法蘭加熱(re)(re)(re)管(也稱插(cha)(cha)入式電(dian)加熱(re)(re)(re)器):是(shi)采(cai)用(yong)U型管狀電(dian)熱(re)(re)(re)元(yuan)件(jian)(jian)，依據加熱(re)(re)(re)不同介質(zhi)設計規范，按照功率(lv)配置(zhi)(zhi)要(yao)(yao)求(qiu)(qiu)裝配在法蘭蓋上(shang)，插(cha)(cha)入需加熱(re)(re)(re)物料中，發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)工(gong)作時(shi)(shi)所(suo)發(fa)(fa)出的大(da)量熱(re)(re)(re)量傳導(dao)給被(bei)加熱(re)(re)(re)介質(zhi)使介質(zhi)溫(wen)(wen)度升(sheng)高，達(da)到(dao)所(suo)需的工(gong)藝要(yao)(yao)求(qiu)(qiu)。當介質(zhi)溫(wen)(wen)度達(da)到(dao)工(gong)藝要(yao)(yao)求(qiu)(qiu)的設定值(zhi)時(shi)(shi)控(kong)制系統根(gen)據溫(wen)(wen)度傳感器信號，經PID運算后調節電(dian)加熱(re)(re)(re)器輸出功率(lv)，對發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)的電(dian)阻性負載實現溫(wen)(wen)度控(kong)制。使介質(zhi)溫(wen)(wen)度均勻，達(da)到(dao)所(suo)需要(yao)(yao)求(qiu)(qiu);當發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)超溫(wen)(wen)或低液位時(shi)(shi)，發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)的聯鎖保護裝置(zhi)(zhi)立即切(qie)斷加熱(re)(re)(re)電(dian)源避免發(fa)(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)燒壞，延長使用(yong)壽命。

產品特點

法蘭加熱管(guan)(guan)表面功率大，是空氣加熱表面負荷的(de)2~4倍高度(du)密集式、結(jie)構緊湊。由于整體(ti)短而(er)密集，故(gu)穩(wen)定性好(hao)，安(an)裝(zhuang)無需支(zhi)架組合式大多采用(yong)氬弧(hu)焊(han)接(jie)方式使電熱管(guan)(guan)于法蘭連(lian)接(jie)，也(ye)可利用(yong)緊固(gu)裝(zhuang)置的(de)形式，即(ji)每支(zhi)電熱管(guan)(guan)上焊(han)由緊固(gu)件。然后與法蘭蓋采用(yong)螺母鎖緊。管(guan)(guan)子于緊固(gu)件采用(yong)氬弧(hu)焊(han)接(jie)，緊固(gu)件密封處(chu)采用(yong)科學的(de)工藝。單支(zhi)更(geng)換方便(bian)，節(jie)約以后的(de)維(wei)修成本。
