電(dian)(dian)磁(ci)(ci)加(jia)熱器(qi)的使(shi)(shi)用(yong)注意事項。使(shi)(shi)用(yong)環(huan)境溫度不高(gao)于60℃,且(qie)干(gan)燥、通風。請(qing)(qing)(qing)遠離(li)易(yi)燃(ran)易(yi)爆物品。請(qing)(qing)(qing)勿(wu)(wu)使(shi)(shi)水(shui)及(ji)其他液(ye)體進(jin)入(ru)本(ben)(ben)機(ji)(ji)器(qi)。請(qing)(qing)(qing)勿(wu)(wu)使(shi)(shi)導(dao)電(dian)(dian)體或(huo)金屬屑進(jin)入(ru)本(ben)(ben)機(ji)(ji)器(qi),及(ji)加(jia)熱體上電(dian)(dian)磁(ci)(ci)線(xian)圈。請(qing)(qing)(qing)勿(wu)(wu)在電(dian)(dian)路漏(lou)電(dian)(dian)情況下(xia)使(shi)(shi)用(yong)本(ben)(ben)機(ji)(ji)器(qi)。請(qing)(qing)(qing)勿(wu)(wu)將本(ben)(ben)機(ji)(ji)器(qi)平放,豎立(li),以(yi)有利于散熱。請(qing)(qing)(qing)勿(wu)(wu)在電(dian)(dian)磁(ci)(ci)線(xian)圈周(zhou)圍放置任何鐵磁(ci)(ci)質(zhi)材料。電(dian)(dian)源(yuan)輸入(ru)、高(gao)頻輸出嚴禁使(shi)(shi)用(yong)鋁質(zhi)接線(xian)鼻。在生產(chan)停(ting)止,不需要(yao)加(jia)熱時,嚴禁立(li)即切(qie)斷電(dian)(dian)源(yuan);需要(yao)等(deng)散熱風扇停(ting)止轉(zhuan)動后(hou)(hou),再(zai)切(qie)斷電(dian)(dian)源(yuan)。請(qing)(qing)(qing)及(ji)時清理灰(hui)塵,保證其干(gan)凈、整潔。新安裝機(ji)(ji)器(qi),調(diao)試(shi)前測試(shi)電(dian)(dian)感(gan)量,待電(dian)(dian)感(gan)量符合(he)要(yao)求后(hou)(hou)再(zai)試(shi)機(ji)(ji)。非(fei)專業人(ren)士請(qing)(qing)(qing)勿(wu)(wu)調(diao)動本(ben)(ben)機(ji)(ji)器(qi),如(ru)有問(wen)題請(qing)(qing)(qing)和經(jing)銷商或(huo)廠家聯系。接入(ru)電(dian)(dian)源(yuan)電(dian)(dian)壓應(ying)符合(he)本(ben)(ben)機(ji)(ji)器(qi)電(dian)(dian)氣規(gui)格中要(yao)求的參數。
電(dian)磁(ci)(ci)加(jia)熱器的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)升不(bu)上(shang)去(qu)該怎么辦?第二種解(jie)決方法:當(dang)造(zao)粒機類似于大功率(lv)時(shi),安裝電(dian)磁(ci)(ci)加(jia)熱器后,溫(wen)(wen)度(du)(du)總(zong)(zong)達不(bu)到。而且電(dian)磁(ci)(ci)加(jia)熱器也直在(zai)工作(zuo)(zuo),電(dian)流也正(zheng)常,但(dan)是(shi)(shi)(shi)溫(wen)(wen)度(du)(du)總(zong)(zong)上(shang)不(bu)去(qu),般這種情況(kuang)是(shi)(shi)(shi)功率(lv)不(bu)夠大。目(mu)前是(shi)(shi)(shi)市面(mian)上(shang)的(de)(de)(de)(de)些(xie)中間商用40kw貼個子就說是(shi)(shi)(shi)60kw電(dian)磁(ci)(ci)加(jia)熱器的(de)(de)(de)(de)事件(jian)見過(guo)許(xu)多,我(wo)們可(ke)(ke)以(yi)通過(guo)電(dian)流確(que)定下(xia)功率(lv)到底是(shi)(shi)(shi)多少,如果確(que)定是(shi)(shi)(shi)實際(ji)(ji)功率(lv)太(tai)小了,可(ke)(ke)以(yi)加(jia)大實際(ji)(ji)功率(lv)來實現(xian)。要是(shi)(shi)(shi)確(que)定實際(ji)(ji)功率(lv)不(bu)小了,這是(shi)(shi)(shi)由炮筒的(de)(de)(de)(de)材(cai)料引起來的(de)(de)(de)(de),不(bu)同(tong)材(cai)質在(zai)不(bu)同(tong)的(de)(de)(de)(de)工作(zuo)(zuo)頻率(lv)時(shi)吸收熱量也不(bu)同(tong)。應該是(shi)(shi)(shi)嘗試(shi)(shi)(shi)增(zeng)加(jia)諧振(zhen)電(dian)容容量,讓(rang)Q值增(zeng)加(jia),提(ti)高線圈高頻電(dian)流。可(ke)(ke)以(yi)使炮筒內外溫(wen)(wen)度(du)(du)均勻的(de)(de)(de)(de)來達到提(ti)高炮筒的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)。如果各(ge)個方面(mian)的(de)(de)(de)(de)條件(jian)可(ke)(ke)以(yi)的(de)(de)(de)(de)話,可(ke)(ke)以(yi)試(shi)(shi)(shi)著(zhu)去(qu)換掉(diao)炮筒試(shi)(shi)(shi)試(shi)(shi)(shi)。
電磁式加(jia)熱方(fang)式與電阻絲(si)加(jia)熱方(fang)式對比:
1、節能效(xiao)果好:相比原(yuan)電(dian)阻絲加(jia)熱圈(quan)節電(dian)效(xiao)果都在30%以(yi)上,相對不同的原(yuan)料、生產不同的產品,節電(dian)效(xiao)果有(you)所變化。但在已使用的產品中節電(dian)效(xiao)率大可達75%。
2、環(huan)保效果好(hao):可顯著(zhu)降低環(huan)境溫度。
3、使用壽命長:加熱(re)圈連續運行溫度只有(you)100℃左右,不存(cun)在(zai)加熱(re)圈更(geng)換問題。相對于電阻(zu)絲加熱(re)減少了二(er)次投入。
4、可提高產品(pin)(pin)產量:由于該產品(pin)(pin)的發熱效率高,能顯著減少升(sheng)溫(wen)時間,提高產品(pin)(pin)產量。
5、性能(neng)安全(quan)可靠:品質(zhi)優良、高度自(zi)動化、無須人工調節。
電磁加熱器用(yong)薄(bo)膜(mo)電容的要求和注意事項:
1、耐壓(ya)選(xuan)擇不當:例(li)如,交流輸入端,380V的(de)線(xian)電壓(ya),EMI電路(lu)用(yong)的(de)電容(rong)器,三角形接法(fa),部分工程師選(xuan)擇MKP-X2 275V.AC (這(zhe)會導致電容(rong)擊穿)。例(li)如,LC諧振回路(lu),很多工程師以(yi)為半橋諧振電容(rong),耐壓(ya)只是(shi)直流母(mu)線(xian)537V的(de)半即可(實際上(shang)這(zhe)是(shi)嚴重錯誤(wu)的(de))。國內的(de)機芯,有使用(yong)的(de)薄膜電容(rong)器耐壓(ya)等1200V 1600V 2000V 2500V 3000V 4000V 需(xu)要根據自己的(de)實際電路(lu)來(lai)選(xuan)擇。正確的(de)方式是(shi)用(yong)示(shi)波(bo)器加高壓(ya)探頭,實際測(ce)量下機芯在大(da)功率(lv)的(de)時候,諧振電壓(ya)的(de)波(bo)形。
2、電(dian)(dian)(dian)流(liu)選擇(ze)不當:很多企(qi)業的(de)工程師,研發人員,對于直流(liu)母(mu)線支撐電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi),LC諧振(zhen)電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi),電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)的(de)電(dian)(dian)(dian)流(liu)方(fang)面根本(ben)就(jiu)沒經(jing)過具體(ti)計(ji)算和(he)實際(ji)測(ce)(ce)量,造成(cheng)電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)工作溫度非常高,大(da)大(da)縮短薄膜電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)的(de)使(shi)用壽命,嚴(yan)重(zhong)的(de)出(chu)現短時間就(jiu)炸(zha)掉電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)了。正確的(de)方(fang)式,就(jiu)是用電(dian)(dian)(dian)流(liu)互感(gan)器(qi)(qi)(qi)測(ce)(ce)量下諧振(zhen)回(hui)路的(de)電(dian)(dian)(dian)流(liu)值,還有通過機子在(zai)老(lao)化(hua)的(de)時候測(ce)(ce)測(ce)(ce)電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)的(de)溫升是否正常。
3、接線方式不(bu)(bu)當(dang)(dang):在設計電(dian)磁(ci)加(jia)熱機芯的時候,很多情(qing)況下需要(yao)多個薄(bo)膜電(dian)容(rong)器并聯使用.并聯的好處就是(shi)(shi)(shi)可(ke)以增加(jia)過流(liu)能力(li),降低溫(wen)升(sheng).但是(shi)(shi)(shi)并聯電(dian)路(lu),大的問(wen)題是(shi)(shi)(shi)過流(liu)不(bu)(bu)均(jun).由(you)于接線方式的不(bu)(bu)當(dang)(dang),往(wang)往(wang)造成并聯的幾只電(dian)容(rong)器,某個位置的電(dian)容(rong)器溫(wen)度高,容(rong)易(yi)先壞掉。
電(dian)(dian)磁加(jia)(jia)熱(re)(re)(re)和傳(chuan)統電(dian)(dian)阻加(jia)(jia)熱(re)(re)(re)對比:傳(chuan)統電(dian)(dian)阻加(jia)(jia)熱(re)(re)(re)熱(re)(re)(re)損失大(da):現有企業專用(yong)(yong)的加(jia)(jia)熱(re)(re)(re)方式,是由電(dian)(dian)阻絲(si)(si)繞制,圈的內外雙面(mian)發熱(re)(re)(re),其(qi)內面(mian)(緊貼料(liao)筒部分)的熱(re)(re)(re)傳(chuan)導到料(liao)筒上,而外面(mian)的熱(re)(re)(re)量(liang)大(da)部分散(san)失到空氣(qi)中,造成電(dian)(dian)能(neng)的直(zhi)接損失、浪費。環境(jing)(jing)溫(wen)度(du)上升(sheng): 由于(yu)熱(re)(re)(re)量(liang)大(da)量(liang)散(san)失,周圍環境(jing)(jing)溫(wen)度(du)升(sheng)高,尤(you)其(qi)是夏天(tian)對生產環境(jing)(jing)影(ying)響很(hen)大(da),現場工作溫(wen)度(du)有的已經超過了45度(du),有些企業不得不采(cai)用(yong)(yong)空調降低溫(wen)度(du),這又造成能(neng)源的二次(ci)浪費。使用(yong)(yong)壽命(ming)短、維修量(liang)大(da): 電(dian)(dian)熱(re)(re)(re)管由于(yu)采(cai)用(yong)(yong)電(dian)(dian)阻絲(si)(si)發熱(re)(re)(re),其(qi)加(jia)(jia)熱(re)(re)(re)溫(wen)度(du)高達300度(du)左(zuo)右,熱(re)(re)(re)滯后較大(da),不易精確(que)控溫(wen),電(dian)(dian)阻絲(si)(si)容(rong)易因高溫(wen)老化而燒斷。常用(yong)(yong)電(dian)(dian)熱(re)(re)(re)圈使用(yong)(yong)壽命(ming)約半年,因此,維修的工作量(liang)相對較大(da)。
此外(wai),挑選(xuan)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)時(shi),還要考(kao)慮(lv)(lv)其(qi)(qi)(qi)(qi)線(xian)(xian)(xian)(xian)(xian)徑,材質,耐(nai)溫(wen)(wen)耐(nai)壓性能等。這些(xie)也都是(shi)由其(qi)(qi)(qi)(qi)使(shi)(shi)用(yong)條件決定(ding)(ding)的(de)(de)(de)。在實際(ji)選(xuan)配(pei)過程中(zhong)(zhong),先(xian)要根據加(jia)熱(re)需(xu)求確定(ding)(ding)所需(xu)設備(bei)(bei)功(gong)(gong)率(lv),然后就可(ke)以知道其(qi)(qi)(qi)(qi)輸(shu)出(chu)電(dian)流(liu)值,進而確定(ding)(ding)線(xian)(xian)(xian)(xian)(xian)徑、材質,然后視現場的(de)(de)(de)溫(wen)(wen)度情(qing)況,散熱(re)情(qing)況等考(kao)慮(lv)(lv)其(qi)(qi)(qi)(qi)耐(nai)溫(wen)(wen)性能。如(ru)果(guo)挑選(xuan)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)時(shi)沒(mei)有(you)(you)(you)考(kao)慮(lv)(lv)到這些(xie)因(yin)素(su),就很(hen)容易出(chu)現設備(bei)(bei)故障,例(li)如(ru)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)被燒壞,加(jia)熱(re)效(xiao)率(lv)低下(xia),線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)不(bu)(bu)(bu)(bu)(bu)耐(nai)用(yong)等問(wen)題。輕則影響生(sheng)產,重(zhong)則造成人身事故。二(er)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)繞(rao)制(zhi):表面看(kan)來,線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)繞(rao)制(zhi)這工作(zuo)似乎是(shi)沒(mei)技術含量的(de)(de)(de),不(bu)(bu)(bu)(bu)(bu)就是(shi)把線(xian)(xian)(xian)(xian)(xian)材繞(rao)下(xia)組成個(ge)(ge)(ge)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)嘛,這誰不(bu)(bu)(bu)(bu)(bu)會?但實際(ji)上并沒(mei)有(you)(you)(you)那么簡單,線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)的(de)(de)(de)繞(rao)制(zhi)需(xu)要考(kao)慮(lv)(lv)到疊(die)加(jia)、干(gan)擾、散熱(re)、距離、感(gan)(gan)(gan)量匹配(pei)等因(yin)素(su)。不(bu)(bu)(bu)(bu)(bu)同功(gong)(gong)率(lv)的(de)(de)(de)電(dian)磁(ci)(ci)加(jia)熱(re)器其(qi)(qi)(qi)(qi)所需(xu)要的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)電(dian)感(gan)(gan)(gan)量是(shi)不(bu)(bu)(bu)(bu)(bu)樣(yang)的(de)(de)(de),只(zhi)有(you)(you)(you)實際(ji)電(dian)感(gan)(gan)(gan)量和理論(lun)值直,才能保證電(dian)磁(ci)(ci)加(jia)熱(re)器的(de)(de)(de)功(gong)(gong)率(lv)大化。例(li)如(ru),臺(tai)30KW的(de)(de)(de)電(dian)磁(ci)(ci)加(jia)熱(re)器,其(qi)(qi)(qi)(qi)理論(lun)電(dian)感(gan)(gan)(gan)量是(shi)240μH,線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)繞(rao)制(zhi)時(shi),只(zhi)有(you)(you)(you)實際(ji)感(gan)(gan)(gan)量為240μH,其(qi)(qi)(qi)(qi)功(gong)(gong)率(lv)才有(you)(you)(you)可(ke)能完全達(da)到。如(ru)果(guo)實際(ji)感(gan)(gan)(gan)量是(shi)100μH、150μH、300μH、400μH,那其(qi)(qi)(qi)(qi)這臺(tai)設備(bei)(bei)的(de)(de)(de)實際(ji)使(shi)(shi)用(yong)功(gong)(gong)率(lv)可(ke)能就只(zhi)有(you)(you)(you)20KW,15KW,甚至根本啟動(dong)不(bu)(bu)(bu)(bu)(bu)了(le)。三適(shi)用(yong)見場:電(dian)磁(ci)(ci)加(jia)熱(re)器的(de)(de)(de)廣泛應用(yong)性決定(ding)(ding)了(le)其(qi)(qi)(qi)(qi)現場使(shi)(shi)用(yong)情(qing)況的(de)(de)(de)復雜。在電(dian)磁(ci)(ci)加(jia)熱(re)器眾多(duo)的(de)(de)(de)使(shi)(shi)用(yong)域中(zhong)(zhong),食(shi)品(pin)、塑(su)料、化工、印(yin)刷、供暖、垃圾處(chu)理,每個(ge)(ge)(ge)行業的(de)(de)(de)應用(yong)場景都不(bu)(bu)(bu)(bu)(bu)同,就是(shi)同個(ge)(ge)(ge)行業中(zhong)(zhong),每個(ge)(ge)(ge)客戶的(de)(de)(de)使(shi)(shi)用(yong)現場也有(you)(you)(you)很(hen)大的(de)(de)(de)差別。所以,電(dian)磁(ci)(ci)線(xian)(xian)(xian)(xian)(xian)圈(quan)(quan)不(bu)(bu)(bu)(bu)(bu)具有(you)(you)(you)普遍適(shi)用(yong)性,是(shi)種不(bu)(bu)(bu)(bu)(bu)同使(shi)(shi)用(yong)場景有(you)(you)(you)不(bu)(bu)(bu)(bu)(bu)同繞(rao)法的(de)(de)(de)非標(biao)配(pei)件。
挑選好(hao)的電磁加熱器(qi)有什技巧(qiao)?
1、性(xing)能(neng):隨著科(ke)學技術的進步(bu),電磁加(jia)(jia)熱(re)器(qi)的功(gong)能(neng)集成程度非常(chang)高,些產品甚至(zhi)集中了各(ge)(ge)行各(ge)(ge)業工廠加(jia)(jia)熱(re)設(she)備等(deng)等(deng)諸多(duo)功(gong)能(neng),那(nei)么,是不是功(gong)能(neng)越多(duo)就越好呢?這(zhe)不定,因為很(hen)多(duo)功(gong)能(neng)或許客戶在以后的日子中根本用不上。般工廠在考慮和挑選(xuan)電磁加(jia)(jia)熱(re)器(qi)的功(gong)能(neng)的時(shi)候,定要根據自己(ji)的實(shi)際需要購買,注重自己(ji)需要多(duo)大功(gong)率的電磁加(jia)(jia)熱(re)控制器(qi)來選(xuan)擇(ze)控制器(qi)。
2、節(jie)能(neng)與環保:眼下階梯電(dian)價(jia)即將實施,選擇(ze)款(kuan)節(jie)能(neng)的產(chan)品(pin)也十分(fen)必要,畢(bi)竟(jing)電(dian)用的越多,單價(jia)也將升高(gao),而(er)且,本身電(dian)磁(ci)加熱器也是高(gao)功(gong)率電(dian)器,因此選購(gou)的時候更應該注意其能(neng)耗。當(dang)前,市場上銷售的電(dian)磁(ci)加熱控制器,很多新型產(chan)品(pin)都使用了節(jie)能(neng)與環保的技術與設計,這對(dui)于(yu)消費(fei)者來說是有利的。
使用造(zao)粒機電磁加熱(re)器(qi)時要知道的常識:
1、我們要把(ba)造粒機(ji)電磁加熱(re)器(qi)安置在(zai)個牢固(gu)的平臺上或掛在(zai)設備上,其(qi)附近不宜溫度過高,以防止散熱(re)不好導(dao)致過熱(re)保護。
2、不要將控制(zhi)器安裝在潮濕(shi)的環境中,防止水(shui)蒸汽進(jin)入電(dian)箱(xiang)后,易(yi)在緣(yuan)(yuan)介(jie)質表(biao)面凝結,降低其緣(yuan)(yuan)性能,造成漏(lou)電(dian)事故。
3、外部電源(yuan)在接(jie)入(ru)電磁加熱器(qi)前,應安裝獨(du)立的(de)電源(yuan)空氣開(kai)關保護(hu)裝置。并(bing)將金屬外殼(ke)要(yao)可靠接(jie)地。在使用過程中,不要(yao)輕易拆除(chu)其接(jie)地導線,因為(wei)接(jie)地措(cuo)施(shi)是防止(zhi)觸電的(de)后道保護(hu)措(cuo)施(shi)。
4、要(yao)定期清理(li)散熱器,保證產(chan)品通風良好。要(yao)經常檢(jian)查(cha)產(chan)品的進風口(kou)及散熱風扇(shan),防止進風口(kou)處(chu)堵塞或散熱風扇(shan)卡(ka)死,避免因(yin)過熱停機保護。
