In order to improve the service life of the submersible sewage pump, most manufacturers at home and abroad think of ways in the pump maintenance system, that is, when the pump has leakage, overload, overtemperature and other problems, it can stop the automatic alarm, and automatically stop for repair.
However, we think it is necessary to set up a maintenance system in the sewage pump, which can effectively maintain the safe operation of the electric pump. But this is not the key to the problem. The maintenance system is just a way to make up for the pump failure. It is a more passive method. The key to the problem is to start from the basic point of view and thoroughly deal with the problems of pump sealing, overload, etc., which is a more active method.
Therefore, we apply the power seal technology of the auxiliary impeller and the non overload design technology of the pump to the submersible sewage pump, which greatly improves the reliability of the pump seal and the bearing ability, and extends the service life of the pump.
