ATOS PFE 系列葉片泵注意事項和原理
意大利ATOS葉片泵是阿托斯主要(yao)經營產品之一(yi)，主要(yao)運用(yong)在石油煤(mei)礦等(deng)各種輕重工業，憑(ping)借其優秀(xiu)的(de)品質質量(liang)及高性(xing)價比贏(ying)得了(le)國內外企業的(de)喜歡。是市(shi)場上的(de)主流(liu)品牌之一(yi)。
ATOS PFE 系(xi)列葉片泵原理(li)：
葉(xie)片泵轉子(zi)旋(xuan)轉時，葉(xie)片在(zai)離心力和壓力油(you)的(de)作(zuo)用下，尖(jian)部緊貼在(zai)定子(zi)內(nei)表面上。這樣兩個葉(xie)片與(yu)轉子(zi)和定子(zi)內(nei)表面所構(gou)成的(de)工作(zuo)容(rong)積，先由小到大(da)吸(xi)油(you)后再由大(da)到小排油(you)，葉(xie)片旋(xuan)轉一(yi)周時，完成一(yi)次吸(xi)油(you)與(yu)排油(you)。
一(yi)、單作(zuo)用(yong)葉片(pian)泵的工(gong)作(zuo)原(yuan)理(li)
葉片泵
泵(beng)(beng)(beng)由轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)1、定(ding)子(zi)(zi)(zi)2、葉(xie)(xie)(xie)(xie)片(pian)(pian)3、配(pei)油(you)(you)(you)盤(pan)和端蓋等部件(jian)所組成。定(ding)子(zi)(zi)(zi)的(de)(de)內(nei)(nei)表面是(shi)圓柱形孔。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)和定(ding)子(zi)(zi)(zi)之間(jian)(jian)(jian)存(cun)在(zai)(zai)著(zhu)偏心(xin)。葉(xie)(xie)(xie)(xie)片(pian)(pian)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)槽內(nei)(nei)可靈活滑動(dong)，在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)動(dong)時(shi)(shi)的(de)(de)離心(xin)力以及通(tong)(tong)入(ru)(ru)葉(xie)(xie)(xie)(xie)片(pian)(pian)根部壓力油(you)(you)(you)的(de)(de)作用下，葉(xie)(xie)(xie)(xie)片(pian)(pian)頂部貼緊在(zai)(zai)定(ding)子(zi)(zi)(zi)內(nei)(nei)表面上，于(yu)是(shi)兩(liang)相鄰葉(xie)(xie)(xie)(xie)片(pian)(pian)、配(pei)油(you)(you)(you)盤(pan)、定(ding)子(zi)(zi)(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)間(jian)(jian)(jian)便形成了(le)一(yi)(yi)(yi)個個密封(feng)的(de)(de)工作腔(qiang)。當轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)按(an)逆時(shi)(shi)針方向旋轉(zhuan)(zhuan)(zhuan)時(shi)(shi)，圖(tu)右側(ce)的(de)(de)葉(xie)(xie)(xie)(xie)片(pian)(pian)向外(wai)伸出，密封(feng)工作腔(qiang)容積逐(zhu)漸(jian)增大，產生真(zhen)空，于(yu)是(shi)通(tong)(tong)過吸(xi)(xi)油(you)(you)(you)口6和配(pei)油(you)(you)(you)盤(pan)5上窗口將油(you)(you)(you)吸(xi)(xi)入(ru)(ru)。而在(zai)(zai)圖(tu)的(de)(de)左側(ce)。葉(xie)(xie)(xie)(xie)片(pian)(pian)往里縮進，密封(feng)腔(qiang)的(de)(de)容積逐(zhu)漸(jian)縮小(xiao)，密封(feng)腔(qiang)中(zhong)(zhong)的(de)(de)油(you)(you)(you)液經配(pei)油(you)(you)(you)盤(pan)另一(yi)(yi)(yi)窗口和壓油(you)(you)(you)口1被壓出而輸出到(dao)系統(tong)中(zhong)(zhong)去。這(zhe)種泵(beng)(beng)(beng)在(zai)(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)轉(zhuan)(zhuan)(zhuan)一(yi)(yi)(yi)轉(zhuan)(zhuan)(zhuan)過程中(zhong)(zhong)，吸(xi)(xi)油(you)(you)(you)壓油(you)(you)(you)各一(yi)(yi)(yi)次，故稱(cheng)單作用泵(beng)(beng)(beng)。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)受到(dao)徑(jing)向液壓不平(ping)衡作用力，故又(you)稱(cheng)非平(ping)衡式泵(beng)(beng)(beng)，其軸承負(fu)載較(jiao)大。改(gai)變定(ding)子(zi)(zi)(zi)和轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)間(jian)(jian)(jian)的(de)(de)偏心(xin)量，便可改(gai)變泵(beng)(beng)(beng)的(de)(de)排量，故這(zhe)種泵(beng)(beng)(beng)都是(shi)變量泵(beng)(beng)(beng)。
二、雙(shuang)作用葉片泵的工(gong)作原理
結構
它的作用原理和(he)(he)單作用葉(xie)(xie)片泵(beng)(beng)相似，不(bu)同(tong)之處(chu)只在(zai)于定(ding)子表(biao)面(mian)是(shi)由(you)兩段(duan)(duan)長半(ban)徑圓弧、兩段(duan)(duan)短半(ban)徑圓弧和(he)(he)四段(duan)(duan)過渡(du)曲線八個(ge)部分組成，且定(ding)子和(he)(he)轉(zhuan)(zhuan)(zhuan)子是(shi)同(tong)心的。在(zai)圖示(shi)轉(zhuan)(zhuan)(zhuan)子順時(shi)針方向旋轉(zhuan)(zhuan)(zhuan)的情況下，密(mi)封工作腔(qiang)的容積(ji)在(zai)左(zuo)(zuo)上角(jiao)(jiao)和(he)(he)右下角(jiao)(jiao)處(chu)逐漸增(zeng)大，為吸油(you)(you)(you)區(qu)(qu)(qu)，在(zai)左(zuo)(zuo)下角(jiao)(jiao)和(he)(he)右上角(jiao)(jiao)處(chu)逐漸減小，為壓(ya)(ya)(ya)油(you)(you)(you)區(qu)(qu)(qu)；吸油(you)(you)(you)區(qu)(qu)(qu)和(he)(he)壓(ya)(ya)(ya)油(you)(you)(you)區(qu)(qu)(qu)之間(jian)有一段(duan)(duan)封油(you)(you)(you)區(qu)(qu)(qu)把它們隔開。這(zhe)種泵(beng)(beng)的轉(zhuan)(zhuan)(zhuan)子每(mei)(mei)轉(zhuan)(zhuan)(zhuan)一轉(zhuan)(zhuan)(zhuan)，每(mei)(mei)個(ge)密(mi)封工作腔(qiang)完成吸油(you)(you)(you)和(he)(he)壓(ya)(ya)(ya)油(you)(you)(you)動作各兩次(ci)，所以(yi)稱(cheng)(cheng)為雙作用葉(xie)(xie)片泵(beng)(beng)。泵(beng)(beng)的兩個(ge)吸油(you)(you)(you)區(qu)(qu)(qu)和(he)(he)兩個(ge)壓(ya)(ya)(ya)油(you)(you)(you)區(qu)(qu)(qu)是(shi)徑向對稱(cheng)(cheng)的，作用在(zai)轉(zhuan)(zhuan)(zhuan)子上的液壓(ya)(ya)(ya)力徑向平衡(heng)，所以(yi)又(you)稱(cheng)(cheng)為平衡(heng)式葉(xie)(xie)片泵(beng)(beng)。
雙作用葉(xie)(xie)片(pian)泵(beng)的(de)瞬(shun)時(shi)(shi)流量是脈動的(de)，當葉(xie)(xie)片(pian)數為4的(de)倍數時(shi)(shi)脈動率小(xiao)。為此，雙作用葉(xie)(xie)片(pian)泵(beng)的(de)葉(xie)(xie)片(pian)數一般都取12或16。
ATOS PFE 系(xi)列葉片泵注意事項(xiang)
葉(xie)片泵的管(guan)理要(yao)點除需(xu)防(fang)干轉和過載、防(fang)吸入(ru)(ru)空氣和吸入(ru)(ru)真空度過大外，還(huan)應注意：
1．泵(beng)轉向改變，則其吸(xi)(xi)排(pai)(pai)方向也改變葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)都(dou)有(you)(you)規定(ding)的轉向，不允許反(fan)。因(yin)為轉子葉(xie)(xie)槽有(you)(you)傾斜，葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)有(you)(you)倒角，葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)底部與(yu)排(pai)(pai)油(you)(you)腔通，配油(you)(you)盤上的節流槽和吸(xi)(xi)、排(pai)(pai)口是按既(ji)定(ding)轉向設計。可(ke)逆(ni)轉的葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)必須(xu)專門設計。2．葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)裝(zhuang)(zhuang)配 配油(you)(you)盤與(yu)定(ding)子用定(ding)位銷正確(que)定(ding)位，葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)、轉子、配油(you)(you)盤都(dou)不得(de)裝(zhuang)(zhuang)反(fan)，定(ding)子內(nei)表面吸(xi)(xi)入區部分(fen)最易磨損，必要時可(ke)將(jiang)其翻轉安裝(zhuang)(zhuang)，以使(shi)原吸(xi)(xi)入區變為排(pai)(pai)出區而繼(ji)續使(shi)用。3．拆裝(zhuang)(zhuang) 注意工作(zuo)表面清潔(jie)，工作(zuo)時油(you)(you)液應很(hen)(hen)好(hao)過濾。4. 葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)在葉(xie)(xie)槽中(zhong)的間隙太(tai)(tai)大會使(shi)漏(lou)泄(xie)增加，太(tai)(tai)小(xiao)則葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)不能自由伸縮，會導致工作(zuo)失常。5．葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)的軸向間隙 對ηv影響(xiang)很(hen)(hen)大。1)小(xiao)型泵(beng)-0.015～0.03mm2)中(zhong)型泵(beng)-0.02～0.045mm6．油(you)(you)液的溫度(du)(du)和粘(zhan)度(du)(du) 一般不宜超過55℃，粘(zhan)度(du)(du)要求在17～37mm2/s之間。粘(zhan)度(du)(du)太(tai)(tai)大則吸(xi)(xi)油(you)(you)困(kun)難；粘(zhan)度(du)(du)太(tai)(tai)小(xiao)則漏(lou)泄(xie)嚴重。作(zuo)為泵(beng)產品，葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)更多地指滑片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)。葉(xie)(xie)片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)幾(ji)乎全部指滑片(pian)(pian)(pian)(pian)(pian)(pian)泵(beng)。
