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。

柱塞泵柱塞往復運動總行程L是不變的，由凸輪的升程決定。柱塞每循環(huán)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。供油開始時刻不隨供油行程的變化而變化。轉(zhuǎn)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。

當凸輪的凸起部分轉(zhuǎn)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(chǎn)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(nèi)的柴油經(jīng)油孔進入泵油室，柱塞運動到下止點，進油結(jié)束

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。

高壓柱塞泵的使用壓力一般應在10MPa～100MPa之間。它屬于容積式泵，借助工作腔里的容積周期性變化來達到輸送液體的目的；原動機的機械能經(jīng)泵直接轉(zhuǎn)化為輸送液體的壓力能；泵的容量只取決于工作腔容積變化值及其在單位時間內(nèi)的變化次數(shù)，理論上與排出壓力無關。往復泵是借助于活塞在液缸工作腔內(nèi)的往復運動（或通過隔膜、波紋管等撓性元件在工作腔內(nèi)的周期性彈性變形）來使工作腔容積產(chǎn)生周期性變化的。在結(jié)構上，往復泵的工作腔是借助密封裝置與外界隔開，通過泵閥（吸入閥和排出閥）與管路溝通或閉合。
客戶對我們的評價：
功能強大，那么大的一罐油，十幾分鐘就加好了，值得推薦，以后還來你家買。貨收到了，工作的聲音也太吵了貨已收到，好用
東西在用，的確不錯挺好用的。
挺好夠力了效果不錯東西在用，的確不錯質(zhì)量不錯
加油速度很快，就是聲音太大。東西很好用，客服佷給力！我們品牌之前就用過，之前買的是家用增壓泵，效果很好，現(xiàn)在還是他家，真沒讓我失望，這款油泵又快又方便，一看就是正品，材質(zhì)也好，和賣家描述一樣，他家以后我會一如既往的支持，大家可以放心選購，我都是老顧客了，沒有下單的大可放心，人都是憑良心說事，好就好，不好我也不會亂說
