內蒙古注塑機電磁加熱器哪個好

作者:中輝電器     來源:www.shenzhentuliao.cn    發布時間:2019/4/28 9:31:08

電磁加熱器的質量是(shi)由什么決定呢:

、重要(yao)元器(qi)件(jian)的(de)(de)選(xuan)擇。電(dian)磁加(jia)熱控(kong)制(zhi)器(qi)功(gong)率部分核(he)心元器(qi)件(jian)是IGBT模塊(kuai),IGBT的(de)(de)優(you)劣直(zhi)接影響到機器(qi)壽命長短(duan),建(jian)議直(zhi)接從國內代(dai)理商那進貨,否則買到高仿或者翻新的(de)(de)IGBT模塊(kuai)仍然會出現質量(liang)問題。

二、主板(ban)的(de)(de)(de)選擇。電磁(ci)加熱控制器(qi)的(de)(de)(de)主板(ban)分為(wei)三部分,電源(yuan)板(ban)、信號板(ban)和(he)(he)驅動(dong)板(ban),要(yao)想保證機(ji)器(qi)長時間(jian)穩定工作,主板(ban)要(yao)有(you)各種(zhong)保護(hu):過(guo)載、過(guo)流和(he)(he)過(guo)熱,電磁(ci)加熱器(qi)應(ying)用現場(chang)環(huan)境很(hen)復雜,比如(ru)干(gan)擾等,旦出現非正常情況,主板(ban)應(ying)該能很(hen)快反應(ying)并(bing)保護(hu)機(ji)器(qi),防止非正常因素(su)損壞機(ji)器(qi),特(te)別(bie)是(shi)(shi)IGBT。目前市場(chang)上很(hen)多所謂的(de)(de)(de)電磁(ci)加熱器(qi)廠家的(de)(de)(de)主板(ban)并(bing)不是(shi)(shi)自(zi)己(ji)(ji)開發的(de)(de)(de),而是(shi)(shi)直接購買(mai)的(de)(de)(de),然后自(zi)己(ji)(ji)組裝的(de)(de)(de),般出現問(wen)題(ti),就直接讓客戶換主板(ban),并(bing)不能發現問(wen)題(ti)的(de)(de)(de)根源(yuan)所在。

三、高(gao)(gao)溫線(xian)的(de)(de)選擇。高(gao)(gao)溫線(xian)是(shi)(shi)(shi)很多(duo)客(ke)戶容易忽視(shi)的(de)(de)個問題(ti),目前市場上國(guo)標(biao)(biao)的(de)(de)高(gao)(gao)溫線(xian)很難(nan)買到(dao),不(bu)要相信商家的(de)(de)所說的(de)(de),定睜大(da)眼睛,不(bu)要嫌麻煩,從重(zhong)量和材(cai)質上鑒定下(xia)是(shi)(shi)(shi)否是(shi)(shi)(shi)國(guo)標(biao)(biao)高(gao)(gao)溫線(xian),如果用(yong)到(dao)非標(biao)(biao)高(gao)(gao)溫線(xian),不(bu)僅僅影(ying)(ying)響(xiang)(xiang)機器(qi)(qi)(qi)壽命,還會(hui)影(ying)(ying)響(xiang)(xiang)整機的(de)(de)效(xiao)率,大(da)家應該(gai)重(zhong)視(shi)這(zhe)個問題(ti)。四經(jing)驗(yan)的(de)(de)差(cha)別。電(dian)(dian)(dian)磁(ci)加(jia)熱(re)器(qi)(qi)(qi)安(an)裝(zhuang)的(de)(de)好,和安(an)裝(zhuang)的(de)(de)不(bu)好效(xiao)果是(shi)(shi)(shi)很大(da)區別,這(zhe)點需要豐富的(de)(de)安(an)裝(zhuang)實例,光靠幾組數據是(shi)(shi)(shi)分(fen)析不(bu)出來(lai)的(de)(de),根(gen)本沒有(you)這(zhe)樣(yang)的(de)(de)經(jing)驗(yan)來(lai)支(zhi)撐(cheng),完(wan)全靠理論(lun)在安(an)裝(zhuang)。人家說臺(tai)同型號(hao)的(de)(de)電(dian)(dian)(dian)磁(ci)加(jia)熱(re)器(qi)(qi)(qi),裝(zhuang)在同型號(hao)的(de)(de)注(zhu)塑機上,為什么個省電(dian)(dian)(dian)40%以上,個剛剛夠理論(lun)數據的(de)(de)30%,這(zhe)個不(bu)僅是(shi)(shi)(shi)機器(qi)(qi)(qi)的(de)(de)差(cha)異,電(dian)(dian)(dian)磁(ci)加(jia)熱(re)器(qi)(qi)(qi)的(de)(de)安(an)裝(zhuang)位置,線(xian)圈(quan)長短都(dou)有(you)影(ying)(ying)響(xiang)(xiang),如果是(shi)(shi)(shi)采(cai)用(yong)多(duo)組小(xiao)功率的(de)(de)電(dian)(dian)(dian)磁(ci)加(jia)熱(re)器(qi)(qi)(qi),這(zhe)個差(cha)異就(jiu)更為明顯。電(dian)(dian)(dian)磁(ci)加(jia)熱(re)行業有(you)個測試(shi)機器(qi)(qi)(qi)是(shi)(shi)(shi)否裝(zhuang)好的(de)(de)方(fang)法,就(jiu)是(shi)(shi)(shi)讓(rang)電(dian)(dian)(dian)磁(ci)加(jia)熱(re)器(qi)(qi)(qi)工作2分(fen)鐘(zhong)左右,休息1分(fen)鐘(zhong)左右。

電磁加(jia)熱控(kong)制(zhi)器的(de)兩種啟動方式:般電磁加(jia)熱器可(ke)以有(you)兩種啟動方式,

種(zhong)是(shi)軟(ruan)啟(qi)動(dong)方(fang)式,另(ling)種(zhong)是(shi)硬啟(qi)動(dong)方(fang)法(fa)。軟(ruan)啟(qi)動(dong)方(fang)法(fa)是(shi)用信號(hao)線(xian)(xian)(xian)端接(jie)(jie)(jie)入(ru)+號(hao),另(ling)端接(jie)(jie)(jie)入(ru)號(hao),當接(jie)(jie)(jie)通后功(gong)(gong)率(lv)(lv)(lv)則輸出,電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)就(jiu)(jiu)正常工(gong)作加(jia)(jia)(jia)(jia)熱(re)(re)(re)。當斷開(kai)信號(hao)線(xian)(xian)(xian)后則功(gong)(gong)率(lv)(lv)(lv)就(jiu)(jiu)不輸出,電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)就(jiu)(jiu)停(ting)(ting)止加(jia)(jia)(jia)(jia)熱(re)(re)(re)。這種(zhong)叫(jiao)做軟(ruan)啟(qi)動(dong)方(fang)式,使用軟(ruan)啟(qi)動(dong)方(fang)式控(kong)(kong)制(zhi)(zhi)(zhi)電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)的(de)優勢(shi)是(shi)控(kong)(kong)制(zhi)(zhi)(zhi)電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)方(fang)便,可(ke)以(yi)自由接(jie)(jie)(jie)入(ru)或(huo)斷開(kai)來控(kong)(kong)制(zhi)(zhi)(zhi)電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)工(gong)作或(huo)停(ting)(ting)止。軟(ruan)啟(qi)動(dong)的(de)另(ling)外(wai)頭接(jie)(jie)(jie)的(de)是(shi)溫(wen)控(kong)(kong)器(qi)或(huo)繼電(dian)器(qi),使用溫(wen)控(kong)(kong)器(qi)可(ke)以(yi)利(li)于(yu)控(kong)(kong)制(zhi)(zhi)(zhi)電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)加(jia)(jia)(jia)(jia)熱(re)(re)(re)的(de)溫(wen)度,和調節溫(wen)度的(de)大小(xiao)。當個(ge)(ge)(ge)溫(wen)區只有組(zu)電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)的(de)時候,軟(ruan)啟(qi)動(dong)方(fang)法(fa)只要要信號(hao)線(xian)(xian)(xian)接(jie)(jie)(jie)通+號(hao)和號(hao)就(jiu)(jiu)可(ke)以(yi)了,當個(ge)(ge)(ge)溫(wen)區有兩(liang)個(ge)(ge)(ge)電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)的(de)時候,就(jiu)(jiu)要把這兩(liang)個(ge)(ge)(ge)控(kong)(kong)制(zhi)(zhi)(zhi)主板(ban)的(de)+號(hao)信號(hao)線(xian)(xian)(xian)并(bing)聯,軟(ruan)啟(qi)動(dong)信號(hao)線(xian)(xian)(xian)號(hao)并(bing)聯,當控(kong)(kong)制(zhi)(zhi)(zhi)+接(jie)(jie)(jie)通的(de)時候功(gong)(gong)率(lv)(lv)(lv)就(jiu)(jiu)輸出,電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)器(qi)就(jiu)(jiu)會正常加(jia)(jia)(jia)(jia)熱(re)(re)(re)工(gong)作,當斷開(kai)十接(jie)(jie)(jie)通,電(dian)磁(ci)加(jia)(jia)(jia)(jia)熱(re)(re)(re)控(kong)(kong)制(zhi)(zhi)(zhi)器(qi)就(jiu)(jiu)停(ting)(ting)止加(jia)(jia)(jia)(jia)熱(re)(re)(re)。

另種啟(qi)動(dong)方(fang)式就是硬(ying)啟(qi)動(dong)方(fang)式,就是將+號信(xin)線固定。但這種方(fang)式不能靈活控制電(dian)磁加熱(re)器。相對比于硬(ying)啟(qi)動(dong)方(fang)式來(lai)說,軟啟(qi)動(dong)方(fang)式更(geng)具有優勢,軟啟(qi)動(dong)電(dian)磁加熱(re)器因使用(yong)方(fang)便(bian),利于控制,所以大多數都是使用(yong)軟啟(qi)動(dong)來(lai)控制電(dian)磁加熱(re)器的。

電磁(ci)加(jia)(jia)熱(re)器(qi)(qi)的(de)(de)溫(wen)(wen)(wen)度升不上(shang)(shang)(shang)去該怎么(me)辦?種(zhong)解決方法(fa):當(dang)為注塑(su)機(ji)、吹膜機(ji)類似于小(xiao)功(gong)率時(shi),安裝電磁(ci)加(jia)(jia)熱(re)器(qi)(qi)后有(you)(you)(you)些(xie)機(ji)器(qi)(qi)溫(wen)(wen)(wen)度總是(shi)差點點。然(ran)后有(you)(you)(you)的(de)(de)客(ke)戶就(jiu)把功(gong)率調節大(da)些(xie)還(huan)(huan)是(shi)樣,有(you)(you)(you)的(de)(de)客(ke)戶還(huan)(huan)干脆就(jiu)把溫(wen)(wen)(wen)度直接設定調高,大(da)家都覺(jue)得(de)(de)很(hen)奇怪,有(you)(you)(you)時(shi)候總感覺(jue)就(jiu)是(shi)看(kan)不懂,摸不著(zhu)頭(tou)腦。其實(shi)呢,這個大(da)多數的(de)(de)原因不是(shi)功(gong)率安裝小(xiao),而且由于原來機(ji)器(qi)(qi)的(de)(de)溫(wen)(wen)(wen)控制器(qi)(qi)輸(shu)出的(de)(de)PID運算(suan)方法(fa)引起來的(de)(de),啟動信號很(hen)短(duan),有(you)(you)(you)些(xie)短(duan)到(dao)1-5秒(miao)以內,電磁(ci)加(jia)(jia)熱(re)器(qi)(qi)都還(huan)(huan)沒(mei)有(you)(you)(you)來得(de)(de)及開始(shi)工(gong)作,就(jiu)又斷了。所以導致電磁(ci)加(jia)(jia)熱(re)器(qi)(qi)大(da)多數時(shi)間(jian)處于停(ting)止狀態(tai),基本上(shang)(shang)(shang)是(shi)沒(mei)有(you)(you)(you)在加(jia)(jia)熱(re)的(de)(de)。因為加(jia)(jia)熱(re)的(de)(de)溫(wen)(wen)(wen)度總是(shi)達不到(dao)的(de)(de)。這時(shi)我們可(ke)(ke)以調節機(ji)器(qi)(qi)中的(de)(de)斷開延(yan)時(shi)工(gong)作時(shi)間(jian),來達到(dao)溫(wen)(wen)(wen)度要(yao)(yao)求(qiu)。詳細的(de)(de)方法(fa)使(shi)用(yong)說明書(shu)上(shang)(shang)(shang)也有(you)(you)(you),調節為8-15秒(miao),默(mo)認為0秒(miao),般為8秒(miao)鐘(zhong)就(jiu)可(ke)(ke)以實(shi)現沒(mei)有(you)(you)(you)溫(wen)(wen)(wen)差了,但是(shi)得(de)(de)注意哦,不要(yao)(yao)調節到(dao)太大(da),否則溫(wen)(wen)(wen)度可(ke)(ke)能會超(chao)的(de)(de)。

內蒙古注塑機電磁加熱器哪個好

電磁加熱器的全橋和(he)半橋的工(gong)作原理的同異:

、相(xiang)同:均(jun)是通(tong)過(guo)(guo)系列電(dian)路處理技術將普通(tong)交流(liu)(liu)(liu)電(dian)(220V、380V)轉化成(cheng)高(gao)頻直(zhi)流(liu)(liu)(liu)電(dian)流(liu)(liu)(liu),通(tong)過(guo)(guo)做功線盤產(chan)生強烈電(dian)渦流(liu)(liu)(liu),并(bing)與(yu)相(xiang)應專用金(jin)屬(shu)(shu)(shu)材質感應產(chan)生激烈電(dian)磁場,直(zhi)接(jie)促使相(xiang)應金(jin)屬(shu)(shu)(shu)材質內部(bu)原(yuan)子速激蕩(dang)碰(peng)撞(zhuang),從(cong)而使得(de)相(xiang)應金(jin)屬(shu)(shu)(shu)材質自身快速發熱產(chan)生高(gao)溫,普遍(bian)用于工業(ye)塑(su)膠(jiao)機械(xie)料筒上加熱,如拉絲機、吹膜機,造(zao)粒機,注塑(su)機,擠出機等(deng)等(deng)!

二、不(bu)同對交流電的承接轉化處(chu)理技術上:

1、全橋:采(cai)用雙路驅動(dong)技術,利用雙IGBT逆變模(mo)塊分別承接轉化交流(liu)電的上玄(xuan)波和下(xia)玄(xuan)波電流(liu),產生的高頻電流(liu)波形完整(zheng)、清晰(xi)、穩(wen)定。

2、半橋:采(cai)用單路驅動技術(shu),利用單IGBT逆(ni)變模塊分(fen)別承接轉(zhuan)化交(jiao)流(liu)電(dian)的上玄波,結(jie)合相(xiang)應附加電(dian)路配置吸收下玄波電(dian)流(liu)進行放(fang)電(dian)補充,產(chan)生的高頻(pin)電(dian)流(liu)波形相(xiang)對(dui)完整。

三、對相應(ying)專(zhuan)用(yong)鍋具的負載(zai)感應(ying)上:

1、全橋:因(yin)電(dian)(dian)流轉化技(ji)術配置(zhi)效率(lv)高(gao),可負載較高(gao)電(dian)(dian)感負荷,電(dian)(dian)轉熱效率(lv)相(xiang)應(ying)較高(gao)。

2、半(ban)橋:因電(dian)(dian)流轉(zhuan)(zhuan)化技術配置(zhi)效率稍低,可負(fu)載較(jiao)低電(dian)(dian)感負(fu)荷(he),電(dian)(dian)轉(zhuan)(zhuan)熱效率相(xiang)應較(jiao)低。

電(dian)磁(ci)加(jia)熱線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)(rao)法(fa):電(dian)磁(ci)加(jia)熱線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)根據(ju)加(jia)熱體的(de)(de)形狀、大(da)小(xiao)而異,纏(chan)繞(rao)(rao)(rao)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)用線(xian)(xian)(xian)(xian)長(chang)(chang)度(du)(du)及電(dian)感量會(hui)有(you)點(dian)差(cha)別。電(dian)磁(ci)感應(ying)加(jia)熱器每個功率用線(xian)(xian)(xian)(xian)的(de)(de)線(xian)(xian)(xian)(xian)徑(jing)大(da)小(xiao)般都是固定(ding)的(de)(de),線(xian)(xian)(xian)(xian)長(chang)(chang)也(ye)是基本(ben)固定(ding)的(de)(de)(加(jia)熱體過大(da)線(xian)(xian)(xian)(xian)長(chang)(chang)會(hui)加(jia)長(chang)(chang)比如直(zhi)(zhi)徑(jing)100MM和直(zhi)(zhi)徑(jing)1000MM用同樣的(de)(de)線(xian)(xian)(xian)(xian)長(chang)(chang)直(zhi)(zhi)徑(jing)小(xiao)的(de)(de)加(jia)熱體繞(rao)(rao)(rao)的(de)(de)圈(quan)(quan)(quan)數(shu)多,繞(rao)(rao)(rao)在直(zhi)(zhi)徑(jing)大(da)的(de)(de)加(jia)熱體上圈(quan)(quan)(quan)數(shu)就是會(hui)少圈(quan)(quan)(quan)數(shu)少電(dian)感量就會(hui)小(xiao),這個時候就應(ying)該適當(dang)增加(jia)用線(xian)(xian)(xian)(xian)長(chang)(chang)度(du)(du),具體增加(jia)多少在沒(mei)有(you)經(jing)驗(yan)的(de)(de)情況下要測實際(ji)的(de)(de)電(dian)感量確定(ding)),纏(chan)繞(rao)(rao)(rao)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)(de)時候每圈(quan)(quan)(quan)之(zhi)間(jian)的(de)(de)間(jian)隔(ge)(ge)距(ju)離根據(ju)加(jia)熱溫區大(da)小(xiao)長(chang)(chang)度(du)(du)及線(xian)(xian)(xian)(xian)長(chang)(chang)而定(ding),可(ke)以(yi)圈(quan)(quan)(quan)圈(quan)(quan)(quan)緊密繞(rao)(rao)(rao),也(ye)可(ke)以(yi)緊密繞(rao)(rao)(rao)幾(ji)圈(quan)(quan)(quan)間(jian)隔(ge)(ge)幾(ji)公分再緊密繞(rao)(rao)(rao)幾(ji)圈(quan)(quan)(quan),也(ye)可(ke)以(yi)每圈(quan)(quan)(quan)與每圈(quan)(quan)(quan)之(zhi)間(jian)都間(jian)隔(ge)(ge)點(dian)距(ju)離繞(rao)(rao)(rao)。如果(guo)加(jia)熱體尺寸(cun)有(you)點(dian)小(xiao)還可(ke)以(yi)把(ba)線(xian)(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)(rao)(rao)成雙層或三層。

電磁加熱(re)器優點電磁感(gan)應(ying)加熱(re)優勢:

1、非接(jie)觸電磁感應(ying)加(jia)熱(re)。

2、耗電的 95% 轉化為工(gong)作熱(re)能。線圈損耗 ≈ 2%, 控制(zhi)單元(yuan)損耗 ≈ 2%, 緣隔(ge)熱(re)層可以將98%的能量保(bao)留在(zai)料(liao)筒上。

3、只(zhi)加熱料筒,而(er)螺桿保持冷卻。

4、消除加熱的慣性(xing)現象,升溫(wen)降溫(wen)迅速。

5、加熱無死角(jiao),整體(ti)料(liao)筒均(jun)勻加熱。

6、電磁(ci)線圈保持(chi)涼爽,因此(ci)壽命超長。

電(dian)磁加(jia)熱(re)器(qi)(qi)裝(zhuang)置后溫(wen)度不(bu)達標處理方法(fa),當造粒機類似大(da)功率(lv)時(shi),安裝(zhuang)電(dian)磁加(jia)熱(re)器(qi)(qi)后,溫(wen)度總達不(bu)到。電(dian)磁加(jia)熱(re)器(qi)(qi)也直工作,電(dian)流也正常,但溫(wen)度總上不(bu)去。般情況是(shi)功率(lv)不(bu)夠大(da)。可以加(jia)大(da)實際功率(lv)來(lai)實現(xian)。要是(shi)確定(ding)實際功率(lv)不(bu)小了,這是(shi)由(you)炮(pao)筒的材(cai)料引起的,不(bu)同材(cai)質的在不(bu)同的工作頻率(lv)時(shi)吸收熱(re)量也不(bu)同。應該嘗試增加(jia)諧振電(dian)容容量,讓Q值增加(jia),提高線圈高頻電(dian)流。可以使炮(pao)筒內外(wai)溫(wen)度均勻來(lai)達到提高炮(pao)筒的溫(wen)度。條件允話(hua)的話(hua),可以換掉炮(pao)筒試試。

風冷(leng)電(dian)(dian)(dian)(dian)磁加(jia)熱器之所(suo)以稱為(wei)風冷(leng),是(shi)由于它降溫(wen)的(de)(de)辦法(fa)是(shi)用電(dian)(dian)(dian)(dian)扇吹風降溫(wen)的(de)(de)方法(fa)。通常(chang)廠(chang)家的(de)(de)電(dian)(dian)(dian)(dian)磁加(jia)熱器里邊(bian)裝(zhuang)有(you)個電(dian)(dian)(dian)(dian)扇,當(dang)接上(shang)電(dian)(dian)(dian)(dian)源(yuan)作業(ye)后,電(dian)(dian)(dian)(dian)扇就會開端滾動,進行吹風降溫(wen),就和咱們電(dian)(dian)(dian)(dian)腦(nao)主(zhu)機里邊(bian)的(de)(de)電(dian)(dian)(dian)(dian)扇作業(ye)原理是(shi)相同(tong)的(de)(de)。風冷(leng)的(de)(de)優勢(shi):裝(zhuang)置便利,不需(xu)要再(zai)接入管道,也不需(xu)要對水質(zhi)有(you)所(suo)請(qing)求,不受氣候環境影響(xiang), 北方、南邊(bian)當(dang)地市場均(jun)可運用。
