Cleaning multistage centrifugal pump repair work is an important part of the quality of cleaning equipment for maintenance quality. Use correct cleaning methods to improve quality, reduce cleaning costs, and one of the issues that must be considered for repairs.
Maintenance work, including mechanical external cleaning and cleaning parts cleaning, parts cleaning, because identification purposes can be divided into pre-assembly plating or bonded cover work to prepare for pre-cleaning, cleaning and cleaning parts.
In parts cleaning, coatings and adhesives cover the most demanding parts cleaning, cleaning quality is not high. The reason for this is usually caused by a failure of coating or adhesion, which greatly affects the mechanical life and assembly. Due to serious cleaning failures, a large number of important abrasive friction lubricants or plugging infiltration, due to dirt roads leading to early wear and accidental damage, there is not enough often happen in some maintenance work, must pay attention.
Wash with just a few singlestage centrifugal pumps. Describe the specific rationale to clear afterwards.
1) Scrape the inner and outer surfaces of the impeller and the seal ring and the ground and other objects in the orientation of scale and rust, and then blow with clean water or compressed air.
2) Join each shell to clean grease and rust on the upper surface.
3) Clean the sealed tube and check for flow tubes.
4) Clean the bearings and bearings, remove grease, and then wash the oil ring and oil gauge. Gasoline cleaning ball bearing applications.
5) Temporarily used for assembly of parts, should be cleaned and protected after oiling.
The basic principles of all cleaning and cleaning methods must fully consider the following basic requirements.
1) Cleaning is guaranteed to meet the requirements of the maintenance requirements, the different parts of the required cleaning degree are not the same. In assembly, cleaning requires less static fitting than non-mating part assembly, and accuracy is better than inaccurate fit fitting. The requirements for spraying, plating, surface bonding, and cleaning are very high. Depending on the requirements, different cleaning agents and cleaning methods must be used to ensure the required cleaning quality is taken.
2) To prevent corrosion of parts, precision parts do not allow any degree of corrosion. After cleaning the parts required for parking for a period of time, you should consider the rust and rust resistance of the cleaning fluid or consider other measures.
3) To ensure safe operation, prevent the body and cause fire or poison to pollute the environment.
4) Emphasizing economic efficiency and ensuring the above conditions, it is necessary to improve efficiency, reduce raw material costs, reduce equipment costs, and improve economic efficiency.
