D type centrifugal pump parts cleaning method to extend the service life of the right

How to clean the type D is important for the life of the water pump, centrifugal pump parts cleaning is an important part in the work, cleaning quality has great influence on the quality of mechanical repair. The correct cleaning methods to improve the quality of D type centrifugal water pump clean and reduce cost, is one of the repair workers must consider the question.

repair job of cleaning including mechanical external cleaning and parts cleaning. Clean parts for different purposes, can be divided into the identification before cleaning, cleaning, plating parts before assembly or bond before cleaning.

in parts cleaning, plating and bonded parts cleaning requirements, highest cleaning quality is not high. Is often the cause of coating or bond failure. While ZhuanPei cleaning quality of the parts, had a great influence on the mission of mechanical life. As cleaning is unqualified, in the important friction pair of abrasive, or because of dirt clogging oil duct, lead to mechanical early wear and accidental damage, in some informal often happens in the repair work, must be pay attention to.

detailed below D type centrifugal pump parts clean illustrate a few key points: 1)

Scrape off 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） Cleaning pump body of the jointing surface deposited oil dirties and rust.

       3） The cleaning water pipe and check the tube was clear.

       4） Cleaning oil and bearing, and clean out dirt, oil and oil level gauge, etc. Ball bearing application of gasoline cleaning.

       5） Temporarily not assembly of parts, components, should be greased protection after cleaning.

D type centrifugal pump all the cleaning method must give full consideration to the following a few basic requirements: 1)

Ensure to meet the requirements of the clean degree of parts. In repair, all kinds of different parts for clean degree is no longer the same assembly, with a cleaning requirement is higher than the mating parts: dynamic assemblies, higher than the static mating parts: precision is higher than the precision with parts. For surface spraying, plating, bonding, the cleaning requirements are very high. Cleaning is necessary according to different requirements, adopt different detergent cleaning method, ensure the quality of need cleaning.

       2） Prevent corrosion type D centrifugal pump parts. The precision parts are not allowed to have any degree of corrosion. When the parts to be parked for a period of time after cleaning, cleaning fluid rust resistance should be considered, or consider other rust prevention measures.

       3） Ensure the operation safety, prevent fire or harm anyone, and caused the pollution to the environment.

       4） Be particular about economic benefits. In guarantee under the condition of the above conditions, should be to improve efficacy, reduce the cost of raw materials, reduce the cost of equipment to improve the economic effect.
