What is particulate cleanliness ?

Cleanliness refers to the degree to which parts, assemblies and specific parts of a machine are contaminated with impurities, indicating the quality, size and quantity of foreign particles collected from specific characteristic parts by predetermined methods. Specified parts refer to characteristic parts that endanger product reliability, impurities Including all impurities present in product design, manufacturing, transportation, use and maintenance, these impurities exist in themselves, external mergers and system generation, mainly used in auto parts, aero-engines, electronic components and other components.


Detection purpose:

The purpose of ensuring cleanliness is to achieve a specific service life of the product without shortening the service life of the product due to contamination during manufacturing, use and maintenance. By detecting the degree of cleanliness and its limits, damage caused by particle wear can be greatly reduced and improved. The service life and reliability of the whole machine can reduce the damage to the whole machine, such as: the filter is blocked, the circuit flow is reduced, the sealing material and diaphragm are abnormal, worn, and the amount of fouling is large, resulting in unreliable operation and unreliable operation of the electromagnetic switch valve. Or burn, etc., with special meaning.
