REXROTH柱(zhu)塞(sai)泵(beng)靠氣壓(ya)(ya)(ya)供(gong)油(you)(you)的液(ye)(ye)壓(ya)(ya)(ya)油(you)(you)箱，在每次啟動(dong)機(ji)器后，必(bi)須等液(ye)(ye)壓(ya)(ya)(ya)油(you)(you)箱達(da)到使(shi)用氣壓(ya)(ya)(ya)后，才能(neng)操作機(ji)械(xie)。直軸斜盤(pan)式REXROTH柱(zhu)塞(sai)泵(beng)分為(wei)壓(ya)(ya)(ya)力供(gong)油(you)(you)型的自吸油(you)(you)型兩種。壓(ya)(ya)(ya)力供(gong)油(you)(you)型液(ye)(ye)壓(ya)(ya)(ya)泵(beng)大都采用有(you)氣壓(ya)(ya)(ya)的油(you)(you)箱，也(ye)有(you)液(ye)(ye)壓(ya)(ya)(ya)泵(beng)本身帶有(you)補油(you)(you)分泵(beng)向液(ye)(ye)壓(ya)(ya)(ya)泵(beng)進油(you)(you)口提(ti)供(gong)壓(ya)(ya)(ya)力油(you)(you)的。自吸油(you)(you)型液(ye)(ye)壓(ya)(ya)(ya)泵(beng)的自吸油(you)(you)能(neng)力很強，無需外(wai)力供(gong)油(you)(you)。

A4VSO變量柱塞泵(beng)

規格40至(zhi)1000 

軸向柱塞斜盤結構 

開式回路(lu) 

1系列和(he)3系列 

軸承壽命長 

控制器和主(zhu)動器產品(pin)范圍(wei)廣（如下(xia)） 

同規格(ge)的通(tong)軸結(jie)構，可形成組合(he)泵 

– A4VSO型斜盤結構軸(zhou)向柱塞(sai)變量泵，專為開式回路液壓(ya)驅動設(she)計的。 

– 泵(beng)的流量(liang)正比于泵(beng)的轉(zhuan)速(su)和排量(liang)，調(diao)節它的斜盤傾角可進行排量(liang)的無級調(diao)節。 

– 位置控制斜盤結構  

– 無級變量  – 優(you)良(liang)的吸入(ru)特性  ;

– 允許額定(ding)工作(zuo)壓力可達350 bar   

– 低噪聲  – 長壽命  

– 驅(qu)動軸(zhou)能承受軸(zhou)向(xiang)及(ji)徑向(xiang)負載  

– 優良(liang)的(de)功率/重量比  – 模塊化(hua)設計(ji)  

– 控制(zhi)響應時間(jian)短  

– 通軸結構，可形成組(zu)合泵  – 有(you)斜盤角度指(zhi)示(shi)器  – 安裝位置(zhi)可選  

– 可用HF液體(ti)工(gong)作(zuo)，但運行(xing)參數有所降低
