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。

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

柱塞泵最重要的部件是軸承，如果軸承出現游隙，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，沒有專業檢測儀器是無法檢測出軸承的游隙的，只能采用目測，如發現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；原動機的機械能經泵直接轉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的變化次數，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的往復運動（或通過隔膜、波紋管等撓性元件在工作腔內的周期性彈性變形）來使工作腔容積產生周期性變化的。在結構上，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：

東西很小巧，還沒用，用完在追評。賣家態度很好，發貨也很快，包裝的嚴實。~~產品與淘寶圖片一致，外觀滿意，不過剛收到還沒使用，使用后再評價！買了好多臺了，還不錯。希望老板可以有泵頭配，壞了修起來方便點。

包裝整齊，沒有壞的地方，客戶反應好用，質量很好，滿意的一次購物！還沒用呢，看外表做工沒問題，等用過再來追加評價

寶貝已經收到 使用方便 做工好 功能強 材質經久耐用 整體設計人性化 把手手感好 質量很棒 非常滿意不錯發貨速度很快，東西質量也不錯~非常強大，聲音又小，滿意非常強大，聲音又小，滿意

流量不是那么理想還沒用。上次的就是聲音大寶貝收到，看起來不錯，希望好用 店家態度不錯
