電(dian)磁(ci)加(jia)熱器安全使用(yong)的幾個(ge)知識：

1、在使用時，不(bu)可(ke)將易燃易爆物品(pin)放在電磁加熱(re)器(qi)鄰近，需要有(you)定的安全間隔(ge)。

2、電磁加熱(re)器要放在不(bu)(bu)導熱(re)的(de)不(bu)(bu)燃材料基(ji)座上(shang)。

3、電磁加熱器導(dao)線的安全截流量要(yao)滿足電磁加熱器的容(rong)量需(xu)求。

4、工業用電磁(ci)加熱(re)器(qi)在任(ren)何情況下都(dou)要設立設備獨自存在的(de)電路。

5、導線(xian)必需設(she)(she)置(zhi)設(she)(she)備插頭，不(bu)可(ke)將電(dian)磁(ci)加(jia)熱器線(xian)頭直接插入插座；電(dian)磁(ci)加(jia)熱器導線(xian)老化破(po)損應當及時替換，電(dian)路中沒有設(she)(she)備熔斷(duan)器的電(dian)磁(ci)加(jia)熱器不(bu)得開啟(qi)使用。

6、電(dian)(dian)磁加熱(re)器(qi)(qi)(qi)在運用時若遇停電(dian)(dian)，應及時將電(dian)(dian)磁加熱(re)器(qi)(qi)(qi)插頭拔(ba)出，不(bu)要忘記。對于屢(lv)次修補的(de)(de)電(dian)(dian)阻(zu)絲，應替換(huan)新的(de)(de)電(dian)(dian)阻(zu)絲，不(bu)再運用老(lao)舊電(dian)(dian)阻(zu)絲。易(yi)燃易(yi)爆物品禁(jin)止用電(dian)(dian)磁加熱(re)器(qi)(qi)(qi)烘干；電(dian)(dian)烘箱應有控制溫度(du)的(de)(de)設備(bei)，既要避免溫度(du)過(guo)(guo)高(gao)，又要避免電(dian)(dian)磁加熱(re)器(qi)(qi)(qi)烘烤時間過(guo)(guo)長。

電(dian)磁(ci)加(jia)熱(re)(re)簡介：電(dian)磁(ci)加(jia)熱(re)(re)也稱電(dian)磁(ci)感應加(jia)熱(re)(re)，即(ji)電(dian)磁(ci)加(jia)熱(re)(re)(外文:Electromagnetic heating縮寫(xie)：EH)技(ji)術(shu)，電(dian)磁(ci)加(jia)熱(re)(re)的原理是(shi)(shi)通過(guo)電(dian)子線路板組成部(bu)分產(chan)(chan)生交變(bian)磁(ci)場(chang)、當用(yong)含(han)鐵質容器(qi)(qi)(qi)放置上面(mian)時(shi)，容器(qi)(qi)(qi)表(biao)面(mian)即(ji)切割交變(bian)磁(ci)力線而(er)在容器(qi)(qi)(qi)底部(bu)金屬部(bu)分產(chan)(chan)生交變(bian)的電(dian)流（即(ji)渦流），渦流使容器(qi)(qi)(qi)底部(bu)的載流子高速無規(gui)則運動，載流子與(yu)原子互相碰撞、摩擦而(er)產(chan)(chan)生熱(re)(re)能。從而(er)起(qi)到加(jia)熱(re)(re)物品(pin)的效果。因(yin)為是(shi)(shi)鐵制容器(qi)(qi)(qi)自(zi)身發熱(re)(re)，所以熱(re)(re)轉化率特(te)別高，高可(ke)達(da)到95%是(shi)(shi)種直接加(jia)熱(re)(re)的方(fang)式。電(dian)磁(ci)爐，電(dian)磁(ci)灶 電(dian)磁(ci)加(jia)熱(re)(re)電(dian)飯鍋(guo)都是(shi)(shi)采用(yong)的電(dian)磁(ci)加(jia)熱(re)(re)技(ji)術(shu)。

電磁加熱器IGBT溫(wen)度傳感器異常解決方(fang)法：

1、出(chu)現傳感器異常(chang)(chang)后請先將傳感器引線主板上拔下(xia)，再用萬用表測量其(qi)阻(zu)值，常(chang)(chang)溫25℃時阻(zu)值應(ying)約為10K，否則(ze)傳感器已損壞。

2、如傳(chuan)(chuan)感器正常，再檢(jian)測傳(chuan)(chuan)感器引(yin)線是(shi)否與(yu)CN3連接正常。C36、R16是(shi)否開(kai)、短路。

3、檢測U5第(di)16腳是否(fou)連(lian)接正常。

電磁加熱器(qi)(qi)(qi)裝置后溫(wen)(wen)度不(bu)達(da)標處理方(fang)法，當為注塑機(ji)類似(si)小功率(lv)時(shi)，安裝電磁加熱器(qi)(qi)(qi)后有些機(ji)器(qi)(qi)(qi)溫(wen)(wen)度總是(shi)差點點。當把功率(lv)換原(yuan)來(lai)還(huan)大(da)(da)后還(huan)是(shi)這樣。有時(shi)總讓(rang)人摸(mo)不(bu)著頭腦，大(da)(da)多數不(bu)是(shi)功率(lv)安裝小的(de)原(yuan)因(yin)的(de)，這是(shi)由于(yu)原(yuan)來(lai)機(ji)器(qi)(qi)(qi)中的(de)溫(wen)(wen)控制器(qi)(qi)(qi)輸出(chu)的(de)PID運算方(fang)法引起的(de)，啟動信(xin)號很短，電磁加熱器(qi)(qi)(qi)都還(huan)沒(mei)有來(lai)得及工作，又(you)斷了。所(suo)以(yi)電磁加熱器(qi)(qi)(qi)大(da)(da)多數時(shi)間處理停(ting)止狀態(tai)，沒(mei)有加熱。這時(shi)我們可以(yi)調節機(ji)器(qi)(qi)(qi)中的(de)斷開延時(shi)工作時(shi)間，來(lai)達(da)到溫(wen)(wen)度要(yao)求。注意(yi)，不(bu)能(neng)調節太大(da)(da)。否則可能(neng)會超溫(wen)(wen)。

電磁(ci)感應加熱器應用超溫(wen)怎么辦：

1、熱電(dian)偶(ou)接頭兩端可(ke)以并個102P瓷片電(dian)容以消除(chu)高頻干擾。

2、檢(jian)查下(xia)炮筒(tong)接地是否良好？嘗試(shi)炮筒(tong)強制(zhi)接地處(chu)理(li)。

3、可以把線圈遠離下熱電偶，減小干(gan)擾。

4、嘗試下用高溫布把(ba)熱(re)電(dian)偶(ou)包住(zhu)，讓它不要(yao)與(yu)炮筒(tong)接觸(chu)。

5、嘗試(shi)換(huan)條新的熱(re)電(dian)偶。

6、嘗試下注塑機控制電腦中心(xin)加個Pai型(xing)慮波器，減(jian)小電源(yuan)干擾。

電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱器是種怎樣的(de)(de)(de)裝(zhuang)置(zhi)：電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱器是種利用電(dian)(dian)(dian)(dian)磁(ci)感應(ying)原(yuan)理將(jiang)電(dian)(dian)(dian)(dian)能轉換為(wei)熱能的(de)(de)(de)裝(zhuang)置(zhi)。在電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱器內(nei)部，由整(zheng)流電(dian)(dian)(dian)(dian)路將(jiang)50/60Hz的(de)(de)(de)交流電(dian)(dian)(dian)(dian)壓變(bian)成(cheng)直(zhi)流電(dian)(dian)(dian)(dian)壓，再經過(guo)(guo)控制電(dian)(dian)(dian)(dian)路將(jiang)直(zhi)流電(dian)(dian)(dian)(dian)壓轉換成(cheng)頻(pin)率為(wei)15-20KHz的(de)(de)(de)高頻(pin)電(dian)(dian)(dian)(dian)壓，高速(su)(su)變(bian)化(hua)的(de)(de)(de)電(dian)(dian)(dian)(dian)流流過(guo)(guo)線圈(quan)會產生高速(su)(su)變(bian)化(hua)的(de)(de)(de)磁(ci)場，當磁(ci)場內(nei)的(de)(de)(de)磁(ci)力(li)線通過(guo)(guo)金屬器皿(導磁(ci)又導電(dian)(dian)(dian)(dian)材料)底部金屬體內(nei)產生無數(shu)的(de)(de)(de)小渦流，使器皿本(ben)身(shen)自行高速(su)(su)發熱，然后再加(jia)(jia)熱器皿內(nei)的(de)(de)(de)東西。而電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱本(ben)身(shen)對(dui)器皿和器皿內(nei)的(de)(de)(de)物(wu)品的(de)(de)(de)物(wu)理性(xing)質和化(hua)學性(xing)質不產生任何改(gai)變(bian)。
