防爆法蘭電熱器性能及使用
法(fa)(fa)蘭加熱(re)器是(shi)由(you)多支加熱(re)管(guan)焊接在(zai)法(fa)(fa)蘭上集中(zhong)加熱(re)。主(zhu)要(yao)用于(yu)敞開(kai)式(shi)、封閉式(shi)的溶(rong)液箱和循環系(xi)統(tong)中(zhong)加熱(re)用。
防爆法蘭電熱器優點
防爆法蘭(lan)電(dian)(dian)熱管表(biao)(biao)面(mian)功率大(da),使空氣(qi)加熱表(biao)(biao)面(mian)負(fu)荷的(de)(de)(de)2~4倍,高(gao)度密集式(shi)(shi)、結(jie)構緊(jin)湊(cou)。由于(yu)整體短(duan)而密集,故穩定(ding)性好,安裝無需支(zhi)架。 組(zu)合式(shi)(shi)法蘭(lan)加熱器(qi)大(da)多(duo)采(cai)(cai)用(yong)(yong)氬(ya)弧焊接(jie)方(fang)式(shi)(shi)使電(dian)(dian)熱管于(yu)法蘭(lan)連(lian)接(jie),也可利用(yong)(yong)緊(jin)固(gu)(gu)裝置(zhi)的(de)(de)(de)形式(shi)(shi),即每支(zhi)電(dian)(dian)熱管上焊由緊(jin)固(gu)(gu)件(jian)。然后與法蘭(lan)蓋采(cai)(cai)用(yong)(yong)螺母鎖緊(jin)。管子(zi)于(yu)緊(jin)固(gu)(gu)件(jian)采(cai)(cai)用(yong)(yong)氬(ya)弧焊接(jie),永不泄漏。緊(jin)固(gu)(gu)件(jian)密封處采(cai)(cai)用(yong)(yong)科學的(de)(de)(de)工(gong)藝。單支(zhi)更(geng)換(huan)極為方(fang)便,大(da)大(da)節約(yue)以(yi)后的(de)(de)(de)維(wei)修成本 選擇進口及國(guo)內優(you)質材料。科學的(de)(de)(de)生產工(gong)藝,嚴格的(de)(de)(de)質量管理,保證電(dian)(dian)熱管優(you)越的(de)(de)(de)電(dian)(dian)氣(qi)性能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)熱(re)器(qi):是(shi)采(cai)用U型管狀電(dian)熱(re)元(yuan)件(jian)(jian),依據加(jia)熱(re)不同介質設計規范,按(an)照功率配置(zhi)(zhi)要(yao)求裝(zhuang)配在法蘭蓋(gai)上,插入需加(jia)熱(re)物料中(zhong),發(fa)(fa)熱(re)元(yuan)件(jian)(jian)工作(zuo)時(shi)所(suo)發(fa)(fa)出的(de)(de)大量熱(re)量傳導給被加(jia)熱(re)介質使(shi)(shi)介質溫(wen)(wen)(wen)度(du)升高,達到所(suo)需的(de)(de)工藝要(yao)求。當介質溫(wen)(wen)(wen)度(du)達到工藝要(yao)求的(de)(de)設定值時(shi),控制系統(tong)根據溫(wen)(wen)(wen)度(du)傳感器(qi)信號(hao),經PID 運算后(hou)調節(jie)電(dian)加(jia)熱(re)器(qi)輸出功率,對(dui)發(fa)(fa)熱(re)元(yuan)件(jian)(jian)的(de)(de)電(dian)阻性負載實現溫(wen)(wen)(wen)度(du)控制。使(shi)(shi)介質溫(wen)(wen)(wen)度(du)均勻,達到所(suo)需要(yao)求;當發(fa)(fa)熱(re)元(yuan)件(jian)(jian)超溫(wen)(wen)(wen)或低(di)液位(wei)時(shi),發(fa)(fa)熱(re)元(yuan)件(jian)(jian)的(de)(de)聯鎖(suo)保(bao)護(hu)裝(zhuang)置(zhi)(zhi)立即(ji)切斷加(jia)熱(re)電(dian)源避免(mian)發(fa)(fa)熱(re)元(yuan)件(jian)(jian)燒壞,延長(chang)使(shi)(shi)用壽命。
