Due to everything is One divides into two., submersible sewage pump is the most critical problem is the usability problem, because the use of submersible sewage pump occasions in the liquid; transport medium containing solid material mixed liquid; the pump and motor is close; pump for the vertical layout, with the weight of the rotating parts the impeller under water pressure in the same direction. These issues have made the submersible sewage pump in the seal, motor carrying capacity, bearing arrangement and selection, and other aspects of the requirements than the general sewage pump to high.
In order to improve the life of submersible sewage pump, most domestic manufacturers are now in the protection of the pump system to find ways that the occurrence of leakage, overload and over temperature fault in the pump can automatically alarm and automatically shut down equipment repair. But we think, in the submersible sewage pump set protection system is necessary, it can effectively protect the safe operation of the electric pump.
But this is not the key to the problem, the protection system is only a remedy after the failure of the pump, is a more passive approach. The key to the problem should be from the fundamental, completely solve the pump in the seal, overload and other aspects of the problem, this is a more proactive approach. For this purpose, we put the Deputy impeller fluid power sealing technology and pump non overload design technology used in submersible sewage pump, the greater the pump seal reliability and bearing capacity, to extend the service life of the pump.
