Several parts of the centrifugal pump are listed. After the specific removal of the basic principles in detail:
1.Scraping the inner surface and the outer surface of the sealing ring and the impeller and bearings and other premises accumulation scale and rust, water or compressed air cleaning, blowing.
2.Cleaning pump shell the joint surface on the accumulation of grease and rust.
3.Cleaning water sealing pipe and check the pipe is smooth.
4.Bearing and bearing cleaning, remove grease, and cleaning of oil ring and oil level gauge etc.. Ball bearing application gasoline cleaning.
5.Temporary not zero parts assembly, after cleaning oil should be protected.
The basic principles for the cleaning of centrifugal pumps for all cleaning methods must be fully considered the following basic requirements:
1. To meet the requirements of parts cleaning, in the repair of pump, various parts, is not the same degree of cleanliness. In the assembly, the cleaning requirements of the complex parts are higher than the non mating parts, and the moving parts are higher than the static parts. For spray, plating, bonding of the workpiece surface, the cleaning requirements are very high. Cleaning must be based on different requirements, to take different cleaning agents and cleaning methods, to ensure that the required cleaning quality.
2. To prevent the corrosion of parts, the precision parts are not allowed to have any degree of corrosion. When the pump parts need to be parked for a period of time when asked, should consider the rust proof ability of the cleaning fluid or consider other rust preventive measures.
3. To ensure the safety of operation, to prevent fire or to poison the human body and cause pollution to the environment.
