1。不要更換液壓油 - 而應(yīng)該過濾。 % r4 k+ R2 \: |4 a& j
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。
4 d4 @' E* T" x3 a2。消除顆粒污染以減少故障……
5 b1 W0 d1 e+ g% X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。 ( u# A9 J/ o2 t2 w+ H3 Z" ]
3。 ……,延長油液的壽命。
) i; J7 M- O1 I3 C% s2 V- e6 ?0 i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。
& B" m5 X8 \. j9 B H3 V W+ R# \4。保持液壓油冷卻。
' U# w, C; ~- D I5 H: b8 y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。 |
