機械密封(feng)(feng)包括(kuo)壓(ya)力控制、溫(wen)度控制、流體替換(堵(du)塞(sai))和雜(za)質去除系(xi)(xi)統(tong)(tong)。在(zai)機械密封(feng)(feng)系(xi)(xi)統(tong)(tong)中，上述系(xi)(xi)統(tong)(tong)并(bing)不同時包括(kuo)在(zai)內。密封(feng)(feng)系(xi)(xi)統(tong)(tong)的選擇主要取決于主密封(feng)(feng)件的應用范圍。例如(ru)，如(ru)...
機(ji)械(xie)密封利用(yong)機(ji)械(xie)方(fang)式傳(chuan)遞(di)動(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)在(zai)機(ji)械(xie)工(gong)程中應用(yong)非常廣泛，有多種形式，主要(yao)包括皮帶傳(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)動(dong)(dong)(dong)、齒輪齒條傳(chuan)動(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)動(dong)(dong)(dong)...
機械密(mi)封是靠彈性元件(繃簧、波紋管等) 和(he)密(mi)封液(ye)體壓(ya)力在相對運(yun)動的動環(huan)和(he)靜環(huan)的接觸面(端面)上(shang)發作一恰當的壓(ya)緊力(比壓(ya))使兩(liang)個亮光、 平直的端面緊密(mi)貼合；端面間...
機械(xie)密封是一種依靠彈性元件(jian)對(dui)動、靜環(huan)端(duan)(duan)面(mian)密封副的預(yu)緊(jin)(jin)和介質壓(ya)力(li)與彈性元件(jian)壓(ya)力(li)的壓(ya)緊(jin)(jin)而達到密封的軸向(xiang)端(duan)(duan)面(mian)密封裝置。動環(huan)和靜環(huan)的端(duan)(duan)面(mian)組(zu)成一對(dui)摩擦副，動環(huan)靠密封室中液...
熱水(shui)泵(beng)集式機械(xie)密(mi)封是指安裝運行在泵(beng)類(lei)設備中起(qi)動態密(mi)封作(zuo)用的(de)(de)裝置，避免水(shui)泵(beng)蝸殼中的(de)(de)流(liu)體介質通過泵(beng)軸流(liu)出。由于(yu)水(shui)泵(beng)多為輸(shu)送(song)流(liu)體介質，具有水(shui)平安裝、高(gao)轉速、高(gao)壓力、帶...
反(fan)壓狀(zhuang)(zhuang)態(tai)(tai)是不(bu)良的(de)(de)工(gong)作(zuo)狀(zhuang)(zhuang)態(tai)(tai)，介質(zhi)中的(de)(de)顆粒、雜質(zhi)很(hen)容(rong)易(yi)進(jin)入密(mi)封(feng)(feng)面(mian)，使(shi)密(mi)封(feng)(feng)失效。磨軸的(de)(de)主要件為(wei)橡(xiang)膠波紋管(guan)，且由于(yu)上端密(mi)封(feng)(feng)面(mian)處(chu)于(yu)不(bu)良潤(run)滑狀(zhuang)(zhuang)態(tai)(tai)，動(dong)靜環之間的(de)(de)摩擦力矩大于(yu)橡(xiang)...
