下面是四个快速提示，从中你可以以最快的速度了解每个液压系统最重要的组成部分——液压油的使用注意事项
) H$ C: z) l" `' v1。不要更换液压油 - 而应该过滤。
, x# H2 t* y! v2 r+ K2 e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。
# Q% [$ X7 ^' U4 Z. \# N: n! ~2。消除颗粒污染以减少故障……$ Y. {% m2 Y! t* {8 A2 k
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。 3 d( X* ]; b" B/ \
