電(dian)磁加熱器注(zhu)意事項:
1、主機要(yao)定期除(chu)塵,般1個月除(chu)次,可(ke)用軟毛刷(shua)或高壓氣槍除(chu)塵,以保(bao)證儀器內部良好的通風環境。
2、如(ru)使(shi)用(yong)環境(jing)是帶有腐蝕性(xing)氣體的地方須噴上(shang)緣清漆。或者用(yong)其它的緣防腐材(cai)料。
3、空氣溫度(du)不能高于50℃。
4、電感量只(zhi)是(shi)應用(yong)的(de)其中個參數而已,具體(ti)要(yao)實測(ce)工作(zuo)頻(pin)率和電流(liu),通過(guo)增(zeng)減線圈(quan)匝(za)數來匹配功率。
電(dian)磁(ci)加(jia)熱(re)(re)(re)的(de)優(you)勢:不直接(jie)接(jie)觸產(chan)品(pin)(pin),不會和(he)金(jin)屬發生(sheng)反(fan)應(如銅、鋁、鎳(nie)、不銹鋼等(deng)),也不會發出任何氣體,環(huan)保(bao)無(wu)毒,且設(she)計了過流(liu)、短路(lu)、缺相(xiang)、過壓(ya)、欠壓(ya)、過熱(re)(re)(re)、線(xian)圈開(kai)路(lu)、抗干擾、防雷(lei)擊等(deng)多項自動(dong)保(bao)護功能,不會發生(sheng)短路(lu)。電(dian)磁(ci)加(jia)熱(re)(re)(re)裝置(zhi)很好(hao)地結合了加(jia)熱(re)(re)(re)設(she)備應用環(huan)境和(he)工作需(xu)要進行開(kai)發,對(dui)食品(pin)(pin)機(ji)械無(wu)需(xu)太多改動(dong),便能輕松(song)達到節能30-50%的(de)效果(guo),并(bing)能節省預熱(re)(re)(re)時間,預熱(re)(re)(re)時間通常(chang)縮減到1/3左右。具備節能降耗,精確控溫,可(ke)靠安全(quan)等(deng)三大特點。電(dian)磁(ci)加(jia)熱(re)(re)(re)的(de)原(yuan)理是通過電(dian)子線(xian)路(lu)板組成(cheng)部分(fen)產(chan)生(sheng)交變(bian)(bian)磁(ci)場(chang)、當(dang)用含鐵(tie)質(zhi)容(rong)(rong)器(qi)放(fang)置(zhi)上(shang)面時,容(rong)(rong)器(qi)表面具即切割交變(bian)(bian)磁(ci)力線(xian)而在容(rong)(rong)器(qi)底部金(jin)屬部分(fen)產(chan)生(sheng)交變(bian)(bian)的(de)電(dian)流(liu)(即渦流(liu)),渦流(liu)使容(rong)(rong)器(qi)底部的(de)鐵(tie)原(yuan)子高速無(wu)規則運動(dong),原(yuan)子互相(xiang)碰撞(zhuang)、摩(mo)擦(ca)而產(chan)生(sheng)熱(re)(re)(re)能。從而起(qi)到加(jia)熱(re)(re)(re)物品(pin)(pin)的(de)效果(guo)。
電(dian)(dian)磁加熱(re)(re)器(qi)(qi)裝置后溫(wen)(wen)度不(bu)(bu)(bu)達標處理(li)方法,當造粒機類似大功(gong)率(lv)時,安裝電(dian)(dian)磁加熱(re)(re)器(qi)(qi)后,溫(wen)(wen)度總達不(bu)(bu)(bu)到(dao)。電(dian)(dian)磁加熱(re)(re)器(qi)(qi)也直工作,電(dian)(dian)流也正常,但溫(wen)(wen)度總上不(bu)(bu)(bu)去(qu)。般情況(kuang)是(shi)(shi)功(gong)率(lv)不(bu)(bu)(bu)夠大。可以加大實(shi)際功(gong)率(lv)來實(shi)現。要是(shi)(shi)確定實(shi)際功(gong)率(lv)不(bu)(bu)(bu)小了,這是(shi)(shi)由炮(pao)(pao)筒的材(cai)料引(yin)起的,不(bu)(bu)(bu)同(tong)材(cai)質的在不(bu)(bu)(bu)同(tong)的工作頻(pin)率(lv)時吸(xi)收(shou)熱(re)(re)量(liang)也不(bu)(bu)(bu)同(tong)。應該嘗試(shi)增(zeng)加諧振電(dian)(dian)容容量(liang),讓Q值(zhi)增(zeng)加,提高線圈(quan)高頻(pin)電(dian)(dian)流。可以使(shi)炮(pao)(pao)筒內外溫(wen)(wen)度均勻來達到(dao)提高炮(pao)(pao)筒的溫(wen)(wen)度。條件允(yun)話(hua)的話(hua),可以換(huan)掉炮(pao)(pao)筒試(shi)試(shi)。
電(dian)(dian)(dian)(dian)磁(ci)加熱器(qi)工(gong)作原理:電(dian)(dian)(dian)(dian)磁(ci)加熱是(shi)利用電(dian)(dian)(dian)(dian)磁(ci)感(gan)應原理將(jiang)電(dian)(dian)(dian)(dian)能轉(zhuan)(zhuan)換(huan)(huan)為(wei)(wei)熱能的(de)(de)能量轉(zhuan)(zhuan)換(huan)(huan)過(guo)程,由整(zheng)(zheng)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)將(jiang)50/60Hz的(de)(de)交(jiao)(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓轉(zhuan)(zhuan)變(bian)(bian)成(cheng)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓,再經過(guo)功(gong)(gong)率控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)路(lu)將(jiang)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓轉(zhuan)(zhuan)換(huan)(huan)成(cheng)頻率為(wei)(wei)20~40kHz的(de)(de)高頻電(dian)(dian)(dian)(dian)壓,當高速變(bian)(bian)化(hua)的(de)(de)交(jiao)(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)通(tong)過(guo)線圈時,線圈會(hui)產生高速變(bian)(bian)化(hua)的(de)(de)磁(ci)場,磁(ci)場內的(de)(de)交(jiao)(jiao)變(bian)(bian)磁(ci)力線通(tong)過(guo)金(jin)屬管(guan)(guan)道(dao)時(導磁(ci)、導電(dian)(dian)(dian)(dian)材(cai)料(liao)),管(guan)(guan)壁(bi)(bi)體(ti)內產生無數的(de)(de)小渦流(liu)(liu)(liu)(liu),使(shi)輸油管(guan)(guan)道(dao)的(de)(de)管(guan)(guan)壁(bi)(bi)本身自(zi)行發(fa)熱與原油進行熱交(jiao)(jiao)換(huan)(huan),達到加熱原油的(de)(de)目的(de)(de)。變(bian)(bian)頻器(qi)是(shi)高頻電(dian)(dian)(dian)(dian)磁(ci)加熱器(qi)的(de)(de)核心(xin)部件,是(shi)利用電(dian)(dian)(dian)(dian)力半導體(ti)器(qi)件的(de)(de)通(tong)斷作用將(jiang)工(gong)頻電(dian)(dian)(dian)(dian)源(yuan)變(bian)(bian)換(huan)(huan)為(wei)(wei)另(ling)頻率的(de)(de)電(dian)(dian)(dian)(dian)能控(kong)(kong)制(zhi)裝置。目前使(shi)用的(de)(de)變(bian)(bian)頻器(qi)主要(yao)采用交(jiao)(jiao)流(liu)(liu)(liu)(liu)—直流(liu)(liu)(liu)(liu)—交(jiao)(jiao)流(liu)(liu)(liu)(liu)方式(shi),先把(ba)工(gong)頻交(jiao)(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)通(tong)過(guo)整(zheng)(zheng)流(liu)(liu)(liu)(liu)器(qi)轉(zhuan)(zhuan)換(huan)(huan)成(cheng)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan),然(ran)后再把(ba)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)轉(zhuan)(zhuan)換(huan)(huan)成(cheng)頻率、電(dian)(dian)(dian)(dian)壓均可(ke)控(kong)(kong)制(zhi)的(de)(de)交(jiao)(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)供給電(dian)(dian)(dian)(dian)動機(ji)。變(bian)(bian)頻器(qi)的(de)(de)電(dian)(dian)(dian)(dian)路(lu)般由整(zheng)(zheng)流(liu)(liu)(liu)(liu)、中(zhong)間(jian)直流(liu)(liu)(liu)(liu)環(huan)節(jie)、逆變(bian)(bian)和控(kong)(kong)制(zhi)4個部分組(zu)成(cheng)。整(zheng)(zheng)流(liu)(liu)(liu)(liu)部分為(wei)(wei)三相(xiang)橋(qiao)(qiao)式(shi)不可(ke)控(kong)(kong)整(zheng)(zheng)流(liu)(liu)(liu)(liu)器(qi),逆變(bian)(bian)部分為(wei)(wei)IGBT三相(xiang)橋(qiao)(qiao)式(shi)逆變(bian)(bian)器(qi)且(qie)輸出為(wei)(wei)PWM波(bo)(bo)形,中(zhong)間(jian)直流(liu)(liu)(liu)(liu)環(huan)節(jie)為(wei)(wei)濾波(bo)(bo)、直流(liu)(liu)(liu)(liu)儲能和緩沖無功(gong)(gong)功(gong)(gong)率。
電(dian)磁(ci)加(jia)(jia)熱(re)器(qi)可以多(duo)溫(wen)(wen)(wen)區(qu)控制嗎(ma)?橡膠(jiao)機多(duo)溫(wen)(wen)(wen)區(qu)加(jia)(jia)熱(re)早些年(nian)常(chang)用(yong)(yong)的(de)莫過(guo)于電(dian)阻加(jia)(jia)熱(re),這種(zhong)加(jia)(jia)熱(re)方式熱(re)效率不高,耗電(dian)量比較大。目前理想的(de)橡膠(jiao)機多(duo)溫(wen)(wen)(wen)區(qu)加(jia)(jia)熱(re)建議采用(yong)(yong)電(dian)磁(ci)加(jia)(jia)熱(re)器(qi)加(jia)(jia)熱(re)設備,通過(guo)電(dian)磁(ci)加(jia)(jia)熱(re)圈(quan)(quan)產生渦流使管(guan)道(dao)(dao)(dao)自身發熱(re)。管(guan)道(dao)(dao)(dao)加(jia)(jia)包層2.5公分的(de)保溫(wen)(wen)(wen)棉,這樣熱(re)量不容易外(wai)散(san)到(dao)空氣。電(dian)磁(ci)加(jia)(jia)熱(re)圈(quan)(quan)的(de)外(wai)部溫(wen)(wen)(wen)度(du)只(zhi)有幾十度(du),工(gong)作室溫(wen)(wen)(wen)也(ye)會(hui)由此而減低。晶星電(dian)子科技有限公司據用(yong)(yong)戶親自測(ce)試,橡膠(jiao)機多(duo)溫(wen)(wen)(wen)區(qu)改(gai)用(yong)(yong)電(dian)磁(ci)加(jia)(jia)熱(re)器(qi)相比電(dian)熱(re)圈(quan)(quan)至(zhi)少省電(dian)在(zai)30%以上(shang),非常(chang)實用(yong)(yong)。橡膠(jiao)機多(duo)溫(wen)(wen)(wen)區(qu)加(jia)(jia)熱(re)般為多(duo)條(tiao)加(jia)(jia)熱(re)管(guan)道(dao)(dao)(dao),條(tiao)管(guan)道(dao)(dao)(dao)使用(yong)(yong)2組或(huo)者(zhe)多(duo)組電(dian)磁(ci)加(jia)(jia)熱(re)器(qi)。實際(ji)要根據橡膠(jiao)機加(jia)(jia)熱(re)管(guan)道(dao)(dao)(dao)尺寸而定。電(dian)磁(ci)加(jia)(jia)熱(re)板使用(yong)(yong)功率般為15kw-20kw電(dian)磁(ci)加(jia)(jia)熱(re)器(qi)。
電磁(ci)加熱(re)器出現故障(zhang)時的處(chu)理(li)方法:
、通(tong)過(guo)故障(zhang)(zhang)代(dai)碼自行解決:正規生產廠家(jia)的電磁(ci)加(jia)熱設備如果出(chu)現故障(zhang)(zhang)都會有相(xiang)應(ying)的故障(zhang)(zhang)代(dai)碼顯示,可以讓用戶(hu)目了然。出(chu)現問題(ti)該就可以根據使(shi)用說明書(shu)上(shang)面的故障(zhang)(zhang)代(dai)碼表找相(xiang)應(ying)的解決方法。當然,這需要(yao)用戶(hu)具備定的專(zhuan)業常(chang)識(shi),就可以采用必(bi)要(yao)的措施自行解決。
二、通過(guo)售(shou)(shou)后(hou)服務(wu)(wu)解(jie)(jie)(jie)決(jue):般正(zheng)規電磁加熱器廠(chang)(chang)家(jia)是(shi)免費保修年的,自(zi)行解(jie)(jie)(jie)決(jue)不了的話,就(jiu)應該(gai)積(ji)與生產廠(chang)(chang)家(jia)或經銷商聯系,通過(guo)廠(chang)(chang)家(jia)的售(shou)(shou)后(hou)服務(wu)(wu)來解(jie)(jie)(jie)決(jue)。好的生產廠(chang)(chang)家(jia)都提供優質的售(shou)(shou)后(hou)服務(wu)(wu),能夠迅速幫(bang)用戶解(jie)(jie)(jie)決(jue)問題。
三、過保(bao)修(xiu)期,售(shou)后服務解(jie)決:還有種(zhong)就是電(dian)磁加熱器的保(bao)修(xiu)期已(yi)過后而出現了(le)故障(zhang),這(zhe)種(zhong)的話(hua)你(ni)到(dao)當時售(shou)賣的電(dian)磁加熱器廠(chang)(chang)家(jia)幫你(ni)維(wei)修(xiu),般合理收取維(wei)修(xiu)費(fei)用(正規廠(chang)(chang)家(jia)不會亂收費(fei)的),但是如果你(ni)不是到(dao)該廠(chang)(chang)家(jia)購買(mai)的也是可以維(wei)修(xiu)的。
在(zai)使用(yong)電磁加熱(re)器時要注意(yi)什(shen)么?
1、使(shi)用程要輕易拆(chai)除電磁加(jia)熱控制板接導線接措施防止觸電道保護措施。
2、要定期清理散熱(re)器保證電磷感應加(jia)熱(re)器通風。
3、使用電磁(ci)加熱器應(ying)先按說明書繞線圈并檢查誤再接通電源。
4、保養(yang)清(qing)洗(xi)電(dian)磁加(jia)(jia)熱器(qi)前切斷電(dian)磁加(jia)(jia)熱器(qi)電(dian)源清(qing)潔電(dian)磁加(jia)(jia)熱器(qi)外殼應用干(gan)凈抹布進行擦拭嚴禁用噴射水流沖洗(xi)外殼及(ji)電(dian)器(qi)箱部(bu)。
5、要電磁加熱器(qi)安(an)裝(zhuang)潮濕環(huan)境(jing)防止水蒸汽進(jin)入電箱易緣介質(zhi)表面凝結降低(di)其緣性能造漏電事故。
6、要經(jing)檢查電磁加熱(re)器進風(feng)(feng)口(kou)及散熱(re)風(feng)(feng)扇防(fang)止進風(feng)(feng)口(kou)處堵(du)塞或散熱(re)風(feng)(feng)扇卡死(si)避免熱(re)停(ting)機保(bao)護。
電(dian)磁(ci)加熱控制器運(yun)用在(zai)反應(ying)釜上有什么優勢呢?
、加(jia)熱(re)升溫時間(jian)(jian)短、能量轉換效率高(gao),該設(she)備采用就(jiu)地電(dian)磁加(jia)熱(re),直接加(jia)熱(re)罐體,減少中(zhong)間(jian)(jian)熱(re)傳遞(di)過程提高(gao)熱(re)效率利用。
二、安(an)裝方(fang)便,次性投(tou)入(ru)成本低,只在原(yuan)反(fan)應(ying)釜加入(ru)電磁感應(ying)器即(ji)可,不(bu)對原(yuan)反(fan)應(ying)釜進行大量的改造(zao)。
三(san)、運行成本低,無(wu)需管道(dao)、鍋(guo)爐、煤場、智能(neng)監控,真(zhen)正實現無(wu)人值守。
四、軟啟動:無啟動沖擊電流,可以有效(xiao)保護設(she)備不受傷(shang)害。
五、安全防爆(bao)、無(wu)明火。線圈溫度(du)在100度(du)以內,加熱(re)部分采用電纜室結構,加熱(re)電纜本(ben)身不會產生熱(re)量(liang)。
六、升溫(wen)速度(du)快,溫(wen)度(du)高(gao),高(gao)可達600度(du)加熱時,加熱介質與電(dian)分離,感應(ying)器本身不(bu)(bu)產(chan)生(sheng)高(gao)溫(wen),不(bu)(bu)產(chan)生(sheng)火花,電(dian)源采用特殊的(de)防(fang)爆(bao)外(wai)殼。
七(qi)、綠色環保,無(wu)任何(he)廢棄物(wu)產生,符合(he)可(ke)持續發展(zhan)戰略。
