鐵嶺機械密封的這三個功能一定要了解
機械密封(feng)(feng)包括(kuo)壓(ya)力控制、溫度控制、流體替換(堵塞)和雜質去除系(xi)統。在機械密封(feng)(feng)系(xi)統中,上述系(xi)統并不(bu)同時包括(kuo)在內。密封(feng)(feng)系(xi)統的選擇主(zhu)要取決(jue)于主(zhu)密封(feng)(feng)件的應用(yong)范圍。例如,如...

機(ji)(ji)械(xie)(xie)密封(feng)利用機(ji)(ji)械(xie)(xie)方(fang)式傳(chuan)遞動(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)的(de)傳(chuan)動(dong)(dong)(dong)(dong),機(ji)(ji)械(xie)(xie)傳(chuan)動(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)(xie)工(gong)程中應用非(fei)常廣泛,有多種形(xing)式,主要(yao)包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)動(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)動(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)動(dong)(dong)(dong)(dong)...
機械密(mi)(mi)封是靠(kao)彈性元件(jian)(繃簧、波紋(wen)管等) 和密(mi)(mi)封液體(ti)壓力在相對(dui)運動的動環和靜環的接觸面(mian)(端面(mian))上發作(zuo)一恰當的壓緊(jin)力(比壓)使(shi)兩個亮光、 平直的端面(mian)緊(jin)密(mi)(mi)貼合;端面(mian)間...
機械密(mi)封(feng)是一(yi)種依靠彈性元件對動、靜(jing)環端(duan)(duan)面密(mi)封(feng)副的(de)預緊和介質(zhi)壓(ya)(ya)(ya)力與彈性元件壓(ya)(ya)(ya)力的(de)壓(ya)(ya)(ya)緊而達(da)到(dao)密(mi)封(feng)的(de)軸向端(duan)(duan)面密(mi)封(feng)裝(zhuang)置。動環和靜(jing)環的(de)端(duan)(duan)面組成一(yi)對摩擦副,動環靠密(mi)封(feng)室中液...
熱水泵(beng)集式機械密(mi)封是指安(an)裝運行在泵(beng)類設備中起動態密(mi)封作(zuo)用的裝置,避免水泵(beng)蝸殼中的流體介質通過泵(beng)軸流出。由于水泵(beng)多(duo)為輸(shu)送(song)流體介質,具(ju)有水平安(an)裝、高轉速、高壓力、帶...
反壓狀(zhuang)態是不良的(de)工(gong)作狀(zhuang)態,介質中的(de)顆粒、雜質很容易進入密(mi)封(feng)面(mian),使密(mi)封(feng)失(shi)效(xiao)。磨軸的(de)主要件為橡(xiang)膠波(bo)紋管,且由(you)于(yu)上端密(mi)封(feng)面(mian)處(chu)于(yu)不良潤滑狀(zhuang)態,動靜環之間的(de)摩擦力矩大于(yu)橡(xiang)...
