機(ji)械密(mi)封(feng)(feng)是一(yi)種(zhong)通用的軸(zhou)封(feng)(feng)裝置，密(mi)封(feng)(feng)效果(guo)好，可達(da)到介質無泄露，在(zai)普通泵(beng)中(zhong)一(yi)般(ban)可運行1~2年或更(geng)長時(shi)間(jian)。用來減(jian)少機(ji)器的內漏(lou)、外(wai)漏(lou)和(he)穿漏(lou)，提(ti)高機(ji)器容積效率(lv)。減(jian)少摩擦損...
機械(xie)密(mi)封包括壓力控制、溫度控制、流體(ti)替換(堵塞)和雜質去(qu)除系(xi)統(tong)。在機械(xie)密(mi)封系(xi)統(tong)中，上(shang)述系(xi)統(tong)并不同時包括在內。密(mi)封系(xi)統(tong)的選擇主要(yao)取決(jue)于主密(mi)封件(jian)的應用范圍。例如，如...
機(ji)械密封(feng)利(li)用(yong)機(ji)械方式傳遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的傳動(dong)(dong)(dong)(dong)(dong)，機(ji)械傳動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械工程中(zhong)應用(yong)非常廣泛(fan)，有多種形式，主要(yao)包括皮帶傳動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳動(dong)(dong)(dong)(dong)(dong)、鏈傳動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳動(dong)(dong)(dong)(dong)(dong)和螺旋傳動(dong)(dong)(dong)(dong)(dong)...
機(ji)械密封是靠彈性元件(繃簧、波紋管等) 和密封液體壓力在相對運(yun)動的(de)動環和靜環的(de)接觸面(mian)(mian)(端(duan)面(mian)(mian))上發作(zuo)一恰當的(de)壓緊(jin)力(比壓)使兩個亮(liang)光、 平(ping)直的(de)端(duan)面(mian)(mian)緊(jin)密貼合；端(duan)面(mian)(mian)間...
機械密(mi)(mi)封是一種依靠(kao)彈(dan)(dan)性(xing)元件對動、靜環(huan)端(duan)面(mian)密(mi)(mi)封副的(de)預緊(jin)和介質壓(ya)力與彈(dan)(dan)性(xing)元件壓(ya)力的(de)壓(ya)緊(jin)而達到密(mi)(mi)封的(de)軸向端(duan)面(mian)密(mi)(mi)封裝置。動環(huan)和靜環(huan)的(de)端(duan)面(mian)組成一對摩擦副，動環(huan)靠(kao)密(mi)(mi)封室中液...
熱水泵(beng)集(ji)式機(ji)械密(mi)封(feng)是(shi)指安裝運行在(zai)泵(beng)類(lei)設備中起動(dong)態密(mi)封(feng)作用的裝置(zhi)，避免水泵(beng)蝸殼中的流體介(jie)質通過泵(beng)軸流出。由(you)于水泵(beng)多為輸送(song)流體介(jie)質，具(ju)有水平安裝、高(gao)(gao)轉速、高(gao)(gao)壓力、帶...
