style="text-indent:25px">污染物是液壓系統(tǒng)油液中對系統(tǒng)起危害作用的的物質(zhì)，它在油液中以不同的形態(tài)形式存在，根據(jù)其物理形態(tài)可分成：固態(tài)污染物、液態(tài)污染物、氣態(tài)污染物。固態(tài)污染物可分成硬質(zhì)污染物，有：金剛石、切削、硅沙、灰塵、磨損金屬和金屬氧化物；軟質(zhì)污染物有：添加劑、水的凝聚物、油料的分解物與聚合物和維修時帶入的棉絲、纖維。液態(tài)污染物通常是不符合系統(tǒng)要求的切槽油液、水、涂料和氯及其鹵化物等，通常我們難以去掉，所以在選擇液壓油時要選擇符合系統(tǒng)標(biāo)準(zhǔn)的液壓油，避免一些不必要的故障。</p><p style="text-indent:25px">液壓泵使用要注意液壓泵可以用支座或法蘭安裝，泵和原動機(jī)應(yīng)采用共同的基礎(chǔ)支座，法蘭和基礎(chǔ)都應(yīng)有足夠的剛性。特別注意:流量大于 (或等于)160L/min的柱塞泵，不宜安裝在油箱上。液壓泵和原動機(jī)輸出軸間應(yīng)采用彈性聯(lián)軸器連接，嚴(yán)禁在液壓泵軸上安裝帶輪或齒輪驅(qū)動液壓泵，若一定要用帶輪或齒輪與泵連接，則應(yīng)加一對支座來安裝帶輪或齒輪，該支座與泵軸的同軸度誤差應(yīng)不大于Φ0.05mm。吸油管要盡量短、直、大、厚，吸油管路一般需設(shè)置公稱流量不小于泵流量2倍的粗過濾器 (過濾精度一般為80～180μm)。液壓泵的泄油管應(yīng)直接接油箱，回油背壓應(yīng)不大于0.05MPa。油泵的吸油管口、回油管口均需在油箱較低油面200mm以下。特別注意在柱塞泵吸油管道上不允許安裝濾油器，吸油管道上的截止閥通徑應(yīng)比吸油管道通徑大一擋，吸油管道長L<2500mm，管道彎頭不多于兩個。液壓試驗臺采用多泵供壓，輸出流量更大。</p><div
