how to clean Centrifugal pump parts?

Cleaning is an important part of the repair work, cleaning quality has great influence on the quality of mechanical repair. Using the correct cleaning method to improve the quality and reduce cost, is one of the repair workers must consider the question. Repair job of cleaning including mechanical parts of external washing and cleaning, parts cleaning can be divided into the different aims and identified before cleaning, clean before assembly and parts before plating cover or bond up the cleaning work.

Pump parts cleaning, plating cover and binding parts of cleaning the most demanding, cleaning quality is not high. Often the cause of coating or bond failure, assembly and parts cleaning quality, had a great influence on the service life of mechanical. As cleaning is unqualified, in the important friction pair of abrasive or caused by dirt clogging oil duct machinery of early wear and accidental damage, in some formal often happens in the repair work is not enough, must be pay attention to.

The list of centrifugal pump for a cleaning. The specific clear after the basic principles in detail.

1) to the impeller and seal ring and bearing internal and external surface accumulated by the scale and rust, water or compressed air cleaning, blowing off again.

2) clean water pump shell of stored oil dirties and the jointing surface rust.

3) clean water seal tube and check whether the tube is clear.

4) clean the bearing and the bearing, remove oil dirties, and cleaning oil and oil level gauge, etc. Ball bearing application of gasoline cleaning.

5) temporarily not to the assembly of parts and components, should be greased protection after cleaning.

The basic principle of centrifugal pump cleaning for all cleaning method, must fully consider the following a few basic requirements.

1) ensure that meet the requirements of clean degree of parts, in the repair of the pump, a variety of different parts, the requirement of clean degree is not the same. In the assembly, with a clean requirements higher than that of the mating parts, with higher than static matching parts, precision is higher than the precision with parts. For surface spraying, plating, bonding, the cleaning requirements are very high. When cleaning must take according to different requirements, different cleaning agents and cleaning method, ensure the quality of the required cleaning. 

2) to prevent the corrosion of the parts, the precision parts are not allowed to have any degree of corrosion. When the water pump parts after cleaning to be parked for a period of time, should consider cleaning rust resistance or consider other rust prevention measures.

3) to ensure safe operation, to prevent fire or poison the body and cause pollution to the environment.
