下面是四個快速提示，從中你可以以最快的速度了解每個液壓系統最重要的組成部分——液壓油的使用注意事項 " O# A& J: O( K" Q
1。不要更換液壓油 - 而應該過濾。 # k" U+ ~" s$ f4 d; x, @9 G
水或顆粒性質的污染很少導致必須更換液壓油——除非污染已經導致添加劑耗盡或使原本的液壓油降解。這些污染物可以通過過濾的方式從液壓油中去除。 ; m' b0 z, M# I" U8 v) J, ~6 ^, h
2。消除顆粒污染以減少故障……1 e- e9 P) \; Y
研究顯示，保持油液的潔凈度在ISO 4406 16/14/11標準下，相較于保持在標準24/22/19下，將導致兩次故障的間隔時間平均增加了10倍。這是根據一項為期三年的、關于117個移動和工業用液壓設備的研究所得出的結論，該研究用以確定油液的潔凈度和故障率之間的關系。 2 |; o8 h$ {& h( b% O$ U+ ^
3。 ……，延長油液的壽命。
! o0 N" D# z/ U+ B! e' U顆粒污染通過剝離添加劑和促進氧化降低了液壓油的使用壽命。添加劑附著在顆粒上，或者被過濾器濾除或沉積在容器的底部。由于顆粒摩擦所造成的金屬磨損是液壓油氧化的催化劑。 # }7 V5 S/ \ \
4。保持液壓油冷卻。 9 s% ^# p4 B. Q# `! K
過高的工作溫度加速了液壓油的氧化速度，降低其使用壽命。油氧化過程中的副產品——涂料和沉淀物，可能會導致可靠性問題，如滑閥運動的粘滯和過濾器堵塞。 |
