When the submersible pump leaks, it will cause insulation damage, bearing immersion, alarm system alarm, forcing the equipment to stop operation.
The main reason is that the dynamic seal (mechanical seal) or static seal (cable entrance special seal, type 0 seal) of submersible pump is damaged due to water leakage, power line or signal submersible pump cable damage leads to water seepage. Should stop all kinds of alarm signals, such as flooding, leakage, humidity, etc. Before installation, check the quality of each sealing part; The end face of each sealed component shall ensure good contact during installation; Check the phase and ground insulation resistance of the motor and each alarm before operation. Whether the sensor components of the system are intact. Replace all damaged seals and cables and dry the motor in case of the above failure during operation. Disassembled seals and submersible water pump cables shall not be used.
Reverse submersible pump when stopped:
1. The pump will be reversed when the pump motor is power off. The main reason is the failure of check valve or flapping wing door in the outlet pipe.
2. Check and eliminate measures before installation. Check valve should be installed in the correct direction. The center of the door should be aligned. Open and close should be flexible. Check check valve or submersible pump cable when operating, repairing or replacing damaged check valve or door.
