在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使額敏機械密封摩擦端面尺寸精度提(ti)高，閥門的(de)密(mi)封面，幾(ji)何粗糙度和表(biao)面粗糙度，但不能提(ti)高密(mi)封表(biao)面的(de)相(xiang)互(hu)位置精度。

　　額敏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，隨著對額敏機械密封研(yan)究(jiu)(jiu)的(de)(de)(de)復(fu)雜面(mian)(mian)(mian)，之間的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)和(he)密(mi)(mi)(mi)封(feng)(feng)磨料(liao)(liao)磨具研(yan)究(jiu)(jiu)相對(dui)(dui)運動(dong)時，密(mi)(mi)(mi)封(feng)(feng)圈(quan)表(biao)(biao)(biao)面(mian)(mian)(mian)，磨料(liao)(liao)磨具研(yan)究(jiu)(jiu)部分和(he)密(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)(mian)之間的(de)(de)(de)滑動(dong)或滾(gun)動(dong)，切(qie)斷(duan)密(mi)(mi)(mi)封(feng)(feng)圈(quan)上薄(bo)薄(bo)的(de)(de)(de)一層金屬(shu)表(biao)(biao)(biao)面(mian)(mian)(mian)。密(mi)(mi)(mi)封(feng)(feng)凸峰部分的(de)(de)(de)圈(quan)，表(biao)(biao)(biao)面(mian)(mian)(mian)研(yan)磨，然后(hou)逐漸達(da)到(dao)所(suo)要求的(de)(de)(de)幾何形(xing)狀。不僅是金屬(shu)磨料(liao)(liao)的(de)(de)(de)研(yan)磨加(jia)工，以及化(hua)學作用。研(yan)磨油可(ke)使加(jia)工表(biao)(biao)(biao)面(mian)(mian)(mian)形(xing)成的(de)(de)(de)氧化(hua)膜(mo)，從而加(jia)快研(yan)磨過程。地面(mian)(mian)(mian)運動(dong)相對(dui)(dui)運動(dong)的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)和(he)密(mi)(mi)(mi)封(feng)(feng)圈(quan)密(mi)(mi)(mi)封(feng)(feng)圈(quan)的(de)(de)(de)研(yan)究(jiu)(jiu)，對(dui)(dui)每個點的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)上的(de)(de)(de)道路和(he)相對(dui)(dui)滑動(dong)的(de)(de)(de)研(yan)究(jiu)(jiu)應該是一樣的(de)(de)(de)。和(he)相對(dui)(dui)運動(dong)方(fang)向改變(bian)。改變(bian)密(mi)(mi)(mi)封(feng)(feng)環內(nei)的(de)(de)(de)每個粒(li)子的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)上運動(dong)的(de)(de)(de)方(fang)向不會重復(fu)他(ta)們的(de)(de)(de)軌跡，以避免磨損明顯(xian)增(zeng)加(jia)了密(mi)(mi)(mi)封(feng)(feng)環的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)粗糙度。此(ci)外，運動(dong)方(fang)向的(de)(de)(de)改變(bian)不能使磨粒(li)分布比較均勻(yun)，且均勻(yun)切(qie)斷(duan)金屬(shu)密(mi)(mi)(mi)封(feng)(feng)環的(de)(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)。

　　額敏機械密封研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)是利用(yong)涂敷(fu)或者壓(ya)嵌游離磨(mo)(mo)(mo)(mo)粒與(yu)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)劑的(de)(de)(de)混合物(wu)，在(zai)一定剛(gang)性(xing)的(de)(de)(de)軟(ruan)質(zhi)研(yan)(yan)(yan)具(ju)(ju)上，通過研(yan)(yan)(yan)具(ju)(ju)與(yu)工(gong)(gong)(gong)(gong)件(jian)向磨(mo)(mo)(mo)(mo)料施加一定壓(ya)力，磨(mo)(mo)(mo)(mo)料滾(gun)動(dong)與(yu)滑動(dong)，從被研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)工(gong)(gong)(gong)(gong)件(jian)上去除(chu)極薄(bo)的(de)(de)(de)余量，以提高工(gong)(gong)(gong)(gong)件(jian)的(de)(de)(de)精(jing)度和(he)降(jiang)低(di)表(biao)面(mian)(mian)(mian)(mian)粗糙度值得加工(gong)(gong)(gong)(gong)方法。按(an)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)時有無研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)液可分為干研(yan)(yan)(yan)與(yu)濕研(yan)(yan)(yan)。研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過程中(zhong)，在(zai)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)力下(xia)(xia)，眾多(duo)的(de)(de)(de)磨(mo)(mo)(mo)(mo)料微(wei)粒進(jin)(jin)(jin)行微(wei)量切削(xue)。對工(gong)(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)進(jin)(jin)(jin)行擠(ji)壓(ya)、刻(ke)劃、滑擦(ca)；在(zai)研(yan)(yan)(yan)具(ju)(ju)運動(dong)中(zhong)當研(yan)(yan)(yan)具(ju)(ju)壓(ya)嵌的(de)(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)(gong)(gong)(gong)件(jian)發(fa)生滾(gun)動(dong)。研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過程中(zhong)，在(zai)研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)力的(de)(de)(de)作(zuo)(zuo)(zuo)用(yong)下(xia)(xia)，眾多(duo)磨(mo)(mo)(mo)(mo)粒進(jin)(jin)(jin)行微(wei)量切削(xue)，同時被研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)(mian)發(fa)生微(wei)小(xiao)起伏(fu)的(de)(de)(de)塑性(xing)變(bian)形，并(bing)且被加入的(de)(de)(de)諸如硬脂酸、油酸、脂肪(fang)酸等活性(xing)物(wu)質(zhi)與(yu)被研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)(mian)起化學(xue)作(zuo)(zuo)(zuo)用(yong)。隨著研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加工(gong)(gong)(gong)(gong)的(de)(de)(de)進(jin)(jin)(jin)行，磨(mo)(mo)(mo)(mo)具(ju)(ju)與(yu)工(gong)(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)間更趨貼近，其間充滿了(le)微(wei)屑與(yu)破(po)碎磨(mo)(mo)(mo)(mo)料的(de)(de)(de)碎渣(zha)，堵塞了(le)研(yan)(yan)(yan)具(ju)(ju)表(biao)面(mian)(mian)(mian)(mian)，對工(gong)(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)起滑擦(ca)作(zuo)(zuo)(zuo)用(yong)。所以，研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加工(gong)(gong)(gong)(gong)的(de)(de)(de)實質(zhi)是磨(mo)(mo)(mo)(mo)粒的(de)(de)(de)微(wei)量切削(xue)、研(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)(mian)微(wei)小(xiao)起伏(fu)的(de)(de)(de)塑性(xing)流動(dong)、表(biao)面(mian)(mian)(mian)(mian)活性(xing)物(wu)質(zhi)的(de)(de)(de)化學(xue)作(zuo)(zuo)(zuo)用(yong)及研(yan)(yan)(yan)具(ju)(ju)堵塞物(wu)與(yu)工(gong)(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)滑擦(ca)作(zuo)(zuo)(zuo)用(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額敏機械密封將(jiang)熱量(liang)傳給軸承，使(shi)軸承溫度升高(gao)。為了控(kong)制傳熱，所以密封的水(shui)也起到冷卻作(zuo)用(yong)。

　　額敏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額敏機械密封低壓(ya)側(大氣(qi))將(jiang)(jiang)清水、蒸汽等(deng)(deng)冷(leng)(leng)卻(que)流體(ti)(ti)直接引(yin)入密封端泄露(lu)處的一種冷(leng)(leng)卻(que)方(fang)式，也稱急冷(leng)(leng)，急冷(leng)(leng)不僅冷(leng)(leng)卻(que)*，還能將(jiang)(jiang)密封端面周圍的雜(za)質及泄露(lu)液(ye)帶(dai)走，急冷(leng)(leng)液(ye)其壓(ya)力比密封介(jie)質壓(ya)力低。急冷(leng)(leng)液(ye)應(ying)盡量采用(yong)軟水，以防止水垢產(chan)生破壞密封端面。當密封流體(ti)(ti)為易凝(ning)固(gu)、易結(jie)晶(jing)時，可用(yong)蒸汽、溶(rong)劑等(deng)(deng)防止流體(ti)(ti)凝(ning)結(jie)。
