電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)器可以(yi)多溫區控(kong)制(zhi)嗎(ma)?橡(xiang)膠機(ji)多溫區加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)早些年常用(yong)(yong)的(de)(de)莫過(guo)(guo)于電(dian)(dian)(dian)(dian)(dian)阻加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re),這(zhe)種加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)方(fang)式熱(re)(re)效率(lv)不(bu)高(gao),耗電(dian)(dian)(dian)(dian)(dian)量比(bi)較大。目前理想的(de)(de)橡(xiang)膠機(ji)多溫區加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)建議(yi)采用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)器加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)設備,通(tong)過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)圈產(chan)生渦流使(shi)管(guan)(guan)道自身發熱(re)(re)。管(guan)(guan)道加(jia)(jia)(jia)(jia)(jia)(jia)包層2.5公(gong)分的(de)(de)保溫棉,這(zhe)樣(yang)熱(re)(re)量不(bu)容易外散到空氣。電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)圈的(de)(de)外部(bu)溫度只有(you)幾十(shi)度,工作室溫也會由(you)此而(er)減(jian)低。晶星電(dian)(dian)(dian)(dian)(dian)子科技有(you)限公(gong)司(si)據用(yong)(yong)戶親(qin)自測試,橡(xiang)膠機(ji)多溫區改(gai)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)器相(xiang)比(bi)電(dian)(dian)(dian)(dian)(dian)熱(re)(re)圈至少(shao)省(sheng)電(dian)(dian)(dian)(dian)(dian)在30%以(yi)上,非(fei)常實用(yong)(yong)。橡(xiang)膠機(ji)多溫區加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)般為多條(tiao)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)管(guan)(guan)道,條(tiao)管(guan)(guan)道使(shi)用(yong)(yong)2組或者多組電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)器。實際要根據橡(xiang)膠機(ji)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)管(guan)(guan)道尺寸而(er)定(ding)。電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)板使(shi)用(yong)(yong)功率(lv)般為15kw-20kw電(dian)(dian)(dian)(dian)(dian)磁加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)器。
電磁(ci)加熱器的(de)六大(da)使(shi)用(yong)技巧:
1、在使用過程中,不要輕(qing)易拆除電磁(ci)加熱器的(de)接地(di)導(dao)線,因為接地(di)措(cuo)施是防止觸電的(de)后道(dao)保護措(cuo)施。
2、要定期清理散熱器,保(bao)證電磁加熱器通風良(liang)好(hao)。
3、在使用電(dian)磁加熱器時,應先(xian)按說明書繞(rao)好(hao)線圈并檢查無誤后再接通電(dian)源。
4、在保養清洗(xi)電(dian)(dian)磁(ci)加(jia)(jia)熱(re)器前切斷電(dian)(dian)磁(ci)加(jia)(jia)熱(re)器的電(dian)(dian)源。清潔電(dian)(dian)磁(ci)感應加(jia)(jia)熱(re)器的外(wai)殼時,應用干凈的抹布進行擦(ca)拭,嚴禁用噴(pen)射水(shui)流(liu)沖洗(xi)外(wai)殼及電(dian)(dian)器箱部分。
5、不要將電磁加熱器(qi)安裝在潮濕的環境中,防(fang)止水蒸(zheng)汽進入(ru)電箱后,易在緣(yuan)介質表面凝結,降低其緣(yuan)性能,造成漏電事故。
6、要經常(chang)檢查電磁加熱器的進風口及散(san)熱風扇,防(fang)止進風口處堵塞或散(san)熱風扇卡死,避免因過熱停(ting)機(ji)保(bao)護。
電(dian)磁加熱(re)(re)(re)器(qi)(qi)用(yong)風冷(leng)(leng)的(de)(de)好還(huan)是(shi)(shi)水(shui)冷(leng)(leng)的(de)(de)好?現今工業(ye)(ye)域和民用(yong)設備中較廣泛的(de)(de)種(zhong)加熱(re)(re)(re)方式(shi),主(zhu)要是(shi)(shi)采用(yong)電(dian)磁加熱(re)(re)(re)技術(shu),在使用(yong)電(dian)磁加熱(re)(re)(re)器(qi)(qi)中用(yong)戶都關心的(de)(de)電(dian)磁加熱(re)(re)(re)器(qi)(qi)是(shi)(shi)水(shui)冷(leng)(leng)好還(huan)是(shi)(shi)風冷(leng)(leng)好呢?電(dian)磁加熱(re)(re)(re)器(qi)(qi)作業(ye)(ye)段時間后,控(kong)制(zhi)(zhi)(zhi)面板(ban)是(shi)(shi)會發熱(re)(re)(re)發燙的(de)(de),所以就(jiu)需(xu)要對(dui)(dui)控(kong)制(zhi)(zhi)(zhi)板(ban)進行降(jiang)溫處理(li),避免(mian)由于控(kong)制(zhi)(zhi)(zhi)板(ban)溫度過高,自(zi)身(shen)過熱(re)(re)(re)保護(hu)致使電(dian)磁加熱(re)(re)(re)器(qi)(qi)中止加熱(re)(re)(re)作業(ye)(ye)。通常對(dui)(dui)控(kong)制(zhi)(zhi)(zhi)板(ban)降(jiang)溫處理(li)方法有兩種(zhong),種(zhong)是(shi)(shi)風冷(leng)(leng)的(de)(de),另種(zhong)是(shi)(shi)水(shui)冷(leng)(leng)的(de)(de)。對(dui)(dui)于風冷(leng)(leng)和水(shui)冷(leng)(leng)的(de)(de)電(dian)磁加熱(re)(re)(re)器(qi)(qi)哪個好就(jiu)要依據場合、氣候、環境而論。
電磁(ci)(ci)加(jia)(jia)熱(re)(re)器(qi)(qi)的(de)(de)溫(wen)度(du)(du)調節(jie)不準是(shi)怎么回事(shi)? 電磁(ci)(ci)加(jia)(jia)熱(re)(re)器(qi)(qi)系統(tong)包括電磁(ci)(ci)加(jia)(jia)熱(re)(re)控(kong)制(zhi)器(qi)(qi)和電磁(ci)(ci)加(jia)(jia)熱(re)(re)圈這兩部分,每個行業(ye)中(zhong)對于(yu)(yu)溫(wen)控(kong)的(de)(de)要(yao)求(qiu)都不樣(yang)(yang),下面(mian)就(jiu)來介(jie)紹電磁(ci)(ci)加(jia)(jia)熱(re)(re)器(qi)(qi)如何達到精(jing)確(que)(que)是(shi)溫(wen)控(kong)效果?塑(su)(su)料(liao)(liao)行業(ye)中(zhong)加(jia)(jia)熱(re)(re)器(qi)(qi),重要(yao)指標(biao)就(jiu)是(shi)保證機(ji)器(qi)(qi)各溫(wen)區的(de)(de)溫(wen)度(du)(du)精(jing)確(que)(que)性(xing),各種塑(su)(su)料(liao)(liao)原(yuan)料(liao)(liao)對于(yu)(yu)溫(wen)度(du)(du)的(de)(de)敏感性(xing)雖然不樣(yang)(yang),但在生(sheng)產(chan)過程中(zhong)對于(yu)(yu)溫(wen)度(du)(du)精(jing)確(que)(que)性(xing)的(de)(de)要(yao)求(qiu)都比較高,很(hen)多塑(su)(su)料(liao)(liao)產(chan)品(pin)要(yao)求(qiu)溫(wen)度(du)(du)不能(neng)超過±5℃,因此,很(hen)多種類的(de)(de)塑(su)(su)料(liao)(liao)機(ji)有采用風冷或水冷進(jin)行降(jiang)溫(wen)控(kong)制(zhi),否則,加(jia)(jia)工出來的(de)(de)東西可(ke)能(neng)不是(shi)廢品(pin)就(jiu)是(shi)次品(pin)。電磁(ci)(ci)加(jia)(jia)熱(re)(re)器(qi)(qi)利(li)用電磁(ci)(ci)加(jia)(jia)熱(re)(re)控(kong)制(zhi)板,再配以必要(yao)的(de)(de)風冷、水冷裝(zhuang)置,溫(wen)度(du)(du)控(kong)制(zhi)可(ke)以精(jing)確(que)(que)到±1℃。當然同時也(ye)要(yao)對塑(su)(su)料(liao)(liao)機(ji)性(xing)能(neng)及(ji)塑(su)(su)料(liao)(liao)原(yuan)料(liao)(liao)有全面(mian)了解及(ji)進(jin)行必要(yao)合(he)理配置。這樣(yang)(yang)可(ke)以降(jiang)低企業(ye)損耗、提高企業(ye)效益。產(chan)品(pin)性(xing)能(neng)穩定、節(jie)能(neng)、環(huan)保,產(chan)出的(de)(de)顆粒品(pin)質(zhi)好。
電磁感應(ying)加熱(re)器(qi)不加熱(re)原(yuan)因主要有以下三(san)點(dian):
1、線路故障,沒(mei)電供及。
2、元件損壞,查(cha)找更換。
3、調整不當,重新調整適當數據。
電(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)能(neng)省電(dian)(dian)的(de)(de)(de)原(yuan)(yuan)因及效(xiao)(xiao)果:電(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)器的(de)(de)(de)原(yuan)(yuan)理是電(dian)(dian)磁(ci)(ci)感應(ying)加(jia)(jia)熱(re)(re)(re)的(de)(de)(de)原(yuan)(yuan)理,它(ta)采用內部加(jia)(jia)熱(re)(re)(re)的(de)(de)(de)方法,即讓材料(liao)自身(shen)發熱(re)(re)(re),而不是傳遞熱(re)(re)(re)量(liang),它(ta)是通過電(dian)(dian)、磁(ci)(ci)和熱(re)(re)(re)之(zhi)間的(de)(de)(de)能(neng)量(liang)轉換來達到加(jia)(jia)熱(re)(re)(re)材料(liao)的(de)(de)(de)目的(de)(de)(de)。此外,還(huan)有包(bao)裝(zhuang)20Mm厚的(de)(de)(de)保(bao)溫棉外容(rong)器的(de)(de)(de)材料(liao)。可(ke)以(yi)說(shuo),電(dian)(dian)磁(ci)(ci)感應(ying)加(jia)(jia)熱(re)(re)(re)過程(cheng)中(zhong)(zhong)存在的(de)(de)(de)熱(re)(re)(re)量(liang)損(sun)失很低(di),熱(re)(re)(re)能(neng)利用率高(gao)達98%。相反,電(dian)(dian)磁(ci)(ci)感應(ying)加(jia)(jia)熱(re)(re)(re)的(de)(de)(de)節(jie)電(dian)(dian)效(xiao)(xiao)果是相當(dang)可(ke)觀的(de)(de)(de),用電(dian)(dian)磁(ci)(ci)輻射熱(re)(re)(re)利用率的(de)(de)(de)高(gao)值和低(di)值減(jian)去電(dian)(dian)阻加(jia)(jia)熱(re)(re)(re)的(de)(de)(de)小(xiao)值和大值,就可(ke)以(yi)從電(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)中(zhong)(zhong)獲得種節(jie)約電(dian)(dian)量(liang)。
電(dian)磁加(jia)(jia)熱器(qi)裝置后(hou)溫(wen)度(du)(du)不(bu)(bu)達(da)(da)標處理方(fang)法,當造粒(li)機類(lei)似(si)大(da)功率時(shi),安(an)裝電(dian)磁加(jia)(jia)熱器(qi)后(hou),溫(wen)度(du)(du)總(zong)達(da)(da)不(bu)(bu)到。電(dian)磁加(jia)(jia)熱器(qi)也直工作,電(dian)流也正(zheng)常,但溫(wen)度(du)(du)總(zong)上(shang)不(bu)(bu)去。般情況是(shi)(shi)功率不(bu)(bu)夠大(da)。可以(yi)(yi)加(jia)(jia)大(da)實(shi)(shi)際功率來(lai)實(shi)(shi)現。要是(shi)(shi)確定實(shi)(shi)際功率不(bu)(bu)小了(le),這是(shi)(shi)由炮(pao)筒的材(cai)料(liao)引起的,不(bu)(bu)同材(cai)質的在不(bu)(bu)同的工作頻(pin)率時(shi)吸收熱量(liang)也不(bu)(bu)同。應該嘗(chang)試(shi)增加(jia)(jia)諧振電(dian)容容量(liang),讓(rang)Q值增加(jia)(jia),提高(gao)線(xian)圈高(gao)頻(pin)電(dian)流。可以(yi)(yi)使炮(pao)筒內(nei)外溫(wen)度(du)(du)均勻來(lai)達(da)(da)到提高(gao)炮(pao)筒的溫(wen)度(du)(du)。條(tiao)件允話(hua)的話(hua),可以(yi)(yi)換掉(diao)炮(pao)筒試(shi)試(shi)。
電(dian)磁加熱器的(de)全(quan)橋和半橋的(de)投資(zi)成(cheng)本與產(chan)品配(pei)置(zhi)的(de)異同(tong):
、相(xiang)同:在普通用途(tu)上,均(jun)可全系列(lie)配置各種產品。
二、投資成(cheng)本上(shang)不同:
1、全(quan)橋(qiao):因其設計配置較高,無可避免生(sheng)產成(cheng)本較高。
2、半橋:因其設(she)計配置(zhi)較(jiao)低,生(sheng)產(chan)成本(ben)較(jiao)低。
三、產品配置上:
1、全橋:成本合理和負載耐(nai)用上(shang),配置30KW以(yi)上(shang)產品較(jiao)宜(yi)。
2、半橋:成本(ben)合理上,配置30KW以(yi)下產品較(jiao)宜。
