法蘭電加熱管也稱插入式電加熱器
法蘭電加熱管性能及使用
法蘭加熱器(qi)是由(you)多支加熱管焊接在法蘭上集中加熱。主(zhu)要用(yong)于(yu)敞開(kai)式(shi)、封閉式(shi)的溶(rong)液箱和循環系(xi)統(tong)中加熱用(yong)。
法(fa)蘭電加熱管(guan)優(you)點(dian)
表面功率大,使空(kong)氣加熱(re)(re)(re)表面負荷的(de)2~4倍(bei),高(gao)度密集式、結(jie)構(gou)緊(jin)(jin)湊。由于整體短而密集,法(fa)(fa)(fa)蘭(lan)(lan)(lan)電(dian)加熱(re)(re)(re)管(guan)(guan)(guan)故穩定性(xing)好(hao),安裝(zhuang)無需支架。 組合式法(fa)(fa)(fa)蘭(lan)(lan)(lan)加熱(re)(re)(re)器大多(duo)采(cai)用(yong)(yong)(yong)(yong)氬(ya)弧(hu)焊接方(fang)式使電(dian)熱(re)(re)(re)管(guan)(guan)(guan)于法(fa)(fa)(fa)蘭(lan)(lan)(lan)連接,也可利用(yong)(yong)(yong)(yong)緊(jin)(jin)固(gu)(gu)裝(zhuang)置的(de)形(xing)式,即(ji)每(mei)支電(dian)熱(re)(re)(re)管(guan)(guan)(guan)上焊由緊(jin)(jin)固(gu)(gu)件。然后(hou)與(yu)法(fa)(fa)(fa)蘭(lan)(lan)(lan)蓋(gai)采(cai)用(yong)(yong)(yong)(yong)螺母鎖(suo)緊(jin)(jin)。管(guan)(guan)(guan)子于緊(jin)(jin)固(gu)(gu)件采(cai)用(yong)(yong)(yong)(yong)氬(ya)弧(hu)焊接,永(yong)不泄(xie)漏。緊(jin)(jin)固(gu)(gu)件密封處(chu)采(cai)用(yong)(yong)(yong)(yong)科學(xue)的(de)工藝。單支更換(huan)極為方(fang)便(bian),大大節約以(yi)后(hou)的(de)維修成本 選擇(ze)進口(kou)及(ji)國內優(you)質材料。科學(xue)的(de)生產工藝,嚴格的(de)質量(liang)管(guan)(guan)(guan)理,保證電(dian)熱(re)(re)(re)管(guan)(guan)(guan)優(you)越的(de)電(dian)氣性(xing)能。
法(fa)蘭電加(jia)熱管概述(shu)及工作原理(li)
法蘭加熱(re)(re)(re)器:是采用(yong)U型管(guan)狀電(dian)熱(re)(re)(re)元(yuan)(yuan)(yuan)件,依(yi)據加熱(re)(re)(re)不同(tong)介(jie)質(zhi)(zhi)(zhi)設計規范,按照功(gong)率配(pei)置要(yao)求裝配(pei)在法蘭蓋上(shang),插(cha)入(ru)需(xu)加熱(re)(re)(re)物料中(zhong),發熱(re)(re)(re)元(yuan)(yuan)(yuan)件工作時所(suo)發出的(de)大量熱(re)(re)(re)量傳導(dao)給被加熱(re)(re)(re)介(jie)質(zhi)(zhi)(zhi)使介(jie)質(zhi)(zhi)(zhi)溫(wen)度(du)升(sheng)高,達到所(suo)需(xu)的(de)工藝要(yao)求。當介(jie)質(zhi)(zhi)(zhi)溫(wen)度(du)達到工藝要(yao)求的(de)設定(ding)值(zhi)時,控(kong)制(zhi)系(xi)統(tong)根據溫(wen)度(du)傳感器信號,經PID 運算(suan)后調節電(dian)加熱(re)(re)(re)器輸出功(gong)率,對(dui)發熱(re)(re)(re)元(yuan)(yuan)(yuan)件的(de)電(dian)阻性負載實現(xian)溫(wen)度(du)控(kong)制(zhi)。使介(jie)質(zhi)(zhi)(zhi)溫(wen)度(du)均勻,達到所(suo)需(xu)要(yao)求;當發熱(re)(re)(re)元(yuan)(yuan)(yuan)件超溫(wen)或低液位時,發熱(re)(re)(re)元(yuan)(yuan)(yuan)件的(de)聯鎖保護裝置立即切斷加熱(re)(re)(re)電(dian)源避免發熱(re)(re)(re)元(yuan)(yuan)(yuan)件燒壞(huai),延長使用(yong)壽命。
