美國威格士VICKERS葉片泵3520V30A14-1AA22 L/R

雙聯(lián)葉片泵　　
單作用：葉片是鑲嵌在槽里的，可以自由滑動(dòng)，當(dāng)旋轉(zhuǎn)產(chǎn)生時(shí)，葉片在離心作用下甩到泵殼上，葉片泵是容積泵，相鄰的兩個(gè)葉片運(yùn)動(dòng)到下邊時(shí)與泵殼和轉(zhuǎn)子封閉的容積zui小，在上邊時(shí)zui大，當(dāng)轉(zhuǎn)子順時(shí)針轉(zhuǎn)動(dòng)時(shí)，相鄰兩葉片經(jīng)歷從zui下邊到zui上邊的過程就是容積增大過程，所以吸油（從第四象限到第二象限）；從zui上到zui下是容積減小過程，所以壓油（從第二到第四象限）。

雙作用：當(dāng)電機(jī)帶動(dòng)轉(zhuǎn)子沿轉(zhuǎn)動(dòng)時(shí)，葉片在離心力和葉片底部壓力油的雙重作用下向外伸出，其頂部緊貼在定子內(nèi)表面上。處于四段同心圓弧上的四個(gè)葉片分別與轉(zhuǎn)子外表面、定子內(nèi)表面及兩個(gè)配流盤組成四個(gè)密封工作油腔。這些油腔隨著轉(zhuǎn)子的轉(zhuǎn)動(dòng)，密封工作油腔產(chǎn)生由小到大或由大到小的變化，可以通過配流盤的吸油窗口（與吸油口相連）或排油窗口（與排油口相連）將油液吸入或壓出。

 在轉(zhuǎn)子每轉(zhuǎn)過程中，每個(gè)工作油腔完成兩次吸油和壓油，所以稱為雙作用式葉片泵，由于高低壓腔相互對稱對稱，軸受力平衡，為卸荷式。

　
雙聯(lián)葉片泵
雙聯(lián)葉片泵是由兩個(gè)單級葉片泵裝在一個(gè)泵體內(nèi)在油路上并聯(lián)組成。兩個(gè)葉片泵的轉(zhuǎn)子由同一傳動(dòng)軸帶動(dòng)旋轉(zhuǎn),有各自獨(dú)立的出油口,兩個(gè)泵可以是相等流量的,也可以是不等流量的。
雙聯(lián)葉片泵常用于有快速進(jìn)給和工作進(jìn)給要求的機(jī)械加工的機(jī)床中,這時(shí)雙聯(lián)泵由一小流量和一大流量泵組成。當(dāng)快速進(jìn)給時(shí),兩個(gè)泵同時(shí)供油（此時(shí)壓力較低）,當(dāng)工作進(jìn)給時(shí),由小流量泵供油（此時(shí)壓力較高）,同時(shí)在油路系統(tǒng)上使大流量泵卸荷,這與采用一個(gè)高壓大流量的泵相比,可以節(jié)省能源,減少油液發(fā)熱。這種雙聯(lián)葉片泵也常用于機(jī)床液壓系統(tǒng)中需要兩個(gè)互不影響的獨(dú)立油路中。
