力士樂柱塞泵A10VSO71DR/31R-PKC94N00現(xiàn)貨

REXROTH力士樂軸向柱塞泵與徑向柱塞泵比較，排出壓力高，它一般可在20～50MPa范圍內(nèi)工作，效率也高，徑向尺寸小、結(jié)構(gòu)緊湊、體積小、重量輕。但結(jié)構(gòu)較徑向柱塞泵復雜，加工制造要求高，價格較貴。軸向柱塞泵一般用于機床、冶金、鍛壓、礦山及起重機械的液壓傳動系統(tǒng)中，特別廣泛地應(yīng)用于大功率的液壓傳動系統(tǒng)中。為了提率，在應(yīng)軸向柱塞泵一般都由缸體、配油盤、柱塞和斜盤等主要零件組成。力士樂柱塞泵工作原理缸體內(nèi)有多個柱塞，柱塞是軸向排列的，即柱塞的中心線平行于傳動軸的軸線，因此稱它為軸向柱塞泵。但它又不同于往復式柱塞泵，因為它的柱塞不僅在泵缸內(nèi)做往復運動，而且柱塞和泵缸與斜盤相對有旋轉(zhuǎn)運動。柱塞以一球形端頭與斜盤接觸。在配油盤上有高低壓月形溝槽，它們彼此由隔墻隔開，保證一定的密封性，它們分別與泵的進油口和出油口連通。斜盤的軸線與缸體軸線之間有一傾斜角度。

8、優(yōu)良的吸入性能；允許連續(xù)運行壓力可達28MPa

9、驅(qū)動軸承能承受同向及徑向負載；高的功率/重量比

10、廣范圍的多種控制形式；控制響應(yīng)時間短

11、排量規(guī)格此型號為18m3（另有10、28、45、71、100、140等常見規(guī)格排量）

柱塞泵：A4VSO、A10VSO、A2FO，定量馬達：A2FM，A4FM，A10FM/E， 齒輪泵：0510、AZPF，葉片泵：PV7

直軸斜盤式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱，靠氣壓供油的液壓油箱，在每次啟動機器之后，必須等液壓漬箱達到使用氣壓后，才能操作機械。如液壓油箱的氣壓不足時就啟動機器，會對液壓泵內(nèi)的與滑靴造成拉脫現(xiàn)象，出會造成泵體內(nèi)回程板與壓板的非正常磨損。
