防爆電加熱器概述
防爆電加(jia)熱(re)(re)(re)器(qi)(qi)是一(yi)種(zhong)國際流行的(de)高品質長(chang)壽命電加(jia)熱(re)(re)(re)設備。用于(yu)對流動(dong)的(de)液態、氣態介質的(de)升溫、保溫、加(jia)熱(re)(re)(re)。當加(jia)熱(re)(re)(re)介質在壓力(li)作(zuo)用下(xia)通過電加(jia)熱(re)(re)(re)器(qi)(qi)加(jia)熱(re)(re)(re)腔,采用流體熱(re)(re)(re)力(li)學原理均勻地帶走(zou)電熱(re)(re)(re)元件工作(zuo)中所產(chan)生的(de)巨(ju)大熱(re)(re)(re)量,使被(bei)加(jia)熱(re)(re)(re)介質溫度達到用戶工藝要(yao)求(qiu)。
防爆電加熱器工(gong)作原理
防爆電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器是一種消耗電(dian)(dian)(dian)(dian)能(neng)轉換為熱(re)(re)(re)(re)能(neng),來對需(xu)加(jia)(jia)熱(re)(re)(re)(re)物料(liao)(liao)進行加(jia)(jia)熱(re)(re)(re)(re)。在工(gong)作(zuo)(zuo)中低溫(wen)(wen)(wen)流體介(jie)(jie)(jie)質(zhi)(zhi)通過(guo)管(guan)道(dao)在壓力(li)作(zuo)(zuo)用下進入(ru)其輸入(ru)口(kou),沿著電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)容器內部(bu)特定換熱(re)(re)(re)(re)流道(dao),運(yun)用流體熱(re)(re)(re)(re)力(li)學原理設計的(de)路徑,帶走電(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)工(gong)作(zuo)(zuo)中所產生的(de)高溫(wen)(wen)(wen)熱(re)(re)(re)(re)能(neng)量,使(shi)被加(jia)(jia)熱(re)(re)(re)(re)介(jie)(jie)(jie)質(zhi)(zhi)溫(wen)(wen)(wen)度升高,電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器出口(kou)得到工(gong)藝要(yao)求的(de)高溫(wen)(wen)(wen)介(jie)(jie)(jie)質(zhi)(zhi)。電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器內部(bu)控制系統依據輸出口(kou)的(de)溫(wen)(wen)(wen)度傳感器信號自(zi)動(dong)調節電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器輸出功率,使(shi)輸出口(kou)的(de)介(jie)(jie)(jie)質(zhi)(zhi)溫(wen)(wen)(wen)度均(jun)勻;當發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)超(chao)溫(wen)(wen)(wen)時(shi)(shi),發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)的(de)獨立的(de)過(guo)熱(re)(re)(re)(re)保護裝置立即切斷加(jia)(jia)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)源,避免(mian)加(jia)(jia)熱(re)(re)(re)(re)物料(liao)(liao)超(chao)溫(wen)(wen)(wen)引起結(jie)焦、變質(zhi)(zhi)、碳化,嚴(yan)重時(shi)(shi)導致發熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)燒壞,有效延長(chang)電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re)器使(shi)用壽命。
