意大利進口阿托斯葉片泵PFE-41045/1DT 一、單作用葉片泵的工作原理: ATOS葉片(pian)泵(beng)(beng)由轉(zhuan)(zhuan)(zhuan)子(zi)1、定(ding)子(zi)2、葉片(pian)3、配油(you)(you)(you)(you)(you)(you)盤和端蓋等部(bu)件所組成。定(ding)子(zi)的(de)(de)(de)(de)內表面(mian)是圓柱(zhu)形(xing)孔。轉(zhuan)(zhuan)(zhuan)子(zi)和定(ding)子(zi)之間(jian)存在著偏心(xin)。葉片(pian)在轉(zhuan)(zhuan)(zhuan)子(zi)的(de)(de)(de)(de)槽(cao)內可靈(ling)活滑(hua)動,在轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)動時的(de)(de)(de)(de)離心(xin)力(li)以及(ji)通(tong)(tong)入葉片(pian)根部(bu)壓力(li)油(you)(you)(you)(you)(you)(you)的(de)(de)(de)(de)作用(yong)下,葉片(pian)頂部(bu)貼緊在定(ding)子(zi)內表面(mian)上,于(yu)是兩相鄰(lin)葉片(pian)、配油(you)(you)(you)(you)(you)(you)盤、定(ding)子(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)便形(xing)成了一個個密封(feng)(feng)的(de)(de)(de)(de)工(gong)作腔(qiang)。當轉(zhuan)(zhuan)(zhuan)子(zi)按逆時針(zhen)方向(xiang)旋(xuan)轉(zhuan)(zhuan)(zhuan)時,圖右側的(de)(de)(de)(de)葉片(pian)向(xiang)外伸出(chu),密封(feng)(feng)工(gong)作腔(qiang)容積逐漸增大,產生(sheng)真空,于(yu)是通(tong)(tong)過吸(xi)油(you)(you)(you)(you)(you)(you)口6和配油(you)(you)(you)(you)(you)(you)盤5上窗口將油(you)(you)(you)(you)(you)(you)吸(xi)入。而在圖的(de)(de)(de)(de)左(zuo)側。葉片(pian)往里縮進,密封(feng)(feng)腔(qiang)的(de)(de)(de)(de)容積逐漸縮小,密封(feng)(feng)腔(qiang)中的(de)(de)(de)(de)油(you)(you)(you)(you)(you)(you)液(ye)經配油(you)(you)(you)(you)(you)(you)盤另(ling)一窗口和壓油(you)(you)(you)(you)(you)(you)口1被(bei)壓出(chu)而輸出(chu)到系(xi)統中去。這種泵(beng)(beng)在轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)過程中,吸(xi)油(you)(you)(you)(you)(you)(you)壓油(you)(you)(you)(you)(you)(you)各(ge)一次(ci),故(gu)稱單作用(yong)泵(beng)(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)受到徑向(xiang)液(ye)壓不平衡作用(yong)力(li),故(gu)又稱非(fei)平衡式泵(beng)(beng),其(qi)軸承(cheng)負載較大。改變定(ding)子(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)的(de)(de)(de)(de)偏心(xin)量(liang),便可改變泵(beng)(beng)的(de)(de)(de)(de)排量(liang),故(gu)這種泵(beng)(beng)都(dou)是變量(liang)泵(beng)(beng)。 二、雙作用(yong)葉(xie)片泵的(de)工(gong)作原理: ATOS葉(xie)片(pian)泵(beng)的(de)作(zuo)(zuo)用(yong)(yong)原理(li)和(he)(he)(he)單作(zuo)(zuo)用(yong)(yong)葉(xie)片(pian)泵(beng)相似,不同之(zhi)處只在于定(ding)子表(biao)面是由兩(liang)段(duan)長半徑(jing)圓弧、兩(liang)段(duan)短半徑(jing)圓弧和(he)(he)(he)四段(duan)過渡(du)曲線八(ba)個部分(fen)組成,且(qie)定(ding)子和(he)(he)(he)轉(zhuan)(zhuan)(zhuan)(zhuan)子是同心的(de)。在圖示轉(zhuan)(zhuan)(zhuan)(zhuan)子順時針方向(xiang)旋(xuan)轉(zhuan)(zhuan)(zhuan)(zhuan)的(de)情況下(xia),密(mi)封(feng)(feng)工(gong)(gong)作(zuo)(zuo)腔的(de)容積在左上(shang)角和(he)(he)(he)右下(xia)角處逐漸增大,為(wei)吸油(you)區(qu)(qu),在左下(xia)角和(he)(he)(he)右上(shang)角處逐漸減小,為(wei)壓油(you)區(qu)(qu);吸油(you)區(qu)(qu)和(he)(he)(he)壓油(you)區(qu)(qu)之(zhi)間有(you)一段(duan)封(feng)(feng)油(you)區(qu)(qu)把它們隔開。這種泵(beng)的(de)轉(zhuan)(zhuan)(zhuan)(zhuan)子每轉(zhuan)(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)(zhuan),每個密(mi)封(feng)(feng)工(gong)(gong)作(zuo)(zuo)腔完成吸油(you)和(he)(he)(he)壓油(you)動作(zuo)(zuo)各兩(liang)次(ci),所(suo)以稱(cheng)為(wei)雙作(zuo)(zuo)用(yong)(yong)葉(xie)片(pian)泵(beng)。泵(beng)的(de)兩(liang)個吸油(you)區(qu)(qu)和(he)(he)(he)兩(liang)個壓油(you)區(qu)(qu)是徑(jing)向(xiang)對稱(cheng)的(de),作(zuo)(zuo)用(yong)(yong)在轉(zhuan)(zhuan)(zhuan)(zhuan)子上(shang)的(de)液(ye)壓力(li)徑(jing)向(xiang)平(ping)衡(heng),所(suo)以又稱(cheng)為(wei)平(ping)衡(heng)式(shi)葉(xie)片(pian)泵(beng)。 雙(shuang)作用葉(xie)片泵(beng)的(de)瞬(shun)時(shi)流量是脈動(dong)的(de),當葉(xie)片數(shu)為4的(de)倍數(shu)時(shi)脈動(dong)率小。為此,雙(shuang)作用葉(xie)片泵(beng)的(de)葉(xie)片數(shu)一(yi)般都取(qu)12或16。 ATOS葉片泵部分型號: PFE-31028/1DV PFE-31036/1DT PFE-31036/1DU 20 PFE-31036/1DV 20 PFE-31036/1DW PFE-31044/1DT 20 PFE-31044/1DU 20 PFE-31044/1DV 20 PFE-32028/3DT 20 PFE-32028/3DV 20 PFE-32036/3DT PFE-41037/1DU 20 PFE-41045/1DT PFE-41045/1DU 20 PFE-41045/1DW 20 PFE-41056/1DT PFE-41056/1DU 20 PFE-41056/1DV 20 PFE-41056/1DW 20 PFE-41070/1DT PFE-41070/1DV 20 PFE-41070/2DT 20 PFE-41070/2DV 20 PFE-41085/1DT 20 PFE-41085/1DW 20 PFE-42045/3DW 20 PFE-42056/3DU 20 PFE-42070/3DT 20 PFE-42070/3DU PFE-42070/3DW 20 PFE-42070/7DV PFE-51090/1DT 23 PFE-51090/1DU PFE-51110/1DT 23 PFE-51110/1DU 23 PFE-51110/3DT 23 PFE-51129/1DT PFE-51150/1DT PFE-51150/3DV PFE-52090/3DT 31 PFE-52110/3DT 31 意大利進口ATOS葉片泵PFE-41045/1DT |
