防爆電加熱器概述
防爆電加(jia)(jia)熱(re)(re)器是(shi)一種國(guo)際流(liu)行的(de)高品質(zhi)長壽命電加(jia)(jia)熱(re)(re)設備。用(yong)(yong)于對流(liu)動(dong)的(de)液態、氣態介質(zhi)的(de)升(sheng)溫(wen)、保溫(wen)、加(jia)(jia)熱(re)(re)。當加(jia)(jia)熱(re)(re)介質(zhi)在壓力(li)作用(yong)(yong)下通過電加(jia)(jia)熱(re)(re)器加(jia)(jia)熱(re)(re)腔,采用(yong)(yong)流(liu)體熱(re)(re)力(li)學原理均勻地帶走(zou)電熱(re)(re)元件工作中所(suo)產生的(de)巨大熱(re)(re)量,使被(bei)加(jia)(jia)熱(re)(re)介質(zhi)溫(wen)度達到用(yong)(yong)戶工藝要求。
防(fang)爆電加熱(re)器工作原理
防爆電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器是(shi)一(yi)種消耗電(dian)(dian)能轉(zhuan)換(huan)為(wei)熱(re)(re)(re)能,來對需加(jia)(jia)(jia)熱(re)(re)(re)物料進行加(jia)(jia)(jia)熱(re)(re)(re)。在工作中(zhong)低溫(wen)(wen)流體介質(zhi)通(tong)過(guo)管(guan)道在壓(ya)力(li)作用(yong)下進入其(qi)輸(shu)入口(kou),沿著電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)容器內部特定換(huan)熱(re)(re)(re)流道,運用(yong)流體熱(re)(re)(re)力(li)學原理(li)設計的路(lu)徑,帶走電(dian)(dian)熱(re)(re)(re)元(yuan)件(jian)工作中(zhong)所(suo)產生的高(gao)溫(wen)(wen)熱(re)(re)(re)能量,使被加(jia)(jia)(jia)熱(re)(re)(re)介質(zhi)溫(wen)(wen)度(du)升高(gao),電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器出口(kou)得到工藝要求的高(gao)溫(wen)(wen)介質(zhi)。電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器內部控制系統依(yi)據輸(shu)出口(kou)的溫(wen)(wen)度(du)傳(chuan)感(gan)器信(xin)號(hao)自動調節電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器輸(shu)出功率(lv),使輸(shu)出口(kou)的介質(zhi)溫(wen)(wen)度(du)均勻(yun);當發(fa)熱(re)(re)(re)元(yuan)件(jian)超(chao)溫(wen)(wen)時,發(fa)熱(re)(re)(re)元(yuan)件(jian)的獨立(li)的過(guo)熱(re)(re)(re)保護裝置立(li)即(ji)切斷(duan)加(jia)(jia)(jia)熱(re)(re)(re)電(dian)(dian)源(yuan),避免(mian)加(jia)(jia)(jia)熱(re)(re)(re)物料超(chao)溫(wen)(wen)引起(qi)結焦(jiao)、變(bian)質(zhi)、碳(tan)化,嚴重(zhong)時導(dao)致發(fa)熱(re)(re)(re)元(yuan)件(jian)燒壞,有效延長電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)器使用(yong)壽命。
