電磁加熱節電分(fen)析：電磁加熱器在塑料(liao)機械上節能30%-70%是(shi)怎么來的？

1、相比電阻(zu)加(jia)熱，電磁加(jia)熱器多了層(ceng)保溫(wen)層(ceng)，熱能利(li)用率增加(jia)。

2、相比電(dian)阻加熱(re)，電(dian)磁加熱(re)器直接作(zuo)用于料管(guan)加熱(re)，減少了熱(re)傳遞熱(re)能損耗。

3、相比電阻加熱(re)(re)，電磁加熱(re)(re)器的加熱(re)(re)速度(du)要快(kuai)四(si)分之以上，減少(shao)了加熱(re)(re)時間。

4、相比電(dian)阻加(jia)熱，電(dian)磁加(jia)熱器的加(jia)熱速(su)度(du)快，生產(chan)效(xiao)率就提高(gao)了，讓(rang)電(dian)機(ji)處在飽和狀態，使其減少了，高(gao)功率低需求(qiu)造成的電(dian)能損(sun)耗(hao)。

電(dian)磁加熱調節(jie)溫度控(kong)制(zhi)方式(shi)：

1、臺電磁加熱器控制(zhi)段溫度。

2、多臺(tai)電磁(ci)加熱器(qi)用個(ge)溫控器(qi)開關(guan)控制。

3、繼電器控制。

4、如(ru)果加熱水的話還(huan)可以用流速控制溫度。

5、分時間控制。

電(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)裝(zhuang)置后溫度(du)不(bu)達標處理方法，當(dang)造粒機類似(si)大功率(lv)(lv)時，安(an)裝(zhuang)電(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)后，溫度(du)總達不(bu)到。電(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)也直(zhi)工(gong)作(zuo)，電(dian)流(liu)(liu)也正常，但溫度(du)總上不(bu)去。般情況(kuang)是(shi)功率(lv)(lv)不(bu)夠大。可以加(jia)(jia)大實(shi)際(ji)功率(lv)(lv)來實(shi)現。要是(shi)確(que)定實(shi)際(ji)功率(lv)(lv)不(bu)小了，這是(shi)由炮筒(tong)(tong)的(de)材(cai)料引起的(de)，不(bu)同(tong)(tong)材(cai)質的(de)在不(bu)同(tong)(tong)的(de)工(gong)作(zuo)頻(pin)率(lv)(lv)時吸收熱(re)量也不(bu)同(tong)(tong)。應該嘗試增加(jia)(jia)諧(xie)振電(dian)容(rong)容(rong)量，讓Q值增加(jia)(jia)，提高(gao)(gao)線圈高(gao)(gao)頻(pin)電(dian)流(liu)(liu)。可以使(shi)炮筒(tong)(tong)內(nei)外溫度(du)均勻來達到提高(gao)(gao)炮筒(tong)(tong)的(de)溫度(du)。條件允話(hua)的(de)話(hua)，可以換掉炮筒(tong)(tong)試試。

電磁感應加(jia)熱器應用超溫怎么辦：

1、熱電偶接(jie)頭兩(liang)端可以并個102P瓷(ci)片電容以消除高(gao)頻(pin)干擾。

2、檢查(cha)下炮筒(tong)接地(di)是(shi)否(fou)良好？嘗試炮筒(tong)強制接地(di)處理。

3、可以把(ba)線(xian)圈遠離下熱電偶，減(jian)小干擾(rao)。

4、嘗試下(xia)用高溫布把熱電偶包住，讓它不要與炮筒接(jie)觸。

5、嘗試換(huan)條新的熱電偶。

6、嘗試下注塑機控制電腦中(zhong)心加個Pai型慮波器，減小(xiao)電源干擾。

電磁加熱器IGBT溫度傳(chuan)感器異(yi)常解決方法：

1、出現傳感(gan)(gan)器異常后請先將傳感(gan)(gan)器引線主板上拔下，再用萬(wan)用表(biao)測(ce)量其阻值(zhi)(zhi)，常溫25℃時阻值(zhi)(zhi)應約為10K，否則傳感(gan)(gan)器已損壞。

2、如傳感(gan)器正常，再(zai)檢(jian)測傳感(gan)器引線是否(fou)(fou)與CN3連接正常。C36、R16是否(fou)(fou)開、短路(lu)。

3、檢測U5第(di)16腳(jiao)是否連(lian)接正常。

電磁(ci)加熱器的質量(liang)是由什么決(jue)定呢：

、重要元器件的選擇。電磁加熱控制器功率部(bu)分核心元器件是IGBT模塊(kuai)，IGBT的優(you)劣(lie)直接影響到機器壽命長(chang)短(duan),建議直接從(cong)國內(nei)代理商那(nei)進(jin)貨，否則買(mai)到高仿或者翻新的IGBT模塊(kuai)仍然會出(chu)現(xian)質(zhi)量問題。

二、主板(ban)(ban)(ban)的(de)選擇。電磁(ci)加(jia)熱控(kong)制器的(de)主板(ban)(ban)(ban)分(fen)為(wei)三(san)部(bu)分(fen)，電源(yuan)板(ban)(ban)(ban)、信號板(ban)(ban)(ban)和驅(qu)動板(ban)(ban)(ban)，要想保證機器長時間(jian)穩(wen)定工作，主板(ban)(ban)(ban)要有各種保護(hu)：過載、過流(liu)和過熱，電磁(ci)加(jia)熱器應用現(xian)場(chang)環境(jing)很(hen)復(fu)雜(za)，比(bi)如干擾等，旦出現(xian)非正(zheng)常情況，主板(ban)(ban)(ban)應該(gai)能(neng)很(hen)快反應并(bing)保護(hu)機器，防止非正(zheng)常因(yin)素損(sun)壞機器，特別是(shi)(shi)IGBT。目前(qian)市場(chang)上很(hen)多所謂的(de)電磁(ci)加(jia)熱器廠家的(de)主板(ban)(ban)(ban)并(bing)不是(shi)(shi)自己(ji)開發的(de)，而是(shi)(shi)直接(jie)購買(mai)的(de)，然后自己(ji)組裝的(de)，般出現(xian)問(wen)題(ti)，就直接(jie)讓客戶換主板(ban)(ban)(ban)，并(bing)不能(neng)發現(xian)問(wen)題(ti)的(de)根(gen)源(yuan)所在。

三、高(gao)溫(wen)(wen)線的(de)(de)選(xuan)擇。高(gao)溫(wen)(wen)線是很多客戶容易忽(hu)視的(de)(de)個(ge)(ge)(ge)問題(ti)，目前市場上(shang)(shang)國標(biao)的(de)(de)高(gao)溫(wen)(wen)線很難(nan)買到(dao)，不要相信商家的(de)(de)所說的(de)(de)，定(ding)睜大(da)眼睛(jing)，不要嫌(xian)麻煩，從(cong)重量(liang)和材質上(shang)(shang)鑒定(ding)下是否是國標(biao)高(gao)溫(wen)(wen)線，如果(guo)用(yong)到(dao)非標(biao)高(gao)溫(wen)(wen)線，不僅僅影響機(ji)(ji)器(qi)(qi)(qi)壽命，還會影響整機(ji)(ji)的(de)(de)效率，大(da)家應該重視這個(ge)(ge)(ge)問題(ti)。四經驗的(de)(de)差別(bie)。電(dian)磁加(jia)(jia)(jia)熱(re)器(qi)(qi)(qi)安裝(zhuang)的(de)(de)好(hao)(hao)，和安裝(zhuang)的(de)(de)不好(hao)(hao)效果(guo)是很大(da)區別(bie)，這點需要豐富(fu)的(de)(de)安裝(zhuang)實例，光(guang)靠幾組數(shu)據是分析不出(chu)來的(de)(de)，根本(ben)沒有(you)這樣的(de)(de)經驗來支撐，完全(quan)靠理(li)論在(zai)安裝(zhuang)。人家說臺(tai)同(tong)型號的(de)(de)電(dian)磁加(jia)(jia)(jia)熱(re)器(qi)(qi)(qi)，裝(zhuang)在(zai)同(tong)型號的(de)(de)注塑(su)機(ji)(ji)上(shang)(shang)，為(wei)什么個(ge)(ge)(ge)省(sheng)電(dian)40%以上(shang)(shang)，個(ge)(ge)(ge)剛(gang)(gang)剛(gang)(gang)夠理(li)論數(shu)據的(de)(de)30%，這個(ge)(ge)(ge)不僅是機(ji)(ji)器(qi)(qi)(qi)的(de)(de)差異，電(dian)磁加(jia)(jia)(jia)熱(re)器(qi)(qi)(qi)的(de)(de)安裝(zhuang)位置，線圈長(chang)短(duan)都有(you)影響，如果(guo)是采(cai)用(yong)多組小功率的(de)(de)電(dian)磁加(jia)(jia)(jia)熱(re)器(qi)(qi)(qi)，這個(ge)(ge)(ge)差異就(jiu)更為(wei)明顯(xian)。電(dian)磁加(jia)(jia)(jia)熱(re)行業有(you)個(ge)(ge)(ge)測試機(ji)(ji)器(qi)(qi)(qi)是否裝(zhuang)好(hao)(hao)的(de)(de)方(fang)法，就(jiu)是讓電(dian)磁加(jia)(jia)(jia)熱(re)器(qi)(qi)(qi)工作(zuo)2分鐘左右，休息1分鐘左右。

電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)對(dui)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)行業(ye)的作(zuo)用(yong)(yong)(yong)：當今世界使用(yong)(yong)(yong)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)的途徑有三種(zhong)：燃燒加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)、電(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)和(he)其(qi)它能源加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)，當然前兩種(zhong)是(shi)如今主要，也是(shi)常(chang)用(yong)(yong)(yong)的物料加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)方式(shi)(shi)。但是(shi)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)方式(shi)(shi)又比燃燒加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)方式(shi)(shi)清潔衛生、熱(re)(re)(re)(re)(re)(re)(re)效率高(gao)(可達85%-95%)、安(an)全(quan)、可調節、系統簡便等(deng)優點。電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)應(ying)用(yong)(yong)(yong)域廣泛，大致(zhi)可以分為民(min)用(yong)(yong)(yong)和(he)工業(ye)用(yong)(yong)(yong)兩種(zhong)應(ying)用(yong)(yong)(yong)域。民(min)用(yong)(yong)(yong)域主要包括空(kong)調、洗衣機(ji)、熱(re)(re)(re)(re)(re)(re)(re)水器(qi)(qi)等(deng)大家(jia)電(dian)(dian)(dian)(dian)及豆漿(jiang)機(ji)、飲水機(ji)等(deng)小家(jia)電(dian)(dian)(dian)(dian)，應(ying)用(yong)(yong)(yong)于(yu)民(min)用(yong)(yong)(yong)域的電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)往(wang)(wang)往(wang)(wang)是(shi)標(biao)準(zhun)件(jian)，單位價(jia)值相對(dui)較低(di)但批量(liang)較大;工業(ye)用(yong)(yong)(yong)域主要包括多晶硅(gui)生產、石油天然氣開采、石化化工等(deng)域，應(ying)用(yong)(yong)(yong)于(yu)工業(ye)域的電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)往(wang)(wang)往(wang)(wang)是(shi)工業(ye)生產系統的部(bu)分，是(shi)非標(biao)準(zhun)件(jian)，對(dui)性能要求高(gao)，單位價(jia)值和(he)利潤相對(dui)較高(gao)。電(dian)(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)有使用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)絲的和(he)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)。電(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)絲初裝(zhuang)成本低(di)，壽(shou)命短，維護麻煩，耗電(dian)(dian)(dian)(dian)量(liang)大。而電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)器(qi)(qi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)效率高(gao)，能節省大量(liang)的電(dian)(dian)(dian)(dian)能，壽(shou)命長。

此(ci)外(wai)，挑(tiao)選(xuan)線(xian)(xian)圈(quan)(quan)(quan)時(shi)，還要(yao)考(kao)慮(lv)(lv)其(qi)(qi)線(xian)(xian)徑，材質，耐溫(wen)耐壓性能(neng)(neng)等(deng)(deng)(deng)。這(zhe)(zhe)些(xie)也都是(shi)由其(qi)(qi)使(shi)(shi)用(yong)(yong)條(tiao)件(jian)決定(ding)的(de)(de)。在實(shi)(shi)際(ji)選(xuan)配(pei)過程(cheng)中(zhong)，先要(yao)根(gen)據加(jia)(jia)熱(re)需(xu)求確定(ding)所需(xu)設(she)備(bei)功(gong)(gong)(gong)率(lv)，然(ran)后就(jiu)(jiu)可(ke)(ke)以(yi)知道其(qi)(qi)輸出(chu)電(dian)(dian)(dian)流(liu)值，進而(er)確定(ding)線(xian)(xian)徑、材質，然(ran)后視現(xian)場(chang)(chang)(chang)的(de)(de)溫(wen)度情(qing)況，散(san)熱(re)情(qing)況等(deng)(deng)(deng)考(kao)慮(lv)(lv)其(qi)(qi)耐溫(wen)性能(neng)(neng)。如(ru)果挑(tiao)選(xuan)線(xian)(xian)圈(quan)(quan)(quan)時(shi)沒(mei)有(you)(you)(you)(you)考(kao)慮(lv)(lv)到(dao)這(zhe)(zhe)些(xie)因素(su)(su)，就(jiu)(jiu)很(hen)容易(yi)出(chu)現(xian)設(she)備(bei)故(gu)障，例(li)如(ru)線(xian)(xian)圈(quan)(quan)(quan)被燒壞，加(jia)(jia)熱(re)效率(lv)低(di)下，線(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)耐用(yong)(yong)等(deng)(deng)(deng)問題。輕則(ze)影響生(sheng)產，重則(ze)造成人身事故(gu)。二線(xian)(xian)圈(quan)(quan)(quan)繞(rao)制：表面看來，線(xian)(xian)圈(quan)(quan)(quan)繞(rao)制這(zhe)(zhe)工(gong)作(zuo)似乎是(shi)沒(mei)技術含(han)量(liang)的(de)(de)，不(bu)(bu)(bu)就(jiu)(jiu)是(shi)把線(xian)(xian)材繞(rao)下組成個線(xian)(xian)圈(quan)(quan)(quan)嘛，這(zhe)(zhe)誰不(bu)(bu)(bu)會？但實(shi)(shi)際(ji)上并沒(mei)有(you)(you)(you)(you)那么簡(jian)單，線(xian)(xian)圈(quan)(quan)(quan)的(de)(de)繞(rao)制需(xu)要(yao)考(kao)慮(lv)(lv)到(dao)疊加(jia)(jia)、干擾(rao)、散(san)熱(re)、距(ju)離、感量(liang)匹配(pei)等(deng)(deng)(deng)因素(su)(su)。不(bu)(bu)(bu)同(tong)功(gong)(gong)(gong)率(lv)的(de)(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)其(qi)(qi)所需(xu)要(yao)的(de)(de)線(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)(dian)感量(liang)是(shi)不(bu)(bu)(bu)樣的(de)(de)，只有(you)(you)(you)(you)實(shi)(shi)際(ji)電(dian)(dian)(dian)感量(liang)和理(li)(li)(li)論值直，才(cai)能(neng)(neng)保證電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)的(de)(de)功(gong)(gong)(gong)率(lv)大(da)化(hua)。例(li)如(ru)，臺(tai)30KW的(de)(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)，其(qi)(qi)理(li)(li)(li)論電(dian)(dian)(dian)感量(liang)是(shi)240μH，線(xian)(xian)圈(quan)(quan)(quan)繞(rao)制時(shi)，只有(you)(you)(you)(you)實(shi)(shi)際(ji)感量(liang)為(wei)240μH，其(qi)(qi)功(gong)(gong)(gong)率(lv)才(cai)有(you)(you)(you)(you)可(ke)(ke)能(neng)(neng)完全達到(dao)。如(ru)果實(shi)(shi)際(ji)感量(liang)是(shi)100μH、150μH、300μH、400μH，那其(qi)(qi)這(zhe)(zhe)臺(tai)設(she)備(bei)的(de)(de)實(shi)(shi)際(ji)使(shi)(shi)用(yong)(yong)功(gong)(gong)(gong)率(lv)可(ke)(ke)能(neng)(neng)就(jiu)(jiu)只有(you)(you)(you)(you)20KW，15KW，甚(shen)至根(gen)本(ben)啟(qi)動不(bu)(bu)(bu)了。三(san)適用(yong)(yong)見(jian)場(chang)(chang)(chang)：電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)的(de)(de)廣(guang)泛應用(yong)(yong)性決定(ding)了其(qi)(qi)現(xian)場(chang)(chang)(chang)使(shi)(shi)用(yong)(yong)情(qing)況的(de)(de)復(fu)雜。在電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)器(qi)(qi)眾多(duo)的(de)(de)使(shi)(shi)用(yong)(yong)域中(zhong)，食品、塑料(liao)、化(hua)工(gong)、印刷、供暖、垃圾處(chu)理(li)(li)(li)，每個行(xing)業(ye)的(de)(de)應用(yong)(yong)場(chang)(chang)(chang)景(jing)(jing)都不(bu)(bu)(bu)同(tong)，就(jiu)(jiu)是(shi)同(tong)個行(xing)業(ye)中(zhong)，每個客戶的(de)(de)使(shi)(shi)用(yong)(yong)現(xian)場(chang)(chang)(chang)也有(you)(you)(you)(you)很(hen)大(da)的(de)(de)差別。所以(yi)，電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)具有(you)(you)(you)(you)普遍適用(yong)(yong)性，是(shi)種不(bu)(bu)(bu)同(tong)使(shi)(shi)用(yong)(yong)場(chang)(chang)(chang)景(jing)(jing)有(you)(you)(you)(you)不(bu)(bu)(bu)同(tong)繞(rao)法的(de)(de)非標配(pei)件(jian)。
