法蘭加(jia)(jia)(jia)熱(re)管(guan)(也稱(cheng)插入式電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)器(qi)):是采用U型(xing)管(guan)狀電(dian)(dian)(dian)熱(re)元(yuan)件(jian)，依(yi)據(ju)加(jia)(jia)(jia)熱(re)不同介(jie)質(zhi)(zhi)設計規(gui)范，按照功(gong)率配(pei)置(zhi)要(yao)求裝配(pei)在法蘭蓋(gai)上(shang)，插入需(xu)加(jia)(jia)(jia)熱(re)物(wu)料(liao)中，發(fa)熱(re)元(yuan)件(jian)工(gong)作時所(suo)發(fa)出的大量熱(re)量傳導給被加(jia)(jia)(jia)熱(re)介(jie)質(zhi)(zhi)使(shi)(shi)介(jie)質(zhi)(zhi)溫(wen)(wen)度(du)升高，達(da)到(dao)所(suo)需(xu)的工(gong)藝要(yao)求。當介(jie)質(zhi)(zhi)溫(wen)(wen)度(du)達(da)到(dao)工(gong)藝要(yao)求的設定值時控制系(xi)統根據(ju)溫(wen)(wen)度(du)傳感(gan)器(qi)信號，經(jing)PID運算后調節電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)器(qi)輸出功(gong)率，對發(fa)熱(re)元(yuan)件(jian)的電(dian)(dian)(dian)阻性負載實(shi)現(xian)溫(wen)(wen)度(du)控制。使(shi)(shi)介(jie)質(zhi)(zhi)溫(wen)(wen)度(du)均勻，達(da)到(dao)所(suo)需(xu)要(yao)求;當發(fa)熱(re)元(yuan)件(jian)超溫(wen)(wen)或(huo)低液位時，發(fa)熱(re)元(yuan)件(jian)的聯鎖保護裝置(zhi)立即(ji)切斷加(jia)(jia)(jia)熱(re)電(dian)(dian)(dian)源避免發(fa)熱(re)元(yuan)件(jian)燒壞，延長使(shi)(shi)用壽命。

產品特點

法(fa)蘭(lan)加熱(re)管表面(mian)功率大，是空氣(qi)加熱(re)表面(mian)負荷的(de)2~4倍高度密集式(shi)、結構緊(jin)湊。由于(yu)整體短而(er)密集，故穩定性(xing)好，安裝無(wu)需支(zhi)架(jia)組合式(shi)大多采(cai)用(yong)(yong)氬弧焊接方式(shi)使電熱(re)管于(yu)法(fa)蘭(lan)連接，也可(ke)利用(yong)(yong)緊(jin)固(gu)裝置(zhi)的(de)形(xing)式(shi)，即每支(zhi)電熱(re)管上焊由緊(jin)固(gu)件。然(ran)后與法(fa)蘭(lan)蓋采(cai)用(yong)(yong)螺母(mu)鎖(suo)緊(jin)。管子于(yu)緊(jin)固(gu)件采(cai)用(yong)(yong)氬弧焊接，緊(jin)固(gu)件密封處采(cai)用(yong)(yong)科學的(de)工藝。單支(zhi)更(geng)換方便，節約(yue)以后的(de)維(wei)修成本。
