普及下電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱器的應用原理,電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱是將(jiang)380V50Hz交流(liu)電(dian)(dian)(dian)(dian)變(bian)成(cheng)530VDC-560VDC50HZ直流(liu)電(dian)(dian)(dian)(dian),再(zai)經過變(bian)頻(pin)控制技(ji)術逆變(bian)成(cheng)5KHZ-30Hz的高頻(pin)交流(liu)電(dian)(dian)(dian)(dian)流(liu),通過電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱感應器與(yu)電(dian)(dian)(dian)(dian)磁(ci)線圈(quan)組合轉換為高頻(pin)交變(bian)磁(ci)場,交變(bian)磁(ci)場的磁(ci)力線作(zuo)用到金(jin)屬管(guan)道上產(chan)生(sheng)鍋(guo)流(liu),從而快速加(jia)(jia)熱金(jin)屬管(guan)道。
電(dian)磁加(jia)熱(re)(re)器(qi)(qi)的(de)(de)(de)(de)(de)溫(wen)度升不(bu)上(shang)去該怎么辦?第種(zhong)解決方法:當為注(zhu)塑機(ji)、吹(chui)膜機(ji)類似于小功(gong)率(lv)時(shi)(shi),安裝電(dian)磁加(jia)熱(re)(re)器(qi)(qi)后有些(xie)機(ji)器(qi)(qi)溫(wen)度總是(shi)(shi)(shi)差(cha)點點。然后有的(de)(de)(de)(de)(de)客戶就(jiu)把功(gong)率(lv)調(diao)節大(da)些(xie)還是(shi)(shi)(shi)樣(yang),有的(de)(de)(de)(de)(de)客戶還干脆(cui)就(jiu)把溫(wen)度直接設定(ding)調(diao)高,大(da)家(jia)都覺(jue)得很奇怪,有時(shi)(shi)候總感覺(jue)就(jiu)是(shi)(shi)(shi)看不(bu)懂,摸不(bu)著頭腦。其實呢,這(zhe)個大(da)多(duo)數(shu)的(de)(de)(de)(de)(de)原因不(bu)是(shi)(shi)(shi)功(gong)率(lv)安裝小,而且(qie)由于原來(lai)機(ji)器(qi)(qi)的(de)(de)(de)(de)(de)溫(wen)控制器(qi)(qi)輸出的(de)(de)(de)(de)(de)PID運算(suan)方法引起來(lai)的(de)(de)(de)(de)(de),啟(qi)動信號很短,有些(xie)短到1-5秒(miao)以(yi)內,電(dian)磁加(jia)熱(re)(re)器(qi)(qi)都還沒有來(lai)得及開始工作,就(jiu)又斷了。所以(yi)導致電(dian)磁加(jia)熱(re)(re)器(qi)(qi)大(da)多(duo)數(shu)時(shi)(shi)間處于停止狀態,基(ji)本上(shang)是(shi)(shi)(shi)沒有在加(jia)熱(re)(re)的(de)(de)(de)(de)(de)。因為加(jia)熱(re)(re)的(de)(de)(de)(de)(de)溫(wen)度總是(shi)(shi)(shi)達(da)不(bu)到的(de)(de)(de)(de)(de)。這(zhe)時(shi)(shi)我們可以(yi)調(diao)節機(ji)器(qi)(qi)中的(de)(de)(de)(de)(de)斷開延時(shi)(shi)工作時(shi)(shi)間,來(lai)達(da)到溫(wen)度要求。詳細的(de)(de)(de)(de)(de)方法使(shi)用說(shuo)明書上(shang)也有,調(diao)節為8-15秒(miao),默(mo)認為0秒(miao),般為8秒(miao)鐘(zhong)就(jiu)可以(yi)實現沒有溫(wen)差(cha)了,但是(shi)(shi)(shi)得注(zhu)意哦,不(bu)要調(diao)節到太(tai)大(da),否則(ze)溫(wen)度可能會超的(de)(de)(de)(de)(de)。
電磁加熱(re)板的配件有哪些?2P排(pai)線(xian)、10K熱(re)敏電阻、吸收板1塊、風扇線(xian)、顯示盒、530V電源線(xian)(帶磁環)、高頻(pin)互感器。
電磁加熱控制器(qi)運用在反應釜上(shang)有什(shen)么(me)優勢呢?
、加熱(re)升溫時間(jian)短、能量轉換效(xiao)率(lv)高(gao),該設備采用就地電(dian)磁(ci)加熱(re),直接加熱(re)罐體(ti),減少中間(jian)熱(re)傳遞過程(cheng)提高(gao)熱(re)效(xiao)率(lv)利用。
二、安(an)裝方便(bian),次性投入(ru)成本低,只在原(yuan)反應(ying)(ying)釜加入(ru)電磁(ci)感應(ying)(ying)器即可,不對原(yuan)反應(ying)(ying)釜進行大量(liang)的(de)改造。
三、運行成本低,無(wu)(wu)需(xu)管道、鍋爐(lu)、煤場、智(zhi)能監控,真(zhen)正實現無(wu)(wu)人(ren)值(zhi)守。
四、軟啟動:無啟動沖擊電(dian)流(liu),可(ke)以有效保護設備不受傷害。
五(wu)、安全防爆、無(wu)明火。線圈溫度在100度以內(nei),加熱部分(fen)采用電纜室(shi)結構(gou),加熱電纜本(ben)身不(bu)會(hui)產生熱量。
六、升(sheng)溫速度快,溫度高,高可達(da)600度加(jia)熱(re)時,加(jia)熱(re)介質(zhi)與(yu)電分離(li),感應器本身(shen)不(bu)產(chan)生高溫,不(bu)產(chan)生火花(hua),電源(yuan)采用特殊(shu)的防爆外殼。
七、綠色環保,無任何廢棄物產(chan)生,符合可持續發(fa)展(zhan)戰略(lve)。
在使用電(dian)磁加熱器時要注意什么?
1、使(shi)用程要(yao)輕易拆除(chu)電磁加熱控制板接導線接措(cuo)施防止觸(chu)電道保護措(cuo)施。
2、要定期清理散(san)熱器(qi)保(bao)證(zheng)電磷感應加熱器(qi)通風。
3、使用電(dian)磁加熱器應先按說明書繞線圈并檢(jian)查(cha)誤再接(jie)通電(dian)源(yuan)。
4、保養清洗(xi)電(dian)磁加熱器(qi)(qi)前(qian)切斷電(dian)磁加熱器(qi)(qi)電(dian)源清潔電(dian)磁加熱器(qi)(qi)外殼應用(yong)干凈抹布進行擦(ca)拭嚴(yan)禁用(yong)噴射水流沖洗(xi)外殼及電(dian)器(qi)(qi)箱部。
5、要電(dian)磁加(jia)熱器安裝潮(chao)濕環境防止(zhi)水蒸(zheng)汽進入電(dian)箱易緣介質(zhi)表面凝結降(jiang)低其緣性能造漏電(dian)事(shi)故(gu)。
6、要經(jing)檢查電(dian)磁加熱器進風(feng)口及散(san)熱風(feng)扇防止進風(feng)口處堵(du)塞或散(san)熱風(feng)扇卡死避免熱停機保護。
電(dian)磁加熱器不工(gong)作的十大(da)因素:
1、電磁加熱(re)器內部受潮,線路損壞,導(dao)致電磁加熱(re)器不(bu)工作。
2、電壓(ya):電壓(ya)應(ying)該高于323V并且低(di)于440V,否(fou)則就容(rong)易啟(qi)動不了機器(qi)。
3、線(xian)圈溫(wen)度(du)過高:檢查(cha)線(xian)圈的(de)溫(wen)度(du)或者是(shi)先去溫(wen)度(du)傳感(gan)(gan)器的(de)情況。解決辦(ban)法是(shi)檢查(cha)散(san)熱風扇是(shi)否損壞(huai),接線(xian)頭是(shi)否良好,是(shi)否更(geng)換(huan)線(xian)圈溫(wen)度(du)傳感(gan)(gan)器。
4、IGBT溫(wen)度(du):檢查IGBT溫(wen)度(du)傳感器(qi)、連接(jie)線、IGBT溫(wen)度(du)。解決(jue)辦法是散(san)熱(re)扇是否(fou)正(zheng)常工作,是否(fou)更(geng)換IGBT溫(wen)度(du)傳感器(qi)。
5、負載:檢查(cha)線(xian)圈鏈接、電感參數、IGBT驅動板(ban)和(he)線(xian)。解決(jue)辦法是線(xian)圈圈數是否纏繞圈數過(guo)多或者過(guo)少(shao),測試(shi)IGBT驅動板(ban)和(he)檢查(cha)IGBT線(xian)。
6、通訊異常:檢(jian)查通訊鏈接(jie)線鏈接(jie)、控制(zhi)板和AI板。解(jie)決辦(ban)法(fa)更換(huan)控制(zhi)板或者AI板。
7、IGBT模塊使用時(shi)間(jian)太長(chang),導(dao)致IGBT模塊老化開裂,使電磁加熱器不能工作。
8、電(dian)磁加熱器內部電(dian)子元件規劃不合理,導致電(dian)磁加熱器不工作(zuo)。
9、電(dian)磁加(jia)熱(re)器抗干擾性差(cha),導致不能正(zheng)常工作。
10、因(yin)為線路(lu)短路(lu)、漏電、超(chao)負荷、開(kai)關損壞導致跳(tiao)閘使電磁加熱器不(bu)能正常工作。
