The workers' energy is reduced during long-term assembly, which will cause position deviation and corresponding errors of the connection holes, resulting in low assembly efficiency. Therefore, those skilled in the art provide a multi-stage centrifugal pump processing and assembly equipment to solve the problems raised in the above background technology. Utility Model Content

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a multi-stage centrifugal pump processing and assembly equipment, which has the following beneficial effects:

[0014] Through the design, when the placement hole with the finished impeller rotates to the discharge port on the support plate, the second hydraulic rod on the upper part of the bracket drives the rubber pressure plate to press down, and the finished impeller at the corresponding discharge port is pressed down to the pump shaft that is positioned and plugged with the fixed sleeve for insertion.
