使用造粒機電磁加熱(re)器(qi)時要知道(dao)的常識:
1、我們要把造粒機電(dian)磁加熱器安置在個牢固的平(ping)臺(tai)上或掛在設備上,其附近不宜溫度過高,以防止散(san)熱不好(hao)導致(zhi)過熱保護。
2、不要將(jiang)控制器(qi)安裝在潮(chao)濕的環境中(zhong),防(fang)止(zhi)水蒸汽進入電箱后,易(yi)在緣(yuan)介質表面凝結,降低其緣(yuan)性能,造成漏電事故。
3、外部電(dian)(dian)源(yuan)在接入(ru)電(dian)(dian)磁加熱器(qi)前,應(ying)安(an)裝(zhuang)獨立的電(dian)(dian)源(yuan)空氣開關(guan)保(bao)護裝(zhuang)置。并(bing)將金屬外殼(ke)要可靠接地(di)。在使用過程中(zhong),不要輕易(yi)拆除其接地(di)導線,因(yin)為接地(di)措施(shi)是防(fang)止觸電(dian)(dian)的后道保(bao)護措施(shi)。
4、要(yao)定期清(qing)理散熱器,保證產(chan)品(pin)通風(feng)良好。要(yao)經常檢查(cha)產(chan)品(pin)的進風(feng)口(kou)及散熱風(feng)扇(shan),防止(zhi)進風(feng)口(kou)處堵(du)塞或(huo)散熱風(feng)扇(shan)卡死,避免因過(guo)熱停(ting)機保護。
下電磁加熱器耗電與什么有關:
1、電(dian)磁加熱(re)器在工作(zuo)中會直加熱(re)到(dao)設(she)(she)置(zhi)的溫度(du)(du),當溫度(du)(du)沒達到(dao)設(she)(she)置(zhi)的溫度(du)(du)時,電(dian)磁加熱(re)器就(jiu)會直加熱(re),當達到(dao)了預設(she)(she)的溫度(du)(du)以后電(dian)磁加熱(re)器就(jiu)停止加熱(re)了,也就(jiu)不(bu)再耗電(dian)了。
2、電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)器(qi)每個小時的(de)耗電(dian)(dian)量(liang)多少與電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)器(qi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)的(de)時間長短有關。電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)器(qi)剛工(gong)作是(shi)(shi)滿功率,加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)溫(wen)度到溫(wen)度以(yi)后(hou)會停止(zhi)然(ran)后(hou)再加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)。總(zong)體上來(lai)(lai)說,電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)器(qi)耗電(dian)(dian)量(liang)是(shi)(shi)很(hen)小的(de),因(yin)(yin)為電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)器(qi)不是(shi)(shi)直(zhi)(zhi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)工(gong)作的(de),而是(shi)(shi)有間隙的(de)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)的(de),達到溫(wen)度后(hou)就停止(zhi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re),之后(hou)就開始保溫(wen)工(gong)作,直(zhi)(zhi)到溫(wen)度沒達到預設的(de)溫(wen)度后(hou)再加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)下(xia),整(zheng)體上來(lai)(lai)講(jiang),電(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)器(qi)并不是(shi)(shi)直(zhi)(zhi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)耗電(dian)(dian)的(de),這也(ye)是(shi)(shi)它比較省電(dian)(dian)的(de)個原(yuan)因(yin)(yin)。
3、料筒上(shang)還(huan)包(bao)有層保溫棉也(ye)能起到保溫和隔熱的(de)效(xiao)果,那(nei)么(me)熱量(liang)(liang)就不(bu)會損失掉(diao)了,那(nei)么(me)能夠持續恒溫加熱的(de)時間就越長了。耗(hao)電量(liang)(liang)也(ye)就越小了。
電磁加熱器經常燒壞的幾個原因:
1、與工(gong)(gong)作環境有關:正常(chang)來說電磁加(jia)(jia)熱控(kong)(kong)制(zhi)器工(gong)(gong)作環境般灰塵(chen)(chen)較(jiao)多,灰塵(chen)(chen)多了之后,對電磁加(jia)(jia)熱控(kong)(kong)制(zhi)主(zhu)(zhu)板(ban)就(jiu)(jiu)非常(chang)不(bu)利。這就(jiu)(jiu)需要我(wo)們要定期清理電磁加(jia)(jia)熱器上灰塵(chen)(chen)。其次(ci)就(jiu)(jiu)是室內通(tong)風(feng)要做好,避(bi)免風(feng)扇被卡住而起不(bu)到(dao)主(zhu)(zhu)板(ban)散熱效(xiao)果從(cong)而使得元(yuan)器件過熱而燒壞。
2、與工(gong)作(zuo)時(shi)長有(you)關(guan):般像家(jia)用的(de)電磁(ci)爐每天真(zhen)正工(gong)作(zuo)時(shi)間(jian)(jian)只有(you)幾(ji)個(ge)小(xiao)時(shi),而諸如塑料機(ji)之(zhi)類的(de)行業(ye)每天天的(de)工(gong)作(zuo)時(shi)間(jian)(jian)平均超過(guo)10小(xiao)時(shi),許多廠家(jia)機(ji)器(qi)(qi)(qi)的(de)運作(zuo)時(shi)間(jian)(jian)甚至更長,因此,我們(men)企業(ye)在(zai)選購時(shi)定(ding)要(yao)看準電磁(ci)加熱控(kong)制器(qi)(qi)(qi)的(de)質量(liang),購買高質量(liang)的(de)電磁(ci)加熱控(kong)制器(qi)(qi)(qi),或者(zhe)合理安排機(ji)器(qi)(qi)(qi)運作(zuo)時(shi)間(jian)(jian)。
3、與電(dian)磁加熱(re)(re)(re)線(xian)圈有關:電(dian)磁加熱(re)(re)(re)圈著水濕了或者(zhe)破皮以及兩線(xian)之間短路等都(dou)是會造成電(dian)磁加熱(re)(re)(re)控制器燒壞。
4、出現間題不要(yao)擅(shan)自處理(li):整(zheng)流橋堆損壞導(dao)致跳閘,從(cong)而(er)導(dao)致電磁(ci)加(jia)熱控制器燒(shao)壞,因(yin)此(ci),在(zai)遇(yu)到電磁(ci)加(jia)熱設備在(zai)工(gong)作時間突然跳閘不要(yao)擅(shan)自處理(li),定要(yao)聯(lian)系我們技術人員來為您解決故(gu)障,以避(bi)免過度損壞。
電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)的使(shi)(shi)用注意事項。使(shi)(shi)用環境(jing)溫度不(bu)高于(yu)60℃,且干燥、通風(feng)。請(qing)(qing)遠(yuan)離易燃易爆(bao)物品(pin)。請(qing)(qing)勿使(shi)(shi)水及(ji)(ji)其他液體進入(ru)(ru)本(ben)(ben)機(ji)器(qi)。請(qing)(qing)勿使(shi)(shi)導電(dian)(dian)體或(huo)金屬屑進入(ru)(ru)本(ben)(ben)機(ji)器(qi),及(ji)(ji)加(jia)熱(re)體上電(dian)(dian)磁(ci)(ci)線圈。請(qing)(qing)勿在電(dian)(dian)路漏電(dian)(dian)情況(kuang)下使(shi)(shi)用本(ben)(ben)機(ji)器(qi)。請(qing)(qing)勿將本(ben)(ben)機(ji)器(qi)平放,豎立(li),以有利于(yu)散(san)熱(re)。請(qing)(qing)勿在電(dian)(dian)磁(ci)(ci)線圈周圍放置任何鐵磁(ci)(ci)質材料。電(dian)(dian)源輸入(ru)(ru)、高頻輸出嚴(yan)禁(jin)使(shi)(shi)用鋁質接線鼻。在生產停止,不(bu)需(xu)要加(jia)熱(re)時,嚴(yan)禁(jin)立(li)即切斷電(dian)(dian)源;需(xu)要等散(san)熱(re)風(feng)扇停止轉動后,再切斷電(dian)(dian)源。請(qing)(qing)及(ji)(ji)時清理灰塵,保證其干凈(jing)、整潔。新安裝機(ji)器(qi),調試前測試電(dian)(dian)感量(liang),待電(dian)(dian)感量(liang)符合(he)要求(qiu)后再試機(ji)。非專業人(ren)士請(qing)(qing)勿調動本(ben)(ben)機(ji)器(qi),如有問題(ti)請(qing)(qing)和經銷商或(huo)廠家聯系。接入(ru)(ru)電(dian)(dian)源電(dian)(dian)壓應符合(he)本(ben)(ben)機(ji)器(qi)電(dian)(dian)氣規格中(zhong)要求(qiu)的參(can)數。
冬季如(ru)何保養電磁加熱器中的保溫箱:
1、電(dian)(dian)熱(re)(re)(re)管伴熱(re)(re)(re)保溫(wen)(wen)箱(xiang),由箱(xiang)體(ti)、加熱(re)(re)(re)器(qi)、儀表(biao)托(tuo)架等三(san)大部分(fen)組(zu)成,其結構形式與保護(hu)箱(xiang)相(xiang)同,所(suo)不同的是箱(xiang)內裝有(you)電(dian)(dian)器(qi)加熱(re)(re)(re)裝置,起(qi)熱(re)(re)(re)裝置是由電(dian)(dian)熱(re)(re)(re)管,溫(wen)(wen)度(du)(du)(du)控(kong)制器(qi)組(zu)成,箱(xiang)體(ti)側面裝有(you)插座,當(dang)接通電(dian)(dian)源(yuan)后,箱(xiang)內加熱(re)(re)(re)到所(suo)需溫(wen)(wen)度(du)(du)(du)時,再由溫(wen)(wen)度(du)(du)(du)控(kong)制器(qi)接通電(dian)(dian)源(yuan)繼續(xu)升溫(wen)(wen)。通過反(fan)復工作使箱(xiang)內溫(wen)(wen)度(du)(du)(du)能(neng)保持(chi)在(zai)定(ding)范(fan)圍內。其恒溫(wen)(wen)加熱(re)(re)(re)器(qi)主要參數:額定(ding)電(dian)(dian)壓380V,三(san)相(xiang)四線制、額定(ding)功率50HZ、控(kong)制溫(wen)(wen)度(du)(du)(du)可由用戶自(zi)定(ding)、恒溫(wen)(wen)加熱(re)(re)(re)器(qi)也可做成防爆型。
2、蒸(zheng)氣(qi)管(guan)伴熱保溫箱(xiang),箱(xiang)體上下(xia)采用焊(han)接(jie)式(shi)穿板接(jie)頭與伴熱管(guan)焊(han)接(jie)而成,伴熱管(guan)安裝(zhuang)在(zai)箱(xiang)內為上進(jin)下(xia)出,通過蒸(zheng)氣(qi)在(zai)管(guan)腔內的循(xun)環而達(da)到(dao)加熱目的。
3、為(wei)關鍵加(jia)熱器再加(jia)層保溫棉,在保溫箱門口和進出(chu)管(guan)線口加(jia)膠密封,可(ke)達到電(dian)磁加(jia)熱器系統更保溫防凍效果。
如(ru)何(he)選擇電磁加熱器保溫材料?
1、根據材料的耐溫(wen)等,選擇耐溫(wen)比發熱(re)體表面的加熱(re)溫(wen)度高(gao)至少300度的保溫(wen)材料。
2、根據電(dian)磁加熱控制器線圈布置(zhi)的(de)面積(ji)以及線圈與發熱體的(de)距離,選擇合適導(dao)熱系數的(de)保溫(wen)材(cai)料。
3、根(gen)據線圈成(cheng)型要求,選(xuan)擇(ze)不同致(zhi)密(mi)性和硬度的(de)保溫材料。
4、根據現場的施工(gong)條件,選擇(ze)適合的保溫(wen)材料。
5、重要的條原則,就是(shi)要保(bao)證經過(guo)上(shang)述選(xuan)擇后,保(bao)溫棉表面的溫度在工作(zuo)過(guo)程中(zhong),盡可能低。高溫場合(he)至少要保(bao)持(chi)在100度以下。
電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)能(neng)省電(dian)(dian)的(de)(de)(de)原因(yin)及效(xiao)果:電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)器(qi)的(de)(de)(de)原理是(shi)(shi)電(dian)(dian)磁(ci)(ci)感(gan)(gan)應(ying)加(jia)熱(re)(re)的(de)(de)(de)原理,它采用(yong)(yong)內部加(jia)熱(re)(re)的(de)(de)(de)方法,即讓材(cai)(cai)料自身發熱(re)(re),而不是(shi)(shi)傳遞熱(re)(re)量,它是(shi)(shi)通過(guo)電(dian)(dian)、磁(ci)(ci)和(he)熱(re)(re)之間的(de)(de)(de)能(neng)量轉(zhuan)換(huan)來達到加(jia)熱(re)(re)材(cai)(cai)料的(de)(de)(de)目(mu)的(de)(de)(de)。此外,還有包裝20Mm厚的(de)(de)(de)保溫(wen)棉外容器(qi)的(de)(de)(de)材(cai)(cai)料。可(ke)以說,電(dian)(dian)磁(ci)(ci)感(gan)(gan)應(ying)加(jia)熱(re)(re)過(guo)程中(zhong)存在的(de)(de)(de)熱(re)(re)量損失(shi)很低(di),熱(re)(re)能(neng)利(li)(li)用(yong)(yong)率高達98%。相反,電(dian)(dian)磁(ci)(ci)感(gan)(gan)應(ying)加(jia)熱(re)(re)的(de)(de)(de)節電(dian)(dian)效(xiao)果是(shi)(shi)相當可(ke)觀(guan)的(de)(de)(de),用(yong)(yong)電(dian)(dian)磁(ci)(ci)輻射熱(re)(re)利(li)(li)用(yong)(yong)率的(de)(de)(de)高值(zhi)和(he)低(di)值(zhi)減(jian)去電(dian)(dian)阻(zu)加(jia)熱(re)(re)的(de)(de)(de)小值(zhi)和(he)大值(zhi),就可(ke)以從電(dian)(dian)磁(ci)(ci)加(jia)熱(re)(re)中(zhong)獲得種(zhong)節約電(dian)(dian)量。
此外,挑選(xuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)時,還要考(kao)(kao)慮其(qi)(qi)線(xian)(xian)(xian)(xian)徑,材(cai)(cai)質,耐(nai)(nai)(nai)溫耐(nai)(nai)(nai)壓性(xing)能(neng)等。這些(xie)也都是(shi)(shi)(shi)(shi)由其(qi)(qi)使用(yong)(yong)(yong)條件(jian)決定(ding)的(de)(de)(de)(de)。在實(shi)際選(xuan)配(pei)過程(cheng)中,先(xian)要根據(ju)加熱(re)需(xu)求(qiu)確定(ding)所(suo)需(xu)設(she)備功(gong)率(lv),然(ran)后就(jiu)(jiu)可以(yi)知(zhi)道其(qi)(qi)輸出(chu)電(dian)(dian)流值,進而確定(ding)線(xian)(xian)(xian)(xian)徑、材(cai)(cai)質,然(ran)后視現場(chang)的(de)(de)(de)(de)溫度情(qing)(qing)況(kuang),散(san)熱(re)情(qing)(qing)況(kuang)等考(kao)(kao)慮其(qi)(qi)耐(nai)(nai)(nai)溫性(xing)能(neng)。如(ru)果(guo)挑選(xuan)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)時沒有(you)(you)考(kao)(kao)慮到(dao)這些(xie)因(yin)素(su),就(jiu)(jiu)很容易出(chu)現設(she)備故障,例(li)如(ru)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)被燒(shao)壞,加熱(re)效率(lv)低(di)下,線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)(bu)耐(nai)(nai)(nai)用(yong)(yong)(yong)等問題(ti)。輕則影響生產,重則造成人身(shen)事(shi)故。二線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)(rao)制(zhi):表面看(kan)來(lai),線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)(rao)制(zhi)這工(gong)作似乎是(shi)(shi)(shi)(shi)沒技術含量(liang)的(de)(de)(de)(de),不(bu)(bu)(bu)(bu)就(jiu)(jiu)是(shi)(shi)(shi)(shi)把線(xian)(xian)(xian)(xian)材(cai)(cai)繞(rao)(rao)(rao)下組成個(ge)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)嘛,這誰不(bu)(bu)(bu)(bu)會?但實(shi)際上并沒有(you)(you)那么簡(jian)單(dan),線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)(de)(de)繞(rao)(rao)(rao)制(zhi)需(xu)要考(kao)(kao)慮到(dao)疊加、干擾、散(san)熱(re)、距(ju)離、感(gan)量(liang)匹配(pei)等因(yin)素(su)。不(bu)(bu)(bu)(bu)同功(gong)率(lv)的(de)(de)(de)(de)電(dian)(dian)磁(ci)加熱(re)器其(qi)(qi)所(suo)需(xu)要的(de)(de)(de)(de)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)感(gan)量(liang)是(shi)(shi)(shi)(shi)不(bu)(bu)(bu)(bu)樣的(de)(de)(de)(de),只有(you)(you)實(shi)際電(dian)(dian)感(gan)量(liang)和理(li)(li)論(lun)值直,才(cai)能(neng)保證電(dian)(dian)磁(ci)加熱(re)器的(de)(de)(de)(de)功(gong)率(lv)大化。例(li)如(ru),臺(tai)(tai)30KW的(de)(de)(de)(de)電(dian)(dian)磁(ci)加熱(re)器,其(qi)(qi)理(li)(li)論(lun)電(dian)(dian)感(gan)量(liang)是(shi)(shi)(shi)(shi)240μH,線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)(rao)制(zhi)時,只有(you)(you)實(shi)際感(gan)量(liang)為240μH,其(qi)(qi)功(gong)率(lv)才(cai)有(you)(you)可能(neng)完全達(da)到(dao)。如(ru)果(guo)實(shi)際感(gan)量(liang)是(shi)(shi)(shi)(shi)100μH、150μH、300μH、400μH,那其(qi)(qi)這臺(tai)(tai)設(she)備的(de)(de)(de)(de)實(shi)際使用(yong)(yong)(yong)功(gong)率(lv)可能(neng)就(jiu)(jiu)只有(you)(you)20KW,15KW,甚至(zhi)根本(ben)啟動不(bu)(bu)(bu)(bu)了。三適用(yong)(yong)(yong)見場(chang):電(dian)(dian)磁(ci)加熱(re)器的(de)(de)(de)(de)廣(guang)泛應用(yong)(yong)(yong)性(xing)決定(ding)了其(qi)(qi)現場(chang)使用(yong)(yong)(yong)情(qing)(qing)況(kuang)的(de)(de)(de)(de)復雜。在電(dian)(dian)磁(ci)加熱(re)器眾多的(de)(de)(de)(de)使用(yong)(yong)(yong)域中,食品、塑料、化工(gong)、印刷、供暖、垃圾處(chu)理(li)(li),每個(ge)行業的(de)(de)(de)(de)應用(yong)(yong)(yong)場(chang)景都不(bu)(bu)(bu)(bu)同,就(jiu)(jiu)是(shi)(shi)(shi)(shi)同個(ge)行業中,每個(ge)客(ke)戶的(de)(de)(de)(de)使用(yong)(yong)(yong)現場(chang)也有(you)(you)很大的(de)(de)(de)(de)差(cha)別。所(suo)以(yi),電(dian)(dian)磁(ci)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)(bu)具有(you)(you)普遍適用(yong)(yong)(yong)性(xing),是(shi)(shi)(shi)(shi)種(zhong)不(bu)(bu)(bu)(bu)同使用(yong)(yong)(yong)場(chang)景有(you)(you)不(bu)(bu)(bu)(bu)同繞(rao)(rao)(rao)法的(de)(de)(de)(de)非標配(pei)件(jian)。
