此外，挑選(xuan)線(xian)(xian)(xian)(xian)圈(quan)時(shi)，還(huan)要考(kao)慮(lv)其(qi)(qi)線(xian)(xian)(xian)(xian)徑(jing)，材質，耐(nai)溫(wen)(wen)耐(nai)壓性(xing)能(neng)等(deng)。這(zhe)(zhe)些也都是(shi)由其(qi)(qi)使(shi)(shi)用(yong)條件(jian)決(jue)定(ding)(ding)的(de)(de)(de)。在(zai)實(shi)際(ji)(ji)選(xuan)配(pei)過程中，先要根據加(jia)(jia)熱(re)(re)(re)(re)需(xu)求確(que)定(ding)(ding)所(suo)需(xu)設備(bei)功(gong)率，然后(hou)就可以知道(dao)其(qi)(qi)輸(shu)出(chu)電(dian)(dian)(dian)(dian)流值(zhi)(zhi)，進而確(que)定(ding)(ding)線(xian)(xian)(xian)(xian)徑(jing)、材質，然后(hou)視(shi)現(xian)場的(de)(de)(de)溫(wen)(wen)度(du)情(qing)況(kuang)，散熱(re)(re)(re)(re)情(qing)況(kuang)等(deng)考(kao)慮(lv)其(qi)(qi)耐(nai)溫(wen)(wen)性(xing)能(neng)。如(ru)(ru)(ru)果挑選(xuan)線(xian)(xian)(xian)(xian)圈(quan)時(shi)沒有(you)考(kao)慮(lv)到(dao)(dao)這(zhe)(zhe)些因素，就很容易出(chu)現(xian)設備(bei)故障，例如(ru)(ru)(ru)線(xian)(xian)(xian)(xian)圈(quan)被燒壞，加(jia)(jia)熱(re)(re)(re)(re)效率低下，線(xian)(xian)(xian)(xian)圈(quan)不(bu)(bu)(bu)(bu)耐(nai)用(yong)等(deng)問題。輕則影響(xiang)生(sheng)產，重則造成人(ren)身(shen)事故。二線(xian)(xian)(xian)(xian)圈(quan)繞(rao)制：表面(mian)看來，線(xian)(xian)(xian)(xian)圈(quan)繞(rao)制這(zhe)(zhe)工(gong)(gong)作似乎是(shi)沒技術含量的(de)(de)(de)，不(bu)(bu)(bu)(bu)就是(shi)把線(xian)(xian)(xian)(xian)材繞(rao)下組成個線(xian)(xian)(xian)(xian)圈(quan)嘛，這(zhe)(zhe)誰不(bu)(bu)(bu)(bu)會(hui)？但實(shi)際(ji)(ji)上并沒有(you)那么簡單，線(xian)(xian)(xian)(xian)圈(quan)的(de)(de)(de)繞(rao)制需(xu)要考(kao)慮(lv)到(dao)(dao)疊加(jia)(jia)、干(gan)擾(rao)、散熱(re)(re)(re)(re)、距離(li)、感(gan)量匹配(pei)等(deng)因素。不(bu)(bu)(bu)(bu)同(tong)功(gong)率的(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)(re)(re)(re)器其(qi)(qi)所(suo)需(xu)要的(de)(de)(de)線(xian)(xian)(xian)(xian)圈(quan)電(dian)(dian)(dian)(dian)感(gan)量是(shi)不(bu)(bu)(bu)(bu)樣(yang)的(de)(de)(de)，只有(you)實(shi)際(ji)(ji)電(dian)(dian)(dian)(dian)感(gan)量和理(li)論值(zhi)(zhi)直，才(cai)(cai)能(neng)保證(zheng)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)(re)(re)(re)器的(de)(de)(de)功(gong)率大(da)化。例如(ru)(ru)(ru)，臺30KW的(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)(re)(re)(re)器，其(qi)(qi)理(li)論電(dian)(dian)(dian)(dian)感(gan)量是(shi)240μH，線(xian)(xian)(xian)(xian)圈(quan)繞(rao)制時(shi)，只有(you)實(shi)際(ji)(ji)感(gan)量為240μH，其(qi)(qi)功(gong)率才(cai)(cai)有(you)可能(neng)完全達到(dao)(dao)。如(ru)(ru)(ru)果實(shi)際(ji)(ji)感(gan)量是(shi)100μH、150μH、300μH、400μH，那其(qi)(qi)這(zhe)(zhe)臺設備(bei)的(de)(de)(de)實(shi)際(ji)(ji)使(shi)(shi)用(yong)功(gong)率可能(neng)就只有(you)20KW，15KW，甚至根本啟動不(bu)(bu)(bu)(bu)了。三適用(yong)見場：電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)(re)(re)(re)器的(de)(de)(de)廣泛應用(yong)性(xing)決(jue)定(ding)(ding)了其(qi)(qi)現(xian)場使(shi)(shi)用(yong)情(qing)況(kuang)的(de)(de)(de)復雜。在(zai)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)(re)(re)(re)器眾多的(de)(de)(de)使(shi)(shi)用(yong)域中，食品、塑料、化工(gong)(gong)、印(yin)刷、供暖、垃圾處理(li)，每(mei)個行業的(de)(de)(de)應用(yong)場景(jing)都不(bu)(bu)(bu)(bu)同(tong)，就是(shi)同(tong)個行業中，每(mei)個客戶的(de)(de)(de)使(shi)(shi)用(yong)現(xian)場也有(you)很大(da)的(de)(de)(de)差(cha)別(bie)。所(suo)以，電(dian)(dian)(dian)(dian)磁(ci)線(xian)(xian)(xian)(xian)圈(quan)不(bu)(bu)(bu)(bu)具(ju)有(you)普遍(bian)適用(yong)性(xing)，是(shi)種不(bu)(bu)(bu)(bu)同(tong)使(shi)(shi)用(yong)場景(jing)有(you)不(bu)(bu)(bu)(bu)同(tong)繞(rao)法的(de)(de)(de)非標(biao)配(pei)件(jian)。

電(dian)磁(ci)加熱器(qi)日常護理(li)：

1、產(chan)品(pin)是(shi)否正確(que)安(an)裝 。每款電(dian)(dian)磁(ci)加熱(re)(re)器及(ji)電(dian)(dian)磁(ci)加熱(re)(re)圈所要求的保溫棉(mian)的厚(hou)道，繞線的粗細長(chang)度(du)，電(dian)(dian)感值，輸入電(dian)(dian)流值都(dou)是(shi)不同的，定(ding)要按照(zhao)廠家出廠時(shi)安(an)裝說明書為標準(zhun)。以及(ji)每臺(tai)電(dian)(dian)磁(ci)加熱(re)(re)控制板之間(jian)的線圈組間(jian)隔間(jian)距(ju)在10cm以上也是(shi)非(fei)常(chang)重要的，因為靠的太近會相互(hu)影響。只有(you)電(dian)(dian)磁(ci)加熱(re)(re)器安(an)裝在正常(chang)參數范圍內才(cai)能保證(zheng)的長(chang)期穩定(ding)工作(zuo)。

2、車間的(de)(de)環境(jing)包(bao)括粉(fen)塵(chen)，灰(hui)塵(chen)，潮濕度有關。般來(lai)講(jiang)粉(fen)塵(chen)灰(hui)塵(chen)越大，對(dui)電(dian)磁加熱(re)(re)控制主(zhu)(zhu)板越不利。如(ru)果(guo)是粉(fen)塵(chen)灰(hui)塵(chen)比(bi)較大的(de)(de)情況(kuang)下，需要(yao)定期清理電(dian)磁加熱(re)(re)器上的(de)(de)風扇，風冷電(dian)磁加熱(re)(re)器主(zhu)(zhu)要(yao)是散熱(re)(re)，室(shi)內通風要(yao)好，避(bi)免風扇被(bei)卡住而起不到主(zhu)(zhu)板散熱(re)(re)效果(guo)從(cong)而使得元器件過熱(re)(re)而燒壞。

3、產(chan)品的(de)(de)(de)質(zhi)(zhi)量(liang)也有很大關系。如(ru)果是(shi)已經按說明(ming)書(shu)上的(de)(de)(de)參數來安裝，車間粉塵灰塵也不(bu)(bu)大的(de)(de)(de)情(qing)況(kuang)下電(dian)磁加(jia)熱器(qi)還是(shi)經常(chang)出(chu)故(gu)障，那么這(zhe)就是(shi)質(zhi)(zhi)量(liang)方面的(de)(de)(de)問(wen)題了(le)。不(bu)(bu)排除有的(de)(de)(de)廠家(jia)為了(le)降低成本(ben)而采用(yong)便宜的(de)(de)(de)元器(qi)件來做導(dao)致(zhi)產(chan)品質(zhi)(zhi)量(liang)不(bu)(bu)穩定而經常(chang)出(chu)現故(gu)障，另外個原因就是(shi)雖(sui)然用(yong)的(de)(de)(de)元器(qi)件是(shi)好的(de)(de)(de)，但本(ben)身電(dian)路板設計(ji)不(bu)(bu)合理也會導(dao)致(zhi)易出(chu)現故(gu)障。如(ru)果是(shi)質(zhi)(zhi)量(liang)問(wen)題導(dao)致(zhi)的(de)(de)(de)，建議可(ke)以換家(jia)了(le)。

4、對(dui)產品的(de)愛(ai)護(hu)程度(du)。對(dui)于(yu)車間灰(hui)塵粉塵比較大(da)的(de)用(yong)戶(hu)，應該定期用(yong)毛刷刷下(xia)(xia)電(dian)磁加(jia)熱(re)器(qi)(qi)上(shang)(shang)的(de)風扇，與電(dian)磁加(jia)熱(re)線(xian)(xian)圈(quan)(quan)上(shang)(shang)的(de)粉塵，對(dui)于(yu)線(xian)(xian)圈(quan)(quan)不(bu)用(yong)有(you)重物壓住，或割破，不(bu)要經常有(you)水濺到線(xian)(xian)圈(quan)(quan)上(shang)(shang)或電(dian)磁感應加(jia)熱(re)器(qi)(qi)上(shang)(shang)。更(geng)不(bu)要將(jiang)電(dian)磁加(jia)熱(re)器(qi)(qi)暴露在(zai)露天環境(jing)(jing)下(xia)(xia)，因為露天環境(jing)(jing)如果遇到下(xia)(xia)雨天肯定就(jiu)要淋濕，在(zai)未干的(de)情(qing)況(kuang)下(xia)(xia)開(kai)機(ji)就(jiu)會(hui)導(dao)(dao)致壞掉。或者露天環境(jing)(jing)早晨雨露較多，導(dao)(dao)致電(dian)路板潮(chao)濕，未干的(de)情(qing)況(kuang)下(xia)(xia)開(kai)機(ji)也(ye)會(hui)導(dao)(dao)致里面的(de)線(xian)(xian)路短路。

電磁感(gan)應加熱器應用超溫怎(zen)么辦：

1、熱電偶接(jie)頭兩端可(ke)以并個102P瓷(ci)片電容(rong)以消除高頻干擾。

2、檢查下炮筒接(jie)地是否良好？嘗試(shi)炮筒強制接(jie)地處理。

3、可(ke)以把(ba)線(xian)圈遠離下(xia)熱電偶(ou)，減(jian)小干擾(rao)。

4、嘗(chang)試下用(yong)高溫布把熱電(dian)偶包住，讓它不要(yao)與炮筒接觸。

5、嘗試換條新的熱電(dian)偶。

6、嘗試下注(zhu)塑機(ji)控制(zhi)電(dian)腦中心加(jia)個Pai型慮波器，減小電(dian)源干擾。

電磁加熱器(qi)應用(yong)范圍：

3、能源、食品(pin)行(xing)業，如：原油輸送管道的加熱；食品(pin)機(ji)械，如：超(chao)貨機(ji)等(deng)需(xu)要電加熱的設備。

4、大功率商用電磁灶機芯。

5、建(jian)材(cai)(cai)行業，如(ru)：燃(ran)氣管(guan)(guan)生(sheng)產(chan)(chan)線(xian)、塑料(liao)管(guan)(guan)材(cai)(cai)生(sheng)產(chan)(chan)線(xian)、PE塑料(liao)硬(ying)質平網、土工(gong)網機(ji)組、自動中(zhong)空成型機(ji)、PE蜂窩板(ban)生(sheng)產(chan)(chan)線(xian)、單雙壁波紋管(guan)(guan)擠出(chu)(chu)生(sheng)產(chan)(chan)線(xian)、復(fu)合氣墊膜(mo)機(ji)組、PVC硬(ying)管(guan)(guan)、芯層發(fa)泡管(guan)(guan)生(sheng)產(chan)(chan)線(xian)、PP擠出(chu)(chu)透明(ming)片材(cai)(cai)生(sheng)產(chan)(chan)線(xian)、擠出(chu)(chu)聚(ju)苯(ben)乙烯發(fa)泡管(guan)(guan)材(cai)(cai)、PE纏(chan)繞膜(mo)機(ji)組。

6、印刷設備里的干燥加熱。

7、其(qi)它類似行業加熱(re)。

在塑料(liao)制(zhi)品過程中，電磁(ci)加(jia)(jia)熱(re)(re)器隨著功(gong)(gong)率(lv)調節旋轉開關，可以調節電磁(ci)感應(ying)加(jia)(jia)熱(re)(re)器的(de)功(gong)(gong)率(lv)大小，當料(liao)簡溫度達到居里(li)點時(shi)(shi)，電磁(ci)加(jia)(jia)熱(re)(re)控制(zhi)板自(zi)動斷電，可程度減少能(neng)源浪費。所以是(shi)不(bu)需要客戶自(zi)行(xing)去調節功(gong)(gong)率(lv)的(de)，電磁(ci)加(jia)(jia)熱(re)(re)器系(xi)列(lie)產(chan)品，采用電磁(ci)加(jia)(jia)熱(re)(re)原理，具有安全(quan)、、節能(neng)、環(huan)保、省時(shi)(shi)、快(kuai)捷、操作簡便等特點；是(shi)塑料(liao)加(jia)(jia)熱(re)(re)行(xing)業(ye)的(de)理想選(xuan)擇。其特點如下：

1、熱量大(da)、升溫(wen)速度快，使料簡(jian)直接(jie)發熱。

2、節能、省錢(qian)電磁(ci)加熱器(qi)熱效(xiao)率可(ke)達90%以(yi)上，與電阻絲相(xiang)比可(ke)節能30%-80%。

3、安全、電磁加熱器加熱時無明火(huo)，滿足防(fang)(fang)火(huo)要求，可(ke)在防(fang)(fang)火(huo)要求高的場所使(shi)用。

4、綠色、環保(bao)無廢氣、廢渣和噪音(yin)污染，清潔衛(wei)生，綠色環保(bao)，大大改(gai)善(shan)生產車間(jian)的工作(zuo)環境。

5、安(an)裝方便，安(an)要求接(jie)上(shang)電(dian)磁加熱線圈(quan)即(ji)可使(shi)用。使(shi)用隨心所欲。

6、輸(shu)出功率可以靈活(huo)調節，以適應不(bu)同功率大小場合需要。

7、有過熱保護(hu)，防止損壞(huai)IGBT模(mo)塊。

8、加(jia)熱(re)點集中(zhong)，電磁加(jia)熱(re)線圈表(biao)面不發熱(re)。

9、達到設定溫度后，無須調節，輸出功率(lv)自動(dong)降為(wei)零(ling)，節省電能(neng)。
