繁峙機械密封的這三個功能一定要了解
機械密(mi)(mi)封包括壓力控制、溫(wen)度控制、流體替換(堵塞(sai))和雜(za)質(zhi)去除系(xi)統(tong)(tong)。在(zai)機械密(mi)(mi)封系(xi)統(tong)(tong)中,上述系(xi)統(tong)(tong)并不同時(shi)包括在(zai)內。密(mi)(mi)封系(xi)統(tong)(tong)的選擇主(zhu)要(yao)取決于主(zhu)密(mi)(mi)封件的應用范圍。例如,如...

機械(xie)密封利(li)用機械(xie)方(fang)式(shi)傳(chuan)(chuan)(chuan)遞動(dong)力和運動(dong)的傳(chuan)(chuan)(chuan)動(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)在機械(xie)工程(cheng)中應用非(fei)常(chang)廣泛,有(you)多種形式(shi),主要包括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)動(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)動(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)動(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)...
機械密封(feng)是靠(kao)彈性元件(繃簧(huang)、波紋管(guan)等) 和密封(feng)液(ye)體壓力在相對運動(dong)的動(dong)環和靜環的接觸(chu)面(mian)(mian)(端(duan)面(mian)(mian))上發作一(yi)恰(qia)當的壓緊力(比壓)使兩(liang)個亮光、 平直的端(duan)面(mian)(mian)緊密貼合;端(duan)面(mian)(mian)間...
機(ji)械密(mi)(mi)封(feng)是一種依靠彈(dan)性(xing)元件(jian)對動、靜(jing)環(huan)端(duan)面(mian)密(mi)(mi)封(feng)副的預(yu)緊(jin)和介質(zhi)壓(ya)(ya)力與彈(dan)性(xing)元件(jian)壓(ya)(ya)力的壓(ya)(ya)緊(jin)而達到密(mi)(mi)封(feng)的軸向端(duan)面(mian)密(mi)(mi)封(feng)裝置。動環(huan)和靜(jing)環(huan)的端(duan)面(mian)組成一對摩擦(ca)副,動環(huan)靠密(mi)(mi)封(feng)室中液...
熱水泵(beng)集式機械密封(feng)是指安(an)裝運行在(zai)泵(beng)類設(she)備中(zhong)起動態密封(feng)作用的(de)裝置,避免水泵(beng)蝸殼中(zhong)的(de)流(liu)體(ti)介(jie)(jie)質通過泵(beng)軸流(liu)出。由于水泵(beng)多為輸送流(liu)體(ti)介(jie)(jie)質,具有水平安(an)裝、高(gao)轉速(su)、高(gao)壓力、帶...
反壓狀(zhuang)態(tai)(tai)是不良的(de)工作狀(zhuang)態(tai)(tai),介質中的(de)顆(ke)粒、雜(za)質很(hen)容易進入密封(feng)面,使密封(feng)失效(xiao)。磨軸的(de)主要件為橡膠(jiao)波紋管,且(qie)由于(yu)(yu)上端(duan)密封(feng)面處(chu)于(yu)(yu)不良潤(run)滑狀(zhuang)態(tai)(tai),動靜環之間(jian)的(de)摩擦力矩(ju)大于(yu)(yu)橡...
