飞机液压系统油液的污染与控制

摘要

飞机液压系统油液污染是危及飞行安全的一个重要因素.针对液压系统油液污染所造成的液压泵、伺服阀等元件的失效问题,提出控制液压系统油液污染应从提高元件的耐污染度和降低油液的污染度着手,使两者达到合理平衡,以保证液压系统的工作可靠性和元件的使用寿命.%Oil pollution of aircraft hydraulic system endangers (light safety badly. Aimed at the component invalidation on hydraulic pump, servo valve and so on caused by hydraulic pollutant, the controlling principles were bring forward, that controlling pollutions should be based on the improvement of antifouling performance and the debasement of oil contamination level. And only when the two measures achieved balance, reliability of hydraulic system and service life of component could be ensured ultimately.
