液壓泵原理
是為液壓傳動(dòng)提供加壓液體的一種液壓元件，是泵的一種。它的功能是把動(dòng)力機(jī)(如電動(dòng)機(jī)和內(nèi)燃機(jī)等)的機(jī)械能轉(zhuǎn)換成液體的壓力能。圖中為單柱塞泵的工作原理。凸輪由電動(dòng)機(jī)帶動(dòng)旋轉(zhuǎn)。當(dāng)凸輪推動(dòng)柱塞向上運(yùn)動(dòng)時(shí)，柱塞和缸體形成的密封體積減小，油液從密封體積中擠出，經(jīng)單向閥排到需要的地方去。當(dāng)凸輪旋轉(zhuǎn)至曲線的下降部位時(shí)，彈簧迫使柱塞向下，形成一定真空度，油 箱中的油液在大氣壓力的作用下進(jìn)入密封容積。凸 輪使柱塞不斷地升降，密封容積周期性地減小和增 大，泵就不斷吸油和排油。

液壓泵是液壓系統(tǒng)的動(dòng)力元件，其功用是給液壓系統(tǒng)提供壓力油，從能量轉(zhuǎn)換角度講，它將是原動(dòng)機(jī)（如發(fā)動(dòng)機(jī)）輸出的機(jī)械能轉(zhuǎn)換為便于輸送的液體的壓力能。液壓馬達(dá)則屬于執(zhí)行元件，它能將輸入液體的壓力能轉(zhuǎn)換為輸出軸轉(zhuǎn)動(dòng)的機(jī)械能，用來拖動(dòng)負(fù)載做功。根據(jù)結(jié)構(gòu)形式，液壓泵與液壓馬達(dá)具體可分為齒輪式、葉片式、柱塞式等類型。
1.液壓泵壓力
液壓泵工作壓力是指泵（或馬達(dá)）在實(shí)際工作時(shí)輸出（或輸入）油液的壓力，由外負(fù)載決定。
額定壓力是指在正常工作條件下，按試驗(yàn)標(biāo)準(zhǔn)規(guī)定能連續(xù)運(yùn)轉(zhuǎn)的zui高壓力。其大小受壽命的限制，若超過額定壓力工作，泵（或馬達(dá)）的使用壽命將會(huì)比設(shè)計(jì)的壽命短。當(dāng)工作壓力大于額定壓力時(shí)稱超載。
2.轉(zhuǎn)速
工作轉(zhuǎn)速是指泵（或馬達(dá)）在工作時(shí)的實(shí)際轉(zhuǎn)動(dòng)速度。
額定轉(zhuǎn)速是指在額定壓力下，能連續(xù)長(zhǎng)時(shí)間正常運(yùn)轉(zhuǎn)的zui高轉(zhuǎn)速。若泵超過額定轉(zhuǎn)速工作將會(huì)造成吸油不足，產(chǎn)生振動(dòng)和大的噪聲，零件會(huì)遭受氣蝕損傷，壽命降低。
zui低穩(wěn)定轉(zhuǎn)速是指馬達(dá)正常運(yùn)轉(zhuǎn)所允許的zui低轉(zhuǎn)速。在此轉(zhuǎn)速下，馬達(dá)不出現(xiàn)爬行現(xiàn)象。
3.排量、流量
排量是指泵（或馬達(dá)）每轉(zhuǎn)一周，由密封容腔幾何尺寸變化而得的排出（或輸入）液體的體積，常用單位是ml/r（毫升/轉(zhuǎn)）。排量可以通過調(diào)節(jié)發(fā)生變化的成為變量泵（或變量馬達(dá)），排量不能變化的成為定量泵（或定量馬達(dá)）。
實(shí)際流量是指泵（或馬達(dá)）工作時(shí)出口處（或進(jìn)口處）的流量。由于泵本身存在內(nèi)泄漏，其實(shí)際流量小于理論流量。由于馬達(dá)本身也存在內(nèi)泄漏，要實(shí)現(xiàn)轉(zhuǎn)速，為補(bǔ)償泄漏量，其輸入實(shí)際流量必須大于理論流量。
4.效率
容積效率，對(duì)液壓泵是指其實(shí)際流量與理論流量的比值。對(duì)液壓馬達(dá)是指其理論流量與實(shí)際流量的比值。
機(jī)械效率，對(duì)液壓泵是指其理論轉(zhuǎn)矩與實(shí)際輸入轉(zhuǎn)矩的比值。對(duì)液壓馬達(dá)其實(shí)際輸出的轉(zhuǎn)矩為理論轉(zhuǎn)矩克服摩擦力后的轉(zhuǎn)矩，因此其機(jī)械效率為實(shí)際輸出轉(zhuǎn)矩與理論轉(zhuǎn)矩的比值。
總效率是指泵（或馬達(dá)）的輸出功率與輸入功率的比值?？傂实扔谌莘e效率與機(jī)械效率的乘積。

力士樂軸向柱塞泵
柱塞泵一般分為單柱塞泵、臥式柱塞泵、軸向柱塞泵和徑向柱塞泵。
單柱塞泵
結(jié)構(gòu)組成主要有偏心輪、柱塞、彈簧、缸體、兩個(gè)單向閥。柱塞與缸體孔之間形成密閉容積。偏心輪旋轉(zhuǎn)一轉(zhuǎn)，柱塞上下往復(fù)運(yùn)動(dòng)一次，向下運(yùn)動(dòng)吸油，向上運(yùn)動(dòng)排油。泵每轉(zhuǎn)一轉(zhuǎn)排出的油液體積稱為排量，排量只與泵的結(jié)構(gòu)參數(shù)有關(guān)。
臥式柱塞泵
臥式柱塞泵是由幾個(gè)柱塞（一般為3個(gè)或6個(gè)）并列安裝，用1根曲軸通過連桿滑塊或由偏心軸直接推動(dòng)柱塞做往復(fù)運(yùn)動(dòng)，實(shí)現(xiàn)吸、排液體的液壓泵。它們也都采用閥式配流裝置，而且大多為定量泵。煤礦液壓支架系統(tǒng)中的乳化液泵一般都是臥式柱塞泵。
乳化液泵用于采煤工作面，為液壓支架提供乳化液，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。
軸向柱塞泵（英文名：Piston pump）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。
徑向柱塞泵可分為閥配流與軸配流兩大類。閥配流徑向柱塞泵存在故障率高、效率低等缺點(diǎn)。上70、80年代發(fā)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zui大偏心距為 5—9mm（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題。使其抗沖擊能力大幅度提高。
