Promotion of some practical new patented technolog

The utility model discloses a crushing sewage pump, which aims to provide a spiral water pump used for discharging sewage and sandy stone water. It includes a rigid rigid helical rotor, an elastic colloidal helical stator and a pump shell. The rigid helical rotor is spirally sleeved in the colloidal helical rotor, and the colloidal helical rotor is nested in the pump shell. The water inlet end of the rigid helical rotor is provided with a tooth piece, the inner wall of the pump shell is provided with a water baffle, the water inlet end of the pump shell is nested with a tooth ring, and the opposite end faces of the two have a micro gap. The utility model avoids the occurrence of dirt blockage and filament winding, and has the advantages of high lift, low energy consumption, simple operation, convenient use, high work efficiency, durability and long service life; It is suitable for drainage and irrigation of various sewage

sewage pump with dual functions of cutting and backwashing

application number/patent number:

the utility model relates to a sewage pump with dual functions of cutting and backwashing. The utility model comprises a motor, a rotating shaft, a pump body, an impeller and a base, which is characterized in that: the front end of the impeller is connected with an impeller front knife, the impeller front knife is located outside the water inlet of the base, and there are backflushing holes on the pump body and the base. The edge of the water inlet of the base is in a flower tooth shape, and the front end of the blade of the impeller corresponds to the base. The utility model has the advantage of preventing the use of coolant in the cutting process, which is that it can realize the dual effects of cutting and backwashing on a sewage pump, and improve the application range of the sewage pump
