下電磁加熱(re)器耗(hao)電與什么有關：

1、電磁(ci)(ci)加(jia)熱(re)(re)器在(zai)工(gong)作(zuo)中會(hui)直(zhi)(zhi)加(jia)熱(re)(re)到設(she)置的溫(wen)度(du)，當(dang)溫(wen)度(du)沒達到設(she)置的溫(wen)度(du)時，電磁(ci)(ci)加(jia)熱(re)(re)器就會(hui)直(zhi)(zhi)加(jia)熱(re)(re)，當(dang)達到了(le)預設(she)的溫(wen)度(du)以后(hou)電磁(ci)(ci)加(jia)熱(re)(re)器就停(ting)止加(jia)熱(re)(re)了(le)，也就不(bu)再耗電了(le)。

2、電(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)(qi)每(mei)個小(xiao)時(shi)的(de)(de)耗電(dian)(dian)量多(duo)少與電(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)(qi)加(jia)(jia)(jia)熱(re)的(de)(de)時(shi)間長(chang)短(duan)有關。電(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)(qi)剛工作是(shi)(shi)滿功率(lv)，加(jia)(jia)(jia)熱(re)溫(wen)度(du)(du)到(dao)溫(wen)度(du)(du)以后會停止(zhi)然(ran)后再加(jia)(jia)(jia)熱(re)。總(zong)體上來說，電(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)(qi)耗電(dian)(dian)量是(shi)(shi)很小(xiao)的(de)(de)，因為(wei)電(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)(qi)不(bu)是(shi)(shi)直加(jia)(jia)(jia)熱(re)工作的(de)(de)，而是(shi)(shi)有間隙的(de)(de)加(jia)(jia)(jia)熱(re)的(de)(de)，達到(dao)溫(wen)度(du)(du)后就(jiu)停止(zhi)加(jia)(jia)(jia)熱(re)，之(zhi)后就(jiu)開始保(bao)溫(wen)工作，直到(dao)溫(wen)度(du)(du)沒達到(dao)預設的(de)(de)溫(wen)度(du)(du)后再加(jia)(jia)(jia)熱(re)下(xia)，整體上來講，電(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)(qi)并不(bu)是(shi)(shi)直加(jia)(jia)(jia)熱(re)耗電(dian)(dian)的(de)(de)，這也是(shi)(shi)它比較省電(dian)(dian)的(de)(de)個原因。

3、料(liao)筒上還包有層(ceng)保溫(wen)棉也能起到(dao)保溫(wen)和(he)隔熱的效果，那么(me)熱量(liang)就(jiu)(jiu)不會(hui)損失掉了(le)，那么(me)能夠(gou)持續恒溫(wen)加熱的時間(jian)就(jiu)(jiu)越長了(le)。耗電量(liang)也就(jiu)(jiu)越小(xiao)了(le)。

電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱板的(de)(de)除塵(chen)(chen)方法有哪些：電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱板很(hen)(hen)(hen)好(hao)的(de)(de)解決了傳統加(jia)(jia)(jia)(jia)熱器的(de)(de)各種弊端，尤其是資源浪費方面，電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱板的(de)(de)能量轉化(hua)率(lv)非(fei)(fei)常的(de)(de)高(gao)，使(shi)用(yong)電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱板雖(sui)然是非(fei)(fei)常的(de)(de)方便，但是對(dui)其做好(hao)除塵(chen)(chen)的(de)(de)工作(zuo)也是非(fei)(fei)常有必(bi)要的(de)(de)，如果積(ji)累大量的(de)(de)灰塵(chen)(chen)，對(dui)于加(jia)(jia)(jia)(jia)熱的(de)(de)性能會(hui)造成(cheng)很(hen)(hen)(hen)大的(de)(de)影響。電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱器的(de)(de)使(shi)用(yong)給工廠帶來了很(hen)(hen)(hen)多(duo)便利，電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱改造后工人工作(zuo)環(huan)境得到很(hen)(hen)(hen)大提高(gao)。為了更好(hao)的(de)(de)使(shi)用(yong)該設(she)備，請(qing)設(she)備維護人員及時做好(hao)電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱除塵(chen)(chen)的(de)(de)。電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱器提醒(xing)您要經(jing)常清掃加(jia)(jia)(jia)(jia)熱器里(li)的(de)(de)灰塵(chen)(chen)，還要保(bao)證電(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)(jia)熱器所處(chu)位(wei)置通風。

電磁感應(ying)加熱器控制溫度場(chang)的分布(bu)的原(yuan)理及方法如下：

1、原理：導體處于交(jiao)變(bian)電流(liu)中時，交(jiao)變(bian)電流(liu)使導體周圍產(chan)生交(jiao)變(bian)磁場，從而引(yin)起集(ji)膚效應使導體在(zai)短時間(jian)內迅速被(bei)加(jia)熱，交(jiao)變(bian)電流(liu)的頻率越高，集(ji)膚效應越嚴重。

2、電(dian)(dian)(dian)(dian)流(liu)透入深度(du)對感應加(jia)熱的(de)(de)(de)(de)影響：把金屬(shu)圓柱體放(fang)在通有交流(liu)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)線圈中(zhong)，盡管金屬(shu)圓柱不與線圈接觸(chu)，線圈本身(shen)的(de)(de)(de)(de)溫度(du)也很低(di)，但是圓柱表面(mian)卻會被加(jia)熱到發紅，甚至熔化，這是由(you)于電(dian)(dian)(dian)(dian)磁感應作用，在金屬(shu)柱中(zhong)感生(sheng)與線圈電(dian)(dian)(dian)(dian)流(liu)方向相反的(de)(de)(de)(de)渦(wo)流(liu),在渦(wo)流(liu)的(de)(de)(de)(de)焦耳熱作用下，金屬(shu)自身(shen)發熱升溫所(suo)引(yin)起的(de)(de)(de)(de)。金屬(shu)圓柱中(zhong)的(de)(de)(de)(de)感生(sheng)電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)分布在表面(mian)強(qiang)，在徑(jing)向從外到里(li)按指數(shu)函數(shu)方式減小(xiao)。這種電(dian)(dian)(dian)(dian)流(liu)不均(jun)勻(yun)分布的(de)(de)(de)(de)現象(xiang)，隨(sui)電(dian)(dian)(dian)(dian)流(liu)頻(pin)率(lv)升高(gao)而(er)趨顯著。

電磁加熱器(qi)應用范圍：

1、塑(su)料橡膠(jiao)行(xing)業，如：塑(su)料用(yong)吹(chui)膜(mo)機(ji)(ji)、拉絲機(ji)(ji)、注(zhu)塑(su)機(ji)(ji)，造(zao)粒機(ji)(ji)，橡膠(jiao)用(yong)擠(ji)出(chu)機(ji)(ji)、硫化機(ji)(ji)、電纜(lan)生產擠(ji)出(chu)機(ji)(ji)等。

2、醫(yi)藥化(hua)工行業(ye)，如：醫(yi)藥專用(yong)輸液(ye)袋、塑料器材生產線，化(hua)工行業(ye)液(ye)體(ti)加(jia)熱輸送管道(dao)等(deng)等(deng)。

3、能源、食(shi)品(pin)(pin)行業，如：原油輸(shu)送管道的加熱；食(shi)品(pin)(pin)機械，如：超貨機等需要電加熱的設備(bei)。

4、大功率商(shang)用電磁(ci)灶(zao)機芯。

5、建(jian)材行業，如(ru)：燃氣管(guan)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)、塑料(liao)管(guan)材生(sheng)(sheng)產(chan)(chan)線(xian)(xian)、PE塑料(liao)硬質(zhi)平網(wang)(wang)、土工網(wang)(wang)機(ji)組、自動(dong)中(zhong)空(kong)成型(xing)機(ji)、PE蜂窩板生(sheng)(sheng)產(chan)(chan)線(xian)(xian)、單(dan)雙壁波(bo)紋管(guan)擠(ji)出(chu)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)、復(fu)合氣墊膜機(ji)組、PVC硬管(guan)、芯層發(fa)泡(pao)管(guan)生(sheng)(sheng)產(chan)(chan)線(xian)(xian)、PP擠(ji)出(chu)透明片材生(sheng)(sheng)產(chan)(chan)線(xian)(xian)、擠(ji)出(chu)聚苯乙烯發(fa)泡(pao)管(guan)材、PE纏繞膜機(ji)組。

6、印刷設備里(li)的干燥加(jia)熱(re)。

7、其它類(lei)似行業(ye)加(jia)熱。

電磁加(jia)熱(re)器(qi)的(de)使用壽(shou)命(ming)卻和以下幾個點有(you)著密不可分的(de)關系：

1、產品(pin)定要保證(zheng)產品(pin)正確的(de)(de)(de)安裝(zhuang)(zhuang)。每款(kuan)電(dian)(dian)磁加熱器及電(dian)(dian)磁加熱圈(quan)所(suo)要求的(de)(de)(de)保溫棉的(de)(de)(de)厚道，繞(rao)線的(de)(de)(de)粗細長度(du)，電(dian)(dian)感值，輸(shu)入電(dian)(dian)流值都是不同的(de)(de)(de)，要嚴格按(an)照廠家出(chu)廠時安裝(zhuang)(zhuang)說明書(shu)為標準(zhun)。

2、使用壽命與環(huan)(huan)境分不開關系，諸如(ru)粉塵，灰塵，潮濕度(du)等等因素。如(ru)果空氣中的(de)(de)(de)粉塵灰塵超過定(ding)比例，就會(hui)對(dui)電磁加熱(re)控制主板(ban)造成(cheng)較大的(de)(de)(de)影響。使用者需要定(ding)期專門企業清(qing)理維(wei)護電磁加熱(re)器，室內(nei)的(de)(de)(de)通風要好，良好的(de)(de)(de)環(huan)(huan)境會(hui)大幅提(ti)升(sheng)電磁加熱(re)器的(de)(de)(de)壽命。

3、不(bu)得不(bu)說的(de)是，使用壽命(ming)與產(chan)品(pin)(pin)的(de)質(zhi)量(liang)也分(fen)不(bu)開。機器所采用的(de)原器件(jian)，電路板設計合理與否會(hui)導致(zhi)終的(de)產(chan)品(pin)(pin)質(zhi)量(liang)會(hui)有很大出(chu)入，如何選(xuan)擇專業的(de)電磁加(jia)熱器品(pin)(pin)是重(zhong)中之重(zhong)。

4、使(shi)用(yong)壽(shou)(shou)命與對產品的(de)愛護程(cheng)度(du)關(guan)系也密不可分。個(ge)被好(hao)好(hao)愛護使(shi)用(yong)的(de)機器(qi)(qi)對要(yao)比個(ge)從不愛護保養的(de)機器(qi)(qi)壽(shou)(shou)命要(yao)長。

普通加(jia)熱圈(quan)加(jia)熱方式:接觸(chu)式熱傳(chuan)遞加(jia)熱：

1、耗電(dian)的 30-70% 轉化為工作熱能。

2、加熱通(tong)過(guo)接觸方式傳遞(di)熱能。

3、加熱及冷卻(que)都有慣性現象(xiang)產生，及升溫降溫都緩(huan)慢(man)。

4、加(jia)熱有死角(jiao)，不能完全包(bao)裹在(zai)料筒外層。

5、加熱圈損耗(hao)大，壽命短(duan)。

哪(na)些因素會導(dao)致電磁加熱器(qi)發生故障(zhang)？

：電磁(ci)加熱器電路(lu)設計不科學(xue)。目前，在(zai)(zai)大(da)功率(lv)電磁(ci)加熱電路(lu)系統中(zhong)，大(da)部(bu)分廠(chang)家采(cai)用過去(qu)的(de)(de)(de)傳統模(mo)擬3525或(huo)494電路(lu)，產生(sheng)兩路(lu)或(huo)四路(lu)PWM，采(cai)用調頻方法驅(qu)動(dong)IGBT，改變諧振回電流(liu)大(da)小來達到調節功率(lv)大(da)小的(de)(de)(de)目的(de)(de)(de)，再(zai)采(cai)用4046進行鎖(suo)相(xiang)控制(zhi)，在(zai)(zai)工業上加熱應用已經很普遍，技(ji)術也(ye)比較(jiao)成熟。但是，它的(de)(de)(de)硬(ying)件電路(lu)復雜，所(suo)以大(da)多體(ti)積龐(pang)大(da)，也(ye)不便于生(sheng)產和(he)調試，特(te)別是容易由于所(suo)選(xuan)用的(de)(de)(de)器件特(te)性(xing)差(cha)異，致使電源致性(xing)差(cha)，工作中(zhong)生(sheng)產的(de)(de)(de)高強的(de)(de)(de)電磁(ci)干擾(rao)時，鎖(suo)相(xiang)或(huo)保護部(bu)分容易失靈，容易造成故障。

二：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力器件(jian)布局不(bu)合理(li)。在(zai)大(da)功(gong)(gong)率(lv)(lv)工業電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)熱主(zhu)結(jie)構電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中，常(chang)為(wei)半(ban)橋(qiao)(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)和全(quan)(quan)橋(qiao)(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，通常(chang)2-25KW功(gong)(gong)率(lv)(lv)別采用(yong)半(ban)橋(qiao)(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，全(quan)(quan)橋(qiao)(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)可以實現20KW以上功(gong)(gong)率(lv)(lv)。般(ban)地(di)，功(gong)(gong)率(lv)(lv)大(da)于(yu)(yu)25KW后，線(xian)圈的高頻(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流比較大(da)，發熱比較多，當(dang)主(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力功(gong)(gong)率(lv)(lv)器件(jian)布局不(bu)合理(li)時(shi)(shi)，可能(neng)會產生高強干擾，有可能(neng)使慮波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容、揩振電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容或IGBT模(mo)塊(kuai)擊(ji)穿(chuan)。為(wei)了用(yong)戶(hu)的安裝安全(quan)(quan)考慮，般(ban)把半(ban)橋(qiao)(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)大(da)功(gong)(gong)率(lv)(lv)定(ding)為(wei)15KW，降低IGBT模(mo)塊(kuai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流應力，當(dang)功(gong)(gong)率(lv)(lv)大(da)于(yu)(yu)20KW時(shi)(shi)，建議用(yong)戶(hu)選擇全(quan)(quan)橋(qiao)(qiao)主(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)結(jie)構。當(dang)然，在(zai)特定(ding)的應用(yong)場合，需要(yao)加(jia)(jia)熱面積比小，功(gong)(gong)率(lv)(lv)密度比較大(da)時(shi)(shi)，我(wo)們(men)合理(li)科學(xue)地(di)可以幫助用(yong)戶(hu)把半(ban)橋(qiao)(qiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)安全(quan)(quan)做到(dao)30KW。
