法蘭式電(dian)(dian)加熱(re)(re)管是采用U型管狀電(dian)(dian)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)，依據(ju)加熱(re)(re)不同介(jie)質(zhi)(zhi)設計規范，按照功率配(pei)置(zhi)要(yao)求(qiu)裝配(pei)在(zai)法蘭蓋上(shang)，插入需加熱(re)(re)物(wu)料中，發(fa)(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)工作(zuo)時(shi)所發(fa)(fa)出的大量熱(re)(re)量傳導給(gei)被加熱(re)(re)介(jie)質(zhi)(zhi)使(shi)介(jie)質(zhi)(zhi)溫(wen)(wen)度(du)(du)升高，達到所需的工藝要(yao)求(qiu)。當介(jie)質(zhi)(zhi)溫(wen)(wen)度(du)(du)達到工藝要(yao)求(qiu)的設定(ding)值時(shi)控制系統根據(ju)溫(wen)(wen)度(du)(du)傳感器(qi)信(xin)號(hao)，經PID運算后(hou)調節(jie)電(dian)(dian)加熱(re)(re)器(qi)輸出功率，對發(fa)(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)的電(dian)(dian)阻性負載實現溫(wen)(wen)度(du)(du)控制。使(shi)介(jie)質(zhi)(zhi)溫(wen)(wen)度(du)(du)均(jun)勻，達到所需要(yao)求(qiu);當發(fa)(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)超溫(wen)(wen)或低液位時(shi)，發(fa)(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)的聯鎖保護(hu)裝置(zhi)立即切斷(duan)加熱(re)(re)電(dian)(dian)源避(bi)免發(fa)(fa)熱(re)(re)元(yuan)(yuan)(yuan)件(jian)燒(shao)壞，延長使(shi)用壽命。

產品特點

法蘭式電加熱管表面功率大，是空氣加熱表面負荷的(de)(de)2~4倍(bei)高度密集(ji)式、結構緊(jin)湊。由于(yu)整體短(duan)而密集(ji)，故(gu)穩定性(xing)好，安裝(zhuang)無需支架組(zu)合式大多采(cai)用(yong)氬弧焊接(jie)方(fang)式使電熱管于(yu)法蘭連接(jie)，也可利用(yong)緊(jin)固(gu)裝(zhuang)置(zhi)的(de)(de)形(xing)式，即每支電熱管上焊由緊(jin)固(gu)件(jian)(jian)。然后與法蘭蓋采(cai)用(yong)螺母鎖緊(jin)。管子于(yu)緊(jin)固(gu)件(jian)(jian)采(cai)用(yong)氬弧焊接(jie)，緊(jin)固(gu)件(jian)(jian)密封處采(cai)用(yong)科(ke)學(xue)的(de)(de)工藝。單(dan)支更換方(fang)便(bian)，節約以后的(de)(de)維修(xiu)成(cheng)本(ben)。
