蓬安機械密封的這三個功能一定要了解
機械(xie)密封包括壓力控(kong)制(zhi)、溫度控(kong)制(zhi)、流體(ti)替換(堵塞)和(he)雜質去除系(xi)統(tong)。在(zai)機械(xie)密封系(xi)統(tong)中,上述(shu)系(xi)統(tong)并不(bu)同時包括在(zai)內。密封系(xi)統(tong)的選(xuan)擇主要取決于主密封件的應(ying)用(yong)范圍。例如(ru),如(ru)...

雙端(duan)面小彈簧平衡型密(mi)封(feng)所用摩(mo)擦副材(cai)料由動環(huan)和靜環(huan)所組成的(de)摩(mo)擦副是機械密(mi)封(feng)重要的(de)零(ling)件,從理論上講,為(wei)了減少機械密(mi)封(feng)的(de)磨損(sun)量(liang),應該在合理的(de)動力(li)流體潤滑(hua)條件下工作運(yun)轉...
我(wo)們(men)使用(yong)泵(beng)過程(cheng)(cheng)中總(zong)會遇到密封膠圈(quan)損(sun)壞(huai)的(de)情況,一旦損(sun)壞(huai)就要進(jin)行更換,作為一個工程(cheng)(cheng)技術人員首先要分(fen)辨自己(ji)的(de)泵(beng)到底是哪(na)種型(xing)號,才能購買到相應(ying)口徑的(de)機(ji)械(xie)密封,由(you)于(yu)在市場...
在(zai)使用過程(cheng)中,大多數機(ji)械(xie)密(mi)封(feng)(feng)都(dou)屬(shu)于(yu)接(jie)觸式(shi)密(mi)封(feng)(feng),其(qi)機(ji)理(li)是靠動密(mi)封(feng)(feng)環與靜密(mi)封(feng)(feng)環的(de)接(jie)觸端面在(zai)密(mi)封(feng)(feng)流(liu)體壓力(li)和(he)彈性元件壓緊力(li)的(de)作用下緊密(mi)貼合,并相對滑動而(er)達到(dao)密(mi)封(feng)(feng)。工(gong)作時...
