機械密封是靠(kao)彈性元件(繃(beng)簧、波(bo)紋管(guan)等) 和密封液體壓力(li)在(zai)相(xiang)對運動的(de)動環和靜環的(de)接觸面(mian)(端(duan)面(mian))上發作一(yi)恰當的(de)壓緊(jin)力(li)(比壓)使兩(liang)個亮光、 平(ping)直的(de)端(duan)面(mian)緊(jin)密貼(tie)合；端(duan)面(mian)間...
機(ji)械密(mi)封(feng)(feng)(feng)是(shi)一種依靠(kao)彈性元(yuan)件對(dui)動、靜環端面密(mi)封(feng)(feng)(feng)副(fu)的(de)預緊和(he)介質壓力與(yu)彈性元(yuan)件壓力的(de)壓緊而達到密(mi)封(feng)(feng)(feng)的(de)軸向端面密(mi)封(feng)(feng)(feng)裝置。動環和(he)靜環的(de)端面組成一對(dui)摩擦(ca)副(fu)，動環靠(kao)密(mi)封(feng)(feng)(feng)室中液...
熱(re)水(shui)泵集式機(ji)械密封是(shi)指安(an)裝(zhuang)運行(xing)在泵類設備中起動態密封作(zuo)用的裝(zhuang)置(zhi)，避免水(shui)泵蝸殼中的流體介(jie)質通過泵軸流出。由于水(shui)泵多為輸送流體介(jie)質，具(ju)有水(shui)平安(an)裝(zhuang)、高轉速、高壓力、帶(dai)...
反壓狀態是不良(liang)的工作(zuo)狀態，介質中(zhong)的顆粒(li)、雜(za)質很容易進入密封(feng)面，使密封(feng)失效。磨軸的主要件為橡膠波紋管，且由于(yu)上端密封(feng)面處于(yu)不良(liang)潤滑狀態，動靜環之(zhi)間的摩擦(ca)力矩大于(yu)橡...
