一、單作用葉(xie)片泵的工(gong)作原(yuan)理： ATOS葉(xie)片(pian)(pian)泵(beng)(beng)由轉(zhuan)(zhuan)(zhuan)子(zi)1、定(ding)(ding)(ding)子(zi)2、葉(xie)片(pian)(pian)3、配(pei)(pei)(pei)油(you)(you)盤(pan)和(he)端(duan)蓋等部(bu)件所組成。定(ding)(ding)(ding)子(zi)的內(nei)表(biao)面是(shi)(shi)圓柱(zhu)形(xing)孔。轉(zhuan)(zhuan)(zhuan)子(zi)和(he)定(ding)(ding)(ding)子(zi)之間(jian)(jian)存在著偏心(xin)。葉(xie)片(pian)(pian)在轉(zhuan)(zhuan)(zhuan)子(zi)的槽內(nei)可(ke)靈(ling)活滑動(dong)，在轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)動(dong)時(shi)的離心(xin)力以(yi)及通入(ru)葉(xie)片(pian)(pian)根部(bu)壓力油(you)(you)的作(zuo)用(yong)(yong)下，葉(xie)片(pian)(pian)頂部(bu)貼緊(jin)在定(ding)(ding)(ding)子(zi)內(nei)表(biao)面上，于(yu)是(shi)(shi)兩相(xiang)鄰(lin)葉(xie)片(pian)(pian)、配(pei)(pei)(pei)油(you)(you)盤(pan)、定(ding)(ding)(ding)子(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)(jian)便(bian)形(xing)成了一個個密封(feng)的工作(zuo)腔。當轉(zhuan)(zhuan)(zhuan)子(zi)按逆(ni)時(shi)針方向旋轉(zhuan)(zhuan)(zhuan)時(shi)，圖右側(ce)(ce)的葉(xie)片(pian)(pian)向外伸(shen)出(chu)，密封(feng)工作(zuo)腔容積逐(zhu)漸增大，產(chan)生真空，于(yu)是(shi)(shi)通過吸油(you)(you)口(kou)6和(he)配(pei)(pei)(pei)油(you)(you)盤(pan)5上窗口(kou)將(jiang)油(you)(you)吸入(ru)。而在圖的左側(ce)(ce)。葉(xie)片(pian)(pian)往里縮(suo)進(jin)，密封(feng)腔的容積逐(zhu)漸縮(suo)小，密封(feng)腔中的油(you)(you)液經配(pei)(pei)(pei)油(you)(you)盤(pan)另一窗口(kou)和(he)壓油(you)(you)口(kou)1被壓出(chu)而輸出(chu)到系統中去。這(zhe)種泵(beng)(beng)在轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)過程中，吸油(you)(you)壓油(you)(you)各一次，故(gu)稱單作(zuo)用(yong)(yong)泵(beng)(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)受到徑(jing)向液壓不(bu)平衡作(zuo)用(yong)(yong)力，故(gu)又稱非平衡式泵(beng)(beng)，其(qi)軸(zhou)承負載(zai)較(jiao)大。改變(bian)定(ding)(ding)(ding)子(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)(jian)的偏心(xin)量，便(bian)可(ke)改變(bian)泵(beng)(beng)的排量，故(gu)這(zhe)種泵(beng)(beng)都(dou)是(shi)(shi)變(bian)量泵(beng)(beng)。 二(er)、雙作用(yong)葉(xie)片泵的工作原理： ATOS葉(xie)(xie)(xie)(xie)片(pian)泵的(de)作(zuo)(zuo)用原理和(he)(he)(he)單(dan)作(zuo)(zuo)用葉(xie)(xie)(xie)(xie)片(pian)泵相似，不(bu)同(tong)之處(chu)只在(zai)于定子(zi)表面是由兩(liang)(liang)(liang)段(duan)長(chang)半徑(jing)(jing)圓弧、兩(liang)(liang)(liang)段(duan)短半徑(jing)(jing)圓弧和(he)(he)(he)四段(duan)過(guo)渡(du)曲(qu)線八個(ge)部(bu)分組成，且定子(zi)和(he)(he)(he)轉(zhuan)(zhuan)子(zi)是同(tong)心的(de)。在(zai)圖示(shi)轉(zhuan)(zhuan)子(zi)順時針方向(xiang)旋轉(zhuan)(zhuan)的(de)情況下(xia)(xia)，密封工作(zuo)(zuo)腔的(de)容積在(zai)左上角和(he)(he)(he)右下(xia)(xia)角處(chu)逐(zhu)漸增大，為吸油(you)(you)區(qu)，在(zai)左下(xia)(xia)角和(he)(he)(he)右上角處(chu)逐(zhu)漸減小，為壓(ya)油(you)(you)區(qu)；吸油(you)(you)區(qu)和(he)(he)(he)壓(ya)油(you)(you)區(qu)之間有一段(duan)封油(you)(you)區(qu)把它們隔(ge)開。這種(zhong)泵的(de)轉(zhuan)(zhuan)子(zi)每轉(zhuan)(zhuan)一轉(zhuan)(zhuan)，每個(ge)密封工作(zuo)(zuo)腔完成吸油(you)(you)和(he)(he)(he)壓(ya)油(you)(you)動(dong)作(zuo)(zuo)各兩(liang)(liang)(liang)次，所以(yi)稱為雙(shuang)作(zuo)(zuo)用葉(xie)(xie)(xie)(xie)片(pian)泵。泵的(de)兩(liang)(liang)(liang)個(ge)吸油(you)(you)區(qu)和(he)(he)(he)兩(liang)(liang)(liang)個(ge)壓(ya)油(you)(you)區(qu)是徑(jing)(jing)向(xiang)對稱的(de)，作(zuo)(zuo)用在(zai)轉(zhuan)(zhuan)子(zi)上的(de)液壓(ya)力徑(jing)(jing)向(xiang)平衡，所以(yi)又稱為平衡式葉(xie)(xie)(xie)(xie)片(pian)泵。 雙作(zuo)用葉(xie)片(pian)泵的(de)(de)瞬時流量(liang)是脈(mo)動的(de)(de)，當葉(xie)片(pian)數(shu)為(wei)4的(de)(de)倍(bei)數(shu)時脈(mo)動率小。為(wei)此，雙作(zuo)用葉(xie)片(pian)泵的(de)(de)葉(xie)片(pian)數(shu)一(yi)般都取12或16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
