電磁加熱(re)板(ban)為什么容易(yi)出(chu)問題？平(ping)時(shi)沒有注意機器(qi)內部清(qing)潔，灰塵過多導致機器(qi)短路。板(ban)子設計缺陷。模塊問題。

電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)(re)能(neng)(neng)省電(dian)(dian)的(de)原因及(ji)效果：電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)(re)器的(de)原理(li)是電(dian)(dian)磁(ci)(ci)感(gan)應(ying)加(jia)熱(re)(re)(re)的(de)原理(li)，它采(cai)用(yong)內部加(jia)熱(re)(re)(re)的(de)方法，即讓材(cai)料自身發熱(re)(re)(re)，而不(bu)是傳遞(di)熱(re)(re)(re)量(liang)，它是通過(guo)電(dian)(dian)、磁(ci)(ci)和(he)熱(re)(re)(re)之間的(de)能(neng)(neng)量(liang)轉換來達到加(jia)熱(re)(re)(re)材(cai)料的(de)目的(de)。此(ci)外(wai)，還有包裝20Mm厚的(de)保溫(wen)棉外(wai)容器的(de)材(cai)料。可以說，電(dian)(dian)磁(ci)(ci)感(gan)應(ying)加(jia)熱(re)(re)(re)過(guo)程(cheng)中存在的(de)熱(re)(re)(re)量(liang)損失很低，熱(re)(re)(re)能(neng)(neng)利(li)用(yong)率(lv)高達98%。相反，電(dian)(dian)磁(ci)(ci)感(gan)應(ying)加(jia)熱(re)(re)(re)的(de)節電(dian)(dian)效果是相當可觀的(de)，用(yong)電(dian)(dian)磁(ci)(ci)輻(fu)射熱(re)(re)(re)利(li)用(yong)率(lv)的(de)高值(zhi)和(he)低值(zhi)減去(qu)電(dian)(dian)阻(zu)加(jia)熱(re)(re)(re)的(de)小(xiao)值(zhi)和(he)大值(zhi)，就可以從(cong)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)(re)中獲得種節約(yue)電(dian)(dian)量(liang)。

在使用電磁加熱器時要注意(yi)什么？

1、使(shi)用程要輕易拆(chai)除(chu)電磁加(jia)熱控制(zhi)板接導線接措施防止(zhi)觸電道保護措施。

2、要定期清(qing)理散(san)熱(re)器保證(zheng)電磷感(gan)應(ying)加(jia)熱(re)器通風。

3、使用電(dian)(dian)磁加熱器應先按說明書繞(rao)線圈并檢查誤再接通電(dian)(dian)源(yuan)。

4、保(bao)養(yang)清(qing)洗電磁(ci)加熱器(qi)前(qian)切斷電磁(ci)加熱器(qi)電源清(qing)潔電磁(ci)加熱器(qi)外(wai)殼應用干凈抹(mo)布進行(xing)擦(ca)拭嚴(yan)禁用噴射(she)水流沖洗外(wai)殼及電器(qi)箱(xiang)部(bu)。

5、要電磁加熱器安裝潮濕環境防止水蒸汽進入電箱(xiang)易緣介質表面凝結降(jiang)低其緣性能造(zao)漏電事(shi)故。

6、要經檢查電磁加熱(re)器進(jin)風(feng)(feng)口及散熱(re)風(feng)(feng)扇(shan)防止(zhi)進(jin)風(feng)(feng)口處堵(du)塞或散熱(re)風(feng)(feng)扇(shan)卡死避免(mian)熱(re)停機保護(hu)。

電磁加熱器(qi)的電流小(xiao)于(yu)5A時，控制(zhi)器(qi)會自動檢測(ce)，如果連(lian)續超過(guo)三(san)次(ci)檢測(ce)均小(xiao)于(yu)5A時顯示窗1會顯示“E1”并閃爍，“電流小(xiao)”指示燈會閃爍提示，蜂鳴音每5秒短響(xiang)次(ci)。解(jie)決方法：

1、確(que)認(ren)線圈是否已正確(que)連接(jie)。

2、檢測與低頻互感(gan)器相(xiang)連的(de)相(xiang)線是否正(zheng)常。

3、檢測低頻互感器是否開、短路。

4、檢測CN7連接是否正常。

5、檢測C39、DB1、R30、C41、R19、C40、C42、是否短(duan)路。

6、檢測(ce)DB1、R20、R18是否開路。

7、檢測(ce)U5第18腳是否接觸良好。

如何選擇(ze)合適功率的電(dian)磁感應加熱器？

1、被加熱的工(gong)件(jian)形(xing)狀(zhuang)和尺寸：工(gong)件(jian)大、棒(bang)料、實材，應(ying)選(xuan)用相對(dui)功率(lv)(lv)(lv)大，頻率(lv)(lv)(lv)低的感應(ying)加熱設備；工(gong)件(jian)小(xiao)、管(guan)材、板材、齒輪等，則(ze)選(xuan)用相對(dui)功率(lv)(lv)(lv)小(xiao)，頻率(lv)(lv)(lv)高的電磁感應(ying)加熱器。

2、需要加(jia)熱的(de)深度和面(mian)積：加(jia)熱深度深，面(mian)積大，整體加(jia)熱，應(ying)選(xuan)用(yong)功率(lv)大，頻率(lv)低的(de)感(gan)應(ying)加(jia)熱設(she)備(bei)；加(jia)熱深度淺，面(mian)積小(xiao)，局部加(jia)熱，選(xuan)用(yong)相(xiang)對功率(lv)小(xiao)，頻率(lv)高的(de)電(dian)磁感(gan)應(ying)加(jia)熱設(she)備(bei)。

3、所需的加(jia)熱速度：需要的加(jia)熱速度快，應(ying)選用功率相(xiang)對(dui)(dui)較(jiao)大，頻率相(xiang)對(dui)(dui)較(jiao)高的感應(ying)加(jia)熱設備。

4、工藝要求(qiu)：般(ban)來說，淬火、焊接(jie)等工藝，相對(dui)可以功率選(xuan)(xuan)小些(xie)，頻率選(xuan)(xuan)高(gao)些(xie)；退火、回火等工藝，相對(dui)功率選(xuan)(xuan)大些(xie)，頻率選(xuan)(xuan)低些(xie)；紅(hong)沖、熱殿、熔煉等，需要透(tou)熱效果好的工藝，則電磁加(jia)熱器功率應選(xuan)(xuan)得(de)更大，頻率選(xuan)(xuan)得(de)更低。
