挖掘機(jī)壓力無法升高，無力，速度慢主溢流閥壓力過低——全車動(dòng)作變慢，無力。調(diào)節(jié)主溢流閥壓力，如閥芯內(nèi)部被雜質(zhì)堵住，用柴油清洗；如有磨損，請(qǐng)更換。調(diào)整螺釘轉(zhuǎn)動(dòng)圈數(shù)根據(jù)壓力變化再確定，一般情況下增壓邊和標(biāo)準(zhǔn)邊調(diào)整螺釘旋轉(zhuǎn)1圈約為18MPa，調(diào)整后在溢流狀態(tài)下看壓力是否是你需要調(diào)整的壓力。注意：主溢流閥壓力的調(diào)整，建議找專業(yè)人員上門調(diào)試到原

車調(diào)定的壓力，不要隨便自行調(diào)試主溢流閥壓力。旋轉(zhuǎn)馬達(dá)內(nèi)部磨損造成液壓泵內(nèi)泄量大。從旋轉(zhuǎn)減速機(jī)放油口放部分齒輪油，查看是否有金屬粉末。檢查旋轉(zhuǎn)馬達(dá)內(nèi)部零部件是否磨損、減速機(jī)齒面有無異常磨損和缺口。液壓泵排量不足檢查液壓泵調(diào)節(jié)器、內(nèi)部零件如油缸缸體、活塞、閥板、軸等是否磨損，工作異常。如損壞，需要及時(shí)更換。廣東精工牌液壓泵廠家直銷價(jià)液壓泵按流量是否可調(diào)節(jié)可分為:變量泵和定量泵.
