法蘭式電(dian)加(jia)(jia)熱(re)(re)(re)(re)管是采(cai)用(yong)U型管狀電(dian)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)，依據(ju)加(jia)(jia)熱(re)(re)(re)(re)不同介(jie)質設計(ji)規范，按照(zhao)功率配置要求(qiu)(qiu)裝配在法蘭蓋上，插入需(xu)加(jia)(jia)熱(re)(re)(re)(re)物料中，發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)工作時(shi)(shi)所(suo)發(fa)(fa)出的(de)大量熱(re)(re)(re)(re)量傳(chuan)導給被加(jia)(jia)熱(re)(re)(re)(re)介(jie)質使介(jie)質溫度(du)升高，達(da)到所(suo)需(xu)的(de)工藝(yi)要求(qiu)(qiu)。當(dang)介(jie)質溫度(du)達(da)到工藝(yi)要求(qiu)(qiu)的(de)設定值時(shi)(shi)控制系統根據(ju)溫度(du)傳(chuan)感器信號，經PID運算后調(diao)節電(dian)加(jia)(jia)熱(re)(re)(re)(re)器輸出功率，對(dui)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的(de)電(dian)阻(zu)性負載實現溫度(du)控制。使介(jie)質溫度(du)均(jun)勻(yun)，達(da)到所(suo)需(xu)要求(qiu)(qiu);當(dang)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)超溫或低液位時(shi)(shi)，發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的(de)聯鎖保護裝置立即切斷加(jia)(jia)熱(re)(re)(re)(re)電(dian)源避(bi)免發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)燒壞，延長使用(yong)壽命。

產品特點

法(fa)蘭式(shi)(shi)電加熱管表面功率(lv)大，是空氣加熱表面負荷的2~4倍高度密集式(shi)(shi)、結構緊(jin)(jin)(jin)湊。由(you)于(yu)(yu)整(zheng)體(ti)短(duan)而密集，故穩定(ding)性好(hao)，安裝無需支(zhi)(zhi)架組合式(shi)(shi)大多采(cai)用(yong)(yong)氬(ya)弧(hu)焊(han)接方式(shi)(shi)使電熱管于(yu)(yu)法(fa)蘭連接，也可利用(yong)(yong)緊(jin)(jin)(jin)固(gu)裝置的形式(shi)(shi)，即每支(zhi)(zhi)電熱管上焊(han)由(you)緊(jin)(jin)(jin)固(gu)件(jian)(jian)。然后與法(fa)蘭蓋采(cai)用(yong)(yong)螺母鎖緊(jin)(jin)(jin)。管子于(yu)(yu)緊(jin)(jin)(jin)固(gu)件(jian)(jian)采(cai)用(yong)(yong)氬(ya)弧(hu)焊(han)接，緊(jin)(jin)(jin)固(gu)件(jian)(jian)密封處采(cai)用(yong)(yong)科學的工藝(yi)。單支(zhi)(zhi)更(geng)換(huan)方便，節約以后的維修成(cheng)本。
