Plastic pump shaft assembly machine with clamping mechanisms

Abstract

The invention provides a plastic pump shaft assembly machine with clamping mechanisms and belongs to the technical field of machines. The plastic pump shaft assembly machine with the clamping mechanisms comprises a rack and is characterized in that the rack is provided with an annular sliding groove; a plurality of sliding blocks are slidably arranged in the sliding groove and can cyclically movein the sliding groove; the sliding blocks are all provided with the clamping mechanisms used for fixing a spindle; the rack is further fixedly provided with a cylinder I used for driving the sliding blocks to move leftwards, a cylinder II used for driving the sliding blocks to move rightwards and a cylinder III used for driving the sliding blocks to move upwards; the cylinder I is located on the upper portion of the rack, the cylinder II is arranged on the lower portion of the rack and the cylinder III is located on the side, far away from the cylinder II, of the rack; and the rack is fixedlyprovided with a carrying rack I, and the two ends of the carrying rack I are both provided with conveying mechanisms I used for conveying left protective shells or right protective shells. The plasticpump shaft assembly machine with the clamping mechanisms has the characteristic of high assembly efficiency.

AI Technical Summary

Problems solved by technology

[0003] Problems caused by pump cavitation: The main reasons for pump cavitation are large pump inlet pipe resistance, more gas phase of the conveying medium, insufficient filling of the pump, and insufficient energy head at the pump inlet, etc.

Cavitation is the most harmful to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will cause damage to the plastic pump bearing and pump shaft.

[0004] The current plastic pump shaft material is made of silicon carbide or ceramics. These two materials are easy to break in the case of improper operation or when the pump shaft is locked, the pump shaft and the motor are not concentric, idling, dry hitting, etc.

[0005] Now with a new type of pump shaft, multiple parts are required to assemble, which will lead to inefficiency if assembled manually
