When repairing vacuum pumps, especially in environments where conditions are not ideal, maintenance personnel from oil-free vacuum pump manufacturers must make every effort to ensure the cleanliness of the equipment. Additionally, oil-free vacuum pump manufacturers must select appropriate cleaning agents and strictly avoid using alkaline cleaning agents to prevent corrosion and rusting of components, particularly precision parts. Furthermore, aluminum and copper components should not be cleaned together in alkaline cleaning agents, and rubber components should not be cleaned together with steel components in gasoline, diesel, or acidic/alkaline cleaning agents.

During the maintenance of oil-free vacuum pumps, if manufacturers fail to thoroughly clean impurities from component surfaces or use improper cleaning methods, it can lead to component wear and corrosion damage, severely affecting maintenance quality and the service life of the vacuum pump after repair.
