機(ji)械密(mi)封(feng)包括壓(ya)力控(kong)制(zhi)(zhi)、溫度(du)控(kong)制(zhi)(zhi)、流體替換(堵塞)和雜質(zhi)去(qu)除系統(tong)。在機(ji)械密(mi)封(feng)系統(tong)中，上述系統(tong)并不(bu)同時包括在內。密(mi)封(feng)系統(tong)的選擇主要取決于(yu)主密(mi)封(feng)件的應(ying)用(yong)范圍。例如，如...
機械密封利用機械方(fang)式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械工程(cheng)中(zhong)應用非常廣(guang)泛，有多種形(xing)式，主要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒輪齒條(tiao)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)...
機械密(mi)封(feng)是靠彈性元件(繃簧、波紋管等) 和密(mi)封(feng)液(ye)體(ti)壓(ya)(ya)力(li)在相(xiang)對運(yun)動(dong)的(de)動(dong)環和靜環的(de)接觸面(mian)(mian)(端(duan)面(mian)(mian))上發作一恰當(dang)的(de)壓(ya)(ya)緊(jin)力(li)(比壓(ya)(ya))使(shi)兩個亮光、 平(ping)直的(de)端(duan)面(mian)(mian)緊(jin)密(mi)貼合；端(duan)面(mian)(mian)間...
機械密封(feng)是(shi)一種(zhong)依靠(kao)(kao)彈(dan)(dan)性元件對動、靜環(huan)端面(mian)密封(feng)副的預緊和介質壓(ya)(ya)力與彈(dan)(dan)性元件壓(ya)(ya)力的壓(ya)(ya)緊而達(da)到(dao)密封(feng)的軸向端面(mian)密封(feng)裝置。動環(huan)和靜環(huan)的端面(mian)組成(cheng)一對摩擦副，動環(huan)靠(kao)(kao)密封(feng)室中液...
熱水(shui)(shui)泵(beng)集式機械(xie)密封(feng)是指安裝(zhuang)運行在泵(beng)類設(she)備中(zhong)起(qi)動態密封(feng)作用(yong)的裝(zhuang)置，避免水(shui)(shui)泵(beng)蝸殼中(zhong)的流體(ti)介(jie)質(zhi)通過泵(beng)軸流出。由于水(shui)(shui)泵(beng)多為輸送流體(ti)介(jie)質(zhi)，具有(you)水(shui)(shui)平安裝(zhuang)、高(gao)轉(zhuan)速(su)、高(gao)壓力、帶...
