電(dian)(dian)磁(ci)(ci)加(jia)熱(re)簡介：電(dian)(dian)磁(ci)(ci)加(jia)熱(re)也(ye)稱電(dian)(dian)磁(ci)(ci)感應加(jia)熱(re)，即(ji)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(外文:Electromagnetic heating縮寫(xie)：EH)技術(shu)，電(dian)(dian)磁(ci)(ci)加(jia)熱(re)的(de)原(yuan)理是通(tong)過電(dian)(dian)子(zi)(zi)線路板組成部(bu)(bu)分產(chan)生(sheng)交變(bian)磁(ci)(ci)場、當用(yong)含(han)鐵質(zhi)容(rong)(rong)器放(fang)置(zhi)上面(mian)時，容(rong)(rong)器表面(mian)即(ji)切(qie)割(ge)交變(bian)磁(ci)(ci)力線而在容(rong)(rong)器底部(bu)(bu)金屬部(bu)(bu)分產(chan)生(sheng)交變(bian)的(de)電(dian)(dian)流(liu)(liu)（即(ji)渦流(liu)(liu)），渦流(liu)(liu)使(shi)容(rong)(rong)器底部(bu)(bu)的(de)載流(liu)(liu)子(zi)(zi)高速無(wu)規則運動，載流(liu)(liu)子(zi)(zi)與原(yuan)子(zi)(zi)互相(xiang)碰(peng)撞、摩擦而產(chan)生(sheng)熱(re)能。從而起(qi)到(dao)加(jia)熱(re)物品(pin)的(de)效果。因為是鐵制容(rong)(rong)器自身發熱(re)，所以熱(re)轉化率特別(bie)高，高可達到(dao)95%是種直(zhi)接加(jia)熱(re)的(de)方式。電(dian)(dian)磁(ci)(ci)爐(lu)，電(dian)(dian)磁(ci)(ci)灶 電(dian)(dian)磁(ci)(ci)加(jia)熱(re)電(dian)(dian)飯鍋都(dou)是采用(yong)的(de)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)技術(shu)。

影(ying)響電磁加熱器(qi)質(zhi)量(liang)好(hao)壞的幾個原因：

1、材料因素(su)——電磁(ci)加熱(re)器因為(wei)是(shi)工(gong)業產品，所以(yi)元(yuan)器件的(de)(de)選材上(shang)，追(zhui)求的(de)(de)是(shi)持(chi)續(xu)、穩定(ding)的(de)(de)元(yuan)器件，好的(de)(de)電磁(ci)加熱(re)器價(jia)格上(shang)對高于，小廠所謂的(de)(de)普及品，流工(gong)廠做質量(liang)，二流工(gong)廠做價(jia)格。說簡單點(dian)大(da)(da)廠為(wei)了質量(liang)，選配(pei)元(yuan)器件上(shang)喜歡采(cai)用進(jin)口(kou)的(de)(de)好元(yuan)器件，個(ge)別時候可能(neng)因為(wei)讓設(she)備更長(chang)壽，采(cai)用遠超需要的(de)(de)元(yuan)器件，不(bu)讓元(yuan)器件滿(man)負荷工(gong)作，而小公司為(wei)了多賣(mai)機器，大(da)(da)多打著(zhu)便宜(yi)的(de)(de)口(kou)號，但便宜(yi)的(de)(de)價(jia)格來至于低廉的(de)(de)成本，低成本必然是(shi)低質量(liang)。

2、技(ji)術(shu)因素——電(dian)(dian)視機這(zhe)個(ge)成熟的(de)(de)(de)產(chan)品不(bu)同的(de)(de)(de)品還有(you)著好(hao)壞(huai)之分，何況(kuang)是(shi)電(dian)(dian)磁加(jia)熱這(zhe)個(ge)新(xin)興產(chan)業，有(you)的(de)(de)(de)廠家開廠好(hao)幾年了，有(you)的(de)(de)(de)廠家才(cai)兩年，如果說技(ji)術(shu)條件是(shi)樣的(de)(de)(de)，那是(shi)不(bu)可能(neng)(neng)的(de)(de)(de)，期(qi)間(jian)每個(ge)型號的(de)(de)(de)機器都有(you)技(ji)術(shu)性(xing)的(de)(de)(de)改(gai)動(dong)，改(gai)動(dong)多的(de)(de)(de)2.5kw的(de)(de)(de)電(dian)(dian)磁加(jia)熱器超(chao)過四次重新(xin)設計(ji)了，期(qi)間(jian)些小缺陷慢(man)(man)慢(man)(man)的(de)(de)(de)也修補完(wan)善，如果家新(xin)公司在(zai)沒有(you)產(chan)品大量市場(chang)反饋，單(dan)憑技(ji)術(shu)人員實(shi)驗是(shi)不(bu)可能(neng)(neng)做(zuo)出合適的(de)(de)(de)電(dian)(dian)磁加(jia)熱器的(de)(de)(de)，因為他(ta)們只懂(dong)電(dian)(dian)磁加(jia)熱器不(bu)懂(dong)塑料(liao)生產(chan)，不(bu)懂(dong)塑料(liao)機的(de)(de)(de)原(yuan)理。

3、經驗因素(su)——電(dian)(dian)磁加熱(re)器(qi)(qi)安(an)(an)裝的(de)(de)(de)好，和安(an)(an)裝的(de)(de)(de)不(bu)(bu)好效(xiao)果是(shi)很打(da)區別，這(zhe)(zhe)點需要豐富的(de)(de)(de)安(an)(an)裝實例(li)，光靠幾組(zu)數據是(shi)分析不(bu)(bu)出(chu)來的(de)(de)(de)，新公司根本沒有(you)這(zhe)(zhe)樣的(de)(de)(de)經驗來支撐，完全靠理(li)論在安(an)(an)裝。人家說臺(tai)同型號(hao)(hao)的(de)(de)(de)電(dian)(dian)磁加熱(re)器(qi)(qi)，裝在同型號(hao)(hao)的(de)(de)(de)注塑(su)機上(shang)，為什(shen)么個(ge)省電(dian)(dian)40%以上(shang)，個(ge)剛剛夠理(li)論數據的(de)(de)(de)30%，電(dian)(dian)磁感應加熱(re)器(qi)(qi)講解這(zhe)(zhe)不(bu)(bu)僅是(shi)機器(qi)(qi)的(de)(de)(de)差異(yi)，電(dian)(dian)磁加熱(re)器(qi)(qi)的(de)(de)(de)安(an)(an)裝位(wei)置，線(xian)圈長短都有(you)影響，如果是(shi)采用多組(zu)小功(gong)率的(de)(de)(de)電(dian)(dian)磁加熱(re)器(qi)(qi)，這(zhe)(zhe)個(ge)差異(yi)就(jiu)更(geng)為明(ming)顯。

電(dian)磁加(jia)(jia)熱器(qi)(qi)在(zai)油田管(guan)道中(zhong)的(de)(de)(de)應用(yong)：冬季由于(yu)野(ye)外氣溫(wen)(wen)較(jiao)低，在(zai)油由管(guan)道中(zhong)石油中(zhong)含(han)蠟(la)量(liang)高，管(guan)件容易(yi)凍堵。傳統的(de)(de)(de)方式是(shi)用(yong)火燒(shao)，但是(shi)用(yong)明火違反了(le)采(cai)油區(qu)禁止明火的(de)(de)(de)安全(quan)規定，易(yi)發(fa)生安全(quan)事故，電(dian)熱發(fa)熱板加(jia)(jia)熱又破壞了(le)原有的(de)(de)(de)保(bao)(bao)溫(wen)(wen)層(ceng)，且熱量(liang)散失大，速(su)度(du)漫，時間長(chang)，功耗大。用(yong)錯能電(dian)磁加(jia)(jia)熱器(qi)(qi)，機組(zu)磁力可以(yi)穿過(guo)保(bao)(bao)溫(wen)(wen)層(ceng)、纖維布等保(bao)(bao)溫(wen)(wen)材料(liao)以(yi)感應的(de)(de)(de)方式快(kuai)速(su)對管(guan)道自身(shen)加(jia)(jia)熱。

電磁加熱器高(gao)(gao)溫(wen)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)選(xuan)(xuan)擇(ze)：從(cong)高(gao)(gao)溫(wen)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)外包裝來看，高(gao)(gao)溫(wen)線(xian)(xian)(xian)(xian)般(ban)通過導體+纖(xian)編(bian)(bian)織+云母繞包+涂(tu)(tu)層的(de)(de)(de)(de)組合(he)而(er)成。但(dan)是根據需要的(de)(de)(de)(de)不同(tong)，會再添(tian)加玻纖(xian)編(bian)(bian)織和云母繞包，發生意外的(de)(de)(de)(de)幾率就能(neng)(neng)大大的(de)(de)(de)(de)減少。導體需要根據現場(chang)(chang)的(de)(de)(de)(de)情(qing)況(kuang)和工作的(de)(de)(de)(de)情(qing)況(kuang)選(xuan)(xuan)擇(ze)高(gao)(gao)溫(wen)線(xian)(xian)(xian)(xian)的(de)(de)(de)(de)材質是否進(jin)行電鍍，并且規格也(ye)有所(suo)(suo)選(xuan)(xuan)擇(ze)，根據現場(chang)(chang)安裝機械選(xuan)(xuan)擇(ze)0.1mm2-0.3mm2的(de)(de)(de)(de)線(xian)(xian)(xian)(xian)徑，線(xian)(xian)(xian)(xian)徑越(yue)粗，相對(dui)來說(shuo)再繞制高(gao)(gao)線(xian)(xian)(xian)(xian)時越(yue)容(rong)(rong)易固定，但(dan)是不容(rong)(rong)易扭(niu)動；而(er)線(xian)(xian)(xian)(xian)徑細(xi)的(de)(de)(de)(de)繞線(xian)(xian)(xian)(xian)比較松散(san)，所(suo)(suo)以(yi)般(ban)是考慮繞制方便時采(cai)用。而(er)玻纖(xian)編(bian)(bian)織主要能(neng)(neng)起到防磨(mo)和耐(nai)熱作用；云母是種高(gao)(gao)性能(neng)(neng)緣制品(pin)，具有優良的(de)(de)(de)(de)耐(nai)高(gao)(gao)溫(wen)性能(neng)(neng)和耐(nai)燃燒性能(neng)(neng)；涂(tu)(tu)層能(neng)(neng)夠在(zai)起到防腐(fu)，耐(nai)磨(mo)，隔熱，緣；所(suo)(suo)以(yi)在(zai)選(xuan)(xuan)擇(ze)時玻纖(xian)編(bian)(bian)織、云母和涂(tu)(tu)層的(de)(de)(de)(de)質量也(ye)很重要。

此外，挑選線(xian)(xian)(xian)圈(quan)(quan)時(shi)，還要考(kao)慮(lv)其(qi)(qi)線(xian)(xian)(xian)徑，材質，耐(nai)溫(wen)(wen)耐(nai)壓性能(neng)(neng)等(deng)(deng)(deng)。這(zhe)些也都是(shi)由其(qi)(qi)使(shi)用(yong)(yong)(yong)條(tiao)件決定(ding)的(de)。在實際(ji)(ji)選配(pei)(pei)(pei)過(guo)程(cheng)中(zhong)(zhong)，先要根據加(jia)熱(re)需求確(que)定(ding)所(suo)需設備(bei)功(gong)率(lv)(lv)，然(ran)后(hou)就(jiu)(jiu)可(ke)以知道其(qi)(qi)輸出電(dian)(dian)(dian)(dian)流值(zhi)，進而(er)確(que)定(ding)線(xian)(xian)(xian)徑、材質，然(ran)后(hou)視現(xian)場(chang)的(de)溫(wen)(wen)度情(qing)(qing)況，散(san)熱(re)情(qing)(qing)況等(deng)(deng)(deng)考(kao)慮(lv)其(qi)(qi)耐(nai)溫(wen)(wen)性能(neng)(neng)。如果挑選線(xian)(xian)(xian)圈(quan)(quan)時(shi)沒(mei)有(you)考(kao)慮(lv)到(dao)(dao)這(zhe)些因素，就(jiu)(jiu)很(hen)(hen)容易出現(xian)設備(bei)故障，例如線(xian)(xian)(xian)圈(quan)(quan)被燒壞，加(jia)熱(re)效率(lv)(lv)低下，線(xian)(xian)(xian)圈(quan)(quan)不(bu)(bu)(bu)耐(nai)用(yong)(yong)(yong)等(deng)(deng)(deng)問(wen)題(ti)。輕則影響生(sheng)產，重則造成人身事故。二線(xian)(xian)(xian)圈(quan)(quan)繞(rao)(rao)制(zhi)(zhi)：表(biao)面看(kan)來，線(xian)(xian)(xian)圈(quan)(quan)繞(rao)(rao)制(zhi)(zhi)這(zhe)工作似乎是(shi)沒(mei)技術含量(liang)的(de)，不(bu)(bu)(bu)就(jiu)(jiu)是(shi)把(ba)線(xian)(xian)(xian)材繞(rao)(rao)下組成個(ge)線(xian)(xian)(xian)圈(quan)(quan)嘛(ma)，這(zhe)誰不(bu)(bu)(bu)會？但實際(ji)(ji)上(shang)并沒(mei)有(you)那么簡單，線(xian)(xian)(xian)圈(quan)(quan)的(de)繞(rao)(rao)制(zhi)(zhi)需要考(kao)慮(lv)到(dao)(dao)疊(die)加(jia)、干擾(rao)、散(san)熱(re)、距離(li)、感(gan)量(liang)匹配(pei)(pei)(pei)等(deng)(deng)(deng)因素。不(bu)(bu)(bu)同(tong)(tong)功(gong)率(lv)(lv)的(de)電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)器其(qi)(qi)所(suo)需要的(de)線(xian)(xian)(xian)圈(quan)(quan)電(dian)(dian)(dian)(dian)感(gan)量(liang)是(shi)不(bu)(bu)(bu)樣的(de)，只有(you)實際(ji)(ji)電(dian)(dian)(dian)(dian)感(gan)量(liang)和理論值(zhi)直，才能(neng)(neng)保證電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)器的(de)功(gong)率(lv)(lv)大(da)化(hua)。例如，臺30KW的(de)電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)器，其(qi)(qi)理論電(dian)(dian)(dian)(dian)感(gan)量(liang)是(shi)240μH，線(xian)(xian)(xian)圈(quan)(quan)繞(rao)(rao)制(zhi)(zhi)時(shi)，只有(you)實際(ji)(ji)感(gan)量(liang)為(wei)240μH，其(qi)(qi)功(gong)率(lv)(lv)才有(you)可(ke)能(neng)(neng)完全達到(dao)(dao)。如果實際(ji)(ji)感(gan)量(liang)是(shi)100μH、150μH、300μH、400μH，那其(qi)(qi)這(zhe)臺設備(bei)的(de)實際(ji)(ji)使(shi)用(yong)(yong)(yong)功(gong)率(lv)(lv)可(ke)能(neng)(neng)就(jiu)(jiu)只有(you)20KW，15KW，甚(shen)至根本啟動不(bu)(bu)(bu)了(le)。三適(shi)(shi)用(yong)(yong)(yong)見場(chang)：電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)器的(de)廣泛應用(yong)(yong)(yong)性決定(ding)了(le)其(qi)(qi)現(xian)場(chang)使(shi)用(yong)(yong)(yong)情(qing)(qing)況的(de)復雜。在電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)器眾多(duo)的(de)使(shi)用(yong)(yong)(yong)域中(zhong)(zhong)，食品、塑(su)料(liao)、化(hua)工、印刷、供暖(nuan)、垃圾處(chu)理，每個(ge)行業的(de)應用(yong)(yong)(yong)場(chang)景(jing)都不(bu)(bu)(bu)同(tong)(tong)，就(jiu)(jiu)是(shi)同(tong)(tong)個(ge)行業中(zhong)(zhong)，每個(ge)客戶的(de)使(shi)用(yong)(yong)(yong)現(xian)場(chang)也有(you)很(hen)(hen)大(da)的(de)差別。所(suo)以，電(dian)(dian)(dian)(dian)磁(ci)線(xian)(xian)(xian)圈(quan)(quan)不(bu)(bu)(bu)具有(you)普遍適(shi)(shi)用(yong)(yong)(yong)性，是(shi)種不(bu)(bu)(bu)同(tong)(tong)使(shi)用(yong)(yong)(yong)場(chang)景(jing)有(you)不(bu)(bu)(bu)同(tong)(tong)繞(rao)(rao)法的(de)非標配(pei)(pei)(pei)件。

電磁加熱器的全(quan)橋和(he)半橋的應用(yong)表現的同異：

、據各自的電路原理(li)的差(cha)別決定：相(xiang)同(tong)：均可達到使(shi)得(de)相(xiang)應料筒自身快速發(fa)熱產生高溫(wen)，用于加工塑料的功用。

二、功率段表現(xian)上不同：

1、全橋：對(dui)應檔(dang)位功(gong)率分配清晰、明確，反應迅速。

2、半橋(qiao)：對應檔位功(gong)率分配較(jiao)模糊，反應相對合(he)理。

三、發熱面表現上：

1、全橋(qiao)：因可負(fu)載負(fu)荷較(jiao)高，發熱(re)面(mian)較(jiao)大(da)、較(jiao)均勻、層次感能做(zuo)到(dao)循序遞減，火焰仿真(zhen)效果明(ming)顯。

2、半橋：因可負載負荷較低，發熱面較小、均勻性稍(shao)遜、層次感分(fen)明，火焰仿真效果稍(shao)遜。

電磁加熱(re)的優勢：不(bu)直接接觸產(chan)(chan)品(pin)，不(bu)會(hui)(hui)和金(jin)屬發生反應（如銅(tong)、鋁、鎳(nie)、不(bu)銹鋼(gang)等(deng)），也不(bu)會(hui)(hui)發出任何氣(qi)體，環保無毒，且設(she)計了過流(liu)(liu)、短(duan)路、缺相(xiang)、過壓(ya)、欠壓(ya)、過熱(re)、線圈開(kai)路、抗干擾、防雷擊(ji)等(deng)多(duo)項自(zi)動(dong)保護功能(neng)，不(bu)會(hui)(hui)發生短(duan)路。電磁加熱(re)裝(zhuang)置很好(hao)地結合了加熱(re)設(she)備(bei)應用環境和工作需要進行開(kai)發，對食品(pin)機械無需太多(duo)改動(dong)，便(bian)能(neng)輕松(song)達到節能(neng)30-50%的效果，并能(neng)節省預熱(re)時間，預熱(re)時間通(tong)(tong)常縮(suo)減到1/3左(zuo)右。具備(bei)節能(neng)降耗(hao)，精(jing)確控溫，可靠安(an)全等(deng)三大(da)特(te)點。電磁加熱(re)的原理是通(tong)(tong)過電子(zi)線路板組成部(bu)(bu)分產(chan)(chan)生交變磁場、當用含鐵(tie)質容器放(fang)置上面時，容器表面具即切割交變磁力線而(er)在(zai)容器底部(bu)(bu)金(jin)屬部(bu)(bu)分產(chan)(chan)生交變的電流(liu)(liu)（即渦流(liu)(liu)），渦流(liu)(liu)使容器底部(bu)(bu)的鐵(tie)原子(zi)高(gao)速無規(gui)則運動(dong)，原子(zi)互相(xiang)碰撞、摩擦而(er)產(chan)(chan)生熱(re)能(neng)。從而(er)起到加熱(re)物品(pin)的效果。
