According to the technical scheme, the pump impeller and the detacher are fixed through screws during operation, a large distance exists between the jack and the pump shaft due to the fact that the impeller has a certain distance on the pump shaft, and the relay connecting device is arranged between the telescopic rod of the jack and the pump shaft of the impeller.

According to the preferred technical scheme, the relay connecting device comprises a mandril base and a mandril welded on the mandril base. According to the preferred technical scheme, a round ball is welded on the ejector rod of the ejector rod. The round ball is in full contact with the arc concave surface at the top point of the pump shaft, so that the ejector rod is prevented from deviating.

According to the preferable technical scheme, the bottom of the top plate is provided with a guide pipe. The ball is aligned with the pump shaft through the guide pipe and the working hole at the bottom of the top plate, so that the stress of the pump shaft is balanced.

According to the preferable technical scheme, the top plate and the bottom plate are made of two channel steel, and the connecting support is made of a seamless steel pipe. The materials commonly used in factories are welded and connected, so that the cost is low, and the structure is simple and practical.

This neotype beneficial effect is: the material using structure is simple, the whole structure of the device is more stable, the fixing and dismounting effects of the hydraulic power whole vacuum pump impeller dismounting device are better, the dismounting impeller can save time and labor, and the working efficiency is improved.
