防爆法蘭電熱器性能及使用
法(fa)(fa)蘭加熱器是(shi)由多支加熱管焊接在法(fa)(fa)蘭上集中(zhong)(zhong)加熱。主(zhu)要(yao)用于敞開式(shi)、封(feng)閉式(shi)的(de)溶液箱和循環系統中(zhong)(zhong)加熱用。
防爆法蘭電熱器優點
防爆法(fa)蘭電(dian)熱(re)(re)管(guan)表面(mian)功(gong)率(lv)大,使空氣(qi)加熱(re)(re)表面(mian)負荷的(de)2~4倍,高度密(mi)(mi)集(ji)式(shi)、結(jie)構(gou)緊(jin)(jin)湊(cou)。由(you)于(yu)整體短(duan)而密(mi)(mi)集(ji),故穩(wen)定(ding)性好,安裝無需支(zhi)架(jia)。 組合(he)式(shi)法(fa)蘭加熱(re)(re)器大多采用(yong)(yong)(yong)氬(ya)弧焊(han)接(jie)方式(shi)使電(dian)熱(re)(re)管(guan)于(yu)法(fa)蘭連接(jie),也可利用(yong)(yong)(yong)緊(jin)(jin)固(gu)裝置的(de)形式(shi),即(ji)每(mei)支(zhi)電(dian)熱(re)(re)管(guan)上焊(han)由(you)緊(jin)(jin)固(gu)件。然后(hou)與法(fa)蘭蓋采用(yong)(yong)(yong)螺母(mu)鎖(suo)緊(jin)(jin)。管(guan)子于(yu)緊(jin)(jin)固(gu)件采用(yong)(yong)(yong)氬(ya)弧焊(han)接(jie),永(yong)不泄漏(lou)。緊(jin)(jin)固(gu)件密(mi)(mi)封處采用(yong)(yong)(yong)科(ke)學的(de)工藝。單支(zhi)更換極為方便(bian),大大節約以后(hou)的(de)維修成本 選擇進口及國內優(you)(you)質材(cai)料。科(ke)學的(de)生產工藝,嚴(yan)格的(de)質量(liang)管(guan)理,保證(zheng)電(dian)熱(re)(re)管(guan)優(you)(you)越(yue)的(de)電(dian)氣(qi)性能。
防爆法蘭電熱器概述及工作原理
法蘭(lan)(lan)加熱(re)(re)(re)(re)器:是采用(yong)U型(xing)管狀電(dian)熱(re)(re)(re)(re)元(yuan)件(jian),依據(ju)加熱(re)(re)(re)(re)不同介質(zhi)(zhi)設計規范(fan),按照功率配置要(yao)求(qiu)裝配在法蘭(lan)(lan)蓋上,插入(ru)需(xu)(xu)加熱(re)(re)(re)(re)物料中(zhong),發熱(re)(re)(re)(re)元(yuan)件(jian)工作時(shi)所發出的(de)(de)(de)大量熱(re)(re)(re)(re)量傳導給被加熱(re)(re)(re)(re)介質(zhi)(zhi)使介質(zhi)(zhi)溫(wen)(wen)度升高,達到所需(xu)(xu)的(de)(de)(de)工藝要(yao)求(qiu)。當介質(zhi)(zhi)溫(wen)(wen)度達到工藝要(yao)求(qiu)的(de)(de)(de)設定(ding)值時(shi),控(kong)制系(xi)統根(gen)據(ju)溫(wen)(wen)度傳感器信號,經PID 運算后調節(jie)電(dian)加熱(re)(re)(re)(re)器輸出功率,對發熱(re)(re)(re)(re)元(yuan)件(jian)的(de)(de)(de)電(dian)阻性負載實現溫(wen)(wen)度控(kong)制。使介質(zhi)(zhi)溫(wen)(wen)度均勻,達到所需(xu)(xu)要(yao)求(qiu);當發熱(re)(re)(re)(re)元(yuan)件(jian)超溫(wen)(wen)或低液位時(shi),發熱(re)(re)(re)(re)元(yuan)件(jian)的(de)(de)(de)聯鎖保護裝置立(li)即切斷加熱(re)(re)(re)(re)電(dian)源避免發熱(re)(re)(re)(re)元(yuan)件(jian)燒(shao)壞,延長使用(yong)壽(shou)命。
