電(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)器(qi)是種怎樣的(de)(de)(de)裝(zhuang)置(zhi):電(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)器(qi)是種利用電(dian)(dian)(dian)磁(ci)感應原理將電(dian)(dian)(dian)能(neng)轉(zhuan)換為熱(re)(re)(re)(re)(re)能(neng)的(de)(de)(de)裝(zhuang)置(zhi)。在電(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)器(qi)內(nei)部,由整流電(dian)(dian)(dian)路將50/60Hz的(de)(de)(de)交流電(dian)(dian)(dian)壓(ya)變(bian)成(cheng)直流電(dian)(dian)(dian)壓(ya),再(zai)(zai)經(jing)過(guo)控制電(dian)(dian)(dian)路將直流電(dian)(dian)(dian)壓(ya)轉(zhuan)換成(cheng)頻率為15-20KHz的(de)(de)(de)高(gao)(gao)頻電(dian)(dian)(dian)壓(ya),高(gao)(gao)速(su)變(bian)化的(de)(de)(de)電(dian)(dian)(dian)流流過(guo)線圈會產生高(gao)(gao)速(su)變(bian)化的(de)(de)(de)磁(ci)場(chang),當磁(ci)場(chang)內(nei)的(de)(de)(de)磁(ci)力(li)線通過(guo)金屬(shu)器(qi)皿(min)(min)(導磁(ci)又(you)導電(dian)(dian)(dian)材料(liao))底(di)部金屬(shu)體內(nei)產生無數的(de)(de)(de)小渦(wo)流,使器(qi)皿(min)(min)本身自行高(gao)(gao)速(su)發熱(re)(re)(re)(re)(re),然后再(zai)(zai)加(jia)熱(re)(re)(re)(re)(re)器(qi)皿(min)(min)內(nei)的(de)(de)(de)東西。而電(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)本身對器(qi)皿(min)(min)和(he)器(qi)皿(min)(min)內(nei)的(de)(de)(de)物品的(de)(de)(de)物理性(xing)質和(he)化學性(xing)質不產生任何改(gai)變(bian)。
電磁加熱(re)器(qi)裝(zhuang)置后發(fa)(fa)現溫度超溫怎(zen)樣處理(li),這種現象大多(duo)為注(zhu)塑機, 注(zhu)塑機裝(zhuang)置的電磁加熱(re)器(qi)數量比(bi)較(jiao)多(duo),攪擾也比(bi)較(jiao)嚴重,有時(shi)候發(fa)(fa)現溫度顯現亂(luan)跳,溫度不(bu)穩(wen)守時(shi),能夠選用幾(ji)種辦法測(ce)驗(yan):
第,熱電偶接頭兩(liang)頭能夠并個102P瓷片(pian)電容以消除高頻攪擾。
第(di)二(er),檢查下炮(pao)筒接(jie)地(di)是(shi)不是(shi)杰出(chu)?測驗(yan)炮(pao)筒強行接(jie)地(di)處理。
第三,能(neng)夠(gou)把線圈遠離(li)下熱電偶,減小(xiao)攪擾。
第(di)(di)四(si),測(ce)驗(yan)下用高溫布把熱電(dian)(dian)(dian)偶(ou)包住,讓它不(bu)要與炮筒觸(chu)摸。第(di)(di)五,測(ce)驗(yan)換(huan)條新的熱電(dian)(dian)(dian)偶(ou)。第(di)(di)六,測(ce)驗(yan)下注(zhu)塑(su)機操(cao)控電(dian)(dian)(dian)腦(nao)中心(xin)加個Pai型慮波器,減小(xiao)電(dian)(dian)(dian)源攪擾。
電(dian)(dian)磁(ci)加(jia)熱器,是現今工業域和民用設(she)備中廣泛的(de)種加(jia)熱方式,采用電(dian)(dian)磁(ci)加(jia)熱技術(shu),電(dian)(dian)磁(ci)感應(ying)(ying)加(jia)熱技術(shu)簡稱(cheng)為(wei)(wei)(wei) IH(Induction Heating)技術(shu),是在(zai)法(fa)(fa)拉(la)第(di)感應(ying)(ying)定律的(de)基(ji)礎上發展起來的(de),是法(fa)(fa)拉(la)第(di)感應(ying)(ying)定律的(de)種應(ying)(ying)用形式。其本質就是利用電(dian)(dian)磁(ci)感應(ying)(ying)在(zai)柱(zhu)體內(nei)產生渦流來給加(jia)熱工件的(de)電(dian)(dian)加(jia)熱,它是把電(dian)(dian)能(neng)轉(zhuan)換(huan)為(wei)(wei)(wei)電(dian)(dian)磁(ci)能(neng),再由電(dian)(dian)磁(ci)能(neng)轉(zhuan)換(huan)為(wei)(wei)(wei)電(dian)(dian)能(neng),電(dian)(dian)能(neng)在(zai)金屬內(nei)部轉(zhuan)變為(wei)(wei)(wei)熱能(neng),達(da)到(dao)加(jia)熱金屬的(de)目的(de),從(cong)而杜了明火在(zai)加(jia)熱過程中的(de)危害和干(gan)擾,是種環保(bao),提(ti)倡的(de)加(jia)熱方案。
電(dian)磁加熱器操作(zuo)步驟簡(jian)介:
1、顯示界(jie)面:手動(dong)操作(zuo)的情況:啟動(dong)時:先啟動(dong)水泵,再(zai)(zai)啟動(dong)加熱;停(ting)止時:停(ting)止加熱,再(zai)(zai)停(ting)止水泵。
2、操作(zuo)畫面:自動和(he)手動兩個模(mo)式,可以根據實際(ji)(ji)情況(kuang)切(qie)換;6個溫度(du)(du)區可以根據實際(ji)(ji)情況(kuang)設定溫度(du)(du)。當前值(zhi)為傳感(gan)器側出的實時值(zhi)。
3、運行(xing)設(she)置(zhi):此(ci)界面是在自動(dong)(dong)模(mo)式下的工作狀態。每(mei)周7天(tian)(tian),每(mei)天(tian)(tian)4個時間段,根據(ju)實際情況設(she)定(設(she)置(zhi)此(ci)界面,運行(xing)界面需調為手動(dong)(dong)模(mo)式)。
4、電(dian)磁加(jia)(jia)熱器:該界面(mian)(mian)可(ke)“運行”和“停(ting)止(zhi)”電(dian)磁加(jia)(jia)熱器,同(tong)時可(ke)以觀(guan)察加(jia)(jia)熱器的(de)實時參數6曲(qu)線(xian)。該界面(mian)(mian)主要觀(guan)察6個(ge)溫(wen)度的(de)曲(qu)線(xian)圖,同(tong)時也可(ke)以插上U盤導出各個(ge)溫(wen)度段的(de)參數,放于電(dian)腦(nao)上打印或是觀(guan)看。
5、儀(yi)表配置:主要(yao)是觀看本屏(ping)的些數據,未經(jing)設備廠的協助下不可隨意更改參數。
電磁加熱器經常燒壞的幾個原因(yin):
1、與工(gong)作(zuo)環境(jing)有關:正常來(lai)說(shuo)電磁加(jia)熱控(kong)制器工(gong)作(zuo)環境(jing)般灰(hui)塵較(jiao)多(duo),灰(hui)塵多(duo)了之后,對電磁加(jia)熱控(kong)制主(zhu)板就(jiu)非(fei)常不利。這就(jiu)需要我(wo)們要定期清理(li)電磁加(jia)熱器上灰(hui)塵。其(qi)次就(jiu)是室內(nei)通風要做好(hao),避(bi)免(mian)風扇被卡住(zhu)而起不到主(zhu)板散熱效果(guo)從而使得元器件過熱而燒(shao)壞。
2、與工(gong)作(zuo)時(shi)長(chang)有關:般像家用的電(dian)磁爐每天真正工(gong)作(zuo)時(shi)間(jian)只(zhi)有幾個(ge)小(xiao)時(shi),而諸如塑料機之類的行業(ye)每天天的工(gong)作(zuo)時(shi)間(jian)平均超(chao)過10小(xiao)時(shi),許(xu)多廠家機器的運(yun)作(zuo)時(shi)間(jian)甚至更長(chang),因此,我(wo)們企業(ye)在選購時(shi)定要(yao)看準電(dian)磁加熱控制(zhi)器的質量,購買高質量的電(dian)磁加熱控制(zhi)器,或者合理安排機器運(yun)作(zuo)時(shi)間(jian)。
3、與電磁加熱線(xian)圈(quan)有關:電磁加熱圈(quan)著水(shui)濕(shi)了或者破皮以及(ji)兩線(xian)之間短路等(deng)都是(shi)會造成電磁加熱控制器燒壞。
4、出(chu)現間(jian)題不(bu)要(yao)擅(shan)自處理:整流橋堆損(sun)壞導致跳閘(zha),從而導致電磁加熱(re)控制器燒壞,因此,在遇到電磁加熱(re)設備(bei)在工作時間(jian)突然跳閘(zha)不(bu)要(yao)擅(shan)自處理,定要(yao)聯(lian)系(xi)我們技術(shu)人員來為您解決故障,以避免過度損(sun)壞。
電磁加熱(re)器的全橋(qiao)和(he)半橋(qiao)的工作原理的同異:
、相(xiang)同(tong):均是通過系列電路(lu)處理(li)技術將普通交流(liu)電(220V、380V)轉化成高頻(pin)直(zhi)流(liu)電流(liu),通過做功線盤(pan)產生強烈電渦(wo)流(liu),并與(yu)相(xiang)應專用(yong)(yong)金(jin)屬材質感應產生激烈電磁場,直(zhi)接促使相(xiang)應金(jin)屬材質內部(bu)原子速(su)激蕩碰撞,從(cong)而使得相(xiang)應金(jin)屬材質自身快(kuai)速(su)發熱(re)產生高溫,普遍(bian)用(yong)(yong)于工業塑膠機(ji)(ji)械(xie)料筒(tong)上(shang)加熱(re),如拉絲機(ji)(ji)、吹膜機(ji)(ji),造粒機(ji)(ji),注塑機(ji)(ji),擠出機(ji)(ji)等等!
二、不(bu)同對交(jiao)流電的承接轉化處理技術上:
1、全橋(qiao):采用(yong)雙(shuang)路驅動技(ji)術(shu),利用(yong)雙(shuang)IGBT逆變模塊分別承(cheng)接轉化交流(liu)(liu)電的(de)上玄波(bo)(bo)和(he)下玄波(bo)(bo)電流(liu)(liu),產(chan)生的(de)高頻(pin)電流(liu)(liu)波(bo)(bo)形完整、清晰(xi)、穩定(ding)。
2、半橋:采用(yong)(yong)單路驅(qu)動技術,利(li)用(yong)(yong)單IGBT逆變模塊分別承接(jie)轉化交(jiao)流電(dian)(dian)(dian)的(de)(de)上玄(xuan)(xuan)波(bo),結合相應附加電(dian)(dian)(dian)路配(pei)置吸(xi)收下玄(xuan)(xuan)波(bo)電(dian)(dian)(dian)流進行放電(dian)(dian)(dian)補充,產生的(de)(de)高頻電(dian)(dian)(dian)流波(bo)形(xing)相對完整。
三、對相應專(zhuan)用鍋具的負載感應上:
1、全橋:因電(dian)流(liu)轉化技術配置(zhi)效率高,可負載(zai)較高電(dian)感(gan)負荷,電(dian)轉熱效率相應(ying)較高。
2、半橋:因電流轉化(hua)技(ji)術(shu)配置效率稍低,可(ke)負(fu)載(zai)較低電感負(fu)荷,電轉熱效率相應較低。
電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)對(dui)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)行業(ye)的(de)作用(yong)(yong)(yong):當今世(shi)界(jie)使用(yong)(yong)(yong)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)途徑有(you)三種:燃燒(shao)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)、電(dian)(dian)(dian)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)和(he)其它(ta)能源加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re),當然前兩種是如今主要,也是常用(yong)(yong)(yong)的(de)物料加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)方式。但是電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)方式又比燃燒(shao)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)方式清(qing)潔衛生(sheng)、熱(re)(re)(re)(re)(re)(re)(re)(re)效(xiao)率(lv)高(可(ke)(ke)達85%-95%)、安(an)全(quan)、可(ke)(ke)調(diao)(diao)節(jie)、系統簡便等優點。電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)應(ying)(ying)用(yong)(yong)(yong)域(yu)(yu)廣泛(fan),大致可(ke)(ke)以分(fen)為(wei)民用(yong)(yong)(yong)和(he)工(gong)業(ye)用(yong)(yong)(yong)兩種應(ying)(ying)用(yong)(yong)(yong)域(yu)(yu)。民用(yong)(yong)(yong)域(yu)(yu)主要包括空調(diao)(diao)、洗衣機(ji)(ji)、熱(re)(re)(re)(re)(re)(re)(re)(re)水器(qi)等大家電(dian)(dian)(dian)及豆漿(jiang)機(ji)(ji)、飲水機(ji)(ji)等小家電(dian)(dian)(dian),應(ying)(ying)用(yong)(yong)(yong)于民用(yong)(yong)(yong)域(yu)(yu)的(de)電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)往(wang)(wang)往(wang)(wang)是標準件,單(dan)位價值相對(dui)較低(di)但批量較大;工(gong)業(ye)用(yong)(yong)(yong)域(yu)(yu)主要包括多晶(jing)硅(gui)生(sheng)產、石油天然氣開采、石化化工(gong)等域(yu)(yu),應(ying)(ying)用(yong)(yong)(yong)于工(gong)業(ye)域(yu)(yu)的(de)電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)往(wang)(wang)往(wang)(wang)是工(gong)業(ye)生(sheng)產系統的(de)部(bu)分(fen),是非標準件,對(dui)性能要求高,單(dan)位價值和(he)利(li)潤相對(dui)較高。電(dian)(dian)(dian)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)有(you)使用(yong)(yong)(yong)電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)(re)絲的(de)和(he)電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)。電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)(re)絲初裝成本(ben)低(di),壽(shou)命短,維(wei)護麻煩,耗電(dian)(dian)(dian)量大。而電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器(qi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)效(xiao)率(lv)高,能節(jie)省大量的(de)電(dian)(dian)(dian)能,壽(shou)命長。
