景德鎮機械密封的這三個功能一定要了解
機(ji)械密封(feng)包括壓力控制(zhi)、溫度控制(zhi)、流體替換(堵(du)塞)和雜質去除系(xi)統。在(zai)機(ji)械密封(feng)系(xi)統中,上(shang)述系(xi)統并不同時包括在(zai)內。密封(feng)系(xi)統的選擇(ze)主要取(qu)決(jue)于主密封(feng)件的應(ying)用范圍。例(li)如,如...

機械密封利用機械方式(shi)傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)(dong),機械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機械工(gong)程中(zhong)應用非常廣泛,有多(duo)種形式(shi),主要(yao)包括皮帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪齒條(tiao)傳(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)動(dong)(dong)(dong)(dong)(dong)...
機械密封是靠(kao)彈性元件(繃簧、波(bo)紋管等) 和密封液體壓(ya)力在相對運動的(de)動環(huan)和靜(jing)環(huan)的(de)接觸(chu)面(mian)(mian)(端面(mian)(mian))上(shang)發作(zuo)一恰當的(de)壓(ya)緊力(比(bi)壓(ya))使兩個亮光、 平直的(de)端面(mian)(mian)緊密貼(tie)合;端面(mian)(mian)間(jian)...
機械密(mi)封(feng)是一種依靠彈(dan)性元件對動、靜環(huan)端面(mian)密(mi)封(feng)副的(de)預緊(jin)和介質壓力與彈(dan)性元件壓力的(de)壓緊(jin)而達到密(mi)封(feng)的(de)軸向端面(mian)密(mi)封(feng)裝置(zhi)。動環(huan)和靜環(huan)的(de)端面(mian)組成一對摩擦副,動環(huan)靠密(mi)封(feng)室中液...
熱水(shui)(shui)(shui)泵(beng)(beng)集式機械密封是指安(an)裝(zhuang)運行在泵(beng)(beng)類(lei)設備中起動態密封作用的裝(zhuang)置,避免水(shui)(shui)(shui)泵(beng)(beng)蝸(gua)殼中的流體(ti)介質通過泵(beng)(beng)軸流出(chu)。由于水(shui)(shui)(shui)泵(beng)(beng)多為輸(shu)送流體(ti)介質,具有水(shui)(shui)(shui)平安(an)裝(zhuang)、高轉(zhuan)速、高壓(ya)力、帶...
反壓(ya)狀態是不(bu)良的(de)工作狀態,介質(zhi)中(zhong)的(de)顆(ke)粒、雜質(zhi)很(hen)容易(yi)進入密封(feng)(feng)面,使密封(feng)(feng)失效。磨軸的(de)主要件為橡(xiang)膠(jiao)波紋管,且由于(yu)上端(duan)密封(feng)(feng)面處于(yu)不(bu)良潤滑狀態,動(dong)靜(jing)環之間的(de)摩擦力矩大(da)于(yu)橡(xiang)...
