法蘭式電(dian)加(jia)熱(re)(re)管是(shi)采(cai)用(yong)(yong)U型管狀電(dian)熱(re)(re)元件，依(yi)據加(jia)熱(re)(re)不(bu)同介(jie)質設計規范，按(an)照功(gong)率配(pei)置要(yao)(yao)(yao)求(qiu)(qiu)裝(zhuang)配(pei)在法蘭蓋上，插入需加(jia)熱(re)(re)物料中(zhong)，發熱(re)(re)元件工(gong)(gong)作時所發出(chu)的大量熱(re)(re)量傳(chuan)導(dao)給(gei)被加(jia)熱(re)(re)介(jie)質使介(jie)質溫(wen)(wen)(wen)度升(sheng)高，達(da)到(dao)(dao)(dao)所需的工(gong)(gong)藝(yi)要(yao)(yao)(yao)求(qiu)(qiu)。當介(jie)質溫(wen)(wen)(wen)度達(da)到(dao)(dao)(dao)工(gong)(gong)藝(yi)要(yao)(yao)(yao)求(qiu)(qiu)的設定(ding)值(zhi)時控(kong)(kong)制系統根據溫(wen)(wen)(wen)度傳(chuan)感器(qi)信號，經PID運算后調節電(dian)加(jia)熱(re)(re)器(qi)輸出(chu)功(gong)率，對發熱(re)(re)元件的電(dian)阻性負載(zai)實現(xian)溫(wen)(wen)(wen)度控(kong)(kong)制。使介(jie)質溫(wen)(wen)(wen)度均(jun)勻，達(da)到(dao)(dao)(dao)所需要(yao)(yao)(yao)求(qiu)(qiu);當發熱(re)(re)元件超溫(wen)(wen)(wen)或低(di)液位時，發熱(re)(re)元件的聯鎖保護裝(zhuang)置立即切斷加(jia)熱(re)(re)電(dian)源避免發熱(re)(re)元件燒壞，延長(chang)使用(yong)(yong)壽命(ming)。

產品特點

法蘭式(shi)電加熱(re)管(guan)表面功率大，是(shi)空氣加熱(re)表面負荷的(de)2~4倍高度密(mi)集式(shi)、結構緊(jin)湊。由于整體短而密(mi)集，故穩定性好，安裝無需支架(jia)組合式(shi)大多采用(yong)氬(ya)弧焊(han)(han)接(jie)方(fang)式(shi)使(shi)電熱(re)管(guan)于法蘭連接(jie)，也(ye)可利用(yong)緊(jin)固(gu)(gu)裝置的(de)形式(shi)，即每支電熱(re)管(guan)上焊(han)(han)由緊(jin)固(gu)(gu)件(jian)(jian)。然后與法蘭蓋采用(yong)螺母(mu)鎖緊(jin)。管(guan)子于緊(jin)固(gu)(gu)件(jian)(jian)采用(yong)氬(ya)弧焊(han)(han)接(jie)，緊(jin)固(gu)(gu)件(jian)(jian)密(mi)封處采用(yong)科(ke)學的(de)工藝。單支更換方(fang)便，節約以后的(de)維修成(cheng)本。
