How to run the pumping station?

Supplement Article - Surface pump, water pump station

Before commissioning, the pump must be filled with water:

• Unscrew the filler plug or open the filling valve;
• Fill pump and suction pipe as long as it does not pour over the edge;
• Screw the plug (to close the filler valve).

For automatic supply station before turning to check the air pressure in the accumulator, which should be about 1.4-1.5 atmospheres. Monitor the pressure level in the accumulator by using a conventional tire pump. If pressure is insufficient, it must be lifted to a desired level by using an air pump.

The recommended pump start-up procedure:

• Fill pump and suction pipe;
• Close the valve;
• Start the pump into the wall socket;
• Slightly lift the valve to provide air outlet residues from the pump.

- let the pump run for 1-3 minutes - during this time of the pipe at the outlet water should. If the water did not go to the pump, pour in the water pump must be switched off and repeat the pump start-up procedure.

After starting the pump station is necessary to test the functionality of automation.

Properly functioning relay must turn off the pump when the system pressure reaches the upper level relay settings, and turn on the pump when the pressure drops below the lower level of the relay settings. If necessary, it is possible to carry out pressure switch setting required to turn off the pump and the pressure within the pressure developed by the pump.

Pressure switch type RM-5 has a setting range from 1 to 5 bar.

Adjust the pressure switch is carried out in the current system.

Adjust the pressure switch

•  Unscrew the plastic fastening screw (1), to remove from the relay cover (2).
• By rotating the nut (3) to adjust the lower limit of the working range, i.e. pressure below which the pump switch occurs. Clockwise rotation increases pressure pump switching; counterclockwise - reduces.
• By turning the nut (4) to adjust the pressure difference between the pump on and off, i.e. configurable upper limit of the operating range, above which the pump is disabled. Clockwise rotation increases the difference between the upper and lower setting; counterclockwise - reduces. Here configured earlier start pressure (lower limit of the working range) does not change.

Values ​​adjusted pressure is monitored on the pressure gauge at the closing and opening of the valve (2) the figure above.

IMPORTANT!

Upper relay setting (pump OFF pressure) should not exceed the pressure which the pump can actually develop in the particular operating conditions.

Make sure that when you close the tap pump develops a need to turn off the pressure and switch off the pump.

Avoid prolonged operation of the pump (10 minutes) to a closed valve (i.e. in the absence of water intake). It is fraught with rapid heating of water in the pump housing to a high temperature and can lead to thermal deformation of parts of the pump.

Operation and maintenance of the pump

During operation, do not leave for a long time unattended running pump or pumping station. During the operation of the equipment may have various emergency situations, the damage from which will be minimal at timely response.

Also, do not leave for a long time unattended connected to the network pumping station (even broken).

With proper installation and compliance with operating conditions of the pump (pump station) is virtually maintenance free.

For station it is recommended once a month, as well as after long periods of inactivity before starting to check the air pressure in the accumulator.
