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(guò)程就是容積增大過(guò)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(guò)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(pán)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(guò)配流盤(pán)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(guò)程中,每個(gè)工作油腔完成兩次吸油和壓油,所以稱(chēng)為雙作用式葉片泵,由于高低壓腔相互對(duì)稱(chēng)對(duì)稱(chēng),軸受力平衡,為卸荷式。
