察隅機械密封的這三個功能一定要了解
機械(xie)密(mi)(mi)封包(bao)括壓力控(kong)制(zhi)、溫度控(kong)制(zhi)、流體替換(huan)(堵塞)和(he)雜(za)質去除系統。在機械(xie)密(mi)(mi)封系統中，上述系統并不同時包(bao)括在內。密(mi)(mi)封系統的選擇(ze)主要取決于主密(mi)(mi)封件(jian)的應用范(fan)圍。例如，如...

機(ji)(ji)械密封利用(yong)(yong)機(ji)(ji)械方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機(ji)(ji)械工(gong)程(cheng)中應用(yong)(yong)非常廣(guang)泛，有多種形式，主(zhu)要包括皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機械密封是靠(kao)彈性元件(繃(beng)簧、波(bo)紋管等) 和密封液體壓力(li)在相對運動(dong)的(de)動(dong)環和靜環的(de)接觸面(端(duan)(duan)面)上發作一恰當的(de)壓緊力(li)(比(bi)壓)使兩(liang)個(ge)亮光、 平直的(de)端(duan)(duan)面緊密貼合(he)；端(duan)(duan)面間...
機(ji)械密(mi)封(feng)是(shi)一種依(yi)靠彈(dan)(dan)性元(yuan)件(jian)對動、靜環(huan)端(duan)面(mian)密(mi)封(feng)副(fu)的(de)預(yu)緊(jin)和介質壓力與(yu)彈(dan)(dan)性元(yuan)件(jian)壓力的(de)壓緊(jin)而達到密(mi)封(feng)的(de)軸(zhou)向(xiang)端(duan)面(mian)密(mi)封(feng)裝置。動環(huan)和靜環(huan)的(de)端(duan)面(mian)組(zu)成一對摩(mo)擦(ca)副(fu)，動環(huan)靠密(mi)封(feng)室中液...
熱水(shui)(shui)(shui)泵(beng)(beng)(beng)集式機械密封是指安裝(zhuang)運行在泵(beng)(beng)(beng)類(lei)設備中起動態密封作(zuo)用的裝(zhuang)置，避免水(shui)(shui)(shui)泵(beng)(beng)(beng)蝸(gua)殼中的流(liu)體介質(zhi)通過泵(beng)(beng)(beng)軸流(liu)出(chu)。由于水(shui)(shui)(shui)泵(beng)(beng)(beng)多為輸送流(liu)體介質(zhi)，具(ju)有水(shui)(shui)(shui)平安裝(zhuang)、高轉(zhuan)速、高壓(ya)力、帶...
反壓(ya)狀(zhuang)(zhuang)態是不良的工作(zuo)狀(zhuang)(zhuang)態，介(jie)質中的顆(ke)粒、雜質很容易進(jin)入(ru)密封(feng)面(mian)(mian)，使密封(feng)失效。磨軸的主要(yao)件為橡膠波紋管(guan)，且由(you)于上端密封(feng)面(mian)(mian)處(chu)于不良潤滑狀(zhuang)(zhuang)態，動靜環(huan)之間(jian)的摩(mo)擦力矩大于橡...
