伊頓威(wei)格士VICKERS葉片泵結(jie)構(gou)特點

    1.配油(you)(you)盤：雙作(zuo)用葉片泵配油(you)(you)盤，如(ru)下圖所示(shi)

    在盤(pan)上(shang)有(you)兩個(ge)吸(xi)油(you)(you)(you)(you)(you)窗口(kou)(kou)2、4和兩個(ge)壓(ya)油(you)(you)(you)(you)(you)窗口(kou)(kou)1、3，窗口(kou)(kou)之(zhi)間(jian)為(wei)封(feng)油(you)(you)(you)(you)(you)區(qu)，通(tong)(tong)常應(ying)使(shi)封(feng)油(you)(you)(you)(you)(you)區(qu)對應(ying)的(de)(de)中(zhong)心角(jiao)a稍大于或等于兩個(ge)葉(xie)片(pian)(pian)之(zhi)間(jian)的(de)(de)夾角(jiao)B，否(fou)則會(hui)使(shi)吸(xi)油(you)(you)(you)(you)(you)腔(qiang)(qiang)和壓(ya)油(you)(you)(you)(you)(you)腔(qiang)(qiang)連通(tong)(tong)，造成泄漏(lou)。當兩個(ge)葉(xie)片(pian)(pian)間(jian)的(de)(de)密(mi)封(feng)油(you)(you)(you)(you)(you)液(ye)從吸(xi)油(you)(you)(you)(you)(you)區(qu)過(guo)(guo)渡到封(feng)油(you)(you)(you)(you)(you)區(qu)（大圓弧(hu)處(chu)）時，其壓(ya)力(li)(li)基本上(shang)與吸(xi)油(you)(you)(you)(you)(you)壓(ya)力(li)(li)相(xiang)同，但當轉(zhuan)子(zi)再(zai)繼續旋轉(zhuan)一(yi)(yi)個(ge)微小角(jiao)度時，該(gai)密(mi)封(feng)腔(qiang)(qiang)突(tu)(tu)(tu)然(ran)與壓(ya)油(you)(you)(you)(you)(you)腔(qiang)(qiang)相(xiang)通(tong)(tong)，使(shi)其中(zhong)油(you)(you)(you)(you)(you)液(ye)壓(ya)力(li)(li)突(tu)(tu)(tu)然(ran)升高，油(you)(you)(you)(you)(you)液(ye)的(de)(de)體積突(tu)(tu)(tu)然(ran)收縮，壓(ya)油(you)(you)(you)(you)(you)腔(qiang)(qiang)中(zhong)的(de)(de)油(you)(you)(you)(you)(you)液(ye)倒流進該(gai)腔(qiang)(qiang)，使(shi)液(ye)壓(ya)泵的(de)(de)瞬時流量(liang)突(tu)(tu)(tu)然(ran)減小，引(yin)起(qi)液(ye)壓(ya)泵的(de)(de)流量(liang)脈(mo)動(dong)(dong)、壓(ya)力(li)(li)脈(mo)動(dong)(dong)和噪(zao)聲(sheng)。因此(ci)在配油(you)(you)(you)(you)(you)盤(pan)的(de)(de)壓(ya)油(you)(you)(you)(you)(you)窗口(kou)(kou)靠葉(xie)片(pian)(pian)從封(feng)油(you)(you)(you)(you)(you)區(qu)進入壓(ya)油(you)(you)(you)(you)(you)區(qu)的(de)(de)一(yi)(yi)邊開(kai)有(you)一(yi)(yi)個(ge)截(jie)面形狀為(wei)三(san)角(jiao)形的(de)(de)三(san)角(jiao)槽（又稱眉毛槽），使(shi)兩葉(xie)片(pian)(pian)之(zhi)間(jian)的(de)(de)封(feng)閉油(you)(you)(you)(you)(you)液(ye)在末進入壓(ya)油(you)(you)(you)(you)(you)區(qu)之(zhi)前就通(tong)(tong)過(guo)(guo)該(gai)三(san)角(jiao)槽與壓(ya)力(li)(li)油(you)(you)(you)(you)(you)相(xiang)通(tong)(tong)，使(shi)其壓(ya)力(li)(li)逐(zhu)漸上(shang)升，因而緩解了流量(liang)和壓(ya)力(li)(li)脈(mo)動(dong)(dong)并降低了噪(zao)音。槽c與壓(ya)油(you)(you)(you)(you)(you)腔(qiang)(qiang)相(xiang)通(tong)(tong)并轉(zhuan)子(zi)葉(xie)片(pian)(pian)槽底部相(xiang)通(tong)(tong)，使(shi)葉(xie)片(pian)(pian)的(de)(de)底部作用有(you)壓(ya)力(li)(li)油(you)(you)(you)(you)(you)。

    3-壓油窗(chuang)口(kou)；4-吸油窗(chuang)口(kou)

    3.定子曲線(xian)：由四段圓弧和四段過渡曲線(xian)組成。

    過(guo)渡(du)曲(qu)(qu)線(xian)應保證葉片(pian)貼緊(jin)在定(ding)子內(nei)表(biao)面(mian)上，保證葉片(pian)在轉子槽中(zhong)徑(jing)向運動時速(su)(su)度(du)和(he)加速(su)(su)度(du)變化均勻，使葉片(pian)對定(ding)子的(de)(de)內(nei)表(biao)面(mian)的(de)(de)沖擊盡可能小。定(ding)子過(guo)渡(du)曲(qu)(qu)線(xian)主(zhu)要有以下(xia)幾種(zhong)：修正的(de)(de)阿基米德螺線(xian)；正弦加速(su)(su)曲(qu)(qu)線(xian)；等(deng)加速(su)(su)一等(deng)減速(su)(su)曲(qu)(qu)線(xian)；高次曲(qu)(qu)線(xian)。在最為新(xin)型的(de)(de)泵中(zhong)多采用等(deng)加速(su)(su)一等(deng)減速(su)(su)曲(qu)(qu)線(xian)。

    4.葉(xie)(xie)(xie)片(pian)(pian)的(de)傾角：葉(xie)(xie)(xie)片(pian)(pian)在工作(zuo)過程中(zhong)，受(shou)離心(xin)(xin)力(li)和葉(xie)(xie)(xie)片(pian)(pian)根部壓力(li)油的(de)作(zuo)用(yong)，使葉(xie)(xie)(xie)片(pian)(pian)和定子(zi)(zi)緊密接觸(chu)。當葉(xie)(xie)(xie)片(pian)(pian)轉(zhuan)至壓油區時，定子(zi)(zi)內壁(bi)迫使葉(xie)(xie)(xie)片(pian)(pian)縮(suo)向(xiang)轉(zhuan)子(zi)(zi)中(zhong)心(xin)(xin)研究(jiu)表(biao)明，在雙作(zuo)用(yong)葉(xie)(xie)(xie)片(pian)(pian)泵(beng)中(zhong)，將葉(xie)(xie)(xie)片(pian)(pian)順(shun)著轉(zhuan)子(zi)(zi)回(hui)轉(zhuan)方向(xiang)前傾一個角度（向(xiang)前傾斜13°），可(ke)減小(xiao)定子(zi)(zi)內壁(bi)對葉(xie)(xie)(xie)片(pian)(pian)作(zuo)用(yong)的(de)側向(xiang)力(li)，使葉(xie)(xie)(xie)片(pian)(pian)在槽中(zhong)移動靈活(huo)，并可(ke)減少(shao)磨損。但近(jin)年的(de)研究(jiu)表(biao)明，某些(xie)高(gao)壓雙作(zuo)用(yong)葉(xie)(xie)(xie)片(pian)(pian)泵(beng)的(de)轉(zhuan)子(zi)(zi)槽是徑向(xiang)的(de)，且使用(yong)情況良好。

1.泵(beng)轉(zhuan)向(xiang)改(gai)變，則(ze)其吸(xi)排方向(xiang)也改(gai)變葉(xie)片(pian)泵(beng)都(dou)有規定(ding)的(de)轉(zhuan)向(xiang)，不允許反。因為轉(zhuan)子葉(xie)槽(cao)有傾斜，葉(xie)片(pian)有倒角，葉(xie)片(pian)底部與排油腔(qiang)通(tong)，配油盤上的(de)節流槽(cao)和吸(xi)、排口(kou)是按(an)既(ji)定(ding)轉(zhuan)向(xiang)設計。可逆轉(zhuan)的(de)葉(xie)片(pian)泵(beng)必須專門設計。

2.葉片泵裝(zhuang)配(pei) 配(pei)油(you)(you)盤(pan)與定子(zi)用(yong)定位(wei)銷正確定位(wei)，葉片、轉子(zi)、配(pei)油(you)(you)盤(pan)都不(bu)得裝(zhuang)反，定子(zi)內表(biao)面吸入區部分最易磨損，必要時(shi)可將其翻(fan)轉安裝(zhuang)，以使原吸入區變(bian)為排出(chu)區而繼續使用(yong)。

3.拆裝 注意工(gong)作(zuo)表(biao)面清潔，工(gong)作(zuo)時(shi)油液(ye)應很(hen)好過濾。

4. 葉(xie)片在葉(xie)槽中的間隙太大會使漏(lou)泄增加，太小(xiao)則葉(xie)片不能自由伸縮，會導致(zhi)工作失常。

5.葉片泵的軸(zhou)向間隙 對ηv影響(xiang)很大。

1)小(xiao)型泵-0.015~0.03mm

2)中型(xing)泵-0.02~0.045mm

6.油(you)液的(de)溫(wen)度(du)和粘度(du)?一般不宜超過55℃，粘度(du)要求在17~37mm2/s之(zhi)間。粘度(du)太大則吸油(you)困難;粘度(du)太小則漏泄(xie)嚴重。

作為泵產品，葉片泵更多地指滑片泵。只要你有興趣在度搜索發現，葉片泵幾乎全部指滑片泵。伊頓威格士VICKERS葉片泵原廠直供實物圖片：
