電(dian)磁加熱(re)器的六大使用技巧:

1、在使用(yong)過程(cheng)中,不要輕易(yi)拆除電磁加熱器的(de)接(jie)地導線(xian),因為(wei)接(jie)地措(cuo)施是防止觸電的(de)后(hou)道保護(hu)措(cuo)施。

2、要定期(qi)清理散(san)熱(re)器,保證電磁(ci)加(jia)熱(re)器通風良好。

3、在使(shi)用電磁加熱器時,應先(xian)按說明(ming)書(shu)繞好線圈并(bing)檢(jian)查(cha)無誤后(hou)再接(jie)通電源(yuan)。

4、在(zai)保養(yang)清(qing)洗(xi)電磁(ci)加熱器前切(qie)斷電磁(ci)加熱器的電源。清(qing)潔(jie)電磁(ci)感應加熱器的外(wai)殼時,應用(yong)干(gan)凈的抹布進行擦拭(shi),嚴禁用(yong)噴(pen)射(she)水流沖(chong)洗(xi)外(wai)殼及電器箱部分(fen)。

5、不(bu)要將電(dian)磁加熱器安(an)裝在潮(chao)濕的環境中,防止水蒸汽進入電(dian)箱(xiang)后(hou),易在緣介質表面凝(ning)結,降(jiang)低其緣性能,造成漏電(dian)事(shi)故。

6、要(yao)經常檢查電磁加熱器的進風口及散熱風扇(shan),防(fang)止進風口處(chu)堵塞或(huo)散熱風扇(shan)卡死,避免(mian)因過(guo)熱停機保護。

電(dian)磁加熱器過流(liu),當(dang)電(dian)流(liu)大于120A時,控制器會(hui)自(zi)動檢(jian)測,如(ru)果(guo)連續三次(ci)檢(jian)測均大于120A時顯示(shi)窗(chuang)1會(hui)顯示(shi)“E2”并(bing)閃爍,“過流(liu)”指示(shi)燈會(hui)閃爍提示(shi),蜂鳴音每5秒(miao)短響(xiang)2次(ci)。解決方法:

1、請(qing)確認(ren)線圈電感是否偏(pian)離(li)正常的(de)設計參數(shu)。

2、檢測(ce)R30是否變質(zhi)。

3、可考慮U5是否(fou)損(sun)壞(huai)。

4、這種情況(kuang)通常與線圈參數不合適有(you)很大關系。

電(dian)磁加熱節電(dian)分(fen)析:電(dian)磁加熱器在塑(su)料(liao)機械上(shang)節能30%-70%是怎么(me)來的?

1、相比電阻加(jia)熱(re),電磁加(jia)熱(re)器多了層保溫層,熱(re)能利用率增加(jia)。

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

3、相比電阻(zu)加(jia)(jia)熱,電磁加(jia)(jia)熱器的加(jia)(jia)熱速度要(yao)快四分(fen)之以上,減少(shao)了加(jia)(jia)熱時間。

4、相比(bi)電(dian)阻加(jia)熱(re)(re),電(dian)磁加(jia)熱(re)(re)器的加(jia)熱(re)(re)速(su)度快,生產效率(lv)就提高(gao)(gao)了,讓電(dian)機處(chu)在飽和(he)狀態(tai),使其(qi)減少了,高(gao)(gao)功率(lv)低需求造成的電(dian)能損耗。

此(ci)外,挑(tiao)選(xuan)(xuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)時,還要考(kao)(kao)慮(lv)(lv)(lv)其(qi)(qi)(qi)線(xian)(xian)(xian)(xian)徑,材質,耐(nai)溫耐(nai)壓(ya)性能(neng)等。這(zhe)些也都是(shi)(shi)由(you)其(qi)(qi)(qi)使(shi)(shi)用條(tiao)件決定的(de)(de)(de)(de)(de)(de)。在(zai)實際(ji)選(xuan)(xuan)配(pei)過程中,先要根據加(jia)熱(re)需(xu)求確(que)定所(suo)需(xu)設(she)(she)備功(gong)率(lv)(lv),然后就(jiu)可(ke)以知道其(qi)(qi)(qi)輸(shu)出電(dian)流值,進而確(que)定線(xian)(xian)(xian)(xian)徑、材質,然后視現(xian)場(chang)(chang)(chang)的(de)(de)(de)(de)(de)(de)溫度情(qing)況,散熱(re)情(qing)況等考(kao)(kao)慮(lv)(lv)(lv)其(qi)(qi)(qi)耐(nai)溫性能(neng)。如果(guo)挑(tiao)選(xuan)(xuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)時沒(mei)有(you)考(kao)(kao)慮(lv)(lv)(lv)到(dao)這(zhe)些因(yin)素(su),就(jiu)很(hen)容易出現(xian)設(she)(she)備故障,例如線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)被燒(shao)壞,加(jia)熱(re)效率(lv)(lv)低(di)下(xia),線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)不耐(nai)用等問題。輕則影響生(sheng)產,重則造成(cheng)人身事故。二線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)制:表面(mian)看來,線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)制這(zhe)工(gong)作似乎(hu)是(shi)(shi)沒(mei)技術含(han)量(liang)(liang)的(de)(de)(de)(de)(de)(de),不就(jiu)是(shi)(shi)把(ba)線(xian)(xian)(xian)(xian)材繞(rao)下(xia)組成(cheng)個(ge)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)嘛,這(zhe)誰不會?但實際(ji)上并(bing)沒(mei)有(you)那(nei)么簡(jian)單,線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)(de)(de)繞(rao)制需(xu)要考(kao)(kao)慮(lv)(lv)(lv)到(dao)疊加(jia)、干擾、散熱(re)、距離(li)、感(gan)(gan)量(liang)(liang)匹配(pei)等因(yin)素(su)。不同(tong)(tong)功(gong)率(lv)(lv)的(de)(de)(de)(de)(de)(de)電(dian)磁(ci)(ci)(ci)加(jia)熱(re)器(qi)其(qi)(qi)(qi)所(suo)需(xu)要的(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)電(dian)感(gan)(gan)量(liang)(liang)是(shi)(shi)不樣的(de)(de)(de)(de)(de)(de),只有(you)實際(ji)電(dian)感(gan)(gan)量(liang)(liang)和理(li)論(lun)值直,才(cai)能(neng)保證電(dian)磁(ci)(ci)(ci)加(jia)熱(re)器(qi)的(de)(de)(de)(de)(de)(de)功(gong)率(lv)(lv)大(da)化。例如,臺30KW的(de)(de)(de)(de)(de)(de)電(dian)磁(ci)(ci)(ci)加(jia)熱(re)器(qi),其(qi)(qi)(qi)理(li)論(lun)電(dian)感(gan)(gan)量(liang)(liang)是(shi)(shi)240μH,線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)制時,只有(you)實際(ji)感(gan)(gan)量(liang)(liang)為240μH,其(qi)(qi)(qi)功(gong)率(lv)(lv)才(cai)有(you)可(ke)能(neng)完全達到(dao)。如果(guo)實際(ji)感(gan)(gan)量(liang)(liang)是(shi)(shi)100μH、150μH、300μH、400μH,那(nei)其(qi)(qi)(qi)這(zhe)臺設(she)(she)備的(de)(de)(de)(de)(de)(de)實際(ji)使(shi)(shi)用功(gong)率(lv)(lv)可(ke)能(neng)就(jiu)只有(you)20KW,15KW,甚至根本啟動不了。三適用見場(chang)(chang)(chang):電(dian)磁(ci)(ci)(ci)加(jia)熱(re)器(qi)的(de)(de)(de)(de)(de)(de)廣泛應用性決定了其(qi)(qi)(qi)現(xian)場(chang)(chang)(chang)使(shi)(shi)用情(qing)況的(de)(de)(de)(de)(de)(de)復雜。在(zai)電(dian)磁(ci)(ci)(ci)加(jia)熱(re)器(qi)眾多的(de)(de)(de)(de)(de)(de)使(shi)(shi)用域中,食(shi)品、塑料、化工(gong)、印刷(shua)、供暖、垃(la)圾處理(li),每個(ge)行業的(de)(de)(de)(de)(de)(de)應用場(chang)(chang)(chang)景都不同(tong)(tong),就(jiu)是(shi)(shi)同(tong)(tong)個(ge)行業中,每個(ge)客戶的(de)(de)(de)(de)(de)(de)使(shi)(shi)用現(xian)場(chang)(chang)(chang)也有(you)很(hen)大(da)的(de)(de)(de)(de)(de)(de)差(cha)別。所(suo)以,電(dian)磁(ci)(ci)(ci)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)不具有(you)普遍適用性,是(shi)(shi)種不同(tong)(tong)使(shi)(shi)用場(chang)(chang)(chang)景有(you)不同(tong)(tong)繞(rao)法的(de)(de)(de)(de)(de)(de)非標配(pei)件。

電磁加(jia)熱器的質量是由什么決(jue)定呢:

、重要元器(qi)件的(de)選擇(ze)。電磁加熱控制器(qi)功率部分核心(xin)元器(qi)件是IGBT模(mo)塊,IGBT的(de)優(you)劣直接影(ying)響到(dao)機器(qi)壽(shou)命長短(duan),建議直接從國內代理商那進貨(huo),否則買到(dao)高仿或者翻新的(de)IGBT模(mo)塊仍然會出現質量問題。

二(er)、主板(ban)的(de)選擇。電磁加(jia)熱(re)控(kong)制器(qi)(qi)的(de)主板(ban)分(fen)為(wei)三部分(fen),電源板(ban)、信(xin)號(hao)板(ban)和驅(qu)動板(ban),要(yao)想保(bao)證機器(qi)(qi)長時間穩定工作,主板(ban)要(yao)有各種(zhong)保(bao)護:過(guo)載、過(guo)流和過(guo)熱(re),電磁加(jia)熱(re)器(qi)(qi)應用現(xian)(xian)場環(huan)境很復雜,比如干擾等,旦出現(xian)(xian)非正(zheng)常情(qing)況(kuang),主板(ban)應該能(neng)很快反(fan)應并保(bao)護機器(qi)(qi),防止非正(zheng)常因素損壞(huai)機器(qi)(qi),特別是IGBT。目前市場上很多所謂(wei)的(de)電磁加(jia)熱(re)器(qi)(qi)廠(chang)家(jia)的(de)主板(ban)并不(bu)是自己開發的(de),而是直接(jie)購買的(de),然后自己組裝(zhuang)的(de),般出現(xian)(xian)問題,就直接(jie)讓客戶(hu)換主板(ban),并不(bu)能(neng)發現(xian)(xian)問題的(de)根源所在(zai)。

三、高(gao)溫線(xian)的(de)(de)(de)(de)(de)(de)(de)選擇。高(gao)溫線(xian)是(shi)(shi)很多客戶(hu)容易忽視的(de)(de)(de)(de)(de)(de)(de)個(ge)(ge)問題,目(mu)前市場上(shang)國標的(de)(de)(de)(de)(de)(de)(de)高(gao)溫線(xian)很難買到,不(bu)要(yao)相信商家的(de)(de)(de)(de)(de)(de)(de)所說(shuo)的(de)(de)(de)(de)(de)(de)(de),定睜大眼睛,不(bu)要(yao)嫌麻煩,從重量(liang)和(he)材質上(shang)鑒定下是(shi)(shi)否(fou)是(shi)(shi)國標高(gao)溫線(xian),如果(guo)用(yong)到非標高(gao)溫線(xian),不(bu)僅僅影(ying)響機器(qi)(qi)(qi)壽(shou)命,還會(hui)影(ying)響整機的(de)(de)(de)(de)(de)(de)(de)效(xiao)率,大家應該重視這個(ge)(ge)問題。四經驗(yan)的(de)(de)(de)(de)(de)(de)(de)差別(bie)。電(dian)(dian)磁(ci)(ci)(ci)加熱(re)(re)器(qi)(qi)(qi)安裝的(de)(de)(de)(de)(de)(de)(de)好(hao),和(he)安裝的(de)(de)(de)(de)(de)(de)(de)不(bu)好(hao)效(xiao)果(guo)是(shi)(shi)很大區別(bie),這點需(xu)要(yao)豐(feng)富的(de)(de)(de)(de)(de)(de)(de)安裝實例,光靠幾組數(shu)據(ju)是(shi)(shi)分析不(bu)出(chu)來的(de)(de)(de)(de)(de)(de)(de),根本沒(mei)有(you)這樣的(de)(de)(de)(de)(de)(de)(de)經驗(yan)來支撐,完全靠理論(lun)在安裝。人家說(shuo)臺同型號的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)磁(ci)(ci)(ci)加熱(re)(re)器(qi)(qi)(qi),裝在同型號的(de)(de)(de)(de)(de)(de)(de)注塑機上(shang),為(wei)什(shen)么個(ge)(ge)省電(dian)(dian)40%以上(shang),個(ge)(ge)剛剛夠理論(lun)數(shu)據(ju)的(de)(de)(de)(de)(de)(de)(de)30%,這個(ge)(ge)不(bu)僅是(shi)(shi)機器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)差異,電(dian)(dian)磁(ci)(ci)(ci)加熱(re)(re)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)安裝位置,線(xian)圈長(chang)短都有(you)影(ying)響,如果(guo)是(shi)(shi)采用(yong)多組小功率的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)磁(ci)(ci)(ci)加熱(re)(re)器(qi)(qi)(qi),這個(ge)(ge)差異就更(geng)為(wei)明顯(xian)。電(dian)(dian)磁(ci)(ci)(ci)加熱(re)(re)行業有(you)個(ge)(ge)測試機器(qi)(qi)(qi)是(shi)(shi)否(fou)裝好(hao)的(de)(de)(de)(de)(de)(de)(de)方法,就是(shi)(shi)讓電(dian)(dian)磁(ci)(ci)(ci)加熱(re)(re)器(qi)(qi)(qi)工作2分鐘左右(you),休息1分鐘左右(you)。

普(pu)通加(jia)(jia)熱(re)圈(quan)加(jia)(jia)熱(re)方式:接觸式熱(re)傳遞加(jia)(jia)熱(re):

1、耗電的 30-70% 轉化為工作熱(re)能。

2、加熱通(tong)過接(jie)觸(chu)方(fang)式傳遞熱能。

3、加熱及冷卻都有(you)慣性現象產(chan)生,及升溫降溫都緩慢。

4、加熱有死角,不(bu)能完全包裹(guo)在(zai)料筒外層。

5、加(jia)熱圈(quan)損耗大,壽(shou)命短。

電磁加熱(re)(re)的(de)(de)(de)優勢:不(bu)直接(jie)接(jie)觸(chu)產(chan)(chan)品(pin),不(bu)會和金屬發(fa)(fa)生反(fan)應(ying)(如銅(tong)、鋁、鎳、不(bu)銹鋼(gang)等(deng)),也不(bu)會發(fa)(fa)出任何(he)氣體,環保無毒,且設計了過(guo)流(liu)(liu)、短路(lu)(lu)、缺相、過(guo)壓(ya)、欠壓(ya)、過(guo)熱(re)(re)、線圈開(kai)(kai)路(lu)(lu)、抗干擾、防雷擊等(deng)多項(xiang)自動保護功能,不(bu)會發(fa)(fa)生短路(lu)(lu)。電磁加熱(re)(re)裝(zhuang)置很好(hao)地結合(he)了加熱(re)(re)設備應(ying)用環境和工(gong)作需要進行開(kai)(kai)發(fa)(fa),對食品(pin)機械無需太多改動,便能輕松達到節能30-50%的(de)(de)(de)效果(guo),并能節省預熱(re)(re)時(shi)間,預熱(re)(re)時(shi)間通常縮減到1/3左右(you)。具備節能降耗,精確控溫,可靠安全等(deng)三(san)大特點。電磁加熱(re)(re)的(de)(de)(de)原(yuan)理(li)是(shi)通過(guo)電子(zi)線路(lu)(lu)板組成部(bu)分(fen)產(chan)(chan)生交變磁場、當用含(han)鐵(tie)(tie)質容(rong)器(qi)(qi)放置上面(mian)時(shi),容(rong)器(qi)(qi)表(biao)面(mian)具即(ji)切割交變磁力線而在容(rong)器(qi)(qi)底部(bu)金屬部(bu)分(fen)產(chan)(chan)生交變的(de)(de)(de)電流(liu)(liu)(即(ji)渦流(liu)(liu)),渦流(liu)(liu)使容(rong)器(qi)(qi)底部(bu)的(de)(de)(de)鐵(tie)(tie)原(yuan)子(zi)高(gao)速(su)無規則(ze)運動,原(yuan)子(zi)互相碰撞、摩擦而產(chan)(chan)生熱(re)(re)能。從而起(qi)到加熱(re)(re)物品(pin)的(de)(de)(de)效果(guo)。
