防爆法蘭電熱器性能及使用
法蘭加(jia)熱(re)(re)器是由多支加(jia)熱(re)(re)管(guan)焊接在法蘭上集(ji)中加(jia)熱(re)(re)。主要用于敞開式、封(feng)閉(bi)式的溶液箱和循環系統(tong)中加(jia)熱(re)(re)用。
防爆法蘭電熱器優點
防爆法(fa)蘭電(dian)(dian)(dian)熱(re)(re)(re)管表面功率大(da),使(shi)空(kong)氣加(jia)(jia)熱(re)(re)(re)表面負(fu)荷(he)的(de)2~4倍(bei),高度(du)密(mi)(mi)集式、結(jie)構緊湊(cou)。由于整體短而密(mi)(mi)集,故穩定性好,安裝無需(xu)支(zhi)架。 組(zu)合(he)式法(fa)蘭加(jia)(jia)熱(re)(re)(re)器(qi)大(da)多采(cai)用(yong)(yong)氬(ya)弧焊接(jie)(jie)方(fang)式使(shi)電(dian)(dian)(dian)熱(re)(re)(re)管于法(fa)蘭連接(jie)(jie),也(ye)可(ke)利用(yong)(yong)緊固(gu)裝置的(de)形式,即每支(zhi)電(dian)(dian)(dian)熱(re)(re)(re)管上焊由緊固(gu)件(jian)。然(ran)后與法(fa)蘭蓋采(cai)用(yong)(yong)螺母(mu)鎖緊。管子于緊固(gu)件(jian)采(cai)用(yong)(yong)氬(ya)弧焊接(jie)(jie),永不泄漏。緊固(gu)件(jian)密(mi)(mi)封處(chu)采(cai)用(yong)(yong)科(ke)學(xue)的(de)工藝。單支(zhi)更換極為方(fang)便,大(da)大(da)節約以后的(de)維修(xiu)成本 選擇進口(kou)及國內(nei)優質材(cai)料。科(ke)學(xue)的(de)生產(chan)工藝,嚴格的(de)質量管理,保證電(dian)(dian)(dian)熱(re)(re)(re)管優越的(de)電(dian)(dian)(dian)氣性能。
防爆法蘭電熱器概述及工作原理
法(fa)蘭加(jia)(jia)(jia)熱(re)(re)器(qi):是采用U型管狀(zhuang)電(dian)(dian)熱(re)(re)元(yuan)(yuan)(yuan)件(jian),依據(ju)加(jia)(jia)(jia)熱(re)(re)不(bu)同介(jie)質設計規范,按(an)照功(gong)率(lv)配(pei)置(zhi)要(yao)求裝配(pei)在法(fa)蘭蓋上,插入需加(jia)(jia)(jia)熱(re)(re)物料中,發熱(re)(re)元(yuan)(yuan)(yuan)件(jian)工(gong)作時(shi)(shi)所(suo)發出(chu)的大量(liang)熱(re)(re)量(liang)傳導給(gei)被加(jia)(jia)(jia)熱(re)(re)介(jie)質使(shi)介(jie)質溫(wen)(wen)度升高(gao),達到(dao)所(suo)需的工(gong)藝要(yao)求。當介(jie)質溫(wen)(wen)度達到(dao)工(gong)藝要(yao)求的設定(ding)值時(shi)(shi),控(kong)制系統(tong)根據(ju)溫(wen)(wen)度傳感器(qi)信號,經PID 運算(suan)后調節(jie)電(dian)(dian)加(jia)(jia)(jia)熱(re)(re)器(qi)輸出(chu)功(gong)率(lv),對(dui)發熱(re)(re)元(yuan)(yuan)(yuan)件(jian)的電(dian)(dian)阻性負載(zai)實(shi)現溫(wen)(wen)度控(kong)制。使(shi)介(jie)質溫(wen)(wen)度均勻,達到(dao)所(suo)需要(yao)求;當發熱(re)(re)元(yuan)(yuan)(yuan)件(jian)超溫(wen)(wen)或(huo)低液位時(shi)(shi),發熱(re)(re)元(yuan)(yuan)(yuan)件(jian)的聯(lian)鎖保(bao)護裝置(zhi)立即切斷加(jia)(jia)(jia)熱(re)(re)電(dian)(dian)源避免發熱(re)(re)元(yuan)(yuan)(yuan)件(jian)燒壞,延長使(shi)用壽命。
