一、單作用葉片泵(beng)的工作原理： ATOS葉(xie)(xie)(xie)片(pian)(pian)泵(beng)由轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)1、定(ding)(ding)(ding)(ding)子(zi)(zi)(zi)(zi)2、葉(xie)(xie)(xie)片(pian)(pian)3、配油(you)(you)盤(pan)(pan)和端蓋等部件所組(zu)成。定(ding)(ding)(ding)(ding)子(zi)(zi)(zi)(zi)的(de)內(nei)(nei)表面是(shi)圓柱(zhu)形(xing)孔。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)和定(ding)(ding)(ding)(ding)子(zi)(zi)(zi)(zi)之間存在(zai)(zai)著偏心(xin)。葉(xie)(xie)(xie)片(pian)(pian)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)的(de)槽(cao)內(nei)(nei)可(ke)靈活滑動(dong)，在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)動(dong)時(shi)的(de)離心(xin)力(li)(li)以(yi)及通入葉(xie)(xie)(xie)片(pian)(pian)根部壓(ya)力(li)(li)油(you)(you)的(de)作用(yong)下，葉(xie)(xie)(xie)片(pian)(pian)頂部貼緊在(zai)(zai)定(ding)(ding)(ding)(ding)子(zi)(zi)(zi)(zi)內(nei)(nei)表面上，于是(shi)兩相鄰葉(xie)(xie)(xie)片(pian)(pian)、配油(you)(you)盤(pan)(pan)、定(ding)(ding)(ding)(ding)子(zi)(zi)(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)間便形(xing)成了一(yi)個個密封(feng)(feng)的(de)工(gong)作腔(qiang)。當轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)按逆時(shi)針方向旋轉(zhuan)(zhuan)(zhuan)(zhuan)時(shi)，圖右側的(de)葉(xie)(xie)(xie)片(pian)(pian)向外(wai)伸出(chu)，密封(feng)(feng)工(gong)作腔(qiang)容積(ji)逐漸增大(da)，產(chan)生真(zhen)空，于是(shi)通過(guo)(guo)吸(xi)油(you)(you)口(kou)6和配油(you)(you)盤(pan)(pan)5上窗(chuang)口(kou)將油(you)(you)吸(xi)入。而(er)(er)在(zai)(zai)圖的(de)左側。葉(xie)(xie)(xie)片(pian)(pian)往里縮(suo)(suo)進(jin)，密封(feng)(feng)腔(qiang)的(de)容積(ji)逐漸縮(suo)(suo)小(xiao)，密封(feng)(feng)腔(qiang)中(zhong)(zhong)的(de)油(you)(you)液經配油(you)(you)盤(pan)(pan)另(ling)一(yi)窗(chuang)口(kou)和壓(ya)油(you)(you)口(kou)1被壓(ya)出(chu)而(er)(er)輸出(chu)到(dao)系統中(zhong)(zhong)去(qu)。這(zhe)種泵(beng)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)一(yi)轉(zhuan)(zhuan)(zhuan)(zhuan)過(guo)(guo)程(cheng)中(zhong)(zhong)，吸(xi)油(you)(you)壓(ya)油(you)(you)各一(yi)次，故(gu)稱單作用(yong)泵(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)受到(dao)徑向液壓(ya)不平衡作用(yong)力(li)(li)，故(gu)又(you)稱非平衡式泵(beng)，其(qi)軸承負載較(jiao)大(da)。改變定(ding)(ding)(ding)(ding)子(zi)(zi)(zi)(zi)和轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)(zi)間的(de)偏心(xin)量，便可(ke)改變泵(beng)的(de)排量，故(gu)這(zhe)種泵(beng)都是(shi)變量泵(beng)。 二、雙作用葉(xie)片泵的工作原理： ATOS葉(xie)(xie)片(pian)泵(beng)(beng)的(de)作(zuo)(zuo)用(yong)(yong)原理和(he)單作(zuo)(zuo)用(yong)(yong)葉(xie)(xie)片(pian)泵(beng)(beng)相(xiang)似，不同之(zhi)處(chu)(chu)只在(zai)于定(ding)子表面是由兩段(duan)長(chang)半徑圓弧、兩段(duan)短(duan)半徑圓弧和(he)四段(duan)過渡曲線八個(ge)部分組成(cheng)，且定(ding)子和(he)轉子是同心的(de)。在(zai)圖示轉子順時(shi)針方向旋轉的(de)情況下(xia)，密封工(gong)作(zuo)(zuo)腔的(de)容積在(zai)左(zuo)上角(jiao)和(he)右(you)下(xia)角(jiao)處(chu)(chu)逐(zhu)漸(jian)增大，為(wei)(wei)(wei)吸油區，在(zai)左(zuo)下(xia)角(jiao)和(he)右(you)上角(jiao)處(chu)(chu)逐(zhu)漸(jian)減小，為(wei)(wei)(wei)壓(ya)油區；吸油區和(he)壓(ya)油區之(zhi)間有一段(duan)封油區把它們隔(ge)開。這種(zhong)泵(beng)(beng)的(de)轉子每轉一轉，每個(ge)密封工(gong)作(zuo)(zuo)腔完成(cheng)吸油和(he)壓(ya)油動作(zuo)(zuo)各兩次，所以稱為(wei)(wei)(wei)雙作(zuo)(zuo)用(yong)(yong)葉(xie)(xie)片(pian)泵(beng)(beng)。泵(beng)(beng)的(de)兩個(ge)吸油區和(he)兩個(ge)壓(ya)油區是徑向對稱的(de)，作(zuo)(zuo)用(yong)(yong)在(zai)轉子上的(de)液壓(ya)力徑向平(ping)(ping)衡(heng)，所以又(you)稱為(wei)(wei)(wei)平(ping)(ping)衡(heng)式葉(xie)(xie)片(pian)泵(beng)(beng)。 雙(shuang)作用(yong)(yong)葉片泵的(de)(de)瞬時流量是脈動的(de)(de)，當(dang)葉片數為4的(de)(de)倍數時脈動率(lv)小(xiao)。為此，雙(shuang)作用(yong)(yong)葉片泵的(de)(de)葉片數一般都取12或16。 意大利進口ATOS葉片泵部分型號： PFE-31028/1DV
