德國REXROTH力士樂油泵A10VSO100DR，rexroth液壓油泵，液壓油泵

力士樂油泵可以分為容積式和非容積室（蝸輪式）兩種。非容積式有離心泵、軸流泵等，利用高速旋轉(zhuǎn)的葉輪使進口產(chǎn)生真空吸入液體，并在出口連續(xù)輸出壓力液體。這種泵進口與出口相通，效率隨液體粘度增加而降低，并且輸出液體量隨出口壓力升高而顯著減少。
容積式泵是通過一個封閉的空間容積的變化來實現(xiàn)吸油和壓油的。當(dāng)這個封閉容積由小變大時進行吸油，由大變小時進行壓油。典型的為力士樂柱塞泵，柱塞從缸孔中拉出時吸油，壓進時壓油。這種泵進口與出口是被隔開的，效率取決于隔開吸壓油腔的各對運動零件間的結(jié)構(gòu)工藝間隙及油液的粘度等。粘度越高效率越高，輸油量幾乎保持不變（因效率略有影響，另外壓力升高至18MPa，油液會被壓縮1%）。

力士樂油泵的供油和自吸Rexroth柱塞泵具有一定的自吸能力，但自吸的高度不宜超過500mm，并且嚴(yán)禁在吸入管道上安裝濾油器，吸入管道直徑不小于*數(shù)值，另外自吸時一定要把泵先調(diào)至全偏角。
在轉(zhuǎn)速超過1500rpm時，宜采用供油，供油壓力為0.7MPa左右。在開式系統(tǒng)中，供油泵的流量應(yīng)為該泵的130%，在閉式系統(tǒng)中，供油泵的流量應(yīng)為該泵的35%。
