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 5 p( c# m" j% U4 ?8 Y6 P1 [
1。不要更换液压油 - 而应该过滤。 ) m7 z5 l; z# o; c* ^& k. W
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。
; t$ ~! T7 E9 ]2。消除颗粒污染以减少故障……
, K c( M0 @; Z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。
0 @2 i8 \+ D; B) |* Z3。 ……，延长油液的寿命。 + W4 L' ]- r) L0 P- K
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。
# l S5 C5 u, a4。保持液压油冷却。
, L0 `: h- f3 L7 g9 N& ?1 i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。 |
