一、單作用葉片泵的工作原理： ATOS葉(xie)(xie)片(pian)(pian)泵(beng)由轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)1、定(ding)(ding)(ding)子(zi)2、葉(xie)(xie)片(pian)(pian)3、配油(you)(you)盤(pan)和端蓋等(deng)部件所組成(cheng)。定(ding)(ding)(ding)子(zi)的內(nei)表面是(shi)(shi)圓柱形孔。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)和定(ding)(ding)(ding)子(zi)之間(jian)存在(zai)(zai)著偏心(xin)(xin)。葉(xie)(xie)片(pian)(pian)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)的槽(cao)內(nei)可靈活滑動，在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)動時的離心(xin)(xin)力(li)以及通(tong)入(ru)葉(xie)(xie)片(pian)(pian)根(gen)部壓(ya)力(li)油(you)(you)的作(zuo)用下，葉(xie)(xie)片(pian)(pian)頂部貼(tie)緊在(zai)(zai)定(ding)(ding)(ding)子(zi)內(nei)表面上，于是(shi)(shi)兩相鄰葉(xie)(xie)片(pian)(pian)、配油(you)(you)盤(pan)、定(ding)(ding)(ding)子(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)間(jian)便(bian)形成(cheng)了一個個密封(feng)(feng)的工作(zuo)腔。當轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)按逆時針方向旋轉(zhuan)(zhuan)(zhuan)(zhuan)時，圖(tu)右側的葉(xie)(xie)片(pian)(pian)向外伸出(chu)，密封(feng)(feng)工作(zuo)腔容積逐漸(jian)增大，產生真空，于是(shi)(shi)通(tong)過吸油(you)(you)口(kou)6和配油(you)(you)盤(pan)5上窗口(kou)將油(you)(you)吸入(ru)。而在(zai)(zai)圖(tu)的左側。葉(xie)(xie)片(pian)(pian)往(wang)里縮進，密封(feng)(feng)腔的容積逐漸(jian)縮小(xiao)，密封(feng)(feng)腔中的油(you)(you)液(ye)經(jing)配油(you)(you)盤(pan)另一窗口(kou)和壓(ya)油(you)(you)口(kou)1被壓(ya)出(chu)而輸出(chu)到系統(tong)中去。這(zhe)種(zhong)(zhong)泵(beng)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)(zhuan)過程中，吸油(you)(you)壓(ya)油(you)(you)各一次，故(gu)稱單(dan)作(zuo)用泵(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)受到徑向液(ye)壓(ya)不平(ping)(ping)衡作(zuo)用力(li)，故(gu)又稱非平(ping)(ping)衡式泵(beng)，其軸承負載較大。改變(bian)定(ding)(ding)(ding)子(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)間(jian)的偏心(xin)(xin)量，便(bian)可改變(bian)泵(beng)的排量，故(gu)這(zhe)種(zhong)(zhong)泵(beng)都是(shi)(shi)變(bian)量泵(beng)。 二、雙作用(yong)葉(xie)片泵的工作原理(li)： ATOS葉(xie)片泵的(de)(de)作(zuo)(zuo)(zuo)用原理和(he)單作(zuo)(zuo)(zuo)用葉(xie)片泵相(xiang)似，不同之處(chu)只在(zai)(zai)(zai)于(yu)定(ding)子(zi)(zi)表面是(shi)由兩(liang)段(duan)長半(ban)徑(jing)圓(yuan)弧、兩(liang)段(duan)短半(ban)徑(jing)圓(yuan)弧和(he)四段(duan)過渡曲線八個(ge)(ge)部分(fen)組成，且(qie)定(ding)子(zi)(zi)和(he)轉子(zi)(zi)是(shi)同心的(de)(de)。在(zai)(zai)(zai)圖示轉子(zi)(zi)順時針方(fang)向(xiang)旋(xuan)轉的(de)(de)情況(kuang)下(xia)，密封(feng)工作(zuo)(zuo)(zuo)腔(qiang)的(de)(de)容積在(zai)(zai)(zai)左(zuo)上角和(he)右(you)下(xia)角處(chu)逐漸增大，為吸油(you)區(qu)(qu)，在(zai)(zai)(zai)左(zuo)下(xia)角和(he)右(you)上角處(chu)逐漸減小，為壓(ya)油(you)區(qu)(qu)；吸油(you)區(qu)(qu)和(he)壓(ya)油(you)區(qu)(qu)之間有一段(duan)封(feng)油(you)區(qu)(qu)把它們隔開。這種泵的(de)(de)轉子(zi)(zi)每(mei)轉一轉，每(mei)個(ge)(ge)密封(feng)工作(zuo)(zuo)(zuo)腔(qiang)完成吸油(you)和(he)壓(ya)油(you)動作(zuo)(zuo)(zuo)各兩(liang)次，所以(yi)稱(cheng)(cheng)為雙作(zuo)(zuo)(zuo)用葉(xie)片泵。泵的(de)(de)兩(liang)個(ge)(ge)吸油(you)區(qu)(qu)和(he)兩(liang)個(ge)(ge)壓(ya)油(you)區(qu)(qu)是(shi)徑(jing)向(xiang)對(dui)稱(cheng)(cheng)的(de)(de)，作(zuo)(zuo)(zuo)用在(zai)(zai)(zai)轉子(zi)(zi)上的(de)(de)液壓(ya)力徑(jing)向(xiang)平衡，所以(yi)又稱(cheng)(cheng)為平衡式葉(xie)片泵。 雙作用(yong)葉(xie)片泵(beng)的(de)瞬時流量是脈動(dong)(dong)的(de)，當葉(xie)片數(shu)為4的(de)倍數(shu)時脈動(dong)(dong)率(lv)小。為此(ci)，雙作用(yong)葉(xie)片泵(beng)的(de)葉(xie)片數(shu)一般(ban)都取12或16。 意大利進口ATOS葉片泵部分型號(hao)： PFE-31028/1DV
