法蘭式電(dian)加(jia)熱管是(shi)采用(yong)U型管狀(zhuang)電(dian)熱元件(jian)(jian)，依據加(jia)熱不同介(jie)質(zhi)(zhi)(zhi)設計規范，按照(zhao)功(gong)(gong)率配置要(yao)求裝配在法蘭蓋上，插入需加(jia)熱物料(liao)中，發(fa)熱元件(jian)(jian)工(gong)作時所(suo)發(fa)出(chu)的大量熱量傳導給(gei)被加(jia)熱介(jie)質(zhi)(zhi)(zhi)使(shi)介(jie)質(zhi)(zhi)(zhi)溫(wen)(wen)(wen)度(du)(du)升高，達到(dao)所(suo)需的工(gong)藝要(yao)求。當(dang)介(jie)質(zhi)(zhi)(zhi)溫(wen)(wen)(wen)度(du)(du)達到(dao)工(gong)藝要(yao)求的設定值時控(kong)(kong)制(zhi)系統根(gen)據溫(wen)(wen)(wen)度(du)(du)傳感器信號，經PID運算(suan)后調(diao)節電(dian)加(jia)熱器輸(shu)出(chu)功(gong)(gong)率，對發(fa)熱元件(jian)(jian)的電(dian)阻性負(fu)載實現溫(wen)(wen)(wen)度(du)(du)控(kong)(kong)制(zhi)。使(shi)介(jie)質(zhi)(zhi)(zhi)溫(wen)(wen)(wen)度(du)(du)均勻，達到(dao)所(suo)需要(yao)求;當(dang)發(fa)熱元件(jian)(jian)超溫(wen)(wen)(wen)或低液(ye)位時，發(fa)熱元件(jian)(jian)的聯鎖保護裝置立即切斷加(jia)熱電(dian)源避免(mian)發(fa)熱元件(jian)(jian)燒(shao)壞(huai)，延(yan)長使(shi)用(yong)壽命。

產品特點

法(fa)(fa)蘭式(shi)電(dian)加熱(re)管(guan)(guan)表(biao)面功率大，是空氣加熱(re)表(biao)面負荷(he)的(de)(de)2~4倍(bei)高度密集式(shi)、結構緊湊。由(you)于(yu)整體(ti)短(duan)而密集，故穩(wen)定(ding)性好，安裝(zhuang)無需支(zhi)架組合式(shi)大多采(cai)用氬(ya)弧焊(han)接方式(shi)使(shi)電(dian)熱(re)管(guan)(guan)于(yu)法(fa)(fa)蘭連(lian)接，也可(ke)利用緊固(gu)裝(zhuang)置的(de)(de)形式(shi)，即每(mei)支(zhi)電(dian)熱(re)管(guan)(guan)上焊(han)由(you)緊固(gu)件。然后(hou)與(yu)法(fa)(fa)蘭蓋(gai)采(cai)用螺母鎖緊。管(guan)(guan)子(zi)于(yu)緊固(gu)件采(cai)用氬(ya)弧焊(han)接，緊固(gu)件密封處采(cai)用科學的(de)(de)工藝。單支(zhi)更換(huan)方便，節約以后(hou)的(de)(de)維修成本。
