The maintenance work of cleaning centrifugal pumps is an important component that has a significant impact on the quality of cleaning equipment. One of the issues that must be considered in maintenance is to use the correct cleaning methods, improve quality, and reduce cleaning costs.
Maintenance work includes mechanical external cleaning and cleaning of parts, as the purpose of identification can be divided into pre assembly plating or bonded cover preparation, pre cleaning, and cleaning of parts.
The cleaning quality is not high in the most demanding parts cleaning, coating and adhesive coverage. The reason is usually caused by coating or bonding failures, and the quality of cleaning greatly affects the mechanical life and assembly. Due to serious cleaning malfunctions, a large amount of important abrasive friction lubricants or blockage infiltration, early wear and accidental damage to parts caused by dirt roads, are there enough frequent occurrences in some maintenance work that must be paid attention to.
Just a few single-stage centrifugal pumps for cleaning. Describe specific basic principles to clear afterwards.
1) Scrape the inner and outer surfaces of the impeller, sealing ring, floor, and other objects with accumulated scale and rust, and then blow with clean water or compressed air.
2) Join each shell to clean the accumulated grease and rust on the upper surface.
3) Clean the sealing tube and check if there is a flow tube.
4) Clean the bearings and bearings, remove grease, and then clean the oil ring and oil gauge. Application of gasoline cleaning ball bearings.
5) Temporarily used for component assembly, should be cleaned and protected before oiling.
The basic principles of all cleaning methods must fully consider the following basic requirements.
1) The required level of cleanliness for parts that meet the maintenance requirements varies depending on the specific parts. In assembly and cleaning, moving parts have higher static fitting and accuracy than non precise fitting requirements for non fitting parts assembly. The requirements for spraying, electroplating, surface bonding, and cleaning are very high. Depending on the requirements, different cleaning agents and methods must be used to ensure the required cleaning quality.
2) To prevent corrosion of parts, precision parts do not allow any degree of corrosion. After cleaning the parts needed for parking for a period of time, you should consider the rust removal and rust prevention ability of the cleaning solution or consider other measures.
3) To ensure safe operation and prevent the body from catching fire or contaminating the environment with toxic substances.
4) When emphasizing economic efficiency and ensuring the above conditions, it is necessary to improve efficiency, reduce raw material costs, lower equipment costs, and improve economic benefits as the premise.
