新田機械密封的這三個功能一定要了解
機(ji)械密(mi)封(feng)包括(kuo)壓(ya)力控(kong)制、溫度控(kong)制、流體替換(堵塞)和雜質去除系(xi)統(tong)。在機(ji)械密(mi)封(feng)系(xi)統(tong)中,上述系(xi)統(tong)并不同(tong)時包括(kuo)在內。密(mi)封(feng)系(xi)統(tong)的(de)選擇主(zhu)要取決(jue)于主(zhu)密(mi)封(feng)件的(de)應用范圍。例如,如...

機械(xie)密封利用機械(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)在機械(xie)工程(cheng)中應用非常(chang)廣泛(fan),有多種形式,主(zhu)要包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)...
機械密封是靠彈(dan)性元件(繃簧(huang)、波紋(wen)管等) 和(he)密封液體(ti)壓力在相(xiang)對運動(dong)的動(dong)環(huan)和(he)靜環(huan)的接(jie)觸面(端面)上發(fa)作一恰當的壓緊(jin)力(比(bi)壓)使兩(liang)個亮光、 平直(zhi)的端面緊(jin)密貼合;端面間...
機械密封(feng)(feng)是一(yi)種依靠彈性元件(jian)對動(dong)、靜環端面(mian)密封(feng)(feng)副(fu)的(de)(de)預(yu)緊(jin)和(he)介質壓(ya)力與彈性元件(jian)壓(ya)力的(de)(de)壓(ya)緊(jin)而(er)達到密封(feng)(feng)的(de)(de)軸(zhou)向端面(mian)密封(feng)(feng)裝(zhuang)置。動(dong)環和(he)靜環的(de)(de)端面(mian)組成一(yi)對摩擦副(fu),動(dong)環靠密封(feng)(feng)室中(zhong)液...
熱水泵(beng)(beng)集式機械密(mi)封是指安(an)裝運行在泵(beng)(beng)類設(she)備中(zhong)起動態(tai)密(mi)封作用的(de)裝置(zhi),避免水泵(beng)(beng)蝸殼中(zhong)的(de)流(liu)體介(jie)質(zhi)通(tong)過泵(beng)(beng)軸流(liu)出。由于水泵(beng)(beng)多為輸送流(liu)體介(jie)質(zhi),具有水平安(an)裝、高轉速、高壓(ya)力、帶...
反壓狀態是不(bu)良(liang)的(de)工作狀態,介(jie)質中(zhong)的(de)顆粒、雜質很容易進入密(mi)封(feng)面,使(shi)密(mi)封(feng)失效。磨(mo)軸的(de)主要(yao)件為橡膠(jiao)波紋(wen)管,且由于上端(duan)密(mi)封(feng)面處(chu)于不(bu)良(liang)潤滑狀態,動(dong)靜環(huan)之間的(de)摩擦力矩大于橡...
