防爆電加熱器概述
防(fang)爆電(dian)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)是一種國際流行(xing)的(de)(de)高品質長壽命電(dian)加(jia)(jia)(jia)熱(re)(re)(re)設備。用于對流動的(de)(de)液(ye)態、氣態介質的(de)(de)升溫、保溫、加(jia)(jia)(jia)熱(re)(re)(re)。當加(jia)(jia)(jia)熱(re)(re)(re)介質在壓力作用下通過電(dian)加(jia)(jia)(jia)熱(re)(re)(re)器(qi)加(jia)(jia)(jia)熱(re)(re)(re)腔(qiang),采用流體熱(re)(re)(re)力學(xue)原理均勻地帶走電(dian)熱(re)(re)(re)元件工作中所產(chan)生的(de)(de)巨大熱(re)(re)(re)量,使(shi)被加(jia)(jia)(jia)熱(re)(re)(re)介質溫度達到用戶工藝要求。
防爆電加熱器(qi)工作原(yuan)理(li)
防爆電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)是一種消耗電(dian)(dian)能(neng)轉換(huan)為熱(re)(re)(re)(re)能(neng),來(lai)對需加(jia)(jia)(jia)熱(re)(re)(re)(re)物料進行加(jia)(jia)(jia)熱(re)(re)(re)(re)。在工(gong)作中低(di)溫(wen)(wen)流(liu)(liu)體介(jie)(jie)質(zhi)(zhi)通過管道(dao)在壓力作用下進入(ru)其輸入(ru)口(kou),沿(yan)著電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)容器(qi)內部特定換(huan)熱(re)(re)(re)(re)流(liu)(liu)道(dao),運用流(liu)(liu)體熱(re)(re)(re)(re)力學(xue)原理設計的路徑,帶走電(dian)(dian)熱(re)(re)(re)(re)元件(jian)(jian)(jian)工(gong)作中所產生的高(gao)溫(wen)(wen)熱(re)(re)(re)(re)能(neng)量,使(shi)被加(jia)(jia)(jia)熱(re)(re)(re)(re)介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度升(sheng)高(gao),電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)出(chu)口(kou)得(de)到工(gong)藝(yi)要求的高(gao)溫(wen)(wen)介(jie)(jie)質(zhi)(zhi)。電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)內部控(kong)制系統依據輸出(chu)口(kou)的溫(wen)(wen)度傳感器(qi)信號(hao)自動(dong)調節(jie)電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)輸出(chu)功率,使(shi)輸出(chu)口(kou)的介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)度均勻;當發熱(re)(re)(re)(re)元件(jian)(jian)(jian)超(chao)溫(wen)(wen)時,發熱(re)(re)(re)(re)元件(jian)(jian)(jian)的獨立的過熱(re)(re)(re)(re)保護裝置立即切斷(duan)加(jia)(jia)(jia)熱(re)(re)(re)(re)電(dian)(dian)源,避免加(jia)(jia)(jia)熱(re)(re)(re)(re)物料超(chao)溫(wen)(wen)引起結焦、變質(zhi)(zhi)、碳化(hua),嚴重時導致發熱(re)(re)(re)(re)元件(jian)(jian)(jian)燒(shao)壞,有效延長(chang)電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)使(shi)用壽命。
