江川機械密封的這三個功能一定要了解
機(ji)械密封包(bao)括(kuo)壓力控制、溫度(du)控制、流體替換(堵(du)塞)和雜(za)質去除(chu)系(xi)(xi)統。在(zai)機(ji)械密封系(xi)(xi)統中,上述(shu)系(xi)(xi)統并不同時包(bao)括(kuo)在(zai)內。密封系(xi)(xi)統的(de)選擇主要(yao)取決于主密封件(jian)的(de)應用范圍。例如,如...

機(ji)械密封利用機(ji)械方(fang)式傳(chuan)遞動(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong),機(ji)械傳(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程中應用非(fei)常(chang)廣泛,有(you)多種形式,主要包括皮帶傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條(tiao)傳(chuan)動(dong)(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)(dong)...
機械密封(feng)是靠(kao)彈(dan)性元件(繃簧、波紋管等) 和(he)密封(feng)液體壓(ya)力在(zai)相對運(yun)動的動環(huan)和(he)靜環(huan)的接觸面(端面)上發作一恰當的壓(ya)緊(jin)力(比壓(ya))使兩個亮光、 平直的端面緊(jin)密貼合;端面間...
機械密(mi)封(feng)是一(yi)種依靠(kao)(kao)彈性(xing)元(yuan)件對動、靜環(huan)(huan)(huan)端面(mian)密(mi)封(feng)副的(de)預(yu)緊和介質壓力與(yu)彈性(xing)元(yuan)件壓力的(de)壓緊而達到密(mi)封(feng)的(de)軸向端面(mian)密(mi)封(feng)裝置(zhi)。動環(huan)(huan)(huan)和靜環(huan)(huan)(huan)的(de)端面(mian)組成一(yi)對摩擦副,動環(huan)(huan)(huan)靠(kao)(kao)密(mi)封(feng)室中液...
熱水(shui)泵(beng)集式機械密(mi)封(feng)是指安裝(zhuang)運行在泵(beng)類設備(bei)中(zhong)起動態密(mi)封(feng)作用的(de)裝(zhuang)置,避免(mian)水(shui)泵(beng)蝸殼中(zhong)的(de)流(liu)體介質(zhi)通過泵(beng)軸流(liu)出(chu)。由于水(shui)泵(beng)多為輸送流(liu)體介質(zhi),具有水(shui)平安裝(zhuang)、高(gao)轉速、高(gao)壓(ya)力(li)、帶...
反壓狀態是不良(liang)的工作狀態,介質(zhi)中(zhong)的顆粒、雜質(zhi)很(hen)容(rong)易進入密(mi)封面,使(shi)密(mi)封失效。磨(mo)軸(zhou)的主要件為橡膠(jiao)波(bo)紋管,且由于上端密(mi)封面處于不良(liang)潤(run)滑狀態,動(dong)靜環之(zhi)間的摩擦力矩大于橡...
