法(fa)蘭電(dian)加(jia)熱器(qi)性能(neng)及使用
法(fa)(fa)蘭(lan)加熱器是由多支加熱管(guan)焊接在(zai)法(fa)(fa)蘭(lan)上集中(zhong)加熱。主要用于敞開式、封(feng)閉(bi)式的溶液箱(xiang)和循(xun)環系統(tong)中(zhong)加熱用。
法蘭電加熱器優點(dian)
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。
