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，
加工時可以達到很高的精度配合，因此容積效率高。

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、結構緊湊、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。

在每次啟動機器后，必須等液壓漬箱達

盤式柱塞泵分為壓力供油型的自吸油型
兩種。壓力供油型液壓泵大都采用有氣
壓的油箱，也有液壓泵本身帶有補油分
泵向液壓泵進油口提供壓力油的。
自吸油型液壓泵的自吸油能力很強，無需外力供油。

隨供油行程的變化而變化。轉動柱塞可
改變供油終了時刻，從而改變供油量。
柱塞泵工作時，在噴油泵凸輪軸上的凸

柱塞向上供油，當上行到柱塞上的斜槽
（停供邊）與套筒上的回油孔相通時，
泵油室低壓油路便與柱塞頭部的中孔和
徑向孔及斜槽溝通，油壓驟然下降，
出油閥在彈簧力的作用下迅速關閉，
停止供油。此后柱塞還要上行，
當凸輪的凸起部分轉過去后，
在彈簧的作用下，柱塞又下行。
此時便開始了下一個循環(huán)。
柱塞泵以一個柱塞為原理介，
一個柱塞泵上有兩個單向閥，
并且方向相反，柱塞向一個方向
運動時缸內(nèi)出現(xiàn)負壓，這時一個
單向閥打開液體被吸入缸內(nèi)，
柱塞向另一個方向運動時，
將液體壓縮后另一個單向閥被打開，
被吸入缸內(nèi)的液體被排出。
這種工作方式連續(xù)運動后就形成了連續(xù)供油 。

柱塞泵最重要的部件是軸承，
如果軸承出現(xiàn)游隙，則不能
保證液壓泵內(nèi)部三對磨擦副的
正常間隙，同時也會破壞各
磨擦副的靜液壓支承油膜厚度，
降低柱塞泵軸承的使用壽命。
據(jù)液壓泵制造廠提供的資料，
軸承的平均使用壽命為10000h，
超過此值就需要更換新口。
拆卸下來的軸承，沒有專業(yè)
檢測儀器是無法檢測出軸承的
游隙的，只能采用目測，
如發(fā)現(xiàn)滾柱表面有劃痕或變色，
就必須更換
