A magnetic drive centrifugal pump structure resistant to strong corrosive chemical medium

By introducing a rotatable filter cartridge, graded magnetic impurity adsorption, and a dry-run fault-tolerant return water system into the magnetically driven centrifugal pump, the wear and buildup problems of traditional magnetic pumps in highly corrosive media are solved, achieving efficient self-cleaning and protection, and ensuring reliable operation of the equipment under high-temperature and highly corrosive conditions.

Abstract

The application relates to a magnetic driving centrifugal pump structure resistant to strong corrosive chemical medium, which comprises a pump body and a working end, a filtering end for filtering the medium is arranged above a water inlet at the top of the working end, and a backwater end for fault tolerance of dry running is fixedly connected to the top of the working end; the application relates to the technical field of centrifugal pumps. The magnetic driving centrifugal pump structure resistant to strong corrosive chemical medium realizes online self-cleaning filtration based on fluid power: a rotatable filter cylinder is arranged in a pipeline, an impeller is installed at the top of the filter cylinder, and the impeller and the filter cylinder are driven to rotate by the impact force of the downward flow of the medium. The push plate on the surface of the filter cylinder continuously pushes the intercepted solid impurities to the edge of the output section during the rotation, the impurities are automatically gathered by centrifugal force and fluid scouring, and the defects that the traditional filter screen needs to be frequently stopped and cleaned due to blockage are avoided.
