Pressure relay apparatus
The installation of such equipment to the pumping station can store the pressure in the water supply system in a given range. The result is a uniform pressure with the necessary force. A properly configured upper level, and lower boundaries of such an indicator provides a periodic shutdown of the pumping station. This helps extend the life of the water equipment and its trouble-free operation.
The operating principle of a water station
Constant and continuous repetition of this cycle - a guarantee of reliable, trouble-free operation of the equipment, constant pressure in the water system.
Proper configuration of the pressure switch
Once the pumping station is installed and connected, special attention should be given to setting up a water pressure switch for the pump. From the correctness of the maximum levels will depend on the work of the entire system.
Water pressure switch
To do this, first of all, you need to check up on what indicators tank was set at the factory. Standard minimum level of about 1.5 atmosphere, and the maximum - 2.5. You can check this conventional mechanical pressure gauge with an empty tank and disconnected from the power supply pump. Due to the fact that this device has a metal body, its readings are more accurate than those of counterparts made of plastic. To measure pressure, spun a little cap on the empty tank housing, then connected a pressure gauge and take readings.
Adjusting the pumping pressure relay station is carried out using large and small springs
Useful advice! When buying a ready-made stations such verification may not be required. If the equipment bought separately (pump relay tank), the initial setup is required.
Subtleties adjust water pressure switch for the pump
To set the pressure level specific values needed to carry out adjustment of the water pump pressure switch. To do this, perform the following manipulations:
- Fill tank to until the gauge indicates the required maximum value.
- Turn off the pump station.
- Opening the switch housing, should gradually rotate the small size of the nut until it trips the internal mechanism. Clockwise rotation - pressure increase level - against reduction.
- For the parameter of the lower water tank is gradually drained by opening the valve.
- As soon as the gauge rose to the desired mark, the flow of water stops.
- To adjust the low pressure indicator Rotate the large nut, and to the resistance of contacts.
Electronic water pressure switch
In a small range between the upper and the lower limit pressure, the pumping station pumps up enough water to create a water system constant average level of that index. Water pressure in this case will be uniform, comfortable. If, however, by adjusting the water pressure switch for the pump is set over a wide range, the inclusion of the equipment will occur less frequently. With this configuration, the station will be less likely to be included, and will last much longer.
Driving LP3 relay mounting
Useful advice! When adjusting it must be remembered that the minimum difference between the lower and upper limit can be not less than 1 atmosphere.
Protection against "dry run"
Quite often the cause of failures in the operation of the pumping stations is the lack of water in the system. The load on the pump is carried out without water, leads to a deformation of the internal parts and the failure of all equipment.

Absence of fluid in the system can be caused by the following reasons:
- fluid intake is considerably greater than the volume of a well or borehole;
- interruptions in the water supply in the summer;
- on the water systems of the accident.
Scheme of the surface water pump pressure switch
To guard against such troubles, there are relay with protection against dry running. This equipment provides the possibility of contact separation, at which the complete shutdown of the pump. Typically, this indicator is set by the level of about 0.5 atmospheres and is not subjected to correction. Start engine pumping station can only be in the recovery of normal amounts of water in the system.
Scheme of dry run relay
Also, manufacturers may offer another type of protective equipment. Flow switch, augmented functions pressure switchAlso effectively protects against breakage in the absence of water. This sensor shuts down the system in the absence of flow or pressure drop is less than 1 atmosphere.
Useful advice! When adjusting the water pressure switch to the pump should be mindful of the power declared by the manufacturer of the station. If the station can not supply water pressure to 5 atmospheres, then customize it to a large point makes no sense.
