機械密封(feng)(feng)(feng)(feng)包括壓力控(kong)制、溫度控(kong)制、流體替換(huan)(堵(du)塞)和雜(za)質去除系(xi)統(tong)。在機械密封(feng)(feng)(feng)(feng)系(xi)統(tong)中，上述系(xi)統(tong)并(bing)不(bu)同時包括在內。密封(feng)(feng)(feng)(feng)系(xi)統(tong)的選擇(ze)主要取決于主密封(feng)(feng)(feng)(feng)件的應用范(fan)圍。例如(ru)，如(ru)...
機械(xie)密封利用機械(xie)方式傳(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)在機械(xie)工程中應用非常廣泛，有(you)多(duo)種形(xing)式，主要包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(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(mi)封是(shi)靠彈性元件(jian)(繃簧(huang)、波紋管等) 和密(mi)封液體壓力在相(xiang)對運動的(de)(de)(de)動環和靜環的(de)(de)(de)接觸面(mian)(端(duan)(duan)面(mian))上發作一(yi)恰當(dang)的(de)(de)(de)壓緊(jin)力(比(bi)壓)使兩個亮光、 平直的(de)(de)(de)端(duan)(duan)面(mian)緊(jin)密(mi)貼合；端(duan)(duan)面(mian)間...
機(ji)械密(mi)封(feng)是一種依靠彈性(xing)元件對動(dong)、靜環(huan)(huan)端(duan)(duan)面密(mi)封(feng)副的預(yu)緊(jin)和介(jie)質壓力與彈性(xing)元件壓力的壓緊(jin)而達到密(mi)封(feng)的軸向端(duan)(duan)面密(mi)封(feng)裝置。動(dong)環(huan)(huan)和靜環(huan)(huan)的端(duan)(duan)面組成一對摩(mo)擦副，動(dong)環(huan)(huan)靠密(mi)封(feng)室中液(ye)...
熱水(shui)泵集式(shi)機械密封是(shi)指安(an)裝運行在泵類設備中(zhong)起動(dong)態(tai)密封作用的(de)裝置，避免水(shui)泵蝸殼中(zhong)的(de)流體介質通過泵軸流出(chu)。由于水(shui)泵多(duo)為輸(shu)送流體介質，具有水(shui)平安(an)裝、高(gao)轉速(su)、高(gao)壓力、帶...
反(fan)壓狀態(tai)(tai)是不(bu)良的(de)工作(zuo)狀態(tai)(tai)，介質中(zhong)的(de)顆粒、雜質很容易進入密封面(mian)，使密封失效。磨軸的(de)主要件(jian)為橡膠波紋管，且由于上端(duan)密封面(mian)處(chu)于不(bu)良潤滑狀態(tai)(tai)，動靜環之間的(de)摩擦力矩大于橡...
