Pump body and motor of submersible sewage pump is integrated. Before leaving the factory, our company will test the products and ensure the quality of the product. For the motor burnout situations, the common reasons are as follows:
1. There is something wrong of pump installation.
Installer does not lower the water pump with TAB on the pump, but by pulling the cable. Submersible sewage pump is totally closed, thus, if pulling the cable, seal of cable will be damaged and water will be into the pump body and finally burn out the motor.
2. There are many foreign particles or fibers and sundries.
Submersible sewage pump is used to pump and deliver sewage and cannot deliver silt and sundries, for silt and sundries will clogged pump body and burn out the motor.
3. The pump is idling.
Submersible sewage pump is cooled by liquid. If the liquid level of tank is lower than two thirds of pump body, the pump will be burned out due to high temperature of pump body.
4. Super current.
The super current at pump usage process will burn out the motor. The common super current situations are: the actual head is too larger or smaller than that of selected model, concentration of liquid is too large and three-phase current is imbalance.
