機械(xie)密(mi)封(feng)(feng)包(bao)括壓力控制(zhi)、溫度控制(zhi)、流體(ti)替換(堵塞)和(he)雜質去(qu)除系(xi)統(tong)(tong)(tong)。在機械(xie)密(mi)封(feng)(feng)系(xi)統(tong)(tong)(tong)中(zhong)，上述系(xi)統(tong)(tong)(tong)并不同時包(bao)括在內。密(mi)封(feng)(feng)系(xi)統(tong)(tong)(tong)的選擇(ze)主要取決于主密(mi)封(feng)(feng)件的應用范圍。例如，如...
機(ji)(ji)械密封利用機(ji)(ji)械方(fang)式(shi)傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程中應用非常廣(guang)泛(fan)，有多(duo)種(zhong)形式(shi)，主要包(bao)括皮帶(dai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)動(dong)(dong)(dong)(dong)(dong)...
機械密(mi)封是靠彈性元件(繃簧、波紋管等) 和密(mi)封液(ye)體(ti)壓(ya)力在相(xiang)對運動的動環和靜環的接觸面(端面)上(shang)發作一恰(qia)當的壓(ya)緊力(比壓(ya))使兩個亮(liang)光、 平直的端面緊密(mi)貼合；端面間...
機械密封是一種(zhong)依靠彈性元件(jian)對動(dong)、靜環端(duan)面(mian)密封副的(de)(de)(de)(de)預緊和(he)介質(zhi)壓(ya)力(li)(li)與彈性元件(jian)壓(ya)力(li)(li)的(de)(de)(de)(de)壓(ya)緊而達到密封的(de)(de)(de)(de)軸向端(duan)面(mian)密封裝置。動(dong)環和(he)靜環的(de)(de)(de)(de)端(duan)面(mian)組(zu)成一對摩擦副，動(dong)環靠密封室中液(ye)...
熱水(shui)(shui)泵(beng)集式(shi)機械密封(feng)是指(zhi)安裝運行在泵(beng)類設備(bei)中(zhong)起動(dong)態密封(feng)作用的裝置，避免水(shui)(shui)泵(beng)蝸殼中(zhong)的流(liu)體介(jie)質(zhi)(zhi)通過泵(beng)軸流(liu)出。由(you)于水(shui)(shui)泵(beng)多為輸送流(liu)體介(jie)質(zhi)(zhi)，具(ju)有水(shui)(shui)平安裝、高轉速、高壓力、帶(dai)...
反壓狀(zhuang)(zhuang)態(tai)是不良的工作(zuo)狀(zhuang)(zhuang)態(tai)，介質中(zhong)的顆(ke)粒(li)、雜質很容易進入密封(feng)面，使密封(feng)失效。磨軸(zhou)的主(zhu)要件為橡(xiang)膠(jiao)波紋(wen)管，且由于(yu)上端密封(feng)面處于(yu)不良潤滑狀(zhuang)(zhuang)態(tai)，動靜(jing)環之(zhi)間(jian)的摩(mo)擦力矩大于(yu)橡(xiang)...
