在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使蕭縣機械密封摩(mo)擦端面(mian)尺寸精(jing)度提高(gao)，閥(fa)門的密(mi)封面(mian)，幾何(he)粗糙度和(he)表面(mian)粗糙度，但不能提高(gao)密(mi)封表面(mian)的相互位置(zhi)精(jing)度。

　　蕭縣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，隨著對蕭縣機械密封研(yan)(yan)究(jiu)(jiu)的(de)(de)復雜面(mian)(mian)(mian)，之間的(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)和(he)密(mi)(mi)(mi)封(feng)(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)究(jiu)(jiu)相(xiang)對(dui)運(yun)(yun)動(dong)(dong)時(shi)，密(mi)(mi)(mi)封(feng)(feng)圈(quan)(quan)(quan)(quan)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)，磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)究(jiu)(jiu)部(bu)分(fen)和(he)密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)(mian)之間的(de)(de)滑動(dong)(dong)或滾動(dong)(dong)，切斷(duan)密(mi)(mi)(mi)封(feng)(feng)圈(quan)(quan)(quan)(quan)上(shang)薄薄的(de)(de)一(yi)層金(jin)屬(shu)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)。密(mi)(mi)(mi)封(feng)(feng)凸峰部(bu)分(fen)的(de)(de)圈(quan)(quan)(quan)(quan)，表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)研(yan)(yan)磨(mo)(mo)(mo)，然后逐漸達到(dao)所要求(qiu)的(de)(de)幾何形狀。不僅是(shi)金(jin)屬(shu)磨(mo)(mo)(mo)料的(de)(de)研(yan)(yan)磨(mo)(mo)(mo)加(jia)工，以及化(hua)學作用。研(yan)(yan)磨(mo)(mo)(mo)油(you)可使(shi)加(jia)工表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)形成(cheng)的(de)(de)氧化(hua)膜，從而加(jia)快研(yan)(yan)磨(mo)(mo)(mo)過程。地面(mian)(mian)(mian)運(yun)(yun)動(dong)(dong)相(xiang)對(dui)運(yun)(yun)動(dong)(dong)的(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)和(he)密(mi)(mi)(mi)封(feng)(feng)圈(quan)(quan)(quan)(quan)密(mi)(mi)(mi)封(feng)(feng)圈(quan)(quan)(quan)(quan)的(de)(de)研(yan)(yan)究(jiu)(jiu)，對(dui)每個(ge)點的(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)上(shang)的(de)(de)道路和(he)相(xiang)對(dui)滑動(dong)(dong)的(de)(de)研(yan)(yan)究(jiu)(jiu)應該是(shi)一(yi)樣的(de)(de)。和(he)相(xiang)對(dui)運(yun)(yun)動(dong)(dong)方向(xiang)改(gai)變。改(gai)變密(mi)(mi)(mi)封(feng)(feng)環內的(de)(de)每個(ge)粒子的(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)上(shang)運(yun)(yun)動(dong)(dong)的(de)(de)方向(xiang)不會重復他們的(de)(de)軌跡，以避免磨(mo)(mo)(mo)損明顯增加(jia)了密(mi)(mi)(mi)封(feng)(feng)環的(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)粗糙度。此外，運(yun)(yun)動(dong)(dong)方向(xiang)的(de)(de)改(gai)變不能使(shi)磨(mo)(mo)(mo)粒分(fen)布比較均勻，且均勻切斷(duan)金(jin)屬(shu)密(mi)(mi)(mi)封(feng)(feng)環的(de)(de)表(biao)(biao)(biao)(biao)(biao)面(mian)(mian)(mian)。

　　蕭縣機械密封研(yan)(yan)(yan)磨(mo)(mo)(mo)是利用(yong)(yong)涂(tu)敷或者(zhe)壓(ya)嵌游離磨(mo)(mo)(mo)粒(li)(li)(li)與(yu)(yu)(yu)研(yan)(yan)(yan)磨(mo)(mo)(mo)劑(ji)的(de)(de)混合物(wu)(wu)，在(zai)一(yi)定剛性(xing)(xing)的(de)(de)軟質(zhi)研(yan)(yan)(yan)具上，通過(guo)研(yan)(yan)(yan)具與(yu)(yu)(yu)工(gong)件(jian)(jian)(jian)(jian)向(xiang)磨(mo)(mo)(mo)料(liao)施加(jia)(jia)一(yi)定壓(ya)力(li)(li)，磨(mo)(mo)(mo)料(liao)滾動(dong)與(yu)(yu)(yu)滑(hua)(hua)動(dong)，從被(bei)研(yan)(yan)(yan)磨(mo)(mo)(mo)工(gong)件(jian)(jian)(jian)(jian)上去除極薄的(de)(de)余量(liang)(liang)，以提高工(gong)件(jian)(jian)(jian)(jian)的(de)(de)精度(du)和降低表(biao)(biao)(biao)面(mian)(mian)(mian)粗(cu)糙度(du)值(zhi)得加(jia)(jia)工(gong)方法。按研(yan)(yan)(yan)磨(mo)(mo)(mo)時有無研(yan)(yan)(yan)磨(mo)(mo)(mo)液可分為干研(yan)(yan)(yan)與(yu)(yu)(yu)濕研(yan)(yan)(yan)。研(yan)(yan)(yan)磨(mo)(mo)(mo)過(guo)程中，在(zai)研(yan)(yan)(yan)磨(mo)(mo)(mo)壓(ya)力(li)(li)下(xia)，眾多的(de)(de)磨(mo)(mo)(mo)料(liao)微(wei)粒(li)(li)(li)進(jin)行(xing)(xing)(xing)微(wei)量(liang)(liang)切(qie)削。對(dui)工(gong)件(jian)(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)進(jin)行(xing)(xing)(xing)擠壓(ya)、刻劃、滑(hua)(hua)擦；在(zai)研(yan)(yan)(yan)具運動(dong)中當(dang)研(yan)(yan)(yan)具壓(ya)嵌的(de)(de)磨(mo)(mo)(mo)粒(li)(li)(li)脫落后及液中磨(mo)(mo)(mo)粒(li)(li)(li)相對(dui)工(gong)件(jian)(jian)(jian)(jian)發(fa)生(sheng)滾動(dong)。研(yan)(yan)(yan)磨(mo)(mo)(mo)過(guo)程中，在(zai)研(yan)(yan)(yan)磨(mo)(mo)(mo)壓(ya)力(li)(li)的(de)(de)作(zuo)用(yong)(yong)下(xia)，眾多磨(mo)(mo)(mo)粒(li)(li)(li)進(jin)行(xing)(xing)(xing)微(wei)量(liang)(liang)切(qie)削，同(tong)時被(bei)研(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)(mian)發(fa)生(sheng)微(wei)小起伏的(de)(de)塑性(xing)(xing)變形(xing)，并且被(bei)加(jia)(jia)入的(de)(de)諸如硬脂(zhi)(zhi)酸、油酸、脂(zhi)(zhi)肪(fang)酸等活性(xing)(xing)物(wu)(wu)質(zhi)與(yu)(yu)(yu)被(bei)研(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)(mian)起化學(xue)作(zuo)用(yong)(yong)。隨著研(yan)(yan)(yan)磨(mo)(mo)(mo)加(jia)(jia)工(gong)的(de)(de)進(jin)行(xing)(xing)(xing)，磨(mo)(mo)(mo)具與(yu)(yu)(yu)工(gong)件(jian)(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)間更趨貼近，其(qi)間充滿了(le)微(wei)屑與(yu)(yu)(yu)破碎磨(mo)(mo)(mo)料(liao)的(de)(de)碎渣，堵塞了(le)研(yan)(yan)(yan)具表(biao)(biao)(biao)面(mian)(mian)(mian)，對(dui)工(gong)件(jian)(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)起滑(hua)(hua)擦作(zuo)用(yong)(yong)。所以，研(yan)(yan)(yan)磨(mo)(mo)(mo)加(jia)(jia)工(gong)的(de)(de)實質(zhi)是磨(mo)(mo)(mo)粒(li)(li)(li)的(de)(de)微(wei)量(liang)(liang)切(qie)削、研(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)(mian)微(wei)小起伏的(de)(de)塑性(xing)(xing)流(liu)動(dong)、表(biao)(biao)(biao)面(mian)(mian)(mian)活性(xing)(xing)物(wu)(wu)質(zhi)的(de)(de)化學(xue)作(zuo)用(yong)(yong)及研(yan)(yan)(yan)具堵塞物(wu)(wu)與(yu)(yu)(yu)工(gong)件(jian)(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)(mian)滑(hua)(hua)擦作(zuo)用(yong)(yong)的(de)(de)綜(zong)合結果。

　　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蕭縣機械密封將熱(re)量傳給(gei)軸承(cheng)，使軸承(cheng)溫度升高。為了控制傳熱(re)，所以(yi)密封的水(shui)也起(qi)到冷卻作用。

　　蕭縣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蕭縣機械密封低壓側(ce)(大氣)將清水(shui)、蒸汽等冷(leng)卻(que)流體(ti)直接引入(ru)密(mi)(mi)封端(duan)泄露處的一種冷(leng)卻(que)方(fang)式(shi)，也稱急(ji)冷(leng)，急(ji)冷(leng)不僅冷(leng)卻(que)*，還能將密(mi)(mi)封端(duan)面(mian)周(zhou)圍的雜質及泄露液(ye)帶走，急(ji)冷(leng)液(ye)其(qi)壓力比密(mi)(mi)封介(jie)質壓力低。急(ji)冷(leng)液(ye)應盡(jin)量(liang)采(cai)用軟水(shui)，以防止(zhi)水(shui)垢產生(sheng)破壞密(mi)(mi)封端(duan)面(mian)。當(dang)密(mi)(mi)封流體(ti)為易凝固、易結(jie)晶時，可用蒸汽、溶劑等防止(zhi)流體(ti)凝結(jie)。
