乾縣為什么機械密封需要進行沖洗
機械密封是一種通用的軸(zhou)封裝置,密封效(xiao)果好,可(ke)達到(dao)介質無泄(xie)露,在(zai)普通泵中一般可(ke)運行1~2年或更長時間。用來減少機器(qi)的內漏、外漏和穿漏,提高機器(qi)容積效(xiao)率。減少摩(mo)擦損...

機械(xie)密(mi)封包括(kuo)壓力控制、溫度控制、流體替換(堵塞)和(he)雜質(zhi)去(qu)除系(xi)統。在機械(xie)密(mi)封系(xi)統中,上述系(xi)統并不(bu)同時包括(kuo)在內。密(mi)封系(xi)統的選擇(ze)主(zhu)要取決于主(zhu)密(mi)封件的應用范圍。例如(ru),如(ru)...
機械(xie)密封(feng)利用(yong)機械(xie)方式傳遞動(dong)(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)傳動(dong)(dong)(dong)(dong)(dong),機械(xie)傳動(dong)(dong)(dong)(dong)(dong)在機械(xie)工程(cheng)中應用(yong)非常廣泛,有(you)多種(zhong)形式,主要包(bao)括皮帶(dai)傳動(dong)(dong)(dong)(dong)(dong)、齒輪傳動(dong)(dong)(dong)(dong)(dong)、鏈傳動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳動(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳動(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳動(dong)(dong)(dong)(dong)(dong)...
機械密(mi)封是靠彈性元件(繃簧、波(bo)紋管等) 和(he)密(mi)封液體壓(ya)(ya)力(li)在相對運動(dong)的動(dong)環(huan)和(he)靜(jing)環(huan)的接觸面(mian)(mian)(端面(mian)(mian))上發作一恰當的壓(ya)(ya)緊力(li)(比壓(ya)(ya))使兩個亮光、 平直(zhi)的端面(mian)(mian)緊密(mi)貼合;端面(mian)(mian)間(jian)...
機械密封(feng)(feng)是一(yi)種依靠彈(dan)性元件對動、靜環(huan)端(duan)(duan)面密封(feng)(feng)副(fu)的(de)預緊(jin)和介質壓(ya)力與彈(dan)性元件壓(ya)力的(de)壓(ya)緊(jin)而達到密封(feng)(feng)的(de)軸向端(duan)(duan)面密封(feng)(feng)裝置。動環(huan)和靜環(huan)的(de)端(duan)(duan)面組成一(yi)對摩擦副(fu),動環(huan)靠密封(feng)(feng)室中液...
熱(re)水泵(beng)集式(shi)機械密(mi)封是指安裝(zhuang)運行在泵(beng)類設備中(zhong)(zhong)起動態密(mi)封作用的裝(zhuang)置,避免水泵(beng)蝸(gua)殼中(zhong)(zhong)的流(liu)體(ti)介質通過泵(beng)軸(zhou)流(liu)出。由于水泵(beng)多為輸送流(liu)體(ti)介質,具有(you)水平安裝(zhuang)、高(gao)轉速、高(gao)壓力、帶...
