在研磨過程中,閥門制造的密封面是一個常用的整理方法,可以使阿圖什機械密封摩擦端面(mian)尺寸精度(du)提高(gao),閥(fa)門的密(mi)封面(mian),幾何粗糙(cao)度(du)和表面(mian)粗糙(cao)度(du),但不能提高(gao)密(mi)封表面(mian)的相互位置(zhi)精度(du)。
阿圖什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,隨著對阿圖什機械密封研(yan)究的(de)(de)(de)(de)(de)(de)(de)復(fu)雜(za)面(mian)(mian),之間的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)(mian)和(he)密(mi)(mi)封磨(mo)(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)(mo)具(ju)研(yan)究相對(dui)(dui)運(yun)(yun)動(dong)時,密(mi)(mi)封圈(quan)(quan)(quan)表(biao)(biao)(biao)(biao)面(mian)(mian),磨(mo)(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)(mo)具(ju)研(yan)究部分(fen)和(he)密(mi)(mi)封面(mian)(mian)之間的(de)(de)(de)(de)(de)(de)(de)滑(hua)動(dong)或滾(gun)動(dong),切斷密(mi)(mi)封圈(quan)(quan)(quan)上薄薄的(de)(de)(de)(de)(de)(de)(de)一層金(jin)屬(shu)表(biao)(biao)(biao)(biao)面(mian)(mian)。密(mi)(mi)封凸峰部分(fen)的(de)(de)(de)(de)(de)(de)(de)圈(quan)(quan)(quan),表(biao)(biao)(biao)(biao)面(mian)(mian)研(yan)磨(mo)(mo)(mo)(mo),然后逐(zhu)漸達(da)到所要(yao)求(qiu)的(de)(de)(de)(de)(de)(de)(de)幾何形狀。不(bu)僅是(shi)金(jin)屬(shu)磨(mo)(mo)(mo)(mo)料(liao)的(de)(de)(de)(de)(de)(de)(de)研(yan)磨(mo)(mo)(mo)(mo)加工,以(yi)及化學作(zuo)用(yong)。研(yan)磨(mo)(mo)(mo)(mo)油可(ke)使(shi)加工表(biao)(biao)(biao)(biao)面(mian)(mian)形成的(de)(de)(de)(de)(de)(de)(de)氧化膜(mo),從而加快(kuai)研(yan)磨(mo)(mo)(mo)(mo)過程。地(di)面(mian)(mian)運(yun)(yun)動(dong)相對(dui)(dui)運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)(mian)和(he)密(mi)(mi)封圈(quan)(quan)(quan)密(mi)(mi)封圈(quan)(quan)(quan)的(de)(de)(de)(de)(de)(de)(de)研(yan)究,對(dui)(dui)每(mei)個點(dian)的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)(mian)上的(de)(de)(de)(de)(de)(de)(de)道路和(he)相對(dui)(dui)滑(hua)動(dong)的(de)(de)(de)(de)(de)(de)(de)研(yan)究應該(gai)是(shi)一樣的(de)(de)(de)(de)(de)(de)(de)。和(he)相對(dui)(dui)運(yun)(yun)動(dong)方向改變。改變密(mi)(mi)封環內(nei)的(de)(de)(de)(de)(de)(de)(de)每(mei)個粒子的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)(mian)上運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)(de)(de)方向不(bu)會重復(fu)他們的(de)(de)(de)(de)(de)(de)(de)軌(gui)跡,以(yi)避免磨(mo)(mo)(mo)(mo)損明顯增加了密(mi)(mi)封環的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)(mian)粗糙(cao)度。此(ci)外,運(yun)(yun)動(dong)方向的(de)(de)(de)(de)(de)(de)(de)改變不(bu)能(neng)使(shi)磨(mo)(mo)(mo)(mo)粒分(fen)布比較均(jun)勻(yun),且均(jun)勻(yun)切斷金(jin)屬(shu)密(mi)(mi)封環的(de)(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)(biao)面(mian)(mian)。

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阿圖什機械密封將熱量傳給軸(zhou)承(cheng),使(shi)軸(zhou)承(cheng)溫(wen)度升高(gao)。為了控制(zhi)傳熱,所以密封的水也起(qi)到冷卻作用。
阿圖什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阿圖什機械密封低(di)壓側(大氣)將清水(shui)、蒸汽等(deng)冷(leng)(leng)(leng)(leng)卻流(liu)體(ti)直接(jie)引入(ru)密(mi)封端泄露(lu)處的一(yi)種(zhong)冷(leng)(leng)(leng)(leng)卻方式(shi),也(ye)稱急(ji)冷(leng)(leng)(leng)(leng),急(ji)冷(leng)(leng)(leng)(leng)不僅冷(leng)(leng)(leng)(leng)卻*,還能將密(mi)封端面周圍(wei)的雜質(zhi)及泄露(lu)液(ye)帶走,急(ji)冷(leng)(leng)(leng)(leng)液(ye)其(qi)壓力比密(mi)封介質(zhi)壓力低(di)。急(ji)冷(leng)(leng)(leng)(leng)液(ye)應盡(jin)量采用(yong)軟水(shui),以(yi)防(fang)止水(shui)垢產(chan)生破(po)壞密(mi)封端面。當密(mi)封流(liu)體(ti)為易凝固、易結晶時,可用(yong)蒸汽、溶劑等(deng)防(fang)止流(liu)體(ti)凝結。
