葉片泵工作原理：
定子內(nèi)腔型線是圓,轉(zhuǎn)子軸與定子偏心。逆時(shí)針回轉(zhuǎn)時(shí),工作右半轉(zhuǎn)增大,左半轉(zhuǎn) 減小。從兩側(cè)配油盤(pán)的吸、排口吸排油。
兩相鄰葉片轉(zhuǎn)到吸、排油口間的密封區(qū)時(shí),所接觸定子曲線不是與轉(zhuǎn)子同心的圓弧。密封區(qū)的圓心角略大于相鄰葉片所占圓心角。
葉間工作先略有增大,然后略有縮小,會(huì)產(chǎn)生困油現(xiàn)象,但不太嚴(yán)重。通過(guò)在排出口邊緣開(kāi)三角形卸荷槽的方法即可解決。
定子、轉(zhuǎn)子和軸承受徑向力作用,屬非卸荷式葉片泵。工作p不宜太高,q的均勻性也比雙作用差。
移動(dòng)定子可改變偏心的方向及大小,可做成n恒定而q可變的雙向或單向的無(wú)級(jí)變量泵。其中用得較多的是限壓式變量葉片泵。
