Nickel alloy pump shaft for petrochemical machinery

The nickel alloy pump shaft for the petrochemical machinery comprises a transverse shaft and a shaft sleeve, one end of the transverse shaft is fixedly connected with the end portion of a protruding shaft, a limiting device is installed on one side of the transverse shaft, the middle of one end of the shaft sleeve is fixedly connected with the end portion of a circular shaft, and the other end of the transverse shaft is fixedly connected with a circular plate. And a connecting device is mounted at one end of the convex shaft. Compared with the prior art, the nickel alloy pump shaft for the petrochemical machinery has the following advantages that through cooperation of the transverse shaft, the shaft sleeve and the limiting device, the transverse shaft drives the bolt to move left and right in the groove in the shaft sleeve, after adjustment is completed, the bolt is sleeved with the gasket, and then the nut is in threaded connection with the bolt till the gasket abuts against the shaft sleeve; the cross shaf
