法蘭(lan)式電(dian)加(jia)熱(re)(re)(re)管是采用U型(xing)管狀電(dian)熱(re)(re)(re)元件(jian)(jian)，依據(ju)加(jia)熱(re)(re)(re)不同介(jie)質設(she)計規范，按(an)照(zhao)功(gong)(gong)率(lv)配置要(yao)求裝配在(zai)法蘭(lan)蓋(gai)上(shang)，插(cha)入需(xu)(xu)(xu)加(jia)熱(re)(re)(re)物料中，發(fa)熱(re)(re)(re)元件(jian)(jian)工(gong)作時(shi)所發(fa)出(chu)的(de)大量熱(re)(re)(re)量傳導給被(bei)加(jia)熱(re)(re)(re)介(jie)質使(shi)介(jie)質溫(wen)(wen)度(du)升高(gao)，達(da)(da)到所需(xu)(xu)(xu)的(de)工(gong)藝要(yao)求。當介(jie)質溫(wen)(wen)度(du)達(da)(da)到工(gong)藝要(yao)求的(de)設(she)定值時(shi)控制系統根據(ju)溫(wen)(wen)度(du)傳感器(qi)信號，經PID運(yun)算(suan)后調節電(dian)加(jia)熱(re)(re)(re)器(qi)輸出(chu)功(gong)(gong)率(lv)，對發(fa)熱(re)(re)(re)元件(jian)(jian)的(de)電(dian)阻性(xing)負載(zai)實(shi)現溫(wen)(wen)度(du)控制。使(shi)介(jie)質溫(wen)(wen)度(du)均(jun)勻，達(da)(da)到所需(xu)(xu)(xu)要(yao)求;當發(fa)熱(re)(re)(re)元件(jian)(jian)超溫(wen)(wen)或低液位時(shi)，發(fa)熱(re)(re)(re)元件(jian)(jian)的(de)聯鎖保護(hu)裝置立即切斷加(jia)熱(re)(re)(re)電(dian)源避(bi)免發(fa)熱(re)(re)(re)元件(jian)(jian)燒壞，延長使(shi)用壽命。

產品特點

法蘭式(shi)電(dian)加熱(re)管表面功率(lv)大，是(shi)空氣加熱(re)表面負(fu)荷的2~4倍高(gao)度密集(ji)式(shi)、結(jie)構緊(jin)(jin)湊。由于(yu)整(zheng)體短而密集(ji)，故穩(wen)定性好，安(an)裝(zhuang)無需(xu)支架組(zu)合式(shi)大多(duo)采(cai)用(yong)氬(ya)弧焊(han)接(jie)方式(shi)使(shi)電(dian)熱(re)管于(yu)法蘭連(lian)接(jie)，也(ye)可(ke)利用(yong)緊(jin)(jin)固(gu)(gu)(gu)裝(zhuang)置的形式(shi)，即每支電(dian)熱(re)管上(shang)焊(han)由緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)。然(ran)后(hou)與法蘭蓋采(cai)用(yong)螺母鎖緊(jin)(jin)。管子(zi)于(yu)緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)采(cai)用(yong)氬(ya)弧焊(han)接(jie)，緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)密封處采(cai)用(yong)科學的工藝。單(dan)支更換(huan)方便，節約以后(hou)的維修(xiu)成本(ben)。
