七十年代以来,国外对工作油的污染及其对元件可靠性的关系就进行了深入研究。在我国,研究、制造、使用液压的实践中,也发现了工作油污染对液压元件或液压系统带来恶劣影响。许多生产厂努力创造条件搞净化装配,严格控制元件的内部清洁度,这仅考虑了问题的一个方面,因为工作油的污染仍能使内部清洁度很好的元件被污染,影响元件的工作可靠性和寿命等。本文就液压 Since the seventies, foreign countries have conducted in-depth research on the pollution of working oil and its relationship with component reliability. In our country, the research, manufacture and use of hydraulic pressure have also found that the working oil pollution has a bad influence on the hydraulic components or the hydraulic system. Many manufacturers strive to create the conditions for clean assembly and strictly control the internal cleanliness of the components. This only takes into account one aspect of the problem because the contamination of the working oil can still contaminate the components with good internal cleanliness and affect the reliability of the components Sex and life expectancy.
