黑龍江60kw電磁加熱器行業報告

電磁加熱(re)器多(duo)溫區控制就是有兩(liang)種:

第(di)種:是臺電磁(ci)加熱控制器控制多組線圈。

第二種:是臺設備使用多(duo)個電磁加(jia)熱控(kong)制器分別(bie)控(kong)制多(duo)個線圈。現在例如(ru)注(zhu)塑機(ji),拉絲機(ji),吹膜(mo)機(ji),擠出機(ji)等機(ji)械設備,料管加(jia)熱部分都(dou)需要幾個不同溫(wen)度(du)才能(neng)滿足(zu)生產,這時(shi)候就要使用到電磁加(jia)熱器多(duo)溫(wen)區來控(kong)制。

第三種:臺電磁加(jia)熱控(kong)制器(qi)控(kong)制多組線圈比較少用,因為如果主機旦出現故障,整個幾(ji)個溫度都將無法加(jia)熱,影響正(zheng)規生產,而且維(wei)護起來也是比較麻煩(fan)的。

第四種:多個電(dian)磁(ci)加熱(re)控制(zhi)(zhi)器(qi)分別控制(zhi)(zhi)獨(du)立線圈(quan),這樣(yang)不但(dan)便于管理,而且加熱(re)非常均勻,維護起來(lai)也是十分方(fang)便的。

電(dian)(dian)磁(ci)(ci)(ci)(ci)加(jia)熱(re)(re)(re)器,是(shi)現今工業域和(he)民用(yong)設備中廣泛(fan)的(de)種(zhong)加(jia)熱(re)(re)(re)方式,采(cai)用(yong)電(dian)(dian)磁(ci)(ci)(ci)(ci)加(jia)熱(re)(re)(re)技(ji)(ji)術(shu),電(dian)(dian)磁(ci)(ci)(ci)(ci)感(gan)應(ying)(ying)(ying)加(jia)熱(re)(re)(re)技(ji)(ji)術(shu)簡稱為 IH(Induction Heating)技(ji)(ji)術(shu),是(shi)在法拉(la)第感(gan)應(ying)(ying)(ying)定律的(de)基礎上發展起(qi)來的(de),是(shi)法拉(la)第感(gan)應(ying)(ying)(ying)定律的(de)種(zhong)應(ying)(ying)(ying)用(yong)形(xing)式。其本質就(jiu)是(shi)利用(yong)電(dian)(dian)磁(ci)(ci)(ci)(ci)感(gan)應(ying)(ying)(ying)在柱體內產生渦(wo)流來給加(jia)熱(re)(re)(re)工件的(de)電(dian)(dian)加(jia)熱(re)(re)(re),它是(shi)把電(dian)(dian)能(neng)轉(zhuan)(zhuan)換為電(dian)(dian)磁(ci)(ci)(ci)(ci)能(neng),再由電(dian)(dian)磁(ci)(ci)(ci)(ci)能(neng)轉(zhuan)(zhuan)換為電(dian)(dian)能(neng),電(dian)(dian)能(neng)在金屬內部轉(zhuan)(zhuan)變為熱(re)(re)(re)能(neng),達到加(jia)熱(re)(re)(re)金屬的(de)目的(de),從而杜了明火在加(jia)熱(re)(re)(re)過(guo)程(cheng)中的(de)危害和(he)干擾(rao),是(shi)種(zhong)環保(bao),提倡的(de)加(jia)熱(re)(re)(re)方案。

電磁加熱器(qi)過(guo)流,當電流大于(yu)120A時(shi),控(kong)制(zhi)器(qi)會(hui)自(zi)動檢測,如果連(lian)續三次檢測均大于(yu)120A時(shi)顯示窗1會(hui)顯示“E2”并(bing)閃(shan)爍,“過(guo)流”指示燈會(hui)閃(shan)爍提示,蜂鳴音每5秒(miao)短響(xiang)2次。解決方法:

1、請確認(ren)線圈(quan)電感(gan)是否偏離正常的設計參(can)數。

2、檢測R30是否變(bian)質(zhi)。

3、可考慮(lv)U5是(shi)否損(sun)壞。

4、這種情況(kuang)通常與線圈參數不合(he)適有很大關系。

電(dian)(dian)磁加(jia)熱器高溫線的(de)選擇(ze)(ze):從(cong)高溫線的(de)外包(bao)裝來看,高溫線般(ban)通(tong)過導體+纖(xian)編(bian)織(zhi)+云母(mu)繞(rao)(rao)(rao)(rao)包(bao)+涂層的(de)組合(he)而成(cheng)。但是(shi)根據(ju)(ju)需(xu)要的(de)不同,會再(zai)添(tian)加(jia)玻纖(xian)編(bian)織(zhi)和云母(mu)繞(rao)(rao)(rao)(rao)包(bao),發生意外的(de)幾率就能(neng)大大的(de)減少。導體需(xu)要根據(ju)(ju)現(xian)場的(de)情(qing)況和工(gong)作的(de)情(qing)況選擇(ze)(ze)高溫線的(de)材質(zhi)是(shi)否(fou)進(jin)行電(dian)(dian)鍍,并且規格也有(you)所(suo)選擇(ze)(ze),根據(ju)(ju)現(xian)場安裝機械選擇(ze)(ze)0.1mm2-0.3mm2的(de)線徑(jing),線徑(jing)越(yue)粗(cu),相對來說再(zai)繞(rao)(rao)(rao)(rao)制(zhi)高線時越(yue)容易固定,但是(shi)不容易扭動;而線徑(jing)細的(de)繞(rao)(rao)(rao)(rao)線比較松散,所(suo)以般(ban)是(shi)考慮繞(rao)(rao)(rao)(rao)制(zhi)方便時采用(yong)。而玻纖(xian)編(bian)織(zhi)主(zhu)要能(neng)起到防磨(mo)和耐(nai)熱作用(yong);云母(mu)是(shi)種高性能(neng)緣制(zhi)品,具有(you)優良的(de)耐(nai)高溫性能(neng)和耐(nai)燃燒(shao)性能(neng);涂層能(neng)夠在起到防腐(fu),耐(nai)磨(mo),隔(ge)熱,緣;所(suo)以在選擇(ze)(ze)時玻纖(xian)編(bian)織(zhi)、云母(mu)和涂層的(de)質(zhi)量也很重要。

此外,挑選(xuan)線(xian)(xian)(xian)圈(quan)(quan)(quan)時(shi),還要考(kao)慮(lv)其(qi)線(xian)(xian)(xian)徑,材(cai)(cai)質,耐(nai)溫耐(nai)壓性能等(deng)(deng)(deng)。這些也都是(shi)(shi)由(you)其(qi)使(shi)用(yong)(yong)(yong)條件(jian)決(jue)定(ding)的(de)(de)(de)。在實際(ji)(ji)(ji)(ji)選(xuan)配(pei)過程中(zhong),先(xian)要根(gen)據加(jia)(jia)熱(re)需(xu)求(qiu)確定(ding)所(suo)需(xu)設(she)備(bei)(bei)功(gong)(gong)率,然(ran)后就(jiu)(jiu)可(ke)以知道其(qi)輸出電(dian)(dian)(dian)流值(zhi),進(jin)而確定(ding)線(xian)(xian)(xian)徑、材(cai)(cai)質,然(ran)后視現(xian)場的(de)(de)(de)溫度(du)情況(kuang)(kuang)(kuang),散熱(re)情況(kuang)(kuang)(kuang)等(deng)(deng)(deng)考(kao)慮(lv)其(qi)耐(nai)溫性能。如(ru)果挑選(xuan)線(xian)(xian)(xian)圈(quan)(quan)(quan)時(shi)沒(mei)(mei)有(you)考(kao)慮(lv)到(dao)這些因素,就(jiu)(jiu)很容易出現(xian)設(she)備(bei)(bei)故障,例如(ru)線(xian)(xian)(xian)圈(quan)(quan)(quan)被燒壞,加(jia)(jia)熱(re)效率低下(xia),線(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)耐(nai)用(yong)(yong)(yong)等(deng)(deng)(deng)問題。輕則影響生產,重則造成人身事故。二線(xian)(xian)(xian)圈(quan)(quan)(quan)繞制(zhi)(zhi):表面(mian)看來,線(xian)(xian)(xian)圈(quan)(quan)(quan)繞制(zhi)(zhi)這工(gong)作似乎是(shi)(shi)沒(mei)(mei)技術(shu)含(han)量(liang)(liang)(liang)的(de)(de)(de),不(bu)(bu)就(jiu)(jiu)是(shi)(shi)把(ba)線(xian)(xian)(xian)材(cai)(cai)繞下(xia)組成個線(xian)(xian)(xian)圈(quan)(quan)(quan)嘛,這誰不(bu)(bu)會?但(dan)實際(ji)(ji)(ji)(ji)上并沒(mei)(mei)有(you)那么簡單,線(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)繞制(zhi)(zhi)需(xu)要考(kao)慮(lv)到(dao)疊加(jia)(jia)、干擾、散熱(re)、距(ju)離(li)、感(gan)量(liang)(liang)(liang)匹配(pei)等(deng)(deng)(deng)因素。不(bu)(bu)同(tong)(tong)功(gong)(gong)率的(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)其(qi)所(suo)需(xu)要的(de)(de)(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)(dian)感(gan)量(liang)(liang)(liang)是(shi)(shi)不(bu)(bu)樣的(de)(de)(de),只(zhi)(zhi)有(you)實際(ji)(ji)(ji)(ji)電(dian)(dian)(dian)感(gan)量(liang)(liang)(liang)和理(li)論(lun)值(zhi)直,才能保證電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)的(de)(de)(de)功(gong)(gong)率大化。例如(ru),臺(tai)30KW的(de)(de)(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi),其(qi)理(li)論(lun)電(dian)(dian)(dian)感(gan)量(liang)(liang)(liang)是(shi)(shi)240μH,線(xian)(xian)(xian)圈(quan)(quan)(quan)繞制(zhi)(zhi)時(shi),只(zhi)(zhi)有(you)實際(ji)(ji)(ji)(ji)感(gan)量(liang)(liang)(liang)為(wei)240μH,其(qi)功(gong)(gong)率才有(you)可(ke)能完全達到(dao)。如(ru)果實際(ji)(ji)(ji)(ji)感(gan)量(liang)(liang)(liang)是(shi)(shi)100μH、150μH、300μH、400μH,那其(qi)這臺(tai)設(she)備(bei)(bei)的(de)(de)(de)實際(ji)(ji)(ji)(ji)使(shi)用(yong)(yong)(yong)功(gong)(gong)率可(ke)能就(jiu)(jiu)只(zhi)(zhi)有(you)20KW,15KW,甚至(zhi)根(gen)本啟(qi)動不(bu)(bu)了(le)。三適用(yong)(yong)(yong)見場:電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)的(de)(de)(de)廣泛應用(yong)(yong)(yong)性決(jue)定(ding)了(le)其(qi)現(xian)場使(shi)用(yong)(yong)(yong)情況(kuang)(kuang)(kuang)的(de)(de)(de)復雜(za)。在電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)眾(zhong)多的(de)(de)(de)使(shi)用(yong)(yong)(yong)域(yu)中(zhong),食品、塑料、化工(gong)、印刷、供暖(nuan)、垃圾處理(li),每(mei)(mei)個行業(ye)的(de)(de)(de)應用(yong)(yong)(yong)場景都不(bu)(bu)同(tong)(tong),就(jiu)(jiu)是(shi)(shi)同(tong)(tong)個行業(ye)中(zhong),每(mei)(mei)個客戶的(de)(de)(de)使(shi)用(yong)(yong)(yong)現(xian)場也有(you)很大的(de)(de)(de)差(cha)別。所(suo)以,電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)具(ju)有(you)普遍適用(yong)(yong)(yong)性,是(shi)(shi)種不(bu)(bu)同(tong)(tong)使(shi)用(yong)(yong)(yong)場景有(you)不(bu)(bu)同(tong)(tong)繞法的(de)(de)(de)非標配(pei)件(jian)。

電(dian)(dian)(dian)磁(ci)加熱(re)器(qi)(qi)(qi)的(de)溫(wen)度(du)(du)(du)調節不準(zhun)是怎么回事(shi)? 電(dian)(dian)(dian)磁(ci)加熱(re)器(qi)(qi)(qi)系統包括(kuo)電(dian)(dian)(dian)磁(ci)加熱(re)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)(qi)和電(dian)(dian)(dian)磁(ci)加熱(re)圈這兩部分,每個(ge)行(xing)業(ye)中對于(yu)溫(wen)控(kong)(kong)的(de)要求(qiu)都(dou)不樣,下面(mian)就(jiu)來介紹電(dian)(dian)(dian)磁(ci)加熱(re)器(qi)(qi)(qi)如何達到精(jing)確是溫(wen)控(kong)(kong)效果(guo)?塑料(liao)行(xing)業(ye)中加熱(re)器(qi)(qi)(qi),重(zhong)要指標就(jiu)是保(bao)證機器(qi)(qi)(qi)各溫(wen)區的(de)溫(wen)度(du)(du)(du)精(jing)確性,各種塑料(liao)原料(liao)對于(yu)溫(wen)度(du)(du)(du)的(de)敏感性雖然不樣,但在生(sheng)產(chan)(chan)過程中對于(yu)溫(wen)度(du)(du)(du)精(jing)確性的(de)要求(qiu)都(dou)比較高,很(hen)多塑料(liao)產(chan)(chan)品(pin)要求(qiu)溫(wen)度(du)(du)(du)不能(neng)超過±5℃,因(yin)此,很(hen)多種類的(de)塑料(liao)機有采用風(feng)冷或水(shui)冷進行(xing)降溫(wen)控(kong)(kong)制(zhi)(zhi),否則,加工出(chu)來的(de)東(dong)西(xi)可能(neng)不是廢品(pin)就(jiu)是次品(pin)。電(dian)(dian)(dian)磁(ci)加熱(re)器(qi)(qi)(qi)利用電(dian)(dian)(dian)磁(ci)加熱(re)控(kong)(kong)制(zhi)(zhi)板,再配以(yi)必要的(de)風(feng)冷、水(shui)冷裝置(zhi),溫(wen)度(du)(du)(du)控(kong)(kong)制(zhi)(zhi)可以(yi)精(jing)確到±1℃。當然同(tong)時也(ye)要對塑料(liao)機性能(neng)及塑料(liao)原料(liao)有全面(mian)了(le)解及進行(xing)必要合(he)理配置(zhi)。這樣可以(yi)降低企(qi)業(ye)損耗(hao)、提高企(qi)業(ye)效益(yi)。產(chan)(chan)品(pin)性能(neng)穩定、節能(neng)、環保(bao),產(chan)(chan)出(chu)的(de)顆(ke)粒品(pin)質好。

電磁加熱器加熱速(su)度慢和以(yi)下幾個點有關:

1、與生(sheng)產的(de)產量(liang)有關,產量(liang)大的(de),加熱的(de)時間就會比較長。

2、和功率的(de)大小有關,功率小的(de)加熱速(su)度就(jiu)會慢些,功率大的(de)自然就(jiu)快些。

3、和加熱的溫度也有關,溫度要求越高,加熱的時間就會長些。

4、和環(huan)境的(de)溫(wen)度(du)有(you)關,環(huan)境的(de)溫(wen)度(du)非常(chang)低的(de)話,加熱(re)的(de)時間也會長些。

電磁感應加熱器(qi)不加熱原因主要(yao)有(you)以下三點:

1、線路(lu)故(gu)障,沒電(dian)供(gong)及。

2、元件損壞,查找更換。

3、調(diao)整(zheng)不當,重新調(diao)整(zheng)適(shi)當數據。
