一、單作用葉片泵的工作原理: ATOS葉(xie)(xie)(xie)(xie)片(pian)(pian)泵(beng)由轉(zhuan)(zhuan)(zhuan)子(zi)1、定(ding)子(zi)2、葉(xie)(xie)(xie)(xie)片(pian)(pian)3、配(pei)(pei)油(you)盤和端蓋等部件所組成。定(ding)子(zi)的(de)(de)內(nei)(nei)表(biao)面(mian)是圓柱形(xing)孔。轉(zhuan)(zhuan)(zhuan)子(zi)和定(ding)子(zi)之間(jian)(jian)存在(zai)著偏(pian)心。葉(xie)(xie)(xie)(xie)片(pian)(pian)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)的(de)(de)槽(cao)內(nei)(nei)可(ke)靈活滑動,在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)動時的(de)(de)離心力以及通入葉(xie)(xie)(xie)(xie)片(pian)(pian)根部壓(ya)力油(you)的(de)(de)作(zuo)用(yong)下,葉(xie)(xie)(xie)(xie)片(pian)(pian)頂部貼緊在(zai)定(ding)子(zi)內(nei)(nei)表(biao)面(mian)上(shang),于是兩相鄰葉(xie)(xie)(xie)(xie)片(pian)(pian)、配(pei)(pei)油(you)盤、定(ding)子(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)(jian)便形(xing)成了(le)一(yi)個個密(mi)封的(de)(de)工作(zuo)腔(qiang)。當轉(zhuan)(zhuan)(zhuan)子(zi)按逆時針(zhen)方向(xiang)旋轉(zhuan)(zhuan)(zhuan)時,圖右側的(de)(de)葉(xie)(xie)(xie)(xie)片(pian)(pian)向(xiang)外伸(shen)出(chu),密(mi)封工作(zuo)腔(qiang)容積(ji)(ji)逐(zhu)漸增大,產生真空,于是通過吸油(you)口6和配(pei)(pei)油(you)盤5上(shang)窗口將油(you)吸入。而在(zai)圖的(de)(de)左側。葉(xie)(xie)(xie)(xie)片(pian)(pian)往里縮進,密(mi)封腔(qiang)的(de)(de)容積(ji)(ji)逐(zhu)漸縮小,密(mi)封腔(qiang)中(zhong)的(de)(de)油(you)液(ye)經配(pei)(pei)油(you)盤另一(yi)窗口和壓(ya)油(you)口1被壓(ya)出(chu)而輸出(chu)到系統(tong)中(zhong)去。這種泵(beng)在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)一(yi)轉(zhuan)(zhuan)(zhuan)過程中(zhong),吸油(you)壓(ya)油(you)各一(yi)次,故(gu)(gu)稱單作(zuo)用(yong)泵(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)受到徑(jing)向(xiang)液(ye)壓(ya)不平衡作(zuo)用(yong)力,故(gu)(gu)又稱非平衡式泵(beng),其軸承負載較大。改變(bian)定(ding)子(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)間(jian)(jian)的(de)(de)偏(pian)心量,便可(ke)改變(bian)泵(beng)的(de)(de)排量,故(gu)(gu)這種泵(beng)都是變(bian)量泵(beng)。 二(er)、雙作用葉(xie)片泵的工作原(yuan)理(li): ATOS葉(xie)片泵的(de)作(zuo)用原理和(he)單(dan)作(zuo)用葉(xie)片泵相(xiang)似,不同之處(chu)只在(zai)于定子表面是(shi)由兩段(duan)長半(ban)徑(jing)圓弧、兩段(duan)短(duan)半(ban)徑(jing)圓弧和(he)四段(duan)過渡曲線八(ba)個(ge)部分組成,且定子和(he)轉子是(shi)同心的(de)。在(zai)圖示(shi)轉子順時針(zhen)方向旋轉的(de)情況下,密封工(gong)作(zuo)腔的(de)容積在(zai)左上(shang)角(jiao)和(he)右下角(jiao)處(chu)逐(zhu)漸增(zeng)大,為吸(xi)油(you)(you)區(qu)(qu),在(zai)左下角(jiao)和(he)右上(shang)角(jiao)處(chu)逐(zhu)漸減小,為壓(ya)油(you)(you)區(qu)(qu);吸(xi)油(you)(you)區(qu)(qu)和(he)壓(ya)油(you)(you)區(qu)(qu)之間有一段(duan)封油(you)(you)區(qu)(qu)把(ba)它們隔(ge)開。這種泵的(de)轉子每轉一轉,每個(ge)密封工(gong)作(zuo)腔完成吸(xi)油(you)(you)和(he)壓(ya)油(you)(you)動作(zuo)各兩次,所以(yi)稱為雙(shuang)作(zuo)用葉(xie)片泵。泵的(de)兩個(ge)吸(xi)油(you)(you)區(qu)(qu)和(he)兩個(ge)壓(ya)油(you)(you)區(qu)(qu)是(shi)徑(jing)向對稱的(de),作(zuo)用在(zai)轉子上(shang)的(de)液壓(ya)力徑(jing)向平(ping)衡,所以(yi)又稱為平(ping)衡式(shi)葉(xie)片泵。 雙作用葉片(pian)(pian)泵的(de)(de)瞬時流量(liang)是脈(mo)動(dong)(dong)的(de)(de),當葉片(pian)(pian)數(shu)為4的(de)(de)倍(bei)數(shu)時脈(mo)動(dong)(dong)率小(xiao)。為此,雙作用葉片(pian)(pian)泵的(de)(de)葉片(pian)(pian)數(shu)一般都(dou)取12或16。 意大利進口ATOS葉片泵部(bu)分型號(hao): 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 |
