磁加熱器安(an)裝的要求(qiu)有什(shen)么?

1、電磁加熱(re)器要安裝(zhuang)在不進水(shui)或水(shui)霧、不潮濕(shi)、干(gan)凈的工作環境。

2、電(dian)磁加(jia)熱器如(ru)果安裝(zhuang)在電(dian)柜中，定(ding)要做(zuo)好通(tong)風，保證設備散熱良好。

3、電磁加熱器的風(feng)(feng)扇和(he)進(jin)(jin)風(feng)(feng)口很容易堆積灰(hui)(hui)塵(chen)，平常需(xu)要(yao)檢查和(he)清理(li)灰(hui)(hui)塵(chen)，以(yi)防(fang)風(feng)(feng)扇燒壞(huai)或者進(jin)(jin)風(feng)(feng)口處堵塞，防(fang)止(zhi)加熱器過熱導致機器故障(zhang)。

4、對于功率大的(de)電(dian)磁(ci)加(jia)熱器，380V接(jie)線(xian)(xian)應(ying)按(an)4～6A/mm2安裝，零線(xian)(xian)接(jie)大于1mm2就可以。對于220V電(dian)磁(ci)加(jia)熱器，火(huo)線(xian)(xian)和零線(xian)(xian)同時應(ying)按(an)4～6A/mm2安裝，以保證使用安全(quan)。

電(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)器，是(shi)現(xian)今工(gong)業域(yu)和民(min)用設備中廣泛的(de)種加(jia)(jia)(jia)熱(re)(re)(re)方式，采用電(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)技(ji)術(shu)，電(dian)磁(ci)感(gan)應(ying)加(jia)(jia)(jia)熱(re)(re)(re)技(ji)術(shu)簡(jian)稱為(wei) IH(Induction Heating)技(ji)術(shu)，是(shi)在法拉第(di)感(gan)應(ying)定律(lv)(lv)的(de)基礎上發展起來的(de)，是(shi)法拉第(di)感(gan)應(ying)定律(lv)(lv)的(de)種應(ying)用形式。其本(ben)質(zhi)就(jiu)是(shi)利用電(dian)磁(ci)感(gan)應(ying)在柱(zhu)體內(nei)產生渦流來給加(jia)(jia)(jia)熱(re)(re)(re)工(gong)件的(de)電(dian)加(jia)(jia)(jia)熱(re)(re)(re)，它是(shi)把電(dian)能(neng)(neng)(neng)轉換為(wei)電(dian)磁(ci)能(neng)(neng)(neng)，再由電(dian)磁(ci)能(neng)(neng)(neng)轉換為(wei)電(dian)能(neng)(neng)(neng)，電(dian)能(neng)(neng)(neng)在金(jin)屬內(nei)部轉變為(wei)熱(re)(re)(re)能(neng)(neng)(neng)，達(da)到加(jia)(jia)(jia)熱(re)(re)(re)金(jin)屬的(de)目(mu)的(de)，從而(er)杜(du)了(le)明火在加(jia)(jia)(jia)熱(re)(re)(re)過程中的(de)危害和干擾，是(shi)種環保，提倡(chang)的(de)加(jia)(jia)(jia)熱(re)(re)(re)方案。

電(dian)(dian)(dian)磁(ci)(ci)感應加熱(re)(re)器(qi)(qi)與電(dian)(dian)(dian)磁(ci)(ci)加熱(re)(re)器(qi)(qi)的區(qu)別(bie)？簡單的說，他們實質(zhi)上沒(mei)什么區(qu)別(bie)，都(dou)是(shi)(shi)(shi)電(dian)(dian)(dian)磁(ci)(ci)線圈發熱(re)(re)盤(pan)而(er)(er)已(yi)，并且(qie)加熱(re)(re)的物(wu)質(zhi)是(shi)(shi)(shi)有含鐵(tie)的物(wu)質(zhi)。但是(shi)(shi)(shi)電(dian)(dian)(dian)磁(ci)(ci)感應加熱(re)(re)器(qi)(qi)的加熱(re)(re)原(yuan)(yuan)理是(shi)(shi)(shi)感應加熱(re)(re)電(dian)(dian)(dian)源產生(sheng)的交變電(dian)(dian)(dian)流(liu)通過線圈而(er)(er)產生(sheng)磁(ci)(ci)場(chang)，原(yuan)(yuan)子相互碰撞、摩擦而(er)(er)產生(sheng)熱(re)(re)能(neng)而(er)(er)電(dian)(dian)(dian)磁(ci)(ci)加熱(re)(re)器(qi)(qi)則是(shi)(shi)(shi)利用電(dian)(dian)(dian)磁(ci)(ci)感應加熱(re)(re)器(qi)(qi)的原(yuan)(yuan)理將電(dian)(dian)(dian)能(neng)轉(zhuan)(zhuan)換為(wei)熱(re)(re)能(neng)，將交流(liu)電(dian)(dian)(dian)壓(ya)(ya)轉(zhuan)(zhuan)換成(cheng)直流(liu)電(dian)(dian)(dian)壓(ya)(ya)，再經過控(kong)制(zhi)電(dian)(dian)(dian)路將直流(liu)電(dian)(dian)(dian)壓(ya)(ya)轉(zhuan)(zhuan)換為(wei)高(gao)頻電(dian)(dian)(dian)壓(ya)(ya)等(deng)系列轉(zhuan)(zhuan)換轉(zhuan)(zhuan)成(cheng)磁(ci)(ci)場(chang)而(er)(er)加熱(re)(re)的方式。由于加熱(re)(re)方式不樣(yang)，因此，操(cao)作的方式也是(shi)(shi)(shi)不樣(yang)的。節能(neng)的效果(guo)電(dian)(dian)(dian)磁(ci)(ci)感應加熱(re)(re)器(qi)(qi)會更好。

電磁加(jia)熱(re)器的全橋和半橋的應用表現的同異：

、據各自的電(dian)路原(yuan)理(li)的差別(bie)決定(ding)：相(xiang)同：均可(ke)達到使得相(xiang)應料(liao)筒自身快(kuai)速(su)發(fa)熱(re)產生高溫，用(yong)于加工塑料(liao)的功用(yong)。

二、功率段表現上(shang)不同：

1、全橋：對應(ying)檔位功率分配清晰、明確，反應(ying)迅(xun)速。

2、半橋：對應檔位功率分配較模糊，反應相(xiang)對合理。

三、發熱面表現上：

1、全橋：因(yin)可負載負荷較(jiao)高，發熱面(mian)較(jiao)大(da)、較(jiao)均勻、層次(ci)感能(neng)做到循序遞減(jian)，火焰仿真(zhen)效果明顯(xian)。

2、半橋：因可負載負荷(he)較低，發(fa)熱(re)面較小(xiao)、均勻性稍遜、層次感分明，火焰仿(fang)真(zhen)效(xiao)果稍遜。

電(dian)磁加熱(re)器過(guo)流，當電(dian)流大于120A時，控制器會(hui)(hui)自動檢測(ce)，如(ru)果連(lian)續(xu)三次檢測(ce)均(jun)大于120A時顯示(shi)窗1會(hui)(hui)顯示(shi)“E2”并(bing)閃爍(shuo)，“過(guo)流”指示(shi)燈會(hui)(hui)閃爍(shuo)提示(shi)，蜂鳴音每5秒短響2次。解決方法：

1、請(qing)確認線圈電感是(shi)否偏(pian)離(li)正常的設計參(can)數。

2、檢測R30是否變質。

3、可考慮U5是(shi)否損壞(huai)。

4、這種情況通常與線(xian)圈參數不合適有很(hen)大關系。

電磁加熱調節溫度控制(zhi)方(fang)式(shi)：

1、臺電(dian)磁加熱器控制(zhi)段溫度。

2、多臺電磁加(jia)熱(re)器(qi)用個溫控(kong)器(qi)開關(guan)控(kong)制。

3、繼電器控制。

4、如果加熱水的話還可以用(yong)流速控制溫(wen)度(du)。

5、分時間控制。

電(dian)磁加熱(re)器(qi)的電(dian)流小于(yu)5A時，控制器(qi)會自動檢測，如果連(lian)續超過三次檢測均小于(yu)5A時顯(xian)(xian)示(shi)窗1會顯(xian)(xian)示(shi)“E1”并閃爍，“電(dian)流小”指(zhi)示(shi)燈會閃爍提(ti)示(shi)，蜂(feng)鳴音每(mei)5秒短響次。解(jie)決方法：

1、確認(ren)線(xian)圈是否已正確連(lian)接。

2、檢測(ce)與低頻互(hu)感(gan)器相連(lian)的(de)相線是否正(zheng)常。

3、檢測(ce)低頻互感(gan)器(qi)是否(fou)開、短路。

4、檢測(ce)CN7連接是否(fou)正常。

5、檢測C39、DB1、R30、C41、R19、C40、C42、是否短(duan)路。

6、檢測(ce)DB1、R20、R18是(shi)否開路。

7、檢測U5第18腳(jiao)是否接觸良(liang)好。
