法蘭式電(dian)(dian)加熱(re)管是采用U型管狀電(dian)(dian)熱(re)元(yuan)件(jian)(jian)(jian)，依據加熱(re)不同介(jie)質(zhi)(zhi)設(she)計(ji)規(gui)范，按(an)照(zhao)功(gong)率配置要(yao)求(qiu)裝配在法蘭蓋上，插(cha)入需(xu)加熱(re)物料中(zhong)，發熱(re)元(yuan)件(jian)(jian)(jian)工(gong)作時所(suo)發出的大(da)量(liang)熱(re)量(liang)傳導給(gei)被(bei)加熱(re)介(jie)質(zhi)(zhi)使介(jie)質(zhi)(zhi)溫度升高，達到(dao)所(suo)需(xu)的工(gong)藝要(yao)求(qiu)。當介(jie)質(zhi)(zhi)溫度達到(dao)工(gong)藝要(yao)求(qiu)的設(she)定值時控制系統根據溫度傳感器信號，經PID運算后調(diao)節電(dian)(dian)加熱(re)器輸出功(gong)率，對(dui)發熱(re)元(yuan)件(jian)(jian)(jian)的電(dian)(dian)阻性(xing)負(fu)載實現溫度控制。使介(jie)質(zhi)(zhi)溫度均(jun)勻，達到(dao)所(suo)需(xu)要(yao)求(qiu);當發熱(re)元(yuan)件(jian)(jian)(jian)超溫或低液位時，發熱(re)元(yuan)件(jian)(jian)(jian)的聯鎖保(bao)護裝置立即切斷加熱(re)電(dian)(dian)源(yuan)避(bi)免(mian)發熱(re)元(yuan)件(jian)(jian)(jian)燒壞(huai)，延長使用壽命(ming)。

產品特點

法蘭(lan)(lan)(lan)式電加(jia)熱管表面功率大(da)，是空(kong)氣加(jia)熱表面負荷的(de)2~4倍(bei)高度密集式、結構緊湊。由于(yu)整體(ti)短而密集，故穩(wen)定(ding)性(xing)好，安(an)裝(zhuang)無需支架組(zu)合式大(da)多采(cai)(cai)用(yong)氬(ya)弧(hu)焊(han)接方(fang)式使電熱管于(yu)法蘭(lan)(lan)(lan)連接，也可利用(yong)緊固(gu)(gu)(gu)裝(zhuang)置的(de)形式，即每支電熱管上焊(han)由緊固(gu)(gu)(gu)件(jian)。然(ran)后(hou)(hou)與法蘭(lan)(lan)(lan)蓋采(cai)(cai)用(yong)螺母(mu)鎖緊。管子于(yu)緊固(gu)(gu)(gu)件(jian)采(cai)(cai)用(yong)氬(ya)弧(hu)焊(han)接，緊固(gu)(gu)(gu)件(jian)密封處采(cai)(cai)用(yong)科學的(de)工(gong)藝。單(dan)支更換方(fang)便，節(jie)約以(yi)后(hou)(hou)的(de)維修(xiu)成(cheng)本。
