一、單作用葉片泵的工作原理(li)： ATOS葉(xie)(xie)片(pian)(pian)(pian)泵(beng)由轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)1、定(ding)(ding)(ding)(ding)子(zi)(zi)2、葉(xie)(xie)片(pian)(pian)(pian)3、配(pei)油(you)(you)盤(pan)和端蓋等部件所組成。定(ding)(ding)(ding)(ding)子(zi)(zi)的(de)(de)(de)(de)內(nei)(nei)表面(mian)是(shi)圓(yuan)柱形孔。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)和定(ding)(ding)(ding)(ding)子(zi)(zi)之(zhi)間(jian)存在(zai)著偏心。葉(xie)(xie)片(pian)(pian)(pian)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)(de)(de)槽內(nei)(nei)可靈活滑動，在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)動時(shi)的(de)(de)(de)(de)離(li)心力(li)以及通入葉(xie)(xie)片(pian)(pian)(pian)根部壓(ya)(ya)(ya)力(li)油(you)(you)的(de)(de)(de)(de)作(zuo)用下，葉(xie)(xie)片(pian)(pian)(pian)頂(ding)部貼緊在(zai)定(ding)(ding)(ding)(ding)子(zi)(zi)內(nei)(nei)表面(mian)上(shang)，于是(shi)兩(liang)相鄰(lin)葉(xie)(xie)片(pian)(pian)(pian)、配(pei)油(you)(you)盤(pan)、定(ding)(ding)(ding)(ding)子(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)便形成了一個個密封的(de)(de)(de)(de)工(gong)作(zuo)腔(qiang)。當轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)按逆時(shi)針方向(xiang)(xiang)旋轉(zhuan)(zhuan)(zhuan)(zhuan)時(shi)，圖右側的(de)(de)(de)(de)葉(xie)(xie)片(pian)(pian)(pian)向(xiang)(xiang)外伸出(chu)，密封工(gong)作(zuo)腔(qiang)容積(ji)逐漸增(zeng)大，產生真空，于是(shi)通過吸(xi)油(you)(you)口(kou)(kou)6和配(pei)油(you)(you)盤(pan)5上(shang)窗口(kou)(kou)將油(you)(you)吸(xi)入。而在(zai)圖的(de)(de)(de)(de)左側。葉(xie)(xie)片(pian)(pian)(pian)往里縮進，密封腔(qiang)的(de)(de)(de)(de)容積(ji)逐漸縮小，密封腔(qiang)中的(de)(de)(de)(de)油(you)(you)液經(jing)配(pei)油(you)(you)盤(pan)另一窗口(kou)(kou)和壓(ya)(ya)(ya)油(you)(you)口(kou)(kou)1被壓(ya)(ya)(ya)出(chu)而輸出(chu)到(dao)系(xi)統中去。這種泵(beng)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)(zhuan)過程中，吸(xi)油(you)(you)壓(ya)(ya)(ya)油(you)(you)各(ge)一次，故(gu)稱單作(zuo)用泵(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)受到(dao)徑(jing)向(xiang)(xiang)液壓(ya)(ya)(ya)不平衡作(zuo)用力(li)，故(gu)又稱非平衡式(shi)泵(beng)，其軸承負載較大。改(gai)變定(ding)(ding)(ding)(ding)子(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)的(de)(de)(de)(de)偏心量(liang)，便可改(gai)變泵(beng)的(de)(de)(de)(de)排量(liang)，故(gu)這種泵(beng)都是(shi)變量(liang)泵(beng)。 二、雙作用(yong)葉(xie)片泵(beng)的工作原(yuan)理： ATOS葉(xie)(xie)片(pian)泵(beng)(beng)的(de)(de)作(zuo)用(yong)原理和單作(zuo)用(yong)葉(xie)(xie)片(pian)泵(beng)(beng)相似，不(bu)同之(zhi)處只(zhi)在(zai)(zai)于定子表面是(shi)由兩(liang)段長半徑圓弧、兩(liang)段短半徑圓弧和四段過渡曲線八(ba)個部分組成，且定子和轉(zhuan)子是(shi)同心的(de)(de)。在(zai)(zai)圖示轉(zhuan)子順時針(zhen)方(fang)向(xiang)旋轉(zhuan)的(de)(de)情(qing)況下(xia)，密(mi)封工作(zuo)腔的(de)(de)容積在(zai)(zai)左(zuo)上(shang)角和右下(xia)角處逐漸(jian)增大，為(wei)(wei)吸油(you)區(qu)，在(zai)(zai)左(zuo)下(xia)角和右上(shang)角處逐漸(jian)減小，為(wei)(wei)壓(ya)油(you)區(qu)；吸油(you)區(qu)和壓(ya)油(you)區(qu)之(zhi)間有(you)一段封油(you)區(qu)把(ba)它(ta)們(men)隔開(kai)。這種泵(beng)(beng)的(de)(de)轉(zhuan)子每轉(zhuan)一轉(zhuan)，每個密(mi)封工作(zuo)腔完成吸油(you)和壓(ya)油(you)動作(zuo)各兩(liang)次(ci)，所(suo)以稱(cheng)為(wei)(wei)雙作(zuo)用(yong)葉(xie)(xie)片(pian)泵(beng)(beng)。泵(beng)(beng)的(de)(de)兩(liang)個吸油(you)區(qu)和兩(liang)個壓(ya)油(you)區(qu)是(shi)徑向(xiang)對稱(cheng)的(de)(de)，作(zuo)用(yong)在(zai)(zai)轉(zhuan)子上(shang)的(de)(de)液壓(ya)力徑向(xiang)平(ping)(ping)衡，所(suo)以又稱(cheng)為(wei)(wei)平(ping)(ping)衡式葉(xie)(xie)片(pian)泵(beng)(beng)。 雙作用(yong)葉(xie)片(pian)泵(beng)的(de)瞬時流量(liang)是脈動(dong)(dong)的(de)，當葉(xie)片(pian)數為4的(de)倍數時脈動(dong)(dong)率(lv)小(xiao)。為此，雙作用(yong)葉(xie)片(pian)泵(beng)的(de)葉(xie)片(pian)數一般都取12或(huo)16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
