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(wù)，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(yīng)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(guān)。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(gòu)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。

發(fā)貨物流好快，平時在網(wǎng)上購物沒這次快，這次速度超快的。在別家看到說這個東西重物流中容易壞 ，買之前還擔心收到貨后是否會有擠壓破損，不過在簽收過程中發(fā)現(xiàn)外包裝很嚴實，拆開后到處打量下沒有損壞，也沒有一絲的磨損。感覺真的很重實，再仔細打量了下，質(zhì)量沒得說。用著 放心。也拿去給安裝師傅看了下，安裝師傅拿在手上轉(zhuǎn)一圈后說 ，東西質(zhì)量很好，比外面實體店的質(zhì)量肯定好也便宜很多，聽到這些話我很開心，東西配件也都很齊全，體積小巧玲瓏，也好看，與網(wǎng)上描述的是的一樣的。賣家的確是花了心思在做事情，值得贊一個。細心的商家就是不一樣，這點都可以看出商家的用心。正尋思著什么時候安裝，現(xiàn)在快冬天了水龍頭和 熱水器出水太小，而且水也是涼和熱，買前客服人員的服務(wù)很到位，主動與我說明貨物的性能及安裝，也說安裝有不明白的可以找他們，客服超好服務(wù)也超好！和圖片一樣。質(zhì)量很好 價格也好美麗 祝生意越來越紅火幫朋友買的，應(yīng)該不錯，好評！
功率很大，配件搭配的也蠻齊全，是電動的，沒有噪聲，性價比不錯，喜歡！ 很滿意東西很好用，客服佷給力！
慮的還是非常細心：試電筆、油管、絲口膠帶、濾網(wǎng)頭配件還是蠻齊全!做工還是蠻厚道！ 滿意朋友說很好用，不錯。很滿意的一次購物 還沒來得及使用 看上去不錯 試過之后在追加評論質(zhì)量挺好的，之前買過一個不錯
朋友說很好用，不錯。用過兩次了，感覺還可以。抽油的速度還比較快的。和圖片一樣。質(zhì)量很好 價格也好美麗 祝生意越來越紅火
