在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使北海街道機械密封摩擦端面(mian)(mian)尺寸(cun)精度(du)提高，閥門(men)的密封面(mian)(mian)，幾何粗糙度(du)和表面(mian)(mian)粗糙度(du)，但(dan)不能提高密封表面(mian)(mian)的相互位(wei)置精度(du)。

　　北海街道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，隨著對北海街道機械密封研(yan)究的(de)(de)復(fu)雜面(mian)(mian)(mian)(mian)，之間的(de)(de)表面(mian)(mian)(mian)(mian)和密(mi)封(feng)(feng)(feng)磨(mo)料磨(mo)具研(yan)究相對(dui)(dui)運(yun)動(dong)(dong)時(shi)，密(mi)封(feng)(feng)(feng)圈表面(mian)(mian)(mian)(mian)，磨(mo)料磨(mo)具研(yan)究部(bu)分和密(mi)封(feng)(feng)(feng)面(mian)(mian)(mian)(mian)之間的(de)(de)滑(hua)動(dong)(dong)或滾動(dong)(dong)，切斷密(mi)封(feng)(feng)(feng)圈上(shang)(shang)薄(bo)(bo)薄(bo)(bo)的(de)(de)一層金屬表面(mian)(mian)(mian)(mian)。密(mi)封(feng)(feng)(feng)凸(tu)峰(feng)部(bu)分的(de)(de)圈，表面(mian)(mian)(mian)(mian)研(yan)磨(mo)，然后逐漸達到所要求的(de)(de)幾何形(xing)狀。不(bu)(bu)僅是(shi)(shi)金屬磨(mo)料的(de)(de)研(yan)磨(mo)加工(gong)(gong)，以及化(hua)學作用(yong)。研(yan)磨(mo)油可使加工(gong)(gong)表面(mian)(mian)(mian)(mian)形(xing)成的(de)(de)氧化(hua)膜，從而加快(kuai)研(yan)磨(mo)過程。地面(mian)(mian)(mian)(mian)運(yun)動(dong)(dong)相對(dui)(dui)運(yun)動(dong)(dong)的(de)(de)表面(mian)(mian)(mian)(mian)和密(mi)封(feng)(feng)(feng)圈密(mi)封(feng)(feng)(feng)圈的(de)(de)研(yan)究，對(dui)(dui)每個點的(de)(de)表面(mian)(mian)(mian)(mian)上(shang)(shang)的(de)(de)道路和相對(dui)(dui)滑(hua)動(dong)(dong)的(de)(de)研(yan)究應該是(shi)(shi)一樣(yang)的(de)(de)。和相對(dui)(dui)運(yun)動(dong)(dong)方(fang)(fang)向(xiang)(xiang)改變(bian)。改變(bian)密(mi)封(feng)(feng)(feng)環內(nei)的(de)(de)每個粒(li)子的(de)(de)表面(mian)(mian)(mian)(mian)上(shang)(shang)運(yun)動(dong)(dong)的(de)(de)方(fang)(fang)向(xiang)(xiang)不(bu)(bu)會重(zhong)復(fu)他們的(de)(de)軌跡，以避(bi)免磨(mo)損(sun)明(ming)顯增加了密(mi)封(feng)(feng)(feng)環的(de)(de)表面(mian)(mian)(mian)(mian)粗糙度。此外，運(yun)動(dong)(dong)方(fang)(fang)向(xiang)(xiang)的(de)(de)改變(bian)不(bu)(bu)能(neng)使磨(mo)粒(li)分布比較均勻，且均勻切斷金屬密(mi)封(feng)(feng)(feng)環的(de)(de)表面(mian)(mian)(mian)(mian)。

　　北海街道機械密封研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)是利用涂敷或者壓(ya)(ya)嵌游離(li)磨(mo)(mo)(mo)(mo)粒(li)(li)與研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)劑的(de)混合(he)(he)物(wu)(wu)，在一定(ding)剛性的(de)軟質(zhi)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)上(shang)，通過(guo)(guo)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)與工(gong)(gong)(gong)件(jian)(jian)(jian)向磨(mo)(mo)(mo)(mo)料施加一定(ding)壓(ya)(ya)力，磨(mo)(mo)(mo)(mo)料滾(gun)動(dong)(dong)與滑(hua)動(dong)(dong)，從被(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)工(gong)(gong)(gong)件(jian)(jian)(jian)上(shang)去除極(ji)薄的(de)余量(liang)(liang)(liang)，以提高工(gong)(gong)(gong)件(jian)(jian)(jian)的(de)精度(du)和降低表(biao)(biao)(biao)面(mian)(mian)粗(cu)糙度(du)值得加工(gong)(gong)(gong)方法。按(an)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)時有無研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)液可分為(wei)干研(yan)(yan)(yan)(yan)(yan)與濕研(yan)(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過(guo)(guo)程中，在研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)(ya)力下，眾多的(de)磨(mo)(mo)(mo)(mo)料微(wei)(wei)(wei)(wei)粒(li)(li)進行(xing)(xing)微(wei)(wei)(wei)(wei)量(liang)(liang)(liang)切削。對(dui)(dui)工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)進行(xing)(xing)擠(ji)壓(ya)(ya)、刻劃、滑(hua)擦；在研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)運動(dong)(dong)中當研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)壓(ya)(ya)嵌的(de)磨(mo)(mo)(mo)(mo)粒(li)(li)脫(tuo)落后及(ji)液中磨(mo)(mo)(mo)(mo)粒(li)(li)相對(dui)(dui)工(gong)(gong)(gong)件(jian)(jian)(jian)發生(sheng)滾(gun)動(dong)(dong)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過(guo)(guo)程中，在研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)(ya)力的(de)作用下，眾多磨(mo)(mo)(mo)(mo)粒(li)(li)進行(xing)(xing)微(wei)(wei)(wei)(wei)量(liang)(liang)(liang)切削，同時被(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)發生(sheng)微(wei)(wei)(wei)(wei)小(xiao)起(qi)伏的(de)塑性變(bian)形，并且被(bei)加入的(de)諸如(ru)硬(ying)脂酸(suan)(suan)、油酸(suan)(suan)、脂肪(fang)酸(suan)(suan)等活(huo)性物(wu)(wu)質(zhi)與被(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)起(qi)化學(xue)作用。隨著研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加工(gong)(gong)(gong)的(de)進行(xing)(xing)，磨(mo)(mo)(mo)(mo)具(ju)(ju)與工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)間(jian)更(geng)趨貼近(jin)，其間(jian)充(chong)滿了(le)微(wei)(wei)(wei)(wei)屑與破(po)碎(sui)磨(mo)(mo)(mo)(mo)料的(de)碎(sui)渣，堵(du)塞了(le)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)表(biao)(biao)(biao)面(mian)(mian)，對(dui)(dui)工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)起(qi)滑(hua)擦作用。所(suo)以，研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加工(gong)(gong)(gong)的(de)實質(zhi)是磨(mo)(mo)(mo)(mo)粒(li)(li)的(de)微(wei)(wei)(wei)(wei)量(liang)(liang)(liang)切削、研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)微(wei)(wei)(wei)(wei)小(xiao)起(qi)伏的(de)塑性流(liu)動(dong)(dong)、表(biao)(biao)(biao)面(mian)(mian)活(huo)性物(wu)(wu)質(zhi)的(de)化學(xue)作用及(ji)研(yan)(yan)(yan)(yan)(yan)具(ju)(ju)堵(du)塞物(wu)(wu)與工(gong)(gong)(gong)件(jian)(jian)(jian)表(biao)(biao)(biao)面(mian)(mian)滑(hua)擦作用的(de)綜合(he)(he)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北海街道機械密封將熱量(liang)傳給軸承，使軸承溫(wen)度升高(gao)。為(wei)了(le)控制傳熱，所以密封(feng)的水(shui)也起(qi)到冷卻作用。

　　北海街道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北海街道機械密封低壓側(ce)(大氣)將清(qing)水、蒸(zheng)汽等冷卻流(liu)體直接引入(ru)密(mi)封(feng)端泄(xie)露處的(de)(de)一種(zhong)冷卻方式，也稱急(ji)(ji)(ji)冷，急(ji)(ji)(ji)冷不僅冷卻*，還能(neng)將密(mi)封(feng)端面周圍的(de)(de)雜質(zhi)及泄(xie)露液帶走，急(ji)(ji)(ji)冷液其壓力比密(mi)封(feng)介質(zhi)壓力低。急(ji)(ji)(ji)冷液應盡量采用(yong)(yong)軟水，以防止(zhi)(zhi)水垢產生破壞密(mi)封(feng)端面。當密(mi)封(feng)流(liu)體為易凝固、易結晶時，可用(yong)(yong)蒸(zheng)汽、溶劑等防止(zhi)(zhi)流(liu)體凝結。
