法蘭(lan)加(jia)熱(re)(re)(re)(re)管(也稱插入式電(dian)加(jia)熱(re)(re)(re)(re)器(qi)):是采用(yong)U型管狀電(dian)熱(re)(re)(re)(re)元(yuan)件，依據加(jia)熱(re)(re)(re)(re)不同介質(zhi)設(she)計規范，按照功率配(pei)置要(yao)求(qiu)(qiu)裝配(pei)在(zai)法蘭(lan)蓋上，插入需加(jia)熱(re)(re)(re)(re)物料中，發(fa)熱(re)(re)(re)(re)元(yuan)件工(gong)作時(shi)所(suo)發(fa)出的大量(liang)(liang)熱(re)(re)(re)(re)量(liang)(liang)傳導(dao)給被加(jia)熱(re)(re)(re)(re)介質(zhi)使(shi)介質(zhi)溫(wen)(wen)度(du)升高，達到所(suo)需的工(gong)藝要(yao)求(qiu)(qiu)。當介質(zhi)溫(wen)(wen)度(du)達到工(gong)藝要(yao)求(qiu)(qiu)的設(she)定值時(shi)控制系統根據溫(wen)(wen)度(du)傳感器(qi)信號，經PID運算(suan)后調節電(dian)加(jia)熱(re)(re)(re)(re)器(qi)輸出功率，對發(fa)熱(re)(re)(re)(re)元(yuan)件的電(dian)阻性負載實現溫(wen)(wen)度(du)控制。使(shi)介質(zhi)溫(wen)(wen)度(du)均勻(yun)，達到所(suo)需要(yao)求(qiu)(qiu);當發(fa)熱(re)(re)(re)(re)元(yuan)件超(chao)溫(wen)(wen)或低液(ye)位時(shi)，發(fa)熱(re)(re)(re)(re)元(yuan)件的聯(lian)鎖(suo)保護裝置立即切斷加(jia)熱(re)(re)(re)(re)電(dian)源避免發(fa)熱(re)(re)(re)(re)元(yuan)件燒壞(huai)，延(yan)長使(shi)用(yong)壽命。

產品特點

法(fa)蘭(lan)加熱管(guan)表面(mian)功率大，是空氣加熱表面(mian)負荷的(de)(de)2~4倍(bei)高度密集式(shi)、結構(gou)緊(jin)湊。由于整體短而密集，故穩定性好，安裝無需(xu)支(zhi)(zhi)架組合(he)式(shi)大多采用(yong)(yong)(yong)氬弧(hu)焊接方(fang)式(shi)使電熱管(guan)于法(fa)蘭(lan)連接，也可利用(yong)(yong)(yong)緊(jin)固(gu)(gu)裝置的(de)(de)形式(shi)，即每支(zhi)(zhi)電熱管(guan)上(shang)焊由緊(jin)固(gu)(gu)件。然后與(yu)法(fa)蘭(lan)蓋采用(yong)(yong)(yong)螺母鎖(suo)緊(jin)。管(guan)子于緊(jin)固(gu)(gu)件采用(yong)(yong)(yong)氬弧(hu)焊接，緊(jin)固(gu)(gu)件密封處(chu)采用(yong)(yong)(yong)科學的(de)(de)工(gong)藝。單支(zhi)(zhi)更換方(fang)便，節約以后的(de)(de)維(wei)修(xiu)成(cheng)本。
