當凸輪的凸起部分轉過去后,
在彈簧力的作用下,柱塞向下運動,
柱塞上部空間(稱為泵油室)產生真空度,
當柱塞上端面把柱塞套上的進油孔打開后,
充滿在油泵上體油道內的柴油經油孔進入
泵油室,柱塞運動到下止點,進油結束

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
運動時缸內出現(xiàn)負壓,這時一個
單向閥打開液體被吸入缸內,
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zui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
