軸向柱塞泵
是活塞或柱塞的往復(fù)運(yùn)動(dòng)方向與缸體中心軸平行的柱塞泵。
軸向柱塞泵利用與傳動(dòng)軸平行的柱塞在柱塞孔內(nèi)往復(fù)運(yùn)動(dòng)
所產(chǎn)生的容積變化來(lái)進(jìn)行工作的。由于柱塞和柱塞孔都是
圓形零件，加工時(shí)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(yùn)動(dòng)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(kāi)始時(shí)刻不隨供油行程的變化而變化。轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻，從而改變供油量。柱塞泵工作時(shí)，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(yùn)動(dòng)，從而完成泵油任務(wù)，泵油過(guò)程可分為以下三個(gè)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(duì)磨擦副的正常間隙，同時(shí)也會(huì)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(chǎng)提供的資料，軸承的平均使用壽命為10000h，超過(guò)此值就需要更換新口。拆卸下來(lái)的軸承，沒(méi)有專(zhuān)業(yè)檢測(cè)儀器是無(wú)法檢測(cè)出軸承的游隙的，只能采用目測(cè)，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(lái)達(dá)到輸送液體的目的；原動(dòng)機(jī)的機(jī)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(shí)間內(nèi)的變化次數(shù)，理論上與排出壓力無(wú)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(yùn)動(dòng)（或通過(guò)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(lái)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(kāi)，通過(guò)泵閥（吸入閥和排出閥）與管路溝通或閉合。

客戶(hù)對(duì)我們的評(píng)價(jià)：

泵不錯(cuò)啊，代別人買(mǎi)的，沒(méi)說(shuō)有問(wèn)題就是好了。本來(lái)要2臺(tái)，結(jié)果忘記了，在補(bǔ)一臺(tái)。油泵收到后用了一次，力量挺大的，不過(guò)噪音也有點(diǎn)大。客服的態(tài)度不錯(cuò)，回應(yīng)問(wèn)題及時(shí)東西分量很重，剛剛接好就試了試抽的很快。一捅機(jī)油也就一兩分鐘搞定。666666666

油泵收到后用了一次，力量挺大的，不過(guò)噪音也有點(diǎn)大。客服的態(tài)度不錯(cuò)，回應(yīng)問(wèn)題及時(shí)昨天才使用，沒(méi)有出現(xiàn)問(wèn)題，希望一直沒(méi)有問(wèn)題，買(mǎi)家服務(wù)態(tài)度很好

挺好，還可以抽油泵看起來(lái)不錯(cuò)，客服服務(wù)態(tài)度好做工一流，流量快，抽一罐柴油能節(jié)省10分鐘，超級(jí)實(shí)用很好很滿(mǎn)意加油速度很快，就是聲音太大。

收到了！看著還不錯(cuò)，等用了在評(píng)價(jià)寶貝收到，看起來(lái)不錯(cuò)，希望好用 店家態(tài)度不錯(cuò)質(zhì)量挺不錯(cuò)的，使用起來(lái)非常方便，噪音小，而且馬力十足，配得蠻齊的，價(jià)格優(yōu)惠，值得購(gòu)買(mǎi)。 好
