甘肅機械密封的這三個功能一定要了解
機(ji)械密封(feng)(feng)包括壓力控制、溫(wen)度控制、流體替換(堵塞)和雜質(zhi)去除系統。在(zai)機(ji)械密封(feng)(feng)系統中(zhong),上(shang)述系統并不同時(shi)包括在(zai)內(nei)。密封(feng)(feng)系統的選擇主(zhu)要取決于(yu)主(zhu)密封(feng)(feng)件的應(ying)用范(fan)圍。例如,如...

機(ji)(ji)械(xie)密封(feng)利(li)用(yong)機(ji)(ji)械(xie)方式傳(chuan)(chuan)遞動(dong)(dong)力(li)和運(yun)動(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong),機(ji)(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)在(zai)機(ji)(ji)械(xie)工程中應用(yong)非常廣泛,有(you)多種形式,主要包括皮帶傳(chuan)(chuan)動(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)和螺(luo)旋傳(chuan)(chuan)動(dong)(dong)...
機械密封是靠彈性元件(繃(beng)簧、波紋管(guan)等) 和(he)(he)密封液(ye)體(ti)壓力(li)在相對運動的(de)動環(huan)和(he)(he)靜環(huan)的(de)接(jie)觸(chu)面(mian)(mian)(端面(mian)(mian))上發作一(yi)恰當的(de)壓緊力(li)(比壓)使兩個(ge)亮(liang)光、 平直的(de)端面(mian)(mian)緊密貼合(he);端面(mian)(mian)間(jian)...
機械密封(feng)是一(yi)種依靠彈性(xing)元(yuan)件(jian)對動、靜環(huan)(huan)端(duan)(duan)面(mian)密封(feng)副的(de)預緊(jin)和介質壓(ya)力與彈性(xing)元(yuan)件(jian)壓(ya)力的(de)壓(ya)緊(jin)而達到密封(feng)的(de)軸向(xiang)端(duan)(duan)面(mian)密封(feng)裝(zhuang)置。動環(huan)(huan)和靜環(huan)(huan)的(de)端(duan)(duan)面(mian)組成一(yi)對摩(mo)擦副,動環(huan)(huan)靠密封(feng)室中液(ye)...
熱水(shui)(shui)泵(beng)(beng)集式機械密封是指安(an)(an)裝(zhuang)運行在泵(beng)(beng)類設備中(zhong)起(qi)動(dong)態密封作用(yong)的裝(zhuang)置,避免水(shui)(shui)泵(beng)(beng)蝸殼中(zhong)的流(liu)體介質通過泵(beng)(beng)軸(zhou)流(liu)出。由(you)于(yu)水(shui)(shui)泵(beng)(beng)多為輸送(song)流(liu)體介質,具有(you)水(shui)(shui)平安(an)(an)裝(zhuang)、高轉速、高壓力、帶...
反壓狀(zhuang)態(tai)(tai)是不(bu)良的工作狀(zhuang)態(tai)(tai),介(jie)質中(zhong)的顆粒、雜質很容(rong)易進入密封(feng)面,使密封(feng)失效(xiao)。磨軸的主要件為(wei)橡(xiang)膠波紋管,且由于上端(duan)密封(feng)面處于不(bu)良潤滑狀(zhuang)態(tai)(tai),動靜環(huan)之間的摩擦力矩大于橡(xiang)...
