在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使瀘定機械密封摩(mo)擦端面尺(chi)寸(cun)精度(du)(du)(du)提高(gao)，閥門的密封面，幾何粗(cu)糙(cao)度(du)(du)(du)和(he)表(biao)面粗(cu)糙(cao)度(du)(du)(du)，但(dan)不能提高(gao)密封表(biao)面的相互位置精度(du)(du)(du)。

　　瀘定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，隨著對瀘定機械密封研(yan)究(jiu)的(de)(de)(de)(de)復(fu)雜(za)面(mian)(mian)(mian)，之(zhi)間(jian)的(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)和(he)(he)密(mi)封(feng)(feng)(feng)(feng)磨(mo)(mo)(mo)(mo)料磨(mo)(mo)(mo)(mo)具(ju)研(yan)究(jiu)相(xiang)對(dui)運(yun)(yun)(yun)動(dong)(dong)時，密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)表(biao)面(mian)(mian)(mian)，磨(mo)(mo)(mo)(mo)料磨(mo)(mo)(mo)(mo)具(ju)研(yan)究(jiu)部(bu)分(fen)和(he)(he)密(mi)封(feng)(feng)(feng)(feng)面(mian)(mian)(mian)之(zhi)間(jian)的(de)(de)(de)(de)滑動(dong)(dong)或(huo)滾(gun)動(dong)(dong)，切斷密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)上薄(bo)(bo)薄(bo)(bo)的(de)(de)(de)(de)一層金屬(shu)表(biao)面(mian)(mian)(mian)。密(mi)封(feng)(feng)(feng)(feng)凸峰部(bu)分(fen)的(de)(de)(de)(de)圈(quan)(quan)，表(biao)面(mian)(mian)(mian)研(yan)磨(mo)(mo)(mo)(mo)，然后逐漸達到所(suo)要(yao)求的(de)(de)(de)(de)幾何(he)形狀(zhuang)。不僅是金屬(shu)磨(mo)(mo)(mo)(mo)料的(de)(de)(de)(de)研(yan)磨(mo)(mo)(mo)(mo)加工，以及化(hua)學作用。研(yan)磨(mo)(mo)(mo)(mo)油可(ke)使(shi)加工表(biao)面(mian)(mian)(mian)形成的(de)(de)(de)(de)氧化(hua)膜，從而(er)加快研(yan)磨(mo)(mo)(mo)(mo)過程。地面(mian)(mian)(mian)運(yun)(yun)(yun)動(dong)(dong)相(xiang)對(dui)運(yun)(yun)(yun)動(dong)(dong)的(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)和(he)(he)密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)密(mi)封(feng)(feng)(feng)(feng)圈(quan)(quan)的(de)(de)(de)(de)研(yan)究(jiu)，對(dui)每個點的(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)上的(de)(de)(de)(de)道路和(he)(he)相(xiang)對(dui)滑動(dong)(dong)的(de)(de)(de)(de)研(yan)究(jiu)應該是一樣(yang)的(de)(de)(de)(de)。和(he)(he)相(xiang)對(dui)運(yun)(yun)(yun)動(dong)(dong)方向改(gai)變(bian)。改(gai)變(bian)密(mi)封(feng)(feng)(feng)(feng)環(huan)內(nei)的(de)(de)(de)(de)每個粒子的(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)上運(yun)(yun)(yun)動(dong)(dong)的(de)(de)(de)(de)方向不會重復(fu)他們的(de)(de)(de)(de)軌跡，以避免磨(mo)(mo)(mo)(mo)損(sun)明顯增(zeng)加了(le)密(mi)封(feng)(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)粗糙度。此外，運(yun)(yun)(yun)動(dong)(dong)方向的(de)(de)(de)(de)改(gai)變(bian)不能使(shi)磨(mo)(mo)(mo)(mo)粒分(fen)布比(bi)較均勻(yun)(yun)，且均勻(yun)(yun)切斷金屬(shu)密(mi)封(feng)(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)。

　　瀘定機械密封研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)是利(li)用(yong)(yong)涂敷或者壓嵌(qian)游離磨(mo)(mo)(mo)粒與研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)劑的(de)(de)(de)混合物(wu)，在(zai)一(yi)定剛(gang)性的(de)(de)(de)軟質(zhi)研(yan)(yan)(yan)(yan)具上(shang)，通過研(yan)(yan)(yan)(yan)具與工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)向磨(mo)(mo)(mo)料(liao)(liao)施加(jia)一(yi)定壓力，磨(mo)(mo)(mo)料(liao)(liao)滾動(dong)(dong)與滑(hua)(hua)動(dong)(dong)，從被研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)上(shang)去除極薄的(de)(de)(de)余量，以提高工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的(de)(de)(de)精度和降低表(biao)面粗糙(cao)度值(zhi)得加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)方(fang)法。按研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)時有(you)無研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)液(ye)可分(fen)為干(gan)研(yan)(yan)(yan)(yan)與濕研(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)過程中，在(zai)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)壓力下，眾(zhong)多的(de)(de)(de)磨(mo)(mo)(mo)料(liao)(liao)微(wei)粒進(jin)行(xing)微(wei)量切削。對(dui)(dui)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)表(biao)面進(jin)行(xing)擠壓、刻劃(hua)、滑(hua)(hua)擦；在(zai)研(yan)(yan)(yan)(yan)具運動(dong)(dong)中當研(yan)(yan)(yan)(yan)具壓嵌(qian)的(de)(de)(de)磨(mo)(mo)(mo)粒脫落后(hou)及液(ye)中磨(mo)(mo)(mo)粒相對(dui)(dui)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)發生(sheng)滾動(dong)(dong)。研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)過程中，在(zai)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)壓力的(de)(de)(de)作用(yong)(yong)下，眾(zhong)多磨(mo)(mo)(mo)粒進(jin)行(xing)微(wei)量切削，同時被研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)面發生(sheng)微(wei)小(xiao)起(qi)伏的(de)(de)(de)塑性變形，并且被加(jia)入的(de)(de)(de)諸(zhu)如硬脂酸、油酸、脂肪酸等(deng)活性物(wu)質(zhi)與被研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)面起(qi)化學作用(yong)(yong)。隨著(zhu)研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)進(jin)行(xing)，磨(mo)(mo)(mo)具與工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)表(biao)面間更趨貼近，其間充滿了微(wei)屑與破碎磨(mo)(mo)(mo)料(liao)(liao)的(de)(de)(de)碎渣，堵塞了研(yan)(yan)(yan)(yan)具表(biao)面，對(dui)(dui)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)表(biao)面起(qi)滑(hua)(hua)擦作用(yong)(yong)。所以，研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)的(de)(de)(de)實(shi)質(zhi)是磨(mo)(mo)(mo)粒的(de)(de)(de)微(wei)量切削、研(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)表(biao)面微(wei)小(xiao)起(qi)伏的(de)(de)(de)塑性流動(dong)(dong)、表(biao)面活性物(wu)質(zhi)的(de)(de)(de)化學作用(yong)(yong)及研(yan)(yan)(yan)(yan)具堵塞物(wu)與工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)表(biao)面滑(hua)(hua)擦作用(yong)(yong)的(de)(de)(de)綜合結果。

　　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瀘定機械密封將熱量(liang)傳(chuan)給軸(zhou)承，使軸(zhou)承溫度升高。為了(le)控制傳(chuan)熱，所以密封的水也起到冷(leng)卻(que)作(zuo)用。

　　瀘定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瀘定機械密封低(di)(di)壓(ya)(ya)側(大氣)將(jiang)清水、蒸汽等(deng)(deng)冷(leng)卻流(liu)體(ti)(ti)直(zhi)接引入密封(feng)端(duan)(duan)(duan)泄(xie)露處的一種冷(leng)卻方式，也稱(cheng)急冷(leng)，急冷(leng)不僅冷(leng)卻*，還能將(jiang)密封(feng)端(duan)(duan)(duan)面周圍的雜質及泄(xie)露液(ye)(ye)帶走(zou)，急冷(leng)液(ye)(ye)其壓(ya)(ya)力比(bi)密封(feng)介質壓(ya)(ya)力低(di)(di)。急冷(leng)液(ye)(ye)應盡量采用軟(ruan)水，以防止(zhi)(zhi)水垢產生破壞密封(feng)端(duan)(duan)(duan)面。當密封(feng)流(liu)體(ti)(ti)為易(yi)凝固、易(yi)結晶時，可(ke)用蒸汽、溶劑等(deng)(deng)防止(zhi)(zhi)流(liu)體(ti)(ti)凝結。
