防爆電加熱器概述
防爆電(dian)加(jia)(jia)熱器是一種國際流行的高品質(zhi)長壽命電(dian)加(jia)(jia)熱設(she)備。用于對流動的液態、氣態介質(zhi)的升溫、保溫、加(jia)(jia)熱。當加(jia)(jia)熱介質(zhi)在壓(ya)力作用下(xia)通過電(dian)加(jia)(jia)熱器加(jia)(jia)熱腔,采用流體熱力學原理均勻地帶(dai)走電(dian)熱元件工(gong)作中所產(chan)生的巨(ju)大熱量,使(shi)被(bei)加(jia)(jia)熱介質(zhi)溫度達到用戶工(gong)藝要求。
防(fang)爆電(dian)加(jia)熱器工作原理
防爆電(dian)(dian)加(jia)(jia)熱(re)(re)器(qi)(qi)是一種消耗(hao)電(dian)(dian)能(neng)轉(zhuan)換(huan)為熱(re)(re)能(neng),來對(dui)需加(jia)(jia)熱(re)(re)物料(liao)(liao)進(jin)行加(jia)(jia)熱(re)(re)。在工作中(zhong)低溫流(liu)(liu)體介(jie)(jie)質(zhi)(zhi)通過管道在壓力(li)作用(yong)下進(jin)入其(qi)輸(shu)入口,沿(yan)著電(dian)(dian)加(jia)(jia)熱(re)(re)容器(qi)(qi)內(nei)部(bu)特定換(huan)熱(re)(re)流(liu)(liu)道,運用(yong)流(liu)(liu)體熱(re)(re)力(li)學(xue)原理設計的(de)(de)路徑(jing),帶走電(dian)(dian)熱(re)(re)元件(jian)工作中(zhong)所產生的(de)(de)高溫熱(re)(re)能(neng)量,使(shi)被加(jia)(jia)熱(re)(re)介(jie)(jie)質(zhi)(zhi)溫度(du)升(sheng)高,電(dian)(dian)加(jia)(jia)熱(re)(re)器(qi)(qi)出(chu)(chu)口得到工藝要求的(de)(de)高溫介(jie)(jie)質(zhi)(zhi)。電(dian)(dian)加(jia)(jia)熱(re)(re)器(qi)(qi)內(nei)部(bu)控制(zhi)系統依據輸(shu)出(chu)(chu)口的(de)(de)溫度(du)傳感器(qi)(qi)信號自動調節電(dian)(dian)加(jia)(jia)熱(re)(re)器(qi)(qi)輸(shu)出(chu)(chu)功率,使(shi)輸(shu)出(chu)(chu)口的(de)(de)介(jie)(jie)質(zhi)(zhi)溫度(du)均勻;當發熱(re)(re)元件(jian)超(chao)溫時(shi),發熱(re)(re)元件(jian)的(de)(de)獨(du)立(li)的(de)(de)過熱(re)(re)保護裝置立(li)即(ji)切斷加(jia)(jia)熱(re)(re)電(dian)(dian)源,避免加(jia)(jia)熱(re)(re)物料(liao)(liao)超(chao)溫引起結焦、變質(zhi)(zhi)、碳化(hua),嚴重時(shi)導(dao)致(zhi)發熱(re)(re)元件(jian)燒壞(huai),有效(xiao)延長電(dian)(dian)加(jia)(jia)熱(re)(re)器(qi)(qi)使(shi)用(yong)壽命(ming)。
