* I9 w- y( q" }0 r. z( q: T& P1。不要更换液压油 - 而应该过滤。 , |9 f" t7 p6 S' @) j
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。 ; I# J$ Q B4 x
2。消除颗粒污染以减少故障……
! ^2 D. x- `4 Z P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。
+ P7 S% z; u# I( ]3 S" n3。 ……，延长油液的寿命。 7 M9 H9 d! T3 `4 n+ b" L
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。
6 Z3 o+ |& g! a) A4。保持液压油冷却。
! o- u( g( g( _% m, x5 V: ~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。 |
