1. The filter of the submersible pump is blocked
Blockage of the submersible pump’s filter screen will cause the water inlet of the pump to be unimpeded, and the water output of the submersible pump will be reduced. The treatment method is to remove the water plants and debris inside and outside the filter net and around the submersible pump. If necessary, use a bamboo basket or net basket to cover the submersible fire pump to prevent the entry of water and grass debris.
2. The rotation direction of the submersible pump is opposite
If the submersible pump rotates in the opposite direction, the water output will be very small. The treatment method is to change the position of any two phases at the connection point between the power supply cable of the submersible pump and the power supply.
3. The use head of the submersible pump is too high
The main reasons for the excessively high head in the use of submersible pumps are: the inappropriate selection of the submersible pump used, the specified high head, or the improper valve adjustment during the use of the pump, which makes the pump head too high. The treatment method is to adjust the use range of the submersible pump according to the specified range of use, or choose another submersible pump of appropriate specifications.
4. The impeller of the submersible pump or the flow channel of the pump body is blocked
The impeller of the submersible pump or the flow channel of the pump body is blocked, which will directly cause the submersible pump cannot work normally. The treatment method is to dismantle the inspection pump and remove the debris in the impeller of the pump or the flow channel of the pump body.
5. Submersible pump impeller or pump cover is worn
The treatment method is to dismantle the water pump, repair or replace the impeller or pump cover.
6. The water discharged from the submersible pump contains too many solid impurities or the viscosity of the water is too high
Too much solid impurities in the water or too high viscosity of the water will overload the submersible pump. The treatment method is to appropriately adjust the working position of the submersible pump or select another suitable specification sewage submersible pump.
7. The water level is too low or the pump is partially dehydrated
In the use of submersible pumps, the water level is too low or the pump is partially dehydrated, which causes the submersible pump cannot work properly: when the water level is too low, the pump will produce cavitation, and partial dehydration operation will make the submersible pump heat dissipation worse. The treatment method is to adjust the diving depth of the submersible pump, so that the submersible pump is always submerged in the water when it is working, which can ensure the normal operation of the submersible pump and is beneficial to the heat dissipation of the submersible pump.
