防爆法蘭電熱器性能及使用
法(fa)蘭加(jia)熱(re)(re)器是(shi)由多支加(jia)熱(re)(re)管焊接在法(fa)蘭上集中加(jia)熱(re)(re)。主要用(yong)于敞開式、封閉式的溶液箱和循環(huan)系統(tong)中加(jia)熱(re)(re)用(yong)。
防爆法蘭電熱器優點
防爆法(fa)蘭(lan)電(dian)(dian)熱(re)管(guan)(guan)表(biao)面功率大(da),使(shi)空氣(qi)加熱(re)表(biao)面負(fu)荷的(de)(de)2~4倍,高度密集(ji)(ji)式(shi)、結構(gou)緊湊。由于(yu)(yu)整體(ti)短而密集(ji)(ji),故(gu)穩(wen)定性(xing)好,安裝(zhuang)無需(xu)支(zhi)架(jia)。 組合式(shi)法(fa)蘭(lan)加熱(re)器(qi)大(da)多采(cai)用(yong)氬(ya)弧焊(han)接(jie)方式(shi)使(shi)電(dian)(dian)熱(re)管(guan)(guan)于(yu)(yu)法(fa)蘭(lan)連接(jie),也可利用(yong)緊固(gu)裝(zhuang)置的(de)(de)形(xing)式(shi),即每支(zhi)電(dian)(dian)熱(re)管(guan)(guan)上焊(han)由緊固(gu)件(jian)。然后(hou)與法(fa)蘭(lan)蓋采(cai)用(yong)螺母鎖緊。管(guan)(guan)子于(yu)(yu)緊固(gu)件(jian)采(cai)用(yong)氬(ya)弧焊(han)接(jie),永不泄(xie)漏。緊固(gu)件(jian)密封處(chu)采(cai)用(yong)科(ke)學(xue)的(de)(de)工(gong)藝。單(dan)支(zhi)更換極(ji)為方便,大(da)大(da)節約以后(hou)的(de)(de)維修成本 選擇進口及國內優(you)質(zhi)材(cai)料。科(ke)學(xue)的(de)(de)生產工(gong)藝,嚴(yan)格的(de)(de)質(zhi)量(liang)管(guan)(guan)理,保證電(dian)(dian)熱(re)管(guan)(guan)優(you)越的(de)(de)電(dian)(dian)氣(qi)性(xing)能。
防爆法蘭電熱器概述及工作原理
法蘭(lan)加(jia)熱(re)(re)(re)(re)器(qi):是(shi)采用(yong)U型管狀電熱(re)(re)(re)(re)元(yuan)件(jian)(jian),依據加(jia)熱(re)(re)(re)(re)不(bu)同介(jie)質(zhi)設計規范,按照(zhao)功率配(pei)置要(yao)(yao)求裝配(pei)在法蘭(lan)蓋上,插入(ru)需(xu)加(jia)熱(re)(re)(re)(re)物料中,發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)工作時所發(fa)(fa)出(chu)的大量熱(re)(re)(re)(re)量傳(chuan)導給(gei)被加(jia)熱(re)(re)(re)(re)介(jie)質(zhi)使(shi)介(jie)質(zhi)溫(wen)度(du)(du)升高(gao),達(da)到(dao)(dao)所需(xu)的工藝要(yao)(yao)求。當(dang)介(jie)質(zhi)溫(wen)度(du)(du)達(da)到(dao)(dao)工藝要(yao)(yao)求的設定(ding)值時,控制系統根據溫(wen)度(du)(du)傳(chuan)感器(qi)信號,經PID 運算(suan)后調節電加(jia)熱(re)(re)(re)(re)器(qi)輸(shu)出(chu)功率,對(dui)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的電阻(zu)性負(fu)載(zai)實(shi)現溫(wen)度(du)(du)控制。使(shi)介(jie)質(zhi)溫(wen)度(du)(du)均勻,達(da)到(dao)(dao)所需(xu)要(yao)(yao)求;當(dang)發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)超溫(wen)或低液位時,發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)的聯鎖保護裝置立即切斷(duan)加(jia)熱(re)(re)(re)(re)電源避(bi)免發(fa)(fa)熱(re)(re)(re)(re)元(yuan)件(jian)(jian)燒(shao)壞,延長(chang)使(shi)用(yong)壽(shou)命(ming)。
