定襄機械密封的這三個功能一定要了解
機械密(mi)封(feng)包括壓力控制、溫度控制、流(liu)體替換(堵塞)和雜質去除系(xi)統(tong)。在(zai)(zai)機械密(mi)封(feng)系(xi)統(tong)中,上述系(xi)統(tong)并不(bu)同時包括在(zai)(zai)內。密(mi)封(feng)系(xi)統(tong)的選擇(ze)主要取決于主密(mi)封(feng)件的應用范圍。例如,如...

機(ji)械密封(feng)利用(yong)機(ji)械方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械工程中應用(yong)非(fei)常廣泛(fan),有多(duo)種形式,主(zhu)要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿(gan)蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)...
機械(xie)密(mi)(mi)封(feng)是靠彈性元(yuan)件(繃簧、波紋管等(deng)) 和密(mi)(mi)封(feng)液體壓(ya)力在相對(dui)運動(dong)的(de)動(dong)環和靜環的(de)接觸面(mian)(端(duan)面(mian))上(shang)發作一恰當的(de)壓(ya)緊力(比壓(ya))使兩個亮光、 平直(zhi)的(de)端(duan)面(mian)緊密(mi)(mi)貼合;端(duan)面(mian)間...
機(ji)械(xie)密(mi)(mi)封(feng)是一(yi)種依靠彈性(xing)元件對動(dong)(dong)、靜(jing)環端面(mian)密(mi)(mi)封(feng)副的(de)預緊和介(jie)質壓(ya)力與彈性(xing)元件壓(ya)力的(de)壓(ya)緊而達到(dao)密(mi)(mi)封(feng)的(de)軸向端面(mian)密(mi)(mi)封(feng)裝置。動(dong)(dong)環和靜(jing)環的(de)端面(mian)組(zu)成一(yi)對摩擦副,動(dong)(dong)環靠密(mi)(mi)封(feng)室中液...
熱水(shui)泵(beng)集式機械密封是(shi)指安(an)裝(zhuang)運行(xing)在泵(beng)類(lei)設備中(zhong)起動態(tai)密封作用的裝(zhuang)置,避免水(shui)泵(beng)蝸殼中(zhong)的流體(ti)介質通過泵(beng)軸流出。由于水(shui)泵(beng)多為輸送流體(ti)介質,具(ju)有水(shui)平(ping)安(an)裝(zhuang)、高(gao)轉速、高(gao)壓力(li)、帶...
反壓狀態(tai)是不(bu)良的工作狀態(tai),介質中的顆粒、雜質很容易(yi)進(jin)入密(mi)封(feng)面(mian),使密(mi)封(feng)失(shi)效(xiao)。磨軸的主要件為橡膠波(bo)紋管(guan),且由于(yu)上(shang)端密(mi)封(feng)面(mian)處于(yu)不(bu)良潤滑狀態(tai),動靜環之間的摩擦力(li)矩(ju)大(da)于(yu)橡...
