防爆電加熱器概述
防(fang)爆電(dian)(dian)加熱(re)(re)器是一種國際流行(xing)的高品質長壽(shou)命電(dian)(dian)加熱(re)(re)設(she)備。用(yong)于對流動的液態(tai)、氣(qi)態(tai)介質的升溫、保溫、加熱(re)(re)。當(dang)加熱(re)(re)介質在(zai)壓力作用(yong)下通過電(dian)(dian)加熱(re)(re)器加熱(re)(re)腔,采(cai)用(yong)流體熱(re)(re)力學原理(li)均(jun)勻地帶走電(dian)(dian)熱(re)(re)元件(jian)工(gong)作中所產(chan)生的巨(ju)大熱(re)(re)量(liang),使(shi)被加熱(re)(re)介質溫度達到(dao)用(yong)戶工(gong)藝要求。
防爆電加熱器(qi)工(gong)作原理(li)
防爆電(dian)加熱(re)(re)器是(shi)一種消(xiao)耗電(dian)能轉換為熱(re)(re)能,來(lai)對需(xu)加熱(re)(re)物(wu)料進行加熱(re)(re)。在(zai)工(gong)作(zuo)(zuo)中低(di)溫(wen)(wen)流(liu)(liu)體介質(zhi)(zhi)通過管(guan)道在(zai)壓力作(zuo)(zuo)用(yong)下進入其輸入口(kou),沿著電(dian)加熱(re)(re)容器內(nei)(nei)部(bu)特定換熱(re)(re)流(liu)(liu)道,運用(yong)流(liu)(liu)體熱(re)(re)力學原理設計的(de)路徑,帶走電(dian)熱(re)(re)元件(jian)工(gong)作(zuo)(zuo)中所產生的(de)高(gao)溫(wen)(wen)熱(re)(re)能量,使被加熱(re)(re)介質(zhi)(zhi)溫(wen)(wen)度升高(gao),電(dian)加熱(re)(re)器出(chu)口(kou)得到(dao)工(gong)藝要求的(de)高(gao)溫(wen)(wen)介質(zhi)(zhi)。電(dian)加熱(re)(re)器內(nei)(nei)部(bu)控制系統依據輸出(chu)口(kou)的(de)溫(wen)(wen)度傳感器信號自動調節電(dian)加熱(re)(re)器輸出(chu)功率,使輸出(chu)口(kou)的(de)介質(zhi)(zhi)溫(wen)(wen)度均(jun)勻;當發(fa)熱(re)(re)元件(jian)超溫(wen)(wen)時,發(fa)熱(re)(re)元件(jian)的(de)獨(du)立的(de)過熱(re)(re)保護裝置立即切斷加熱(re)(re)電(dian)源,避免(mian)加熱(re)(re)物(wu)料超溫(wen)(wen)引起(qi)結焦、變質(zhi)(zhi)、碳化,嚴重時導致發(fa)熱(re)(re)元件(jian)燒(shao)壞(huai),有效延長電(dian)加熱(re)(re)器使用(yong)壽命。
