總口管理區機械密封的這三個功能一定要了解
機械密(mi)封(feng)包括(kuo)壓力控(kong)制、溫度控(kong)制、流體(ti)替換(堵塞(sai))和雜(za)質去除系(xi)統(tong)。在機械密(mi)封(feng)系(xi)統(tong)中,上述系(xi)統(tong)并不同時包括(kuo)在內(nei)。密(mi)封(feng)系(xi)統(tong)的選(xuan)擇主要(yao)取決于主密(mi)封(feng)件的應用范圍。例(li)如(ru),如(ru)...

雙端面小彈簧平(ping)衡型密封所用摩擦副(fu)材料由動環和靜(jing)環所組成的(de)摩擦副(fu)是機(ji)械密封重要的(de)零(ling)件(jian),從理論上講,為了(le)減少(shao)機(ji)械密封的(de)磨損量,應(ying)該在合理的(de)動力流體(ti)潤滑條(tiao)件(jian)下工(gong)作(zuo)運轉...
我們使(shi)用泵過程中總會遇到(dao)(dao)密封膠圈損壞(huai)(huai)的(de)情況,一旦損壞(huai)(huai)就要進行更換(huan),作為一個工程技術人(ren)員首先要分辨自己(ji)的(de)泵到(dao)(dao)底是(shi)哪種型號,才能購買到(dao)(dao)相應口徑的(de)機械(xie)密封,由于在市場(chang)...
在(zai)使用過程中,大多數機械密(mi)(mi)封(feng)(feng)都屬于接觸式密(mi)(mi)封(feng)(feng),其機理是靠動(dong)(dong)密(mi)(mi)封(feng)(feng)環與靜密(mi)(mi)封(feng)(feng)環的接觸端面在(zai)密(mi)(mi)封(feng)(feng)流體壓力和彈性元件壓緊力的作(zuo)用下緊密(mi)(mi)貼合(he),并相對滑動(dong)(dong)而達到(dao)密(mi)(mi)封(feng)(feng)。工(gong)作(zuo)時...
機械密封利用(yong)機械方(fang)式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong),機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機械工(gong)程中應用(yong)非常廣泛,有(you)多種形(xing)式,主要包括皮帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)...
由(you)于(yu)有氣(qi)(qi)囊的存在,氮氣(qi)(qi)與隔(ge)離液(ye)完全(quan)不接觸,避免了加(jia)壓(ya)氣(qi)(qi)體被隔(ge)離液(ye)吸(xi)收,使填料(liao)改集式密封可(ke)以用于(yu)液(ye)力(li)透平等高壓(ya)操(cao)作工況,但是由(you)于(yu)隔(ge)離液(ye)是在換熱器的盤(pan)管(guan)中流動,因此...
