Manufacture of gear pump, gear motor, orbital motor and valves.
Cleaning is an important part of the repair work, and the quality of the cleaning has a great influence on the quality of the repair of the machine. Accurate cleaning of centrifugal pumps to improve cleaning quality and reduce costs is one of the issues that repair workers must consider. Cleaning in repair work, including mechanical external cleaning and parts cleaning, and parts cleaning, can be divided into pre-identification cleaning, pre-assembly cleaning, and part plating or pre-bonding pre-cleaning.
In the cleaning of parts of multi-stage centrifugal pumps and gear pumps, the cleaning requirements of plating and bonding parts are the highest, and the cleaning quality is not high. It is often the cause of coating or bonding failure, and the cleaning quality of parts assembly and the use of machinery. Life has a great impact. Because of the severe differences in cleaning, the infiltration of large amounts of abrasives in important friction pairs or the clogging of lubricating oil passages due to dirt causes early wear and accidental damage of machinery, in some irregular repair work. Occurs, it must be noted.
The following is a summary of the cleaning methods for several parts of a multi-stage centrifugal pump and notes:
1) Scrape off the scale and rust accumulated on the inner and outer surfaces of the impeller, seal ring and bearing, etc., then wash or blow off with water or compressed air.
2) Clean the accumulated grease and rust on each joint surface of the water pump housing.
3) Clean the water seal tube and check if the tube is clear.
4) Clean the bearing bush and bearings, remove grease, and then clean the oil ring and oil level gauge. Ball bearings are used for gasoline cleaning.
5) Zero parts and parts that are not assembled for the time being, should be oiled after cleaning.
