一、單(dan)作用(yong)葉片泵的工(gong)作原理： ATOS葉(xie)(xie)片(pian)泵由轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)1、定(ding)(ding)(ding)子(zi)(zi)2、葉(xie)(xie)片(pian)3、配(pei)油(you)(you)盤(pan)(pan)(pan)和(he)端蓋等部(bu)件所組成。定(ding)(ding)(ding)子(zi)(zi)的(de)內表面是圓柱形(xing)孔。轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)和(he)定(ding)(ding)(ding)子(zi)(zi)之間(jian)存在(zai)著偏(pian)心(xin)。葉(xie)(xie)片(pian)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)槽(cao)內可靈活滑動(dong)(dong)，在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)動(dong)(dong)時(shi)的(de)離心(xin)力以(yi)及通入葉(xie)(xie)片(pian)根部(bu)壓(ya)(ya)(ya)力油(you)(you)的(de)作用(yong)下，葉(xie)(xie)片(pian)頂(ding)部(bu)貼緊在(zai)定(ding)(ding)(ding)子(zi)(zi)內表面上，于(yu)(yu)是兩相鄰葉(xie)(xie)片(pian)、配(pei)油(you)(you)盤(pan)(pan)(pan)、定(ding)(ding)(ding)子(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)便形(xing)成了一(yi)(yi)個個密封(feng)的(de)工作腔(qiang)。當轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)按逆時(shi)針方向旋轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)時(shi)，圖右側的(de)葉(xie)(xie)片(pian)向外伸(shen)出，密封(feng)工作腔(qiang)容(rong)積逐(zhu)(zhu)漸增大(da)，產生真空，于(yu)(yu)是通過吸(xi)油(you)(you)口(kou)(kou)(kou)6和(he)配(pei)油(you)(you)盤(pan)(pan)(pan)5上窗(chuang)口(kou)(kou)(kou)將油(you)(you)吸(xi)入。而(er)在(zai)圖的(de)左側。葉(xie)(xie)片(pian)往里縮進，密封(feng)腔(qiang)的(de)容(rong)積逐(zhu)(zhu)漸縮小，密封(feng)腔(qiang)中(zhong)的(de)油(you)(you)液(ye)經配(pei)油(you)(you)盤(pan)(pan)(pan)另一(yi)(yi)窗(chuang)口(kou)(kou)(kou)和(he)壓(ya)(ya)(ya)油(you)(you)口(kou)(kou)(kou)1被壓(ya)(ya)(ya)出而(er)輸(shu)出到系統(tong)中(zhong)去。這種泵在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)一(yi)(yi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)過程中(zhong)，吸(xi)油(you)(you)壓(ya)(ya)(ya)油(you)(you)各一(yi)(yi)次(ci)，故(gu)稱單作用(yong)泵。轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)受到徑向液(ye)壓(ya)(ya)(ya)不(bu)平(ping)衡作用(yong)力，故(gu)又(you)稱非(fei)平(ping)衡式泵，其軸承(cheng)負(fu)載較大(da)。改變定(ding)(ding)(ding)子(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)的(de)偏(pian)心(xin)量，便可改變泵的(de)排量，故(gu)這種泵都是變量泵。 二(er)、雙作用葉片泵的工作原理： ATOS葉片(pian)(pian)泵(beng)的(de)(de)作(zuo)用(yong)原理和(he)單作(zuo)用(yong)葉片(pian)(pian)泵(beng)相似，不同(tong)(tong)之處只在(zai)于(yu)定(ding)子表(biao)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(fen)組成(cheng)，且定(ding)子和(he)轉(zhuan)子是(shi)同(tong)(tong)心的(de)(de)。在(zai)圖示(shi)轉(zhuan)子順時(shi)針方向旋轉(zhuan)的(de)(de)情況下，密封工(gong)作(zuo)腔的(de)(de)容積(ji)在(zai)左(zuo)上角和(he)右下角處逐漸(jian)增(zeng)大，為(wei)吸(xi)油(you)區(qu)，在(zai)左(zuo)下角和(he)右上角處逐漸(jian)減小，為(wei)壓(ya)油(you)區(qu)；吸(xi)油(you)區(qu)和(he)壓(ya)油(you)區(qu)之間有一段(duan)封油(you)區(qu)把(ba)它們隔開。這種泵(beng)的(de)(de)轉(zhuan)子每轉(zhuan)一轉(zhuan)，每個(ge)密封工(gong)作(zuo)腔完成(cheng)吸(xi)油(you)和(he)壓(ya)油(you)動作(zuo)各(ge)兩次，所以(yi)稱為(wei)雙作(zuo)用(yong)葉片(pian)(pian)泵(beng)。泵(beng)的(de)(de)兩個(ge)吸(xi)油(you)區(qu)和(he)兩個(ge)壓(ya)油(you)區(qu)是(shi)徑(jing)向對稱的(de)(de)，作(zuo)用(yong)在(zai)轉(zhuan)子上的(de)(de)液壓(ya)力徑(jing)向平(ping)衡，所以(yi)又(you)稱為(wei)平(ping)衡式葉片(pian)(pian)泵(beng)。 雙(shuang)作用葉片(pian)泵的(de)瞬時流量是脈動(dong)的(de)，當葉片(pian)數為(wei)4的(de)倍數時脈動(dong)率(lv)小(xiao)。為(wei)此，雙(shuang)作用葉片(pian)泵的(de)葉片(pian)數一般(ban)都取(qu)12或16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
