Cleaning parts of water supply equipment is a crucial step in the repair process, with the quality of cleaning significantly affecting the mechanical repair. Employing the correct cleaning methods to enhance cleaning quality and reduce costs is one of the key considerations for repair workers. Cleaning during repairs includes both external mechanical cleaning and part cleaning, which can be further divided into pre-inspection cleaning, pre-assembly cleaning, and cleaning for coating or bonding preparation. In the cleaning of pump parts, the requirement for cleaning coated and bonded components is often insufficient in quality, often leading to failures in coatings or bonding. Moreover, the cleaning quality of assembled parts significantly impacts the mechanical lifespan. Due to severely inadequate cleaning, the infiltration of large amounts of abrasive material or blockage of lubrication channels by debris can lead to premature wear and accidental damage in critical friction pairs, which occasionally occurs in less正规 repair work and must be addressed.
Here are several components of water supply equipment to be cleaned. The specific cleaning principles will be detailed later.
Scrape away scale and rust accumulated on the inner and outer surfaces of the impeller, as well as the seals and bearings, and then clean and blow them clean with water or compressed air.
Clean the oil and rust accumulated on the joint surfaces of the cleaning pump casing.
3. Clean the water seal pipe and check if the pipe is clear.
4. Clean the shaft sleeves and bearings, removing grease, then wash the oil rings and oil level gauges. Ball bearings should be cleaned with gasoline.
5. Unassembled parts should be oiled for protection after cleaning.
The fundamental principles for cleaning water supply equipment require that all cleaning methods take into account the following basic requirements.
1. Ensuring compliance with the cleanliness requirements for parts, during pump repairs, different components have varying levels of cleanliness standards. In assembly, the cleanliness requirements for mating parts are higher than those for non-mating parts, dynamic mating parts exceed static mating parts, and precision mating parts surpass non-precision mating parts. For surfaces that are spray-coated, plated, or bonded, the cleanliness standards are particularly high. It is essential to use different cleaning agents and methods based on the specific requirements to ensure the required cleaning quality.
To prevent corrosion of parts, there should be no degree of corrosion allowed on precision components. When the pump parts are cleaned and need to be stored for a period, consider the rust prevention capabilities of the cleaning fluid or consider other rust prevention measures.
Ensure operational safety to prevent fires, poisoning of humans, and environmental pollution.
