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(lái)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。武漢現(xiàn)貨威格士油泵PV046R1D3T1NMR14645
