法蘭式(shi)電(dian)加(jia)熱(re)(re)(re)(re)管(guan)是采(cai)用(yong)U型(xing)管(guan)狀電(dian)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)(jian)(jian)，依據加(jia)熱(re)(re)(re)(re)不(bu)同介質(zhi)設計規范，按照功率配置要求裝配在法蘭蓋上，插入需(xu)加(jia)熱(re)(re)(re)(re)物(wu)料中，發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)(jian)(jian)工(gong)作時所發(fa)出(chu)的大量熱(re)(re)(re)(re)量傳導給被加(jia)熱(re)(re)(re)(re)介質(zhi)使(shi)(shi)介質(zhi)溫度(du)升(sheng)高(gao)，達到所需(xu)的工(gong)藝要求。當(dang)介質(zhi)溫度(du)達到工(gong)藝要求的設定(ding)值時控制系統根據溫度(du)傳感器信號，經PID運算后(hou)調(diao)節電(dian)加(jia)熱(re)(re)(re)(re)器輸(shu)出(chu)功率，對發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)(jian)(jian)的電(dian)阻性負載實現(xian)溫度(du)控制。使(shi)(shi)介質(zhi)溫度(du)均勻，達到所需(xu)要求;當(dang)發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)(jian)(jian)超溫或(huo)低液位(wei)時，發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)(jian)(jian)的聯鎖保護裝置立即切斷加(jia)熱(re)(re)(re)(re)電(dian)源(yuan)避免發(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)(jian)(jian)燒壞，延長使(shi)(shi)用(yong)壽命(ming)。

產品特點

法蘭式(shi)電(dian)加熱(re)管(guan)(guan)(guan)表面功率大，是空氣加熱(re)表面負荷(he)的(de)2~4倍高(gao)度密集式(shi)、結(jie)構緊湊(cou)。由于(yu)整體短(duan)而密集，故穩定性好(hao)，安裝無需支(zhi)架(jia)組合式(shi)大多采用氬弧(hu)焊接方式(shi)使(shi)電(dian)熱(re)管(guan)(guan)(guan)于(yu)法蘭連接，也可利(li)用緊固(gu)裝置的(de)形式(shi)，即每支(zhi)電(dian)熱(re)管(guan)(guan)(guan)上焊由緊固(gu)件。然(ran)后與法蘭蓋采用螺母鎖緊。管(guan)(guan)(guan)子于(yu)緊固(gu)件采用氬弧(hu)焊接，緊固(gu)件密封(feng)處采用科學的(de)工藝。單支(zhi)更(geng)換(huan)方便，節約以后的(de)維修(xiu)成本。
