當(dāng)出現(xiàn)前一種故障時，應(yīng)先檢查上車工作油壓，不加大油門操縱伸縮手柄，觀察油壓表，若油壓上升，說明伸縮缸平衡閥阻尼孔堵塞，須拆下清洗并消除阻尼孔內(nèi)的堵塞物;若油壓不上升，但在加大油門時油壓卻能達到工作要求，則可確定是液壓泵出了故障。 </p> <p> 如果上面檢查都沒有問題，應(yīng)做單項檢查，若伸縮臂伸縮時出現(xiàn)抖動并發(fā)出響聲，首先，應(yīng)檢查伸縮臂與基本臂之間摩擦面的潤滑情況及滑塊磨損情況。必要時應(yīng)涂加黃油或更換新滑塊，并調(diào)整滑塊與伸縮臂之間的間隙。其次，檢查伸縮缸上的托輥滑輪是否良好，若無問題，再檢查伸縮缸伸縮時有無響聲、爬行或振動。再次，如果伸縮缸正常，再檢查伸縮缸上的平衡閥，若閥內(nèi)彈簧疲勞變形，也會使伸縮臂產(chǎn)生抖動及發(fā)出響聲，此時更換彈簧即可。

平衡閥是保證汽車起重機安全使用的重要元件。如果變幅缸或伸縮缸的活塞桿外伸動作正常，但當(dāng)多路閥處于中位時活塞桿有持續(xù)緩慢回縮現(xiàn)象時，一般可判定是平衡閥密封不可靠。假如在負(fù)重情況下，液壓缸活塞桿間歇機的維修工作有參考價回縮，并伴有“咔、咔”聲，則有兩種可能：一是液壓缸有桿腔有空氣，由于空氣的可壓縮性和彈性，導(dǎo)致平衡閥間歇性開啟；二是液壓缸無桿腔密封不良，壓力油通過活塞處泄漏到有桿腔中，逐漸積蓄，到一定的壓力時使平衡閥開啟。有時會遇到活塞桿不能回縮的情況，此時可重點檢查平衡閥控制油路上的阻尼小孔是否堵塞，柱塞是否卡死。如果小孔沒有堵，柱塞也不卡，則可將小孔適當(dāng)擴大些，以減小小孔的節(jié)流作用，補償因柱塞和閥孔磨損產(chǎn)生的內(nèi)泄漏，這樣才能產(chǎn)生足夠的壓力來推動柱塞，頂開單向閥，使無桿腔回油。單缸插銷的伸縮技術(shù)改變了以往油缸不能加內(nèi)部繩排的作業(yè)方式，拓展了起重機向更高工作高度發(fā)展的空間。嘉定區(qū)汽車起重機價格</p><p

溢流閥產(chǎn)生高頻噪聲是先導(dǎo)閥性能不穩(wěn)定所致，即先導(dǎo)閥前腔壓力的高頻振蕩引起空氣振動發(fā)出的噪聲。主要原因是：油液中混入空氣，在先導(dǎo)閥前腔內(nèi)形成氣穴引發(fā)高頻噪聲，應(yīng)及時排盡空氣;針閥在使用過程中因頻繁開啟而過度磨損，使先導(dǎo)流量不穩(wěn)定、壓力產(chǎn)生波動引發(fā)噪聲，應(yīng)及時修理或更換;先導(dǎo)閥因彈簧疲勞變形造成其調(diào)壓功能不穩(wěn)定，使壓力波動大引發(fā)噪聲，應(yīng)更換彈簧。 </p> <p> (3)液壓缸噪聲 </p> <p> 液壓缸中空氣未完全排盡，在高壓作用下產(chǎn)生氣穴會引發(fā)較大噪聲，須及時排盡空氣;缸頭油封過緊或活塞桿彎曲，在運動過程中也會因別勁產(chǎn)生噪聲，須及時更換油封或校直活塞桿。瓊海汽車吊廠家</p><p
