機(ji)(ji)械密封(feng)(feng)是一(yi)種通用(yong)的軸封(feng)(feng)裝置，密封(feng)(feng)效果好，可達(da)到介質無泄露(lu)，在(zai)普通泵(beng)中一(yi)般可運行1~2年或更(geng)長時間(jian)。用(yong)來減(jian)少機(ji)(ji)器(qi)的內漏、外漏和穿(chuan)漏，提(ti)高機(ji)(ji)器(qi)容積效率。減(jian)少摩擦(ca)損(sun)...
機械密封包括(kuo)壓力控(kong)(kong)制、溫度控(kong)(kong)制、流體(ti)替換(huan)(堵塞)和雜質去除系(xi)統(tong)(tong)。在(zai)機械密封系(xi)統(tong)(tong)中，上述(shu)系(xi)統(tong)(tong)并不(bu)同時(shi)包括(kuo)在(zai)內。密封系(xi)統(tong)(tong)的選擇主要取(qu)決(jue)于主密封件的應用范(fan)圍。例如(ru)，如(ru)...
機(ji)(ji)(ji)械(xie)密封利用機(ji)(ji)(ji)械(xie)方式傳(chuan)遞動(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)，機(ji)(ji)(ji)械(xie)傳(chuan)動(dong)(dong)(dong)在機(ji)(ji)(ji)械(xie)工程中(zhong)應用非常(chang)廣泛，有多(duo)種形式，主(zhu)要(yao)包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)、齒輪(lun)傳(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)動(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)...
機械(xie)密封是(shi)靠(kao)彈(dan)性元件(繃簧(huang)、波紋(wen)管等) 和(he)密封液體壓(ya)力在相對運動(dong)的動(dong)環和(he)靜環的接(jie)觸面(mian)(mian)(端(duan)(duan)面(mian)(mian))上發作一恰(qia)當的壓(ya)緊力(比壓(ya))使(shi)兩個亮光(guang)、 平直的端(duan)(duan)面(mian)(mian)緊密貼合；端(duan)(duan)面(mian)(mian)間...
機(ji)械密封是一種依(yi)靠(kao)彈(dan)(dan)性元件(jian)對動(dong)、靜環(huan)端(duan)面密封副(fu)的預緊(jin)和介質壓力與彈(dan)(dan)性元件(jian)壓力的壓緊(jin)而達到密封的軸向端(duan)面密封裝置。動(dong)環(huan)和靜環(huan)的端(duan)面組成一對摩擦副(fu)，動(dong)環(huan)靠(kao)密封室中液...
熱水(shui)泵(beng)集(ji)式機械(xie)密封是(shi)指(zhi)安裝(zhuang)運行在泵(beng)類設備中(zhong)起動態密封作用(yong)的(de)裝(zhuang)置，避免水(shui)泵(beng)蝸(gua)殼中(zhong)的(de)流(liu)體介質通過泵(beng)軸流(liu)出。由于(yu)水(shui)泵(beng)多為輸送流(liu)體介質，具(ju)有(you)水(shui)平安裝(zhuang)、高(gao)轉速、高(gao)壓力、帶...
