機械密(mi)封包括壓力控制(zhi)、溫(wen)度(du)控制(zhi)、流體替換(堵塞(sai))和雜(za)質去除系(xi)(xi)統(tong)。在機械密(mi)封系(xi)(xi)統(tong)中，上述(shu)系(xi)(xi)統(tong)并不(bu)同(tong)時(shi)包括在內。密(mi)封系(xi)(xi)統(tong)的選(xuan)擇主(zhu)要取決于(yu)主(zhu)密(mi)封件(jian)的應用范(fan)圍。例(li)如，如...
機械(xie)(xie)密封利用機械(xie)(xie)方(fang)式傳(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)，機械(xie)(xie)傳(chuan)動(dong)(dong)(dong)在(zai)機械(xie)(xie)工程中應用非常廣(guang)泛，有多種形(xing)式，主要包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)動(dong)(dong)(dong)和螺(luo)旋傳(chuan)動(dong)(dong)(dong)...
機械密封(feng)是靠彈性元(yuan)件(繃簧、波紋(wen)管(guan)等(deng)) 和密封(feng)液體壓力在相對運(yun)動(dong)的動(dong)環和靜環的接觸面(mian)(端面(mian))上發作一恰當的壓緊力(比壓)使兩(liang)個(ge)亮光、 平直的端面(mian)緊密貼合；端面(mian)間(jian)...
機械密封(feng)是一種依靠(kao)彈性元件(jian)對(dui)動(dong)、靜環(huan)(huan)端(duan)面(mian)密封(feng)副的預(yu)緊(jin)(jin)和(he)(he)介質(zhi)壓力與彈性元件(jian)壓力的壓緊(jin)(jin)而達到密封(feng)的軸向端(duan)面(mian)密封(feng)裝置(zhi)。動(dong)環(huan)(huan)和(he)(he)靜環(huan)(huan)的端(duan)面(mian)組(zu)成一對(dui)摩擦(ca)副，動(dong)環(huan)(huan)靠(kao)密封(feng)室(shi)中液...
熱水(shui)泵集(ji)式機械密封是(shi)指安(an)裝運行在泵類(lei)設備(bei)中起動態(tai)密封作用的(de)裝置，避免(mian)水(shui)泵蝸殼中的(de)流(liu)體介質通過泵軸流(liu)出(chu)。由于水(shui)泵多為輸送流(liu)體介質，具有水(shui)平安(an)裝、高轉速、高壓力、帶...
反壓狀(zhuang)態(tai)是不良的工(gong)作(zuo)狀(zhuang)態(tai)，介質中的顆粒、雜(za)質很(hen)容(rong)易進入(ru)密(mi)封面，使(shi)密(mi)封失效。磨(mo)軸(zhou)的主(zhu)要件為橡膠波紋管，且由于(yu)上端密(mi)封面處于(yu)不良潤滑狀(zhuang)態(tai)，動靜(jing)環之間的摩擦力矩大于(yu)橡...
