       How to improve the life of the submersible sewage pump?

     In order to improve the life of submersible sewage pump pump, and now most of the foreign and domestic manufacturers have to find a way to in the protection system of the pump, namely in the pump leakage, overload and overtemperature of failure can automatically alarm, and automatically stop for repair.However, we believe that it is necessary to set up the protection system in the sewage pump, which can effectively protect the safe operation of the electric pump.
     But this is not the crux of the problem, the protection system is only a remedy after the pump failure, is a more passive method.The key point of the problem should be to start from the root and solve the problem of the pump in sealing and overload, which is a more active way.Therefore we deputy hydrodynamic impeller sealing technology and the overloading of the pump design technology (valves, pumps) used in the diving sewage pump, improve the pump seal reliability and carrying capacity, prolong the service life of the pump.
     The drainage pumps used in the building include submersible sewage pumps, drainage pumps, vertical sewage pumps and horizontal sewage pumps.Since the general site of the building is small and the displacement is not large, the drainage pump can be preferred to use the submersible sewage pump and the drainage pump, which is generally used in important places.Vertical sewerage pumps and horizontal sewerage pumps are required to set up isolation foundation, self-irrigation water absorption, and occupy certain space, so they are less used in buildings.
     Everything has two sides, the most critical problem for the sewage pump is reliability, because the use of the sewage pump is under the liquid;The medium is a mixture of liquid containing solid materials;The pump is close to the motor;The pump is vertical, and the weight of the rotating parts is the same as that of the impeller.All these problems require that the sewage pump is higher than the average sewage pump in sealing, motor bearing capacity, bearing arrangement and selection.
