防爆法蘭電熱器性能及使用
法蘭(lan)加(jia)熱器(qi)是由(you)多支加(jia)熱管焊接(jie)在法蘭(lan)上集中(zhong)加(jia)熱。主要(yao)用于敞開(kai)式、封閉式的溶(rong)液箱和(he)循環系統中(zhong)加(jia)熱用。
防爆法蘭電熱器優點
防爆(bao)法(fa)蘭(lan)電(dian)(dian)熱(re)管(guan)表面功率大(da)(da),使空氣加(jia)(jia)熱(re)表面負荷(he)的2~4倍,高度(du)密集式、結構緊(jin)(jin)湊。由(you)于(yu)整體短而密集,故穩定(ding)性好,安(an)裝無需支架。 組合(he)式法(fa)蘭(lan)加(jia)(jia)熱(re)器大(da)(da)多采用(yong)(yong)氬弧(hu)焊接(jie)方(fang)式使電(dian)(dian)熱(re)管(guan)于(yu)法(fa)蘭(lan)連接(jie),也可利(li)用(yong)(yong)緊(jin)(jin)固(gu)(gu)(gu)裝置的形式,即每支電(dian)(dian)熱(re)管(guan)上焊由(you)緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)。然后(hou)與法(fa)蘭(lan)蓋采用(yong)(yong)螺(luo)母(mu)鎖緊(jin)(jin)。管(guan)子于(yu)緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)采用(yong)(yong)氬弧(hu)焊接(jie),永不泄漏。緊(jin)(jin)固(gu)(gu)(gu)件(jian)(jian)密封處采用(yong)(yong)科(ke)學(xue)的工(gong)藝。單(dan)支更換極為方(fang)便(bian),大(da)(da)大(da)(da)節約以后(hou)的維(wei)修成本(ben) 選擇進口及國(guo)內(nei)優(you)質(zhi)材料。科(ke)學(xue)的生產工(gong)藝,嚴格的質(zhi)量管(guan)理,保證電(dian)(dian)熱(re)管(guan)優(you)越(yue)的電(dian)(dian)氣性能。
防爆法蘭電熱器概述及工作原理
法(fa)(fa)蘭(lan)加(jia)(jia)熱(re)(re)(re)器(qi):是(shi)采用U型管(guan)狀電(dian)(dian)熱(re)(re)(re)元(yuan)件,依(yi)據(ju)加(jia)(jia)熱(re)(re)(re)不同介(jie)(jie)質(zhi)(zhi)設(she)計規范,按照功率(lv)配置要求(qiu)(qiu)裝配在法(fa)(fa)蘭(lan)蓋上(shang),插入需加(jia)(jia)熱(re)(re)(re)物(wu)料中,發(fa)(fa)熱(re)(re)(re)元(yuan)件工(gong)作時所發(fa)(fa)出(chu)的大量熱(re)(re)(re)量傳(chuan)導給被加(jia)(jia)熱(re)(re)(re)介(jie)(jie)質(zhi)(zhi)使(shi)介(jie)(jie)質(zhi)(zhi)溫度(du)升(sheng)高,達到所需的工(gong)藝要求(qiu)(qiu)。當介(jie)(jie)質(zhi)(zhi)溫度(du)達到工(gong)藝要求(qiu)(qiu)的設(she)定值時,控制(zhi)系統根據(ju)溫度(du)傳(chuan)感器(qi)信號,經(jing)PID 運算(suan)后(hou)調節電(dian)(dian)加(jia)(jia)熱(re)(re)(re)器(qi)輸(shu)出(chu)功率(lv),對發(fa)(fa)熱(re)(re)(re)元(yuan)件的電(dian)(dian)阻性(xing)負(fu)載實(shi)現溫度(du)控制(zhi)。使(shi)介(jie)(jie)質(zhi)(zhi)溫度(du)均(jun)勻,達到所需要求(qiu)(qiu);當發(fa)(fa)熱(re)(re)(re)元(yuan)件超溫或低液位時,發(fa)(fa)熱(re)(re)(re)元(yuan)件的聯鎖保護裝置立即切(qie)斷加(jia)(jia)熱(re)(re)(re)電(dian)(dian)源(yuan)避免發(fa)(fa)熱(re)(re)(re)元(yuan)件燒壞,延(yan)長(chang)使(shi)用壽命。
