防爆法蘭電熱器性能及使用
法蘭加(jia)熱器是由多支加(jia)熱管焊接(jie)在法蘭上集(ji)中(zhong)加(jia)熱。主(zhu)要用于敞(chang)開式、封閉式的溶液箱和循環系統中(zhong)加(jia)熱用。
防爆法蘭電熱器優點
防爆法蘭(lan)電熱(re)管(guan)(guan)表(biao)面(mian)(mian)功率大,使(shi)空(kong)氣(qi)加熱(re)表(biao)面(mian)(mian)負荷的2~4倍(bei),高度密集(ji)式(shi)(shi)、結構緊湊(cou)。由于整體短而密集(ji),故穩定(ding)性(xing)好(hao),安裝(zhuang)無需支(zhi)架(jia)。 組合式(shi)(shi)法蘭(lan)加熱(re)器大多(duo)采用(yong)氬弧(hu)焊(han)接(jie)方式(shi)(shi)使(shi)電熱(re)管(guan)(guan)于法蘭(lan)連接(jie),也可(ke)利(li)用(yong)緊固(gu)(gu)裝(zhuang)置(zhi)的形式(shi)(shi),即每支(zhi)電熱(re)管(guan)(guan)上焊(han)由緊固(gu)(gu)件。然后(hou)與法蘭(lan)蓋采用(yong)螺母鎖(suo)緊。管(guan)(guan)子于緊固(gu)(gu)件采用(yong)氬弧(hu)焊(han)接(jie),永(yong)不泄漏。緊固(gu)(gu)件密封(feng)處采用(yong)科(ke)學的工藝(yi)。單(dan)支(zhi)更換極為方便,大大節(jie)約以后(hou)的維修成(cheng)本 選擇進口及國內優質材料。科(ke)學的生產工藝(yi),嚴(yan)格(ge)的質量(liang)管(guan)(guan)理,保證電熱(re)管(guan)(guan)優越的電氣(qi)性(xing)能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)熱(re)(re)(re)(re)器(qi):是采(cai)用U型管狀電熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian),依據加(jia)熱(re)(re)(re)(re)不(bu)同(tong)介(jie)質(zhi)設(she)計規范,按照功率配置要(yao)求裝配在法蘭蓋上,插入(ru)需(xu)加(jia)熱(re)(re)(re)(re)物料中,發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)工(gong)作(zuo)時(shi)所(suo)發(fa)出的(de)(de)大量熱(re)(re)(re)(re)量傳(chuan)導(dao)給被加(jia)熱(re)(re)(re)(re)介(jie)質(zhi)使(shi)(shi)介(jie)質(zhi)溫(wen)(wen)(wen)度升高(gao),達到(dao)(dao)所(suo)需(xu)的(de)(de)工(gong)藝要(yao)求。當介(jie)質(zhi)溫(wen)(wen)(wen)度達到(dao)(dao)工(gong)藝要(yao)求的(de)(de)設(she)定值時(shi),控制系(xi)統根據溫(wen)(wen)(wen)度傳(chuan)感器(qi)信號,經PID 運算后調節(jie)電加(jia)熱(re)(re)(re)(re)器(qi)輸(shu)出功率,對發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)(de)電阻性負載(zai)實(shi)現(xian)溫(wen)(wen)(wen)度控制。使(shi)(shi)介(jie)質(zhi)溫(wen)(wen)(wen)度均(jun)勻,達到(dao)(dao)所(suo)需(xu)要(yao)求;當發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)(wen)(wen)或(huo)低(di)液(ye)位時(shi),發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)(de)聯(lian)鎖保護裝置立即切(qie)斷(duan)加(jia)熱(re)(re)(re)(re)電源避免發(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)(jian)燒壞,延長使(shi)(shi)用壽命。
