Multi-stage centrifugal pump cleaning project
1. Scrape off the scale and rust accumulated on the inner and outer surfaces of the impeller, the seal ring, the bearing and other places, and then clean and blow it off with water or compressed air.
2. Clean the grease and rust accumulated on the joint surfaces of the shell.
3. Clean the water seal pipe and check whether the pipe is unblocked.
4. Clean the bushes and bearings, remove the grease, and then clean the oil ring and oil level gauge. The ball bearings should be cleaned with gasoline.
5. All parts and components not to be assembled temporarily should be protected with oil after cleaning.
Basic principles of multi-stage centrifugal pump cleaning
1. Ensure to meet the requirements for the cleanliness of the parts. In the repair, various parts have different requirements for cleanliness. In assembly, the cleaning requirements of mating parts are higher than non-matching parts, moving parts are higher than static mating 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 must be adopted according to different requirements
Method to ensure the required cleaning quality.
2. Prevent the corrosion of the parts, and no corrosion of any degree is allowed to the precision parts. 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. Ensure the safety of operation, prevent fire or poisoning the human body and cause pollution to the environment.
