青羊為什么機械密封需要進行沖洗
機械(xie)密封是一種通用的軸封裝置,密封效果好,可達到介質無泄(xie)露,在(zai)普通泵中一般可運行1~2年或更(geng)長時間。用來減少機器(qi)的內漏、外漏和(he)穿漏,提高(gao)機器(qi)容積效率。減少摩擦(ca)損...

機械密封包(bao)括壓力控制(zhi)、溫度(du)控制(zhi)、流體替換(堵(du)塞)和雜質去除系統。在機械密封系統中,上述系統并不(bu)同時包(bao)括在內(nei)。密封系統的選擇主要取決于主密封件的應用范圍(wei)。例(li)如(ru),如(ru)...
機械密封利用機械方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong),機械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機械工程中應用非常廣泛(fan),有多種形式,主(zhu)要包(bao)括皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)(chi)輪(lun)(lun)齒(chi)(chi)(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機(ji)械(xie)密(mi)封(feng)是靠彈性元件(jian)(繃簧(huang)、波紋管等) 和(he)密(mi)封(feng)液(ye)體壓(ya)力在相對運動的動環(huan)和(he)靜環(huan)的接觸面(mian)(mian)(端(duan)(duan)面(mian)(mian))上(shang)發(fa)作(zuo)一恰當的壓(ya)緊力(比壓(ya))使(shi)兩(liang)個亮光、 平(ping)直的端(duan)(duan)面(mian)(mian)緊密(mi)貼合;端(duan)(duan)面(mian)(mian)間(jian)...
機械密封(feng)(feng)是一種依靠彈性元件對(dui)動(dong)、靜環(huan)端面(mian)密封(feng)(feng)副的(de)預緊和(he)(he)介質壓力與彈性元件壓力的(de)壓緊而達到密封(feng)(feng)的(de)軸向端面(mian)密封(feng)(feng)裝置。動(dong)環(huan)和(he)(he)靜環(huan)的(de)端面(mian)組成一對(dui)摩(mo)擦(ca)副,動(dong)環(huan)靠密封(feng)(feng)室中液...
熱水泵(beng)集式(shi)機械密封(feng)是指安裝(zhuang)運行在(zai)泵(beng)類設備中(zhong)起動(dong)態(tai)密封(feng)作用的(de)裝(zhuang)置,避免水泵(beng)蝸殼中(zhong)的(de)流體介(jie)(jie)質通(tong)過泵(beng)軸流出。由于水泵(beng)多為輸送流體介(jie)(jie)質,具有(you)水平安裝(zhuang)、高(gao)轉速、高(gao)壓力(li)、帶...
