In order to improve the life of submersible sewage pumps, most domestic and foreign manufacturers are trying to find ways to improve the pump protection system, that is, to automatically alarm and automatically shut down for repair when the pump leaks, overloads, overheats, etc.
However, we believe that it is necessary to set up a protection system in the sewage pump, which can effectively protect the safe operation of the electric pump. But this is not the key to the problem. The protection system is just a remedy after the pump fails, which is a relatively passive method. The key to the problem should be to start from the root and thoroughly solve the problems of the pump in terms of sealing, overload, etc. This is a more active method.
For this reason, we apply the auxiliary impeller fluid dynamic sealing technology and the pump's no-overload design technology to the submersible sewage pump, which greatly improves the pump's sealing reliability and load-bearing capacity, and extends the pump's service life.
