I am from Rostov, this is the second time I have contacted this company and for the second time they have helped me out, despite the bad weather and weekends. It’s also nice that they think through everything down to the smallest detail and when you tell us the brand of the pump, they take with them all possible spare parts for it. Such a thoughtful approach is very rare these days. By the way, in Rostov at the Screwdriver SC, they kept me busy for half a day on Friday, waiting for a call, and then they offered to postpone the repair to Monday. And then the master arrived on Saturday morning and did everything. Thank you

We will arrive at a time convenient for you, find the problem and fix the problem.

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 automation options for pumps that have a long service life 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 various 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.

We offer for sale modern automation units for pumps manufactured by Gilex. Before you buy an 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 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. Having chosen a convenient location for the pressure gauge, plug the hole on the opposite side with a screw without using any seal. Install the automation unit strictly in a 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″) was connected to the direction of water flow from the pump, and the side outlet (1″ male thread) 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 thermal resistance not lower than 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 the 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 in the very top 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.

1 Total pump automation

Gilex Crab automation unit is a device that automates the operation of an electric pump. It turns on the system when the pressure decreases (the valve opens), and turns it off when the flow stops (the valve closes). Automation also consists of protecting the pumping station when it is “idle”—working without water, on “dry running.”

The automatic Gilex block applies only to clean water that does not contain solid elements. If the latter are available, then you need to separately purchase a filter element for the automation unit. And if you install a pressure gauge, the pressure can be monitored visually.
to menu

1.1 How does it work?

The automatic unit Gilex 9001 turns on 30 seconds after connecting to the power supply. It then turns off and goes into sleep mode. Further switching on of the device occurs when the pressure changes - the valve opens and closes.

As soon as the pressure level drops to the minimum permissible norm, the automation control element will turn off the pump. This significantly extends the safety and performance of the device.

After reducing the pressure to minimum permissible level the system will not turn off immediately, but after several tens of seconds (usually from five to twenty, depending on the specific model). The delay in turning off the pumps is necessary so that, when weak pressure water, it systematically did not turn off. This allows you to extend the life of the system.

1.3 Installation

To automate the control of the pump, you need to purchase the appropriate additional components for it (depending on your needs), and connect them in the following sequence:

The pressure gauge is attached to the automatic unit on the side using the fasteners included in the kit. Which side to mount on is “a matter of discretion.” But, it is important to carefully secure the device to the panel without using sealing elements.
The automation unit is mounted exclusively in a vertical position. It can also be mounted in any convenient location, but in the segment between the tap (the first water intake point) and the pump supply system. Moreover, this must be done so that the external inlet of the system is adjacent to the water outlet channel from the pump, and the side outlet is adjacent to the water flow in the pipe.
All connections must be tightly fixed. It is worth making sure that they are tight and double-checking that all connecting elements are connected correctly.
If automatic equipment is used for electric pumping systems with a maximum pressure threshold of 15 bar, then a pressure reducer is mounted at the automation input.
The device housing (or circuit board) contains electrical diagram automation connections. Follow it strictly when connecting! If a single or three-phase pump with an operating current of more than 10 Amps is used, the automation must be connected via an electromagnetic starter. The cable used to connect the device must be resistant to elevated temperatures(above 100 degrees) and non-flammable.

Automatic adjustment and operation of systems (minimum pressure) is designed for a pressure of 2 atm. This option is the most common and optimal for most systems. But, this parameter can be easily adjusted if necessary. This is done by rotating the tap, which is located on top of the automatic system and has “plus” and “minus” markers.

1.4 Starting the automatic system

Important! When the incoming water level is lower than the level at which the pumping system is installed, it is imperative to install a check bottom valve on the inlet pipe.

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 as long as the automatic system operates. If after such manipulation the flow is still missing, you need to repeat the launch.

1.5 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.

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 a large nut to adjust the pump shutdown moment, the best option is 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 the expansion tank to the relay.

Open the tap at the highest point of the water supply; if the pressure is not enough, pump it up with a bicycle pump 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 than the 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. Right installed relays pressure of RDM 5 "Gileks" will make the pump mode more economical, reduce energy consumption and last a long time.

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 the required pressure in the network is maintained by the RDM 5 pressure switch. The device allows you to automate the process of water supply in autonomous water supply systems.

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), it triggers spring valve 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 goods Not suitable for everyone for the following reasons:

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

In the above cases, the system automatic feeding water will have to be collected from separate elements, and the pressure switch will have to be adjusted 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 satisfy 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 to electrical network.

Connections of external and internal pipelines must be verified by tests 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.

1 Features of the company's 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 movable mechanism, closing the contacts when the pressure decreases. For external monitoring of device operation in lateral surface There is a pressure gauge built into the unit.

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.
to menu

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.

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.

2 Correct installation of the device

Automation Gilex 9001 is installed in the supply line complete with additional equipment. That's why important stage is correct installation and setting up 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 pumping device works throughout the entire period of use of the faucet. 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, 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 Other automation options Gilex

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;
filter with 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. Required condition when using RDM-5 there is high-quality grounding.

4.2 Gilex 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 area 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.

Design and principle of operation of automation for the pump

Exist different means automation 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. Newest electronic devices are considered the most effective due to high-tech equipment, advanced functionality and finer 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”).

Design and principle of operation of a water pressure switch

Structurally, the relay is made in the form compact block with springs of maximum and minimum pressure, the tension of which is adjusted 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 you to ensure constant pressure and the required water pressure in the system. 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 tank’s volume 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 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 power of the pumps is chosen such that it does not allow pumping the tank 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 own version 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.

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 reverse side- decrease. 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.
