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 $ E2 d7 n+ [7 t+ D8 a0 B6 X4 L
1。不要更換液壓油 - 而應該過濾。 % B# g i- W7 t; |
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。
. S, k8 L( c, O. p/ C7 k2。消除顆粒污染以減少故障……
7 q$ l8 B+ o: o5 o" K9 N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。 7 _0 Z1 Y# W& V; j) }
3。 ……，延長油液的壽命。 4 U, b0 ?, Y3 `# l H j/ X
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。 _1 |; O+ O- g
4。保持液壓油冷卻。
4 s4 M/ E: {0 \4 t' o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。 |
