平衡閥是保證汽車起重機(jī)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(dòng)作正常，但當(dāng)多路閥處于中位時(shí)活塞桿有持續(xù)緩慢回縮現(xiàn)象時(shí)，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(jī)的維修工作有參考價(jià)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(kāi)啟；二是液壓缸無(wú)桿腔密封不良，壓力油通過(guò)活塞處泄漏到有桿腔中，逐漸積蓄，到一定的壓力時(shí)使平衡閥開(kāi)啟。有時(shí)會(huì)遇到活塞桿不能回縮的情況，此時(shí)可重點(diǎn)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(méi)有堵，柱塞也不卡，則可將小孔適當(dāng)擴(kuò)大些，以減小小孔的節(jié)流作用，補(bǔ)償因柱塞和閥孔磨損產(chǎn)生的內(nèi)泄漏，澄邁汽車吊怎么樣，澄邁汽車吊怎么樣，這樣才能產(chǎn)生足夠的壓力來(lái)推動(dòng)柱塞，頂開(kāi)單向閥，使無(wú)桿腔回油，澄邁汽車吊怎么樣。汽車起重機(jī)缺點(diǎn)是工作時(shí)須支腿，不能負(fù)荷行駛，也不適合在松軟或泥濘的場(chǎng)地上工作。澄邁汽車吊怎么樣</p><div
