style="text-indent:25px">液壓系統(tǒng)的常見故障：流量損失。在液壓系統(tǒng)中，各被壓元件都有相對運動的表面，如液壓缸內(nèi)表面和活塞外表面，因為要有相對運動，所以它們之間都有一定的間隙。如果間隙的一邊為高壓油，另一邊為低壓油，則高壓油就會經(jīng)間隙流向低壓區(qū)從而造成泄漏。同時，由于液壓元件密封不完善，一部分油液也會向外部泄漏。這種泄漏造成的實際流量有所減少，這就是我們所說的流量損失。流量損失影響運動速度，而泄漏又是難以避免的，所以在液壓系統(tǒng)中泵的額定流量要略大于系統(tǒng)工作時所需的較大流量。通常也可以用系統(tǒng)工作所需的較大流量乘以一個1.1~1.3的系數(shù)來估算。</p><p style="text-indent:25px">液壓泵站的驅(qū)動方式：①電動型——此類液壓泵站以電動機(jī)作為原動機(jī)，適宜有穩(wěn)定電力供應(yīng)的固定式機(jī)械設(shè)備所采用，工作時噪聲較低，因此應(yīng)用為普遍；②機(jī)動型——此類液壓泵站以柴油機(jī)或汽油機(jī)為原動機(jī)，無需電源，便于無電力供應(yīng)或電路短缺的偏遠(yuǎn)地區(qū)以及野外作業(yè)的各類施工設(shè)備所使用，但工作時噪聲較大，使用率偏低；③手動型——此類液壓泵站以人力操縱為主，實際可看作是一種手搖泵，盡管其工作效率較低，但可通過簡單配管即可向小行程液壓缸予以供油，因此常與小型壓力機(jī)、試驗機(jī)、彎管機(jī)和搶險救援拆破器具、液壓剪等手動機(jī)具和設(shè)備配套使用，并可作為機(jī)動車輛的便攜式移動源。液壓泵站的液壓油的油溫，應(yīng)小于65℃。</p><div

style="text-indent:25px">液壓系統(tǒng)在分析和設(shè)計實際任務(wù)時，一般采用方框圖顯示設(shè)備中實際運行狀況。空心箭頭表示信號流，而實心箭頭則表示能量流。基本液壓回路中的動作順序—控制元件（二位四通換向閥）的換向和彈簧復(fù)位、執(zhí)行元件（雙作用液壓缸）的伸出和回縮以及溢流閥的開啟和關(guān)閉。對于執(zhí)行元件和控制元件，演示文稿都是基于相應(yīng)回路圖符號，這也為介紹回路圖符號作了準(zhǔn)備。根據(jù)系統(tǒng)工作原理，您可對所有回路依次進(jìn)行編號。如果第1個執(zhí)行元件編號為0，則與其相關(guān)的控制元件標(biāo)識符則為1。如果與執(zhí)行元件伸出相對應(yīng)的元件標(biāo)識符為偶數(shù)，則與執(zhí)行元件回縮相對應(yīng)的元件標(biāo)識符則為奇數(shù)。不僅應(yīng)對液壓回路進(jìn)行編號，也應(yīng)對實際設(shè)備進(jìn)行編號，以便發(fā)現(xiàn)系統(tǒng)故障。液壓系統(tǒng)由于受生產(chǎn)計劃和技術(shù)條件的制約，因此障診斷人員需要準(zhǔn)確，高效地診斷出液壓設(shè)備的故障。液壓試驗設(shè)備供應(yīng)</p><p
