Abstract
The utility model relates to the technical field of accessories of a centrifugal pump, in particular to an enhanced centrifugal pump cover. The enhanced centrifugal pump cover comprises a main pump cover body, wherein a shaft hole for mounting a pump shaft is formed at the center of the main pump cover body; a convex ring is arranged at the center of the main pump cover body; mounting holes and through holes, which are fixedly connected with the pump body are formed at the surface of the center of the main pump cover body; the mounting holes are formed at two sides of the convex ring; reinforcing ribs are arranged between the convex rings and the through holes. The enhanced centrifugal pump cover is simple in structure, reasonable in design, long in service life, and free of frequent maintaining and replacing, and the work efficiency can be improved.
Description
Technical field
The utility model relates to centrifugal pump accessory technical field, especially a kind of reinforced centrifugal pump cover.
Background technique
Centrifugal pump is utilize vane rotary and make the centrifugal force of water generates carry out work.Water pump, before startup, must make to be full of water in pump case and suction sleeve, and then starting electrical machinery, makes pump shaft impeller and water do high speed rotary motion, and water, under the effect of centrifugal force, is thrown toward impeller outer edge, flows into the setting-out pipeline of water pump through the runner of volute pump case.Pump cover is the critical piece of centrifugal pump, and traditional pump cover structure is complicated, and manufacturing process is complicated, and working life is not long, need often change.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the centrifugal pump cover of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of reinforced centrifugal pump cover, there is pump cover main body, described pump cover main center has the axis hole of installing for pump shaft, pump cover main center is provided with bulge loop, pump cover main center surface is provided with mounting hole and the through hole being fixedly connected with the pump housing, mounting hole site, in the both sides of bulge loop, is provided with stiffening rib between bulge loop and through hole.
Further, the diameter of described mounting hole is less than the diameter of through hole.
Further, described pump cover main center surface is provided with 3 through holes.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, and long service life does not need frequent maintain and replace, can increase work efficiency.
