法蘭式電(dian)(dian)加(jia)熱(re)(re)管(guan)是采用U型管(guan)狀電(dian)(dian)熱(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)，依據(ju)加(jia)熱(re)(re)不同介(jie)質設計規范，按照功(gong)率配置(zhi)要(yao)(yao)求(qiu)裝配在法蘭蓋(gai)上，插入(ru)需(xu)加(jia)熱(re)(re)物料中，發(fa)熱(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)工作時(shi)所發(fa)出(chu)的大量(liang)熱(re)(re)量(liang)傳導給被加(jia)熱(re)(re)介(jie)質使介(jie)質溫(wen)度(du)升高，達(da)到所需(xu)的工藝要(yao)(yao)求(qiu)。當介(jie)質溫(wen)度(du)達(da)到工藝要(yao)(yao)求(qiu)的設定值時(shi)控制系(xi)統根據(ju)溫(wen)度(du)傳感器(qi)信號(hao)，經PID運算后調節(jie)電(dian)(dian)加(jia)熱(re)(re)器(qi)輸出(chu)功(gong)率，對發(fa)熱(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的電(dian)(dian)阻性負載實(shi)現溫(wen)度(du)控制。使介(jie)質溫(wen)度(du)均勻，達(da)到所需(xu)要(yao)(yao)求(qiu);當發(fa)熱(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)超(chao)溫(wen)或低液位時(shi)，發(fa)熱(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的聯鎖保護裝置(zhi)立即切斷(duan)加(jia)熱(re)(re)電(dian)(dian)源避免發(fa)熱(re)(re)元(yuan)(yuan)(yuan)(yuan)件(jian)(jian)燒壞，延(yan)長使用壽命(ming)。

產品特點

法(fa)蘭式(shi)電加(jia)熱管(guan)(guan)(guan)表面功率大(da)，是空氣加(jia)熱表面負荷的2~4倍高(gao)度密集式(shi)、結(jie)構緊(jin)湊。由(you)于(yu)整體短(duan)而密集，故(gu)穩定性好，安裝(zhuang)無需支架組合(he)式(shi)大(da)多采(cai)用氬(ya)弧焊(han)接方式(shi)使電熱管(guan)(guan)(guan)于(yu)法(fa)蘭連接，也可(ke)利用緊(jin)固(gu)裝(zhuang)置的形式(shi)，即每(mei)支電熱管(guan)(guan)(guan)上焊(han)由(you)緊(jin)固(gu)件(jian)(jian)。然后與法(fa)蘭蓋采(cai)用螺母鎖緊(jin)。管(guan)(guan)(guan)子于(yu)緊(jin)固(gu)件(jian)(jian)采(cai)用氬(ya)弧焊(han)接，緊(jin)固(gu)件(jian)(jian)密封處(chu)采(cai)用科學的工藝。單支更換方便，節(jie)約以后的維修(xiu)成本。
