挖掘機壓力無法升高，無力，速度慢主溢流閥壓力過低——全車動作變慢，無力。調節主溢流閥壓力，如閥芯內部被雜質堵住，用柴油清洗；如有磨損，請更換。調整螺釘轉動圈數根據壓力變化再確定，一般情況下增壓邊和標準邊調整螺釘旋轉1圈約為18MPa，調整后在溢流狀態下看壓力是否是你需要調整的壓力。注意：主溢流閥壓力的調整，建議找專業人員上門調試到原

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