機械密(mi)(mi)封(feng)(feng)包括壓(ya)力控制、溫(wen)度控制、流體替換(堵塞(sai))和雜(za)質去(qu)除系(xi)(xi)統。在(zai)機械密(mi)(mi)封(feng)(feng)系(xi)(xi)統中,上述系(xi)(xi)統并不同時包括在(zai)內。密(mi)(mi)封(feng)(feng)系(xi)(xi)統的(de)選(xuan)擇主(zhu)要取(qu)決于主(zhu)密(mi)(mi)封(feng)(feng)件的(de)應(ying)用(yong)范圍。例如,如...
機(ji)械(xie)密封利(li)用(yong)機(ji)械(xie)方式傳(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong),機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用(yong)非常廣泛(fan),有多種形式,主要(yao)包括皮(pi)帶傳(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)動(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)動(dong)(dong)(dong)和(he)螺旋傳(chuan)動(dong)(dong)(dong)...
機械密封是靠彈(dan)性元件(繃簧、波紋管等) 和密封液體壓(ya)力(li)在(zai)相對運動的動環(huan)和靜環(huan)的接觸面(mian)(端(duan)面(mian))上發作一(yi)恰當的壓(ya)緊力(li)(比壓(ya))使(shi)兩(liang)個(ge)亮光、 平(ping)直(zhi)的端(duan)面(mian)緊密貼合;端(duan)面(mian)間...
機械密(mi)封(feng)(feng)是一種依靠彈性(xing)元(yuan)件(jian)對動(dong)、靜環端面密(mi)封(feng)(feng)副的預緊(jin)和介質壓(ya)力與彈性(xing)元(yuan)件(jian)壓(ya)力的壓(ya)緊(jin)而達到密(mi)封(feng)(feng)的軸向端面密(mi)封(feng)(feng)裝置。動(dong)環和靜環的端面組(zu)成一對摩擦副,動(dong)環靠密(mi)封(feng)(feng)室中液(ye)...
熱(re)水泵(beng)集式機械(xie)密(mi)封是(shi)指安(an)裝運行在泵(beng)類設(she)備中(zhong)起動態密(mi)封作(zuo)用的裝置,避免水泵(beng)蝸殼中(zhong)的流體介質通過泵(beng)軸流出。由于水泵(beng)多為(wei)輸送(song)流體介質,具有水平安(an)裝、高轉速、高壓力、帶...
