法蘭(lan)加(jia)(jia)熱(re)(re)管(guan)(也稱插入(ru)式(shi)電(dian)(dian)加(jia)(jia)熱(re)(re)器):是采用U型管(guan)狀電(dian)(dian)熱(re)(re)元(yuan)(yuan)件，依據加(jia)(jia)熱(re)(re)不(bu)同介質設(she)計規范，按照功率配(pei)置(zhi)要(yao)求(qiu)裝配(pei)在法蘭(lan)蓋上，插入(ru)需(xu)加(jia)(jia)熱(re)(re)物料中(zhong)，發(fa)(fa)熱(re)(re)元(yuan)(yuan)件工(gong)作(zuo)時所發(fa)(fa)出的(de)大(da)量熱(re)(re)量傳導給被加(jia)(jia)熱(re)(re)介質使(shi)(shi)介質溫(wen)(wen)度(du)升高(gao)，達(da)到(dao)所需(xu)的(de)工(gong)藝要(yao)求(qiu)。當介質溫(wen)(wen)度(du)達(da)到(dao)工(gong)藝要(yao)求(qiu)的(de)設(she)定(ding)值(zhi)時控制(zhi)系統(tong)根據溫(wen)(wen)度(du)傳感器信號，經PID運算后調節電(dian)(dian)加(jia)(jia)熱(re)(re)器輸(shu)出功率，對發(fa)(fa)熱(re)(re)元(yuan)(yuan)件的(de)電(dian)(dian)阻性負(fu)載實現溫(wen)(wen)度(du)控制(zhi)。使(shi)(shi)介質溫(wen)(wen)度(du)均勻，達(da)到(dao)所需(xu)要(yao)求(qiu);當發(fa)(fa)熱(re)(re)元(yuan)(yuan)件超溫(wen)(wen)或低液位(wei)時，發(fa)(fa)熱(re)(re)元(yuan)(yuan)件的(de)聯鎖(suo)保護裝置(zhi)立即(ji)切(qie)斷加(jia)(jia)熱(re)(re)電(dian)(dian)源避免(mian)發(fa)(fa)熱(re)(re)元(yuan)(yuan)件燒壞，延長使(shi)(shi)用壽(shou)命(ming)。

產品特點

法蘭加(jia)熱管表面功率大，是(shi)空氣加(jia)熱表面負荷的2~4倍高度(du)密集(ji)式(shi)(shi)、結構緊湊。由(you)于(yu)(yu)整體短而密集(ji)，故(gu)穩定性好，安(an)裝無需支(zhi)架組合式(shi)(shi)大多采(cai)用(yong)(yong)氬弧焊接方(fang)式(shi)(shi)使電(dian)熱管于(yu)(yu)法蘭連接，也可利(li)用(yong)(yong)緊固裝置(zhi)的形式(shi)(shi)，即(ji)每支(zhi)電(dian)熱管上焊由(you)緊固件。然后與法蘭蓋(gai)采(cai)用(yong)(yong)螺母鎖緊。管子于(yu)(yu)緊固件采(cai)用(yong)(yong)氬弧焊接，緊固件密封處(chu)采(cai)用(yong)(yong)科學(xue)的工藝(yi)。單支(zhi)更換方(fang)便，節約以后的維修成本(ben)。
