style="text-indent:25px">若泵無(wú)故障則利用故障診斷回路檢測(cè)b點(diǎn)壓力變化情況。若點(diǎn)工作壓力能超過(guò)8.0Mpa并上升至所需高壓值，則說(shuō)明系統(tǒng)主溢流閥工作正常，需繼續(xù)檢測(cè)。若溢流閥無(wú)故障，則通過(guò)檢測(cè)點(diǎn)壓力變化情況即可判斷出是否換向閥或比例閥故障。通過(guò)檢測(cè)故障原因是葉片泵內(nèi)漏嚴(yán)重所引起。拆卸泵后方知，葉片泵定子由于滑潤(rùn)不良造成異常磨損，引起內(nèi)漏增大，使系統(tǒng)壓力提不高，進(jìn)一步發(fā)現(xiàn)是由于水冷系統(tǒng)的水漏入油中造成油乳化而失去潤(rùn)滑作用引起的。一個(gè)液壓系統(tǒng)的好壞不僅取決于系統(tǒng)設(shè)計(jì)的合理性和系統(tǒng)元件性能的的優(yōu)劣，還因系統(tǒng)的污染防護(hù)和處理，系統(tǒng)的污染直接影響液壓系統(tǒng)工作的可靠性和元件的使用壽命，據(jù)統(tǒng)計(jì)，國(guó)內(nèi)外的的液壓系統(tǒng)故障大約有70%是由于污染引起的。</p><p style="text-indent:25px">液壓缸零件材料如果制造液壓缸的材料具有較好的強(qiáng)度、韌性及抗腐蝕性，則其抗氣蝕能力較好;否則易發(fā)生氣蝕。另外材料組織的均勻度對(duì)氣蝕產(chǎn)生的影響也較大，材料組織越不均勻，在其強(qiáng)度薄弱處及抗腐蝕性低的地方就容易產(chǎn)生氣蝕。液壓油質(zhì)量液壓油質(zhì)量的好壞，是液壓缸是否產(chǎn)生氣蝕的一個(gè)重要因素。液壓油在工作中不可避免地與閥門、管路等發(fā)生沖擊，如果液壓油的抗泡沫性差，就很容易產(chǎn)生泡沫，從而導(dǎo)致液壓缸等部位產(chǎn)生氣蝕。若液壓油壓力變化頻率過(guò)快、過(guò)高，也將促使氣泡的形成，并加速氣泡的破裂速度。比如液壓缸進(jìn)、回油口處，由于壓力變化頻率相對(duì)較高，氣蝕的程度也相對(duì)高于其他部位。制造及維修液壓缸裝配或維修質(zhì)量對(duì)其氣蝕的影響也不可小視。如果在裝配或維修時(shí)未對(duì)液壓系統(tǒng)充分排氣，將導(dǎo)致系統(tǒng)中存在氣體，在高溫、高壓的作用下，液壓缸將產(chǎn)生氣蝕。液壓油是液壓系統(tǒng)中傳遞能量的工作介質(zhì)。</p><div
