雙端面小彈簧平衡型密(mi)封(feng)所(suo)用摩(mo)擦(ca)副材料由動(dong)環(huan)和靜環(huan)所(suo)組(zu)成(cheng)的(de)(de)摩(mo)擦(ca)副是機械密(mi)封(feng)重要的(de)(de)零件(jian),從理論上(shang)講,為了減(jian)少機械密(mi)封(feng)的(de)(de)磨(mo)損量,應該在合理的(de)(de)動(dong)力流體潤滑(hua)條件(jian)下工作運轉(zhuan)...
我(wo)們使用(yong)泵過程(cheng)(cheng)中總會遇(yu)到(dao)(dao)密封膠圈損(sun)壞的(de)情況(kuang),一旦損(sun)壞就要進行更換,作(zuo)為(wei)一個工程(cheng)(cheng)技(ji)術(shu)人員首先要分辨(bian)自己的(de)泵到(dao)(dao)底是哪種型號(hao),才能購買到(dao)(dao)相應口徑的(de)機(ji)械密封,由于在市場...
在(zai)使用(yong)過程(cheng)中,大多(duo)數(shu)機械密封(feng)(feng)都(dou)屬于接(jie)觸式密封(feng)(feng),其機理是靠動密封(feng)(feng)環與(yu)靜密封(feng)(feng)環的接(jie)觸端面在(zai)密封(feng)(feng)流體(ti)壓(ya)力和彈性元件(jian)壓(ya)緊力的作用(yong)下緊密貼合(he),并(bing)相對滑(hua)動而達(da)到(dao)密封(feng)(feng)。工(gong)作時(shi)...
機械(xie)密封利用機械(xie)方(fang)式(shi)傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)工程中應用非常(chang)廣泛,有多種(zhong)形式(shi),主(zhu)要包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
由(you)于(yu)有氣(qi)囊的存(cun)在,氮氣(qi)與隔離液(ye)(ye)完全(quan)不接(jie)觸,避(bi)免了加壓氣(qi)體被隔離液(ye)(ye)吸收,使填料(liao)改集式(shi)密封可以用于(yu)液(ye)(ye)力透平等高壓操作工況,但是由(you)于(yu)隔離液(ye)(ye)是在換熱器的盤管中流動,因此...
