Water pressure switch for the pump: adjustment of the accumulator of the pump station, self-adjustment

Water pressure switch - an important component of the water supply system The installation of water supply systems is not an easy process, and it is not as easy to implement it with your own hands as it might seem at first glance. When installing, it is necessary to install a pump, as well as a water pressure switch, which will allow to regulate the process of supplying liquid through the pipes of the house. The adjustment of the pumping station is important, and it is a small unit that facilitates the activation of the pump when the pressure in the system decreases, and the shutdown when reaching the maximum level.

Purpose of the pressure switch

In order for the water pump station to function properly( turret-free), it is necessary to install and adjust the accumulator, and also a relay, for example, PMM Type PM5 with a Vortex pump. Even if self-made equipment is installed for the water supply system at home in the country, a lot is required.

The correct operation of the water station is ensured by a properly configured accumulator and pressure switch

Namely:

• Accurate calculation of all parameters;
• Accounting for water supply features;
• Competent and professional approach.

These 2 units must be connected to the pump, the relay should be located in the middle and closer to the accumulator. There are relay models that can be mounted directly to the surface of the pump casing, even to the submersible type. The installation of the water supply system must be correct, and therefore it is worthwhile before assembling it to become familiar with the principle of operation of each component.

The accumulator is called a container, inside which is an elastic pear and a membrane dividing it in half.

In pear air is located with a specific pressure, and in the membrane water. The pressure that is set in the pear and how much water enters the membrane depends directly on the amount of air pumped. The more it is, the higher the pressure in the system. As a rule, only half the water is pumped into the cavity of the tank. For example, if a tank can fit 100 liters according to the manufacturer's data, 40-50 liters will be there. The optimum pressure in the water supply system, especially when connected to household appliances, is 1.4 atm -2.8 atm, and such a device, such as a controller or a relay, must be installed in order to maintain it in this state.

Water pressure switch device

The hydraulic part is located on the rear side of the hydro-relay, the outlet can be with an external thread or an American nut. The second option is considered more convenient, since it allows for easier installation.

Having studied the device carefully, it is possible to install a water pressure switch in the most convenient way

In the first case, you will need to find special adapters with a union nut of a certain size.

It is possible to wind the product and thread, which is not always suitable. The connectors of the electrical part are located on the rear side of the case, and the terminal block for connecting the wires is installed under the cover cavity.

The hydro regulator is divided into 3 parts.

• Electric;
• Mechanical;
• Hydraulic.

The first group is a group of contacts that close and open, which is required to connect and disconnect the pump. The hydraulic part includes a membrane that acts on the metal base and a spring of a small and large type, whereby the pressure inside the pump is regulated, as well as the on or off.

Adjustment adjustments of the water pressure switch for the

pump

To set a specific value at the pressure level, it is necessary to correctly adjust the monitoring device. This will require a number of actions. Fill the tank until the pressure gauge shows the maximum value.

Adjusted water pressure switch allows the water supply system to work evenly

Next:

1. The station is switched off.
2. The relay housing is opened.
3. It is necessary to gradually unscrew a small nut before the internal mechanism triggers.
4. The rotation is clockwise, which increases the pressure level.
5. If you turn against, it decreases.
6. To establish the minimum value, a gradual drainage of water is required, due to the opening of the crane.

When the manometer reaches a certain level, the water drain stops. To adjust the lower pressure reading, the big nut is rotated just as before the contact is activated. The principle of operation of the device is simple, since by setting a small range among the upper and lower limits, there will be sufficient pumping of water by the pumping station, by creating a constant average level of the indicator. The system works evenly, which allows you to get the optimum head of water for comfortable use.

Steps for adjusting the pressure switch of the pump station

To configure the operation of the pumping station, the connection diagram is checked for compliance with the standard, for which the manufacturer's instructions can be used. Also it is necessary to put a reliable manometer, capable of giving out accurate indicators. It is installed in the water supply system at a short distance from the relay. To adjust the relay, it is necessary to twist 2 springs, namely large and small. Specialists recommend contacting professionals to connect and check the operation of the device.

A high-quality manometer installed close to the water pressure switch can give an accurate indication of the

This will allow:

• Be sure of serviceability;
• Get a quality guarantee;
• In case of problems, get free maintenance.

The automatic pressure regulator does not require intervention and is activated, that is, it turns on and off, if necessary. It is worth noting that it is not recommended to install an electronic device for regulating the water supply, since when the electric voltage is lowered, the water can not be pumped quickly. There are a number of points that should be familiarized with before submitting the pump to the well and connecting the pressure control relay. Not all models allow for the delta change, and therefore, when acquiring, you need to pay attention to this moment.

The relay can be covered with a waterproof and dustproof housing, which allows the product to be mounted directly on the surface of the pump, provided there is a suitable outlet.

It is possible to install an idle relay on the borehole pump, which has a separate housing, but there are models of a combined type regulator. Protection of idling is necessary to avoid breakage of the pump in the absence of water in the well. Such a device is best suited to a deep pump.

Operation of the pressure switch for the hydraulic accumulator

In any pump, the pressure is adjustable, and the maximum and minimum parameters must be set in the cavity of the storage tank, if it is a accumulator. This is how the relay switches off and turns on the machine.

Pressure switch turns on and off the accumulator

The hydrophore pressure can be increased or lowered, depending on:

• Volume of the consumed liquid;
• Frequency of consumption;
• Power of the pumping unit.

With regard to the characteristics of the pump, they can be found in the operating instructions or the technical data sheet. The standard value, due to which the working state of the relay is selected, is considered to be 1.0-5.0 atm. An adjustable mechanical relay or any other has a starting pressure of 1.5 atm, and the range of the motor in the pump is 2.5 atm.

The maximum pressure at which the relay starting device operates and the pump is switched off is 5 bar.

If the settings were knocked down during operation or installation, you must raise the upper edge yourself to a certain level and select a low pressure level. For this purpose, as already noted, a pressure gauge is required. The installation of the instrument is carried out on the collector in the accumulator, and the correction is carried out according to the readings on the manometer after the pump is switched off. Creation of pressure drops is realized due to the opening of the crane at the point of water extraction, which is closest to the accumulator.

To adjust the pressure control on the accumulator, you need the presence of the pressure itself and do not need to disconnect the pump from the electricity network. Due to the pump, the cavity of the storage tank is filled and the pressure in the water supply system rises. As soon as the controller is triggered and the engine is switched off, the plastic cover on the casing is removed and the tension on the small spring mechanism needs to be relaxed.

Adjusting the pressure switch and detecting the operation thresholds of the

The relay is an automatic device or in other words a blocking valve that creates a water supply process. The pump has 2 switching thresholds - bottom and top. Each of them depends on the pressure in that part of the accumulator, where there is air. The minimum pressure is considered to be a level of 0.1-0.2 atm or higher.

Having studied the technical characteristics and the performance characteristics of the pump model, it is possible to correctly adjust the water pressure switch for the high-quality operation of the

. If the pressure inside the tank is 1.4 atmospheres, the cut-off threshold will be 1.6 atm. Such parameters are considered optimal for automation operation.

It is necessary to take into account the parameters of the pump, which also has 2 values ​​in the form of the lower and upper threshold. Based on a number of indicators, the thresholds are selected. It is worth noting that the choice of the upper threshold, at which the pump is turned off, is automatic. The relay initially from the plant has a certain delta of the difference, configured during manufacture. In general, this difference is 1.4-1.6 atm. In other words, if a shutdown was manually set at 1.6 atm, the upper trip threshold is automatically set to 3.0 atm.

If the water supply system is connected to a large number of draw-off points, it is possible to add several atmospheres to the upper threshold for the maximum permissible value, but subject to a number of limitations.

Namely:

1. The controller parameters are taken into account.
2. All models have certain technical characteristics and performance characteristics.
3. As a rule, the upper limit of the pressure in the pump is set from the manufacturer and the pump must be switched off before it reaches an average of 0.2-0.4 atm.
4. If the upper threshold is 3.8 atm, then it will turn off when it reaches 3.6 atm.

For a long and efficient operation of the pump, it is best to make the difference between the thresholds as much as possible, since permanent overloads negatively affect operation. The peculiarity of the relay is that it is not necessary to clean it, which means that disassembly is not necessary, and if there is a weak water pumping, you need to pay attention to the work and clean the pump.

It is worth noting that if you work to connect and regulate the relay as carefully and without violating the recommendations from both the manufacturer and the above data, you can implement everything quickly and without problems. If there is no desire or minimal skills to work with such settings, it is better to entrust the process to a professional.
