一、單(dan)作用葉片(pian)泵(beng)的(de)工作原理： ATOS葉(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)由轉(zhuan)子(zi)(zi)(zi)(zi)1、定(ding)子(zi)(zi)(zi)(zi)2、葉(xie)(xie)片(pian)(pian)(pian)3、配油(you)(you)(you)盤(pan)和(he)(he)(he)端蓋等部(bu)(bu)件所(suo)組(zu)成。定(ding)子(zi)(zi)(zi)(zi)的(de)(de)內(nei)表面是(shi)圓柱形孔。轉(zhuan)子(zi)(zi)(zi)(zi)和(he)(he)(he)定(ding)子(zi)(zi)(zi)(zi)之間存在(zai)(zai)著偏(pian)心。葉(xie)(xie)片(pian)(pian)(pian)在(zai)(zai)轉(zhuan)子(zi)(zi)(zi)(zi)的(de)(de)槽內(nei)可靈(ling)活滑動(dong)，在(zai)(zai)轉(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)動(dong)時(shi)的(de)(de)離心力以(yi)及通入葉(xie)(xie)片(pian)(pian)(pian)根部(bu)(bu)壓(ya)力油(you)(you)(you)的(de)(de)作(zuo)(zuo)用下，葉(xie)(xie)片(pian)(pian)(pian)頂(ding)部(bu)(bu)貼緊在(zai)(zai)定(ding)子(zi)(zi)(zi)(zi)內(nei)表面上(shang)，于是(shi)兩(liang)相鄰葉(xie)(xie)片(pian)(pian)(pian)、配油(you)(you)(you)盤(pan)、定(ding)子(zi)(zi)(zi)(zi)和(he)(he)(he)轉(zhuan)子(zi)(zi)(zi)(zi)間便形成了一個(ge)個(ge)密(mi)封的(de)(de)工作(zuo)(zuo)腔(qiang)。當轉(zhuan)子(zi)(zi)(zi)(zi)按逆(ni)時(shi)針方向(xiang)旋轉(zhuan)時(shi)，圖(tu)(tu)右側的(de)(de)葉(xie)(xie)片(pian)(pian)(pian)向(xiang)外伸出(chu)，密(mi)封工作(zuo)(zuo)腔(qiang)容積逐漸增大(da)，產(chan)生真空，于是(shi)通過吸油(you)(you)(you)口(kou)6和(he)(he)(he)配油(you)(you)(you)盤(pan)5上(shang)窗(chuang)口(kou)將(jiang)油(you)(you)(you)吸入。而在(zai)(zai)圖(tu)(tu)的(de)(de)左側。葉(xie)(xie)片(pian)(pian)(pian)往里縮進，密(mi)封腔(qiang)的(de)(de)容積逐漸縮小，密(mi)封腔(qiang)中(zhong)(zhong)(zhong)的(de)(de)油(you)(you)(you)液(ye)經配油(you)(you)(you)盤(pan)另一窗(chuang)口(kou)和(he)(he)(he)壓(ya)油(you)(you)(you)口(kou)1被(bei)壓(ya)出(chu)而輸出(chu)到(dao)系統中(zhong)(zhong)(zhong)去。這(zhe)種泵(beng)(beng)(beng)在(zai)(zai)轉(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)一轉(zhuan)過程中(zhong)(zhong)(zhong)，吸油(you)(you)(you)壓(ya)油(you)(you)(you)各一次，故稱(cheng)單作(zuo)(zuo)用泵(beng)(beng)(beng)。轉(zhuan)子(zi)(zi)(zi)(zi)受到(dao)徑向(xiang)液(ye)壓(ya)不平衡作(zuo)(zuo)用力，故又稱(cheng)非平衡式泵(beng)(beng)(beng)，其軸承負(fu)載較大(da)。改變(bian)定(ding)子(zi)(zi)(zi)(zi)和(he)(he)(he)轉(zhuan)子(zi)(zi)(zi)(zi)間的(de)(de)偏(pian)心量，便可改變(bian)泵(beng)(beng)(beng)的(de)(de)排量，故這(zhe)種泵(beng)(beng)(beng)都是(shi)變(bian)量泵(beng)(beng)(beng)。 二、雙作(zuo)用葉片泵(beng)的工作(zuo)原(yuan)理： ATOS葉片(pian)(pian)泵(beng)(beng)的作(zuo)(zuo)用(yong)(yong)原理(li)和(he)(he)(he)單作(zuo)(zuo)用(yong)(yong)葉片(pian)(pian)泵(beng)(beng)相似，不同之(zhi)處只在于定(ding)子(zi)(zi)(zi)表面是(shi)由兩(liang)(liang)(liang)段(duan)長(chang)半徑圓弧、兩(liang)(liang)(liang)段(duan)短半徑圓弧和(he)(he)(he)四(si)段(duan)過渡曲(qu)線(xian)八(ba)個(ge)部分(fen)組成，且定(ding)子(zi)(zi)(zi)和(he)(he)(he)轉子(zi)(zi)(zi)是(shi)同心的。在圖示轉子(zi)(zi)(zi)順時針方向旋(xuan)轉的情況下(xia)，密封(feng)工(gong)作(zuo)(zuo)腔(qiang)的容積在左(zuo)上角和(he)(he)(he)右下(xia)角處逐漸增大，為(wei)吸油(you)(you)區(qu)，在左(zuo)下(xia)角和(he)(he)(he)右上角處逐漸減(jian)小，為(wei)壓油(you)(you)區(qu)；吸油(you)(you)區(qu)和(he)(he)(he)壓油(you)(you)區(qu)之(zhi)間(jian)有(you)一(yi)段(duan)封(feng)油(you)(you)區(qu)把(ba)它們隔(ge)開。這種泵(beng)(beng)的轉子(zi)(zi)(zi)每轉一(yi)轉，每個(ge)密封(feng)工(gong)作(zuo)(zuo)腔(qiang)完成吸油(you)(you)和(he)(he)(he)壓油(you)(you)動作(zuo)(zuo)各(ge)兩(liang)(liang)(liang)次，所以稱(cheng)(cheng)為(wei)雙作(zuo)(zuo)用(yong)(yong)葉片(pian)(pian)泵(beng)(beng)。泵(beng)(beng)的兩(liang)(liang)(liang)個(ge)吸油(you)(you)區(qu)和(he)(he)(he)兩(liang)(liang)(liang)個(ge)壓油(you)(you)區(qu)是(shi)徑向對稱(cheng)(cheng)的，作(zuo)(zuo)用(yong)(yong)在轉子(zi)(zi)(zi)上的液壓力徑向平衡(heng)，所以又稱(cheng)(cheng)為(wei)平衡(heng)式葉片(pian)(pian)泵(beng)(beng)。 雙作用葉片(pian)泵(beng)的(de)瞬(shun)時流量是脈動(dong)的(de)，當葉片(pian)數(shu)為4的(de)倍數(shu)時脈動(dong)率小。為此，雙作用葉片(pian)泵(beng)的(de)葉片(pian)數(shu)一(yi)般都(dou)取12或16。 意大利進口ATOS葉片泵部分(fen)型號(hao)： PFE-31028/1DV
