霍爾果斯機械密封的這三個功能一定要了解
機械密封包括壓力控制、溫度控制、流體替(ti)換(堵塞)和(he)雜質(zhi)去除系(xi)(xi)統。在機械密封系(xi)(xi)統中,上述(shu)系(xi)(xi)統并不同時包括在內。密封系(xi)(xi)統的選擇主要取決于主密封件的應用范圍(wei)。例如(ru),如(ru)...

機械密(mi)封是靠(kao)彈性元件(jian)(繃簧(huang)、波紋(wen)管等) 和密(mi)封液體壓力在相對運動的動環和靜環的接觸面(mian)(端(duan)面(mian))上發作一恰(qia)當的壓緊(jin)力(比(bi)壓)使(shi)兩個亮光、 平直的端(duan)面(mian)緊(jin)密(mi)貼合;端(duan)面(mian)間...
機械密(mi)封(feng)(feng)是(shi)一種依(yi)靠(kao)彈(dan)性元件對動(dong)、靜環(huan)端(duan)面密(mi)封(feng)(feng)副(fu)的預緊(jin)和介質壓力(li)與彈(dan)性元件壓力(li)的壓緊(jin)而達(da)到密(mi)封(feng)(feng)的軸(zhou)向端(duan)面密(mi)封(feng)(feng)裝置。動(dong)環(huan)和靜環(huan)的端(duan)面組成一對摩(mo)擦副(fu),動(dong)環(huan)靠(kao)密(mi)封(feng)(feng)室中液...
熱水(shui)泵(beng)集式機械(xie)密(mi)封是指安裝(zhuang)運(yun)行在泵(beng)類(lei)設備(bei)中起(qi)動態密(mi)封作用(yong)的裝(zhuang)置,避免水(shui)泵(beng)蝸殼中的流體(ti)介質通過泵(beng)軸(zhou)流出。由(you)于水(shui)泵(beng)多為輸(shu)送流體(ti)介質,具(ju)有水(shui)平(ping)安裝(zhuang)、高(gao)轉(zhuan)速(su)、高(gao)壓力(li)、帶(dai)...
反壓(ya)狀(zhuang)態(tai)是(shi)不(bu)良(liang)的(de)工作狀(zhuang)態(tai),介質中的(de)顆粒(li)、雜質很容易進入密封面(mian),使密封失效(xiao)。磨軸(zhou)的(de)主要(yao)件為(wei)橡膠波紋管,且由于(yu)上端密封面(mian)處于(yu)不(bu)良(liang)潤滑狀(zhuang)態(tai),動靜環之間的(de)摩(mo)擦(ca)力矩大(da)于(yu)橡...
