法(fa)蘭式電(dian)(dian)加熱管(guan)是采用U型管(guan)狀電(dian)(dian)熱元件，依(yi)據加熱不同介(jie)(jie)質設(she)計規范，按(an)照功率配置(zhi)(zhi)要求(qiu)裝(zhuang)配在法(fa)蘭蓋上，插入需加熱物料中，發(fa)熱元件工作時(shi)所發(fa)出(chu)的大量熱量傳導給被(bei)加熱介(jie)(jie)質使(shi)介(jie)(jie)質溫度(du)升高，達(da)到所需的工藝要求(qiu)。當(dang)介(jie)(jie)質溫度(du)達(da)到工藝要求(qiu)的設(she)定值時(shi)控制系(xi)統根據溫度(du)傳感(gan)器(qi)信號，經PID運算后調節(jie)電(dian)(dian)加熱器(qi)輸出(chu)功率，對發(fa)熱元件的電(dian)(dian)阻(zu)性負(fu)載實現溫度(du)控制。使(shi)介(jie)(jie)質溫度(du)均勻，達(da)到所需要求(qiu);當(dang)發(fa)熱元件超溫或低液位時(shi)，發(fa)熱元件的聯(lian)鎖保護裝(zhuang)置(zhi)(zhi)立即切斷(duan)加熱電(dian)(dian)源避免發(fa)熱元件燒壞，延長使(shi)用壽命(ming)。

產品特點

法蘭式(shi)(shi)電加熱(re)管(guan)表面功(gong)率(lv)大，是(shi)空氣加熱(re)表面負荷的2~4倍(bei)高度密集(ji)式(shi)(shi)、結(jie)構(gou)緊(jin)(jin)(jin)湊。由于(yu)整體短而密集(ji)，故穩(wen)定性好(hao)，安裝(zhuang)無需支(zhi)架組合式(shi)(shi)大多(duo)采(cai)用(yong)(yong)(yong)氬弧(hu)焊接(jie)方式(shi)(shi)使(shi)電熱(re)管(guan)于(yu)法蘭連接(jie)，也(ye)可利用(yong)(yong)(yong)緊(jin)(jin)(jin)固(gu)裝(zhuang)置的形式(shi)(shi)，即每支(zhi)電熱(re)管(guan)上焊由緊(jin)(jin)(jin)固(gu)件(jian)(jian)。然后與法蘭蓋(gai)采(cai)用(yong)(yong)(yong)螺母(mu)鎖緊(jin)(jin)(jin)。管(guan)子于(yu)緊(jin)(jin)(jin)固(gu)件(jian)(jian)采(cai)用(yong)(yong)(yong)氬弧(hu)焊接(jie)，緊(jin)(jin)(jin)固(gu)件(jian)(jian)密封(feng)處(chu)采(cai)用(yong)(yong)(yong)科學的工(gong)藝。單支(zhi)更換(huan)方便，節約以后的維(wei)修成本。
