style="text-indent:25px">液壓系統(tǒng)的常見故障：空穴現(xiàn)象?，F(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。原因：液壓油中總含有一定量的空氣，通常可溶解于油中，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)，溶解于油中的空氣分離出來，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。部位：吸油口及吸油管中低于大氣壓處，易產(chǎn)生氣穴；油液流經(jīng)節(jié)流口等狹小縫隙處時(shí)，由于速度的增加，使壓力下降，也會(huì)產(chǎn)生氣穴。危害：氣泡隨油液運(yùn)動(dòng)到高壓區(qū)，在高壓作用下迅速破裂，造成體積突然減小、周圍高壓油高速流過來補(bǔ)充，引起局部瞬間沖擊，壓力和溫度急劇升高并產(chǎn)生強(qiáng)烈的噪聲和振動(dòng)。措施：要正確設(shè)計(jì)液壓泵的結(jié)構(gòu)參數(shù)和泵的吸油管路，盡量避免油道狹窄和急彎，防止產(chǎn)生低壓區(qū)；合理選用機(jī)件材料，增加機(jī)械強(qiáng)度、提高表面質(zhì)量、提高抗腐蝕能力。標(biāo)準(zhǔn)伺服液壓系統(tǒng)液壓系統(tǒng)維護(hù)保養(yǎng)：定期沖洗油泵的進(jìn)口油濾。</p><div

style="text-indent:25px">按液壓泵組輸出流量特性，可將液壓泵站分為定量型和變量型兩種。若采用定量泵液壓泵站，要根據(jù)液壓系統(tǒng)對(duì)流量的需求，既可以配置單臺(tái)定量泵，也可配置多臺(tái)定量泵；若采用變量型液壓泵站，可按壓力-流量的調(diào)節(jié)特性再分為恒功率式、恒壓式、恒流量式、限壓式以及壓力切斷式，不同的輸出壓力和流量特性可適用于不同的主機(jī)工況和工作需求。在工程實(shí)際使用中，往往大多選擇壓力補(bǔ)償型變量泵供油，當(dāng)液壓系統(tǒng)達(dá)到既定壓力時(shí)，液壓油不是從溢流閥高壓溢流而出，而是通過減少泵的流量輸出方式以實(shí)現(xiàn)安全保護(hù)作用。</p><p style="text-indent:25px">液壓的影響因素有哪些？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。液壓系統(tǒng)的剛度大、精度高、響應(yīng)快。</p><div
