法蘭式電(dian)(dian)加熱(re)(re)(re)管(guan)(guan)是采用(yong)U型管(guan)(guan)狀(zhuang)電(dian)(dian)熱(re)(re)(re)元(yuan)(yuan)件，依據(ju)(ju)加熱(re)(re)(re)不同介質設(she)計(ji)規范，按照功率配(pei)置要(yao)求裝配(pei)在法蘭蓋上，插入需加熱(re)(re)(re)物料中，發(fa)熱(re)(re)(re)元(yuan)(yuan)件工(gong)(gong)作時(shi)所發(fa)出的(de)大量熱(re)(re)(re)量傳導給被加熱(re)(re)(re)介質使(shi)介質溫(wen)度升高，達到(dao)所需的(de)工(gong)(gong)藝要(yao)求。當介質溫(wen)度達到(dao)工(gong)(gong)藝要(yao)求的(de)設(she)定值時(shi)控(kong)制系(xi)統根據(ju)(ju)溫(wen)度傳感(gan)器信號，經PID運算后調節(jie)電(dian)(dian)加熱(re)(re)(re)器輸出功率，對發(fa)熱(re)(re)(re)元(yuan)(yuan)件的(de)電(dian)(dian)阻性負載實現溫(wen)度控(kong)制。使(shi)介質溫(wen)度均(jun)勻，達到(dao)所需要(yao)求;當發(fa)熱(re)(re)(re)元(yuan)(yuan)件超(chao)溫(wen)或低液(ye)位時(shi)，發(fa)熱(re)(re)(re)元(yuan)(yuan)件的(de)聯鎖保(bao)護裝置立即(ji)切斷加熱(re)(re)(re)電(dian)(dian)源避免(mian)發(fa)熱(re)(re)(re)元(yuan)(yuan)件燒(shao)壞，延長使(shi)用(yong)壽(shou)命。

產品特點

法(fa)蘭式電(dian)(dian)加(jia)熱(re)管(guan)(guan)表面功率大，是(shi)空氣(qi)加(jia)熱(re)表面負(fu)荷的(de)2~4倍(bei)高(gao)度密集式、結構緊湊。由于整(zheng)體短而密集，故穩(wen)定(ding)性(xing)好，安裝無需支(zhi)架組合(he)式大多采(cai)用(yong)(yong)(yong)氬(ya)弧(hu)焊接(jie)方式使電(dian)(dian)熱(re)管(guan)(guan)于法(fa)蘭連接(jie)，也可利用(yong)(yong)(yong)緊固裝置(zhi)的(de)形式，即每支(zhi)電(dian)(dian)熱(re)管(guan)(guan)上焊由緊固件。然后與法(fa)蘭蓋(gai)采(cai)用(yong)(yong)(yong)螺母鎖緊。管(guan)(guan)子于緊固件采(cai)用(yong)(yong)(yong)氬(ya)弧(hu)焊接(jie)，緊固件密封處采(cai)用(yong)(yong)(yong)科學的(de)工藝。單(dan)支(zhi)更換方便(bian)，節約以后的(de)維修成本。
