法蘭電加熱管也稱插入式電加熱器
法蘭電加熱管性能及使用
法蘭加熱器是(shi)由(you)多(duo)支加熱管焊接(jie)在法蘭上集(ji)中加熱。主要用于敞開式、封閉(bi)式的溶液箱(xiang)和循(xun)環系統(tong)中加熱用。

表面(mian)功率大(da)(da)(da),使(shi)空氣(qi)加熱(re)表面(mian)負荷(he)的2~4倍,高度密(mi)集(ji)式(shi)、結構緊(jin)湊(cou)。由(you)于(yu)整體短而密(mi)集(ji),法(fa)蘭電(dian)(dian)加熱(re)管(guan)故(gu)穩(wen)定性好,安裝(zhuang)無需支(zhi)架。 組合式(shi)法(fa)蘭加熱(re)器(qi)大(da)(da)(da)多采(cai)用(yong)(yong)氬弧焊(han)接(jie)(jie)方式(shi)使(shi)電(dian)(dian)熱(re)管(guan)于(yu)法(fa)蘭連接(jie)(jie),也(ye)可(ke)利用(yong)(yong)緊(jin)固(gu)裝(zhuang)置的形式(shi),即每支(zhi)電(dian)(dian)熱(re)管(guan)上焊(han)由(you)緊(jin)固(gu)件。然后與法(fa)蘭蓋采(cai)用(yong)(yong)螺母(mu)鎖緊(jin)。管(guan)子于(yu)緊(jin)固(gu)件采(cai)用(yong)(yong)氬弧焊(han)接(jie)(jie),永不泄漏。緊(jin)固(gu)件密(mi)封處(chu)采(cai)用(yong)(yong)科(ke)學的工藝。單支(zhi)更換極為(wei)方便(bian),大(da)(da)(da)大(da)(da)(da)節(jie)約以后的維修(xiu)成本 選擇進口及(ji)國內優質(zhi)材料。科(ke)學的生產工藝,嚴格的質(zhi)量管(guan)理,保證(zheng)電(dian)(dian)熱(re)管(guan)優越的電(dian)(dian)氣(qi)性能。
法蘭電加熱管概述及工作原理
法蘭(lan)加(jia)(jia)熱(re)(re)(re)器:是采(cai)用U型管狀電熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件,依據加(jia)(jia)熱(re)(re)(re)不同介(jie)質(zhi)設計(ji)規范,按照功率(lv)配置要(yao)求(qiu)(qiu)裝配在法蘭(lan)蓋上(shang),插入需加(jia)(jia)熱(re)(re)(re)物(wu)料中,發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件工作時(shi)所發(fa)出的大量(liang)熱(re)(re)(re)量(liang)傳(chuan)導給被加(jia)(jia)熱(re)(re)(re)介(jie)質(zhi)使介(jie)質(zhi)溫(wen)(wen)(wen)(wen)度(du)升高,達到(dao)所需的工藝要(yao)求(qiu)(qiu)。當(dang)介(jie)質(zhi)溫(wen)(wen)(wen)(wen)度(du)達到(dao)工藝要(yao)求(qiu)(qiu)的設定值時(shi),控制(zhi)系統根據溫(wen)(wen)(wen)(wen)度(du)傳(chuan)感(gan)器信號,經PID 運算后調節(jie)電加(jia)(jia)熱(re)(re)(re)器輸(shu)出功率(lv),對(dui)發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件的電阻性負載(zai)實現溫(wen)(wen)(wen)(wen)度(du)控制(zhi)。使介(jie)質(zhi)溫(wen)(wen)(wen)(wen)度(du)均勻,達到(dao)所需要(yao)求(qiu)(qiu);當(dang)發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件超溫(wen)(wen)(wen)(wen)或(huo)低液位時(shi),發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件的聯鎖保護裝置立即切斷加(jia)(jia)熱(re)(re)(re)電源避免發(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)件燒壞,延長使用壽命(ming)。
