法蘭(lan)式電(dian)加熱(re)(re)(re)管(guan)是采用U型管(guan)狀電(dian)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)，依(yi)據(ju)(ju)加熱(re)(re)(re)不同介(jie)質(zhi)設計(ji)規(gui)范，按(an)照功率(lv)配置(zhi)要(yao)(yao)求裝配在法蘭(lan)蓋(gai)上，插入需(xu)加熱(re)(re)(re)物料中，發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)工(gong)作時所發(fa)出的(de)大量(liang)熱(re)(re)(re)量(liang)傳導(dao)給被加熱(re)(re)(re)介(jie)質(zhi)使介(jie)質(zhi)溫(wen)度(du)升高(gao)，達(da)到(dao)所需(xu)的(de)工(gong)藝(yi)要(yao)(yao)求。當介(jie)質(zhi)溫(wen)度(du)達(da)到(dao)工(gong)藝(yi)要(yao)(yao)求的(de)設定值時控制系統根據(ju)(ju)溫(wen)度(du)傳感器信號(hao)，經(jing)PID運算后調節電(dian)加熱(re)(re)(re)器輸出功率(lv)，對發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的(de)電(dian)阻(zu)性負載實(shi)現溫(wen)度(du)控制。使介(jie)質(zhi)溫(wen)度(du)均(jun)勻，達(da)到(dao)所需(xu)要(yao)(yao)求;當發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)超(chao)溫(wen)或低(di)液位時，發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的(de)聯(lian)鎖保護(hu)裝置(zhi)立即切斷加熱(re)(re)(re)電(dian)源避免發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)燒壞，延長(chang)使用壽(shou)命。

產品特點

法(fa)蘭式(shi)(shi)(shi)電(dian)加熱(re)管表面功(gong)率大(da)，是空(kong)氣(qi)加熱(re)表面負荷的2~4倍(bei)高度密(mi)集(ji)式(shi)(shi)(shi)、結構緊(jin)(jin)湊(cou)。由(you)于整體短(duan)而密(mi)集(ji)，故穩定性好，安裝無(wu)需(xu)支架組(zu)合式(shi)(shi)(shi)大(da)多采用(yong)氬弧(hu)焊接方式(shi)(shi)(shi)使電(dian)熱(re)管于法(fa)蘭連接，也可利用(yong)緊(jin)(jin)固(gu)裝置的形式(shi)(shi)(shi)，即(ji)每支電(dian)熱(re)管上焊由(you)緊(jin)(jin)固(gu)件。然后(hou)與法(fa)蘭蓋(gai)采用(yong)螺母(mu)鎖緊(jin)(jin)。管子于緊(jin)(jin)固(gu)件采用(yong)氬弧(hu)焊接，緊(jin)(jin)固(gu)件密(mi)封(feng)處采用(yong)科學的工藝。單(dan)支更換方便，節約以后(hou)的維修成本。
