貢嘎機械密封的這三個功能一定要了解
機(ji)械密(mi)(mi)封(feng)包括壓力(li)控制、溫度控制、流(liu)體替(ti)換(堵塞)和雜質去除系統。在(zai)機(ji)械密(mi)(mi)封(feng)系統中,上(shang)述(shu)系統并不同時包括在(zai)內。密(mi)(mi)封(feng)系統的(de)選擇主要取決(jue)于(yu)主密(mi)(mi)封(feng)件的(de)應用范圍。例如,如...

雙端面小(xiao)彈(dan)簧平衡型密(mi)(mi)封(feng)所用摩擦副(fu)材料(liao)由動(dong)環和靜環所組成的摩擦副(fu)是機械(xie)密(mi)(mi)封(feng)重要(yao)的零件,從理論上講,為了(le)減(jian)少機械(xie)密(mi)(mi)封(feng)的磨損量,應(ying)該(gai)在合理的動(dong)力流體潤滑條件下工(gong)作(zuo)運轉...
我們(men)使(shi)用(yong)泵(beng)過程(cheng)中總會(hui)遇到(dao)(dao)密封膠圈損壞(huai)的(de)(de)情況(kuang),一旦損壞(huai)就要進行更換,作為一個工(gong)程(cheng)技術人員首(shou)先要分辨自己(ji)的(de)(de)泵(beng)到(dao)(dao)底是(shi)哪種型號,才(cai)能(neng)購買到(dao)(dao)相應口徑的(de)(de)機械密封,由于在(zai)市場...
在(zai)使用過(guo)程中,大多數(shu)機械密(mi)(mi)封都屬于(yu)接觸式密(mi)(mi)封,其(qi)機理是靠(kao)動(dong)密(mi)(mi)封環(huan)與(yu)靜(jing)密(mi)(mi)封環(huan)的接觸端(duan)面在(zai)密(mi)(mi)封流體壓(ya)力和彈(dan)性元(yuan)件壓(ya)緊力的作用下緊密(mi)(mi)貼合,并相對滑動(dong)而達到(dao)密(mi)(mi)封。工作時(shi)...

由于有氣(qi)(qi)囊(nang)的(de)存在(zai),氮(dan)氣(qi)(qi)與隔(ge)離(li)(li)液(ye)(ye)(ye)完全不(bu)接觸,避免了加壓(ya)(ya)氣(qi)(qi)體被隔(ge)離(li)(li)液(ye)(ye)(ye)吸收,使填料改集式(shi)密(mi)封可以用于液(ye)(ye)(ye)力透平等高壓(ya)(ya)操作工況(kuang),但是由于隔(ge)離(li)(li)液(ye)(ye)(ye)是在(zai)換熱器的(de)盤管(guan)中流動(dong),因此...
