Abstract

The invention relates to the technical field of centrifugal pump accessories, in particular to a centrifugal pump cover. According to the technical scheme, the centrifugal pump cover comprises a pump cover body, a shaft hole is formed in the central of the pump cover body, a shaft hole base is arranged on the periphery of the shaft hole, a plurality of divergent reinforcing ribs are arranged on the outer side of the shaft hole, mounting holes and through holes are formed in the pump cover body, and the pump cover body comprises a pump cover inner layer and a pump cover outer layer which are coaxially arranged in a sleeving manner; a reinforcing part is arranged between the pump cover inner layer and the pump cover outer layer, and the pump cover inner layer, the pump cover outer layer and the reinforcing part are welded into a whole in a high-frequency manner through brazing filler metal filling. The centrifugal pump cover has the beneficial effects that the reinforcing part is arranged between the pump cover inner layer and the pump cover outer layer and is an I-shaped pressing-resisting beam, due to design of the I-shaped pressing-resisting reinforcing part, the whole strength and pressure resistance of the pump cover can be improved, weight cannot be increased too much, and in addition, the reinforcing part can achieve the heat transmission and heat dissipation effects.

Description

technical field [0001] The invention relates to the technical field of centrifugal pump accessories, in particular to a pump cover of a centrifugal pump. Background technique [0002] The centrifugal pump works by using the centrifugal force generated by the water generated by the rotation of the impeller. Before the pump starts, the pump casing and the suction pipe must be filled with water, and then the motor is started to make the pump shaft drive the impeller and the water to rotate at a high speed. Under the action of the impeller, it is thrown out of the impeller, and flows through the pump casing into the pressure water pipeline of the water pump. The pump cover is the main part of the centrifugal pump. The existing pump cover has simple structure, insufficient strength, short service life and needs to be replaced frequently. Therefore, a new technical solution should be provided to solve the above technical problems. Contents of the invention [0003] The object ...
