Abstract
The utility model discloses a centrifugal water pump shaft. The centrifugal water pump shaft comprises a main shaft and an inner shaft, wherein the inner shaft is arranged in the main shaft; a lug is arranged at the inner side of the main shaft, and a slide groove matched with the lug is formed in the outer surface of the inner shaft; and a cross groove is formed in the main shaft and mutually clamped with a slide block. The centrifugal water pump shaft disclosed by the utility model is compact in structure, reasonable in design, and high in stability.
Description
Technical field
The utility model relates to water pump field, refers to especially a kind of centrifugal water pump shaft.
Background technique
The centrifugal water pump of selling on market at present, general volume is all very large, corresponding supporting centrifugal water pump axis body amasss also relatively large, such situation, just causes installing difficulty, cause dismounting inconvenience, finally can affect later period maintenance, because do not have fixed hole to fix centrifugal water pump, while causing high-speed motion, be offset, affect efficiency, even accidents happened.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of compact structure, reasonable in design, the centrifugal water pump shaft that stability is high.
The technical solution of the utility model is achieved in that a kind of centrifugal water pump shaft, comprise main shaft and interior axle, described interior axle is arranged in main shaft, described main shaft inner side is provided with projection, described interior axle arranged outside has the chute matching with described projection, on main shaft, be also provided with translot, main shaft end is also provided with installation through hole.
As preferred version, described translot comprises the first translot and the second translot.
A kind of centrifugal water pump shaft of the present utility model, compact structure, reasonable in design, stability is high.
