一、單(dan)作用葉片泵的工作原理： ATOS葉(xie)片(pian)(pian)泵(beng)(beng)(beng)由轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)1、定(ding)(ding)子(zi)(zi)2、葉(xie)片(pian)(pian)3、配(pei)(pei)油(you)(you)(you)(you)盤(pan)(pan)和端蓋等部件所組(zu)成(cheng)。定(ding)(ding)子(zi)(zi)的(de)(de)(de)內表面是圓(yuan)柱形孔。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)和定(ding)(ding)子(zi)(zi)之(zhi)間(jian)存(cun)在(zai)著偏(pian)心(xin)。葉(xie)片(pian)(pian)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)(de)槽內可靈活滑動，在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)動時的(de)(de)(de)離心(xin)力以及通(tong)入葉(xie)片(pian)(pian)根部壓(ya)力油(you)(you)(you)(you)的(de)(de)(de)作用(yong)下，葉(xie)片(pian)(pian)頂(ding)部貼(tie)緊在(zai)定(ding)(ding)子(zi)(zi)內表面上，于是兩(liang)相鄰葉(xie)片(pian)(pian)、配(pei)(pei)油(you)(you)(you)(you)盤(pan)(pan)、定(ding)(ding)子(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)便形成(cheng)了(le)一(yi)(yi)個(ge)個(ge)密(mi)封(feng)的(de)(de)(de)工(gong)作腔。當(dang)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)按逆時針(zhen)方向(xiang)旋轉(zhuan)(zhuan)(zhuan)(zhuan)時，圖(tu)右側的(de)(de)(de)葉(xie)片(pian)(pian)向(xiang)外伸出，密(mi)封(feng)工(gong)作腔容積逐漸增大(da)，產生真空，于是通(tong)過吸油(you)(you)(you)(you)口(kou)6和配(pei)(pei)油(you)(you)(you)(you)盤(pan)(pan)5上窗口(kou)將油(you)(you)(you)(you)吸入。而(er)在(zai)圖(tu)的(de)(de)(de)左側。葉(xie)片(pian)(pian)往里縮進，密(mi)封(feng)腔的(de)(de)(de)容積逐漸縮小，密(mi)封(feng)腔中(zhong)的(de)(de)(de)油(you)(you)(you)(you)液經配(pei)(pei)油(you)(you)(you)(you)盤(pan)(pan)另一(yi)(yi)窗口(kou)和壓(ya)油(you)(you)(you)(you)口(kou)1被壓(ya)出而(er)輸出到系統中(zhong)去。這種泵(beng)(beng)(beng)在(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)一(yi)(yi)轉(zhuan)(zhuan)(zhuan)(zhuan)過程(cheng)中(zhong)，吸油(you)(you)(you)(you)壓(ya)油(you)(you)(you)(you)各一(yi)(yi)次(ci)，故稱單作用(yong)泵(beng)(beng)(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)受到徑向(xiang)液壓(ya)不平衡作用(yong)力，故又(you)稱非平衡式泵(beng)(beng)(beng)，其軸(zhou)承負載(zai)較大(da)。改變定(ding)(ding)子(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)間(jian)的(de)(de)(de)偏(pian)心(xin)量，便可改變泵(beng)(beng)(beng)的(de)(de)(de)排量，故這種泵(beng)(beng)(beng)都(dou)是變量泵(beng)(beng)(beng)。 二、雙作用葉片泵的工作原理： ATOS葉(xie)片泵的(de)作用原理和(he)(he)單作用葉(xie)片泵相(xiang)似，不同之處只在于定子表面(mian)是(shi)(shi)由兩段長(chang)半(ban)徑圓弧、兩段短(duan)半(ban)徑圓弧和(he)(he)四段過渡曲線八(ba)個部分組成，且定子和(he)(he)轉(zhuan)子是(shi)(shi)同心的(de)。在圖示(shi)轉(zhuan)子順(shun)時針方向(xiang)旋轉(zhuan)的(de)情況下，密封工(gong)(gong)作腔的(de)容積在左上角(jiao)(jiao)和(he)(he)右(you)(you)下角(jiao)(jiao)處逐漸增(zeng)大(da)，為(wei)(wei)吸(xi)油(you)(you)區，在左下角(jiao)(jiao)和(he)(he)右(you)(you)上角(jiao)(jiao)處逐漸減(jian)小，為(wei)(wei)壓油(you)(you)區；吸(xi)油(you)(you)區和(he)(he)壓油(you)(you)區之間(jian)有(you)一段封油(you)(you)區把(ba)它們(men)隔開。這種泵的(de)轉(zhuan)子每(mei)轉(zhuan)一轉(zhuan)，每(mei)個密封工(gong)(gong)作腔完成吸(xi)油(you)(you)和(he)(he)壓油(you)(you)動作各兩次，所(suo)以(yi)稱(cheng)(cheng)為(wei)(wei)雙作用葉(xie)片泵。泵的(de)兩個吸(xi)油(you)(you)區和(he)(he)兩個壓油(you)(you)區是(shi)(shi)徑向(xiang)對稱(cheng)(cheng)的(de)，作用在轉(zhuan)子上的(de)液壓力徑向(xiang)平(ping)衡，所(suo)以(yi)又稱(cheng)(cheng)為(wei)(wei)平(ping)衡式(shi)葉(xie)片泵。 雙作用葉(xie)(xie)片(pian)泵的瞬時流(liu)量(liang)是脈動的，當葉(xie)(xie)片(pian)數為4的倍數時脈動率(lv)小。為此(ci)，雙作用葉(xie)(xie)片(pian)泵的葉(xie)(xie)片(pian)數一般都取(qu)12或16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
