機(ji)械密(mi)(mi)封是一種通(tong)用的軸封裝置，密(mi)(mi)封效(xiao)(xiao)果好，可(ke)(ke)達到介(jie)質無泄露(lu)，在(zai)普通(tong)泵中一般(ban)可(ke)(ke)運行(xing)1~2年或更長時間。用來(lai)減少(shao)(shao)機(ji)器的內漏、外漏和穿(chuan)漏，提(ti)高機(ji)器容(rong)積效(xiao)(xiao)率。減少(shao)(shao)摩擦損...
機械密(mi)封(feng)包括壓力控制、溫度控制、流體替換(huan)(堵塞)和雜(za)質(zhi)去(qu)除系統(tong)。在(zai)(zai)機械密(mi)封(feng)系統(tong)中(zhong)，上述系統(tong)并不同(tong)時包括在(zai)(zai)內。密(mi)封(feng)系統(tong)的(de)(de)選擇主(zhu)要(yao)取決于主(zhu)密(mi)封(feng)件的(de)(de)應用范(fan)圍。例如(ru)，如(ru)...
機械密封利用(yong)機械方式傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)，機械傳(chuan)(chuan)動(dong)(dong)(dong)在機械工程中應用(yong)非(fei)常廣(guang)泛，有多種形(xing)式，主(zhu)要包(bao)括(kuo)皮(pi)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(gua)桿蝸(gua)輪傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)動(dong)(dong)(dong)...
機(ji)械密(mi)封是(shi)靠彈性元件(繃簧、波紋(wen)管等) 和密(mi)封液體(ti)壓力在相(xiang)對運動的動環和靜環的接觸面(端(duan)(duan)面)上發作一恰當的壓緊(jin)力(比壓)使(shi)兩個亮光、 平直的端(duan)(duan)面緊(jin)密(mi)貼合；端(duan)(duan)面間...
機(ji)械(xie)密封是一種依靠彈性元(yuan)件對(dui)動、靜環(huan)端(duan)(duan)面(mian)密封副(fu)(fu)的預緊和介質壓力(li)與彈性元(yuan)件壓力(li)的壓緊而(er)達到密封的軸向(xiang)端(duan)(duan)面(mian)密封裝置。動環(huan)和靜環(huan)的端(duan)(duan)面(mian)組(zu)成一對(dui)摩(mo)擦副(fu)(fu)，動環(huan)靠密封室中液(ye)...
熱水(shui)泵集式(shi)機械密封(feng)是指安裝(zhuang)運行在泵類設備(bei)中(zhong)(zhong)起動態密封(feng)作用(yong)的裝(zhuang)置，避免水(shui)泵蝸殼中(zhong)(zhong)的流體介質通過泵軸流出(chu)。由于(yu)水(shui)泵多為輸送流體介質，具(ju)有(you)水(shui)平安裝(zhuang)、高(gao)轉速、高(gao)壓力、帶...
