一、單作用(yong)葉片泵的工(gong)作原(yuan)理： ATOS葉片(pian)泵(beng)由轉(zhuan)子(zi)(zi)(zi)(zi)1、定(ding)子(zi)(zi)(zi)(zi)2、葉片(pian)3、配(pei)油(you)(you)(you)盤和(he)(he)端(duan)蓋(gai)等部(bu)件所組(zu)成。定(ding)子(zi)(zi)(zi)(zi)的(de)(de)內(nei)(nei)表(biao)面(mian)是圓柱形孔。轉(zhuan)子(zi)(zi)(zi)(zi)和(he)(he)定(ding)子(zi)(zi)(zi)(zi)之間(jian)存在著偏(pian)心(xin)。葉片(pian)在轉(zhuan)子(zi)(zi)(zi)(zi)的(de)(de)槽內(nei)(nei)可靈活滑動(dong)，在轉(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)動(dong)時(shi)的(de)(de)離心(xin)力(li)以及(ji)通入(ru)(ru)葉片(pian)根(gen)部(bu)壓力(li)油(you)(you)(you)的(de)(de)作(zuo)用下(xia)，葉片(pian)頂部(bu)貼(tie)緊在定(ding)子(zi)(zi)(zi)(zi)內(nei)(nei)表(biao)面(mian)上，于(yu)是兩相鄰葉片(pian)、配(pei)油(you)(you)(you)盤、定(ding)子(zi)(zi)(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)(zi)(zi)間(jian)便(bian)形成了一(yi)(yi)個(ge)個(ge)密封(feng)的(de)(de)工(gong)作(zuo)腔(qiang)。當轉(zhuan)子(zi)(zi)(zi)(zi)按逆時(shi)針方向旋轉(zhuan)時(shi)，圖(tu)右(you)側的(de)(de)葉片(pian)向外(wai)伸出，密封(feng)工(gong)作(zuo)腔(qiang)容積逐漸增大，產生真空，于(yu)是通過吸油(you)(you)(you)口(kou)6和(he)(he)配(pei)油(you)(you)(you)盤5上窗口(kou)將油(you)(you)(you)吸入(ru)(ru)。而(er)在圖(tu)的(de)(de)左側。葉片(pian)往(wang)里(li)縮進，密封(feng)腔(qiang)的(de)(de)容積逐漸縮小，密封(feng)腔(qiang)中的(de)(de)油(you)(you)(you)液(ye)(ye)經配(pei)油(you)(you)(you)盤另一(yi)(yi)窗口(kou)和(he)(he)壓油(you)(you)(you)口(kou)1被(bei)壓出而(er)輸出到系(xi)統中去。這種泵(beng)在轉(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)一(yi)(yi)轉(zhuan)過程中，吸油(you)(you)(you)壓油(you)(you)(you)各一(yi)(yi)次，故稱單(dan)作(zuo)用泵(beng)。轉(zhuan)子(zi)(zi)(zi)(zi)受(shou)到徑向液(ye)(ye)壓不(bu)平衡(heng)作(zuo)用力(li)，故又稱非平衡(heng)式泵(beng)，其軸(zhou)承(cheng)負載(zai)較大。改變定(ding)子(zi)(zi)(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)(zi)(zi)間(jian)的(de)(de)偏(pian)心(xin)量，便(bian)可改變泵(beng)的(de)(de)排量，故這種泵(beng)都是變量泵(beng)。 二(er)、雙作用葉片泵的工作原理： ATOS葉(xie)片(pian)(pian)泵(beng)(beng)的(de)作(zuo)用原理和單作(zuo)用葉(xie)片(pian)(pian)泵(beng)(beng)相似，不同(tong)之(zhi)處(chu)(chu)(chu)只在于定子(zi)(zi)(zi)(zi)表面是(shi)由兩(liang)段長半(ban)徑(jing)圓(yuan)弧、兩(liang)段短半(ban)徑(jing)圓(yuan)弧和四段過渡曲線(xian)八個(ge)部分組成(cheng)，且定子(zi)(zi)(zi)(zi)和轉(zhuan)(zhuan)子(zi)(zi)(zi)(zi)是(shi)同(tong)心的(de)。在圖示轉(zhuan)(zhuan)子(zi)(zi)(zi)(zi)順時(shi)針方向(xiang)旋轉(zhuan)(zhuan)的(de)情況下，密(mi)封(feng)工作(zuo)腔的(de)容(rong)積在左上角和右下角處(chu)(chu)(chu)逐(zhu)漸增(zeng)大，為(wei)吸(xi)油(you)(you)區，在左下角和右上角處(chu)(chu)(chu)逐(zhu)漸減(jian)小，為(wei)壓油(you)(you)區；吸(xi)油(you)(you)區和壓油(you)(you)區之(zhi)間有(you)一(yi)段封(feng)油(you)(you)區把它(ta)們隔開。這種泵(beng)(beng)的(de)轉(zhuan)(zhuan)子(zi)(zi)(zi)(zi)每轉(zhuan)(zhuan)一(yi)轉(zhuan)(zhuan)，每個(ge)密(mi)封(feng)工作(zuo)腔完成(cheng)吸(xi)油(you)(you)和壓油(you)(you)動(dong)作(zuo)各兩(liang)次，所以稱為(wei)雙作(zuo)用葉(xie)片(pian)(pian)泵(beng)(beng)。泵(beng)(beng)的(de)兩(liang)個(ge)吸(xi)油(you)(you)區和兩(liang)個(ge)壓油(you)(you)區是(shi)徑(jing)向(xiang)對稱的(de)，作(zuo)用在轉(zhuan)(zhuan)子(zi)(zi)(zi)(zi)上的(de)液壓力徑(jing)向(xiang)平(ping)衡(heng)，所以又稱為(wei)平(ping)衡(heng)式葉(xie)片(pian)(pian)泵(beng)(beng)。 雙(shuang)作(zuo)用(yong)(yong)葉(xie)片(pian)泵的(de)瞬(shun)時流量是脈(mo)動的(de)，當葉(xie)片(pian)數(shu)為(wei)4的(de)倍(bei)數(shu)時脈(mo)動率小。為(wei)此(ci)，雙(shuang)作(zuo)用(yong)(yong)葉(xie)片(pian)泵的(de)葉(xie)片(pian)數(shu)一般都(dou)取12或16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
