Description

Technical Field

[0001] The utility model relates to a multi-stage pump balance plate disassembling device, belonging to the technical field of multi-stage pump repair tools. Background Art

[0002] Multistage pumps are widely used in production due to their advantages such as high head. When the multistage centrifugal pump is running, there is a gap between the balance ring and the balance disk, and a layer of water film is between the two to prevent dry grinding between the balance ring and the balance disk. When the multistage pump malfunctions, the water film will be lost. At this time, the balance disk is in direct contact with the balance ring. Furthermore, the friction between the two will overheat, forming adhesion, causing multistage pump failure.

[0003] When repairing a faulty multi-stage pump, the balance disc and the balance ring need to be removed from the rotating shaft for replacement. However, the current disassembly methods of the multi-stage pump are single, mostly relying on manual holding tools for violent disassembly, or disassembly using machine tools after the pump body is disassembled. The above disassembly methods have cumbersome operating steps and high manual labor intensity, and the violent disassembly operation force is uncontrollable, which is easy to damage other related components; this disassembly method reduces the maintenance efficiency of the multi-stage pump.
