% K9 U2 W* q7 g6 t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
3 N) \+ E# o5 g, P1。不要更换液压油 - 而应该过滤。
9 s4 m+ S; K+ Q- U: a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。 : V) P% s2 K0 ^0 b0 w
2。消除颗粒污染以减少故障……/ _2 X. L1 W3 g D
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。 9 J9 R0 Q* o; r* d$ t6 }
3。 ……，延长油液的寿命。 : w5 k0 A# g# [& Y
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。 8 }& ]1 Y/ t8 m4 u2 t5 K' }
4。保持液压油冷却。
5 H0 d- E# h, {# \ z A7 H$ _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。 |
