法蘭式電(dian)(dian)加(jia)熱(re)管是采用U型管狀電(dian)(dian)熱(re)元(yuan)件(jian)，依據加(jia)熱(re)不同介(jie)(jie)質(zhi)(zhi)設計(ji)規范(fan)，按照功(gong)(gong)率配(pei)(pei)置要(yao)求(qiu)裝(zhuang)配(pei)(pei)在法蘭蓋上(shang)，插入需(xu)加(jia)熱(re)物料中，發(fa)熱(re)元(yuan)件(jian)工作(zuo)時(shi)(shi)所發(fa)出的大量熱(re)量傳導給被加(jia)熱(re)介(jie)(jie)質(zhi)(zhi)使介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)(wen)(wen)(wen)度(du)升高，達到(dao)所需(xu)的工藝(yi)要(yao)求(qiu)。當介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)(wen)(wen)(wen)度(du)達到(dao)工藝(yi)要(yao)求(qiu)的設定值(zhi)時(shi)(shi)控制系統根據溫(wen)(wen)(wen)(wen)(wen)度(du)傳感器信號，經PID運算(suan)后調節(jie)電(dian)(dian)加(jia)熱(re)器輸出功(gong)(gong)率，對發(fa)熱(re)元(yuan)件(jian)的電(dian)(dian)阻(zu)性(xing)負(fu)載實現溫(wen)(wen)(wen)(wen)(wen)度(du)控制。使介(jie)(jie)質(zhi)(zhi)溫(wen)(wen)(wen)(wen)(wen)度(du)均勻，達到(dao)所需(xu)要(yao)求(qiu);當發(fa)熱(re)元(yuan)件(jian)超(chao)溫(wen)(wen)(wen)(wen)(wen)或低液位時(shi)(shi)，發(fa)熱(re)元(yuan)件(jian)的聯鎖保護裝(zhuang)置立即切斷(duan)加(jia)熱(re)電(dian)(dian)源避免發(fa)熱(re)元(yuan)件(jian)燒壞，延長使用壽命。

產品特點

法(fa)蘭式電加熱管(guan)表面功率大，是空氣加熱表面負荷(he)的2~4倍高度密(mi)(mi)集(ji)式、結構緊湊。由于整(zheng)體(ti)短而密(mi)(mi)集(ji)，故穩定性好，安(an)裝無(wu)需支(zhi)(zhi)架組合(he)式大多采(cai)用氬(ya)弧(hu)焊(han)(han)(han)接方式使電熱管(guan)于法(fa)蘭連接，也可利(li)用緊固(gu)(gu)裝置的形式，即每支(zhi)(zhi)電熱管(guan)上焊(han)(han)(han)由緊固(gu)(gu)件(jian)。然后(hou)與法(fa)蘭蓋采(cai)用螺母鎖緊。管(guan)子于緊固(gu)(gu)件(jian)采(cai)用氬(ya)弧(hu)焊(han)(han)(han)接，緊固(gu)(gu)件(jian)密(mi)(mi)封處(chu)采(cai)用科學的工藝。單支(zhi)(zhi)更換方便(bian)，節(jie)約以后(hou)的維修成(cheng)本(ben)。
