在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使市中機械密封摩擦端面(mian)尺寸精(jing)度提高(gao)，閥門(men)的密封面(mian)，幾何粗(cu)糙(cao)度和表面(mian)粗(cu)糙(cao)度，但(dan)不能提高(gao)密封表面(mian)的相互位置精(jing)度。

　　市中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，隨著對市中機械密封研(yan)(yan)究的(de)(de)(de)復雜面(mian)，之間(jian)(jian)的(de)(de)(de)表(biao)(biao)面(mian)和(he)(he)密(mi)(mi)(mi)封(feng)(feng)(feng)磨(mo)(mo)料磨(mo)(mo)具(ju)研(yan)(yan)究相(xiang)對運(yun)動(dong)時，密(mi)(mi)(mi)封(feng)(feng)(feng)圈表(biao)(biao)面(mian)，磨(mo)(mo)料磨(mo)(mo)具(ju)研(yan)(yan)究部分(fen)和(he)(he)密(mi)(mi)(mi)封(feng)(feng)(feng)面(mian)之間(jian)(jian)的(de)(de)(de)滑動(dong)或滾動(dong)，切斷(duan)密(mi)(mi)(mi)封(feng)(feng)(feng)圈上(shang)(shang)薄薄的(de)(de)(de)一(yi)(yi)層金屬(shu)表(biao)(biao)面(mian)。密(mi)(mi)(mi)封(feng)(feng)(feng)凸峰(feng)部分(fen)的(de)(de)(de)圈，表(biao)(biao)面(mian)研(yan)(yan)磨(mo)(mo)，然后逐漸達到所要求的(de)(de)(de)幾何形(xing)(xing)狀(zhuang)。不僅是(shi)金屬(shu)磨(mo)(mo)料的(de)(de)(de)研(yan)(yan)磨(mo)(mo)加(jia)工，以及化學(xue)作用。研(yan)(yan)磨(mo)(mo)油可使加(jia)工表(biao)(biao)面(mian)形(xing)(xing)成的(de)(de)(de)氧化膜，從而加(jia)快(kuai)研(yan)(yan)磨(mo)(mo)過程。地面(mian)運(yun)動(dong)相(xiang)對運(yun)動(dong)的(de)(de)(de)表(biao)(biao)面(mian)和(he)(he)密(mi)(mi)(mi)封(feng)(feng)(feng)圈密(mi)(mi)(mi)封(feng)(feng)(feng)圈的(de)(de)(de)研(yan)(yan)究，對每(mei)個(ge)點的(de)(de)(de)表(biao)(biao)面(mian)上(shang)(shang)的(de)(de)(de)道(dao)路和(he)(he)相(xiang)對滑動(dong)的(de)(de)(de)研(yan)(yan)究應(ying)該(gai)是(shi)一(yi)(yi)樣的(de)(de)(de)。和(he)(he)相(xiang)對運(yun)動(dong)方向(xiang)改(gai)變(bian)(bian)。改(gai)變(bian)(bian)密(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)內的(de)(de)(de)每(mei)個(ge)粒子的(de)(de)(de)表(biao)(biao)面(mian)上(shang)(shang)運(yun)動(dong)的(de)(de)(de)方向(xiang)不會(hui)重復他(ta)們的(de)(de)(de)軌跡，以避(bi)免磨(mo)(mo)損明顯增加(jia)了密(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)的(de)(de)(de)表(biao)(biao)面(mian)粗糙(cao)度(du)。此外，運(yun)動(dong)方向(xiang)的(de)(de)(de)改(gai)變(bian)(bian)不能(neng)使磨(mo)(mo)粒分(fen)布比較(jiao)均(jun)勻(yun)(yun)，且均(jun)勻(yun)(yun)切斷(duan)金屬(shu)密(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)的(de)(de)(de)表(biao)(biao)面(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市中機械密封將(jiang)熱量傳給軸承，使軸承溫度升高。為了控(kong)制(zhi)傳熱，所以(yi)密封的水(shui)也(ye)起(qi)到冷卻作用。

　　市中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市中機械密封低壓(ya)(ya)(ya)側(大氣)將(jiang)清(qing)水、蒸汽(qi)等冷(leng)(leng)卻(que)流體(ti)直接引(yin)入密(mi)(mi)封(feng)(feng)端(duan)泄露處(chu)的一種(zhong)冷(leng)(leng)卻(que)方式，也稱急冷(leng)(leng)，急冷(leng)(leng)不(bu)僅冷(leng)(leng)卻(que)*，還能將(jiang)密(mi)(mi)封(feng)(feng)端(duan)面周圍的雜(za)質(zhi)及泄露液(ye)帶走，急冷(leng)(leng)液(ye)其(qi)壓(ya)(ya)(ya)力(li)(li)比密(mi)(mi)封(feng)(feng)介質(zhi)壓(ya)(ya)(ya)力(li)(li)低。急冷(leng)(leng)液(ye)應(ying)盡量采用軟水，以防止水垢產生破壞密(mi)(mi)封(feng)(feng)端(duan)面。當(dang)密(mi)(mi)封(feng)(feng)流體(ti)為易凝固、易結晶時，可用蒸汽(qi)、溶劑等防止流體(ti)凝結。
