法蘭加(jia)熱(re)(re)(re)(re)管(guan)(guan)(也稱插入(ru)(ru)式電(dian)加(jia)熱(re)(re)(re)(re)器(qi)):是采用(yong)(yong)U型(xing)管(guan)(guan)狀電(dian)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)，依據加(jia)熱(re)(re)(re)(re)不同介(jie)(jie)質(zhi)(zhi)(zhi)設(she)計規范，按照功率配(pei)置要(yao)求裝配(pei)在法蘭蓋上，插入(ru)(ru)需加(jia)熱(re)(re)(re)(re)物(wu)料中，發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)工作時(shi)所發(fa)(fa)出的大量(liang)熱(re)(re)(re)(re)量(liang)傳導給被加(jia)熱(re)(re)(re)(re)介(jie)(jie)質(zhi)(zhi)(zhi)使介(jie)(jie)質(zhi)(zhi)(zhi)溫(wen)度(du)升高，達(da)到所需的工藝要(yao)求。當介(jie)(jie)質(zhi)(zhi)(zhi)溫(wen)度(du)達(da)到工藝要(yao)求的設(she)定值時(shi)控制(zhi)(zhi)系統(tong)根據溫(wen)度(du)傳感器(qi)信號，經PID運算后調節電(dian)加(jia)熱(re)(re)(re)(re)器(qi)輸出功率，對發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的電(dian)阻性負載實現(xian)溫(wen)度(du)控制(zhi)(zhi)。使介(jie)(jie)質(zhi)(zhi)(zhi)溫(wen)度(du)均勻，達(da)到所需要(yao)求;當發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)或低液位時(shi)，發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的聯鎖保護裝置立即切(qie)斷加(jia)熱(re)(re)(re)(re)電(dian)源避免(mian)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)燒(shao)壞(huai)，延長(chang)使用(yong)(yong)壽命。

產品特點

法蘭(lan)加熱管(guan)(guan)表(biao)面功率大，是空氣加熱表(biao)面負荷的(de)(de)2~4倍高度密集式(shi)、結構(gou)緊(jin)湊。由于(yu)整(zheng)體短而密集，故穩定(ding)性好，安裝無需(xu)支架(jia)組合式(shi)大多(duo)采用(yong)(yong)(yong)氬(ya)弧焊接方式(shi)使電熱管(guan)(guan)于(yu)法蘭(lan)連(lian)接，也可利用(yong)(yong)(yong)緊(jin)固裝置的(de)(de)形式(shi)，即每支電熱管(guan)(guan)上焊由緊(jin)固件。然后與法蘭(lan)蓋采用(yong)(yong)(yong)螺母鎖緊(jin)。管(guan)(guan)子于(yu)緊(jin)固件采用(yong)(yong)(yong)氬(ya)弧焊接，緊(jin)固件密封處采用(yong)(yong)(yong)科學(xue)的(de)(de)工(gong)藝。單支更換方便，節約(yue)以后的(de)(de)維修成本(ben)。
