在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使天寧機械密封摩擦端面尺寸(cun)精度(du)提高，閥門的(de)密封面，幾何(he)粗糙度(du)和表面粗糙度(du)，但(dan)不(bu)能提高密封表面的(de)相互位(wei)置精度(du)。

　　天寧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，隨著對天寧機械密封研(yan)究(jiu)的(de)(de)(de)(de)(de)復(fu)(fu)雜面(mian)(mian)(mian)(mian)(mian)(mian)(mian)，之(zhi)間的(de)(de)(de)(de)(de)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)和(he)密(mi)封磨(mo)(mo)(mo)(mo)(mo)料磨(mo)(mo)(mo)(mo)(mo)具研(yan)究(jiu)相對運(yun)動(dong)(dong)時，密(mi)封圈表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)，磨(mo)(mo)(mo)(mo)(mo)料磨(mo)(mo)(mo)(mo)(mo)具研(yan)究(jiu)部分和(he)密(mi)封面(mian)(mian)(mian)(mian)(mian)(mian)(mian)之(zhi)間的(de)(de)(de)(de)(de)滑動(dong)(dong)或滾動(dong)(dong)，切斷密(mi)封圈上(shang)薄(bo)薄(bo)的(de)(de)(de)(de)(de)一層(ceng)金屬(shu)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)。密(mi)封凸峰(feng)部分的(de)(de)(de)(de)(de)圈，表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)研(yan)磨(mo)(mo)(mo)(mo)(mo)，然后逐(zhu)漸(jian)達到所要求的(de)(de)(de)(de)(de)幾何形(xing)狀。不僅是金屬(shu)磨(mo)(mo)(mo)(mo)(mo)料的(de)(de)(de)(de)(de)研(yan)磨(mo)(mo)(mo)(mo)(mo)加工(gong)，以及化(hua)(hua)學作用(yong)。研(yan)磨(mo)(mo)(mo)(mo)(mo)油可使加工(gong)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)形(xing)成的(de)(de)(de)(de)(de)氧(yang)化(hua)(hua)膜(mo)，從而加快(kuai)研(yan)磨(mo)(mo)(mo)(mo)(mo)過程。地面(mian)(mian)(mian)(mian)(mian)(mian)(mian)運(yun)動(dong)(dong)相對運(yun)動(dong)(dong)的(de)(de)(de)(de)(de)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)和(he)密(mi)封圈密(mi)封圈的(de)(de)(de)(de)(de)研(yan)究(jiu)，對每(mei)個點(dian)的(de)(de)(de)(de)(de)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)上(shang)的(de)(de)(de)(de)(de)道(dao)路和(he)相對滑動(dong)(dong)的(de)(de)(de)(de)(de)研(yan)究(jiu)應該是一樣的(de)(de)(de)(de)(de)。和(he)相對運(yun)動(dong)(dong)方向(xiang)(xiang)改變(bian)。改變(bian)密(mi)封環內(nei)的(de)(de)(de)(de)(de)每(mei)個粒(li)子的(de)(de)(de)(de)(de)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)上(shang)運(yun)動(dong)(dong)的(de)(de)(de)(de)(de)方向(xiang)(xiang)不會重復(fu)(fu)他們的(de)(de)(de)(de)(de)軌(gui)跡，以避(bi)免(mian)磨(mo)(mo)(mo)(mo)(mo)損明顯增加了密(mi)封環的(de)(de)(de)(de)(de)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)粗糙度。此外(wai)，運(yun)動(dong)(dong)方向(xiang)(xiang)的(de)(de)(de)(de)(de)改變(bian)不能使磨(mo)(mo)(mo)(mo)(mo)粒(li)分布比較均勻，且(qie)均勻切斷金屬(shu)密(mi)封環的(de)(de)(de)(de)(de)表面(mian)(mian)(mian)(mian)(mian)(mian)(mian)。

　　天寧機械密封研(yan)(yan)磨(mo)(mo)(mo)(mo)是利用(yong)(yong)涂敷或者壓嵌(qian)游離磨(mo)(mo)(mo)(mo)粒(li)(li)與(yu)研(yan)(yan)磨(mo)(mo)(mo)(mo)劑(ji)的(de)(de)(de)(de)混(hun)合物(wu)，在(zai)一(yi)定剛(gang)性(xing)的(de)(de)(de)(de)軟(ruan)質研(yan)(yan)具(ju)上(shang)，通過研(yan)(yan)具(ju)與(yu)工(gong)(gong)(gong)(gong)件向磨(mo)(mo)(mo)(mo)料(liao)施加(jia)(jia)一(yi)定壓力，磨(mo)(mo)(mo)(mo)料(liao)滾動與(yu)滑(hua)動，從被(bei)(bei)研(yan)(yan)磨(mo)(mo)(mo)(mo)工(gong)(gong)(gong)(gong)件上(shang)去除極薄的(de)(de)(de)(de)余量(liang)，以提高工(gong)(gong)(gong)(gong)件的(de)(de)(de)(de)精度和降(jiang)低表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)粗糙度值得加(jia)(jia)工(gong)(gong)(gong)(gong)方法(fa)。按(an)研(yan)(yan)磨(mo)(mo)(mo)(mo)時有無研(yan)(yan)磨(mo)(mo)(mo)(mo)液(ye)可分為干研(yan)(yan)與(yu)濕(shi)研(yan)(yan)。研(yan)(yan)磨(mo)(mo)(mo)(mo)過程(cheng)中(zhong)，在(zai)研(yan)(yan)磨(mo)(mo)(mo)(mo)壓力下(xia)，眾(zhong)多的(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)料(liao)微粒(li)(li)進(jin)行微量(liang)切(qie)削。對工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)進(jin)行擠壓、刻劃、滑(hua)擦(ca)(ca)；在(zai)研(yan)(yan)具(ju)運(yun)動中(zhong)當研(yan)(yan)具(ju)壓嵌(qian)的(de)(de)(de)(de)磨(mo)(mo)(mo)(mo)粒(li)(li)脫落后及液(ye)中(zhong)磨(mo)(mo)(mo)(mo)粒(li)(li)相對工(gong)(gong)(gong)(gong)件發(fa)生滾動。研(yan)(yan)磨(mo)(mo)(mo)(mo)過程(cheng)中(zhong)，在(zai)研(yan)(yan)磨(mo)(mo)(mo)(mo)壓力的(de)(de)(de)(de)作用(yong)(yong)下(xia)，眾(zhong)多磨(mo)(mo)(mo)(mo)粒(li)(li)進(jin)行微量(liang)切(qie)削，同(tong)時被(bei)(bei)研(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)發(fa)生微小起伏的(de)(de)(de)(de)塑性(xing)變(bian)形，并且被(bei)(bei)加(jia)(jia)入的(de)(de)(de)(de)諸(zhu)如硬脂酸(suan)、油酸(suan)、脂肪(fang)酸(suan)等(deng)活性(xing)物(wu)質與(yu)被(bei)(bei)研(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)起化學作用(yong)(yong)。隨著研(yan)(yan)磨(mo)(mo)(mo)(mo)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)進(jin)行，磨(mo)(mo)(mo)(mo)具(ju)與(yu)工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)間(jian)更趨(qu)貼(tie)近(jin)，其(qi)間(jian)充滿了(le)微屑(xie)與(yu)破(po)碎磨(mo)(mo)(mo)(mo)料(liao)的(de)(de)(de)(de)碎渣，堵(du)塞(sai)了(le)研(yan)(yan)具(ju)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)，對工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)起滑(hua)擦(ca)(ca)作用(yong)(yong)。所以，研(yan)(yan)磨(mo)(mo)(mo)(mo)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)(de)實(shi)質是磨(mo)(mo)(mo)(mo)粒(li)(li)的(de)(de)(de)(de)微量(liang)切(qie)削、研(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)微小起伏的(de)(de)(de)(de)塑性(xing)流動、表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)活性(xing)物(wu)質的(de)(de)(de)(de)化學作用(yong)(yong)及研(yan)(yan)具(ju)堵(du)塞(sai)物(wu)與(yu)工(gong)(gong)(gong)(gong)件表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)滑(hua)擦(ca)(ca)作用(yong)(yong)的(de)(de)(de)(de)綜(zong)合結(jie)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天寧機械密封將熱(re)量(liang)傳給軸(zhou)(zhou)承，使軸(zhou)(zhou)承溫度升高。為了控(kong)制(zhi)傳熱(re)，所(suo)以密(mi)封的水也(ye)起(qi)到冷卻作用。

　　天寧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天寧機械密封低(di)壓(ya)側(大氣)將清水(shui)、蒸汽等冷(leng)卻流體直接引(yin)入密封(feng)(feng)(feng)端泄(xie)露處(chu)的一種冷(leng)卻方式，也稱急冷(leng)，急冷(leng)不僅冷(leng)卻*，還能將密封(feng)(feng)(feng)端面周圍的雜質及泄(xie)露液(ye)帶走，急冷(leng)液(ye)其壓(ya)力比密封(feng)(feng)(feng)介(jie)質壓(ya)力低(di)。急冷(leng)液(ye)應盡量(liang)采用軟水(shui)，以防(fang)止水(shui)垢產生破壞密封(feng)(feng)(feng)端面。當密封(feng)(feng)(feng)流體為易凝固、易結(jie)晶(jing)時，可用蒸汽、溶劑等防(fang)止流體凝結(jie)。
