軸向柱塞泵
是活塞或柱塞的往復(fù)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(fù)運動
所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是
圓形零件，加工時可以達(dá)到很高的精度配合，因此容積效率高。

柱塞泵柱塞往復(fù)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(fù)運動，從而完成泵油任務(wù)，泵油過程可分為以下三個階段。

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(dá)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(fù)泵是借助于活塞在液缸工作腔內(nèi)的往復(fù)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(fù)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。

很好！不錯帶勁正品。
挺好用的。東西收到，很滿意，快遞也很快??
寶貝已經(jīng)收到了，質(zhì)量非常好，很喜歡，聲音不大比叫滿意，和想象中的一樣比實體店問的便宜很多，非常滿意的一次購物，好評 很好發(fā)貨速度很快，東西質(zhì)量也不錯~加油泵馬力十足，非常滿意，噪音小，做工也很不錯哦！ 非常滿意！寶貝很安靜流量也挺大物流太差勁，產(chǎn)品質(zhì)量還是可以的
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(dān)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(yán)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(xì)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(xì)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！朋友說很好用，不錯。挺好
