Abstract

The invention provides a cutting assembly for a stainless steel cutting submersible pump, belonging to the technical field of water pumps and solving the problems of low cutting performance and poor blockage resistance existing in the traditional cutting assembly of the stainless steel cutting submersible pump. The cutting assembly of the stainless steel cutting submersible pump comprises a static cutting pair with a circular through hole and a dynamic cutting pair coaxially penetrating in the through hole; a medium channel by which a medium goes from one port of the through hole of the static cutting pair to the other port is arranged between the outside part of the dynamic cutting pair and the inner edge of the static cutting pair; the outside part of the dynamic cutting pair is provided with a dynamic cutting edge part; and the inner edge part of the static cutting pair is provided with a static cutting edge part opposite to the dynamic cutting edge part and used for forming the cutting pairs. The cutting assembly for the stainless steel cutting submersible pump only comprises the static cutting pair and the dynamic cutting pair and has the advantages of simple structure and reasonable design and layout.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and relates to a stainless steel cutting submersible pump, in particular to a cutting assembly of the stainless steel cutting submersible pump. Background technique [0002] Sewage pumps are a kind of centrifugal impurities, which can be divided into submersible type and dry type according to the working form. It is mainly used to transport urban sewage, feces or media containing solid particles such as fibers and paper scraps in the liquid. Since the conveyed medium contains fibers that are easy to entangle or bunch, the flow path of this kind of pump is easy to be blocked. Once the pump is blocked, the pump will not work normally, and even the motor will be burned, resulting in poor sewage discharge. Bring serious impact to urban life and environmental protection. Therefore, anti-clogging and reliability are important factors for the quality of sewage pumps; those skilled in the art usual...
