一、單作(zuo)用葉片泵的工作(zuo)原(yuan)理(li)： ATOS葉片(pian)泵(beng)(beng)由(you)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)1、定子(zi)(zi)(zi)(zi)(zi)2、葉片(pian)3、配油(you)(you)(you)(you)盤(pan)和(he)端(duan)蓋等部(bu)(bu)件(jian)所組成(cheng)。定子(zi)(zi)(zi)(zi)(zi)的(de)(de)內(nei)表面是(shi)圓柱形孔。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)和(he)定子(zi)(zi)(zi)(zi)(zi)之間(jian)(jian)存(cun)在(zai)著偏(pian)心。葉片(pian)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)的(de)(de)槽(cao)內(nei)可靈活(huo)滑動(dong)，在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)動(dong)時的(de)(de)離心力以及通入葉片(pian)根(gen)部(bu)(bu)壓(ya)力油(you)(you)(you)(you)的(de)(de)作(zuo)用下，葉片(pian)頂部(bu)(bu)貼緊(jin)在(zai)定子(zi)(zi)(zi)(zi)(zi)內(nei)表面上，于(yu)是(shi)兩相(xiang)鄰(lin)葉片(pian)、配油(you)(you)(you)(you)盤(pan)、定子(zi)(zi)(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)間(jian)(jian)便(bian)形成(cheng)了一(yi)個(ge)個(ge)密封(feng)(feng)的(de)(de)工作(zuo)腔。當轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)按逆時針(zhen)方向(xiang)旋轉(zhuan)(zhuan)(zhuan)時，圖右側的(de)(de)葉片(pian)向(xiang)外(wai)伸出(chu)，密封(feng)(feng)工作(zuo)腔容(rong)積逐漸增大，產生真空，于(yu)是(shi)通過(guo)吸油(you)(you)(you)(you)口(kou)6和(he)配油(you)(you)(you)(you)盤(pan)5上窗(chuang)口(kou)將油(you)(you)(you)(you)吸入。而(er)在(zai)圖的(de)(de)左(zuo)側。葉片(pian)往(wang)里(li)縮(suo)(suo)進，密封(feng)(feng)腔的(de)(de)容(rong)積逐漸縮(suo)(suo)小(xiao)，密封(feng)(feng)腔中(zhong)的(de)(de)油(you)(you)(you)(you)液經配油(you)(you)(you)(you)盤(pan)另一(yi)窗(chuang)口(kou)和(he)壓(ya)油(you)(you)(you)(you)口(kou)1被(bei)壓(ya)出(chu)而(er)輸(shu)出(chu)到系統(tong)中(zhong)去(qu)。這(zhe)種泵(beng)(beng)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)一(yi)轉(zhuan)(zhuan)(zhuan)過(guo)程中(zhong)，吸油(you)(you)(you)(you)壓(ya)油(you)(you)(you)(you)各一(yi)次，故稱單作(zuo)用泵(beng)(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)受到徑向(xiang)液壓(ya)不平衡作(zuo)用力，故又(you)稱非平衡式泵(beng)(beng)，其軸承(cheng)負載較大。改變(bian)(bian)定子(zi)(zi)(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)(zi)間(jian)(jian)的(de)(de)偏(pian)心量(liang)，便(bian)可改變(bian)(bian)泵(beng)(beng)的(de)(de)排量(liang)，故這(zhe)種泵(beng)(beng)都是(shi)變(bian)(bian)量(liang)泵(beng)(beng)。 二、雙(shuang)作用葉片泵(beng)的工作原(yuan)理： ATOS葉(xie)片(pian)(pian)泵(beng)(beng)(beng)的(de)作(zuo)用原理和(he)單作(zuo)用葉(xie)片(pian)(pian)泵(beng)(beng)(beng)相似，不同(tong)之處只在(zai)于定(ding)子(zi)表面是(shi)由兩(liang)段長半徑圓弧(hu)、兩(liang)段短半徑圓弧(hu)和(he)四(si)段過渡曲線八個(ge)部分(fen)組(zu)成，且定(ding)子(zi)和(he)轉子(zi)是(shi)同(tong)心(xin)的(de)。在(zai)圖示(shi)轉子(zi)順時針方(fang)向(xiang)旋(xuan)轉的(de)情況下，密(mi)封工作(zuo)腔的(de)容(rong)積在(zai)左(zuo)上角和(he)右(you)下角處逐漸(jian)(jian)增大，為(wei)吸(xi)油(you)區，在(zai)左(zuo)下角和(he)右(you)上角處逐漸(jian)(jian)減小，為(wei)壓(ya)(ya)油(you)區；吸(xi)油(you)區和(he)壓(ya)(ya)油(you)區之間有一段封油(you)區把它們隔開。這(zhe)種泵(beng)(beng)(beng)的(de)轉子(zi)每轉一轉，每個(ge)密(mi)封工作(zuo)腔完成吸(xi)油(you)和(he)壓(ya)(ya)油(you)動(dong)作(zuo)各兩(liang)次，所以稱(cheng)為(wei)雙作(zuo)用葉(xie)片(pian)(pian)泵(beng)(beng)(beng)。泵(beng)(beng)(beng)的(de)兩(liang)個(ge)吸(xi)油(you)區和(he)兩(liang)個(ge)壓(ya)(ya)油(you)區是(shi)徑向(xiang)對稱(cheng)的(de)，作(zuo)用在(zai)轉子(zi)上的(de)液(ye)壓(ya)(ya)力徑向(xiang)平衡，所以又稱(cheng)為(wei)平衡式(shi)葉(xie)片(pian)(pian)泵(beng)(beng)(beng)。 雙作用葉(xie)片(pian)泵(beng)的(de)瞬時(shi)流量(liang)是脈動的(de)，當葉(xie)片(pian)數為(wei)4的(de)倍數時(shi)脈動率(lv)小。為(wei)此，雙作用葉(xie)片(pian)泵(beng)的(de)葉(xie)片(pian)數一般都取12或16。 意大利進口ATOS葉片泵部分(fen)型號： PFE-31028/1DV
