英德機械密封的這三個功能一定要了解
機械密(mi)封包括壓力控制、溫度控制、流(liu)體替換(堵塞(sai))和(he)雜質去(qu)除系(xi)統(tong)(tong)。在機械密(mi)封系(xi)統(tong)(tong)中,上述系(xi)統(tong)(tong)并不同時包括在內。密(mi)封系(xi)統(tong)(tong)的(de)(de)選擇主(zhu)要取決于(yu)主(zhu)密(mi)封件的(de)(de)應用范(fan)圍。例如,如...

雙端(duan)面小彈(dan)簧平衡型密(mi)封(feng)所用摩(mo)擦副材料(liao)由動(dong)環(huan)和靜環(huan)所組成的摩(mo)擦副是機(ji)械密(mi)封(feng)重要的零件,從(cong)理(li)論上(shang)講,為了減少(shao)機(ji)械密(mi)封(feng)的磨損量(liang),應(ying)該在(zai)合理(li)的動(dong)力流體(ti)潤滑(hua)條件下(xia)工作運轉(zhuan)...
我們使用泵(beng)(beng)過程(cheng)中總會遇到(dao)(dao)密封(feng)膠圈(quan)損(sun)壞(huai)的情況,一旦損(sun)壞(huai)就(jiu)要(yao)進行更換,作為一個工程(cheng)技術人員首先要(yao)分(fen)辨(bian)自己(ji)的泵(beng)(beng)到(dao)(dao)底(di)是(shi)哪種型(xing)號(hao),才能(neng)購買(mai)到(dao)(dao)相應口徑(jing)的機械密封(feng),由于在(zai)市(shi)場...
在使用過程中,大(da)多數機械密(mi)封(feng)(feng)都(dou)屬于接(jie)觸式密(mi)封(feng)(feng),其機理是靠動(dong)密(mi)封(feng)(feng)環(huan)與靜密(mi)封(feng)(feng)環(huan)的接(jie)觸端面在密(mi)封(feng)(feng)流體壓力和彈性元件壓緊力的作用下(xia)緊密(mi)貼合,并相對滑動(dong)而達到密(mi)封(feng)(feng)。工作時...
機(ji)(ji)械密封利用(yong)機(ji)(ji)械方式(shi)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機(ji)(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)(ji)械工程中(zhong)應用(yong)非常廣泛,有(you)多(duo)種形式(shi),主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)...
由于(yu)(yu)有氣囊的存在(zai),氮氣與隔(ge)離(li)液完全不接觸,避免了(le)加壓氣體被隔(ge)離(li)液吸收,使填料改集式密封可以(yi)用于(yu)(yu)液力透平等(deng)高壓操作(zuo)工(gong)況,但是由于(yu)(yu)隔(ge)離(li)液是在(zai)換熱(re)器(qi)的盤管中流動,因此...
