防爆法蘭電熱器性能及使用
法蘭加熱(re)(re)器是由多支加熱(re)(re)管焊(han)接在法蘭上集中加熱(re)(re)。主要用(yong)于敞開(kai)式、封閉式的溶液箱和循(xun)環系(xi)統中加熱(re)(re)用(yong)。
防爆法蘭電熱器優點
防(fang)爆法蘭電(dian)(dian)(dian)熱(re)管表面(mian)功(gong)率大,使(shi)空(kong)氣加熱(re)表面(mian)負(fu)荷的2~4倍(bei),高度密集式、結構緊(jin)湊。由于整體(ti)短而密集,故(gu)穩(wen)定性好,安裝無需(xu)支架。 組(zu)合(he)式法蘭加熱(re)器大多(duo)采(cai)(cai)用氬弧焊接(jie)方式使(shi)電(dian)(dian)(dian)熱(re)管于法蘭連接(jie),也可(ke)利用緊(jin)固(gu)(gu)裝置的形式,即(ji)每支電(dian)(dian)(dian)熱(re)管上(shang)焊由緊(jin)固(gu)(gu)件。然后(hou)與法蘭蓋采(cai)(cai)用螺母鎖緊(jin)。管子(zi)于緊(jin)固(gu)(gu)件采(cai)(cai)用氬弧焊接(jie),永(yong)不泄漏。緊(jin)固(gu)(gu)件密封處采(cai)(cai)用科學(xue)的工(gong)(gong)藝。單支更換極為方便,大大節(jie)約(yue)以后(hou)的維修成本 選擇進口及(ji)國內優質(zhi)材料。科學(xue)的生產工(gong)(gong)藝,嚴格(ge)的質(zhi)量管理(li),保證電(dian)(dian)(dian)熱(re)管優越的電(dian)(dian)(dian)氣性能。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)熱(re)(re)(re)(re)器:是采用(yong)U型(xing)管狀電(dian)(dian)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian),依據加(jia)熱(re)(re)(re)(re)不同介(jie)質(zhi)設計規范,按(an)照功率(lv)配(pei)置要求(qiu)(qiu)裝配(pei)在法蘭蓋上,插入需(xu)加(jia)熱(re)(re)(re)(re)物料中(zhong),發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)工作時(shi)所發(fa)(fa)出的(de)大量熱(re)(re)(re)(re)量傳(chuan)導(dao)給被(bei)加(jia)熱(re)(re)(re)(re)介(jie)質(zhi)使(shi)介(jie)質(zhi)溫(wen)(wen)度(du)(du)升(sheng)高,達到所需(xu)的(de)工藝(yi)要求(qiu)(qiu)。當介(jie)質(zhi)溫(wen)(wen)度(du)(du)達到工藝(yi)要求(qiu)(qiu)的(de)設定值時(shi),控(kong)制(zhi)系統根據溫(wen)(wen)度(du)(du)傳(chuan)感器信號(hao),經(jing)PID 運算后調節電(dian)(dian)加(jia)熱(re)(re)(re)(re)器輸出功率(lv),對發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)的(de)電(dian)(dian)阻(zu)性負載(zai)實(shi)現溫(wen)(wen)度(du)(du)控(kong)制(zhi)。使(shi)介(jie)質(zhi)溫(wen)(wen)度(du)(du)均(jun)勻(yun),達到所需(xu)要求(qiu)(qiu);當發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)超溫(wen)(wen)或低液(ye)位時(shi),發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)的(de)聯鎖保護裝置立即(ji)切斷加(jia)熱(re)(re)(re)(re)電(dian)(dian)源避免發(fa)(fa)熱(re)(re)(re)(re)元(yuan)(yuan)件(jian)燒壞(huai),延長使(shi)用(yong)壽命。
