防爆法蘭電熱器性能及使用
法蘭(lan)加(jia)(jia)(jia)熱(re)(re)器(qi)是由多支加(jia)(jia)(jia)熱(re)(re)管焊(han)接在法蘭(lan)上集中(zhong)加(jia)(jia)(jia)熱(re)(re)。主要(yao)用于敞開式(shi)、封閉(bi)式(shi)的溶液(ye)箱(xiang)和循環系統中(zhong)加(jia)(jia)(jia)熱(re)(re)用。
防爆法蘭電熱器優點
防爆法(fa)蘭電熱(re)管(guan)(guan)(guan)表(biao)面(mian)功率大(da),使空氣加(jia)熱(re)表(biao)面(mian)負荷的2~4倍,高(gao)度(du)密(mi)集(ji)式、結構緊(jin)湊。由于(yu)(yu)整體短而密(mi)集(ji),故(gu)穩定性(xing)好,安(an)裝無(wu)需支架(jia)。 組(zu)合式法(fa)蘭加(jia)熱(re)器大(da)多(duo)采(cai)(cai)用(yong)(yong)氬弧(hu)焊接方式使電熱(re)管(guan)(guan)(guan)于(yu)(yu)法(fa)蘭連(lian)接,也(ye)可利用(yong)(yong)緊(jin)固(gu)裝置的形式,即(ji)每(mei)支電熱(re)管(guan)(guan)(guan)上(shang)焊由緊(jin)固(gu)件(jian)。然(ran)后與法(fa)蘭蓋(gai)采(cai)(cai)用(yong)(yong)螺(luo)母鎖緊(jin)。管(guan)(guan)(guan)子于(yu)(yu)緊(jin)固(gu)件(jian)采(cai)(cai)用(yong)(yong)氬弧(hu)焊接,永不泄漏。緊(jin)固(gu)件(jian)密(mi)封(feng)處采(cai)(cai)用(yong)(yong)科學(xue)的工藝(yi)。單(dan)支更換極(ji)為方便,大(da)大(da)節(jie)約(yue)以(yi)后的維(wei)修成本 選擇進(jin)口(kou)及(ji)國內優(you)質材(cai)料。科學(xue)的生產工藝(yi),嚴格的質量管(guan)(guan)(guan)理,保證電熱(re)管(guan)(guan)(guan)優(you)越的電氣性(xing)能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)(jia)熱(re)(re)器(qi):是采用U型管狀電(dian)熱(re)(re)元(yuan)(yuan)件(jian)(jian),依據(ju)(ju)加(jia)(jia)熱(re)(re)不(bu)同介質設計規(gui)范,按照功率配置要(yao)求(qiu)裝配在法蘭蓋上,插(cha)入需加(jia)(jia)熱(re)(re)物(wu)料中,發熱(re)(re)元(yuan)(yuan)件(jian)(jian)工作時所(suo)(suo)發出(chu)的(de)(de)(de)大(da)量(liang)熱(re)(re)量(liang)傳導給被加(jia)(jia)熱(re)(re)介質使(shi)(shi)介質溫(wen)度(du)(du)升高,達到所(suo)(suo)需的(de)(de)(de)工藝要(yao)求(qiu)。當介質溫(wen)度(du)(du)達到工藝要(yao)求(qiu)的(de)(de)(de)設定值時,控(kong)(kong)制系統根(gen)據(ju)(ju)溫(wen)度(du)(du)傳感(gan)器(qi)信(xin)號,經(jing)PID 運(yun)算后調節電(dian)加(jia)(jia)熱(re)(re)器(qi)輸出(chu)功率,對(dui)發熱(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)(de)(de)電(dian)阻性負載(zai)實現溫(wen)度(du)(du)控(kong)(kong)制。使(shi)(shi)介質溫(wen)度(du)(du)均勻,達到所(suo)(suo)需要(yao)求(qiu);當發熱(re)(re)元(yuan)(yuan)件(jian)(jian)超溫(wen)或低(di)液(ye)位時,發熱(re)(re)元(yuan)(yuan)件(jian)(jian)的(de)(de)(de)聯鎖保護裝置立即切斷加(jia)(jia)熱(re)(re)電(dian)源避(bi)免(mian)發熱(re)(re)元(yuan)(yuan)件(jian)(jian)燒壞,延長使(shi)(shi)用壽命。
