在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使青松路街道機械密封摩擦端面尺寸精度(du)提(ti)高，閥門的(de)密(mi)封(feng)面，幾何粗(cu)糙度(du)和表(biao)面粗(cu)糙度(du)，但不能提(ti)高密(mi)封(feng)表(biao)面的(de)相互位置(zhi)精度(du)。

　　青松路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，隨著對青松路街道機械密封研(yan)究的(de)(de)(de)(de)(de)復雜面(mian)(mian)(mian)(mian)(mian)，之間的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)(mian)和(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)磨(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)具研(yan)究相對(dui)運動時，密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)表(biao)面(mian)(mian)(mian)(mian)(mian)，磨(mo)(mo)(mo)料(liao)磨(mo)(mo)(mo)具研(yan)究部分(fen)和(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)面(mian)(mian)(mian)(mian)(mian)之間的(de)(de)(de)(de)(de)滑動或(huo)滾動，切斷密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)上薄薄的(de)(de)(de)(de)(de)一層金(jin)屬(shu)表(biao)面(mian)(mian)(mian)(mian)(mian)。密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)凸峰(feng)部分(fen)的(de)(de)(de)(de)(de)圈(quan)(quan)，表(biao)面(mian)(mian)(mian)(mian)(mian)研(yan)磨(mo)(mo)(mo)，然后(hou)逐(zhu)漸達到所要求的(de)(de)(de)(de)(de)幾何(he)形狀。不僅是(shi)(shi)金(jin)屬(shu)磨(mo)(mo)(mo)料(liao)的(de)(de)(de)(de)(de)研(yan)磨(mo)(mo)(mo)加工，以及化(hua)學作用。研(yan)磨(mo)(mo)(mo)油可使加工表(biao)面(mian)(mian)(mian)(mian)(mian)形成的(de)(de)(de)(de)(de)氧化(hua)膜，從而(er)加快研(yan)磨(mo)(mo)(mo)過(guo)程。地面(mian)(mian)(mian)(mian)(mian)運動相對(dui)運動的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)(mian)和(he)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)圈(quan)(quan)的(de)(de)(de)(de)(de)研(yan)究，對(dui)每個點的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)(mian)上的(de)(de)(de)(de)(de)道路(lu)和(he)相對(dui)滑動的(de)(de)(de)(de)(de)研(yan)究應該是(shi)(shi)一樣的(de)(de)(de)(de)(de)。和(he)相對(dui)運動方向改(gai)變(bian)。改(gai)變(bian)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)內的(de)(de)(de)(de)(de)每個粒(li)子(zi)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)(mian)上運動的(de)(de)(de)(de)(de)方向不會重復他們(men)的(de)(de)(de)(de)(de)軌跡，以避免磨(mo)(mo)(mo)損明顯增加了(le)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)(mian)粗糙度。此外(wai)，運動方向的(de)(de)(de)(de)(de)改(gai)變(bian)不能(neng)使磨(mo)(mo)(mo)粒(li)分(fen)布比較(jiao)均(jun)勻，且均(jun)勻切斷金(jin)屬(shu)密(mi)(mi)(mi)(mi)封(feng)(feng)(feng)環(huan)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)(mian)(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青松路街道機械密封將熱(re)量傳(chuan)給(gei)軸承，使軸承溫度(du)升(sheng)高。為了控制傳(chuan)熱(re)，所以密封的水也(ye)起(qi)到冷卻(que)作(zuo)用(yong)。

　　青松路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青松路街道機械密封低壓側(大氣)將清水(shui)、蒸汽等(deng)冷卻流體直接(jie)引入密(mi)封端(duan)泄露(lu)處的(de)一種冷卻方(fang)式，也稱急冷，急冷不僅(jin)冷卻*，還能將密(mi)封端(duan)面周圍的(de)雜質(zhi)(zhi)及泄露(lu)液帶走，急冷液其壓力比(bi)密(mi)封介質(zhi)(zhi)壓力低。急冷液應盡量采用軟水(shui)，以防止(zhi)水(shui)垢產生破壞密(mi)封端(duan)面。當密(mi)封流體為(wei)易(yi)凝固(gu)、易(yi)結晶時(shi)，可用蒸汽、溶(rong)劑(ji)等(deng)防止(zhi)流體凝結。
