機(ji)械密(mi)(mi)(mi)封是靠彈(dan)性元件(jian)(繃簧(huang)、波紋管(guan)等) 和密(mi)(mi)(mi)封液體壓(ya)力(li)在相對運動的(de)動環和靜環的(de)接觸面(端面)上發作一恰當的(de)壓(ya)緊力(li)(比壓(ya))使兩個亮光(guang)、 平直的(de)端面緊密(mi)(mi)(mi)貼合；端面間...
機械(xie)密(mi)(mi)封(feng)(feng)(feng)是(shi)一種依靠(kao)彈性元件對動、靜環端面(mian)(mian)密(mi)(mi)封(feng)(feng)(feng)副的預(yu)緊和(he)(he)介質(zhi)壓力與彈性元件壓力的壓緊而(er)達(da)到密(mi)(mi)封(feng)(feng)(feng)的軸向端面(mian)(mian)密(mi)(mi)封(feng)(feng)(feng)裝置。動環和(he)(he)靜環的端面(mian)(mian)組成(cheng)一對摩擦副，動環靠(kao)密(mi)(mi)封(feng)(feng)(feng)室(shi)中液...
熱水(shui)泵(beng)(beng)集式機械密封(feng)是指安裝運行在泵(beng)(beng)類(lei)設備中起動態密封(feng)作用的裝置(zhi)，避免水(shui)泵(beng)(beng)蝸殼(ke)中的流(liu)體(ti)介(jie)質通(tong)過泵(beng)(beng)軸流(liu)出。由于(yu)水(shui)泵(beng)(beng)多為輸送(song)流(liu)體(ti)介(jie)質，具(ju)有水(shui)平安裝、高(gao)轉速(su)、高(gao)壓力(li)、帶...
反壓狀態是不良(liang)的(de)工作狀態，介質中的(de)顆(ke)粒、雜(za)質很容易進入密封面，使密封失效。磨軸的(de)主要件為橡膠(jiao)波紋管(guan)，且(qie)由于上(shang)端密封面處于不良(liang)潤滑(hua)狀態，動靜環之(zhi)間的(de)摩擦力矩大于橡...
