Reasons for frequent start of ordinary automatic booster pumps

The automatic booster pump can start and stop automatically, but it may also face some minor problems.
For example, even if you don’t have water, it may start and stop frequently by itself. Even the frequency conversion automatic booster pump may also happen.It starts frequently when not using water.The possible causes and solutions for frequently starting booster pumps are:

1. The one-way valve of the fully automatic booster pump is not well sealed and does not maintain pressure. The pressurized water will flow back to the pipeline from the gap of the one-way valve, causing the pressure to drop to the lower start limit, so the booster pump Will start. When the booster pump is started to increase the pressure, it will shut down to maintain the pressure, and the pressure will be maintained for a period of time because the seal will not flow back and reduce the pressure, and the booster pump will start again. Such a reciprocating cycle causes the automatic booster pump to start and stop frequently when no one is using water. The solution is: after the booster pump is pressurized, immediately turn off the power of the automatic booster pump, and observe from the pointer of the meter whether the pointer is falling for a certain period of time. If it is and no one is using water, 100% is determined The check valve is not well sealed and leaks. The solution is to replace the one-way valve.

2. There is a water leak somewhere in the front end of the pipeline where the automatic booster pump is installed. The pressure drop caused by water leakage is normal for the booster pump to start automatically. This is not difficult to solve. Turn off the booster pump power. If there is no water, observe whether the water meter is turning. If it is turning, it means that there is water leakage. If the pipe is leaking, the pipe can only be replaced.

3. The sensor of the automatic booster pump is faulty. Sensor failure will cause the feedback pressure data to be inaccurate, so it will cause the controller to make a wrong judgment and automatically start, and the pressure will stop again. If the above two possibilities are ruled out, it is a sensor failure. Generally, contact the merchant to replace the sensor.
