# D0 g! l( G, O+ _下面是四個(gè)快速提示,從中你可以以最快的速度了解每個(gè)液壓系統(tǒng)最重要的組成部分——液壓油的使用注意事項(xiàng) 7 A4 S) J$ v; U0 K- l+ Z4 J) N
1。不要更換液壓油 - 而應(yīng)該過濾。 / f% T; f9 d4 \- v
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。

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(shí)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(gè)移動(dòng)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。

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。
