style="text-indent:25px">污染物是液壓系統(tǒng)油液中對(duì)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(shí)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(shí)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
