法蘭加熱器概況
法(fa)(fa)蘭電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)管(也稱插(cha)入式電(dian)(dian)(dian)(dian)(dian)加(jia)熱(re)(re)(re)器),是采用(yong)U型管狀(zhuang)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian),依據加(jia)熱(re)(re)(re)不同介(jie)質設計(ji)規范,按照(zhao)功率配(pei)置(zhi)要(yao)(yao)求(qiu)裝配(pei)在法(fa)(fa)蘭蓋上,插(cha)入需加(jia)熱(re)(re)(re)物(wu)料中,發(fa)(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)工(gong)作時所發(fa)(fa)出的(de)大量熱(re)(re)(re)量傳導給被加(jia)熱(re)(re)(re)介(jie)質使(shi)介(jie)質溫(wen)(wen)度升(sheng)高,達(da)到所需的(de)工(gong)藝(yi)要(yao)(yao)求(qiu)。當介(jie)質溫(wen)(wen)度達(da)到工(gong)藝(yi)要(yao)(yao)求(qiu)的(de)設定值時,控制系統根(gen)據溫(wen)(wen)度傳感器信號,經PID運算后調(diao)節電(dian)(dian)(dian)(dian)(dian)加(jia)熱(re)(re)(re)器輸出功率,對發(fa)(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的(de)電(dian)(dian)(dian)(dian)(dian)阻性負載實(shi)現溫(wen)(wen)度控制。使(shi)介(jie)質溫(wen)(wen)度均勻,達(da)到所需要(yao)(yao)求(qiu);當發(fa)(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)超(chao)溫(wen)(wen)或(huo)低液(ye)位時,發(fa)(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)的(de)聯鎖保護裝置(zhi)立即切斷加(jia)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)源避免發(fa)(fa)熱(re)(re)(re)元(yuan)(yuan)(yuan)(yuan)(yuan)件(jian)(jian)燒(shao)壞,延(yan)長使(shi)用(yong)壽命。 法(fa)(fa)蘭電(dian)(dian)(dian)(dian)(dian)熱(re)(re)(re)管主(zhu)要(yao)(yao)針對石(shi)油、化(hua)工(gong)、食品、機(ji)械等行業各類儲罐、容器、油箱內物(wu)料保溫(wen)(wen)和(he)加(jia)熱(re)(re)(re)。連接方式可采用(yong)法(fa)(fa)蘭式或(huo)螺紋端面密(mi)封。
法蘭加熱器性能及使用
法(fa)蘭加(jia)(jia)熱器(qi)是由多支(zhi)加(jia)(jia)熱管(guan)焊(han)接在法(fa)蘭上集中加(jia)(jia)熱。主要用于敞開式(shi)、封閉式(shi)的(de)溶液箱和循環系(xi)統(tong)中加(jia)(jia)熱用。
法蘭加熱器優點
表面功率大,使空氣加熱表面負荷的2~4倍,高度密集式、結構緊湊。由于整體短而密集,法蘭電加熱管故穩定性好,安裝無需支架。 組合式法蘭加熱器大多采用氬弧焊接方式使電熱管于法蘭連接,也可利用緊固裝置的形式,即每支電熱管上焊由緊固件。然后與法蘭蓋采用螺母鎖緊。管子于緊固件采用氬弧焊接,永不泄漏。緊固件密封處采用科學的工藝。單支更換極為方便,大大節約以后的維修成本 選擇進口及國內優質材料。科學的生產工藝,嚴格的質量管理,保證電熱管優越的電氣性能。
