電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器可以多溫(wen)(wen)(wen)(wen)區(qu)(qu)控制(zhi)嗎？橡(xiang)膠(jiao)(jiao)機(ji)(ji)多溫(wen)(wen)(wen)(wen)區(qu)(qu)加(jia)(jia)(jia)熱(re)(re)(re)(re)早些(xie)年常用(yong)(yong)的莫過于(yu)電(dian)(dian)阻加(jia)(jia)(jia)熱(re)(re)(re)(re)，這(zhe)(zhe)種加(jia)(jia)(jia)熱(re)(re)(re)(re)方式熱(re)(re)(re)(re)效率(lv)不高，耗(hao)電(dian)(dian)量比較(jiao)大。目前理想的橡(xiang)膠(jiao)(jiao)機(ji)(ji)多溫(wen)(wen)(wen)(wen)區(qu)(qu)加(jia)(jia)(jia)熱(re)(re)(re)(re)建議采用(yong)(yong)電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器加(jia)(jia)(jia)熱(re)(re)(re)(re)設備，通(tong)過電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)圈產生渦(wo)流使管(guan)(guan)(guan)道(dao)(dao)自身發熱(re)(re)(re)(re)。管(guan)(guan)(guan)道(dao)(dao)加(jia)(jia)(jia)包層2.5公分的保溫(wen)(wen)(wen)(wen)棉，這(zhe)(zhe)樣熱(re)(re)(re)(re)量不容易外散到空氣(qi)。電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)圈的外部(bu)溫(wen)(wen)(wen)(wen)度(du)只有幾十度(du)，工(gong)作室溫(wen)(wen)(wen)(wen)也會(hui)由此而(er)減低。晶星電(dian)(dian)子科技有限公司據用(yong)(yong)戶親自測試，橡(xiang)膠(jiao)(jiao)機(ji)(ji)多溫(wen)(wen)(wen)(wen)區(qu)(qu)改用(yong)(yong)電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器相比電(dian)(dian)熱(re)(re)(re)(re)圈至少(shao)省(sheng)電(dian)(dian)在30%以上，非常實用(yong)(yong)。橡(xiang)膠(jiao)(jiao)機(ji)(ji)多溫(wen)(wen)(wen)(wen)區(qu)(qu)加(jia)(jia)(jia)熱(re)(re)(re)(re)般為(wei)多條(tiao)加(jia)(jia)(jia)熱(re)(re)(re)(re)管(guan)(guan)(guan)道(dao)(dao)，條(tiao)管(guan)(guan)(guan)道(dao)(dao)使用(yong)(yong)2組(zu)或(huo)者多組(zu)電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器。實際要根據橡(xiang)膠(jiao)(jiao)機(ji)(ji)加(jia)(jia)(jia)熱(re)(re)(re)(re)管(guan)(guan)(guan)道(dao)(dao)尺寸而(er)定。電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)板使用(yong)(yong)功率(lv)般為(wei)15kw-20kw電(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器。

磁加熱(re)器安(an)裝的要求有(you)什么?

1、電(dian)磁加(jia)熱(re)器要安裝在不進水或水霧、不潮濕、干凈的工作環(huan)境。

2、電磁加熱(re)器如(ru)果安裝在(zai)電柜中，定要做好通風，保證設(she)備散熱(re)良好。

3、電磁加熱(re)器的風(feng)扇和進風(feng)口很容易堆積灰塵(chen)(chen)，平(ping)常需(xu)要(yao)檢(jian)查和清理灰塵(chen)(chen)，以防風(feng)扇燒壞或者進風(feng)口處堵塞，防止加熱(re)器過熱(re)導致機(ji)器故障(zhang)。

4、對(dui)于(yu)(yu)功率大(da)的電(dian)磁加熱器，380V接線(xian)應按4～6A/mm2安(an)(an)裝，零(ling)線(xian)接大(da)于(yu)(yu)1mm2就(jiu)可以。對(dui)于(yu)(yu)220V電(dian)磁加熱器，火線(xian)和零(ling)線(xian)同時應按4～6A/mm2安(an)(an)裝，以保證使用安(an)(an)全(quan)。

普及(ji)下電(dian)磁(ci)(ci)加熱(re)器的(de)應用原理，電(dian)磁(ci)(ci)加熱(re)是將380V50Hz交流電(dian)變成530VDC-560VDC50HZ直流電(dian)，再經過變頻(pin)控制(zhi)技(ji)術逆變成5KHZ-30Hz的(de)高頻(pin)交流電(dian)流，通過電(dian)磁(ci)(ci)加熱(re)感(gan)應器與電(dian)磁(ci)(ci)線圈組合轉換為高頻(pin)交變磁(ci)(ci)場，交變磁(ci)(ci)場的(de)磁(ci)(ci)力線作用到金屬管道上(shang)產生鍋(guo)流，從而快速加熱(re)金屬管道。

電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)的(de)(de)溫(wen)(wen)度(du)調節不(bu)準是(shi)(shi)(shi)(shi)怎么回事？ 電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)系統包括電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)控(kong)制(zhi)器(qi)和(he)電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)圈這兩部(bu)分(fen)，每個行(xing)業中對于(yu)溫(wen)(wen)控(kong)的(de)(de)要求都不(bu)樣(yang)，下面就來(lai)(lai)介(jie)紹電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)如(ru)何達到(dao)精(jing)確是(shi)(shi)(shi)(shi)溫(wen)(wen)控(kong)效果?塑料(liao)(liao)行(xing)業中加(jia)(jia)(jia)熱(re)器(qi)，重要指標(biao)就是(shi)(shi)(shi)(shi)保證機(ji)器(qi)各(ge)溫(wen)(wen)區的(de)(de)溫(wen)(wen)度(du)精(jing)確性，各(ge)種(zhong)塑料(liao)(liao)原(yuan)料(liao)(liao)對于(yu)溫(wen)(wen)度(du)的(de)(de)敏(min)感(gan)性雖然不(bu)樣(yang)，但在(zai)生產(chan)(chan)過(guo)(guo)程中對于(yu)溫(wen)(wen)度(du)精(jing)確性的(de)(de)要求都比較高，很(hen)多塑料(liao)(liao)產(chan)(chan)品要求溫(wen)(wen)度(du)不(bu)能(neng)超過(guo)(guo)±5℃，因此，很(hen)多種(zhong)類的(de)(de)塑料(liao)(liao)機(ji)有(you)采用風(feng)冷或水冷進(jin)行(xing)降溫(wen)(wen)控(kong)制(zhi)，否則，加(jia)(jia)(jia)工出來(lai)(lai)的(de)(de)東西可能(neng)不(bu)是(shi)(shi)(shi)(shi)廢(fei)品就是(shi)(shi)(shi)(shi)次品。電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)利用電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)控(kong)制(zhi)板，再配以(yi)(yi)必(bi)要的(de)(de)風(feng)冷、水冷裝置，溫(wen)(wen)度(du)控(kong)制(zhi)可以(yi)(yi)精(jing)確到(dao)±1℃。當然同時也要對塑料(liao)(liao)機(ji)性能(neng)及塑料(liao)(liao)原(yuan)料(liao)(liao)有(you)全面了解及進(jin)行(xing)必(bi)要合理(li)配置。這樣(yang)可以(yi)(yi)降低企(qi)業損耗、提高企(qi)業效益。產(chan)(chan)品性能(neng)穩定、節能(neng)、環保，產(chan)(chan)出的(de)(de)顆粒品質好。

電(dian)磁加熱器IGBT溫度傳感器異(yi)常解(jie)決方法：

1、出現傳(chuan)感器異常后(hou)請先將傳(chuan)感器引(yin)線主板上(shang)拔下，再用(yong)萬(wan)用(yong)表測(ce)量(liang)其阻值，常溫25℃時阻值應(ying)約為10K，否則傳(chuan)感器已損壞(huai)。

2、如傳感器(qi)正(zheng)常，再檢測傳感器(qi)引線(xian)是(shi)(shi)否與(yu)CN3連接正(zheng)常。C36、R16是(shi)(shi)否開、短(duan)路(lu)。

3、檢測U5第16腳是否(fou)連接正(zheng)常。
