1. Scraping the inner surface and the outer surface of impeller and seal ring and bearing place accumulation scale and rust, water or compressed air cleaning, blowing.
2. The shell joint surface cleaning up dirt and rust.
3. Cleaning the water seal 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. Do not carry parts assembly, after cleaning oil should be protected.
Basic principles for the cleaning of multistage centrifugal pumps:
1. To meet the requirements of parts cleaning degree, under repair, a variety of different 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 cleaning the parts to be asked for a period of time, should consider the rust proof ability of the cleaning fluid or consider other anti rust measures.
3. To ensure the safety of operation, to prevent fire or to poison the human body and cause pollution to the environment.
