吉木薩爾機械密封的這三個功能一定要了解
機械密封(feng)包括壓力控制、溫度控制、流體(ti)替換(堵塞)和雜質去(qu)除系(xi)(xi)統(tong)。在(zai)機械密封(feng)系(xi)(xi)統(tong)中,上述系(xi)(xi)統(tong)并不(bu)同時包括在(zai)內。密封(feng)系(xi)(xi)統(tong)的選(xuan)擇主(zhu)要取決于主(zhu)密封(feng)件的應用范圍。例如(ru),如(ru)...

機(ji)械密封利(li)用(yong)機(ji)械方式(shi)傳(chuan)(chuan)遞動(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械工程中應用(yong)非(fei)常廣泛,有(you)多(duo)種形式(shi),主要包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)動(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)...
機(ji)械密封(feng)是靠(kao)彈(dan)性元件(繃簧、波紋管等) 和密封(feng)液體壓(ya)力在(zai)相對(dui)運動的動環和靜環的接觸面(mian)(端(duan)面(mian))上發(fa)作一恰當的壓(ya)緊(jin)力(比壓(ya))使兩(liang)個亮光(guang)、 平直的端(duan)面(mian)緊(jin)密貼(tie)合;端(duan)面(mian)間...
機械密(mi)(mi)封是一種(zhong)依靠彈性元件(jian)對(dui)動、靜環端面(mian)密(mi)(mi)封副的(de)預緊和(he)介(jie)質壓(ya)力與(yu)彈性元件(jian)壓(ya)力的(de)壓(ya)緊而(er)達到密(mi)(mi)封的(de)軸向端面(mian)密(mi)(mi)封裝置。動環和(he)靜環的(de)端面(mian)組(zu)成一對(dui)摩(mo)擦(ca)副,動環靠密(mi)(mi)封室中(zhong)液...
熱水(shui)泵(beng)集式(shi)機械密(mi)封是指(zhi)安(an)裝運(yun)行(xing)在泵(beng)類設(she)備中(zhong)起動(dong)態密(mi)封作(zuo)用的裝置,避免水(shui)泵(beng)蝸殼中(zhong)的流(liu)體(ti)介質通過泵(beng)軸流(liu)出。由于水(shui)泵(beng)多(duo)為輸(shu)送流(liu)體(ti)介質,具有水(shui)平(ping)安(an)裝、高轉(zhuan)速、高壓力、帶...
反壓狀(zhuang)態是不良的工作狀(zhuang)態,介質(zhi)中的顆粒、雜(za)質(zhi)很容易進(jin)入密封(feng)面,使密封(feng)失效。磨(mo)軸的主要件為橡(xiang)膠波紋管,且(qie)由于(yu)上(shang)端密封(feng)面處于(yu)不良潤滑狀(zhuang)態,動(dong)靜環(huan)之間的摩擦(ca)力矩大于(yu)橡(xiang)...
