Pump valve fittings cleaning principle

Jun 05, 2018

Cleaning is an important part of maintenance work for pumps and other equipment. At the same time, cleaning quality has an important impact on the quality of equipment maintenance. In simple terms, the correct cleaning method can not only improve the cleaning effect of the valve components, but also reduce the cost and improve the overall use of the pump and other equipment. Then, in the maintenance work, how to clean the pump valve accessories?


In general, during the maintenance work, the cleaning work for the pump and valve parts mainly includes the cleaning before assembly and the cleaning of parts before plating or bonding. For example, in the cleaning of the parts of the pump, the cleaning requirements of the plating cover and the bonded parts are the highest. The low cleaning quality is often the cause of plating or bonding failure, and the cleaning quality of the parts assembly has a great influence on the service life of the machine.


Therefore, if the cleaning operation is not up to standard, it will inevitably adversely affect the use and operation of the equipment in the later period. In severe cases, it can lead to premature wear of the pump or accidental damage. Therefore, in the maintenance work, we must pay attention to this point. We should know that these different pump and valve accessories play an important role in the normal operation of the pump.


For cleaning operations, we need to meet several basic requirements: First, to ensure that the requirements for the cleanliness of the pump valve components are met. In the repair of the pump, different types of components have different requirements for cleaning. In the assembly, the cleaning requirements of the mating parts are higher than those of the non-matching parts, the dynamic mating parts are higher than the static mating parts, and the precision mating parts are higher than the non-precision mating parts. For the surface of sprayed, plated and bonded workpieces, the cleaning requirements are very high. When cleaning, according to different requirements, different cleaning agents and cleaning methods must be adopted to ensure the required cleaning quality.


In addition, during the cleaning, special care must be taken to avoid corrosion of the pump valve fittings, especially if the precision parts do not allow any degree of corrosion. When the pump valve accessories need to be stopped for a period of time after cleaning, the anti-rust ability of the cleaning liquid should be considered or other rust prevention measures should be considered.http://www.dmgcastings.com/
