依據作業的負載請求，液壓吊車在施工作業中。呼和浩特吊車租賃電話速度與負(fu)載(zai)(流量與壓力(li))成反比的(de)就是泵的(de)輸出(chu)壓力(li)和(he)流量的(de)乘積是一個常數(shu)，泵的(de)輸出(chu)功(gong)率恒定或(huo)近似恒定:假(jia)如泵操(cao)縱系(xi)(xi)統(tong)(tong)出(chu)現(xian)了(le)故(gu)(gu)障(zhang)，就不能很(hen)好地實(shi)現(xian)動(dong)員機一泵一周一負(fu)荷在不同工況區域優化匹配(pei)狀況，從(cong)而導致我吊車(che)故(gu)(gu)障(zhang)，不能正常作業，所以(yi)我必需(xu)控制(zhi)各(ge)種(zhong)廠(chang)家生(sheng)產的(de)吊車(che)節制(zhi)系(xi)(xi)統(tong)(tong)。處置故(gu)(gu)障(zhang)時，一般先從(cong)電器系(xi)(xi)統(tong)(tong)進手，再檢(jian)查液壓系(xi)(xi)統(tong)(tong)，檢(jian)查機械傳動(dong)系(xi)(xi)統(tong)(tong)。檢(jian)查液壓系(xi)(xi)統(tong)(tong)時，從(cong)協助油(you)路一節制(zhi)油(you)路-主油(you)路-掌握元件(jian)逐步檢(jian)討。

假如發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)輸出(chu)功(gong)率(lv)大大低于額(e)定功(gong)率(lv)，先要測(ce)試發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)自(zi)身的(de)(de)輸出(chu)功(gong)率(lv)。如是施工現場斷定要從簡略的(de)(de)方式進手，先看燃(ran)油濾芯是否(fou)堵塞，燃(ran)油路中(zhong)是否(fou)有(you)調氣的(de)(de)處(chu)所，燃(ran)油泵(beng)中(zhong)的(de)(de)柱塞，噴油頭，出(chu)油間(jian)是否(fou)嚴(yan)重(zhong)(zhong)(zhong)磨損，空氣濾苾進氣是否(fou)通暢，帶渦輪增壓器(qi)的(de)(de)發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)，渦輪增壓器(qi)是否(fou)破壞，發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)是否(fou)快速高(gao)溫，機(ji)(ji)油粘度隆落、遺感缸(gang)髦(mao)封(feng)閉不嚴(yan)緊經比降低，否(fou)缸(gang)套組件磨損造成缸(gang)內嚴(yan)重(zhong)(zhong)(zhong)串氣，發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)氣門封(feng)閉不嚴(yan)等(deng)，這些都是嚴(yan)重(zhong)(zhong)(zhong)影響發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)功(gong)率(lv)的(de)(de)因素。假如除(chu)掉了發(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)自(zi)身輸出(chu)動(dong)(dong)力(li)缺乏(fa)外(wai)，就要斟酌(zhuo)液壓泵(beng)的(de)(de)流量和動(dong)(dong)員機(ji)(ji)的(de)(de)輸出(chu)功(gong)率(lv)的(de)(de)匹配問題了。
