一、單作用葉(xie)片泵的工作原理： ATOS葉(xie)片(pian)泵(beng)由(you)轉(zhuan)(zhuan)(zhuan)子(zi)1、定(ding)(ding)子(zi)2、葉(xie)片(pian)3、配(pei)油(you)(you)盤和(he)端蓋(gai)等部(bu)件所組(zu)成。定(ding)(ding)子(zi)的(de)內表面是(shi)(shi)圓(yuan)柱形孔。轉(zhuan)(zhuan)(zhuan)子(zi)和(he)定(ding)(ding)子(zi)之間(jian)存在(zai)著偏心(xin)。葉(xie)片(pian)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)的(de)槽內可(ke)靈活滑動，在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)動時的(de)離心(xin)力(li)以及通入(ru)(ru)葉(xie)片(pian)根部(bu)壓力(li)油(you)(you)的(de)作用下，葉(xie)片(pian)頂部(bu)貼緊(jin)在(zai)定(ding)(ding)子(zi)內表面上(shang)，于(yu)是(shi)(shi)兩相(xiang)鄰(lin)葉(xie)片(pian)、配(pei)油(you)(you)盤、定(ding)(ding)子(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)便形成了一個個密(mi)封(feng)的(de)工作腔(qiang)(qiang)。當轉(zhuan)(zhuan)(zhuan)子(zi)按逆時針方向旋轉(zhuan)(zhuan)(zhuan)時，圖(tu)(tu)右側的(de)葉(xie)片(pian)向外伸(shen)出，密(mi)封(feng)工作腔(qiang)(qiang)容積逐漸增大(da)，產生真空，于(yu)是(shi)(shi)通過吸油(you)(you)口(kou)6和(he)配(pei)油(you)(you)盤5上(shang)窗口(kou)將(jiang)油(you)(you)吸入(ru)(ru)。而在(zai)圖(tu)(tu)的(de)左側。葉(xie)片(pian)往(wang)里(li)縮進，密(mi)封(feng)腔(qiang)(qiang)的(de)容積逐漸縮小(xiao)，密(mi)封(feng)腔(qiang)(qiang)中(zhong)(zhong)的(de)油(you)(you)液經配(pei)油(you)(you)盤另一窗口(kou)和(he)壓油(you)(you)口(kou)1被壓出而輸出到系統(tong)中(zhong)(zhong)去。這種泵(beng)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)過程中(zhong)(zhong)，吸油(you)(you)壓油(you)(you)各一次，故稱單作用泵(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)受到徑向液壓不平(ping)衡作用力(li)，故又稱非平(ping)衡式泵(beng)，其軸承負載較大(da)。改(gai)變定(ding)(ding)子(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)的(de)偏心(xin)量，便可(ke)改(gai)變泵(beng)的(de)排量，故這種泵(beng)都是(shi)(shi)變量泵(beng)。 二、雙作用葉片泵(beng)的(de)工(gong)作原理： ATOS葉片(pian)泵(beng)(beng)的(de)作(zuo)用(yong)原理(li)和(he)(he)單作(zuo)用(yong)葉片(pian)泵(beng)(beng)相似，不同(tong)(tong)之處(chu)只在于定(ding)子(zi)(zi)表面是由兩(liang)(liang)段(duan)長半徑圓弧(hu)、兩(liang)(liang)段(duan)短半徑圓弧(hu)和(he)(he)四段(duan)過渡曲線八(ba)個部(bu)分組成，且定(ding)子(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)是同(tong)(tong)心(xin)的(de)。在圖示轉(zhuan)子(zi)(zi)順時針(zhen)方向(xiang)(xiang)旋轉(zhuan)的(de)情況下，密封(feng)(feng)工(gong)作(zuo)腔的(de)容積在左上角和(he)(he)右下角處(chu)逐(zhu)漸增大，為(wei)(wei)吸(xi)(xi)油(you)(you)區(qu)(qu)(qu)，在左下角和(he)(he)右上角處(chu)逐(zhu)漸減小(xiao)，為(wei)(wei)壓(ya)油(you)(you)區(qu)(qu)(qu)；吸(xi)(xi)油(you)(you)區(qu)(qu)(qu)和(he)(he)壓(ya)油(you)(you)區(qu)(qu)(qu)之間有一(yi)段(duan)封(feng)(feng)油(you)(you)區(qu)(qu)(qu)把(ba)它們隔開。這種泵(beng)(beng)的(de)轉(zhuan)子(zi)(zi)每(mei)轉(zhuan)一(yi)轉(zhuan)，每(mei)個密封(feng)(feng)工(gong)作(zuo)腔完成吸(xi)(xi)油(you)(you)和(he)(he)壓(ya)油(you)(you)動(dong)作(zuo)各(ge)兩(liang)(liang)次，所以稱為(wei)(wei)雙作(zuo)用(yong)葉片(pian)泵(beng)(beng)。泵(beng)(beng)的(de)兩(liang)(liang)個吸(xi)(xi)油(you)(you)區(qu)(qu)(qu)和(he)(he)兩(liang)(liang)個壓(ya)油(you)(you)區(qu)(qu)(qu)是徑向(xiang)(xiang)對稱的(de)，作(zuo)用(yong)在轉(zhuan)子(zi)(zi)上的(de)液壓(ya)力徑向(xiang)(xiang)平(ping)衡，所以又(you)稱為(wei)(wei)平(ping)衡式(shi)葉片(pian)泵(beng)(beng)。 雙作(zuo)用(yong)葉(xie)片(pian)(pian)泵的(de)瞬時流量是脈動(dong)的(de)，當葉(xie)片(pian)(pian)數(shu)為(wei)4的(de)倍數(shu)時脈動(dong)率小。為(wei)此，雙作(zuo)用(yong)葉(xie)片(pian)(pian)泵的(de)葉(xie)片(pian)(pian)數(shu)一般都取12或(huo)16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
