工作原理靠曲軸的旋轉(zhuǎn)帶動(dòng)活塞做往復(fù)運(yùn)動(dòng),實(shí)現(xiàn)吸液和排液。軸向式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。直軸斜盤(pán)式直軸斜盤(pán)式柱塞泵分為壓力供油型和自吸油型兩種。壓力供油型液壓泵大都是采用有氣壓的油箱,靠氣壓供油的液壓油箱,在每次啟動(dòng)機(jī)器之后,必須等液壓漬箱達(dá)到使用氣壓后,才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就啟動(dòng)機(jī)器,會(huì)對(duì)液壓泵內(nèi)的與滑靴造成拉脫現(xiàn)象,出會(huì)造成泵體內(nèi)回程板與壓板的非正常磨損。徑向式徑向柱塞泵可分為閥配流與軸配流兩大類(lèi)。閥配流徑向柱塞泵存在故障率高效率低等缺點(diǎn)。國(guó)際上00年展的軸配流徑向柱塞泵克服了閥配流徑向柱塞泵的不足。由于徑向泵結(jié)構(gòu)上的特點(diǎn),固定了軸配流徑向柱塞泵比軸向柱塞泵耐沖擊壽命長(zhǎng)控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下,改變定子的偏心距實(shí)現(xiàn)的,而定于的偏心距為—mm根據(jù)排量大小不同,變量行程很短。且變量機(jī)構(gòu)設(shè)計(jì)為高壓操縱,由控制閥進(jìn)行控制。故該泵的響應(yīng)速度快。徑向結(jié)構(gòu)設(shè)計(jì)克服了如軸向柱塞泵滑靴偏磨的問(wèn)題。使其抗沖擊能力大幅度提高。液壓式液壓柱塞泵靠氣壓供油的液壓油箱,在每次啟動(dòng)機(jī)器后,必須等液壓油箱達(dá)到使用氣壓后,才能操作機(jī)械。直軸斜盤(pán)式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱,也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng),無(wú)需外力供油。柱塞泵的工作原理柱塞泵柱塞往復(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)程可分為以下兩個(gè)階段。進(jìn)油過(guò)程當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)去后,在彈簧力的作用下,柱塞向下運(yùn)動(dòng),柱塞上部空間稱(chēng)為泵油室產(chǎn)生真空度,當(dāng)柱塞上端面把柱塞套上的進(jìn)油孔打開(kāi)后,充滿(mǎn)在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室,柱塞運(yùn)動(dòng)到下止點(diǎn),進(jìn)油結(jié)束回油過(guò)程柱塞向上供油,當(dāng)上行到柱塞上的斜槽停供邊與套筒上的回油孔相通時(shí),泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通,油壓驟然下降,出油閥在彈簧力的作用下迅速關(guān)閉,。
