機械密封是靠彈性元件(jian)(繃簧、波紋管等) 和密封液體壓力在相(xiang)對運動的(de)動環(huan)和靜環(huan)的(de)接(jie)觸(chu)面(端(duan)面)上(shang)發作一恰當的(de)壓緊力(比壓)使兩個亮光(guang)、 平直的(de)端(duan)面緊密貼合;端(duan)面間(jian)...
機械密(mi)封(feng)是一(yi)種依(yi)靠彈(dan)性元(yuan)件對(dui)(dui)動、靜環(huan)(huan)(huan)端面(mian)(mian)密(mi)封(feng)副的預緊(jin)和(he)介(jie)質壓力與彈(dan)性元(yuan)件壓力的壓緊(jin)而達到密(mi)封(feng)的軸向端面(mian)(mian)密(mi)封(feng)裝置。動環(huan)(huan)(huan)和(he)靜環(huan)(huan)(huan)的端面(mian)(mian)組成(cheng)一(yi)對(dui)(dui)摩擦副,動環(huan)(huan)(huan)靠密(mi)封(feng)室中(zhong)液...
熱水泵(beng)集式機械密(mi)封(feng)是(shi)指安(an)(an)裝(zhuang)(zhuang)(zhuang)運行在泵(beng)類(lei)設備中起動態密(mi)封(feng)作用的裝(zhuang)(zhuang)(zhuang)置,避(bi)免水泵(beng)蝸殼中的流(liu)體介(jie)質通(tong)過泵(beng)軸流(liu)出。由于水泵(beng)多為(wei)輸(shu)送流(liu)體介(jie)質,具(ju)有(you)水平安(an)(an)裝(zhuang)(zhuang)(zhuang)、高轉(zhuan)速(su)、高壓力(li)、帶(dai)...
反壓狀態(tai)是不良(liang)的(de)(de)工作(zuo)狀態(tai),介質中的(de)(de)顆(ke)粒、雜質很容易進入密(mi)封(feng)面(mian),使(shi)密(mi)封(feng)失效。磨軸的(de)(de)主(zhu)要件為橡膠波紋管,且由于(yu)上端密(mi)封(feng)面(mian)處(chu)于(yu)不良(liang)潤滑狀態(tai),動靜環之間的(de)(de)摩擦力矩大于(yu)橡...
