法蘭式電(dian)加熱(re)(re)(re)(re)管是(shi)采用(yong)U型(xing)管狀電(dian)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)，依據加熱(re)(re)(re)(re)不(bu)同介質(zhi)設計規范，按照功(gong)率配(pei)(pei)置要求裝配(pei)(pei)在法蘭蓋(gai)上，插入需(xu)加熱(re)(re)(re)(re)物料(liao)中(zhong)，發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)工(gong)作時(shi)所(suo)發(fa)出的大量熱(re)(re)(re)(re)量傳導給被加熱(re)(re)(re)(re)介質(zhi)使介質(zhi)溫(wen)(wen)度升高(gao)，達(da)到(dao)所(suo)需(xu)的工(gong)藝要求。當介質(zhi)溫(wen)(wen)度達(da)到(dao)工(gong)藝要求的設定值(zhi)時(shi)控制(zhi)系統(tong)根據溫(wen)(wen)度傳感器(qi)信號(hao)，經(jing)PID運(yun)算后調節電(dian)加熱(re)(re)(re)(re)器(qi)輸出功(gong)率，對發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的電(dian)阻(zu)性(xing)負載實現溫(wen)(wen)度控制(zhi)。使介質(zhi)溫(wen)(wen)度均勻，達(da)到(dao)所(suo)需(xu)要求;當發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)(wen)或低液位時(shi)，發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的聯鎖保護裝置立即(ji)切斷(duan)加熱(re)(re)(re)(re)電(dian)源避免發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)燒壞，延(yan)長使用(yong)壽命。

產品特點

法(fa)蘭(lan)式電加熱(re)(re)管表(biao)面(mian)功率大(da)(da)，是(shi)空氣加熱(re)(re)表(biao)面(mian)負荷的2~4倍高度密集(ji)式、結構緊(jin)(jin)(jin)湊。由于整體短而密集(ji)，故(gu)穩定性好，安裝(zhuang)無需(xu)支(zhi)架(jia)組合式大(da)(da)多采用(yong)(yong)氬(ya)弧(hu)焊(han)接方式使電熱(re)(re)管于法(fa)蘭(lan)連接，也(ye)可利用(yong)(yong)緊(jin)(jin)(jin)固(gu)(gu)裝(zhuang)置的形式，即每支(zhi)電熱(re)(re)管上焊(han)由緊(jin)(jin)(jin)固(gu)(gu)件(jian)。然后(hou)與法(fa)蘭(lan)蓋采用(yong)(yong)螺(luo)母鎖緊(jin)(jin)(jin)。管子(zi)于緊(jin)(jin)(jin)固(gu)(gu)件(jian)采用(yong)(yong)氬(ya)弧(hu)焊(han)接，緊(jin)(jin)(jin)固(gu)(gu)件(jian)密封處(chu)采用(yong)(yong)科學(xue)的工藝(yi)。單(dan)支(zhi)更換方便，節約以后(hou)的維修成本。
