機(ji)(ji)(ji)械(xie)密封(feng)(feng)是(shi)一種(zhong)通用的軸封(feng)(feng)裝置，密封(feng)(feng)效果好，可達到介(jie)質無泄露，在普通泵中(zhong)一般可運行(xing)1~2年或更(geng)長時間。用來減少(shao)機(ji)(ji)(ji)器(qi)的內漏(lou)、外漏(lou)和(he)穿漏(lou)，提(ti)高機(ji)(ji)(ji)器(qi)容積(ji)效率。減少(shao)摩擦損...
機(ji)械密封包(bao)括壓(ya)力(li)控(kong)制、溫度控(kong)制、流體替換(堵塞)和(he)雜質去除系統。在機(ji)械密封系統中，上述系統并不同(tong)時包(bao)括在內。密封系統的選擇主(zhu)要取決(jue)于主(zhu)密封件(jian)的應用范圍。例如，如...
機械(xie)密封利用(yong)機械(xie)方式(shi)(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)工(gong)程(cheng)中應用(yong)非常廣泛，有多(duo)種(zhong)形式(shi)(shi)，主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)...
機械(xie)密封是(shi)靠彈性元件(繃簧、波紋管等) 和(he)密封液體壓力在相對運(yun)動(dong)的動(dong)環和(he)靜環的接觸面(mian)(mian)(端面(mian)(mian))上發作一(yi)恰當的壓緊力(比(bi)壓)使兩個亮光、 平直的端面(mian)(mian)緊密貼合；端面(mian)(mian)間...
機(ji)械密(mi)(mi)封(feng)(feng)(feng)是一種依靠彈性元件(jian)對動(dong)、靜環端面密(mi)(mi)封(feng)(feng)(feng)副(fu)的(de)預緊(jin)和介質壓(ya)力與彈性元件(jian)壓(ya)力的(de)壓(ya)緊(jin)而達到密(mi)(mi)封(feng)(feng)(feng)的(de)軸向(xiang)端面密(mi)(mi)封(feng)(feng)(feng)裝置。動(dong)環和靜環的(de)端面組成一對摩擦副(fu)，動(dong)環靠密(mi)(mi)封(feng)(feng)(feng)室(shi)中液(ye)...
熱水(shui)(shui)泵集式機(ji)械密封是指安裝運(yun)行在泵類設備中起動態密封作用(yong)的(de)裝置，避(bi)免(mian)水(shui)(shui)泵蝸殼中的(de)流體(ti)介(jie)質通過泵軸流出。由于水(shui)(shui)泵多為(wei)輸送流體(ti)介(jie)質，具有水(shui)(shui)平(ping)安裝、高轉速、高壓力、帶...
