Basic principles of cleaning maintenance of multistage pump
1. Ensure that the requirements for the cleanliness of the parts are met. In the repair, various parts have different requirements for cleanliness. In assembly, the cleaning requirements of matching parts are higher than non-matching parts, moving matching parts are higher than static matching parts, and precision matching parts are higher than non-precision matching parts. For the surface of sprayed, plated, and bonded workpieces, the cleaning requirements are very high. When cleaning, different cleaning agents and cleaning methods must be adopted according to different requirements to ensure the required cleaning quality.
2. Prevent corrosion of parts, and no corrosion of precision parts is allowed. When the parts need to be parked for a period of time after cleaning, the anti-rust ability of the cleaning fluid or other anti-rust measures should be considered.
3. to ensure the safety of operation, to prevent fire or poisoning the human body and causing pollution to the environment.
