防爆法蘭電熱器性能及使用
法蘭加熱(re)器是(shi)由多支加熱(re)管焊(han)接在法蘭上集(ji)中(zhong)加熱(re)。主(zhu)要用于敞開式、封閉式的溶(rong)液箱和循環系統中(zhong)加熱(re)用。
防爆法蘭電熱器優點
防爆法(fa)蘭電熱(re)(re)管(guan)(guan)表(biao)面(mian)功率(lv)大,使(shi)空氣加熱(re)(re)表(biao)面(mian)負荷的(de)(de)2~4倍,高度密集(ji)式、結構(gou)緊(jin)湊。由于整體短而密集(ji),故(gu)穩定性(xing)好,安裝無(wu)需(xu)支架。 組合式法(fa)蘭加熱(re)(re)器大多(duo)采用(yong)(yong)(yong)氬弧(hu)焊接(jie)(jie)方(fang)式使(shi)電熱(re)(re)管(guan)(guan)于法(fa)蘭連接(jie)(jie),也(ye)可利(li)用(yong)(yong)(yong)緊(jin)固(gu)裝置的(de)(de)形(xing)式,即每支電熱(re)(re)管(guan)(guan)上(shang)焊由緊(jin)固(gu)件(jian)。然(ran)后(hou)與法(fa)蘭蓋采用(yong)(yong)(yong)螺母鎖緊(jin)。管(guan)(guan)子于緊(jin)固(gu)件(jian)采用(yong)(yong)(yong)氬弧(hu)焊接(jie)(jie),永(yong)不泄(xie)漏。緊(jin)固(gu)件(jian)密封(feng)處采用(yong)(yong)(yong)科學(xue)的(de)(de)工(gong)藝。單(dan)支更換極為(wei)方(fang)便,大大節約以后(hou)的(de)(de)維修成本 選擇進(jin)口及國內優(you)質(zhi)材料。科學(xue)的(de)(de)生產工(gong)藝,嚴格的(de)(de)質(zhi)量管(guan)(guan)理,保(bao)證(zheng)電熱(re)(re)管(guan)(guan)優(you)越的(de)(de)電氣性(xing)能(neng)。
防爆法蘭電熱器概述及工作原理
法蘭加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器:是采(cai)用U型管狀(zhuang)電熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian),依據加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)不(bu)同介質(zhi)(zhi)設(she)(she)計規范,按照功(gong)率(lv)配置要(yao)(yao)求(qiu)裝配在法蘭蓋上(shang),插入需加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)物(wu)料中(zhong),發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)工作時(shi)所發(fa)出(chu)的大量熱(re)(re)(re)(re)(re)量傳導給被加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)介質(zhi)(zhi)使(shi)介質(zhi)(zhi)溫(wen)度升高,達到所需的工藝要(yao)(yao)求(qiu)。當介質(zhi)(zhi)溫(wen)度達到工藝要(yao)(yao)求(qiu)的設(she)(she)定值時(shi),控(kong)制系統根據溫(wen)度傳感器信號,經PID 運算后調節(jie)電加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器輸出(chu)功(gong)率(lv),對(dui)發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)的電阻性(xing)負載實現(xian)溫(wen)度控(kong)制。使(shi)介質(zhi)(zhi)溫(wen)度均勻,達到所需要(yao)(yao)求(qiu);當發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)超(chao)溫(wen)或低液位時(shi),發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)的聯鎖保護裝置立即(ji)切斷(duan)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)電源避免發(fa)熱(re)(re)(re)(re)(re)元(yuan)(yuan)(yuan)件(jian)燒壞,延長使(shi)用壽(shou)命(ming)。
