機械(xie)密封(feng)是(shi)靠彈性元(yuan)件(jian)(繃簧、波(bo)紋管等) 和密封(feng)液體(ti)壓力在(zai)相對運動的(de)動環和靜環的(de)接觸(chu)面(mian)(mian)(mian)(端(duan)(duan)面(mian)(mian)(mian))上發作(zuo)一恰當的(de)壓緊(jin)(jin)力(比(bi)壓)使(shi)兩個亮光、 平直的(de)端(duan)(duan)面(mian)(mian)(mian)緊(jin)(jin)密貼(tie)合(he)；端(duan)(duan)面(mian)(mian)(mian)間...
機械密(mi)(mi)封(feng)是一種依(yi)靠(kao)(kao)彈(dan)性元件對動、靜(jing)環(huan)端(duan)面(mian)密(mi)(mi)封(feng)副(fu)的(de)(de)預緊和(he)介質壓力與彈(dan)性元件壓力的(de)(de)壓緊而達到(dao)密(mi)(mi)封(feng)的(de)(de)軸向端(duan)面(mian)密(mi)(mi)封(feng)裝置(zhi)。動環(huan)和(he)靜(jing)環(huan)的(de)(de)端(duan)面(mian)組成一對摩擦(ca)副(fu)，動環(huan)靠(kao)(kao)密(mi)(mi)封(feng)室(shi)中液...
熱水(shui)(shui)泵(beng)(beng)集式機械密封(feng)是指安裝(zhuang)運行(xing)在泵(beng)(beng)類設備(bei)中起(qi)動(dong)態密封(feng)作用的裝(zhuang)置，避免水(shui)(shui)泵(beng)(beng)蝸殼中的流體(ti)介質(zhi)通(tong)過泵(beng)(beng)軸流出(chu)。由于(yu)水(shui)(shui)泵(beng)(beng)多為輸送流體(ti)介質(zhi)，具(ju)有水(shui)(shui)平安裝(zhuang)、高轉速、高壓力、帶...
反(fan)壓狀(zhuang)態是(shi)不良(liang)的工作狀(zhuang)態，介質(zhi)中(zhong)的顆(ke)粒、雜質(zhi)很容易進入密(mi)封面，使密(mi)封失效。磨軸的主(zhu)要(yao)件為(wei)橡(xiang)膠波紋管，且由于(yu)上端密(mi)封面處于(yu)不良(liang)潤滑狀(zhuang)態，動靜(jing)環之間(jian)的摩擦力矩大于(yu)橡(xiang)...
