龍沙機械密封的這三個功能一定要了解
機(ji)械密(mi)封包括壓(ya)力(li)控制、溫度控制、流(liu)體替(ti)換(堵塞)和雜質(zhi)去除(chu)系(xi)統(tong)(tong)。在機(ji)械密(mi)封系(xi)統(tong)(tong)中，上述(shu)系(xi)統(tong)(tong)并不(bu)同時包括在內。密(mi)封系(xi)統(tong)(tong)的選擇主(zhu)要取決于主(zhu)密(mi)封件(jian)的應用范圍(wei)。例如，如...

機(ji)械(xie)密封利用機(ji)械(xie)方(fang)式(shi)傳(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工程(cheng)中應(ying)用非常廣(guang)泛，有多種形式(shi)，主要包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)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(chi)輪齒(chi)條(tiao)傳(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)動(dong)(dong)(dong)...
機械密封(feng)是靠彈(dan)性元(yuan)件(繃簧、波(bo)紋管等) 和密封(feng)液體壓(ya)力在相對運動的(de)(de)動環(huan)和靜環(huan)的(de)(de)接觸面(mian)(mian)(端(duan)面(mian)(mian))上發(fa)作一恰當的(de)(de)壓(ya)緊(jin)力(比(bi)壓(ya))使(shi)兩(liang)個亮光(guang)、 平直的(de)(de)端(duan)面(mian)(mian)緊(jin)密貼(tie)合；端(duan)面(mian)(mian)間(jian)...
機(ji)械密封是一種依靠彈性元件對(dui)動、靜環(huan)(huan)(huan)端面(mian)(mian)密封副(fu)的(de)預(yu)緊和介質(zhi)壓(ya)力與彈性元件壓(ya)力的(de)壓(ya)緊而達(da)到密封的(de)軸向端面(mian)(mian)密封裝置(zhi)。動環(huan)(huan)(huan)和靜環(huan)(huan)(huan)的(de)端面(mian)(mian)組(zu)成(cheng)一對(dui)摩擦(ca)副(fu)，動環(huan)(huan)(huan)靠密封室(shi)中液...
熱(re)水泵(beng)集式機械(xie)密(mi)(mi)封(feng)是指安(an)裝運行在泵(beng)類設備中起動態密(mi)(mi)封(feng)作用(yong)的裝置(zhi)，避免水泵(beng)蝸殼中的流(liu)體介質通過泵(beng)軸流(liu)出(chu)。由(you)于水泵(beng)多(duo)為輸送(song)流(liu)體介質，具有(you)水平安(an)裝、高轉(zhuan)速(su)、高壓(ya)力、帶...
反壓(ya)狀態(tai)是不(bu)良(liang)的工作狀態(tai)，介(jie)質(zhi)中的顆粒、雜質(zhi)很容易進入密(mi)封面，使(shi)密(mi)封失(shi)效。磨軸的主要件為(wei)橡膠(jiao)波紋(wen)管，且由于上(shang)端密(mi)封面處于不(bu)良(liang)潤滑狀態(tai)，動靜(jing)環之間的摩擦(ca)力矩大于橡...
