機械(xie)密封是靠彈(dan)性元(yuan)件(繃簧、波紋管等) 和密封液(ye)體壓(ya)力在相(xiang)對(dui)運(yun)動的(de)動環和靜(jing)環的(de)接觸面(mian)(端(duan)面(mian))上發作一恰當的(de)壓(ya)緊力(比壓(ya))使(shi)兩個亮光、 平(ping)直的(de)端(duan)面(mian)緊密貼合(he)；端(duan)面(mian)間...
機(ji)械密(mi)封(feng)是一種依(yi)靠(kao)彈(dan)性元件對(dui)動、靜環(huan)端(duan)面密(mi)封(feng)副的預緊(jin)(jin)和(he)介質壓力(li)(li)與彈(dan)性元件壓力(li)(li)的壓緊(jin)(jin)而(er)達(da)到密(mi)封(feng)的軸向端(duan)面密(mi)封(feng)裝置。動環(huan)和(he)靜環(huan)的端(duan)面組成一對(dui)摩(mo)擦副，動環(huan)靠(kao)密(mi)封(feng)室(shi)中(zhong)液...
熱水泵(beng)集式(shi)機械密(mi)封是指安(an)裝(zhuang)運行在泵(beng)類設備(bei)中起動態(tai)密(mi)封作用(yong)的(de)裝(zhuang)置，避免水泵(beng)蝸殼中的(de)流(liu)體介質(zhi)通(tong)過泵(beng)軸(zhou)流(liu)出。由于水泵(beng)多為輸送流(liu)體介質(zhi)，具有(you)水平(ping)安(an)裝(zhuang)、高(gao)轉速(su)、高(gao)壓力、帶...
反壓狀(zhuang)(zhuang)態(tai)是(shi)不良的(de)工作狀(zhuang)(zhuang)態(tai)，介質(zhi)中(zhong)的(de)顆(ke)粒、雜質(zhi)很容易進(jin)入密封(feng)(feng)面，使(shi)密封(feng)(feng)失效。磨軸的(de)主要件(jian)為橡膠波紋管，且(qie)由于上端密封(feng)(feng)面處于不良潤滑狀(zhuang)(zhuang)態(tai)，動靜環之(zhi)間(jian)的(de)摩擦力矩大(da)于橡...
