AI Technical Summary

Technical Problem

Traditional centrifugal pump impeller disassembly methods are inefficient and easily damage the impeller. Furthermore, the puller is difficult to position and slippage occurs frequently, affecting disassembly efficiency and safety.

Method used

A centrifugal pump impeller disassembly tool was designed, which uses a threaded rod and a sleeve. The grippers are precisely centered and positioned by a stabilizing component, and slippage is prevented by a rubber pad and the stabilizing component, thus protecting the impeller surface.

Benefits of technology

It achieves precise centering and positioning of the impeller, prevents slippage, improves disassembly efficiency, reduces damage to other components, protects the impeller surface, and reduces the labor intensity of maintenance personnel.
