麗江研磨和冷卻對密封面都非常重要

  在研磨過程中,閥門制造的密封面是一個常用的整理方法,可以使麗江機械密封摩(mo)擦端面(mian)(mian)尺(chi)寸精(jing)度提高(gao),閥門(men)的密(mi)封面(mian)(mian),幾何粗糙(cao)(cao)度和表(biao)面(mian)(mian)粗糙(cao)(cao)度,但不(bu)能提高(gao)密(mi)封表(biao)面(mian)(mian)的相互位置(zhi)精(jing)度。


  麗江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,隨著對麗江機械密封研(yan)(yan)究(jiu)的(de)(de)復雜面(mian)(mian)(mian)(mian),之間(jian)(jian)的(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)和密封(feng)(feng)(feng)(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)究(jiu)相(xiang)對運(yun)動(dong)(dong)(dong)時,密封(feng)(feng)(feng)(feng)圈表(biao)(biao)(biao)面(mian)(mian)(mian)(mian),磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)(yan)究(jiu)部(bu)分(fen)和密封(feng)(feng)(feng)(feng)面(mian)(mian)(mian)(mian)之間(jian)(jian)的(de)(de)滑動(dong)(dong)(dong)或滾動(dong)(dong)(dong),切斷密封(feng)(feng)(feng)(feng)圈上薄薄的(de)(de)一層金(jin)屬(shu)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)。密封(feng)(feng)(feng)(feng)凸峰部(bu)分(fen)的(de)(de)圈,表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)研(yan)(yan)磨(mo)(mo)(mo),然后逐漸達(da)到所要求(qiu)的(de)(de)幾何形(xing)狀。不(bu)僅是(shi)金(jin)屬(shu)磨(mo)(mo)(mo)料的(de)(de)研(yan)(yan)磨(mo)(mo)(mo)加(jia)工(gong),以及化學作用。研(yan)(yan)磨(mo)(mo)(mo)油可使加(jia)工(gong)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)形(xing)成的(de)(de)氧化膜,從而(er)加(jia)快研(yan)(yan)磨(mo)(mo)(mo)過(guo)程(cheng)。地(di)面(mian)(mian)(mian)(mian)運(yun)動(dong)(dong)(dong)相(xiang)對運(yun)動(dong)(dong)(dong)的(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)和密封(feng)(feng)(feng)(feng)圈密封(feng)(feng)(feng)(feng)圈的(de)(de)研(yan)(yan)究(jiu),對每個點的(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)上的(de)(de)道路和相(xiang)對滑動(dong)(dong)(dong)的(de)(de)研(yan)(yan)究(jiu)應該是(shi)一樣的(de)(de)。和相(xiang)對運(yun)動(dong)(dong)(dong)方(fang)(fang)向改變。改變密封(feng)(feng)(feng)(feng)環內(nei)的(de)(de)每個粒子的(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)上運(yun)動(dong)(dong)(dong)的(de)(de)方(fang)(fang)向不(bu)會重復他(ta)們的(de)(de)軌跡,以避免磨(mo)(mo)(mo)損明顯增加(jia)了(le)密封(feng)(feng)(feng)(feng)環的(de)(de)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)粗糙度。此外,運(yun)動(dong)(dong)(dong)方(fang)(fang)向的(de)(de)改變不(bu)能使磨(mo)(mo)(mo)粒分(fen)布比較均勻,且均勻切斷金(jin)屬(shu)密封(feng)(feng)(feng)(feng)環的(de)(de)表(biao)(biao)(biao)面(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麗江機械密封將熱量傳給軸承,使軸承溫度升高。為了控制傳熱,所(suo)以密(mi)封(feng)的水(shui)也(ye)起(qi)到(dao)冷卻作用。


  麗江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麗江機械密封低壓側(大(da)氣(qi))將清水、蒸汽(qi)等(deng)冷(leng)(leng)卻流(liu)體(ti)直接(jie)引(yin)入密封(feng)(feng)端泄(xie)露(lu)處的(de)(de)一種冷(leng)(leng)卻方式,也稱急冷(leng)(leng),急冷(leng)(leng)不僅冷(leng)(leng)卻*,還(huan)能將密封(feng)(feng)端面周圍(wei)的(de)(de)雜質及泄(xie)露(lu)液帶走,急冷(leng)(leng)液其壓力比密封(feng)(feng)介質壓力低。急冷(leng)(leng)液應盡(jin)量采用軟水,以防(fang)止水垢產(chan)生(sheng)破壞密封(feng)(feng)端面。當密封(feng)(feng)流(liu)體(ti)為易凝固(gu)、易結(jie)(jie)晶時,可(ke)用蒸汽(qi)、溶劑等(deng)防(fang)止流(liu)體(ti)凝結(jie)(jie)。
