用試管裝入新油和舊油，然后進(jìn)行外觀對(duì)比檢查，通過感官進(jìn)行判斷其污染程度。當(dāng)液壓系統(tǒng)中舊油液變成乳白色時(shí)，是油液中混入水分所致，必須分離水分并摻入新油調(diào)整黏度后才能繼續(xù)使用;當(dāng)舊油液呈透明狀但有小黑點(diǎn)時(shí)，是油液中混入異物所致，必須過濾后才能使用;液壓系統(tǒng)舊油液變成黑褐色并伴有暗惡臭時(shí)，是油液氧化所致，必須更換油液。 液壓油的黏度大小對(duì)液壓系統(tǒng)工作有何影響? 黏度是液壓油最重要的使用性能指標(biāo)之一，它合理與否，對(duì)液壓系統(tǒng)的平穩(wěn)性、工作可靠性和靈敏性、系統(tǒng)效率、功率消耗、氣蝕現(xiàn)象、溫升和磨損等都有顯著的影響。當(dāng)液壓系統(tǒng)液壓油黏度較高時(shí)，使液壓油的流動(dòng)阻力加大，流動(dòng)速度減慢，可能影響泵吸油不暢;當(dāng)液壓系統(tǒng)液壓油黏度較高時(shí)，由于磨擦加劇，油溫升高，而產(chǎn)生泄漏;倘若液壓油黏度偏低，必然加劇泄漏損失，并且會(huì)由于運(yùn)動(dòng)零件之間的油膜破裂，而導(dǎo)致零件的液壓系統(tǒng)磨損加快。
