled is lower than the level at which the pump is installed, it is imperative to use a bottom check valve on the suction pipe.

1. Before putting it into operation, completely fill the suction pipe and electric pump with water and start the latter, thereby giving power to the “NETWORK” automation unit. After stopping the electric pump, open the tap located at the highest point.

2. The installation is correct if the electric pump operates continuously and there is a regular flow of water at the outlet of the tap. If there is no water flow, you can extend the operation of the electric pump by holding down the “RESET” button for a period exceeding the timing time of the automation unit. If in this case there is no flow, you should turn off the power to the electric pump and repeat the procedure starting from step 1.

Dry code protection

The red “PROTECTION” indicator lights up when the electric pump turns off, signaling the danger of dry running. After making sure that the suction line is filled with water, start the electric pump by pressing the “RESET” button.

Design and principle of operation of automation for the pump

There are various automation equipment for pumps, among which are dry-running blockers, water pressure switches, electronic units, sensors, etc. As a rule, electronics operate in conjunction with additional equipment (hydraulic accumulator, float switch, etc.). In this case, the operation of the pump group can be adjusted both by pressure and by flow. An important component is a pressure gauge, which provides visual control of the parameters of the water supply network.

Today there are several generations of automation for pumps. The latest electronic devices are considered the most efficient due to high-tech equipment, advanced functionality and more sophisticated settings.

General operating principle:

when the pressure drops, the unit independently starts the pumping unit (in particular, this happens when the taps are opened);
if there is no water flow, the electric pump turns off (all taps are closed);
Automatic stopping of the pump group can also occur if the fluid flow is not high enough (protection against “dry running”).

What functions does the device perform?

In private houses where there is no running water supply, the issue of providing drinking water is solved in 2 ways:

installation of a container or construction of a pool filled with imported water;
drilling a well to an aquifer.

Water is supplied to the house using a pump of the required power. But the amount of water pressure during its operation is too high to connect the pumping unit directly to internal water supply networks. Therefore, an intermediate tank with a membrane is installed in the house - a hydraulic accumulator, and required pressure supports RDM 5 pressure switch in the network. The device allows you to automate the process of supplying water to autonomous systems ah water supply.

Operating principle

The device consists of a brass body with fittings for connecting to the water supply network, spring valves and an electric relay. On the outside, the elements are covered with a plastic cover. The operating diagram of the RDM 5 pressure switch is as follows:

The manufacturer sets the device to the lowest pressure limit of 1.4 Bar, the highest - 2.8 Bar. When the pressure in the accumulator is less than the lower limit, the relay contacts are closed and the pump pumps water into the intermediate membrane tank.
When the pressure has risen to the upper limit (2.8 Bar), the spring valve is activated and opens the relay contacts. The water supply stops.
When water supply appears in the house, the hydraulic accumulator begins to empty, the pressure decreases, and when the lower threshold of 1.4 Bar is reached, the relay contacts close again and the pump resumes its operation.

As a rule, the RDM 5 device is equipped with ready-made pumping stations, consisting of a pump, a water accumulator tank and the control relay itself. The station is configured at the factory and is completely ready for operation; all that remains is to connect it to the pipe and the electrical network. But finished products are not suitable for everyone for the following reasons:

the hydraulic accumulator capacity is insufficient;
the pressure of the standard pump is small to ensure the supply of water to required height;
used deep well pump, lowered into the well.

In the above cases, the system automatic feeding water will have to be collected from individual elements, and adjust the pressure switch accordingly, coordinating its operation with the storage tank. Before purchasing and connecting a device, it is recommended to study its technical characteristics:

pressure control range in the water supply system - from 1 to 4.6 bar;
ambient temperature range - from 0 to +40 °C;
minimum pressure drop - 1 bar;
supply voltage - 220 V;
The diameter of the fittings is DN 15, the connection is G ¼’’.

If any of technical characteristics relay RDM 5 is not suitable for you, then you will have to look for another regulator. But practice shows that the parameters of this device meet the requirements of the overwhelming number of autonomous water supply systems.

How to adjust the device?

Setting up the pressure switch is carried out after installing the internal and external water supply network of the house and connecting it to the electrical network.

Connections of external and internal pipelines must be verified by testing so that subsequent leaks do not interfere with the adjustment process. Due to leaky joints, the pressure before or after the pump will spontaneously decrease, which will also affect the operation of the relay.

Before setting, you should determine the required pressure value. To supply water to all water collection points located on different floors, it is necessary to ensure the necessary pressure in the accumulator. The forces of the tank membrane must be sufficient to push the entire volume of water to the required height and overcome all local resistance. At home, this pressure value is most often determined experimentally.

The calculation is simple: 1 m of lift height is equal to 10 m of horizontal section and corresponds to a pressure of 0.1 Bar. The farthest branch of the water supply is taken into account. Having approximately determined the required pressure, it is necessary to create such pressure from the air chamber of the accumulator. To do this, remove the plastic cap from the spool valve (usually located at the end of the reservoir) and pump up the air chamber with a regular car pump, monitoring the pressure with a pressure gauge.

Without connecting the internal water supply pipe, check how the relay works together with the pump at the factory settings. At the same time, check the tightness of the external pipeline.
Remove the plastic relay cover covering the adjustment screws.
The large screw adjusts the upper limit (pump shutdown), the small screw adjusts the pressure drop. Adjust the lower limit so that its value is 0.2 bar more than what you pumped into the accumulator.
To reach the exact values, you will have to adjust it several times, opening the faucet taps and releasing water from the battery. At the same time, record the pressure gauge readings when turning the pump off and on and adjust them with the adjusting screws.

As a result of the settings, the difference between the lower and upper limit should not be less than 1 Bar. Practice shows that the optimal pressure drop is about 1.5 Bar, then the pump will not turn on too often. After completing the adjustment, do not rush to put the cover back in place; monitor the operation of the system for 1 day. Minor adjustments may be needed.

Principle of operation

Despite the fact that the relay regulates the water pressure, its mechanisms include electrical components. Under water pressure, two contacts are closed, this is how the connection to the electrical network is made:

when the pressure is below the set upper pressure limit, the relay contacts remain closed and the pump continues to pump water;
When the pressure exceeds the upper pressure limit, the contacts open and the pump stops working.

The principle of operation is not complicated, but consumers encounter some difficulties when adjusting the pressure switch and setting the lower and upper limits.

Adjustment method

Factory settings of pressure switches by manufacturers are not always accurate or suitable for local operating conditions. But the design is made in such a way that each owner can adjust the necessary parameters without any problems. In private homes, pumps at the water supply point in front of the accumulator must create a pressure pressure of at least 1.4 atmospheres. Otherwise, the adjustment makes no sense, the contacts will not close and the pump will not turn on. There must be a pressure gauge at the connection point; according to its readings, the pressure value is judged:

Connection diagram of the relay to the expansion tank

We connect the pressure switch to the receiving point, as required by the instructions, the hydraulic accumulator is not connected, a plug is installed instead. The pump is connected to the network - this way the operation of the relay at factory settings and the tightness of the network to the relay are checked.
Record the pressure gauge readings (3 atmospheres).
Remove the housing cover from the relay.

Pressure limit adjustment screws under the housing cover

Under the housing cover there are large and small nuts with springs; when the large nut is rotated clockwise, the locking spring is compressed and the upper limit increases. The upper limit is decreased by turning the large nut counterclockwise.

Use the large nut to adjust the pump shutdown moment. best option- 2.5–3 atmospheres, let’s take 2.8.

Check the pressure in the accumulator, there should be a separate pressure gauge on it, let’s assume that it is 1.5 atm. Connect expansion tank to the relay.

Open the tap at the highest point of the water supply; if the pressure is not enough, use a bicycle pump to pump up the expansion tank to the required pressure.
Having opened the water, observe at what pressure gauge value the relay turns on the pump. Record the lower limit reading when the pump turns on when the pressure drops. Let us assume that this value will be 1 atmosphere.
2.8–1 - the difference between the lower and upper limits will be 1.8 atm., this is 0.3 atmosphere more pressure in the expansion tank.

The operating manual specifies that the lower limit pressure should ideally be 0.2 atmospheres greater than the pressure in the expansion tank. With this installation ratio, the number of switches for the electric pump is optimal, which significantly extends the operating life of the pump and relay. The difference can be corrected with a small bolt with a spring or by changing the pressure in the accumulator, pumping up or bleeding air. Correctly installed pressure switches RDM 5 "Gileks" will make the pump mode more economical, reduce energy consumption and last a long time.
