Submersible sewage pump running in the indicator pointer to the current table pointer has the following two main reasons:
1. The moving water level drops below the water level, the main reason that causes the water outlet of the water pump is the flow rate of the submersible pump is too large or the depth of the bottom is not enough, the treatment method is as follows.
Customs small water outlet pipe of the submersible pump valve, reduce the pump flow to move to lower the water level, the water inlet of the submersible pump is always below the surface of the water.
The increase of depth of the submersible pump to move to lower the water level, water inlet of the submersible pump is always located under the water.
2. Non clogging sewage submersible pump rotor damage caused by the motor can not work properly, speed down, pump flow, head drop, the current table pointer swing. The processing method is to replace the rotor.
