法蘭式(shi)電(dian)加(jia)(jia)熱(re)(re)管是采用(yong)U型管狀(zhuang)電(dian)熱(re)(re)元(yuan)(yuan)件(jian)(jian)，依據(ju)加(jia)(jia)熱(re)(re)不同(tong)介質設(she)計規范，按照功率(lv)配(pei)置(zhi)要(yao)(yao)求(qiu)裝配(pei)在法蘭蓋(gai)上，插入需(xu)加(jia)(jia)熱(re)(re)物料中，發(fa)熱(re)(re)元(yuan)(yuan)件(jian)(jian)工(gong)作時(shi)所(suo)發(fa)出(chu)的大量熱(re)(re)量傳導給被加(jia)(jia)熱(re)(re)介質使介質溫度(du)(du)升高，達(da)到(dao)所(suo)需(xu)的工(gong)藝要(yao)(yao)求(qiu)。當介質溫度(du)(du)達(da)到(dao)工(gong)藝要(yao)(yao)求(qiu)的設(she)定值時(shi)控制系統(tong)根據(ju)溫度(du)(du)傳感器信號，經PID運算(suan)后調節電(dian)加(jia)(jia)熱(re)(re)器輸出(chu)功率(lv)，對發(fa)熱(re)(re)元(yuan)(yuan)件(jian)(jian)的電(dian)阻性負載實現溫度(du)(du)控制。使介質溫度(du)(du)均(jun)勻，達(da)到(dao)所(suo)需(xu)要(yao)(yao)求(qiu);當發(fa)熱(re)(re)元(yuan)(yuan)件(jian)(jian)超溫或低(di)液位時(shi)，發(fa)熱(re)(re)元(yuan)(yuan)件(jian)(jian)的聯(lian)鎖保護(hu)裝置(zhi)立即切斷(duan)加(jia)(jia)熱(re)(re)電(dian)源避免(mian)發(fa)熱(re)(re)元(yuan)(yuan)件(jian)(jian)燒壞(huai)，延長使用(yong)壽命。

產品特點

法蘭式(shi)(shi)(shi)電加熱(re)(re)(re)管表面功率大，是空(kong)氣加熱(re)(re)(re)表面負荷(he)的(de)(de)2~4倍高度密(mi)(mi)集式(shi)(shi)(shi)、結構緊(jin)(jin)湊。由于整體(ti)短而密(mi)(mi)集，故穩定性好，安裝(zhuang)無需支(zhi)架組(zu)合式(shi)(shi)(shi)大多采用(yong)氬(ya)弧焊接(jie)方式(shi)(shi)(shi)使電熱(re)(re)(re)管于法蘭連接(jie)，也可利用(yong)緊(jin)(jin)固裝(zhuang)置的(de)(de)形式(shi)(shi)(shi)，即每支(zhi)電熱(re)(re)(re)管上焊由緊(jin)(jin)固件(jian)。然后與法蘭蓋(gai)采用(yong)螺母鎖緊(jin)(jin)。管子于緊(jin)(jin)固件(jian)采用(yong)氬(ya)弧焊接(jie)，緊(jin)(jin)固件(jian)密(mi)(mi)封處采用(yong)科學的(de)(de)工藝。單支(zhi)更換方便，節約(yue)以后的(de)(de)維修成本。
