電加熱器是專門將(jiang)電能轉(zhuan)換為熱能的(de)電器(qi)元件，結(jie)構簡單、使用(yong)方便(bian)、機械強度高、熱效率(lv)高、加熱速度快、可靠、安裝簡便(bian)、控制精度高、使用(yong)壽命長（一(yi)般(ban)設計(ji)使用(yong)壽命為10000個小時(shi)）等特點(dian)。廣(guang)泛適用(yong)于(yu)各種酸(suan)堿(jian)槽、水(shui)槽、油槽、空氣加熱爐、干(gan)燥箱、熱壓(ya)模等工(gong)況的(de)加熱。

電加熱器是一種消(xiao)耗(hao)電(dian)(dian)(dian)能(neng)轉換(huan)為熱(re)(re)(re)(re)(re)能(neng)，來(lai)對需加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)物(wu)料進行加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)。在(zai)工(gong)作(zuo)中低溫(wen)(wen)(wen)流(liu)(liu)體(ti)(ti)介質通過管(guan)道在(zai)壓力作(zuo)用下進入其輸(shu)(shu)入口，沿著(zhu)電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)容器(qi)(qi)(qi)內部(bu)特定換(huan)熱(re)(re)(re)(re)(re)流(liu)(liu)道，運用流(liu)(liu)體(ti)(ti)熱(re)(re)(re)(re)(re)力學原理設計的(de)路徑，帶走電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)元(yuan)件工(gong)作(zuo)中所產(chan)生的(de)高(gao)溫(wen)(wen)(wen)熱(re)(re)(re)(re)(re)能(neng)量，使(shi)被加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)介質溫(wen)(wen)(wen)度(du)升高(gao)，電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)出口得到工(gong)藝要求的(de)高(gao)溫(wen)(wen)(wen)介質。電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)內部(bu)控制系統依據輸(shu)(shu)出口的(de)溫(wen)(wen)(wen)度(du)傳感器(qi)(qi)(qi)信號自動調(diao)節電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)輸(shu)(shu)出功率，使(shi)輸(shu)(shu)出口的(de)介質溫(wen)(wen)(wen)度(du)均勻(yun);當發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)件超(chao)溫(wen)(wen)(wen)時，發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)件的(de)獨立的(de)過熱(re)(re)(re)(re)(re)保(bao)護裝置立即(ji)切(qie)斷加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)電(dian)(dian)(dian)源，避免(mian)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)物(wu)料超(chao)溫(wen)(wen)(wen)引起結焦、變質、碳化，嚴重時導致發(fa)(fa)熱(re)(re)(re)(re)(re)元(yuan)件燒(shao)壞(huai)，有效(xiao)延長(chang)電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)使(shi)用壽命。
