Regarding the maintenance and cleaning of submersible electric pumps, it has always been one of the key points of daily maintenance. Many pumps are prone to blockage and reduced flow under long-term working conditions, so regular cleaning of accessories is an important component of maintenance work. Cleaning has a significant impact on the quality of machine repairs. In order to improve cleaning quality and reduce costs, the correct cleaning method is one of the ethical issues that maintenance personnel must consider.
In the cleaning of accessories, the cleaning requirements for impellers and water outlets are high, and the cleaning quality is not high. The cleaning quality of accessory assembly has a great impact on the service life of the machinery. Due to severe cleaning failure, a large amount of abrasive infiltrates into important friction, or causes early mechanical wear and accidental damage due to dirt blocking lubricating oil channels. This often occurs in some irregular maintenance work and must be taken seriously. Below, the editor will introduce the method of cleaning submersible electric pump accessories.
Preparation tools: scraper, water, cloth, gasoline
Specific method:
1. Scrape off the scale accumulated on the outer surface of the impeller, sealing ring, and bearings, and then clean and blow it clean with water or compressed air.
2. Clean the accumulated oil and rust on the joint surfaces of the shell.
3. Clean the water seal pipe and check if the inside of the pipe is unobstructed.
4. Clean the bearing shell and bearings, remove oil stains, and then clean the oil ring and oil level gauge. Ball bearings should be cleaned with gasoline.
5. Parts and components that are temporarily not being assembled should be coated with oil for protection after cleaning.
The basic principle of cleaning is that all cleaning methods must fully consider the following basic requirements:
1.In order to ensure that the cleanliness requirements of the accessories are met, the cleanliness requirements for different accessories during repair are different.
During assembly, the cleaning requirements for accessories are higher than those for non accessories, dynamic accessories are higher than static accessories, and precision accessories are higher than non precision accessories. The cleaning requirements for the impeller, guide vanes, and outlet are very high. When cleaning, different cleaning agents and methods must be used according to different requirements to ensure the required cleaning quality.
2. To prevent corrosion of accessories, no degree of corrosion is allowed on precision accessories.
When the accessories need to be parked for a period of time after cleaning, the anti rust ability of the cleaning solution or other anti rust measures should be considered.
3. Ensure operational safety, prevent fires or harm to human health, and prevent environmental pollution.
4. Emphasis should be placed on economic benefits.
While ensuring the above conditions, the premise of improving efficiency, reducing raw material costs, and lowering equipment costs should be taken to enhance economic benefits.
The above is the method and process for cleaning accessories of submersible electric pumps. Regular and effective cleaning of explosion-proof submersible electric pump accessories can improve the service life of chemical pumps and effectively enhance work efficiency.
