Abstract
The invention provides a novel cutting-type submersible sewage pump. The novel cutting-type submersible sewage pump comprises a motor component, an oil chamber, a valve body and a valve seat. An impeller and a cutting head are connected at the lower end of a motor rotor on the motor component and rotate synchronously along with the motor rotor to extract sewage out and tear and cut off substances such as long fibers, bags, belts, weeds and cloth strips in the sewage, so that the sewage is drained smoothly. Under protection of a cable sheath, a cable is insulated and waterproof effectively. Annular reinforcing rings with the hollow middles are used for reinforcement among vanes without affecting water inlet efficiency. Blades of the cutting head are in a sharp triangular pyramid design to be good in cutting effect and are reasonable in number, so that poor cutting quality caused by the fact that cut substances are too long due to too few blades and insufficient cutting force caused by too many blades are avoided. The novel cutting-type submersible sewage pump has the advantages of high extraction efficiency and cutting efficiency, good cutting effect and smoothness in sewage drain.
