Repair of the pump station: the most common problems and their solutions

Automation of pumping stations is a necessary condition for the uninterrupted supply of country estates potable water from wells and boreholes. In the absence of centralized water supply this scheme has a number of features related to ensuring stable operation of the Electromechanical components of the pumping station.

Principle of operation of the pumping station

The abstraction of water for domestic use leads to a decrease of the working pressure in the network, and automation includes a pump that draws water from a natural source. Occur excessive load takes on the pressure, working in cooperation with automatic on/off pump stop working once the system pressure is restored. the Frequency of switching on and off of the pump and the automation should be as small as possible, in order to prolong their service life. This will mean trouble-free operation of most pumping stations.

However, the owner of a country residence should be ready in the event of failure to find its cause and to repair the pumping station. The following are the basic signs of emergency situations and actions in accordance with them.

1. The station operates. The pump is activated. The water is not swinging

Check the tightness of pipelines, pump filling water, operation of the check valve. Check the well or wells of water. Possible a lot of product in the gap between the impeller and the pump body (replace parts or the entire pump). Also possible low voltage network.

2. The station operates. The pump is activated very often. The water is choppy bobs

To Test the dynamics of the gage. If there is a sharp pressure drop up to the moment of switching on:

• Ruptured membrane (diaphragm) pressure tank needed replacement;
• In the tank of the accumulator there is insufficient air pressure; to spool or to seal leaks;
• Defective pressure switch which turns on/off the pump.

3. The station operates. The pump is activated. Water is on and off

4. The station operates. The water goes. The pump is not turned off

Repair of the pump station is to adjust a pressure switch for setting new values of the upper and lower limits at which turns on/off the pump. You may need to clean the inlet relay, clogged with salts.

5. The station is not working - does not turn on the pump

Check the power supply of the station. Inspect the contacts on the pressure switches and clean them if they get burned. to Test the motor. The characteristic smell of burning insulation will clearly indicate its failure. In this case, repair of the pump station must only be carried out specialists.

6. The station is not working - the pump makes a buzz, but it is not enabled

Most Likely, the pump station all winter were stored in the not-too-adapted to this area. The impeller of the station, which remained a long time without movement, and in the absence of water "stuck" to the body. Repair of the pump station in this case is simple: turn off pump, rotate the impeller manually and re-enable the network.

In conclusion, it is worth noting that automation of the pumping station helps without constant attention to keep optimal parameters of its operation with the network of a household pressure, the same in the urban centralized water supply systems.
