防爆法蘭電熱器性能及使用
法蘭加熱(re)器是由多支加熱(re)管焊接在法蘭上集中加熱(re)。主(zhu)要用于敞開式、封閉式的溶(rong)液箱和循環系(xi)統中加熱(re)用。
防爆法蘭電熱器優點
防爆(bao)法(fa)蘭(lan)電(dian)熱管(guan)(guan)表面功率(lv)大,使空氣(qi)加(jia)熱表面負荷的(de)(de)2~4倍(bei),高度密(mi)集式、結(jie)構緊湊。由于整體短而密(mi)集,故穩定性好,安裝無需支架。 組合式法(fa)蘭(lan)加(jia)熱器大多采(cai)(cai)用(yong)(yong)氬弧焊接方式使電(dian)熱管(guan)(guan)于法(fa)蘭(lan)連(lian)接,也可利(li)用(yong)(yong)緊固(gu)裝置的(de)(de)形式,即每支電(dian)熱管(guan)(guan)上焊由緊固(gu)件。然后(hou)與法(fa)蘭(lan)蓋(gai)采(cai)(cai)用(yong)(yong)螺母鎖(suo)緊。管(guan)(guan)子于緊固(gu)件采(cai)(cai)用(yong)(yong)氬弧焊接,永不泄漏。緊固(gu)件密(mi)封處采(cai)(cai)用(yong)(yong)科學的(de)(de)工藝。單支更換極(ji)為(wei)方便(bian),大大節約以后(hou)的(de)(de)維修(xiu)成本 選擇進口及國內優質(zhi)材(cai)料。科學的(de)(de)生產工藝,嚴格的(de)(de)質(zhi)量(liang)管(guan)(guan)理,保(bao)證電(dian)熱管(guan)(guan)優越的(de)(de)電(dian)氣(qi)性能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)(jia)熱(re)(re)(re)器(qi):是采(cai)用(yong)(yong)U型管狀電熱(re)(re)(re)元(yuan)(yuan)件(jian)(jian),依(yi)據加(jia)(jia)熱(re)(re)(re)不同介質(zhi)設計規范,按照功(gong)率配(pei)置要(yao)求(qiu)裝配(pei)在法蘭蓋上(shang),插入(ru)需加(jia)(jia)熱(re)(re)(re)物料中(zhong),發(fa)熱(re)(re)(re)元(yuan)(yuan)件(jian)(jian)工(gong)作(zuo)時(shi)所發(fa)出的(de)大量熱(re)(re)(re)量傳(chuan)導給被加(jia)(jia)熱(re)(re)(re)介質(zhi)使(shi)(shi)介質(zhi)溫(wen)度(du)(du)(du)升高,達到所需的(de)工(gong)藝(yi)要(yao)求(qiu)。當介質(zhi)溫(wen)度(du)(du)(du)達到工(gong)藝(yi)要(yao)求(qiu)的(de)設定(ding)值(zhi)時(shi),控制(zhi)系統根據溫(wen)度(du)(du)(du)傳(chuan)感器(qi)信號,經PID 運(yun)算(suan)后(hou)調節(jie)電加(jia)(jia)熱(re)(re)(re)器(qi)輸出功(gong)率,對發(fa)熱(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)電阻性負載實現(xian)溫(wen)度(du)(du)(du)控制(zhi)。使(shi)(shi)介質(zhi)溫(wen)度(du)(du)(du)均勻,達到所需要(yao)求(qiu);當發(fa)熱(re)(re)(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)或(huo)低液位時(shi),發(fa)熱(re)(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)聯鎖保護裝置立即切(qie)斷(duan)加(jia)(jia)熱(re)(re)(re)電源避免(mian)發(fa)熱(re)(re)(re)元(yuan)(yuan)件(jian)(jian)燒壞,延長使(shi)(shi)用(yong)(yong)壽命(ming)。
