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 5 n( k& j6 x; `- ]$ W
1。不要更換液壓油 - 而應該過濾。
0 }; {5 a4 D7 e) R! t- D% O. b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。
( a5 x3 L4 [! b1 c. |+ a% x2。消除顆粒污染以減少故障……- l- u& q4 ?8 o# \) U
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。
+ |" @0 U$ i! h" Y$ e3。 ……，延長油液的壽命。 # q* U: H0 t n" q% I& e- J
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。 ) m0 s: `) M# n/ ]
4。保持液壓油冷卻。 / K$ N3 Q4 q# z' S: \! U5 @7 X
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。 |
