法蘭(lan)加熱(re)管(guan)(也稱插(cha)入式(shi)電(dian)(dian)(dian)(dian)加熱(re)器):是采(cai)用U型管(guan)狀電(dian)(dian)(dian)(dian)熱(re)元(yuan)件(jian)(jian)，依據(ju)加熱(re)不同介(jie)(jie)質(zhi)(zhi)設計規范(fan)，按照(zhao)功(gong)率配置要求裝配在法蘭(lan)蓋上，插(cha)入需加熱(re)物料中，發(fa)(fa)熱(re)元(yuan)件(jian)(jian)工(gong)作時(shi)所(suo)發(fa)(fa)出的大(da)量熱(re)量傳導給被加熱(re)介(jie)(jie)質(zhi)(zhi)使介(jie)(jie)質(zhi)(zhi)溫(wen)度(du)升(sheng)高，達(da)到所(suo)需的工(gong)藝(yi)要求。當(dang)介(jie)(jie)質(zhi)(zhi)溫(wen)度(du)達(da)到工(gong)藝(yi)要求的設定值時(shi)控制系統根據(ju)溫(wen)度(du)傳感(gan)器信號(hao)，經PID運算后調節電(dian)(dian)(dian)(dian)加熱(re)器輸出功(gong)率，對發(fa)(fa)熱(re)元(yuan)件(jian)(jian)的電(dian)(dian)(dian)(dian)阻性負載(zai)實(shi)現溫(wen)度(du)控制。使介(jie)(jie)質(zhi)(zhi)溫(wen)度(du)均勻，達(da)到所(suo)需要求;當(dang)發(fa)(fa)熱(re)元(yuan)件(jian)(jian)超溫(wen)或低液(ye)位時(shi)，發(fa)(fa)熱(re)元(yuan)件(jian)(jian)的聯鎖保護裝置立即切斷加熱(re)電(dian)(dian)(dian)(dian)源避(bi)免發(fa)(fa)熱(re)元(yuan)件(jian)(jian)燒壞，延長使用壽命。

產品特點

法蘭加熱(re)管(guan)(guan)表(biao)面功率大，是空氣加熱(re)表(biao)面負(fu)荷的(de)2~4倍高(gao)度密(mi)(mi)(mi)集式、結(jie)構緊(jin)(jin)湊。由于整體(ti)短(duan)而密(mi)(mi)(mi)集，故穩(wen)定性好，安裝無需支架(jia)組合式大多(duo)采(cai)用(yong)(yong)氬弧(hu)焊接(jie)方(fang)式使電熱(re)管(guan)(guan)于法蘭連接(jie)，也(ye)可利用(yong)(yong)緊(jin)(jin)固(gu)(gu)裝置的(de)形(xing)式，即每支電熱(re)管(guan)(guan)上(shang)焊由緊(jin)(jin)固(gu)(gu)件(jian)。然后與法蘭蓋采(cai)用(yong)(yong)螺母鎖緊(jin)(jin)。管(guan)(guan)子于緊(jin)(jin)固(gu)(gu)件(jian)采(cai)用(yong)(yong)氬弧(hu)焊接(jie)，緊(jin)(jin)固(gu)(gu)件(jian)密(mi)(mi)(mi)封(feng)處采(cai)用(yong)(yong)科學的(de)工藝。單支更換方(fang)便，節(jie)約以(yi)后的(de)維修成(cheng)本。
