屯城鎮為什么機械密封需要進行沖洗
機械(xie)密封是一種(zhong)通用的(de)軸封裝置,密封效果好,可(ke)達(da)到介質無泄露(lu),在普通泵中一般可(ke)運行1~2年或更長時間。用來減少機器的(de)內漏、外漏和穿漏,提高機器容積效率。減少摩擦(ca)損...

機(ji)(ji)械(xie)(xie)密(mi)(mi)封包(bao)(bao)括壓力控(kong)制、溫(wen)度控(kong)制、流體替換(堵塞)和(he)雜(za)質去(qu)除(chu)系(xi)統(tong)。在機(ji)(ji)械(xie)(xie)密(mi)(mi)封系(xi)統(tong)中,上述系(xi)統(tong)并不(bu)同時包(bao)(bao)括在內。密(mi)(mi)封系(xi)統(tong)的(de)選擇主要(yao)取(qu)決于主密(mi)(mi)封件的(de)應用(yong)范圍。例(li)如,如...
機(ji)械密封利用機(ji)械方(fang)式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)力和運動(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong),機(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)在(zai)機(ji)械工程(cheng)中應用非常廣泛(fan),有多(duo)種形(xing)式,主要(yao)包括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)、蝸(gua)(gua)桿蝸(gua)(gua)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)和螺旋(xuan)傳(chuan)(chuan)(chuan)(chuan)動(dong)...
機械密封是靠彈(dan)性(xing)元件(繃(beng)簧、波紋管等) 和密封液體壓力在(zai)相對運動(dong)的動(dong)環(huan)和靜(jing)環(huan)的接觸面(mian)(端(duan)面(mian))上(shang)發(fa)作一恰當(dang)的壓緊力(比壓)使兩個亮光、 平(ping)直的端(duan)面(mian)緊密貼合;端(duan)面(mian)間...
機械密封(feng)(feng)是一種依靠彈性元(yuan)件(jian)對動(dong)、靜(jing)環端面(mian)密封(feng)(feng)副的(de)預緊(jin)和(he)介質壓力與彈性元(yuan)件(jian)壓力的(de)壓緊(jin)而達到(dao)密封(feng)(feng)的(de)軸向端面(mian)密封(feng)(feng)裝置。動(dong)環和(he)靜(jing)環的(de)端面(mian)組成(cheng)一對摩擦副,動(dong)環靠密封(feng)(feng)室(shi)中(zhong)液...
熱水(shui)(shui)泵集式(shi)機(ji)械密封是指安裝(zhuang)(zhuang)運行(xing)在泵類設備(bei)中(zhong)起動態密封作(zuo)用的裝(zhuang)(zhuang)置,避免水(shui)(shui)泵蝸殼中(zhong)的流體介(jie)質通過(guo)泵軸流出。由于水(shui)(shui)泵多為輸送(song)流體介(jie)質,具有(you)水(shui)(shui)平安裝(zhuang)(zhuang)、高轉速、高壓力、帶...
