電磁(ci)加熱調節溫度控制方(fang)式:
1、臺電磁加(jia)熱器控制段溫度。
2、多臺(tai)電磁加熱器用個溫控(kong)器開關(guan)控(kong)制。
3、繼電器控制。
4、如果(guo)加熱水的話還可以(yi)用(yong)流速控制溫度。
5、分時間控制。
電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)器,是(shi)現(xian)今工(gong)業域和(he)民用設備中(zhong)廣泛的(de)(de)種(zhong)(zhong)加(jia)(jia)(jia)熱(re)(re)(re)方(fang)式,采(cai)用電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)熱(re)(re)(re)技術(shu)(shu),電(dian)(dian)(dian)磁(ci)感應加(jia)(jia)(jia)熱(re)(re)(re)技術(shu)(shu)簡稱為 IH(Induction Heating)技術(shu)(shu),是(shi)在(zai)法拉第感應定(ding)律的(de)(de)基礎上(shang)發展(zhan)起來的(de)(de),是(shi)法拉第感應定(ding)律的(de)(de)種(zhong)(zhong)應用形(xing)式。其本質(zhi)就是(shi)利(li)用電(dian)(dian)(dian)磁(ci)感應在(zai)柱(zhu)體內(nei)產生渦流來給加(jia)(jia)(jia)熱(re)(re)(re)工(gong)件的(de)(de)電(dian)(dian)(dian)加(jia)(jia)(jia)熱(re)(re)(re),它是(shi)把電(dian)(dian)(dian)能轉(zhuan)換(huan)為電(dian)(dian)(dian)磁(ci)能,再由(you)電(dian)(dian)(dian)磁(ci)能轉(zhuan)換(huan)為電(dian)(dian)(dian)能,電(dian)(dian)(dian)能在(zai)金屬內(nei)部轉(zhuan)變(bian)為熱(re)(re)(re)能,達到加(jia)(jia)(jia)熱(re)(re)(re)金屬的(de)(de)目的(de)(de),從而杜了明(ming)火(huo)在(zai)加(jia)(jia)(jia)熱(re)(re)(re)過程中(zhong)的(de)(de)危(wei)害和(he)干擾,是(shi)種(zhong)(zhong)環保,提倡的(de)(de)加(jia)(jia)(jia)熱(re)(re)(re)方(fang)案。
電(dian)(dian)(dian)(dian)阻線材(cai)(cai)加(jia)(jia)熱(re)(re)(re)(re)過程(cheng)中電(dian)(dian)(dian)(dian)能浪(lang)費的原因:傳統采暖行業普遍采用(yong)電(dian)(dian)(dian)(dian)阻導線和石英(ying)加(jia)(jia)熱(re)(re)(re)(re)方式(shi),這種傳統加(jia)(jia)熱(re)(re)(re)(re)方式(shi)熱(re)(re)(re)(re)效率(lv)低(di)。電(dian)(dian)(dian)(dian)阻絲(si)和石英(ying)主要通過電(dian)(dian)(dian)(dian)加(jia)(jia)熱(re)(re)(re)(re),然后熱(re)(re)(re)(re)量轉(zhuan)移到(dao)料(liao)桶上。作為(wei)種加(jia)(jia)熱(re)(re)(re)(re)材(cai)(cai)料(liao),這種加(jia)(jia)熱(re)(re)(re)(re)效果的大(da)熱(re)(re)(re)(re)利用(yong)率(lv)僅為(wei)50%左(zuo)右(you),其余50%左(zuo)右(you)的熱(re)(re)(re)(re)量被排放到(dao)空(kong)氣中。傳統電(dian)(dian)(dian)(dian)阻線材(cai)(cai)加(jia)(jia)熱(re)(re)(re)(re)方式(shi)的電(dian)(dian)(dian)(dian)能損耗高達(da)50%。
電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)的(de)(de)溫(wen)度調節不(bu)(bu)準是(shi)怎么回事? 電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)系統包(bao)括(kuo)電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)控(kong)(kong)制(zhi)器(qi)和電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)圈(quan)這兩部分,每個行業中對(dui)于(yu)溫(wen)控(kong)(kong)的(de)(de)要(yao)(yao)求(qiu)都不(bu)(bu)樣(yang)(yang),下面(mian)就來介紹電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)如何達到精(jing)確是(shi)溫(wen)控(kong)(kong)效果(guo)?塑料(liao)(liao)行業中加(jia)熱(re)器(qi),重要(yao)(yao)指標(biao)就是(shi)保(bao)證機器(qi)各溫(wen)區的(de)(de)溫(wen)度精(jing)確性(xing),各種塑料(liao)(liao)原料(liao)(liao)對(dui)于(yu)溫(wen)度的(de)(de)敏(min)感性(xing)雖然不(bu)(bu)樣(yang)(yang),但在生產過程中對(dui)于(yu)溫(wen)度精(jing)確性(xing)的(de)(de)要(yao)(yao)求(qiu)都比較高(gao),很多(duo)(duo)塑料(liao)(liao)產品要(yao)(yao)求(qiu)溫(wen)度不(bu)(bu)能(neng)超過±5℃,因此,很多(duo)(duo)種類(lei)的(de)(de)塑料(liao)(liao)機有采用(yong)風冷(leng)或水冷(leng)進行降(jiang)溫(wen)控(kong)(kong)制(zhi),否則,加(jia)工出來的(de)(de)東(dong)西可(ke)能(neng)不(bu)(bu)是(shi)廢品就是(shi)次品。電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)利用(yong)電(dian)(dian)(dian)(dian)磁(ci)(ci)加(jia)熱(re)控(kong)(kong)制(zhi)板,再(zai)配(pei)以必(bi)要(yao)(yao)的(de)(de)風冷(leng)、水冷(leng)裝(zhuang)置,溫(wen)度控(kong)(kong)制(zhi)可(ke)以精(jing)確到±1℃。當然同時也要(yao)(yao)對(dui)塑料(liao)(liao)機性(xing)能(neng)及(ji)(ji)塑料(liao)(liao)原料(liao)(liao)有全面(mian)了解(jie)及(ji)(ji)進行必(bi)要(yao)(yao)合理配(pei)置。這樣(yang)(yang)可(ke)以降(jiang)低企(qi)業損耗、提高(gao)企(qi)業效益。產品性(xing)能(neng)穩定、節能(neng)、環保(bao),產出的(de)(de)顆粒品質好(hao)。
電(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)裝置后溫度不(bu)達(da)標處理方法,當造粒機類似大功(gong)率(lv)時(shi),安裝電(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)后,溫度總(zong)達(da)不(bu)到。電(dian)磁(ci)(ci)加(jia)(jia)(jia)熱(re)器(qi)也直工(gong)(gong)作,電(dian)流(liu)也正常,但溫度總(zong)上不(bu)去(qu)。般情況是(shi)功(gong)率(lv)不(bu)夠大。可以(yi)加(jia)(jia)(jia)大實(shi)(shi)際功(gong)率(lv)來(lai)實(shi)(shi)現。要是(shi)確(que)定實(shi)(shi)際功(gong)率(lv)不(bu)小了,這是(shi)由炮(pao)筒的(de)(de)材料(liao)引(yin)起的(de)(de),不(bu)同材質的(de)(de)在不(bu)同的(de)(de)工(gong)(gong)作頻率(lv)時(shi)吸收熱(re)量也不(bu)同。應該嘗試(shi)增加(jia)(jia)(jia)諧(xie)振電(dian)容容量,讓(rang)Q值增加(jia)(jia)(jia),提高線圈高頻電(dian)流(liu)。可以(yi)使炮(pao)筒內外(wai)溫度均勻來(lai)達(da)到提高炮(pao)筒的(de)(de)溫度。條(tiao)件允話的(de)(de)話,可以(yi)換掉炮(pao)筒試(shi)試(shi)。
下(xia)電(dian)磁(ci)加熱器耗(hao)電(dian)與什么有關:
1、電磁加(jia)(jia)熱(re)(re)器(qi)在工(gong)作中會直加(jia)(jia)熱(re)(re)到(dao)設置的(de)(de)溫(wen)(wen)度,當溫(wen)(wen)度沒達到(dao)設置的(de)(de)溫(wen)(wen)度時,電磁加(jia)(jia)熱(re)(re)器(qi)就(jiu)(jiu)會直加(jia)(jia)熱(re)(re),當達到(dao)了預設的(de)(de)溫(wen)(wen)度以后(hou)電磁加(jia)(jia)熱(re)(re)器(qi)就(jiu)(jiu)停止加(jia)(jia)熱(re)(re)了,也就(jiu)(jiu)不再耗(hao)電了。
2、電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)每個小(xiao)時的(de)耗(hao)(hao)電(dian)量(liang)多少與電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)的(de)時間長(chang)短有關。電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)剛工作是(shi)(shi)滿功率,加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)溫(wen)度(du)(du)到溫(wen)度(du)(du)以后會停止(zhi)然后再加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)。總體上(shang)來說,電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)耗(hao)(hao)電(dian)量(liang)是(shi)(shi)很(hen)小(xiao)的(de),因(yin)為電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)不是(shi)(shi)直(zhi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)工作的(de),而(er)是(shi)(shi)有間隙的(de)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)的(de),達(da)到溫(wen)度(du)(du)后就停止(zhi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re),之后就開始保(bao)溫(wen)工作,直(zhi)到溫(wen)度(du)(du)沒達(da)到預設的(de)溫(wen)度(du)(du)后再加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)下,整體上(shang)來講,電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)器(qi)(qi)并不是(shi)(shi)直(zhi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)耗(hao)(hao)電(dian)的(de),這也是(shi)(shi)它比較省(sheng)電(dian)的(de)個原因(yin)。
3、料筒(tong)上還包(bao)有層保(bao)溫(wen)棉(mian)也能(neng)起(qi)到(dao)保(bao)溫(wen)和隔熱(re)的效果(guo),那么(me)熱(re)量就(jiu)不會損失掉了(le),那么(me)能(neng)夠持續恒溫(wen)加熱(re)的時間(jian)就(jiu)越長了(le)。耗電量也就(jiu)越小(xiao)了(le)。
電磁加熱器區別:
、家用(yong)(yong)(yong)電(dian)磁(ci)爐功(gong)率相對(dui)較小,且(qie)是220V交流(liu)轉變(bian)成直流(liu),實現方法(fa)簡單,家用(yong)(yong)(yong)電(dian)磁(ci)爐功(gong)率般在2200瓦以(yi)(yi)內(nei)(實際功(gong)率1900瓦以(yi)(yi)內(nei)),家用(yong)(yong)(yong)電(dian)磁(ci)爐要求保證每天(tian)工(gong)(gong)作(zuo)2-3小時。而電(dian)磁(ci)加(jia)(jia)熱器則是應用(yong)(yong)(yong)在工(gong)(gong)業(ye)設備(bei)(bei)上,并(bing)且(qie)功(gong)率達到(dao)了60KW,選材和(he)(he)控制模式與家用(yong)(yong)(yong)電(dian)磁(ci)爐是完全(quan)不同的。電(dian)磁(ci)加(jia)(jia)熱器是屬于商用(yong)(yong)(yong)工(gong)(gong)業(ye)產品。具備(bei)(bei)家用(yong)(yong)(yong)電(dian)磁(ci)爐無法(fa)比(bi)擬的穩(wen)定性和(he)(he)耐用(yong)(yong)(yong)性。正常使用(yong)(yong)(yong),可連續工(gong)(gong)作(zuo)10年(nian)(10萬(wan)小時)以(yi)(yi)上。
二、電(dian)磁(ci)(ci)加熱(re)(re)器和家(jia)(jia)用電(dian)磁(ci)(ci)爐區別之(zhi)家(jia)(jia)用電(dian)磁(ci)(ci)爐是為了滿足居家(jia)(jia)生活而設計開發(fa)的,而電(dian)磁(ci)(ci)加熱(re)(re)器是為了解決塑料加熱(re)(re)的問題而設計開發(fa)。
電磁感應加熱器(qi)對比普(pu)通(tong)熱圈(quan)加熱方(fang)式有什(shen)么優勢?
1、耗電的95%轉化為工作熱(re)能線圈損耗≈2%,控(kong)制單元(yuan)損耗≈2%,緣隔熱(re)層(ceng)可(ke)以將98%的能量保留(liu)在料筒上(shang)。
2、只加(jia)熱料筒,而(er)螺桿保持冷卻(que)。
3、消除(chu)加(jia)熱的慣(guan)性(xing)現象,升溫(wen)降溫(wen)迅速。
4、電磁感應加熱(re)器加熱(re)無死角,整體料筒(tong)均勻加熱(re)。
5、電磁線圈保持涼爽,因此壽命超長。
