防爆電加熱器概述
防爆電加(jia)熱(re)(re)器是(shi)一種國(guo)際流(liu)行的(de)(de)高品(pin)質(zhi)長壽命電加(jia)熱(re)(re)設備。用于對(dui)流(liu)動的(de)(de)液態(tai)(tai)、氣態(tai)(tai)介(jie)質(zhi)的(de)(de)升溫、保溫、加(jia)熱(re)(re)。當加(jia)熱(re)(re)介(jie)質(zhi)在壓力作(zuo)用下(xia)通過電加(jia)熱(re)(re)器加(jia)熱(re)(re)腔,采用流(liu)體(ti)熱(re)(re)力學(xue)原理均勻(yun)地帶走電熱(re)(re)元件工作(zuo)中所產(chan)生的(de)(de)巨大熱(re)(re)量,使被加(jia)熱(re)(re)介(jie)質(zhi)溫度(du)達到用戶(hu)工藝要求。
防爆電加熱器工作(zuo)原理
防爆電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)是一(yi)種消(xiao)耗電(dian)(dian)(dian)(dian)(dian)能(neng)轉換為熱(re)(re)(re)(re)能(neng),來對需加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)物料進(jin)行加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)。在工(gong)作中低溫(wen)流體(ti)介質(zhi)(zhi)通(tong)過(guo)管(guan)道在壓力(li)作用(yong)下進(jin)入其輸(shu)(shu)入口,沿著電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)容(rong)器(qi)內部特定(ding)換熱(re)(re)(re)(re)流道,運用(yong)流體(ti)熱(re)(re)(re)(re)力(li)學原理設計的(de)(de)(de)路徑(jing),帶走(zou)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)元(yuan)件(jian)工(gong)作中所產生的(de)(de)(de)高(gao)溫(wen)熱(re)(re)(re)(re)能(neng)量,使(shi)被加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)介質(zhi)(zhi)溫(wen)度(du)升高(gao),電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)出(chu)口得(de)到(dao)工(gong)藝要求(qiu)的(de)(de)(de)高(gao)溫(wen)介質(zhi)(zhi)。電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)內部控(kong)制系統(tong)依據(ju)輸(shu)(shu)出(chu)口的(de)(de)(de)溫(wen)度(du)傳感器(qi)信號自動調(diao)節電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)輸(shu)(shu)出(chu)功率,使(shi)輸(shu)(shu)出(chu)口的(de)(de)(de)介質(zhi)(zhi)溫(wen)度(du)均勻;當發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)超(chao)溫(wen)時(shi),發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)的(de)(de)(de)獨立的(de)(de)(de)過(guo)熱(re)(re)(re)(re)保(bao)護(hu)裝(zhuang)置立即(ji)切斷加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)源,避免加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)物料超(chao)溫(wen)引起結焦、變質(zhi)(zhi)、碳化,嚴重時(shi)導(dao)致發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)燒壞,有效延長(chang)電(dian)(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)使(shi)用(yong)壽命(ming)。
