我的翻譯 4 k$ e% j2 Q* Y( X 8 O) a1 S/ E8 { u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 9 H5 S4 V+ r- R# V# `
1。不要更換液壓油 - 而應該過濾。 6 U* r: x z" X0 K6 e2 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。 ' m4 @" A3 j$ M5 g+ t" p
2。消除顆粒污染以減少故障……& ]/ d% T3 B& E5 L: ^) S
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 B1 p! W+ y( \( _; r
3。 ……，延長油液的壽命。 5 t% d* ]& j K9 r
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。 4 }& V9 e! k v' y" j) D' A4。保持液壓油冷卻。 4 K) B8 E+ [- I5 T4 F- M
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。作者: 浪漫滿屋 時間: 2010-7-20 20:45
