防爆法蘭電熱器性能及使用
法(fa)蘭(lan)加(jia)熱器(qi)是(shi)由多(duo)支(zhi)加(jia)熱管焊接在法(fa)蘭(lan)上(shang)集(ji)中(zhong)加(jia)熱。主要用(yong)于(yu)敞開式、封(feng)閉(bi)式的溶液箱和循環(huan)系統中(zhong)加(jia)熱用(yong)。
防爆法蘭電熱器優點
防爆法(fa)蘭電(dian)熱管(guan)(guan)表(biao)面(mian)功率大,使空氣(qi)(qi)加熱表(biao)面(mian)負荷的(de)2~4倍,高度密集(ji)式(shi)(shi)、結(jie)構(gou)緊(jin)湊。由于整體短而密集(ji),故穩定(ding)性(xing)好(hao),安裝無需支架。 組(zu)合式(shi)(shi)法(fa)蘭加熱器大多采(cai)(cai)用(yong)(yong)(yong)氬弧焊接方式(shi)(shi)使電(dian)熱管(guan)(guan)于法(fa)蘭連接,也(ye)可利用(yong)(yong)(yong)緊(jin)固(gu)(gu)裝置的(de)形式(shi)(shi),即每(mei)支電(dian)熱管(guan)(guan)上焊由緊(jin)固(gu)(gu)件(jian)。然后(hou)與法(fa)蘭蓋采(cai)(cai)用(yong)(yong)(yong)螺母鎖緊(jin)。管(guan)(guan)子于緊(jin)固(gu)(gu)件(jian)采(cai)(cai)用(yong)(yong)(yong)氬弧焊接,永不(bu)泄(xie)漏。緊(jin)固(gu)(gu)件(jian)密封處采(cai)(cai)用(yong)(yong)(yong)科(ke)學(xue)的(de)工(gong)藝(yi)。單支更(geng)換極為方便(bian),大大節約(yue)以后(hou)的(de)維修成本 選(xuan)擇進口及(ji)國內優(you)質(zhi)材料。科(ke)學(xue)的(de)生產工(gong)藝(yi),嚴格的(de)質(zhi)量管(guan)(guan)理,保證電(dian)熱管(guan)(guan)優(you)越的(de)電(dian)氣(qi)(qi)性(xing)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)(re)器:是采用U型管狀電(dian)熱(re)(re)(re)元(yuan)件(jian)(jian),依(yi)據(ju)加(jia)(jia)(jia)熱(re)(re)(re)不(bu)同(tong)介(jie)質設(she)(she)計規范,按照功率(lv)配置要(yao)(yao)求(qiu)裝配在(zai)法(fa)蘭蓋上,插入需加(jia)(jia)(jia)熱(re)(re)(re)物(wu)料中(zhong),發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)工(gong)作時所(suo)(suo)發(fa)出(chu)的(de)(de)(de)大量熱(re)(re)(re)量傳導(dao)給被加(jia)(jia)(jia)熱(re)(re)(re)介(jie)質使介(jie)質溫度升高,達(da)到所(suo)(suo)需的(de)(de)(de)工(gong)藝要(yao)(yao)求(qiu)。當介(jie)質溫度達(da)到工(gong)藝要(yao)(yao)求(qiu)的(de)(de)(de)設(she)(she)定(ding)值時,控(kong)制系統根據(ju)溫度傳感器信號,經(jing)PID 運算后調(diao)節電(dian)加(jia)(jia)(jia)熱(re)(re)(re)器輸出(chu)功率(lv),對發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)的(de)(de)(de)電(dian)阻(zu)性負載實現(xian)溫度控(kong)制。使介(jie)質溫度均(jun)勻,達(da)到所(suo)(suo)需要(yao)(yao)求(qiu);當發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)超溫或低(di)液位時,發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)的(de)(de)(de)聯鎖(suo)保(bao)護裝置立即(ji)切斷加(jia)(jia)(jia)熱(re)(re)(re)電(dian)源避免發(fa)熱(re)(re)(re)元(yuan)件(jian)(jian)燒壞(huai),延(yan)長使用壽命。
