一、單作用葉片泵的工作原(yuan)理(li)： ATOS葉(xie)(xie)(xie)片(pian)(pian)(pian)泵(beng)(beng)(beng)(beng)(beng)由轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)1、定子(zi)(zi)(zi)2、葉(xie)(xie)(xie)片(pian)(pian)(pian)3、配(pei)油(you)(you)(you)盤(pan)和(he)端蓋等部件所組成。定子(zi)(zi)(zi)的(de)(de)(de)(de)內(nei)表(biao)面(mian)是(shi)(shi)圓柱形孔。轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)和(he)定子(zi)(zi)(zi)之間(jian)存在著(zhu)偏(pian)心。葉(xie)(xie)(xie)片(pian)(pian)(pian)在轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)(de)(de)槽(cao)內(nei)可靈活滑動(dong)，在轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)動(dong)時的(de)(de)(de)(de)離心力以(yi)及通入葉(xie)(xie)(xie)片(pian)(pian)(pian)根部壓力油(you)(you)(you)的(de)(de)(de)(de)作用(yong)下(xia)，葉(xie)(xie)(xie)片(pian)(pian)(pian)頂(ding)部貼緊在定子(zi)(zi)(zi)內(nei)表(biao)面(mian)上，于是(shi)(shi)兩相鄰(lin)葉(xie)(xie)(xie)片(pian)(pian)(pian)、配(pei)油(you)(you)(you)盤(pan)、定子(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)間(jian)便形成了一(yi)(yi)個個密(mi)(mi)(mi)封的(de)(de)(de)(de)工作腔(qiang)(qiang)(qiang)(qiang)。當轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)按逆時針方向旋轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)時，圖右側的(de)(de)(de)(de)葉(xie)(xie)(xie)片(pian)(pian)(pian)向外伸出(chu)，密(mi)(mi)(mi)封工作腔(qiang)(qiang)(qiang)(qiang)容(rong)積逐漸增大，產生真空，于是(shi)(shi)通過吸(xi)油(you)(you)(you)口(kou)6和(he)配(pei)油(you)(you)(you)盤(pan)5上窗(chuang)(chuang)口(kou)將油(you)(you)(you)吸(xi)入。而(er)在圖的(de)(de)(de)(de)左側。葉(xie)(xie)(xie)片(pian)(pian)(pian)往里縮進，密(mi)(mi)(mi)封腔(qiang)(qiang)(qiang)(qiang)的(de)(de)(de)(de)容(rong)積逐漸縮小，密(mi)(mi)(mi)封腔(qiang)(qiang)(qiang)(qiang)中(zhong)的(de)(de)(de)(de)油(you)(you)(you)液經(jing)配(pei)油(you)(you)(you)盤(pan)另一(yi)(yi)窗(chuang)(chuang)口(kou)和(he)壓油(you)(you)(you)口(kou)1被壓出(chu)而(er)輸出(chu)到(dao)系統中(zhong)去。這種泵(beng)(beng)(beng)(beng)(beng)在轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)一(yi)(yi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)過程(cheng)中(zhong)，吸(xi)油(you)(you)(you)壓油(you)(you)(you)各一(yi)(yi)次，故(gu)(gu)稱(cheng)單作用(yong)泵(beng)(beng)(beng)(beng)(beng)。轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)受到(dao)徑(jing)向液壓不平衡作用(yong)力，故(gu)(gu)又稱(cheng)非平衡式泵(beng)(beng)(beng)(beng)(beng)，其軸承(cheng)負(fu)載較(jiao)大。改變定子(zi)(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)間(jian)的(de)(de)(de)(de)偏(pian)心量，便可改變泵(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)排量，故(gu)(gu)這種泵(beng)(beng)(beng)(beng)(beng)都是(shi)(shi)變量泵(beng)(beng)(beng)(beng)(beng)。 二(er)、雙(shuang)作用葉片泵(beng)的工作原理： ATOS葉片(pian)泵(beng)(beng)的(de)(de)作(zuo)用原理和(he)(he)單作(zuo)用葉片(pian)泵(beng)(beng)相似，不(bu)同(tong)之處(chu)(chu)只在(zai)(zai)于(yu)定子(zi)(zi)表面是由(you)兩段(duan)長半徑圓(yuan)弧、兩段(duan)短半徑圓(yuan)弧和(he)(he)四段(duan)過渡曲線八(ba)個(ge)(ge)部分組成，且定子(zi)(zi)和(he)(he)轉(zhuan)子(zi)(zi)是同(tong)心的(de)(de)。在(zai)(zai)圖(tu)示轉(zhuan)子(zi)(zi)順時針方(fang)向旋轉(zhuan)的(de)(de)情況(kuang)下(xia)，密封(feng)工作(zuo)腔的(de)(de)容積在(zai)(zai)左上(shang)角和(he)(he)右(you)下(xia)角處(chu)(chu)逐(zhu)漸增(zeng)大(da)，為(wei)吸油(you)(you)(you)區(qu)(qu)(qu)，在(zai)(zai)左下(xia)角和(he)(he)右(you)上(shang)角處(chu)(chu)逐(zhu)漸減小，為(wei)壓(ya)油(you)(you)(you)區(qu)(qu)(qu)；吸油(you)(you)(you)區(qu)(qu)(qu)和(he)(he)壓(ya)油(you)(you)(you)區(qu)(qu)(qu)之間有一(yi)段(duan)封(feng)油(you)(you)(you)區(qu)(qu)(qu)把它們隔(ge)開。這種泵(beng)(beng)的(de)(de)轉(zhuan)子(zi)(zi)每轉(zhuan)一(yi)轉(zhuan)，每個(ge)(ge)密封(feng)工作(zuo)腔完(wan)成吸油(you)(you)(you)和(he)(he)壓(ya)油(you)(you)(you)動作(zuo)各兩次，所以稱為(wei)雙作(zuo)用葉片(pian)泵(beng)(beng)。泵(beng)(beng)的(de)(de)兩個(ge)(ge)吸油(you)(you)(you)區(qu)(qu)(qu)和(he)(he)兩個(ge)(ge)壓(ya)油(you)(you)(you)區(qu)(qu)(qu)是徑向對稱的(de)(de)，作(zuo)用在(zai)(zai)轉(zhuan)子(zi)(zi)上(shang)的(de)(de)液壓(ya)力徑向平衡，所以又稱為(wei)平衡式(shi)葉片(pian)泵(beng)(beng)。 雙作用葉(xie)片泵(beng)的(de)瞬時流量(liang)是脈動的(de)，當葉(xie)片數為4的(de)倍數時脈動率小(xiao)。為此(ci)，雙作用葉(xie)片泵(beng)的(de)葉(xie)片數一般都取12或16。 意大利進口ATOS葉片泵部分(fen)型(xing)號： PFE-31028/1DV
