力士樂REXROTH油泵特點:力士樂柱塞泵根據傾斜元件的不同,有斜盤式和斜軸式兩種。斜盤式是斜盤相對
回轉的缸體有一傾斜角度,而引起柱塞在泵缸中往復
運動。傳動軸軸線和缸體軸線是*的。這種結構較
簡單,轉速較高,但工作條件要求高,柱塞端部與斜
盤的接觸部往往是薄弱環(huán)節(jié)。斜軸式的斜盤軸線
與傳動軸軸線是*的。它是由于柱塞缸體相對傳動
軸傾斜一角度而使柱塞作往復運動。流量調節(jié)依靠擺
動柱塞缸體的角度來實現,故有的又稱擺缸式。它與
斜盤式相比,工作可靠,流量大,但結構復雜。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范圍內工作,效率也高,徑向尺寸小、結構緊湊、體積小、重量輕。但結構較徑向柱塞泵復雜,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,特別廣泛地應用于大功率的液壓傳動系統(tǒng)中。
為了提高效率,在應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。缸體內有多個柱塞
,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做往復運動,
而且柱塞和泵缸與斜盤相對有旋轉運動。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。力士樂油泵有開槽控制的斜盤設計,連續(xù)可變的排量,良好的自吸性,
允許連續(xù)工作壓力350bar,低噪音,使用壽命長,驅
動軸能吸收軸向和徑向載荷,模塊化設計,通軸驅動
控制時間短,泵位置可選,安裝位置也可以選擇,可
在降低的工作參數下用HFC液工作。力士樂油泵的控制方式有三種,壓力控制器(如A10VS045DR/31R-
PPA12NOO),還有就是壓力和流量控制器
