Centrifugal pump capable of effectively improving corrosion resistance of inner wall

Abstract

The invention discloses a centrifugal pump capable of effectively improving the corrosion resistance of the inner wall, and belongs to the technical field of centrifugal pumps. The centrifugal pump comprises a motor, a disc, a bottom cover, a pressing contact assembly, a lifting side column assembly, an inner wall maintenance assembly and a maintenance liquid release assembly; the motor and the bottom cover are fixedly mounted at the top and the bottom of the disc correspondingly; the pressing contact assembly and the lifting side column assembly are arranged in the bottom cover; and impeller blades are fixedly mounted at one end of an output shaft of the motor through a rotating shaft. The maintenance liquid release assembly is mounted in the disc, the inner wall maintenance assembly is driven to move, a shifting piece sleeve on the side surface of the inner wall maintenance assembly can effectively touch a side plate of the maintenance liquid release assembly in the disc, the side plate generates certain displacement, thus maintenance liquid in the maintenance liquid release assembly is sprayed through a piston and is sprayed to the inner wall of the disc, at the moment, the inner wall maintenance assembly rotates, the interior of the centrifugal pump can be maintained along with the maintenance liquid, and the anti-corrosion effect of the inner wall in the centrifugal pump is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of centrifugal pumps, in particular to a centrifugal pump which can effectively improve the anti-corrosion ability of the inner wall. Background technique [0002] Centrifugal pump refers to the pump that transports liquid by the centrifugal force generated when the impeller rotates. The centrifugal pump works by using the impeller to rotate to make the water centrifugally move. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The pressure water pipeline flowing into the water pump.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the traditional centrifugal pump is not provided with any anti-corrosion structure on the inner wall, resulting in poor overall anti-corrosion effect in the centrifugal pump. After a period of use, the traditional centrifugal pump is prone to corrosion, resulting in centrifugal There is a problem of failure in the pump, and a centrifugal pump that effectively improves the anti-corrosion ability of the inner wall is proposed
