扎囊機械密封的這三個功能一定要了解
機(ji)械密封包括壓力控(kong)制、溫度控(kong)制、流(liu)體替(ti)換(堵塞)和(he)雜質(zhi)去除系(xi)統(tong)。在機(ji)械密封系(xi)統(tong)中,上述系(xi)統(tong)并不同時包括在內。密封系(xi)統(tong)的(de)選擇(ze)主要取(qu)決于主密封件的(de)應用范圍。例如,如...

機械密封是靠彈性元件(jian)(繃簧、波紋(wen)管等) 和密封液體壓(ya)力(li)(li)在相對運動(dong)(dong)的(de)動(dong)(dong)環和靜環的(de)接觸面(端(duan)面)上發作一恰當的(de)壓(ya)緊力(li)(li)(比壓(ya))使兩(liang)個亮光(guang)、 平直的(de)端(duan)面緊密貼合(he);端(duan)面間...
機械密(mi)封是一種依靠彈(dan)性元件(jian)對動、靜環(huan)端(duan)面(mian)密(mi)封副(fu)(fu)的(de)預緊和介質壓(ya)力與彈(dan)性元件(jian)壓(ya)力的(de)壓(ya)緊而達到密(mi)封的(de)軸(zhou)向(xiang)端(duan)面(mian)密(mi)封裝(zhuang)置。動環(huan)和靜環(huan)的(de)端(duan)面(mian)組成一對摩擦副(fu)(fu),動環(huan)靠密(mi)封室(shi)中液...
熱水(shui)(shui)泵集式機械(xie)密(mi)封是指安裝(zhuang)運(yun)行在(zai)泵類(lei)設(she)備(bei)中起動態密(mi)封作(zuo)用的裝(zhuang)置,避免水(shui)(shui)泵蝸殼中的流(liu)體介質通過泵軸(zhou)流(liu)出。由于(yu)水(shui)(shui)泵多為輸送(song)流(liu)體介質,具有水(shui)(shui)平安裝(zhuang)、高轉速(su)、高壓(ya)力、帶(dai)...
反壓狀態是不良的工作狀態,介質(zhi)中的顆粒、雜質(zhi)很容易進(jin)入密(mi)(mi)封(feng)面,使密(mi)(mi)封(feng)失效。磨軸(zhou)的主要件(jian)為橡膠波(bo)紋管,且由于上端密(mi)(mi)封(feng)面處于不良潤滑狀態,動靜(jing)環(huan)之間的摩擦力矩大于橡...
