REXROTH力士樂柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復運動,使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高

REXROTH力士樂軸向柱塞泵是活塞或柱塞的往復運動方向與缸體中心軸平行的柱塞泵。軸向柱塞泵利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復運動所產(chǎn)生的容積變化來進行工作的。由于柱塞和柱塞孔都是圓形零件,加工時可以達到很高的精度配合,因此容積效率高。

力士樂軸向柱塞泵是采用配油盤配油,缸體旋轉(zhuǎn),靠變量頭變量的斜盤式軸向柱塞泵。該泵采用液壓靜力平衡的油膜厚度設計,使缸體與配油盤、滑靴與變量頭之間處于純液體摩擦下運轉(zhuǎn),具有結(jié)構(gòu)簡單、體積小、噪音低、效率高、壽命長和有自吸能力等
