老城鎮機械密封的這三個功能一定要了解
機械密(mi)封包括壓(ya)力控(kong)制、溫度控(kong)制、流體替換(堵塞)和雜質去除系(xi)統(tong)。在機械密(mi)封系(xi)統(tong)中,上(shang)述系(xi)統(tong)并(bing)不同時包括在內(nei)。密(mi)封系(xi)統(tong)的(de)(de)選擇主要取(qu)決于主密(mi)封件的(de)(de)應用范(fan)圍。例如(ru),如(ru)...

機械密(mi)封是靠彈性元(yuan)件(繃簧、波紋管等) 和(he)密(mi)封液體壓力在相(xiang)對(dui)運動(dong)的動(dong)環和(he)靜環的接觸面(mian)(mian)(端(duan)面(mian)(mian))上發作一恰當的壓緊力(比壓)使(shi)兩個亮(liang)光、 平直(zhi)的端(duan)面(mian)(mian)緊密(mi)貼合;端(duan)面(mian)(mian)間(jian)...
機械(xie)密(mi)封(feng)是一種依(yi)靠彈性元(yuan)件對動(dong)、靜環(huan)(huan)端(duan)面(mian)密(mi)封(feng)副的(de)預緊和(he)介質壓力(li)與彈性元(yuan)件壓力(li)的(de)壓緊而達到密(mi)封(feng)的(de)軸向(xiang)端(duan)面(mian)密(mi)封(feng)裝置(zhi)。動(dong)環(huan)(huan)和(he)靜環(huan)(huan)的(de)端(duan)面(mian)組成(cheng)一對摩擦(ca)副,動(dong)環(huan)(huan)靠密(mi)封(feng)室中液...
熱水泵(beng)集式機械密(mi)封是指安裝(zhuang)運行(xing)在泵(beng)類(lei)設備中(zhong)起動態密(mi)封作(zuo)用的裝(zhuang)置(zhi),避免(mian)水泵(beng)蝸殼中(zhong)的流體介(jie)(jie)質通過泵(beng)軸(zhou)流出。由于水泵(beng)多為輸(shu)送流體介(jie)(jie)質,具(ju)有水平安裝(zhuang)、高(gao)轉速、高(gao)壓力、帶...
反壓狀(zhuang)態是不良(liang)的工作狀(zhuang)態,介質中的顆粒、雜質很容(rong)易進入密(mi)(mi)封(feng)面,使(shi)密(mi)(mi)封(feng)失效。磨軸的主要件為橡膠波紋(wen)管,且由于(yu)上端密(mi)(mi)封(feng)面處(chu)于(yu)不良(liang)潤滑狀(zhuang)態,動靜環之(zhi)間的摩擦力矩大于(yu)橡...
