一(yi)、單作用葉片泵的工作原理： ATOS葉(xie)片(pian)泵(beng)由轉(zhuan)(zhuan)子(zi)(zi)1、定子(zi)(zi)2、葉(xie)片(pian)3、配(pei)油(you)(you)(you)盤(pan)和端蓋等部(bu)(bu)件(jian)所(suo)組成。定子(zi)(zi)的(de)(de)(de)內(nei)表面(mian)是圓柱形孔。轉(zhuan)(zhuan)子(zi)(zi)和定子(zi)(zi)之間存在(zai)著偏心。葉(xie)片(pian)在(zai)轉(zhuan)(zhuan)子(zi)(zi)的(de)(de)(de)槽內(nei)可靈活滑動，在(zai)轉(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)動時(shi)的(de)(de)(de)離心力(li)以(yi)及通入葉(xie)片(pian)根部(bu)(bu)壓(ya)(ya)力(li)油(you)(you)(you)的(de)(de)(de)作用(yong)下(xia)，葉(xie)片(pian)頂部(bu)(bu)貼緊(jin)在(zai)定子(zi)(zi)內(nei)表面(mian)上，于是兩相鄰葉(xie)片(pian)、配(pei)油(you)(you)(you)盤(pan)、定子(zi)(zi)和轉(zhuan)(zhuan)子(zi)(zi)間便(bian)形成了一(yi)個個密(mi)封的(de)(de)(de)工(gong)作腔(qiang)。當(dang)轉(zhuan)(zhuan)子(zi)(zi)按逆時(shi)針(zhen)方向旋轉(zhuan)(zhuan)時(shi)，圖(tu)右側的(de)(de)(de)葉(xie)片(pian)向外伸出(chu)，密(mi)封工(gong)作腔(qiang)容積(ji)逐漸增(zeng)大，產(chan)生(sheng)真空(kong)，于是通過吸(xi)(xi)油(you)(you)(you)口(kou)(kou)6和配(pei)油(you)(you)(you)盤(pan)5上窗口(kou)(kou)將油(you)(you)(you)吸(xi)(xi)入。而在(zai)圖(tu)的(de)(de)(de)左側。葉(xie)片(pian)往(wang)里(li)縮(suo)進，密(mi)封腔(qiang)的(de)(de)(de)容積(ji)逐漸縮(suo)小(xiao)，密(mi)封腔(qiang)中(zhong)的(de)(de)(de)油(you)(you)(you)液(ye)經配(pei)油(you)(you)(you)盤(pan)另一(yi)窗口(kou)(kou)和壓(ya)(ya)油(you)(you)(you)口(kou)(kou)1被壓(ya)(ya)出(chu)而輸出(chu)到(dao)系統(tong)中(zhong)去。這種泵(beng)在(zai)轉(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)一(yi)轉(zhuan)(zhuan)過程中(zhong)，吸(xi)(xi)油(you)(you)(you)壓(ya)(ya)油(you)(you)(you)各一(yi)次，故(gu)稱單作用(yong)泵(beng)。轉(zhuan)(zhuan)子(zi)(zi)受到(dao)徑向液(ye)壓(ya)(ya)不平衡(heng)作用(yong)力(li)，故(gu)又(you)稱非(fei)平衡(heng)式泵(beng)，其軸承負載較大。改(gai)變定子(zi)(zi)和轉(zhuan)(zhuan)子(zi)(zi)間的(de)(de)(de)偏心量，便(bian)可改(gai)變泵(beng)的(de)(de)(de)排量，故(gu)這種泵(beng)都是變量泵(beng)。 二、雙作用葉(xie)片(pian)泵的工(gong)作原理： ATOS葉片(pian)(pian)泵(beng)的(de)(de)(de)作(zuo)(zuo)用(yong)原理(li)和(he)單作(zuo)(zuo)用(yong)葉片(pian)(pian)泵(beng)相似，不同(tong)之處只(zhi)在(zai)(zai)(zai)于定子(zi)表面是由兩(liang)(liang)段長(chang)半(ban)徑(jing)圓(yuan)(yuan)弧、兩(liang)(liang)段短半(ban)徑(jing)圓(yuan)(yuan)弧和(he)四段過渡曲線(xian)八個部分組成，且定子(zi)和(he)轉(zhuan)子(zi)是同(tong)心(xin)的(de)(de)(de)。在(zai)(zai)(zai)圖示轉(zhuan)子(zi)順(shun)時針(zhen)方向旋(xuan)轉(zhuan)的(de)(de)(de)情況下，密封(feng)(feng)工作(zuo)(zuo)腔的(de)(de)(de)容(rong)積在(zai)(zai)(zai)左上(shang)角(jiao)和(he)右下角(jiao)處逐(zhu)(zhu)漸增大，為吸(xi)油(you)(you)(you)區(qu)，在(zai)(zai)(zai)左下角(jiao)和(he)右上(shang)角(jiao)處逐(zhu)(zhu)漸減小，為壓(ya)油(you)(you)(you)區(qu)；吸(xi)油(you)(you)(you)區(qu)和(he)壓(ya)油(you)(you)(you)區(qu)之間有(you)一段封(feng)(feng)油(you)(you)(you)區(qu)把它(ta)們(men)隔開。這種泵(beng)的(de)(de)(de)轉(zhuan)子(zi)每轉(zhuan)一轉(zhuan)，每個密封(feng)(feng)工作(zuo)(zuo)腔完成吸(xi)油(you)(you)(you)和(he)壓(ya)油(you)(you)(you)動作(zuo)(zuo)各(ge)兩(liang)(liang)次，所(suo)以稱(cheng)(cheng)(cheng)為雙作(zuo)(zuo)用(yong)葉片(pian)(pian)泵(beng)。泵(beng)的(de)(de)(de)兩(liang)(liang)個吸(xi)油(you)(you)(you)區(qu)和(he)兩(liang)(liang)個壓(ya)油(you)(you)(you)區(qu)是徑(jing)向對稱(cheng)(cheng)(cheng)的(de)(de)(de)，作(zuo)(zuo)用(yong)在(zai)(zai)(zai)轉(zhuan)子(zi)上(shang)的(de)(de)(de)液壓(ya)力徑(jing)向平衡(heng)，所(suo)以又稱(cheng)(cheng)(cheng)為平衡(heng)式葉片(pian)(pian)泵(beng)。 雙作用(yong)葉(xie)片(pian)泵的(de)瞬時(shi)(shi)流量是脈動的(de)，當葉(xie)片(pian)數(shu)為4的(de)倍數(shu)時(shi)(shi)脈動率小。為此，雙作用(yong)葉(xie)片(pian)泵的(de)葉(xie)片(pian)數(shu)一般(ban)都取12或16。 意大利進口ATOS葉片泵部分(fen)型號： PFE-31028/1DV
