柱塞泵工作原理
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。
