style="text-indent:25px">密封件過(guò)早變質(zhì)可能是由多種因素引起的，一個(gè)重要因素是油溫過(guò)高。溫度每升高10℃則密封件壽命就會(huì)減半，所以應(yīng)合理設(shè)計(jì)高效液壓系統(tǒng)或設(shè)置強(qiáng)制冷卻裝置，使較佳油液溫度保持在65℃以下；工程機(jī)械不許超過(guò)80℃；另一個(gè)因素可能是使用的油液與密封材料的相容性問(wèn)題，應(yīng)按使用說(shuō)明書(shū)或有關(guān)手冊(cè)選用液壓油和密封件的型式和材質(zhì)，以解決相容性問(wèn)題，延長(zhǎng)密封件的使用壽命。有一點(diǎn)機(jī)械常識(shí)的人都知道，能量會(huì)互相轉(zhuǎn)換的，而把這個(gè)知識(shí)運(yùn)用到液壓系統(tǒng)上解釋液壓系統(tǒng)的功率損失是較好不過(guò)了，液壓系統(tǒng)功率一方面會(huì)造成能量上的損失，使系統(tǒng)的總效率下降，另一方面，損失掉的這一部分能量將會(huì)轉(zhuǎn)變成熱能，使液壓油的溫度升高，油液變質(zhì)，導(dǎo)致液壓設(shè)備出現(xiàn)故障。因此，設(shè)計(jì)液壓系統(tǒng)時(shí)，在滿(mǎn)足使用要求的前提下，還應(yīng)充分考慮降低系統(tǒng)的功率損失。液壓源含有液壓泵、電動(dòng)機(jī)和液壓輔助元件。</p><div
