液(ye)壓噴(pen)(pen)射驅動管理(li)系統有兩個主要功能：為(wei)噴(pen)(pen)油(you)(you)器工作(zuo)提供一(yi)個高壓噴(pen)(pen)射驅動發展(zhan)動力；通過內(nei)部控制液(ye)壓油(you)(you)的(de)驅動壓力來控制每個噴(pen)(pen)油(you)(you)器的(de)噴(pen)(pen)射壓力。挖掘機維修最重要的三個參數：操作重量（質量），發(fa)動機(ji)功率和鏟斗斗容。維修挖(wa)掘(jue)機第一臺液壓挖掘(jue)機(ji)由法國波(bo)克蘭工廠發(fa)明(ming)成功。由于液壓技術的應(ying)用(yong)，20世紀40年代(dai)有了在拖拉機(ji)上配裝液壓反(fan)鏟(chan)地懸掛式挖掘(jue)機(ji)。修(xiu)理挖掘機常見的挖掘機結構(gou)(gou)包括，動(dong)力裝(zhuang)置(zhi)，工作(zuo)裝(zhuang)置(zhi)，回(hui)轉機構(gou)(gou)，操縱機構(gou)(gou)，傳動(dong)機構(gou)(gou)，行走機構(gou)(gou)和輔助設施(shi)等。
