機械密封(feng)是靠彈性(xing)元件(jian)(繃簧、波紋管等) 和密封(feng)液體(ti)壓力在相對運動的(de)動環和靜環的(de)接觸面(mian)(端面(mian))上發作一恰當(dang)的(de)壓緊力(比壓)使兩個亮光、 平(ping)直的(de)端面(mian)緊密貼合；端面(mian)間...
機(ji)械(xie)密封(feng)是(shi)一種(zhong)依靠彈(dan)性元件對動、靜(jing)環(huan)(huan)端面(mian)密封(feng)副的(de)預緊(jin)和介質壓(ya)力與彈(dan)性元件壓(ya)力的(de)壓(ya)緊(jin)而達(da)到密封(feng)的(de)軸(zhou)向端面(mian)密封(feng)裝置(zhi)。動環(huan)(huan)和靜(jing)環(huan)(huan)的(de)端面(mian)組成一對摩擦副，動環(huan)(huan)靠密封(feng)室中液(ye)...
熱水(shui)泵集式(shi)機械密封是指安裝(zhuang)(zhuang)運行在泵類設備中起動態密封作用(yong)的裝(zhuang)(zhuang)置，避(bi)免水(shui)泵蝸殼中的流(liu)體(ti)介質通過(guo)泵軸流(liu)出。由于(yu)水(shui)泵多為輸送流(liu)體(ti)介質，具有(you)水(shui)平安裝(zhuang)(zhuang)、高轉速、高壓力、帶...
反壓(ya)狀(zhuang)態(tai)是不良的工作(zuo)狀(zhuang)態(tai)，介質中的顆粒(li)、雜(za)質很容易進入密(mi)封(feng)面，使密(mi)封(feng)失效。磨(mo)軸的主要件為橡膠波(bo)紋管(guan)，且(qie)由于上端(duan)密(mi)封(feng)面處于不良潤滑狀(zhuang)態(tai)，動靜環之間的摩擦力矩大于橡...
