油泵的組成結構
一、殼體
二、后蓋（增壓泵）
三、控制閥，控制活塞
四、密封件
五、回轉體總成（主軸及軸承、缸體、斜盤、柱塞、月牙軸承、回程盤、配流盤、球鉸及蝶形彈簧）

力士樂REXROTH油泵有三大類：力士樂柱塞泵，力士樂葉片泵，力士樂齒輪泵

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，利用高速旋轉的葉輪使進口產生真空吸入液體，并在出口連續輸出壓力液體。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吸油和壓油的。當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構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，并且嚴禁在吸入管道上安裝濾油器，吸入管道直徑不小于*數值，另外自吸時一定要把泵先調至全偏角。
在轉速超過1500rpm時，宜采用供油，供油壓力為0.7MPa左右。在開式系統中，供油泵的流量應為該泵的130%，在閉式系統中，供油泵的流量應為該泵的35%。
