機械密(mi)封(feng)包括壓(ya)力(li)控(kong)(kong)制、溫度控(kong)(kong)制、流體(ti)替換(堵塞)和雜質去除系(xi)(xi)統(tong)。在機械密(mi)封(feng)系(xi)(xi)統(tong)中，上述(shu)系(xi)(xi)統(tong)并不同時包括在內。密(mi)封(feng)系(xi)(xi)統(tong)的選(xuan)擇(ze)主(zhu)要取決于(yu)主(zhu)密(mi)封(feng)件的應(ying)用范圍。例如，如...
機械(xie)密封利用機械(xie)方式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在(zai)機械(xie)工程中應用非(fei)常廣泛(fan)，有多種(zhong)形式，主要包括皮帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)...
機械密(mi)封是靠彈(dan)性元(yuan)件(繃簧、波紋管(guan)等) 和密(mi)封液體(ti)壓(ya)力(li)在相對運動的(de)動環和靜(jing)環的(de)接觸面(端(duan)(duan)面)上發作一恰當的(de)壓(ya)緊力(li)(比壓(ya))使(shi)兩個亮光、 平直的(de)端(duan)(duan)面緊密(mi)貼合(he)；端(duan)(duan)面間(jian)...
機械(xie)密封(feng)(feng)是一種依靠(kao)(kao)彈(dan)性(xing)元件對動、靜(jing)環端面(mian)密封(feng)(feng)副的預緊和介質(zhi)壓力(li)與彈(dan)性(xing)元件壓力(li)的壓緊而達到密封(feng)(feng)的軸向端面(mian)密封(feng)(feng)裝置。動環和靜(jing)環的端面(mian)組成一對摩(mo)擦(ca)副，動環靠(kao)(kao)密封(feng)(feng)室中液...
熱水(shui)(shui)(shui)泵(beng)(beng)集(ji)式機械(xie)密封是指安(an)裝運(yun)行在泵(beng)(beng)類設備中(zhong)起動態(tai)密封作用的裝置，避(bi)免水(shui)(shui)(shui)泵(beng)(beng)蝸(gua)殼中(zhong)的流(liu)(liu)體(ti)介質(zhi)通過泵(beng)(beng)軸流(liu)(liu)出。由于水(shui)(shui)(shui)泵(beng)(beng)多(duo)為輸送(song)流(liu)(liu)體(ti)介質(zhi)，具有(you)水(shui)(shui)(shui)平安(an)裝、高轉速、高壓力、帶...
反(fan)壓狀態是(shi)不(bu)良(liang)的(de)工作狀態，介質(zhi)中的(de)顆粒、雜質(zhi)很容易進入密封(feng)面，使(shi)密封(feng)失效。磨軸的(de)主要件為(wei)橡膠波(bo)紋管，且由于上端(duan)密封(feng)面處于不(bu)良(liang)潤滑狀態，動靜環之間(jian)的(de)摩(mo)擦力(li)矩大于橡...
