中陽研磨和冷卻對密封面都非常重要

發(fa)布時(shi)間:2021-12-17 11:54:31 人(ren)氣:93807 來(lai)源(yuan):

  在研磨過程中,閥門制造的密封面是一個常用的整理方法,可以使中陽機械密封摩擦端面(mian)尺寸精度提高(gao),閥門的密封(feng)面(mian),幾何(he)粗(cu)糙度和表面(mian)粗(cu)糙度,但不能提高(gao)密封(feng)表面(mian)的相互位置精度。


  中陽機械密封面研磨包括五個方面的基本原理:研磨運動、研磨工藝、研磨速度、研磨壓力和研磨余量。研磨過程好一起研究密封面,隨著對中陽機械密封研(yan)(yan)究的(de)(de)(de)(de)(de)復(fu)雜面,之間(jian)的(de)(de)(de)(de)(de)表(biao)(biao)面和密封(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)(ju)研(yan)(yan)究相(xiang)(xiang)對運(yun)(yun)(yun)動(dong)(dong)(dong)時,密封(feng)圈(quan)(quan)(quan)表(biao)(biao)面,磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)(ju)研(yan)(yan)究部(bu)分和密封(feng)面之間(jian)的(de)(de)(de)(de)(de)滑動(dong)(dong)(dong)或滾動(dong)(dong)(dong),切(qie)斷(duan)密封(feng)圈(quan)(quan)(quan)上薄薄的(de)(de)(de)(de)(de)一層(ceng)金(jin)屬(shu)表(biao)(biao)面。密封(feng)凸峰(feng)部(bu)分的(de)(de)(de)(de)(de)圈(quan)(quan)(quan),表(biao)(biao)面研(yan)(yan)磨(mo)(mo)(mo),然后逐漸達到所要求(qiu)的(de)(de)(de)(de)(de)幾何形(xing)狀。不僅是金(jin)屬(shu)磨(mo)(mo)(mo)料的(de)(de)(de)(de)(de)研(yan)(yan)磨(mo)(mo)(mo)加工(gong),以(yi)及化學作用。研(yan)(yan)磨(mo)(mo)(mo)油可使加工(gong)表(biao)(biao)面形(xing)成的(de)(de)(de)(de)(de)氧(yang)化膜,從而加快研(yan)(yan)磨(mo)(mo)(mo)過程(cheng)。地面運(yun)(yun)(yun)動(dong)(dong)(dong)相(xiang)(xiang)對運(yun)(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)表(biao)(biao)面和密封(feng)圈(quan)(quan)(quan)密封(feng)圈(quan)(quan)(quan)的(de)(de)(de)(de)(de)研(yan)(yan)究,對每(mei)(mei)個點的(de)(de)(de)(de)(de)表(biao)(biao)面上的(de)(de)(de)(de)(de)道路和相(xiang)(xiang)對滑動(dong)(dong)(dong)的(de)(de)(de)(de)(de)研(yan)(yan)究應該是一樣的(de)(de)(de)(de)(de)。和相(xiang)(xiang)對運(yun)(yun)(yun)動(dong)(dong)(dong)方(fang)向(xiang)改(gai)變。改(gai)變密封(feng)環(huan)內的(de)(de)(de)(de)(de)每(mei)(mei)個粒子的(de)(de)(de)(de)(de)表(biao)(biao)面上運(yun)(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)方(fang)向(xiang)不會重復(fu)他們的(de)(de)(de)(de)(de)軌跡,以(yi)避免磨(mo)(mo)(mo)損明顯增加了密封(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)(biao)面粗(cu)糙(cao)度(du)。此(ci)外,運(yun)(yun)(yun)動(dong)(dong)(dong)方(fang)向(xiang)的(de)(de)(de)(de)(de)改(gai)變不能使磨(mo)(mo)(mo)粒分布(bu)比較均勻,且均勻切(qie)斷(duan)金(jin)屬(shu)密封(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)(biao)面。

  為了不讓泵水通過軸與密封間隙泄漏,由出口冷凝泵或在鹽水中的母管引至密封水。給水泵是一種具有一定溫度、高溫的水通過泵軸或泵體金屬容器用中陽機械密封將(jiang)熱(re)量傳(chuan)給軸(zhou)承,使軸(zhou)承溫度升高。為了控制傳(chuan)熱(re),所(suo)以密封的水(shui)也起到冷卻(que)作用。


  中陽機械密封直接冷卻就是冷卻液體直接和密封端面接觸達到冷卻的目的。沖洗實際上也是直接冷卻的一種方式,沖洗方式中通過管路連接換熱器將冷卻后的沖洗液引入密封腔進行直接冷卻。還有一種直接冷卻就是在中陽機械密封低(di)壓(ya)(ya)側(大氣(qi))將清水、蒸汽(qi)等冷(leng)(leng)卻(que)(que)流體(ti)直接引入(ru)密封(feng)端(duan)泄露(lu)處的一種冷(leng)(leng)卻(que)(que)方式(shi),也稱急冷(leng)(leng),急冷(leng)(leng)不僅冷(leng)(leng)卻(que)(que)*,還能(neng)將密封(feng)端(duan)面周圍的雜質及泄露(lu)液(ye)帶走,急冷(leng)(leng)液(ye)其(qi)壓(ya)(ya)力比密封(feng)介質壓(ya)(ya)力低(di)。急冷(leng)(leng)液(ye)應盡量采用(yong)軟水,以防止水垢產生破(po)壞密封(feng)端(duan)面。當密封(feng)流體(ti)為易凝固、易結晶時,可用(yong)蒸汽(qi)、溶劑等防止流體(ti)凝結。
