style="font-size:20px;">液壓缸匍匐。主要原因有兩個(gè)：一是剛修過的油缸或放置時(shí)刻較長的油缸，開始使用時(shí)出現(xiàn)匍匐，有時(shí)還可在液壓油箱見到泡沫狀的液壓油溢出，這是因?yàn)轶w系中混入了空氣，掃除空氣即可。二是機(jī)械阻力過大，須拆檢缸筒、活寒及活塞桿。</span></p> <p> <span style="font-size:20px;">油缸推力缺乏，有負(fù)荷時(shí)油缸不動(dòng)作?？勺鋈缦聦?shí)驗(yàn)：在油缸空負(fù)荷時(shí)操作換向閥，假如油缸能夠自山彈性，且有時(shí)伸出和縮回的速度比正常時(shí)快，能夠斷定是油缸毛病。因油缸內(nèi)進(jìn)入雜質(zhì)或鐵屑將活塞上的油封及支承環(huán)嚴(yán)峻損壞，使油缸的有桿腔和無桿腔連通，構(gòu)成了差動(dòng)回路。</span></p> <p> <span style="font-size:20px;">漏油, 液壓缸除因銜接油管和油管O型圈損壞而導(dǎo)致外部漏油外，由缸頭上活塞桿密封失效導(dǎo)致內(nèi)部漏油也是對(duì)比多見的毛病。</span></p> <p> <span style="font-size:20px;">拉缸，液壓缸拉缸主要是因?yàn)榛钊透淄仓g的耐磨環(huán)磨損過度后使活塞和缸筒直接觸摸，活塞硬度大于缸筒硬度，活塞就會(huì)切削缸筒而導(dǎo)致拉缸。拉缸后，液壓缸提高和下降均無力，拉缸嚴(yán)峻的，缸筒即作廢。</span></p> <p> <span style="font-size:20px;">變形，液壓缸變形主要是液壓缸因?yàn)槭艿酵饬ε鰮艋蚴茌d過重。</span></p> <p> <span style="font-size:20px;">液壓缸活塞桿損壞，如活塞桿被外物刮花或活塞桿外表與空心腔相通。上。先退出控制系統(tǒng)程序，后堵截電源。</span></p> <div id="mg0g2u4"
