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
結構組成主要有偏心輪、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。偏心輪旋轉一轉，柱塞上下往復運動一次，向下運動吸油，向上運動排油。泵每轉一轉排出的油液體積稱為排量，排量只與泵的結構參數有關。
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帶動活塞做往復運動，實現吸液和排液。
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往復運動所產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
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，必須等液壓漬箱達到使用氣壓后，才能操作機械。如液壓油箱的氣壓不足時就啟動機器，會對液壓泵內的與滑靴造成拉脫現象，出會造成泵體內回程板與壓板的非正常磨損。
徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率低等缺點。上70、80年代發展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足。由于徑向泵結構上的特點，固定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊、壽命長、控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下，改變定子的偏心距實現的，而定于的zui大偏心距為 5—9mm（根據排量大小不同），變量行程很短。且變量機構設計為高壓操縱，由控制閥進行控制。故該泵的響應速度快。徑向結構設計克服了如軸向柱塞泵滑靴偏磨的問題。使其抗沖擊能力大幅度提高。

柱塞和柱塞套是一對精密偶件，經配對研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm
柱塞頭部圓柱面上切有斜槽，并通過徑向孔、軸向孔與頂部相通，其目的是改變循環供油量；柱塞套上制有進、回油孔，均與泵上體內低壓油腔相通，柱塞套裝入泵上體后，應用定位螺釘定位。
柱塞頭部斜槽的位置不同，改變供油量的方法也不同。
出油閥和出油閥座也是一對精密偶件，配對研磨后不能互換，其配合間隙為0.01mm 。
出油閥是一個單向閥，在彈簧壓力作用下，閥上部圓錐面與閥座嚴密配合，其作用是在停供時，將高壓油管與柱塞上端空腔隔絕，防止高壓油管內的油倒流入噴油泵內。
出油閥的下部呈十字斷面，既能導向，又能通過柴油。出油閥的錐面下有一個小的圓柱面，稱為減壓環帶，其作用是在供油終了時，使高壓油管內的油壓迅速下降，避免噴孔處產生滴油現象。當環帶落入閥座內時則使上方容積很快增大，壓力迅速減小，停噴迅速。

Rexroth柱塞泵
工作時，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復運動，從而完成泵油任務，泵油過程可分為以下三個階段。
結論：通過上述討論，得出下列結論
① 柱塞往復運動總行程L是不變的，由凸輪的升程決定。
② 柱塞每循環的供油量大小取決于供油行程，供油行程不受凸輪軸控制是可變的。
③ 供油開始時刻不隨供油行程的變化而變化。
④ 轉動柱塞可改變供油終了時刻，從而改變供油量。
3. 國產系列柱塞式噴油泵
國產系列柱塞泵主要有A、B、P、Z和Ⅰ、Ⅱ、Ⅲ號等系列。系列化是根據柴油機單缸功率范圍對供油量的要求不同，以柱塞行程，泵缸中心距和結構型式為基礎，再分別配以不同尺寸的柱塞直徑，組成若干種在一個工作循環內供油量不等的噴油泵，以滿足各種柴油機的需要。
國產系列噴油泵的工作原理和結構型式基本相同，以A型泵為例介紹柱塞式噴油泵的構造和工作原理。柱塞泵由四大部分組成：分泵、油量調節機構、傳動機構和泵體
國產智能柱塞泵為微處理器智能控制，液晶屏顯示，可與電腦進行通訊，具有工作壓力穩定、脈動小、操作方便等特點。廣泛用于生化、醫藥、化工、環保等行業，滿足以上行業需要連續恒壓、恒流輸送液體的要求。
