威格士4535V-42A30/45A30/50A30/60A30-1AA-22R葉片泵,雙作用葉片泵的工作原理如圖所示為雙作用葉片泵的工作原理。定子的兩端裝有配流盤,定子3的內(nèi)表面曲線由兩段大半徑圓弧、兩段小半徑圓弧以及四段過渡曲線組成。定子3和轉(zhuǎn)子2的中心重合。在轉(zhuǎn)子2上沿圓周均布開有若干條(- -般為12或16條) 與徑向成-一定角度(一般為13°) 的葉片槽,槽內(nèi)裝有可自由滑動的葉片。在配流盤上,對應(yīng)于定子四段過渡曲線的位置開有四個腰形配流窗口,其中兩個與泵吸油口4連通的是吸油窗口;另外兩個與泵壓油口1連通的是壓油窗口。當(dāng)轉(zhuǎn)子2在傳動軸帶動下轉(zhuǎn)動時,葉片在離心力和底部液壓力(葉片槽底部始終與壓油腔相通)的作用下壓向定子3的內(nèi)表面,在葉片、轉(zhuǎn)子、定子與配流盤之間構(gòu)成若干密封空間。當(dāng)葉片從小半徑曲線段向大半徑曲線滑動時,葉片外伸,這時所構(gòu)成的密封容積由小變大,形成部分真空,油液便經(jīng)吸油窗口吸入;而處于從大半徑曲線段向小半徑曲線滑動的葉片縮回,所構(gòu)成的密封容積由大變小,其中的油液受到擠壓,經(jīng)過壓油窗口壓出這種葉片泵每轉(zhuǎn)-一周,每個密封容腔完成兩次吸、壓油過程,故這種泵稱為雙作用葉片泵。
