一(yi)、單作(zuo)用葉片(pian)泵的工(gong)作(zuo)原理： ATOS葉(xie)(xie)片(pian)(pian)泵(beng)(beng)由轉(zhuan)子(zi)(zi)1、定(ding)子(zi)(zi)2、葉(xie)(xie)片(pian)(pian)3、配(pei)油(you)(you)盤和端(duan)蓋等部(bu)件所(suo)組成。定(ding)子(zi)(zi)的內表面(mian)是圓柱形孔。轉(zhuan)子(zi)(zi)和定(ding)子(zi)(zi)之間存在(zai)著偏心。葉(xie)(xie)片(pian)(pian)在(zai)轉(zhuan)子(zi)(zi)的槽內可靈(ling)活滑動(dong)(dong)，在(zai)轉(zhuan)子(zi)(zi)轉(zhuan)動(dong)(dong)時的離心力以及通入(ru)(ru)葉(xie)(xie)片(pian)(pian)根部(bu)壓(ya)(ya)(ya)力油(you)(you)的作(zuo)用(yong)(yong)下，葉(xie)(xie)片(pian)(pian)頂部(bu)貼緊在(zai)定(ding)子(zi)(zi)內表面(mian)上(shang)，于是兩(liang)相鄰葉(xie)(xie)片(pian)(pian)、配(pei)油(you)(you)盤、定(ding)子(zi)(zi)和轉(zhuan)子(zi)(zi)間便形成了一(yi)個個密(mi)(mi)封(feng)(feng)(feng)的工(gong)作(zuo)腔(qiang)(qiang)。當轉(zhuan)子(zi)(zi)按逆時針(zhen)方向旋(xuan)轉(zhuan)時，圖右側的葉(xie)(xie)片(pian)(pian)向外伸出(chu)，密(mi)(mi)封(feng)(feng)(feng)工(gong)作(zuo)腔(qiang)(qiang)容(rong)積(ji)逐漸(jian)增大，產(chan)生(sheng)真空，于是通過吸(xi)油(you)(you)口6和配(pei)油(you)(you)盤5上(shang)窗口將油(you)(you)吸(xi)入(ru)(ru)。而(er)在(zai)圖的左側。葉(xie)(xie)片(pian)(pian)往(wang)里縮(suo)(suo)進，密(mi)(mi)封(feng)(feng)(feng)腔(qiang)(qiang)的容(rong)積(ji)逐漸(jian)縮(suo)(suo)小，密(mi)(mi)封(feng)(feng)(feng)腔(qiang)(qiang)中的油(you)(you)液經配(pei)油(you)(you)盤另一(yi)窗口和壓(ya)(ya)(ya)油(you)(you)口1被壓(ya)(ya)(ya)出(chu)而(er)輸出(chu)到系統中去(qu)。這(zhe)種泵(beng)(beng)在(zai)轉(zhuan)子(zi)(zi)轉(zhuan)一(yi)轉(zhuan)過程中，吸(xi)油(you)(you)壓(ya)(ya)(ya)油(you)(you)各(ge)一(yi)次，故稱(cheng)單(dan)作(zuo)用(yong)(yong)泵(beng)(beng)。轉(zhuan)子(zi)(zi)受到徑向液壓(ya)(ya)(ya)不平衡作(zuo)用(yong)(yong)力，故又稱(cheng)非平衡式(shi)泵(beng)(beng)，其軸承負載較大。改變(bian)定(ding)子(zi)(zi)和轉(zhuan)子(zi)(zi)間的偏心量(liang)，便可改變(bian)泵(beng)(beng)的排量(liang)，故這(zhe)種泵(beng)(beng)都是變(bian)量(liang)泵(beng)(beng)。 二(er)、雙作(zuo)用(yong)葉(xie)片(pian)泵的(de)工作(zuo)原理： ATOS葉(xie)(xie)(xie)片(pian)泵(beng)(beng)(beng)的作(zuo)用原理和(he)(he)單作(zuo)用葉(xie)(xie)(xie)片(pian)泵(beng)(beng)(beng)相似，不同之(zhi)(zhi)處(chu)只在(zai)于定子表(biao)面(mian)是(shi)(shi)由兩(liang)段(duan)長半徑圓弧、兩(liang)段(duan)短半徑圓弧和(he)(he)四段(duan)過渡曲線八個(ge)部(bu)分組成，且定子和(he)(he)轉(zhuan)(zhuan)子是(shi)(shi)同心的。在(zai)圖示轉(zhuan)(zhuan)子順時針方向旋轉(zhuan)(zhuan)的情(qing)況下，密封工作(zuo)腔的容積在(zai)左(zuo)上(shang)(shang)角(jiao)和(he)(he)右下角(jiao)處(chu)逐漸增大，為吸(xi)油(you)(you)區(qu)(qu)，在(zai)左(zuo)下角(jiao)和(he)(he)右上(shang)(shang)角(jiao)處(chu)逐漸減小，為壓油(you)(you)區(qu)(qu)；吸(xi)油(you)(you)區(qu)(qu)和(he)(he)壓油(you)(you)區(qu)(qu)之(zhi)(zhi)間有一(yi)(yi)段(duan)封油(you)(you)區(qu)(qu)把它們隔(ge)開。這種泵(beng)(beng)(beng)的轉(zhuan)(zhuan)子每轉(zhuan)(zhuan)一(yi)(yi)轉(zhuan)(zhuan)，每個(ge)密封工作(zuo)腔完成吸(xi)油(you)(you)和(he)(he)壓油(you)(you)動(dong)作(zuo)各兩(liang)次，所(suo)以(yi)稱(cheng)為雙作(zuo)用葉(xie)(xie)(xie)片(pian)泵(beng)(beng)(beng)。泵(beng)(beng)(beng)的兩(liang)個(ge)吸(xi)油(you)(you)區(qu)(qu)和(he)(he)兩(liang)個(ge)壓油(you)(you)區(qu)(qu)是(shi)(shi)徑向對稱(cheng)的，作(zuo)用在(zai)轉(zhuan)(zhuan)子上(shang)(shang)的液壓力徑向平衡，所(suo)以(yi)又稱(cheng)為平衡式葉(xie)(xie)(xie)片(pian)泵(beng)(beng)(beng)。 雙(shuang)作用葉(xie)片(pian)泵的瞬時流(liu)量是脈動的，當葉(xie)片(pian)數為(wei)4的倍(bei)數時脈動率小。為(wei)此，雙(shuang)作用葉(xie)片(pian)泵的葉(xie)片(pian)數一般都取12或16。 意大利進口ATOS葉片泵部分型號(hao)： PFE-31028/1DV
