一、單作用葉片泵的工(gong)作原(yuan)理(li)： ATOS葉(xie)(xie)片(pian)(pian)泵(beng)由轉(zhuan)子(zi)(zi)1、定子(zi)(zi)2、葉(xie)(xie)片(pian)(pian)3、配油(you)盤(pan)和端蓋等部(bu)(bu)件所組成(cheng)。定子(zi)(zi)的(de)(de)內(nei)表(biao)面(mian)是圓柱形孔(kong)。轉(zhuan)子(zi)(zi)和定子(zi)(zi)之(zhi)間(jian)(jian)存在(zai)(zai)著偏(pian)心。葉(xie)(xie)片(pian)(pian)在(zai)(zai)轉(zhuan)子(zi)(zi)的(de)(de)槽(cao)內(nei)可靈活滑動，在(zai)(zai)轉(zhuan)子(zi)(zi)轉(zhuan)動時的(de)(de)離心力(li)(li)以及通(tong)入葉(xie)(xie)片(pian)(pian)根部(bu)(bu)壓(ya)力(li)(li)油(you)的(de)(de)作用下，葉(xie)(xie)片(pian)(pian)頂部(bu)(bu)貼緊在(zai)(zai)定子(zi)(zi)內(nei)表(biao)面(mian)上，于(yu)是兩(liang)相(xiang)鄰(lin)葉(xie)(xie)片(pian)(pian)、配油(you)盤(pan)、定子(zi)(zi)和轉(zhuan)子(zi)(zi)間(jian)(jian)便形成(cheng)了一(yi)個(ge)個(ge)密(mi)封(feng)的(de)(de)工作腔。當轉(zhuan)子(zi)(zi)按逆時針方向(xiang)旋轉(zhuan)時，圖右側的(de)(de)葉(xie)(xie)片(pian)(pian)向(xiang)外伸出，密(mi)封(feng)工作腔容(rong)積逐漸(jian)增大，產生真空，于(yu)是通(tong)過(guo)吸(xi)油(you)口6和配油(you)盤(pan)5上窗(chuang)口將油(you)吸(xi)入。而(er)(er)在(zai)(zai)圖的(de)(de)左側。葉(xie)(xie)片(pian)(pian)往里(li)縮進(jin)，密(mi)封(feng)腔的(de)(de)容(rong)積逐漸(jian)縮小，密(mi)封(feng)腔中的(de)(de)油(you)液經配油(you)盤(pan)另一(yi)窗(chuang)口和壓(ya)油(you)口1被壓(ya)出而(er)(er)輸(shu)出到系統中去。這種泵(beng)在(zai)(zai)轉(zhuan)子(zi)(zi)轉(zhuan)一(yi)轉(zhuan)過(guo)程(cheng)中，吸(xi)油(you)壓(ya)油(you)各一(yi)次，故(gu)稱單作用泵(beng)。轉(zhuan)子(zi)(zi)受到徑(jing)向(xiang)液壓(ya)不平(ping)衡作用力(li)(li)，故(gu)又(you)稱非平(ping)衡式泵(beng)，其軸承負載較大。改變(bian)(bian)定子(zi)(zi)和轉(zhuan)子(zi)(zi)間(jian)(jian)的(de)(de)偏(pian)心量，便可改變(bian)(bian)泵(beng)的(de)(de)排量，故(gu)這種泵(beng)都是變(bian)(bian)量泵(beng)。 二、雙作用葉片泵的工(gong)作原理(li)： ATOS葉(xie)片(pian)泵的(de)作用原理(li)和單(dan)作用葉(xie)片(pian)泵相(xiang)似(si)，不同(tong)之處(chu)只在(zai)(zai)于定子表面是(shi)由兩(liang)(liang)段(duan)(duan)長半徑圓弧(hu)、兩(liang)(liang)段(duan)(duan)短半徑圓弧(hu)和四(si)段(duan)(duan)過渡曲線八(ba)個(ge)部分(fen)組(zu)成，且定子和轉(zhuan)(zhuan)(zhuan)子是(shi)同(tong)心的(de)。在(zai)(zai)圖示轉(zhuan)(zhuan)(zhuan)子順(shun)時針方向(xiang)旋(xuan)轉(zhuan)(zhuan)(zhuan)的(de)情況下(xia)，密(mi)封工作腔的(de)容積在(zai)(zai)左上(shang)(shang)角(jiao)和右下(xia)角(jiao)處(chu)逐漸增大，為吸(xi)油(you)(you)區(qu)(qu)，在(zai)(zai)左下(xia)角(jiao)和右上(shang)(shang)角(jiao)處(chu)逐漸減小，為壓(ya)(ya)油(you)(you)區(qu)(qu)；吸(xi)油(you)(you)區(qu)(qu)和壓(ya)(ya)油(you)(you)區(qu)(qu)之間有一段(duan)(duan)封油(you)(you)區(qu)(qu)把它們隔開。這種泵的(de)轉(zhuan)(zhuan)(zhuan)子每(mei)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)，每(mei)個(ge)密(mi)封工作腔完成吸(xi)油(you)(you)和壓(ya)(ya)油(you)(you)動作各(ge)兩(liang)(liang)次，所以稱(cheng)為雙作用葉(xie)片(pian)泵。泵的(de)兩(liang)(liang)個(ge)吸(xi)油(you)(you)區(qu)(qu)和兩(liang)(liang)個(ge)壓(ya)(ya)油(you)(you)區(qu)(qu)是(shi)徑向(xiang)對稱(cheng)的(de)，作用在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子上(shang)(shang)的(de)液壓(ya)(ya)力徑向(xiang)平(ping)(ping)衡(heng)，所以又稱(cheng)為平(ping)(ping)衡(heng)式葉(xie)片(pian)泵。 雙作(zuo)用葉(xie)(xie)片(pian)(pian)泵(beng)的(de)(de)瞬時流量是(shi)脈動(dong)的(de)(de)，當葉(xie)(xie)片(pian)(pian)數(shu)(shu)為(wei)4的(de)(de)倍數(shu)(shu)時脈動(dong)率小。為(wei)此，雙作(zuo)用葉(xie)(xie)片(pian)(pian)泵(beng)的(de)(de)葉(xie)(xie)片(pian)(pian)數(shu)(shu)一(yi)般都(dou)取12或(huo)16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
