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

泵的主要性能參數(shù)

1、壓力

關(guān)于壓力，經(jīng)常提到的有下面三個(gè)概念：

A、工作壓力：液壓泵實(shí)際工作時(shí)的輸出壓力稱為工作壓力。工作壓力取決于液壓系統(tǒng)的外負(fù)載的大小和排油管路上的壓力損失，而與液壓泵的流量無關(guān)。

B、額定壓力：液壓泵在正常工作條件下，按試驗(yàn)標(biāo)準(zhǔn)規(guī)定連續(xù)運(yùn)轉(zhuǎn)的較高壓力，通常，工作壓力不得超過額定壓力。一般額定壓力會(huì)在銘牌上標(biāo)出。

C、較高允許壓力：在超過額定壓力的條件下，根據(jù)試驗(yàn)準(zhǔn)規(guī)定，允許液壓泵短暫運(yùn)行的較高壓力值。超過此壓力，泵的泄露會(huì)迅速增加。額定壓力不得超過較高允許壓力，一旦超過，泵就會(huì)出現(xiàn)泄漏。

2、排量和流量

汽車往往有1.6排量，2.0排量，這實(shí)際上就是發(fā)動(dòng)機(jī)旋轉(zhuǎn)一圈所消耗的汽油體積，這跟液壓泵的排量概念是非常類似的。

（1）排量，指在無泄漏的情況下，液壓泵轉(zhuǎn)一圈所能排出的油液體積，這是一個(gè)和液壓泵的機(jī)械結(jié)構(gòu)有關(guān)的參數(shù)，其大小只與液壓泵中密封工作容腔的幾何尺寸和個(gè)數(shù)有關(guān)。從機(jī)械結(jié)構(gòu)來講，有些排量是不變的，即定量泵，有些排量是可變的，即變量泵。

注：一般定量泵因密封性較好，泄露少，在高壓時(shí)效率較高。

（2）流量為泵單位時(shí)間內(nèi)排出的液體體積（L/min），有理論流量Qth、實(shí)際流量Qac、額定流量Qn。

A、理論流量指不考慮泄露的情況下得到的流量值，所以Qth=qn，式中，q為泵的排量（L/r），n為泵的轉(zhuǎn)速（r/min）。

B、實(shí)際流量是考慮了這部分泄露，Qac=Qth-△Q，式中，△Q表示泵的泄露損失，泵運(yùn)轉(zhuǎn)時(shí)油會(huì)從高壓區(qū)泄露到低壓區(qū)

C、額定流量Qn（L/min）指液壓泵在正常工作條件下，按試驗(yàn)標(biāo)準(zhǔn)規(guī)定（如在額定壓力和額定轉(zhuǎn)速下）必須保證的流量。通常會(huì)在銘牌上標(biāo)識(shí)。理論來說，輸出流量會(huì)略低于額定流量值。
