電磁加(jia)熱器用于油氣管(guan)道(dao)應(ying)用的特點:

1、熱效高:節能電磁加熱器不需要預熱管(guan)道。

2、不破(po)壞管道保溫(wen)層:由于是感應節能電(dian)磁加熱,磁力線能穿透(tou)保溫(wen)層,改造管單。

3、安全(quan)性高:無明(ming)火,無熱輻射,溫度可(ke)控。

4、操(cao)作方便:在管道上纏上電磁線圈,做好溫度控(kong)溫探頭,調(diao)節控(kong)溫系(xi)統,開機(ji)調(diao)節即可自控(kong)加熱恒溫。

電磁加熱器(qi)的安(an)裝(zhuang)及調(diao)試:電磁加熱器(qi)的安(an)裝(zhuang)及調(diao)試比較簡單:

1、改造(zao)之前,先把設備接線(xian)情況理下,拍照,做記號(以備恢復原狀)。

2、確定控制板或(huo)電柜安裝位(wei)置,以便于確定高溫線引(yin)線長(chang)度。定要跟工(gong)廠(chang)電工(gong)或(huo)班交流,確認。

3、拆線圈測(ce)量功率, 數據要準。 來確定(ding)安裝功率。可以結(jie)合工廠電工,這(zhe)也要拍照,留原始(shi)記錄。

4、量炮筒周(zhou)長(chang), 確定(ding)保溫棉尺(chi)寸(cun),黃蠟板尺(chi)寸(cun),黃蠟板預留探頭孔(kong)(kong),孔(kong)(kong)尺(chi)寸(cun)要(yao)準,確定(ding)每個溫區長(chang)度,固定(ding)。

5、確定高溫線長(chang)度,繞制(zhi)。 要求美(mei)觀。整齊。包括(kuo)間距(ju)大小控制(zhi), 松緊控制(zhi)。 繞完后測量(liang)電感量(liang)大小。 注(zhu)意儀表量(liang)程。

6、接線。確認以(yi)前斷路器電(dian)流表量程,過小(xiao)要換掉。先分別測試,測電(dian)壓,電(dian)流是否正(zheng)常(chang)。有問(wen)題解(jie)決, 沒問(wen)題后在(zai)整機測試。

7、 整理,清理現場。要求利索整潔。

電磁加熱器用薄膜電容的要求和注意事項:

1、耐(nai)壓(ya)(ya)(ya)選擇(ze)不(bu)當:例(li)如,交流輸(shu)入端,380V的(de)(de)線電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya),EMI電(dian)(dian)(dian)(dian)(dian)路用的(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi),三角形接法,部分工程師選擇(ze)MKP-X2 275V.AC (這會(hui)導致電(dian)(dian)(dian)(dian)(dian)容(rong)擊(ji)穿)。例(li)如,LC諧振(zhen)回路,很多(duo)工程師以(yi)為半(ban)橋諧振(zhen)電(dian)(dian)(dian)(dian)(dian)容(rong),耐(nai)壓(ya)(ya)(ya)只是直(zhi)流母線537V的(de)(de)半(ban)即可(實(shi)際上這是嚴重錯(cuo)誤的(de)(de))。國(guo)內的(de)(de)機(ji)芯,有使用的(de)(de)薄膜電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)耐(nai)壓(ya)(ya)(ya)等1200V 1600V 2000V 2500V 3000V 4000V 需要根據自己的(de)(de)實(shi)際電(dian)(dian)(dian)(dian)(dian)路來選擇(ze)。正確的(de)(de)方(fang)式是用示波器(qi)加高壓(ya)(ya)(ya)探頭,實(shi)際測量下機(ji)芯在大(da)功率的(de)(de)時候,諧振(zhen)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)波形。

2、電(dian)(dian)(dian)流選擇(ze)不當:很(hen)多企業(ye)的工程師,研發人(ren)員,對于直流母線支撐(cheng)電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器,LC諧振(zhen)電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器,電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器的電(dian)(dian)(dian)流方面根本(ben)就沒經過(guo)具體計算和(he)實(shi)際測(ce)(ce)量,造成電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器工作溫(wen)(wen)度非常高,大大縮短薄膜電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器的使(shi)用壽命,嚴重的出現短時間就炸(zha)掉電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器了(le)。正確(que)的方式,就是(shi)用電(dian)(dian)(dian)流互(hu)感器測(ce)(ce)量下諧振(zhen)回路的電(dian)(dian)(dian)流值(zhi),還有通過(guo)機子(zi)在(zai)老化的時候測(ce)(ce)測(ce)(ce)電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器的溫(wen)(wen)升是(shi)否正常。

3、接線方(fang)式(shi)不(bu)當:在設計電(dian)磁(ci)加(jia)熱機芯的(de)時候,很多情況下需要多個薄(bo)膜電(dian)容(rong)器并(bing)聯(lian)使用.并(bing)聯(lian)的(de)好處就是可以增加(jia)過流能力,降低溫升.但是并(bing)聯(lian)電(dian)路(lu),大的(de)問(wen)題是過流不(bu)均.由于接線方(fang)式(shi)的(de)不(bu)當,往(wang)往(wang)造成并(bing)聯(lian)的(de)幾只電(dian)容(rong)器,某個位(wei)置的(de)電(dian)容(rong)器溫度高,容(rong)易先壞掉。

工業節能加熱五種方法:

1、電(dian)磁(ci)感應加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)是(shi)利用交(jiao)(jiao)變(bian)電(dian)場(chang)產生交(jiao)(jiao)變(bian)的(de)磁(ci)場(chang),被加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)的(de)物體切割磁(ci)場(chang),產生渦流而(er)自(zi)身加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)。需要電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器、電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)感應線(xian)圈和被加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)的(de)物體組(zu)成個完整的(de)感應加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)系統。雖(sui)然是(shi)新興工(gong)業加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)方式,但經過(guo)這些年電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器生產廠家的(de)努力(li),電(dian)磁(ci)感應加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)的(de)發展快速。在塑料行業、食(shi)口行業等都得到廣泛應用。

2、在(zai)電弧加熱(re)(re)(re)用于(yu)氣體產生幾千上萬度的加熱(re)(re)(re)裝置(zhi)。能加熱(re)(re)(re)超(chao)高溫度,適合實驗(yan)域需(xu)要超(chao)高溫的加熱(re)(re)(re)。

3、利用(yong)液體(ti)的(de)電(dian)阻(zu)加熱(re)。裝液體(ti)裝在個(ge)金(jin)屬(shu)(shu)的(de)容器中(zhong),將金(jin)屬(shu)(shu)的(de)端進行(xing)接(jie)地,再(zai)火線放入裝在金(jin)屬(shu)(shu)容器液體(ti)的(de)適當位(wei)置(zhi)進行(xing)加熱(re)。

4、微(wei)波(bo)(bo)加熱也是種特定范圍的(de)電磁波(bo)(bo)。對(dui)能(neng)(neng)吸(xi)收微(wei)波(bo)(bo)的(de)物質(zhi)能(neng)(neng)引起內部分子振動,而得(de)動比較(jiao)好的(de)加熱,因(yin)為(wei)金屬會反(fan)射微(wei)波(bo)(bo),故微(wei)波(bo)(bo)不能(neng)(neng)加熱金屬。微(wei)波(bo)(bo)因(yin)為(wei)其加熱均勻(yun)速(su)度快,清節無污染。在食(shi)品行業中得(de)到廣泛應用。因(yin)為(wei)微(wei)波(bo)(bo)具有穿運性(xing),注意不要用微(wei)波(bo)(bo)加熱那些外(wai)部不能(neng)(neng)加熱而內部能(neng)(neng)加熱的(de)密封物體。

5、紅外(wai)(wai)加熱(re)線(xian)(xian)(xian)(xian)(xian)屬(shu)于(yu)電磁(ci)波的(de)種,物體振動會(hui)產生(sheng)電磁(ci)波,其中就有紅外(wai)(wai)線(xian)(xian)(xian)(xian)(xian)。紅外(wai)(wai)線(xian)(xian)(xian)(xian)(xian)也是種新興(xing)的(de)加熱(re)方式。它適合加熱(re)容易吸收紅外(wai)(wai)線(xian)(xian)(xian)(xian)(xian)的(de)物體,如(ru)纖維、木材等。不適合加熱(re)表面光(guang)滑而內部緊密的(de)物體,如(ru)金屬(shu)等。紅外(wai)(wai)線(xian)(xian)(xian)(xian)(xian)加熱(re)也因其加熱(re)快速節能性好倍受歡(huan)迎。

電(dian)磁(ci)加熱控制器的(de)兩種啟動方式(shi):般(ban)電(dian)磁(ci)加熱器可以有兩種啟動方式(shi),

種是(shi)軟啟(qi)(qi)動(dong)(dong)方式,另(ling)種是(shi)硬啟(qi)(qi)動(dong)(dong)方法。軟啟(qi)(qi)動(dong)(dong)方法是(shi)用(yong)信(xin)號(hao)(hao)(hao)(hao)線(xian)端接(jie)入+號(hao)(hao)(hao)(hao),另(ling)端接(jie)入號(hao)(hao)(hao)(hao),當接(jie)通后功率(lv)則輸(shu)出(chu),電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)就(jiu)(jiu)正常工作(zuo)加(jia)(jia)(jia)熱(re)(re)(re)(re)。當斷開(kai)信(xin)號(hao)(hao)(hao)(hao)線(xian)后則功率(lv)就(jiu)(jiu)不輸(shu)出(chu),電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)就(jiu)(jiu)停(ting)(ting)止(zhi)(zhi)加(jia)(jia)(jia)熱(re)(re)(re)(re)。這種叫做(zuo)軟啟(qi)(qi)動(dong)(dong)方式,使用(yong)軟啟(qi)(qi)動(dong)(dong)方式控制(zhi)(zhi)電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)的(de)優勢是(shi)控制(zhi)(zhi)電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)方便,可(ke)以(yi)自(zi)由接(jie)入或(huo)斷開(kai)來控制(zhi)(zhi)電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)工作(zuo)或(huo)停(ting)(ting)止(zhi)(zhi)。軟啟(qi)(qi)動(dong)(dong)的(de)另(ling)外頭(tou)接(jie)的(de)是(shi)溫(wen)控器(qi)(qi)或(huo)繼(ji)電(dian)器(qi)(qi),使用(yong)溫(wen)控器(qi)(qi)可(ke)以(yi)利于控制(zhi)(zhi)電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)加(jia)(jia)(jia)熱(re)(re)(re)(re)的(de)溫(wen)度,和調節溫(wen)度的(de)大(da)小。當個(ge)溫(wen)區只有(you)組電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)的(de)時(shi)候,軟啟(qi)(qi)動(dong)(dong)方法只要(yao)要(yao)信(xin)號(hao)(hao)(hao)(hao)線(xian)接(jie)通+號(hao)(hao)(hao)(hao)和號(hao)(hao)(hao)(hao)就(jiu)(jiu)可(ke)以(yi)了(le),當個(ge)溫(wen)區有(you)兩(liang)個(ge)電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)的(de)時(shi)候,就(jiu)(jiu)要(yao)把這兩(liang)個(ge)控制(zhi)(zhi)主(zhu)板(ban)的(de)+號(hao)(hao)(hao)(hao)信(xin)號(hao)(hao)(hao)(hao)線(xian)并(bing)聯,軟啟(qi)(qi)動(dong)(dong)信(xin)號(hao)(hao)(hao)(hao)線(xian)號(hao)(hao)(hao)(hao)并(bing)聯,當控制(zhi)(zhi)+接(jie)通的(de)時(shi)候功率(lv)就(jiu)(jiu)輸(shu)出(chu),電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)就(jiu)(jiu)會正常加(jia)(jia)(jia)熱(re)(re)(re)(re)工作(zuo),當斷開(kai)十接(jie)通,電(dian)磁(ci)(ci)(ci)加(jia)(jia)(jia)熱(re)(re)(re)(re)控制(zhi)(zhi)器(qi)(qi)就(jiu)(jiu)停(ting)(ting)止(zhi)(zhi)加(jia)(jia)(jia)熱(re)(re)(re)(re)。

另種(zhong)啟(qi)動(dong)(dong)方(fang)(fang)式就(jiu)是硬啟(qi)動(dong)(dong)方(fang)(fang)式,就(jiu)是將+號信線固定。但這種(zhong)方(fang)(fang)式不能靈活控(kong)制(zhi)電磁加(jia)熱器(qi)。相對比于硬啟(qi)動(dong)(dong)方(fang)(fang)式來說(shuo),軟啟(qi)動(dong)(dong)方(fang)(fang)式更具有優(you)勢,軟啟(qi)動(dong)(dong)電磁加(jia)熱器(qi)因使用(yong)方(fang)(fang)便,利(li)于控(kong)制(zhi),所(suo)以大多(duo)數都是使用(yong)軟啟(qi)動(dong)(dong)來控(kong)制(zhi)電磁加(jia)熱器(qi)的。

電(dian)磁(ci)(ci)加熱(re)(re)(re)器(qi)是(shi)(shi)種怎(zen)樣的(de)(de)(de)(de)裝置:電(dian)磁(ci)(ci)加熱(re)(re)(re)器(qi)是(shi)(shi)種利用電(dian)磁(ci)(ci)感應原(yuan)理(li)將(jiang)電(dian)能(neng)轉換為熱(re)(re)(re)能(neng)的(de)(de)(de)(de)裝置。在電(dian)磁(ci)(ci)加熱(re)(re)(re)器(qi)內(nei)部(bu),由整流電(dian)路將(jiang)50/60Hz的(de)(de)(de)(de)交(jiao)流電(dian)壓(ya)變成直流電(dian)壓(ya),再經過控制電(dian)路將(jiang)直流電(dian)壓(ya)轉換成頻(pin)率為15-20KHz的(de)(de)(de)(de)高(gao)頻(pin)電(dian)壓(ya),高(gao)速(su)變化的(de)(de)(de)(de)電(dian)流流過線圈(quan)會產生高(gao)速(su)變化的(de)(de)(de)(de)磁(ci)(ci)場,當磁(ci)(ci)場內(nei)的(de)(de)(de)(de)磁(ci)(ci)力(li)線通過金屬器(qi)皿(導磁(ci)(ci)又導電(dian)材料)底(di)部(bu)金屬體內(nei)產生無(wu)數的(de)(de)(de)(de)小渦流,使(shi)器(qi)皿本身(shen)自行(xing)高(gao)速(su)發熱(re)(re)(re),然后(hou)再加熱(re)(re)(re)器(qi)皿內(nei)的(de)(de)(de)(de)東西(xi)。而電(dian)磁(ci)(ci)加熱(re)(re)(re)本身(shen)對(dui)器(qi)皿和器(qi)皿內(nei)的(de)(de)(de)(de)物品的(de)(de)(de)(de)物理(li)性質(zhi)和化學性質(zhi)不產生任何改變。

此(ci)外,挑(tiao)選(xuan)(xuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)時(shi),還要(yao)考(kao)慮(lv)(lv)(lv)其(qi)線(xian)(xian)(xian)(xian)徑,材(cai)質(zhi),耐(nai)溫(wen)耐(nai)壓性能(neng)(neng)等(deng)(deng)(deng)。這(zhe)(zhe)些也(ye)都是(shi)由(you)其(qi)使(shi)用(yong)條件(jian)決定(ding)的(de)(de)。在實(shi)際(ji)(ji)(ji)選(xuan)(xuan)配(pei)過程中,先要(yao)根據加(jia)熱(re)需(xu)求確(que)定(ding)所(suo)需(xu)設備(bei)功(gong)率(lv),然(ran)后就(jiu)可(ke)以知(zhi)道其(qi)輸(shu)出(chu)電(dian)(dian)流值(zhi),進而確(que)定(ding)線(xian)(xian)(xian)(xian)徑、材(cai)質(zhi),然(ran)后視(shi)現(xian)場(chang)的(de)(de)溫(wen)度情況(kuang),散熱(re)情況(kuang)等(deng)(deng)(deng)考(kao)慮(lv)(lv)(lv)其(qi)耐(nai)溫(wen)性能(neng)(neng)。如果(guo)挑(tiao)選(xuan)(xuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)時(shi)沒(mei)(mei)有(you)考(kao)慮(lv)(lv)(lv)到(dao)(dao)這(zhe)(zhe)些因素,就(jiu)很容(rong)易(yi)出(chu)現(xian)設備(bei)故(gu)障,例(li)如線(xian)(xian)(xian)(xian)圈(quan)(quan)被燒壞(huai),加(jia)熱(re)效(xiao)率(lv)低(di)下,線(xian)(xian)(xian)(xian)圈(quan)(quan)不(bu)(bu)(bu)(bu)(bu)(bu)耐(nai)用(yong)等(deng)(deng)(deng)問題(ti)。輕則影響生產,重則造成人身事故(gu)。二線(xian)(xian)(xian)(xian)圈(quan)(quan)繞(rao)(rao)制:表面看來,線(xian)(xian)(xian)(xian)圈(quan)(quan)繞(rao)(rao)制這(zhe)(zhe)工(gong)作似乎是(shi)沒(mei)(mei)技術含(han)量(liang)的(de)(de),不(bu)(bu)(bu)(bu)(bu)(bu)就(jiu)是(shi)把線(xian)(xian)(xian)(xian)材(cai)繞(rao)(rao)下組(zu)成個(ge)線(xian)(xian)(xian)(xian)圈(quan)(quan)嘛,這(zhe)(zhe)誰(shui)不(bu)(bu)(bu)(bu)(bu)(bu)會?但實(shi)際(ji)(ji)(ji)上并沒(mei)(mei)有(you)那么(me)簡單,線(xian)(xian)(xian)(xian)圈(quan)(quan)的(de)(de)繞(rao)(rao)制需(xu)要(yao)考(kao)慮(lv)(lv)(lv)到(dao)(dao)疊(die)加(jia)、干(gan)擾、散熱(re)、距(ju)離、感(gan)(gan)量(liang)匹配(pei)等(deng)(deng)(deng)因素。不(bu)(bu)(bu)(bu)(bu)(bu)同(tong)功(gong)率(lv)的(de)(de)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)其(qi)所(suo)需(xu)要(yao)的(de)(de)線(xian)(xian)(xian)(xian)圈(quan)(quan)電(dian)(dian)感(gan)(gan)量(liang)是(shi)不(bu)(bu)(bu)(bu)(bu)(bu)樣(yang)的(de)(de),只有(you)實(shi)際(ji)(ji)(ji)電(dian)(dian)感(gan)(gan)量(liang)和理論(lun)值(zhi)直(zhi),才能(neng)(neng)保(bao)證電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)的(de)(de)功(gong)率(lv)大(da)(da)化。例(li)如,臺30KW的(de)(de)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi),其(qi)理論(lun)電(dian)(dian)感(gan)(gan)量(liang)是(shi)240μH,線(xian)(xian)(xian)(xian)圈(quan)(quan)繞(rao)(rao)制時(shi),只有(you)實(shi)際(ji)(ji)(ji)感(gan)(gan)量(liang)為(wei)240μH,其(qi)功(gong)率(lv)才有(you)可(ke)能(neng)(neng)完全達到(dao)(dao)。如果(guo)實(shi)際(ji)(ji)(ji)感(gan)(gan)量(liang)是(shi)100μH、150μH、300μH、400μH,那其(qi)這(zhe)(zhe)臺設備(bei)的(de)(de)實(shi)際(ji)(ji)(ji)使(shi)用(yong)功(gong)率(lv)可(ke)能(neng)(neng)就(jiu)只有(you)20KW,15KW,甚至根本啟(qi)動不(bu)(bu)(bu)(bu)(bu)(bu)了。三適用(yong)見場(chang):電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)的(de)(de)廣泛應用(yong)性決定(ding)了其(qi)現(xian)場(chang)使(shi)用(yong)情況(kuang)的(de)(de)復(fu)雜。在電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)眾多的(de)(de)使(shi)用(yong)域中,食品(pin)、塑料、化工(gong)、印刷(shua)、供暖、垃圾處理,每個(ge)行業(ye)的(de)(de)應用(yong)場(chang)景都不(bu)(bu)(bu)(bu)(bu)(bu)同(tong),就(jiu)是(shi)同(tong)個(ge)行業(ye)中,每個(ge)客戶的(de)(de)使(shi)用(yong)現(xian)場(chang)也(ye)有(you)很大(da)(da)的(de)(de)差別(bie)。所(suo)以,電(dian)(dian)磁(ci)(ci)線(xian)(xian)(xian)(xian)圈(quan)(quan)不(bu)(bu)(bu)(bu)(bu)(bu)具有(you)普遍適用(yong)性,是(shi)種不(bu)(bu)(bu)(bu)(bu)(bu)同(tong)使(shi)用(yong)場(chang)景有(you)不(bu)(bu)(bu)(bu)(bu)(bu)同(tong)繞(rao)(rao)法(fa)的(de)(de)非標配(pei)件(jian)。

1、電(dian)磁加熱器要(yao)安裝在不(bu)(bu)進水(shui)或水(shui)霧、不(bu)(bu)潮(chao)濕、干凈的工作環境(jing)。
