機械密(mi)(mi)封(feng)包(bao)括壓力控(kong)制、溫度(du)控(kong)制、流體替換(huan)(堵塞(sai))和(he)雜質(zhi)去除系統(tong)。在機械密(mi)(mi)封(feng)系統(tong)中(zhong)，上述系統(tong)并不同時(shi)包(bao)括在內。密(mi)(mi)封(feng)系統(tong)的(de)選(xuan)擇(ze)主(zhu)要取決于主(zhu)密(mi)(mi)封(feng)件(jian)的(de)應用范圍。例如(ru)(ru)，如(ru)(ru)...
機(ji)械密封利用機(ji)械方式傳(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)，機(ji)械傳(chuan)動(dong)(dong)(dong)在機(ji)械工程中應用非常廣泛，有多種(zhong)形式，主要包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)、齒輪齒條傳(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)...
機械密(mi)(mi)封(feng)是(shi)靠彈性元件(繃(beng)簧(huang)、波紋管等) 和密(mi)(mi)封(feng)液(ye)體壓(ya)力在相對運動(dong)的動(dong)環和靜環的接觸(chu)面(mian)(mian)(mian)(端面(mian)(mian)(mian))上(shang)發作一恰(qia)當(dang)的壓(ya)緊力(比壓(ya))使兩個亮光、 平直的端面(mian)(mian)(mian)緊密(mi)(mi)貼合；端面(mian)(mian)(mian)間(jian)...
機械密(mi)封(feng)(feng)(feng)是一種(zhong)依靠彈(dan)性元(yuan)件對(dui)動(dong)、靜(jing)環端(duan)面(mian)密(mi)封(feng)(feng)(feng)副的預緊和介質壓力與(yu)彈(dan)性元(yuan)件壓力的壓緊而達(da)到密(mi)封(feng)(feng)(feng)的軸向端(duan)面(mian)密(mi)封(feng)(feng)(feng)裝置。動(dong)環和靜(jing)環的端(duan)面(mian)組(zu)成一對(dui)摩(mo)擦(ca)副，動(dong)環靠密(mi)封(feng)(feng)(feng)室中液...
熱(re)水(shui)(shui)泵(beng)(beng)集式機械密封是指安(an)裝(zhuang)運行(xing)在泵(beng)(beng)類設備(bei)中(zhong)起動(dong)態密封作用(yong)的(de)裝(zhuang)置，避免水(shui)(shui)泵(beng)(beng)蝸殼中(zhong)的(de)流(liu)體介質通過泵(beng)(beng)軸流(liu)出(chu)。由于水(shui)(shui)泵(beng)(beng)多為輸送流(liu)體介質，具有(you)水(shui)(shui)平安(an)裝(zhuang)、高轉(zhuan)速、高壓(ya)力、帶...
反壓狀(zhuang)態(tai)是不良的(de)(de)工(gong)作狀(zhuang)態(tai)，介質中的(de)(de)顆(ke)粒、雜質很(hen)容易進(jin)入密(mi)封(feng)面，使(shi)密(mi)封(feng)失效。磨軸的(de)(de)主要件為橡膠波紋管(guan)，且由于上(shang)端密(mi)封(feng)面處于不良潤(run)滑狀(zhuang)態(tai)，動靜環之間的(de)(de)摩(mo)擦(ca)力矩大于橡...
