阜龍鄉為什么機械密封需要進行沖洗
機(ji)(ji)械密封是一種通用的(de)(de)軸封裝(zhuang)置,密封效果(guo)好(hao),可(ke)達到介質無(wu)泄(xie)露,在普通泵中一般可(ke)運行1~2年或更長時間。用來減(jian)少(shao)機(ji)(ji)器的(de)(de)內漏(lou)、外漏(lou)和(he)穿漏(lou),提高機(ji)(ji)器容積效率。減(jian)少(shao)摩擦(ca)損...

機械密(mi)(mi)封(feng)包括壓力控(kong)制、溫度控(kong)制、流體替(ti)換(堵塞)和(he)雜質去除系(xi)(xi)統(tong)(tong)。在機械密(mi)(mi)封(feng)系(xi)(xi)統(tong)(tong)中,上述系(xi)(xi)統(tong)(tong)并不(bu)同時包括在內(nei)。密(mi)(mi)封(feng)系(xi)(xi)統(tong)(tong)的選擇(ze)主(zhu)要取決于主(zhu)密(mi)(mi)封(feng)件的應(ying)用范圍(wei)。例(li)如,如...
機械(xie)密封(feng)利(li)用機械(xie)方式(shi)傳(chuan)遞(di)動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong),機械(xie)傳(chuan)動(dong)(dong)(dong)在機械(xie)工程(cheng)中(zhong)應(ying)用非常廣泛,有多種(zhong)形(xing)式(shi),主要包(bao)括皮帶(dai)傳(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)動(dong)(dong)(dong)和螺(luo)旋傳(chuan)動(dong)(dong)(dong)...
機械(xie)密(mi)封是靠彈性元件(繃(beng)簧、波紋管等) 和密(mi)封液體(ti)壓(ya)力在相對運(yun)動的(de)動環和靜環的(de)接觸面(mian)(端面(mian))上發(fa)作一恰當的(de)壓(ya)緊力(比壓(ya))使兩個亮光、 平直的(de)端面(mian)緊密(mi)貼合;端面(mian)間...
機(ji)械密封(feng)是一種依靠(kao)彈(dan)性元(yuan)件對(dui)動、靜(jing)環(huan)端(duan)面密封(feng)副的預(yu)緊和介質壓(ya)力與彈(dan)性元(yuan)件壓(ya)力的壓(ya)緊而達到密封(feng)的軸(zhou)向端(duan)面密封(feng)裝置。動環(huan)和靜(jing)環(huan)的端(duan)面組(zu)成一對(dui)摩擦副,動環(huan)靠(kao)密封(feng)室中液...
熱水(shui)(shui)泵(beng)集式機械密(mi)封(feng)(feng)是(shi)指安裝運行在泵(beng)類設(she)備中起動態密(mi)封(feng)(feng)作(zuo)用的裝置,避免水(shui)(shui)泵(beng)蝸殼中的流體介(jie)質通過泵(beng)軸流出。由于(yu)水(shui)(shui)泵(beng)多(duo)為輸(shu)送流體介(jie)質,具(ju)有水(shui)(shui)平安裝、高轉速、高壓力、帶...
