Description

Corrosion-resistant rubber-lined rotor pump

Technical Field

The utility model belongs to the technical field of rotor pumps, and particularly relates to a corrosion-resistant rubber-lined rotor pump.

Background

The cam rotor pump is a rotary positive displacement pump with positive displacement properties, the flow rate does not change with back pressure, and the working volume is changed by the relative movement between the rotor and the pump body. The cam rotor pump relies on two synchronous counter-rotating rotors to generate suction force (vacuum degree) at an inlet in the rotating process, the two rotors divide a rotor chamber into a plurality of small spaces so as to suck materials to be conveyed, therefore, the peripheral walls and the two side walls of the two rotors are always in a structure with the inner cavity wall of the pump body, the outer wall of the existing rotor is coated by all rubber, although the existing rotor has certain wear resistance, after a long-time operation process, the situation of liquid leakage can occur in the long-time rotating process due to the fact that the rubber coated position is connected with the supporting piece, so that internal media seep out from the connecting position, and the inner cavity wall of the rotor or the pump body is worn or corroded by the media, and therefore, the applicant provides a corrosion-resistant rubber lining rotor pump.
