全新原廠阿托斯葉片泵PFE-31028/1DV葉(xie)(xie)片泵轉子旋轉時(shi),葉(xie)(xie)片在(zai)(zai)離心力和壓力油(you)(you)的(de)作(zuo)用下,尖部緊貼在(zai)(zai)定子內(nei)表(biao)面上。這樣兩個葉(xie)(xie)片與轉子和定子內(nei)表(biao)面所構成的(de)工作(zuo)容積,先由小到大(da)吸(xi)油(you)(you)后再(zai)由大(da)到小排(pai)油(you)(you),葉(xie)(xie)片旋轉一(yi)周時(shi),完成一(yi)次(ci)吸(xi)油(you)(you)與排(pai)油(you)(you)。
一、單作用葉片(pian)泵(beng)的工作原理: ATOS葉(xie)片(pian)(pian)泵(beng)由轉(zhuan)(zhuan)(zhuan)子(zi)(zi)1、定(ding)子(zi)(zi)2、葉(xie)片(pian)(pian)3、配(pei)油(you)(you)盤和(he)端蓋等部(bu)件(jian)所組成。定(ding)子(zi)(zi)的(de)(de)內(nei)(nei)表(biao)面(mian)(mian)是圓柱形孔。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)和(he)定(ding)子(zi)(zi)之間存(cun)在(zai)著偏心(xin)。葉(xie)片(pian)(pian)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)的(de)(de)槽(cao)內(nei)(nei)可靈活滑(hua)動(dong),在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)動(dong)時的(de)(de)離心(xin)力以及通(tong)(tong)入葉(xie)片(pian)(pian)根部(bu)壓(ya)力油(you)(you)的(de)(de)作(zuo)用下,葉(xie)片(pian)(pian)頂部(bu)貼緊在(zai)定(ding)子(zi)(zi)內(nei)(nei)表(biao)面(mian)(mian)上(shang),于是兩相(xiang)鄰葉(xie)片(pian)(pian)、配(pei)油(you)(you)盤、定(ding)子(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)間便(bian)形成了(le)一個個密(mi)封(feng)的(de)(de)工(gong)作(zuo)腔。當轉(zhuan)(zhuan)(zhuan)子(zi)(zi)按逆時針方向(xiang)(xiang)旋(xuan)轉(zhuan)(zhuan)(zhuan)時,圖右側(ce)的(de)(de)葉(xie)片(pian)(pian)向(xiang)(xiang)外伸出(chu)(chu)(chu),密(mi)封(feng)工(gong)作(zuo)腔容積(ji)逐漸(jian)增大,產生(sheng)真空(kong),于是通(tong)(tong)過吸(xi)(xi)油(you)(you)口6和(he)配(pei)油(you)(you)盤5上(shang)窗口將油(you)(you)吸(xi)(xi)入。而(er)在(zai)圖的(de)(de)左側(ce)。葉(xie)片(pian)(pian)往里(li)縮進(jin),密(mi)封(feng)腔的(de)(de)容積(ji)逐漸(jian)縮小,密(mi)封(feng)腔中的(de)(de)油(you)(you)液經配(pei)油(you)(you)盤另一窗口和(he)壓(ya)油(you)(you)口1被壓(ya)出(chu)(chu)(chu)而(er)輸出(chu)(chu)(chu)到系統中去(qu)。這種泵(beng)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)過程(cheng)中,吸(xi)(xi)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)子(zi)(zi)受到徑向(xiang)(xiang)液壓(ya)不平衡(heng)作(zuo)用力,故(gu)又稱非平衡(heng)式泵(beng),其軸承負載較大。改變(bian)定(ding)子(zi)(zi)和(he)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)間的(de)(de)偏心(xin)量(liang),便(bian)可改變(bian)泵(beng)的(de)(de)排量(liang),故(gu)這種泵(beng)都是變(bian)量(liang)泵(beng)。 二(er)、雙(shuang)作用葉(xie)片(pian)泵的(de)工作原理(li): ATOS葉(xie)片(pian)(pian)泵(beng)的作(zuo)(zuo)用(yong)(yong)原(yuan)理和(he)(he)單作(zuo)(zuo)用(yong)(yong)葉(xie)片(pian)(pian)泵(beng)相似,不同之處(chu)只在于定子(zi)(zi)表(biao)面是由(you)兩(liang)段長半徑(jing)(jing)圓弧(hu)(hu)、兩(liang)段短半徑(jing)(jing)圓弧(hu)(hu)和(he)(he)四段過渡曲線八(ba)個部分組成(cheng),且定子(zi)(zi)和(he)(he)轉(zhuan)(zhuan)子(zi)(zi)是同心的。在圖(tu)示(shi)轉(zhuan)(zhuan)子(zi)(zi)順(shun)時針方向旋轉(zhuan)(zhuan)的情況下,密封(feng)(feng)工作(zuo)(zuo)腔(qiang)的容(rong)積在左(zuo)上角和(he)(he)右下角處(chu)逐漸增大,為吸(xi)(xi)油(you)(you)(you)區(qu)(qu)(qu)(qu),在左(zuo)下角和(he)(he)右上角處(chu)逐漸減小,為壓(ya)油(you)(you)(you)區(qu)(qu)(qu)(qu);吸(xi)(xi)油(you)(you)(you)區(qu)(qu)(qu)(qu)和(he)(he)壓(ya)油(you)(you)(you)區(qu)(qu)(qu)(qu)之間有一段封(feng)(feng)油(you)(you)(you)區(qu)(qu)(qu)(qu)把它們隔開。這種(zhong)泵(beng)的轉(zhuan)(zhuan)子(zi)(zi)每轉(zhuan)(zhuan)一轉(zhuan)(zhuan),每個密封(feng)(feng)工作(zuo)(zuo)腔(qiang)完成(cheng)吸(xi)(xi)油(you)(you)(you)和(he)(he)壓(ya)油(you)(you)(you)動作(zuo)(zuo)各兩(liang)次,所(suo)以稱為雙作(zuo)(zuo)用(yong)(yong)葉(xie)片(pian)(pian)泵(beng)。泵(beng)的兩(liang)個吸(xi)(xi)油(you)(you)(you)區(qu)(qu)(qu)(qu)和(he)(he)兩(liang)個壓(ya)油(you)(you)(you)區(qu)(qu)(qu)(qu)是徑(jing)(jing)向對稱的,作(zuo)(zuo)用(yong)(yong)在轉(zhuan)(zhuan)子(zi)(zi)上的液壓(ya)力徑(jing)(jing)向平衡(heng)(heng),所(suo)以又稱為平衡(heng)(heng)式(shi)葉(xie)片(pian)(pian)泵(beng)。 雙(shuang)作(zuo)(zuo)用(yong)葉(xie)片泵(beng)的瞬時流量是脈動的,當葉(xie)片數(shu)為(wei)4的倍數(shu)時脈動率小。為(wei)此,雙(shuang)作(zuo)(zuo)用(yong)葉(xie)片泵(beng)的葉(xie)片數(shu)一(yi)般都取12或(huo)16。
