* M' g1 @# A. g* ~9 y8 ?4 N1。不要更换液压油 - 而应该过滤。
. @. J3 p' w. p. f. Y# ^2 C/ Z+ }水或颗粒性质的污染很少导致必须更换液压油——除非污染已经导致添加剂耗尽或使原本的液压油降解。这些污染物可以通过过滤的方式从液压油中去除。

+ c6 M5 S' {' t研究显示，保持油液的洁净度在ISO 4406 16/14/11标准下，相较于保持在标准24/22/19下，将导致两次故障的间隔时间平均增加了10倍。这是根据一项为期三年的、关于117个移动和工业用液压设备的研究所得出的结论，该研究用以确定油液的洁净度和故障率之间的关系。

颗粒污染通过剥离添加剂和促进氧化降低了液压油的使用寿命。添加剂附着在颗粒上，或者被过滤器滤除或沉积在容器的底部。由于颗粒摩擦所造成的金属磨损是液压油氧化的催化剂。 - @# `( D% U5 B9 w
