電磁(ci)加熱器多溫區控制就是有(you)兩種：

第種：是臺電磁加熱(re)控制(zhi)器控制(zhi)多組線圈。

第(di)二種:是(shi)臺設(she)備(bei)使(shi)用多個(ge)電磁加(jia)(jia)熱控(kong)制(zhi)器分別控(kong)制(zhi)多個(ge)線圈。現在(zai)例如注(zhu)塑(su)機(ji)，拉絲機(ji)，吹膜機(ji)，擠出機(ji)等機(ji)械設(she)備(bei)，料管加(jia)(jia)熱部分都(dou)需要幾個(ge)不同溫(wen)(wen)度(du)才(cai)能滿足生產，這(zhe)時候就要使(shi)用到電磁加(jia)(jia)熱器多溫(wen)(wen)區來控(kong)制(zhi)。

第(di)三種：臺電磁加熱(re)(re)控(kong)制器(qi)控(kong)制多組線圈比較少用，因(yin)為如果主(zhu)機旦出現故障(zhang)，整個(ge)幾個(ge)溫度(du)都將無(wu)法加熱(re)(re)，影(ying)響(xiang)正規生(sheng)產，而(er)且維(wei)護起來也(ye)是比較麻煩的。

第四(si)種(zhong)：多(duo)個電(dian)磁加熱(re)控制器分別控制獨立線圈(quan)，這樣不但(dan)便于管理，而且加熱(re)非常(chang)均(jun)勻，維護起來也(ye)是(shi)十分方便的。

電磁加熱(re)器經常(chang)燒(shao)壞的幾個原因：

1、與工(gong)作環(huan)境有關：正常來(lai)說電(dian)(dian)磁(ci)加(jia)熱控(kong)(kong)制器(qi)工(gong)作環(huan)境般灰塵較多，灰塵多了之后，對電(dian)(dian)磁(ci)加(jia)熱控(kong)(kong)制主板就非常不利(li)。這就需(xu)要(yao)我(wo)們(men)要(yao)定期清理電(dian)(dian)磁(ci)加(jia)熱器(qi)上灰塵。其次(ci)就是室(shi)內通風(feng)(feng)要(yao)做好(hao)，避(bi)免風(feng)(feng)扇被卡住而(er)起不到(dao)主板散(san)熱效果從而(er)使得元器(qi)件過熱而(er)燒(shao)壞。

2、與工作(zuo)時(shi)長有關：般(ban)像家用的(de)電(dian)磁爐每天(tian)真正(zheng)工作(zuo)時(shi)間只有幾(ji)個小(xiao)時(shi)，而諸如(ru)塑料機之(zhi)類的(de)行業每天(tian)天(tian)的(de)工作(zuo)時(shi)間平均超(chao)過10小(xiao)時(shi)，許多廠家機器(qi)(qi)(qi)的(de)運作(zuo)時(shi)間甚至更長，因此，我們企業在選購時(shi)定(ding)要看準電(dian)磁加熱(re)控制器(qi)(qi)(qi)的(de)質量，購買高(gao)質量的(de)電(dian)磁加熱(re)控制器(qi)(qi)(qi)，或者合(he)理安排機器(qi)(qi)(qi)運作(zuo)時(shi)間。

3、與電(dian)(dian)磁(ci)加(jia)熱線圈(quan)有關(guan)：電(dian)(dian)磁(ci)加(jia)熱圈(quan)著水濕(shi)了或者破皮(pi)以及(ji)兩(liang)線之間短路等都是會造成(cheng)電(dian)(dian)磁(ci)加(jia)熱控制器(qi)燒壞(huai)。

4、出現間題不要擅自處(chu)理(li)：整流橋堆損壞導(dao)致跳閘，從而導(dao)致電磁加(jia)熱(re)控制器燒壞，因此，在遇到(dao)電磁加(jia)熱(re)設(she)備在工作時間突然(ran)跳閘不要擅自處(chu)理(li)，定(ding)要聯(lian)系我們技術人員來為(wei)您解(jie)決故障(zhang)，以(yi)避免過度損壞。

電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)熱(re)(re)器(qi)(qi)是(shi)(shi)種怎樣的(de)(de)(de)裝置：電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)熱(re)(re)器(qi)(qi)是(shi)(shi)種利用電(dian)(dian)(dian)磁(ci)(ci)(ci)感(gan)應(ying)原理將電(dian)(dian)(dian)能(neng)轉換為熱(re)(re)能(neng)的(de)(de)(de)裝置。在電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)熱(re)(re)器(qi)(qi)內(nei)部，由整流(liu)電(dian)(dian)(dian)路將50/60Hz的(de)(de)(de)交流(liu)電(dian)(dian)(dian)壓(ya)變(bian)(bian)成(cheng)直(zhi)流(liu)電(dian)(dian)(dian)壓(ya)，再(zai)(zai)經過控(kong)制電(dian)(dian)(dian)路將直(zhi)流(liu)電(dian)(dian)(dian)壓(ya)轉換成(cheng)頻(pin)率(lv)為15-20KHz的(de)(de)(de)高頻(pin)電(dian)(dian)(dian)壓(ya)，高速(su)(su)變(bian)(bian)化(hua)(hua)的(de)(de)(de)電(dian)(dian)(dian)流(liu)流(liu)過線圈會(hui)產(chan)(chan)生高速(su)(su)變(bian)(bian)化(hua)(hua)的(de)(de)(de)磁(ci)(ci)(ci)場，當磁(ci)(ci)(ci)場內(nei)的(de)(de)(de)磁(ci)(ci)(ci)力線通(tong)過金(jin)(jin)屬(shu)(shu)器(qi)(qi)皿(min)(min)(導磁(ci)(ci)(ci)又導電(dian)(dian)(dian)材料)底(di)部金(jin)(jin)屬(shu)(shu)體內(nei)產(chan)(chan)生無數的(de)(de)(de)小渦流(liu)，使器(qi)(qi)皿(min)(min)本身(shen)自行高速(su)(su)發熱(re)(re)，然后再(zai)(zai)加(jia)熱(re)(re)器(qi)(qi)皿(min)(min)內(nei)的(de)(de)(de)東西。而電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)熱(re)(re)本身(shen)對器(qi)(qi)皿(min)(min)和器(qi)(qi)皿(min)(min)內(nei)的(de)(de)(de)物品(pin)的(de)(de)(de)物理性質(zhi)和化(hua)(hua)學(xue)性質(zhi)不產(chan)(chan)生任何改變(bian)(bian)。

電阻(zu)線(xian)材(cai)加(jia)熱(re)過(guo)程中電能浪費的原因：傳統(tong)采暖行業(ye)普遍采用電阻(zu)導線(xian)和石(shi)英加(jia)熱(re)方(fang)式(shi)(shi)，這(zhe)種傳統(tong)加(jia)熱(re)方(fang)式(shi)(shi)熱(re)效率低。電阻(zu)絲(si)和石(shi)英主要通過(guo)電加(jia)熱(re)，然(ran)后熱(re)量(liang)轉移到(dao)(dao)料桶上。作為(wei)種加(jia)熱(re)材(cai)料，這(zhe)種加(jia)熱(re)效果的大熱(re)利(li)用率僅為(wei)50%左(zuo)右(you)，其余50%左(zuo)右(you)的熱(re)量(liang)被排放到(dao)(dao)空氣中。傳統(tong)電阻(zu)線(xian)材(cai)加(jia)熱(re)方(fang)式(shi)(shi)的電能損耗高(gao)達50%。

電磁加熱(re)器出現故障時的處理(li)方(fang)法(fa)：

、通過故(gu)障(zhang)(zhang)代(dai)碼自(zi)行(xing)(xing)解決：正規生產(chan)廠家的(de)電磁加(jia)熱設備如果(guo)出(chu)現(xian)故(gu)障(zhang)(zhang)都(dou)會(hui)有(you)相應(ying)的(de)故(gu)障(zhang)(zhang)代(dai)碼顯(xian)示，可(ke)(ke)以讓用(yong)戶目了然。出(chu)現(xian)問題該(gai)就(jiu)可(ke)(ke)以根據使用(yong)說明書上面的(de)故(gu)障(zhang)(zhang)代(dai)碼表找相應(ying)的(de)解決方法。當(dang)然，這需要(yao)用(yong)戶具備定(ding)的(de)專業常識，就(jiu)可(ke)(ke)以采用(yong)必(bi)要(yao)的(de)措施自(zi)行(xing)(xing)解決。

二(er)、通過售后(hou)(hou)服務(wu)解(jie)決：般正規電磁加熱器廠家(jia)(jia)是免(mian)費保修(xiu)年(nian)的(de)(de)，自行解(jie)決不了(le)的(de)(de)話(hua)，就應該積與生產(chan)廠家(jia)(jia)或經銷商聯系，通過廠家(jia)(jia)的(de)(de)售后(hou)(hou)服務(wu)來解(jie)決。好的(de)(de)生產(chan)廠家(jia)(jia)都提供優質的(de)(de)售后(hou)(hou)服務(wu)，能夠迅速(su)幫用戶解(jie)決問題。

三、過(guo)保(bao)修(xiu)(xiu)(xiu)期，售后(hou)服務解決：還有種就是(shi)電磁加(jia)熱(re)器的(de)保(bao)修(xiu)(xiu)(xiu)期已過(guo)后(hou)而(er)出現了(le)故障，這種的(de)話你到當時售賣的(de)電磁加(jia)熱(re)器廠(chang)家(jia)幫你維(wei)修(xiu)(xiu)(xiu)，般合理收取維(wei)修(xiu)(xiu)(xiu)費用(yong)(正規廠(chang)家(jia)不會亂(luan)收費的(de))，但是(shi)如果你不是(shi)到該廠(chang)家(jia)購買的(de)也是(shi)可(ke)以維(wei)修(xiu)(xiu)(xiu)的(de)。

電(dian)磁感應加熱器線圈發熱的問題：

1、如果將金(jin)(jin)屬物體置(zhi)于磁場中，或把(ba)它在磁場中切(qie)割磁力(li)線(xian)時(shi)，其內部會(hui)產生感應(ying)電(dian)流。這種感應(ying)電(dian)流會(hui)使金(jin)(jin)屬塊(kuai)會(hui)很快的發(fa)熱(re)(re)。電(dian)磁感應(ying)加熱(re)(re)器的線(xian)圈(quan)發(fa)熱(re)(re)要看溫(wen)度(du)(du)(du)達到多(duo)少(shao)度(du)(du)(du)，在般的情況下(xia)，電(dian)磁線(xian)圈(quan)的正常溫(wen)度(du)(du)(du)在70度(du)(du)(du)左右，80度(du)(du)(du)以(yi)下(xia)才是正常的，如果超過了90度(du)(du)(du)，肯定(ding)就(jiu)是有問題了。

2、電磁(ci)感應加熱器(qi)線圈(quan)本身的(de)(de)(de)(de)(de)問(wen)(wen)(wen)題(ti)：線圈(quan)的(de)(de)(de)(de)(de)問(wen)(wen)(wen)題(ti)就涉及(ji)的(de)(de)(de)(de)(de)質量和選配上(shang)了。（質量上(shang)的(de)(de)(de)(de)(de)問(wen)(wen)(wen)題(ti)就不(bu)講(jiang)解了），如果(guo)是(shi)使(shi)(shi)用(yong)(yong)高(gao)頻線，那線般問(wen)(wen)(wen)題(ti)不(bu)大。這種情況(kuang)其實還是(shi)主(zhu)板的(de)(de)(de)(de)(de)問(wen)(wen)(wen)題(ti)，我(wo)們(men)的(de)(de)(de)(de)(de)以(yi)前的(de)(de)(de)(de)(de)主(zhu)板也會有這個問(wen)(wen)(wen)題(ti)，因為主(zhu)板缺陷，而25平(ping)方的(de)(de)(de)(de)(de)線也比較粗(cu)了，集膚效應導致(zhi)線材發熱也是(shi)必(bi)然(ran)的(de)(de)(de)(de)(de)，以(yi)前我(wo)們(men)都是(shi)用(yong)(yong)多(duo)股漆(qi)包(bao)高(gao)頻線來解決密封電氣箱(xiang)內，每個器(qi)件的(de)(de)(de)(de)(de)發熱量的(de)(de)(de)(de)(de)，其實使(shi)(shi)用(yong)(yong)上(shang)沒什么區別，就是(shi)安裝(zhuang)變得繁瑣了些，不(bu)過現在公司的(de)(de)(de)(de)(de)電蔗感應加熱器(qi)已經改(gai)善，調整了機(ji)器(qi)的(de)(de)(de)(de)(de)Q值，并對整個機(ji)芯做(zuo)了隔熱、散熱處理(li)，斷不(bu)會出現單根25平(ping)方線高(gao)溫現象，所(suo)以(yi)如果(guo)大家買了機(ji)器(qi)發熱量過大，又不(bu)好退(tui)換的(de)(de)(de)(de)(de)話，可以(yi)考慮(lv)下用(yong)(yong)多(duo)股線來代替單的(de)(de)(de)(de)(de)25平(ping)方線，當然(ran)好還是(shi)找有實力的(de)(de)(de)(de)(de)公司購買，畢竟多(duo)少是(shi)因為設計問(wen)(wen)(wen)題(ti)而導致(zhi)的(de)(de)(de)(de)(de)發熱現象。

電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)的(de)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)情況是(shi)(shi)(shi)(shi)怎樣的(de)？工(gong)(gong)(gong)作(zuo)原理是(shi)(shi)(shi)(shi)把(ba)220V或(huo)者380V交流電(dian)(dian)(dian)(dian)，整(zheng)流后(hou)轉換成直(zhi)流電(dian)(dian)(dian)(dian)，再將直(zhi)流電(dian)(dian)(dian)(dian)進行濾波，利(li)用IGBT或(huo)者可(ke)(ke)控硅再將直(zhi)流變成交流，在感(gan)應(ying)線圈內產生高頻磁(ci)(ci)(ci)力線，是(shi)(shi)(shi)(shi)感(gan)應(ying)線圈內導體工(gong)(gong)(gong)件表面產生渦流依(yi)靠自生內阻發熱(re)(re)(re)(re)(re)。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)工(gong)(gong)(gong)作(zuo)中當(dang)(dang)溫(wen)度(du)(du)(du)沒達(da)(da)到設置的(de)溫(wen)度(du)(du)(du)時(shi)(shi)，電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)就(jiu)會(hui)(hui)直(zhi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)，當(dang)(dang)達(da)(da)到了(le)預設的(de)溫(wen)度(du)(du)(du)以后(hou)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)就(jiu)停(ting)止加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)了(le)，也就(jiu)不(bu)再耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)了(le)。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)每個小時(shi)(shi)的(de)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)多少與電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)時(shi)(shi)間長(chang)短有關(guan)。電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)剛工(gong)(gong)(gong)作(zuo)是(shi)(shi)(shi)(shi)滿功(gong)(gong)率(lv)，加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)溫(wen)度(du)(du)(du)了(le)，就(jiu)是(shi)(shi)(shi)(shi)工(gong)(gong)(gong)作(zuo)會(hui)(hui)，停(ting)會(hui)(hui)。總(zong)體上(shang)來說，電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)是(shi)(shi)(shi)(shi)很小的(de)，因(yin)為電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)不(bu)是(shi)(shi)(shi)(shi)直(zhi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)工(gong)(gong)(gong)作(zuo)的(de)，而是(shi)(shi)(shi)(shi)有間隙(xi)的(de)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)，先是(shi)(shi)(shi)(shi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)，然(ran)后(hou)達(da)(da)到溫(wen)度(du)(du)(du)后(hou)就(jiu)停(ting)止加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)，之(zhi)后(hou)就(jiu)開(kai)始保(bao)溫(wen)工(gong)(gong)(gong)作(zuo)，直(zhi)到溫(wen)度(du)(du)(du)沒達(da)(da)到預設的(de)溫(wen)度(du)(du)(du)后(hou)再加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)下，整(zheng)體上(shang)來講(jiang)，電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)并不(bu)是(shi)(shi)(shi)(shi)直(zhi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)的(de)，所以也是(shi)(shi)(shi)(shi)比較省(sheng)電(dian)(dian)(dian)(dian)的(de)個原因(yin)。同時(shi)(shi)因(yin)為料筒上(shang)還包有層保(bao)溫(wen)棉(mian)，能起到保(bao)溫(wen)和隔(ge)熱(re)(re)(re)(re)(re)的(de)效果，那么熱(re)(re)(re)(re)(re)量(liang)就(jiu)不(bu)會(hui)(hui)損失掉了(le)，那么能夠持續(xu)恒(heng)溫(wen)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)時(shi)(shi)間就(jiu)越長(chang)了(le)。耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)也就(jiu)越小了(le)。通過上(shang)述(shu)對電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)感(gan)應(ying)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)改造時(shi)(shi)所配功(gong)(gong)率(lv)的(de)介(jie)紹，我們可(ke)(ke)以了(le)解電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)時(shi)(shi)間越短那么耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)就(jiu)越小，反之(zhi)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)時(shi)(shi)間越長(chang)，耗(hao)(hao)(hao)電(dian)(dian)(dian)(dian)量(liang)就(jiu)越大。

電(dian)磁加熱(re)節電(dian)分析：電(dian)磁加熱(re)器在塑料機(ji)械上節能30%-70%是怎么(me)來的？

1、相比電(dian)阻加熱(re)(re)，電(dian)磁加熱(re)(re)器(qi)多了層保溫層，熱(re)(re)能利用率增(zeng)加。

2、相比電阻加熱(re)，電磁加熱(re)器直接作用于料管加熱(re)，減少了熱(re)傳遞熱(re)能損耗(hao)。

3、相比電(dian)阻(zu)加熱，電(dian)磁加熱器(qi)的加熱速(su)度(du)要快四(si)分之(zhi)以上，減(jian)少了加熱時間。

4、相(xiang)比電(dian)阻(zu)加熱，電(dian)磁(ci)加熱器(qi)的(de)加熱速度(du)快，生產效率(lv)就提高了(le)，讓電(dian)機處(chu)在飽和狀(zhuang)態，使(shi)其減(jian)少了(le)，高功(gong)率(lv)低需求造(zao)成的(de)電(dian)能損耗。
