油(you)(you)(you)研柱塞泵(beng)(beng)(beng)靠氣壓(ya)(ya)(ya)供油(you)(you)(you)的液壓(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)，在每次啟動機器后(hou)，必須等液壓(ya)(ya)(ya)漬(zi)箱(xiang)(xiang)達到使用(yong)氣壓(ya)(ya)(ya)后(hou)，才能操作機械。直軸斜(xie)盤式柱塞泵(beng)(beng)(beng)分為壓(ya)(ya)(ya)力(li)供油(you)(you)(you)型(xing)(xing)的自(zi)吸(xi)油(you)(you)(you)型(xing)(xing)兩種。壓(ya)(ya)(ya)力(li)供油(you)(you)(you)型(xing)(xing)液壓(ya)(ya)(ya)泵(beng)(beng)(beng)大都采用(yong)有(you)氣壓(ya)(ya)(ya)的油(you)(you)(you)箱(xiang)(xiang)，也有(you)液壓(ya)(ya)(ya)泵(beng)(beng)(beng)本身帶(dai)有(you)補油(you)(you)(you)分泵(beng)(beng)(beng)向液壓(ya)(ya)(ya)泵(beng)(beng)(beng)進油(you)(you)(you)口提供壓(ya)(ya)(ya)力(li)油(you)(you)(you)的。自(zi)吸(xi)油(you)(you)(you)型(xing)(xing)液壓(ya)(ya)(ya)泵(beng)(beng)(beng)的自(zi)吸(xi)油(you)(you)(you)能力(li)很強(qiang)，無需外力(li)供油(you)(you)(you)。對(dui)于自(zi)吸(xi)油(you)(you)(you)型(xing)(xing)柱塞泵(beng)(beng)(beng)，液壓(ya)(ya)(ya)油(you)(you)(you)箱(xiang)(xiang)內的油(you)(you)(you)液不(bu)得低于油(you)(you)(you)標下限(xian)，要(yao)保持足夠數量的液壓(ya)(ya)(ya)油(you)(you)(you)。液壓(ya)(ya)(ya)油(you)(you)(you)的清潔(jie)度越(yue)高(gao)，液壓(ya)(ya)(ya)泵(beng)(beng)(beng)的使用(yong)壽命(ming)越(yue)長

3）油(you)研柱塞(sai)頭部(bu)圓(yuan)柱面上(shang)切(qie)有(you)斜槽，并(bing)通(tong)過(guo)徑向孔(kong)、軸向孔(kong)與頂部(bu)相(xiang)通(tong)，其(qi)目的是改變循環(huan)供油(you)量(liang)；柱塞(sai)套上(shang)制有(you)進(jin)、回(hui)油(you)孔(kong)，均與泵(beng)上(shang)體內(nei)低壓油(you)腔(qiang)相(xiang)通(tong)，柱塞(sai)套裝入泵(beng)上(shang)體后，應用定(ding)位螺(luo)釘定(ding)位。
