在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使金華機械密封摩擦端面尺寸精(jing)度(du)提高(gao)，閥門(men)的密封面，幾何粗糙度(du)和表(biao)面粗糙度(du)，但(dan)不能提高(gao)密封表(biao)面的相互位置精(jing)度(du)。

　　金華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，隨著對金華機械密封研究(jiu)(jiu)的(de)(de)(de)(de)(de)(de)復雜面(mian)(mian)，之間的(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)和密(mi)(mi)封(feng)(feng)磨(mo)料磨(mo)具研究(jiu)(jiu)相對(dui)運(yun)(yun)動(dong)時，密(mi)(mi)封(feng)(feng)圈(quan)表(biao)(biao)(biao)面(mian)(mian)，磨(mo)料磨(mo)具研究(jiu)(jiu)部分和密(mi)(mi)封(feng)(feng)面(mian)(mian)之間的(de)(de)(de)(de)(de)(de)滑(hua)動(dong)或(huo)滾動(dong)，切斷密(mi)(mi)封(feng)(feng)圈(quan)上薄(bo)薄(bo)的(de)(de)(de)(de)(de)(de)一層金屬表(biao)(biao)(biao)面(mian)(mian)。密(mi)(mi)封(feng)(feng)凸峰部分的(de)(de)(de)(de)(de)(de)圈(quan)，表(biao)(biao)(biao)面(mian)(mian)研磨(mo)，然后逐漸達到所要求的(de)(de)(de)(de)(de)(de)幾何(he)形狀。不(bu)僅是金屬磨(mo)料的(de)(de)(de)(de)(de)(de)研磨(mo)加(jia)工(gong)，以(yi)及化學作用。研磨(mo)油可使加(jia)工(gong)表(biao)(biao)(biao)面(mian)(mian)形成的(de)(de)(de)(de)(de)(de)氧(yang)化膜，從(cong)而加(jia)快研磨(mo)過程。地面(mian)(mian)運(yun)(yun)動(dong)相對(dui)運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)和密(mi)(mi)封(feng)(feng)圈(quan)密(mi)(mi)封(feng)(feng)圈(quan)的(de)(de)(de)(de)(de)(de)研究(jiu)(jiu)，對(dui)每(mei)個點的(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)上的(de)(de)(de)(de)(de)(de)道路和相對(dui)滑(hua)動(dong)的(de)(de)(de)(de)(de)(de)研究(jiu)(jiu)應該是一樣的(de)(de)(de)(de)(de)(de)。和相對(dui)運(yun)(yun)動(dong)方向(xiang)改(gai)變(bian)(bian)。改(gai)變(bian)(bian)密(mi)(mi)封(feng)(feng)環內的(de)(de)(de)(de)(de)(de)每(mei)個粒(li)子的(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)上運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)(de)方向(xiang)不(bu)會重復他(ta)們的(de)(de)(de)(de)(de)(de)軌跡，以(yi)避免(mian)磨(mo)損明顯(xian)增加(jia)了(le)密(mi)(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)粗糙度。此外，運(yun)(yun)動(dong)方向(xiang)的(de)(de)(de)(de)(de)(de)改(gai)變(bian)(bian)不(bu)能使磨(mo)粒(li)分布(bu)比較均勻(yun)，且均勻(yun)切斷金屬密(mi)(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)。

　　金華機械密封研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)是利用(yong)(yong)涂敷或者壓(ya)(ya)嵌(qian)游(you)離磨(mo)(mo)(mo)(mo)粒與(yu)研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)劑的(de)(de)混合物，在一定(ding)(ding)剛性(xing)(xing)(xing)(xing)的(de)(de)軟(ruan)質研(yan)(yan)(yan)(yan)(yan)(yan)(yan)具(ju)上(shang)，通(tong)過(guo)研(yan)(yan)(yan)(yan)(yan)(yan)(yan)具(ju)與(yu)工(gong)件向磨(mo)(mo)(mo)(mo)料(liao)(liao)施加(jia)(jia)一定(ding)(ding)壓(ya)(ya)力，磨(mo)(mo)(mo)(mo)料(liao)(liao)滾(gun)動(dong)(dong)(dong)與(yu)滑(hua)動(dong)(dong)(dong)，從被(bei)研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)工(gong)件上(shang)去除極薄的(de)(de)余量，以提高工(gong)件的(de)(de)精度(du)和(he)降低(di)表(biao)(biao)面(mian)(mian)粗糙(cao)度(du)值得加(jia)(jia)工(gong)方法(fa)。按研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)時(shi)有(you)無研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)液可分為(wei)干研(yan)(yan)(yan)(yan)(yan)(yan)(yan)與(yu)濕(shi)研(yan)(yan)(yan)(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過(guo)程(cheng)中(zhong)，在研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)(ya)力下(xia)，眾多的(de)(de)磨(mo)(mo)(mo)(mo)料(liao)(liao)微(wei)(wei)粒進行微(wei)(wei)量切(qie)(qie)削(xue)。對工(gong)件表(biao)(biao)面(mian)(mian)進行擠壓(ya)(ya)、刻(ke)劃、滑(hua)擦；在研(yan)(yan)(yan)(yan)(yan)(yan)(yan)具(ju)運(yun)動(dong)(dong)(dong)中(zhong)當研(yan)(yan)(yan)(yan)(yan)(yan)(yan)具(ju)壓(ya)(ya)嵌(qian)的(de)(de)磨(mo)(mo)(mo)(mo)粒脫落后及液中(zhong)磨(mo)(mo)(mo)(mo)粒相對工(gong)件發生滾(gun)動(dong)(dong)(dong)。研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過(guo)程(cheng)中(zhong)，在研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)(ya)力的(de)(de)作(zuo)用(yong)(yong)下(xia)，眾多磨(mo)(mo)(mo)(mo)粒進行微(wei)(wei)量切(qie)(qie)削(xue)，同時(shi)被(bei)研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)面(mian)(mian)發生微(wei)(wei)小起(qi)(qi)(qi)伏的(de)(de)塑(su)性(xing)(xing)(xing)(xing)變形，并且被(bei)加(jia)(jia)入(ru)的(de)(de)諸(zhu)如硬脂(zhi)酸(suan)(suan)、油酸(suan)(suan)、脂(zhi)肪酸(suan)(suan)等(deng)活(huo)性(xing)(xing)(xing)(xing)物質與(yu)被(bei)研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)面(mian)(mian)起(qi)(qi)(qi)化(hua)學(xue)作(zuo)用(yong)(yong)。隨著研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加(jia)(jia)工(gong)的(de)(de)進行，磨(mo)(mo)(mo)(mo)具(ju)與(yu)工(gong)件表(biao)(biao)面(mian)(mian)間更趨貼近，其間充滿了微(wei)(wei)屑與(yu)破碎(sui)(sui)磨(mo)(mo)(mo)(mo)料(liao)(liao)的(de)(de)碎(sui)(sui)渣，堵(du)塞了研(yan)(yan)(yan)(yan)(yan)(yan)(yan)具(ju)表(biao)(biao)面(mian)(mian)，對工(gong)件表(biao)(biao)面(mian)(mian)起(qi)(qi)(qi)滑(hua)擦作(zuo)用(yong)(yong)。所以，研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加(jia)(jia)工(gong)的(de)(de)實(shi)質是磨(mo)(mo)(mo)(mo)粒的(de)(de)微(wei)(wei)量切(qie)(qie)削(xue)、研(yan)(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)面(mian)(mian)微(wei)(wei)小起(qi)(qi)(qi)伏的(de)(de)塑(su)性(xing)(xing)(xing)(xing)流(liu)動(dong)(dong)(dong)、表(biao)(biao)面(mian)(mian)活(huo)性(xing)(xing)(xing)(xing)物質的(de)(de)化(hua)學(xue)作(zuo)用(yong)(yong)及研(yan)(yan)(yan)(yan)(yan)(yan)(yan)具(ju)堵(du)塞物與(yu)工(gong)件表(biao)(biao)面(mian)(mian)滑(hua)擦作(zuo)用(yong)(yong)的(de)(de)綜(zong)合結果(guo)。

　　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金華機械密封將熱(re)量傳給軸承，使(shi)軸承溫度升高。為(wei)了控(kong)制傳熱(re)，所以密封的水也起到冷卻作用。

　　金華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金華機械密封低壓(ya)側(ce)(大氣)將清水、蒸(zheng)汽等冷(leng)(leng)卻流(liu)(liu)體(ti)(ti)直接引入密(mi)封(feng)(feng)端泄露處的一種冷(leng)(leng)卻方式，也稱急(ji)冷(leng)(leng)，急(ji)冷(leng)(leng)不僅(jin)冷(leng)(leng)卻*，還(huan)能(neng)將密(mi)封(feng)(feng)端面周圍的雜質及(ji)泄露液帶走，急(ji)冷(leng)(leng)液其壓(ya)力比密(mi)封(feng)(feng)介(jie)質壓(ya)力低。急(ji)冷(leng)(leng)液應盡量(liang)采用軟水，以防止水垢產(chan)生破壞密(mi)封(feng)(feng)端面。當密(mi)封(feng)(feng)流(liu)(liu)體(ti)(ti)為(wei)易凝(ning)固、易結晶時，可(ke)用蒸(zheng)汽、溶劑等防止流(liu)(liu)體(ti)(ti)凝(ning)結。
