一、單作用葉片泵的工作原理： ATOS葉片(pian)(pian)(pian)(pian)泵(beng)(beng)(beng)由轉(zhuan)子(zi)(zi)(zi)1、定(ding)(ding)子(zi)(zi)(zi)2、葉片(pian)(pian)(pian)(pian)3、配油(you)(you)(you)盤(pan)和(he)(he)端(duan)蓋(gai)等部件所組成。定(ding)(ding)子(zi)(zi)(zi)的(de)(de)(de)(de)內(nei)表(biao)面是圓柱形(xing)孔。轉(zhuan)子(zi)(zi)(zi)和(he)(he)定(ding)(ding)子(zi)(zi)(zi)之(zhi)間存在(zai)(zai)(zai)著偏(pian)心(xin)。葉片(pian)(pian)(pian)(pian)在(zai)(zai)(zai)轉(zhuan)子(zi)(zi)(zi)的(de)(de)(de)(de)槽(cao)內(nei)可(ke)靈活(huo)滑動，在(zai)(zai)(zai)轉(zhuan)子(zi)(zi)(zi)轉(zhuan)動時的(de)(de)(de)(de)離心(xin)力以及通入(ru)葉片(pian)(pian)(pian)(pian)根部壓(ya)力油(you)(you)(you)的(de)(de)(de)(de)作(zuo)用(yong)下，葉片(pian)(pian)(pian)(pian)頂部貼緊在(zai)(zai)(zai)定(ding)(ding)子(zi)(zi)(zi)內(nei)表(biao)面上，于是兩(liang)相鄰葉片(pian)(pian)(pian)(pian)、配油(you)(you)(you)盤(pan)、定(ding)(ding)子(zi)(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)(zi)間便形(xing)成了(le)一(yi)個個密封的(de)(de)(de)(de)工(gong)作(zuo)腔。當轉(zhuan)子(zi)(zi)(zi)按逆時針方向旋轉(zhuan)時，圖(tu)右(you)側的(de)(de)(de)(de)葉片(pian)(pian)(pian)(pian)向外伸出，密封工(gong)作(zuo)腔容積(ji)逐漸增大(da)，產(chan)生真空(kong)，于是通過吸(xi)油(you)(you)(you)口(kou)6和(he)(he)配油(you)(you)(you)盤(pan)5上窗口(kou)將油(you)(you)(you)吸(xi)入(ru)。而在(zai)(zai)(zai)圖(tu)的(de)(de)(de)(de)左(zuo)側。葉片(pian)(pian)(pian)(pian)往里縮(suo)進(jin)，密封腔的(de)(de)(de)(de)容積(ji)逐漸縮(suo)小(xiao)，密封腔中(zhong)的(de)(de)(de)(de)油(you)(you)(you)液(ye)經配油(you)(you)(you)盤(pan)另一(yi)窗口(kou)和(he)(he)壓(ya)油(you)(you)(you)口(kou)1被壓(ya)出而輸出到系(xi)統中(zhong)去(qu)。這種泵(beng)(beng)(beng)在(zai)(zai)(zai)轉(zhuan)子(zi)(zi)(zi)轉(zhuan)一(yi)轉(zhuan)過程中(zhong)，吸(xi)油(you)(you)(you)壓(ya)油(you)(you)(you)各一(yi)次，故(gu)(gu)稱(cheng)單(dan)作(zuo)用(yong)泵(beng)(beng)(beng)。轉(zhuan)子(zi)(zi)(zi)受到徑(jing)向液(ye)壓(ya)不平衡(heng)作(zuo)用(yong)力，故(gu)(gu)又稱(cheng)非(fei)平衡(heng)式泵(beng)(beng)(beng)，其軸承負載較(jiao)大(da)。改變定(ding)(ding)子(zi)(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)(zi)間的(de)(de)(de)(de)偏(pian)心(xin)量，便可(ke)改變泵(beng)(beng)(beng)的(de)(de)(de)(de)排量，故(gu)(gu)這種泵(beng)(beng)(beng)都是變量泵(beng)(beng)(beng)。 二、雙作用葉片泵的(de)工作原理： ATOS葉片(pian)泵的(de)(de)作(zuo)(zuo)用(yong)(yong)原理(li)和(he)單作(zuo)(zuo)用(yong)(yong)葉片(pian)泵相(xiang)似，不同之(zhi)處只在(zai)(zai)(zai)于定子(zi)(zi)表面是(shi)由兩段(duan)長半徑(jing)圓弧、兩段(duan)短(duan)半徑(jing)圓弧和(he)四段(duan)過渡曲線八個(ge)部分組成(cheng)，且定子(zi)(zi)和(he)轉(zhuan)子(zi)(zi)是(shi)同心的(de)(de)。在(zai)(zai)(zai)圖示轉(zhuan)子(zi)(zi)順時針方向(xiang)(xiang)(xiang)旋轉(zhuan)的(de)(de)情況下(xia)，密封工(gong)作(zuo)(zuo)腔(qiang)的(de)(de)容積在(zai)(zai)(zai)左(zuo)上角和(he)右下(xia)角處逐漸增大，為吸油(you)區(qu)，在(zai)(zai)(zai)左(zuo)下(xia)角和(he)右上角處逐漸減小(xiao)，為壓(ya)油(you)區(qu)；吸油(you)區(qu)和(he)壓(ya)油(you)區(qu)之(zhi)間(jian)有(you)一段(duan)封油(you)區(qu)把它(ta)們隔開。這種泵的(de)(de)轉(zhuan)子(zi)(zi)每(mei)轉(zhuan)一轉(zhuan)，每(mei)個(ge)密封工(gong)作(zuo)(zuo)腔(qiang)完成(cheng)吸油(you)和(he)壓(ya)油(you)動作(zuo)(zuo)各兩次，所以稱為雙作(zuo)(zuo)用(yong)(yong)葉片(pian)泵。泵的(de)(de)兩個(ge)吸油(you)區(qu)和(he)兩個(ge)壓(ya)油(you)區(qu)是(shi)徑(jing)向(xiang)(xiang)(xiang)對稱的(de)(de)，作(zuo)(zuo)用(yong)(yong)在(zai)(zai)(zai)轉(zhuan)子(zi)(zi)上的(de)(de)液壓(ya)力徑(jing)向(xiang)(xiang)(xiang)平(ping)衡，所以又稱為平(ping)衡式(shi)葉片(pian)泵。 雙作用(yong)葉(xie)片(pian)(pian)泵的(de)(de)(de)瞬時(shi)流量是(shi)脈動的(de)(de)(de)，當葉(xie)片(pian)(pian)數為4的(de)(de)(de)倍數時(shi)脈動率小。為此，雙作用(yong)葉(xie)片(pian)(pian)泵的(de)(de)(de)葉(xie)片(pian)(pian)數一般都取12或16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
