防爆電加熱器概述
防爆電加熱(re)(re)器是一種(zhong)國際(ji)流行的(de)高品質(zhi)長壽命電加熱(re)(re)設備。用于對流動的(de)液態、氣態介質(zhi)的(de)升溫(wen)、保溫(wen)、加熱(re)(re)。當加熱(re)(re)介質(zhi)在壓(ya)力(li)作(zuo)用下通(tong)過電加熱(re)(re)器加熱(re)(re)腔,采用流體熱(re)(re)力(li)學原理均(jun)勻地(di)帶走電熱(re)(re)元件工作(zuo)中所產生的(de)巨大熱(re)(re)量(liang),使(shi)被加熱(re)(re)介質(zhi)溫(wen)度達到(dao)用戶工藝要(yao)求。
防爆(bao)電加(jia)熱器工作(zuo)原(yuan)理
防爆電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器是一種消耗電(dian)(dian)能(neng)轉換為熱(re)(re)(re)能(neng),來對需加(jia)(jia)(jia)熱(re)(re)(re)物料進行加(jia)(jia)(jia)熱(re)(re)(re)。在工(gong)作中低溫(wen)(wen)(wen)(wen)流體介質(zhi)(zhi)(zhi)(zhi)通(tong)過管道(dao)在壓力作用(yong)下進入其(qi)輸(shu)入口,沿著電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)容器內部特(te)定(ding)換熱(re)(re)(re)流道(dao),運用(yong)流體熱(re)(re)(re)力學原理設計的(de)(de)路徑(jing),帶走電(dian)(dian)熱(re)(re)(re)元件工(gong)作中所產(chan)生(sheng)的(de)(de)高溫(wen)(wen)(wen)(wen)熱(re)(re)(re)能(neng)量,使(shi)被加(jia)(jia)(jia)熱(re)(re)(re)介質(zhi)(zhi)(zhi)(zhi)溫(wen)(wen)(wen)(wen)度升高,電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器出(chu)(chu)口得到工(gong)藝要求的(de)(de)高溫(wen)(wen)(wen)(wen)介質(zhi)(zhi)(zhi)(zhi)。電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器內部控制系(xi)統依(yi)據輸(shu)出(chu)(chu)口的(de)(de)溫(wen)(wen)(wen)(wen)度傳(chuan)感器信號自動(dong)調節電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器輸(shu)出(chu)(chu)功率,使(shi)輸(shu)出(chu)(chu)口的(de)(de)介質(zhi)(zhi)(zhi)(zhi)溫(wen)(wen)(wen)(wen)度均勻;當(dang)發熱(re)(re)(re)元件超溫(wen)(wen)(wen)(wen)時,發熱(re)(re)(re)元件的(de)(de)獨立的(de)(de)過熱(re)(re)(re)保(bao)護(hu)裝置立即切斷(duan)加(jia)(jia)(jia)熱(re)(re)(re)電(dian)(dian)源(yuan),避免加(jia)(jia)(jia)熱(re)(re)(re)物料超溫(wen)(wen)(wen)(wen)引起結焦、變(bian)質(zhi)(zhi)(zhi)(zhi)、碳(tan)化(hua),嚴(yan)重時導致發熱(re)(re)(re)元件燒壞,有效延長電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器使(shi)用(yong)壽命。
