Precautions for dismantling corrosion-resistant centrifugal pumps

　　When disassembling or installing nuts for corrosion-resistant centrifugal pumps, a suitable size solid wrench should be used.

　　When using a wrench, the direction of force application should be perpendicular to the wrench handle, usually using tension instead of pushing.

　　Before maintenance, the mechanical personnel or construction technicians of the maintenance unit should be responsible for preparing the maintenance plan and providing technical disclosure of the maintenance plan to all personnel participating in the maintenance.

　　The destructive disassembly method refers to the disassembly measures that must be taken to preserve the main components and damage the auxiliary components when fixed connections such as welding, riveting, sealing connections, interference connections, etc., or when the shaft and sleeve are locked together, the key shaft is twisted, deformed, and severely corroded.
