單柱(zhu)液(ye)(ye)壓(ya)機開始(shi)使用水做(zuo)為工作中物(wu)質，在之后改成在水中添(tian)加其少許(xu)乳化(hua)液(ye)(ye)而成的乳化(hua)油，以提升潤(run)滑性和降(jiang)低生銹。單柱(zhu)液(ye)(ye)壓(ya)機的它(ta)的潤(run)滑性和耐蝕性貼近油，且含油率液(ye)(ye)壓(ya)機的驅(qu)動(dong)系統(tong)關鍵有泵立(li)即驅(qu)動(dong)和泵-蓄能器驅(qu)動(dong)二種形式。

單柱液(ye)(ye)壓機(ji)(ji)系(xi)統的泵(beng)(beng)向液(ye)(ye)壓油缸給(gei)予高壓工作液(ye)(ye)體，在運(yun)轉的歷程(cheng)中(zhong)為配流(liu)閥(fa)是用于更改(gai)供液(ye)(ye)方位，調速閥(fa)用于調整(zheng)系(xi)統的限制氣(qi)體壓強(qiang)，與(yu)此同時(shi)起安(an)全(quan)性溢出功效(xiao)。這類驅動系(xi)統階段少,構造簡易,氣(qi)體壓強(qiang)能按需要(yao)的工作中(zhong)力(li)全(quan)自動調整(zheng)，降低了電(dian)力(li)耗費，但須由液(ye)(ye)壓機(ji)(ji)的工作中(zhong)力(li)和運(yun)行速率來決策泵(beng)(beng)以(yi)及(ji)驅動電(dian)動機(ji)(ji)的容積。這類形式的驅動系(xi)統多應(ying)用于大中(zhong)小(xiao)型液(ye)(ye)壓機(ji)(ji)，也(ye)有效(xiao)泵(beng)(beng)立(li)即驅動的大中(zhong)型（如120000千牛賣家）隨意煅造液(ye)(ye)壓機(ji)(ji)。

單柱液壓(ya)(ya)機的(de)(de)驅(qu)(qu)動系(xi)(xi)統(tong)(tong)中會有(you)一(yi)個或是(shi)是(shi)一(yi)組(zu)蓄(xu)能(neng)器，在實際操(cao)作(zuo)時(shi)其(qi)泵所提供(gong)的(de)(de)高壓(ya)(ya)工(gong)(gong)作(zuo)液多量(liang)(liang)時(shi)，由蓄(xu)能(neng)器存儲；而(er)當供(gong)應量(liang)(liang)不夠于(yu)必須時(shi)，便由蓄(xu)能(neng)器填補提供(gong)。選用(yong)(yong)這類(lei)系(xi)(xi)統(tong)(tong)可以按高壓(ya)(ya)工(gong)(gong)作(zuo)液的(de)(de)均(jun)值(zhi)使用(yong)(yong)量(liang)(liang)采(cai)用(yong)(yong)泵和電(dian)機的(de)(de)容(rong)積，但由于(yu)工(gong)(gong)作(zuo)液的(de)(de)氣體壓(ya)(ya)強是(shi)不變的(de)(de)，電(dian)磁能(neng)使用(yong)(yong)量(liang)(liang)比較大，而(er)且系(xi)(xi)統(tong)(tong)的(de)(de)過(guo)程(cheng)多，構造比較復雜。這類(lei)驅(qu)(qu)動系(xi)(xi)統(tong)(tong)多用(yong)(yong)以大中型液壓(ya)(ya)機，或是(shi)用(yong)(yong)一(yi)套驅(qu)(qu)動系(xi)(xi)統(tong)(tong)驅(qu)(qu)動多臺液壓(ya)(ya)機。
