一個完整的液(ye)壓系統(tong)是(shi)由五個部(bu)分組成，即動力(li)元件(jian)、執行元件(jian)、控(kong)制元件(jian)、輔助(zhu)元件(jian)和液(ye)壓油。
1、動(dong)力元件(jian)：動(dong)力元件(jian)的(de)(de)是將原動(dong)機的(de)(de)機械能轉換成(cheng)液體的(de)(de)壓(ya)(ya)力能，指液壓(ya)(ya)系統中的(de)(de)油(you)泵，它向(xiang)整個液壓(ya)(ya)系統提供動(dong)力。液壓(ya)(ya)泵的(de)(de)一般有齒輪泵、葉片泵和(he)柱塞泵等；
2、執(zhi)行(xing)(xing)元(yuan)件：執(zhi)行(xing)(xing)元(yuan)件(如(ru)液(ye)壓(ya)缸和液(ye)壓(ya)馬達)的(de)作用是將液(ye)體的(de)壓(ya)力能轉換為機械能，驅動(dong)負(fu)載作直線往(wang)復運(yun)(yun)動(dong)或回轉運(yun)(yun)動(dong)；
3、控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)元件:控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)元件(即各種液壓(ya)閥(fa)(fa)(fa)(fa)(fa))在液壓(ya)系統中控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)和(he)(he)調(diao)(diao)節液體(ti)的壓(ya)力(li)(li)、流(liu)(liu)(liu)(liu)量和(he)(he)方向(xiang)。根(gen)據(ju)(ju)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)功(gong)能(neng)的不(bu)同(tong)(tong)，液壓(ya)閥(fa)(fa)(fa)(fa)(fa)可(ke)分為壓(ya)力(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)、流(liu)(liu)(liu)(liu)量控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)和(he)(he)方向(xiang)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)。壓(ya)力(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)又分為減壓(ya)閥(fa)(fa)(fa)(fa)(fa)、順(shun)序(xu)閥(fa)(fa)(fa)(fa)(fa)、溢流(liu)(liu)(liu)(liu)閥(fa)(fa)(fa)(fa)(fa)、壓(ya)力(li)(li)繼(ji)電器等(deng)；流(liu)(liu)(liu)(liu)量控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)包括節流(liu)(liu)(liu)(liu)閥(fa)(fa)(fa)(fa)(fa)、調(diao)(diao)整閥(fa)(fa)(fa)(fa)(fa)、分流(liu)(liu)(liu)(liu)集(ji)流(liu)(liu)(liu)(liu)閥(fa)(fa)(fa)(fa)(fa)等(deng)；方向(xiang)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)包括單向(xiang)閥(fa)(fa)(fa)(fa)(fa)、液控(kong)(kong)(kong)(kong)(kong)單向(xiang)閥(fa)(fa)(fa)(fa)(fa)、梭閥(fa)(fa)(fa)(fa)(fa)、換(huan)向(xiang)閥(fa)(fa)(fa)(fa)(fa)等(deng)。根(gen)據(ju)(ju)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)方式不(bu)同(tong)(tong)，液壓(ya)閥(fa)(fa)(fa)(fa)(fa)可(ke)分為開(kai)關(guan)式控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)、定(ding)值控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)和(he)(he)比(bi)例控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)閥(fa)(fa)(fa)(fa)(fa)；
4、輔助元件包括油箱、濾油器、油管(guan)及管(guan)接頭、密封(feng)圈、壓力(li)表、油位(wei)油溫計等(deng)；
5、液(ye)(ye)壓(ya)(ya)油是液(ye)(ye)壓(ya)(ya)系(xi)統中傳遞能量的工作介質，有各種礦物油、乳化(hua)液(ye)(ye)和合成型液(ye)(ye)壓(ya)(ya)油等(deng)幾(ji)大類。
