機械(xie)密封包括壓力控制、溫度(du)控制、流(liu)體(ti)替(ti)換(堵塞)和雜質(zhi)去(qu)除系(xi)(xi)統(tong)(tong)。在(zai)機械(xie)密封系(xi)(xi)統(tong)(tong)中，上述系(xi)(xi)統(tong)(tong)并不(bu)同時包括在(zai)內。密封系(xi)(xi)統(tong)(tong)的選(xuan)擇(ze)主要(yao)取決于主密封件(jian)的應用(yong)范圍。例如(ru)，如(ru)...
機(ji)械(xie)(xie)密封利用機(ji)械(xie)(xie)方式(shi)傳(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)，機(ji)械(xie)(xie)傳(chuan)動(dong)(dong)(dong)在機(ji)械(xie)(xie)工(gong)程中應用非常廣泛(fan)，有(you)多種形式(shi)，主(zhu)要(yao)包括皮帶(dai)傳(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)動(dong)(dong)(dong)和螺旋(xuan)傳(chuan)動(dong)(dong)(dong)...
機械密封是靠彈性元件(繃(beng)簧、波紋管等) 和(he)密封液體壓(ya)(ya)力在相(xiang)對運動(dong)的動(dong)環和(he)靜(jing)環的接觸面(mian)(端(duan)面(mian))上發作一恰當的壓(ya)(ya)緊力(比壓(ya)(ya))使兩(liang)個亮光、 平直的端(duan)面(mian)緊密貼合；端(duan)面(mian)間...
機械密封(feng)是一種依靠彈性元(yuan)件對(dui)動、靜(jing)環(huan)端面密封(feng)副的(de)預緊和介質壓力(li)與(yu)彈性元(yuan)件壓力(li)的(de)壓緊而達到密封(feng)的(de)軸(zhou)向(xiang)端面密封(feng)裝置。動環(huan)和靜(jing)環(huan)的(de)端面組成一對(dui)摩(mo)擦(ca)副，動環(huan)靠密封(feng)室中(zhong)液(ye)...
熱水泵集式機械密封(feng)是指(zhi)安裝運(yun)行在泵類設(she)備中(zhong)起動態密封(feng)作用(yong)的裝置，避免水泵蝸殼中(zhong)的流(liu)體介(jie)質通(tong)過泵軸流(liu)出(chu)。由(you)于水泵多為輸(shu)送流(liu)體介(jie)質，具有(you)水平(ping)安裝、高轉(zhuan)速、高壓(ya)力、帶(dai)...
反(fan)壓狀態(tai)是不良(liang)的(de)工(gong)作(zuo)狀態(tai)，介質(zhi)中的(de)顆粒、雜質(zhi)很(hen)容(rong)易(yi)進(jin)入(ru)密封(feng)面，使密封(feng)失(shi)效。磨軸的(de)主要件為(wei)橡(xiang)膠波紋管，且(qie)由于上端(duan)密封(feng)面處于不良(liang)潤(run)滑狀態(tai)，動靜環(huan)之間(jian)的(de)摩擦(ca)力矩大(da)于橡(xiang)...
