法蘭(lan)式電(dian)(dian)(dian)(dian)加熱(re)(re)管(guan)是(shi)采用(yong)U型管(guan)狀電(dian)(dian)(dian)(dian)熱(re)(re)元(yuan)(yuan)件(jian)，依據(ju)加熱(re)(re)不同介(jie)質(zhi)設(she)計規范，按照功率配置要(yao)求(qiu)(qiu)裝(zhuang)配在法蘭(lan)蓋上，插入(ru)需加熱(re)(re)物料中，發熱(re)(re)元(yuan)(yuan)件(jian)工(gong)作時(shi)所(suo)(suo)發出的大量熱(re)(re)量傳(chuan)(chuan)導給被加熱(re)(re)介(jie)質(zhi)使介(jie)質(zhi)溫(wen)(wen)度升高，達到所(suo)(suo)需的工(gong)藝要(yao)求(qiu)(qiu)。當介(jie)質(zhi)溫(wen)(wen)度達到工(gong)藝要(yao)求(qiu)(qiu)的設(she)定值時(shi)控(kong)制系統根據(ju)溫(wen)(wen)度傳(chuan)(chuan)感(gan)器(qi)信號(hao)，經(jing)PID運算(suan)后(hou)調(diao)節電(dian)(dian)(dian)(dian)加熱(re)(re)器(qi)輸出功率，對發熱(re)(re)元(yuan)(yuan)件(jian)的電(dian)(dian)(dian)(dian)阻性負載實現溫(wen)(wen)度控(kong)制。使介(jie)質(zhi)溫(wen)(wen)度均勻，達到所(suo)(suo)需要(yao)求(qiu)(qiu);當發熱(re)(re)元(yuan)(yuan)件(jian)超溫(wen)(wen)或(huo)低液位時(shi)，發熱(re)(re)元(yuan)(yuan)件(jian)的聯(lian)鎖保護裝(zhuang)置立即切斷加熱(re)(re)電(dian)(dian)(dian)(dian)源避免發熱(re)(re)元(yuan)(yuan)件(jian)燒壞，延長使用(yong)壽命。

產品特點

法蘭(lan)式電加熱(re)管表面功率大(da)，是(shi)空氣加熱(re)表面負荷的2~4倍高度密集(ji)式、結(jie)構緊湊。由(you)于整體短而密集(ji)，故穩定(ding)性好，安(an)裝無需支(zhi)架組合式大(da)多采用(yong)(yong)氬(ya)弧(hu)焊(han)接方式使電熱(re)管于法蘭(lan)連接，也可利用(yong)(yong)緊固(gu)裝置(zhi)的形式，即每支(zhi)電熱(re)管上(shang)焊(han)由(you)緊固(gu)件。然(ran)后與法蘭(lan)蓋采用(yong)(yong)螺母鎖緊。管子(zi)于緊固(gu)件采用(yong)(yong)氬(ya)弧(hu)焊(han)接，緊固(gu)件密封處采用(yong)(yong)科學的工藝。單支(zhi)更換方便，節約以后的維(wei)修成(cheng)本。
