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 4 ^5 d. V$ Z9 _# p7 l& F
1。不要更换液压油 - 而应该过滤。 3 L6 O! ]; M- R+ ]- U" C
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。
% i2 n1 t0 Q) I. P* {4 v& t2 c2。消除颗粒污染以减少故障……3 X2 |4 f* d/ M7 G+ ~0 ^2 g H
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。
6 `3 N& F ^- {. o. ?$ y" K4 {3。 ……，延长油液的寿命。
* r1 Y& A! |6 S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+ L9 V* O+ ?4。保持液压油冷却。 : ?+ B2 k [+ J8 ]. S
过高的工作温度加速了液压油的氧化速度，降低其使用寿命。油氧化过程中的副产品——涂料和沉淀物，可能会导致可靠性问题，如滑阀运动的粘滞和过滤器堵塞。 |
