①當(dāng)油液中混入空氣后，易在泵的高壓區(qū)形成氣穴，并以壓力波的形式傳播，造成油液振蕩，導(dǎo)致系統(tǒng)產(chǎn)生氣蝕噪聲。主要原因是：液壓泵的濾油器、進(jìn)油管堵塞或油液黏度過高;液壓泵、先導(dǎo)泵軸端油封損壞或進(jìn)油管密封不良;油箱油位過低，使液壓泵進(jìn)油管吸空。 </p> <p> ②液壓泵零件過度磨損，如柱塞泵的缸體與配流盤、柱塞與柱塞孔等磨損，使泵內(nèi)漏嚴(yán)重，當(dāng)泵輸出高壓、小流量油液時(shí)將產(chǎn)生流量脈動(dòng)，引發(fā)較高噪聲。此時(shí)可適當(dāng)加大先導(dǎo)系統(tǒng)變量機(jī)構(gòu)的偏角，以改善內(nèi)漏對(duì)泵輸出流量的影響。當(dāng)泵的伺服閥閥芯、控制流量的活塞局部磨損、拉傷后會(huì)使活塞在移動(dòng)過程中產(chǎn)生脈動(dòng)，導(dǎo)致泵的輸出流量和壓力波動(dòng)，在泵出口處產(chǎn)生較大振動(dòng)和噪聲。此時(shí)可對(duì)磨損、拉傷嚴(yán)重的元件進(jìn)行刷鍍、研配或更換處理。

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)致平衡閥間歇性開啟；二是液壓缸無(wú)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(shí)使平衡閥開啟。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，這樣才能產(chǎn)生足夠的壓力來(lái)推動(dòng)柱塞，頂開單向閥，使無(wú)桿腔回油。</p><p>

缺乏專業(yè)的檢測(cè)技術(shù)人員，輕量化汽車起重機(jī)在結(jié)構(gòu)、外形以及零件尺寸上均發(fā)生了改變，因此，在實(shí)際檢測(cè)中檢測(cè)人員需要更新檢測(cè)技術(shù)，熟練掌握檢測(cè)項(xiàng)目以及對(duì)應(yīng)的指標(biāo)要求，但是實(shí)際上存在的檢測(cè)人員大多數(shù)是早期的檢測(cè)人員，對(duì)于輕量化汽車起重機(jī)實(shí)際檢測(cè)技術(shù)以及要求相關(guān)檢測(cè)指標(biāo)缺乏足夠的認(rèn)識(shí)。檢測(cè)技術(shù)人員作為輕量化汽車起重機(jī)安全檢測(cè)的主體，其專業(yè)知識(shí)以及操作技能對(duì)檢測(cè)結(jié)果有較大影響。大噸位的起重機(jī)為了提高起重能力大多數(shù)都采用同步伸縮。</p><div
