A4VG56EP4D7/32R-NZC02N005S柱塞泵柱塞泵是液壓系統(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、效率高和流量調(diào)節(jié)方便等優(yōu)點，被廣泛應用于高壓、大流量和流量需要調(diào)節(jié)的場合，諸如液壓機、工程機械和船舶中。
柱塞泵一般分為單柱塞泵、臥式柱塞泵、軸向柱塞泵和徑向柱塞泵。
單柱塞泵
結(jié)構(gòu)組成主要有偏心輪、柱塞、彈簧、缸體、兩個單向閥。柱塞與缸體孔之間形成密閉容積。偏心輪旋轉(zhuǎn)一轉(zhuǎn)，柱塞上下往復運動一次，向下運動吸油，向上運動排油。泵每轉(zhuǎn)一轉(zhuǎn)排出的油液體積稱為排量，排量只與泵的結(jié)構(gòu)參數(shù)有關。
臥式柱塞泵
臥式柱塞泵是由幾個柱塞（一般為3個或6個）并列安裝，用1根曲軸通過連桿滑塊或由偏心軸直接推動柱塞做往復運動，實現(xiàn)吸、排液體的液壓泵。它們也都采用閥式配流裝置，而且大多為定量泵。煤礦液壓支架系統(tǒng)中的乳化液泵一般都是臥式柱塞泵。
乳化液泵用于采煤工作面，為液壓支架提供乳化液，工作原理靠曲軸的旋轉(zhuǎn)帶動活塞做往復運動，實現(xiàn)吸液和排液。
軸向式
軸向柱塞泵（英文名：Piston pump）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，可以達到很高的精度配合，因此容積效率高。
直軸斜盤式
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，必須等液壓油箱達到使用氣壓后，才能操作機械。如果液壓油箱的氣壓不足時就啟動機器，會對液壓泵內(nèi)的滑靴造成拉脫現(xiàn)象，會造成泵體內(nèi)回程板與壓板的非正常磨損。
