          雙聯(lián)葉片泵  
          單作用:葉片是鑲嵌在槽里的,可以自由滑動,當(dāng)旋轉(zhuǎn)產(chǎn)生時,葉片在離心作用下甩到泵殼上,葉片泵是容積泵,相鄰的兩個葉片運(yùn)動到下邊時與泵殼和轉(zhuǎn)子封閉的容積zui小,在上邊時zui大,當(dāng)轉(zhuǎn)子順時針轉(zhuǎn)動時,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)帶動轉(zhuǎn)子沿轉(zhuǎn)動時,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葉片分別與轉(zhuǎn)子外表面、定子內(nèi)表面及兩個配流盤組成四個密封工作油腔。這些油腔隨著轉(zhuǎn)子的轉(zhuǎn)動,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)葉片泵是由兩個單級葉片泵裝在一個泵體內(nèi)在油路上并聯(lián)組成。兩個葉片泵的轉(zhuǎn)子由同一傳動軸帶動旋轉(zhuǎn),有各自獨(dú)立的出油口,兩個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,兩個泵同時供油(此時壓力較低),當(dāng)工作進(jìn)給時,由小流量泵供油(此時壓力較高),同時在油路系統(tǒng)上使大流量泵卸荷,這與采用一個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)中需要兩個互不影響的獨(dú)立油路中。
