電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器對(dui)(dui)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)行業(ye)的作用(yong)(yong)(yong):當(dang)今世界使用(yong)(yong)(yong)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的途徑有三種:燃燒加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)、電(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)和其它能(neng)源(yuan)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re),當(dang)然前(qian)兩種是如今主(zhu)(zhu)要(yao),也是常用(yong)(yong)(yong)的物料加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)方(fang)(fang)式。但(dan)是電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)方(fang)(fang)式又比燃燒加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)方(fang)(fang)式清潔(jie)衛(wei)生(sheng)、熱(re)(re)(re)(re)(re)效率高(gao)(可達85%-95%)、安全、可調(diao)節(jie)、系(xi)(xi)統(tong)簡便等優點。電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器應(ying)用(yong)(yong)(yong)域(yu)廣泛,大(da)(da)(da)致可以分(fen)為民用(yong)(yong)(yong)和工(gong)(gong)業(ye)用(yong)(yong)(yong)兩種應(ying)用(yong)(yong)(yong)域(yu)。民用(yong)(yong)(yong)域(yu)主(zhu)(zhu)要(yao)包括(kuo)空調(diao)、洗衣機、熱(re)(re)(re)(re)(re)水器等大(da)(da)(da)家電(dian)(dian)(dian)及(ji)豆(dou)漿機、飲水機等小(xiao)家電(dian)(dian)(dian),應(ying)用(yong)(yong)(yong)于民用(yong)(yong)(yong)域(yu)的電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器往(wang)(wang)往(wang)(wang)是標(biao)準(zhun)件,單位價值相(xiang)對(dui)(dui)較(jiao)低(di)但(dan)批量(liang)(liang)較(jiao)大(da)(da)(da);工(gong)(gong)業(ye)用(yong)(yong)(yong)域(yu)主(zhu)(zhu)要(yao)包括(kuo)多晶硅生(sheng)產、石油天(tian)然氣(qi)開采、石化化工(gong)(gong)等域(yu),應(ying)用(yong)(yong)(yong)于工(gong)(gong)業(ye)域(yu)的電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器往(wang)(wang)往(wang)(wang)是工(gong)(gong)業(ye)生(sheng)產系(xi)(xi)統(tong)的部(bu)分(fen),是非(fei)標(biao)準(zhun)件,對(dui)(dui)性能(neng)要(yao)求高(gao),單位價值和利潤相(xiang)對(dui)(dui)較(jiao)高(gao)。電(dian)(dian)(dian)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)有使用(yong)(yong)(yong)電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)絲(si)(si)的和電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)。電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)絲(si)(si)初裝(zhuang)成本低(di),壽(shou)命(ming)短,維護麻煩,耗電(dian)(dian)(dian)量(liang)(liang)大(da)(da)(da)。而電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)效率高(gao),能(neng)節(jie)省(sheng)大(da)(da)(da)量(liang)(liang)的電(dian)(dian)(dian)能(neng),壽(shou)命(ming)長(chang)。
如(ru)何選(xuan)擇電磁加(jia)熱器保溫材料?
1、根據材(cai)(cai)料的(de)耐(nai)溫(wen)等,選擇耐(nai)溫(wen)比發熱體(ti)表面的(de)加熱溫(wen)度(du)高(gao)至(zhi)少300度(du)的(de)保溫(wen)材(cai)(cai)料。
2、根據電磁(ci)加(jia)熱(re)控制器(qi)線圈布置(zhi)的(de)面(mian)積(ji)以及線圈與發(fa)熱(re)體的(de)距離,選(xuan)擇(ze)合適導熱(re)系數的(de)保(bao)溫材料(liao)。
3、根據(ju)線圈(quan)成型要求,選擇不(bu)同致密(mi)性和(he)硬度的保溫材料。
4、根據現場的施工條件(jian),選擇適合(he)的保溫材料(liao)。
5、重要的(de)條(tiao)原則,就是(shi)要保證經過上述(shu)選擇后,保溫(wen)棉表面的(de)溫(wen)度(du)在工作過程中,盡可能低。高溫(wen)場合至少要保持在100度(du)以下。
電(dian)磁加熱(re)器多溫區(qu)控制就是(shi)有兩種:
第種:是(shi)臺(tai)電磁加熱控制器(qi)控制多組線(xian)圈(quan)。
第二種(zhong):是臺設(she)備(bei)使用多個電磁加(jia)(jia)熱控(kong)制(zhi)(zhi)器(qi)分別控(kong)制(zhi)(zhi)多個線圈(quan)。現在(zai)例如注塑(su)機(ji)(ji),拉絲機(ji)(ji),吹膜(mo)機(ji)(ji),擠出機(ji)(ji)等機(ji)(ji)械設(she)備(bei),料管加(jia)(jia)熱部分都需要幾(ji)個不同溫(wen)度才(cai)能滿足生產(chan),這時候(hou)就要使用到電磁加(jia)(jia)熱器(qi)多溫(wen)區來控(kong)制(zhi)(zhi)。
第(di)三種:臺電(dian)磁(ci)加熱(re)控制器控制多組線圈比較(jiao)少用,因(yin)為如果(guo)主機旦出(chu)現(xian)故障,整個幾(ji)個溫度(du)都將無法加熱(re),影響正規生產,而(er)且(qie)維(wei)護(hu)起來(lai)也是比較(jiao)麻煩(fan)的。
第四種:多個電磁(ci)加熱控制器(qi)分別控制獨立線圈(quan),這樣(yang)不(bu)但便于管理,而且(qie)加熱非(fei)常均勻,維護起(qi)來也是十分方便的。
電磁(ci)加熱器經常燒壞的幾個(ge)原因:
1、與工作(zuo)(zuo)環(huan)境有關(guan):正(zheng)常來(lai)說電磁加(jia)熱(re)控制器工作(zuo)(zuo)環(huan)境般灰塵(chen)較多(duo),灰塵(chen)多(duo)了之后,對電磁加(jia)熱(re)控制主板(ban)就非常不利。這(zhe)就需要我們要定期清理電磁加(jia)熱(re)器上灰塵(chen)。其次就是室內通風(feng)要做好(hao),避免風(feng)扇被卡(ka)住而起不到主板(ban)散(san)熱(re)效果從而使得元(yuan)器件過熱(re)而燒壞(huai)。
2、與工作(zuo)時長有關(guan):般(ban)像(xiang)家用(yong)的(de)電(dian)磁爐每天真(zhen)正工作(zuo)時間只有幾個小(xiao)時,而諸如塑料機之類(lei)的(de)行業(ye)每天天的(de)工作(zuo)時間平(ping)均超過10小(xiao)時,許多廠家機器(qi)(qi)的(de)運(yun)作(zuo)時間甚至更長,因此,我們企(qi)業(ye)在(zai)選購時定要看準電(dian)磁加熱(re)(re)控制器(qi)(qi)的(de)質量(liang),購買高質量(liang)的(de)電(dian)磁加熱(re)(re)控制器(qi)(qi),或者合理安排機器(qi)(qi)運(yun)作(zuo)時間。
3、與電(dian)(dian)磁加(jia)熱(re)線圈有關(guan):電(dian)(dian)磁加(jia)熱(re)圈著水濕了或者(zhe)破皮以及兩線之間短路等都是會造成電(dian)(dian)磁加(jia)熱(re)控(kong)制器燒壞。
4、出現(xian)間題(ti)不要(yao)擅(shan)自(zi)處(chu)理(li):整流橋堆(dui)損(sun)壞導致跳閘(zha),從而導致電(dian)磁加熱(re)(re)控(kong)制器燒壞,因此,在遇到電(dian)磁加熱(re)(re)設備在工作時間突然跳閘(zha)不要(yao)擅(shan)自(zi)處(chu)理(li),定要(yao)聯系(xi)我(wo)們技術人員來為(wei)您(nin)解決(jue)故障(zhang),以避免(mian)過度損(sun)壞。
電(dian)磁加熱(re)(re)器(qi)的(de)前景:當前世界經濟不(bu)景氣,企(qi)業(ye)(ye)(ye)生(sheng)(sheng)存(cun)壓力(li)大,而塑(su)膠行業(ye)(ye)(ye)競(jing)爭(zheng)激(ji)烈。降低生(sheng)(sheng)產(chan)成本,提高產(chan)品(pin)的(de)競(jing)爭(zheng)力(li),是(shi)每個(ge)企(qi)業(ye)(ye)(ye)面(mian)臨(lin)的(de)個(ge)核心(xin)問題,而電(dian)費在(zai)塑(su)膠行業(ye)(ye)(ye)生(sheng)(sheng)產(chan)成本中(zhong)占有很大比例,塑(su)料企(qi)業(ye)(ye)(ye)對(dui)于節省(sheng)電(dian)費,降低生(sheng)(sheng)產(chan)成本自然非常關(guan)心(xin)。采用電(dian)磁加熱(re)(re)方式對(dui)于塑(su)料機(ji)械來(lai)說,可(ke)以有明顯(xian)的(de)節電(dian)效果,而且少可(ke)達到(dao)30%,有些原來(lai)熱(re)(re)效率(lv)不(bu)高的(de)機(ji)械更(geng)是(shi)可(ke)達到(dao)80%,也正是(shi)鑒于這點,引起范圍(wei)塑(su)料企(qi)業(ye)(ye)(ye)和行業(ye)(ye)(ye)人士的(de)關(guan)注。
電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)加(jia)熱器(qi)是(shi)(shi)種(zhong)怎(zen)樣的裝置(zhi):電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)加(jia)熱器(qi)是(shi)(shi)種(zhong)利用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)感應(ying)原理將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)轉換為(wei)熱能(neng)的裝置(zhi)。在電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)加(jia)熱器(qi)內(nei)部,由整流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)將(jiang)50/60Hz的交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)變成直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya),再(zai)經過控制電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)將(jiang)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)轉換成頻率(lv)為(wei)15-20KHz的高(gao)(gao)頻電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya),高(gao)(gao)速(su)變化的電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)流(liu)過線圈會產(chan)生(sheng)高(gao)(gao)速(su)變化的磁(ci)場(chang),當磁(ci)場(chang)內(nei)的磁(ci)力線通過金屬器(qi)皿(min)(導磁(ci)又導電(dian)(dian)(dian)(dian)(dian)(dian)材料)底部金屬體內(nei)產(chan)生(sheng)無數的小渦(wo)流(liu),使器(qi)皿(min)本身(shen)自行高(gao)(gao)速(su)發熱,然后再(zai)加(jia)熱器(qi)皿(min)內(nei)的東(dong)西。而電(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)加(jia)熱本身(shen)對器(qi)皿(min)和器(qi)皿(min)內(nei)的物品(pin)的物理性質和化學(xue)性質不產(chan)生(sheng)任何改變。
電(dian)磁加熱器的六大使(shi)用技巧:
1、在使用過程中,不要輕易拆(chai)除電磁加熱器(qi)的(de)接地導(dao)線,因為接地措施(shi)是防止觸電的(de)后道保護措施(shi)。
2、要定期(qi)清理散熱器(qi),保證電磁加熱器(qi)通風(feng)良好。
3、在(zai)使用(yong)電磁加熱器時,應(ying)先(xian)按(an)說(shuo)明書繞好線圈并(bing)檢查無誤(wu)后再(zai)接通電源。
4、在保養清洗電(dian)磁加(jia)熱器(qi)(qi)前切斷(duan)電(dian)磁加(jia)熱器(qi)(qi)的電(dian)源(yuan)。清潔電(dian)磁感應加(jia)熱器(qi)(qi)的外殼時,應用干(gan)凈(jing)的抹布進行擦(ca)拭,嚴禁用噴射水流沖洗外殼及(ji)電(dian)器(qi)(qi)箱(xiang)部分。
5、不要將電(dian)磁加熱器安裝(zhuang)在(zai)潮濕(shi)的環境中,防(fang)止(zhi)水蒸汽進(jin)入電(dian)箱后,易在(zai)緣介質表面凝結,降低其緣性能,造(zao)成漏(lou)電(dian)事故。
6、要經(jing)常檢查電磁加熱器的進風口(kou)及散(san)熱風扇,防止(zhi)進風口(kou)處堵塞或散(san)熱風扇卡死(si),避免因過熱停機(ji)保護。
電(dian)(dian)磁加(jia)熱(re)(re)(re)(re)和傳統電(dian)(dian)阻加(jia)熱(re)(re)(re)(re)對比:傳統電(dian)(dian)阻加(jia)熱(re)(re)(re)(re)熱(re)(re)(re)(re)損失大(da)(da)(da)(da):現有(you)企(qi)(qi)業(ye)(ye)專用(yong)(yong)的(de)(de)(de)(de)加(jia)熱(re)(re)(re)(re)方式,是由(you)(you)電(dian)(dian)阻絲繞(rao)制,圈(quan)的(de)(de)(de)(de)內(nei)外雙面發(fa)熱(re)(re)(re)(re),其(qi)(qi)內(nei)面(緊貼料筒部分(fen))的(de)(de)(de)(de)熱(re)(re)(re)(re)傳導到(dao)料筒上,而(er)外面的(de)(de)(de)(de)熱(re)(re)(re)(re)量(liang)(liang)大(da)(da)(da)(da)部分(fen)散(san)失到(dao)空(kong)氣中,造成電(dian)(dian)能的(de)(de)(de)(de)直(zhi)接損失、浪(lang)費。環境溫(wen)(wen)度(du)(du)上升: 由(you)(you)于熱(re)(re)(re)(re)量(liang)(liang)大(da)(da)(da)(da)量(liang)(liang)散(san)失,周圍(wei)環境溫(wen)(wen)度(du)(du)升高,尤其(qi)(qi)是夏天對生(sheng)產環境影響(xiang)很大(da)(da)(da)(da),現場工作溫(wen)(wen)度(du)(du)有(you)的(de)(de)(de)(de)已經超(chao)過了(le)45度(du)(du),有(you)些(xie)企(qi)(qi)業(ye)(ye)不得不采(cai)用(yong)(yong)空(kong)調(diao)降低(di)溫(wen)(wen)度(du)(du),這(zhe)又造成能源的(de)(de)(de)(de)二次浪(lang)費。使用(yong)(yong)壽(shou)命(ming)短(duan)、維修量(liang)(liang)大(da)(da)(da)(da): 電(dian)(dian)熱(re)(re)(re)(re)管由(you)(you)于采(cai)用(yong)(yong)電(dian)(dian)阻絲發(fa)熱(re)(re)(re)(re),其(qi)(qi)加(jia)熱(re)(re)(re)(re)溫(wen)(wen)度(du)(du)高達(da)300度(du)(du)左右,熱(re)(re)(re)(re)滯后較(jiao)大(da)(da)(da)(da),不易(yi)精確(que)控溫(wen)(wen),電(dian)(dian)阻絲容易(yi)因(yin)高溫(wen)(wen)老(lao)化而(er)燒斷。常用(yong)(yong)電(dian)(dian)熱(re)(re)(re)(re)圈(quan)使用(yong)(yong)壽(shou)命(ming)約半(ban)年,因(yin)此(ci),維修的(de)(de)(de)(de)工作量(liang)(liang)相對較(jiao)大(da)(da)(da)(da)。
