防爆電加熱器概述 

防(fang)爆電(dian)(dian)加(jia)(jia)熱器是一種國際流行的高品質長壽命電(dian)(dian)加(jia)(jia)熱設備(bei)。用(yong)(yong)于對流動的液態、氣態介(jie)(jie)質的升(sheng)溫(wen)、保(bao)溫(wen)、加(jia)(jia)熱。當加(jia)(jia)熱介(jie)(jie)質在(zai)壓(ya)力(li)(li)作(zuo)用(yong)(yong)下通過電(dian)(dian)加(jia)(jia)熱器加(jia)(jia)熱腔(qiang)，采用(yong)(yong)流體熱力(li)(li)學(xue)原理均勻地帶走電(dian)(dian)熱元(yuan)件工作(zuo)中所產生的巨(ju)大熱量(liang)，使被加(jia)(jia)熱介(jie)(jie)質溫(wen)度達到用(yong)(yong)戶(hu)工藝要求。

防爆電加(jia)熱(re)器工作(zuo)原(yuan)理 

防爆(bao)電(dian)加熱(re)(re)(re)(re)(re)器(qi)是(shi)一種消耗電(dian)能(neng)(neng)轉換為熱(re)(re)(re)(re)(re)能(neng)(neng)，來對需加熱(re)(re)(re)(re)(re)物料進(jin)行加熱(re)(re)(re)(re)(re)。在(zai)工(gong)作(zuo)中低溫流(liu)(liu)體介質(zhi)(zhi)(zhi)通過(guo)管道在(zai)壓力作(zuo)用(yong)下進(jin)入(ru)其輸入(ru)口，沿著電(dian)加熱(re)(re)(re)(re)(re)容器(qi)內部(bu)特定換熱(re)(re)(re)(re)(re)流(liu)(liu)道，運用(yong)流(liu)(liu)體熱(re)(re)(re)(re)(re)力學(xue)原(yuan)理(li)設計的路徑(jing)，帶走(zou)電(dian)熱(re)(re)(re)(re)(re)元件(jian)工(gong)作(zuo)中所(suo)產生的高溫熱(re)(re)(re)(re)(re)能(neng)(neng)量，使(shi)(shi)(shi)被加熱(re)(re)(re)(re)(re)介質(zhi)(zhi)(zhi)溫度升(sheng)高，電(dian)加熱(re)(re)(re)(re)(re)器(qi)出口得到工(gong)藝(yi)要(yao)求的高溫介質(zhi)(zhi)(zhi)。電(dian)加熱(re)(re)(re)(re)(re)器(qi)內部(bu)控制系統(tong)依(yi)據(ju)輸出口的溫度傳感(gan)器(qi)信號自動調節(jie)電(dian)加熱(re)(re)(re)(re)(re)器(qi)輸出功率，使(shi)(shi)(shi)輸出口的介質(zhi)(zhi)(zhi)溫度均勻；當發熱(re)(re)(re)(re)(re)元件(jian)超溫時，發熱(re)(re)(re)(re)(re)元件(jian)的獨立的過(guo)熱(re)(re)(re)(re)(re)保護裝置立即(ji)切斷加熱(re)(re)(re)(re)(re)電(dian)源(yuan)，避(bi)免加熱(re)(re)(re)(re)(re)物料超溫引起結(jie)焦、變質(zhi)(zhi)(zhi)、碳化，嚴重時導致發熱(re)(re)(re)(re)(re)元件(jian)燒壞，有效延(yan)長電(dian)加熱(re)(re)(re)(re)(re)器(qi)使(shi)(shi)(shi)用(yong)壽命。
