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(tǒng)最重要的組成部分——液壓油的使用注意事項(xiàng) , W( `$ ~+ P; q5 P& A" U
1。不要更換液壓油 - 而應(yīng)該過濾。 * e2 ~0 ?% u6 N+ b( U w/ a) ]1 C
水或顆粒性質(zhì)的污染很少導(dǎo)致必須更換液壓油——除非污染已經(jīng)導(dǎo)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。 7 R; C1 `2 B* @3 f
2。消除顆粒污染以減少故障……% V. K6 r* m4 s
研究顯示,保持油液的潔凈度在ISO 4406 16/14/11標(biāo)準(zhǔn)下,相較于保持在標(biāo)準(zhǔn)24/22/19下,將導(dǎo)致兩次故障的間隔時間平均增加了10倍。這是根據(jù)一項(xiàng)為期三年的、關(guān)于117個移動和工業(yè)用液壓設(shè)備的研究所得出的結(jié)論,該研究用以確定油液的潔凈度和故障率之間的關(guān)系。 ( a9 i3 U! z6 l6 K/ Q2 o7 R$ L4 ~
3。 ……,延長油液的壽命。
: i5 S5 g5 H c* ?顆粒污染通過剝離添加劑和促進(jìn)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。 & u7 v* [( t" T5 U! |4 d
4。保持液壓油冷卻。
$ r: B; c1 x M U1 ]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(chǎn)品——涂料和沉淀物,可能會導(dǎo)致可靠性問題,如滑閥運(yùn)動的粘滯和過濾器堵塞。 |
