style="text-indent:25px">液壓系統(tǒng)的空穴現(xiàn)象現(xiàn)象：如果液壓系統(tǒng)中滲入空氣，液體中的氣泡隨著液流運(yùn)動(dòng)到壓力較高的區(qū)域時(shí)，氣泡在較高壓力作用下將迅速破裂，從而引起局部液壓沖擊，造成噪聲和振動(dòng)。另外，由于氣泡破壞了液流的連續(xù)性，降低了油管的通油能力，造成流量和壓力的波動(dòng)，使液壓元件承受沖擊載荷，影響其使用壽命，遼寧液壓系統(tǒng)油泵安裝。原因：液壓油中總含有一定量的空氣，通?？扇芙庥谟椭?，也可以氣泡的形式混合于油中。當(dāng)壓力低于空氣分離壓力時(shí)，遼寧液壓系統(tǒng)油泵安裝，溶解于油中的空氣分離出來，遼寧液壓系統(tǒng)油泵安裝，形成氣泡；當(dāng)壓力降至油液的飽和蒸氣壓力以下時(shí)，油液會(huì)沸騰而產(chǎn)生大量氣泡。這些氣泡混雜于油液中形成不連續(xù)狀態(tài)，這種現(xiàn)象稱為空穴現(xiàn)象。液壓站以油箱的有效貯油量度及電機(jī)功率為主要技術(shù)參數(shù)。遼寧液壓系統(tǒng)油泵安裝</p><div
