在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使托喀依鄉機械密封摩擦端面(mian)(mian)尺寸(cun)精度(du)提(ti)高，閥門的密(mi)(mi)封(feng)面(mian)(mian)，幾何粗糙度(du)和表(biao)面(mian)(mian)粗糙度(du)，但不能提(ti)高密(mi)(mi)封(feng)表(biao)面(mian)(mian)的相互位置(zhi)精度(du)。

　　托喀依鄉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，隨著對托喀依鄉機械密封研(yan)(yan)究(jiu)(jiu)的(de)(de)(de)(de)(de)復雜面(mian)，之(zhi)(zhi)間的(de)(de)(de)(de)(de)表(biao)面(mian)和密(mi)(mi)(mi)封(feng)(feng)磨(mo)(mo)料(liao)(liao)磨(mo)(mo)具(ju)研(yan)(yan)究(jiu)(jiu)相(xiang)對(dui)運(yun)(yun)(yun)(yun)動(dong)(dong)(dong)時，密(mi)(mi)(mi)封(feng)(feng)圈表(biao)面(mian)，磨(mo)(mo)料(liao)(liao)磨(mo)(mo)具(ju)研(yan)(yan)究(jiu)(jiu)部分和密(mi)(mi)(mi)封(feng)(feng)面(mian)之(zhi)(zhi)間的(de)(de)(de)(de)(de)滑(hua)(hua)動(dong)(dong)(dong)或滾動(dong)(dong)(dong)，切斷密(mi)(mi)(mi)封(feng)(feng)圈上薄(bo)薄(bo)的(de)(de)(de)(de)(de)一層金(jin)屬(shu)表(biao)面(mian)。密(mi)(mi)(mi)封(feng)(feng)凸峰部分的(de)(de)(de)(de)(de)圈，表(biao)面(mian)研(yan)(yan)磨(mo)(mo)，然后逐漸達到所要求的(de)(de)(de)(de)(de)幾何形(xing)狀。不(bu)僅是金(jin)屬(shu)磨(mo)(mo)料(liao)(liao)的(de)(de)(de)(de)(de)研(yan)(yan)磨(mo)(mo)加工，以(yi)及化(hua)學(xue)作用。研(yan)(yan)磨(mo)(mo)油可使加工表(biao)面(mian)形(xing)成的(de)(de)(de)(de)(de)氧化(hua)膜(mo)，從而(er)加快研(yan)(yan)磨(mo)(mo)過程。地面(mian)運(yun)(yun)(yun)(yun)動(dong)(dong)(dong)相(xiang)對(dui)運(yun)(yun)(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)表(biao)面(mian)和密(mi)(mi)(mi)封(feng)(feng)圈密(mi)(mi)(mi)封(feng)(feng)圈的(de)(de)(de)(de)(de)研(yan)(yan)究(jiu)(jiu)，對(dui)每個點的(de)(de)(de)(de)(de)表(biao)面(mian)上的(de)(de)(de)(de)(de)道(dao)路和相(xiang)對(dui)滑(hua)(hua)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)研(yan)(yan)究(jiu)(jiu)應該是一樣的(de)(de)(de)(de)(de)。和相(xiang)對(dui)運(yun)(yun)(yun)(yun)動(dong)(dong)(dong)方向改變。改變密(mi)(mi)(mi)封(feng)(feng)環內的(de)(de)(de)(de)(de)每個粒(li)子的(de)(de)(de)(de)(de)表(biao)面(mian)上運(yun)(yun)(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)(de)(de)方向不(bu)會重復他們的(de)(de)(de)(de)(de)軌(gui)跡(ji)，以(yi)避免(mian)磨(mo)(mo)損(sun)明顯增加了密(mi)(mi)(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)表(biao)面(mian)粗糙度。此外，運(yun)(yun)(yun)(yun)動(dong)(dong)(dong)方向的(de)(de)(de)(de)(de)改變不(bu)能使磨(mo)(mo)粒(li)分布比較均勻(yun)，且(qie)均勻(yun)切斷金(jin)屬(shu)密(mi)(mi)(mi)封(feng)(feng)環的(de)(de)(de)(de)(de)表(biao)面(mian)。

　　托喀依鄉機械密封研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)是利用涂(tu)敷或(huo)者壓嵌游離磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)粒與(yu)(yu)(yu)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)劑的(de)(de)混合物(wu)，在(zai)一定剛性(xing)的(de)(de)軟質(zhi)研(yan)(yan)(yan)(yan)(yan)(yan)具(ju)(ju)上，通過研(yan)(yan)(yan)(yan)(yan)(yan)具(ju)(ju)與(yu)(yu)(yu)工(gong)(gong)(gong)件(jian)向(xiang)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)料(liao)施(shi)加(jia)一定壓力(li)，磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)料(liao)滾(gun)動(dong)與(yu)(yu)(yu)滑動(dong)，從被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)工(gong)(gong)(gong)件(jian)上去除(chu)極薄的(de)(de)余量，以提高(gao)工(gong)(gong)(gong)件(jian)的(de)(de)精度和降(jiang)低表(biao)面(mian)(mian)(mian)(mian)(mian)粗(cu)糙度值得加(jia)工(gong)(gong)(gong)方法。按研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)時有無(wu)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)液可分為干研(yan)(yan)(yan)(yan)(yan)(yan)與(yu)(yu)(yu)濕研(yan)(yan)(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)過程(cheng)中，在(zai)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)壓力(li)下，眾多(duo)的(de)(de)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)料(liao)微粒進(jin)行微量切削。對(dui)工(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)(mian)進(jin)行擠壓、刻劃、滑擦；在(zai)研(yan)(yan)(yan)(yan)(yan)(yan)具(ju)(ju)運動(dong)中當研(yan)(yan)(yan)(yan)(yan)(yan)具(ju)(ju)壓嵌的(de)(de)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)粒脫(tuo)落后及(ji)液中磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)粒相(xiang)對(dui)工(gong)(gong)(gong)件(jian)發(fa)生滾(gun)動(dong)。研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)過程(cheng)中，在(zai)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)壓力(li)的(de)(de)作(zuo)用下，眾多(duo)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)粒進(jin)行微量切削，同(tong)時被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)(mian)(mian)發(fa)生微小起伏的(de)(de)塑(su)性(xing)變形，并(bing)且被(bei)(bei)加(jia)入的(de)(de)諸如硬(ying)脂酸、油酸、脂肪酸等活性(xing)物(wu)質(zhi)與(yu)(yu)(yu)被(bei)(bei)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)(mian)(mian)起化學作(zuo)用。隨著(zhu)研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)加(jia)工(gong)(gong)(gong)的(de)(de)進(jin)行，磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)具(ju)(ju)與(yu)(yu)(yu)工(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)(mian)間更趨貼近，其間充(chong)滿(man)了微屑(xie)與(yu)(yu)(yu)破碎磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)料(liao)的(de)(de)碎渣(zha)，堵塞(sai)了研(yan)(yan)(yan)(yan)(yan)(yan)具(ju)(ju)表(biao)面(mian)(mian)(mian)(mian)(mian)，對(dui)工(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)(mian)起滑擦作(zuo)用。所以，研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)加(jia)工(gong)(gong)(gong)的(de)(de)實(shi)質(zhi)是磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)粒的(de)(de)微量切削、研(yan)(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)(mo)(mo)(mo)表(biao)面(mian)(mian)(mian)(mian)(mian)微小起伏的(de)(de)塑(su)性(xing)流動(dong)、表(biao)面(mian)(mian)(mian)(mian)(mian)活性(xing)物(wu)質(zhi)的(de)(de)化學作(zuo)用及(ji)研(yan)(yan)(yan)(yan)(yan)(yan)具(ju)(ju)堵塞(sai)物(wu)與(yu)(yu)(yu)工(gong)(gong)(gong)件(jian)表(biao)面(mian)(mian)(mian)(mian)(mian)滑擦作(zuo)用的(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托喀依鄉機械密封將熱量傳給軸(zhou)承，使軸(zhou)承溫度升高。為了控(kong)制傳熱，所以密(mi)封的水也起(qi)到(dao)冷卻作用。

　　托喀依鄉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托喀依鄉機械密封低壓(ya)(ya)側(ce)(大氣(qi))將清水(shui)(shui)、蒸汽等冷卻(que)流(liu)體直接(jie)引入密(mi)封(feng)端泄(xie)露處的一種冷卻(que)方式，也稱急(ji)冷，急(ji)冷不僅冷卻(que)*，還能(neng)將密(mi)封(feng)端面周圍(wei)的雜(za)質(zhi)及泄(xie)露液帶走，急(ji)冷液其壓(ya)(ya)力(li)比密(mi)封(feng)介質(zhi)壓(ya)(ya)力(li)低。急(ji)冷液應盡(jin)量(liang)采用軟水(shui)(shui)，以防(fang)止水(shui)(shui)垢產生(sheng)破(po)壞密(mi)封(feng)端面。當密(mi)封(feng)流(liu)體為易凝固、易結晶時，可用蒸汽、溶劑等防(fang)止流(liu)體凝結。
