稱多機械密封的這三個功能一定要了解
機械密封包括(kuo)壓力控制、溫度(du)控制、流體(ti)替(ti)換(堵塞)和雜質去除系(xi)(xi)統(tong)(tong)。在機械密封系(xi)(xi)統(tong)(tong)中,上述(shu)系(xi)(xi)統(tong)(tong)并不同時包括(kuo)在內。密封系(xi)(xi)統(tong)(tong)的選擇主要取決(jue)于主密封件的應用范圍(wei)。例如,如...

機(ji)械密封利用機(ji)械方(fang)式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程中應用非常廣(guang)泛,有多種(zhong)形式,主要包(bao)括皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機械密封是靠彈性元件(繃簧、波紋管等) 和(he)密封液體壓(ya)(ya)力在相對運動的(de)動環(huan)和(he)靜環(huan)的(de)接觸面(端面)上發作一(yi)恰當(dang)的(de)壓(ya)(ya)緊力(比壓(ya)(ya))使兩(liang)個(ge)亮光、 平直(zhi)的(de)端面緊密貼合;端面間...
機械密(mi)封是一(yi)種依靠彈性元件對(dui)動、靜環端(duan)(duan)面密(mi)封副的(de)預緊和(he)介質(zhi)壓力(li)與彈性元件壓力(li)的(de)壓緊而達到密(mi)封的(de)軸向端(duan)(duan)面密(mi)封裝(zhuang)置。動環和(he)靜環的(de)端(duan)(duan)面組(zu)成一(yi)對(dui)摩擦副,動環靠密(mi)封室中液...
熱水泵(beng)集式(shi)機(ji)械密(mi)封是指安裝運行在泵(beng)類設備中起動態密(mi)封作用的裝置,避免水泵(beng)蝸殼中的流體介質通(tong)過泵(beng)軸流出。由于水泵(beng)多為輸送流體介質,具有水平安裝、高轉速、高壓力、帶...
反壓狀(zhuang)態是不良的工作狀(zhuang)態,介(jie)質中(zhong)的顆(ke)粒、雜質很容易進(jin)入密(mi)封(feng)(feng)面,使密(mi)封(feng)(feng)失效。磨軸(zhou)的主(zhu)要(yao)件為橡(xiang)膠波紋(wen)管(guan),且由(you)于(yu)上(shang)端密(mi)封(feng)(feng)面處于(yu)不良潤滑狀(zhuang)態,動靜環之間(jian)的摩擦力矩大于(yu)橡(xiang)...
