電磁(ci)加熱器的全(quan)橋和半橋的應用表現(xian)的同異：

、據(ju)各自的(de)電路原(yuan)理的(de)差別決定：相同：均(jun)可達到(dao)使得相應料(liao)筒(tong)自身(shen)快速(su)發(fa)熱產生高溫，用于(yu)加(jia)工塑料(liao)的(de)功(gong)用。

二、功率段表現上不同：

1、全橋：對應(ying)檔位(wei)功(gong)率分配清(qing)晰、明確，反應(ying)迅速。

2、半橋(qiao)：對(dui)應(ying)檔位功率(lv)分配較模(mo)糊，反應(ying)相對(dui)合理。

三、發熱面表現上：

1、全橋：因可負載負荷較(jiao)高，發(fa)熱面較(jiao)大、較(jiao)均勻(yun)、層(ceng)次感(gan)能做到循(xun)序遞減，火焰(yan)仿真效果明(ming)顯。

2、半橋：因可負載負荷較低，發熱(re)面(mian)較小、均勻性稍遜、層次感分明(ming)，火焰仿真效果(guo)稍遜。

電磁加熱器的六種調(diao)節功率(lv)方式：

1、調頻法。

2、間隙加熱法。

3、移相脈(mo)寬調制法（全橋移相PWM控制）。

4、改變整(zheng)流電(dian)壓(ya)法(fa)。

5、脈沖功率輸出變(bian)壓器初抽(chou)頭切換法。

6、變壓器初抽頭切換、調(diao)頻、調(diao)壓法。

電磁感應加熱器應用(yong)超(chao)溫怎(zen)么辦：

1、熱電偶(ou)接頭兩端可以并個102P瓷片電容(rong)以消除(chu)高頻干擾。

2、檢查下炮(pao)筒接(jie)地(di)是(shi)否良好？嘗試炮(pao)筒強制接(jie)地(di)處理。

3、可以把線(xian)圈(quan)遠離下熱(re)電偶，減小干擾。

4、嘗試下用高溫(wen)布把熱電偶包住，讓它不要與炮(pao)筒接觸。

5、嘗試換條新的熱電偶。

6、嘗試下注塑(su)機控制(zhi)電(dian)(dian)腦中心加個Pai型(xing)慮波器，減小(xiao)電(dian)(dian)源干(gan)擾。

電(dian)(dian)阻(zu)線材加(jia)熱(re)(re)過程中電(dian)(dian)能浪費的原因：傳(chuan)統(tong)采暖行業(ye)普遍采用電(dian)(dian)阻(zu)導線和石(shi)英加(jia)熱(re)(re)方式，這種(zhong)(zhong)傳(chuan)統(tong)加(jia)熱(re)(re)方式熱(re)(re)效率低。電(dian)(dian)阻(zu)絲和石(shi)英主要通(tong)過電(dian)(dian)加(jia)熱(re)(re)，然(ran)后熱(re)(re)量轉移到(dao)料(liao)桶上。作為種(zhong)(zhong)加(jia)熱(re)(re)材料(liao)，這種(zhong)(zhong)加(jia)熱(re)(re)效果的大(da)熱(re)(re)利用率僅為50%左(zuo)(zuo)右，其余50%左(zuo)(zuo)右的熱(re)(re)量被排放(fang)到(dao)空氣中。傳(chuan)統(tong)電(dian)(dian)阻(zu)線材加(jia)熱(re)(re)方式的電(dian)(dian)能損(sun)耗高(gao)達50%。

電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)器(qi)(qi)可以多(duo)(duo)(duo)溫(wen)(wen)(wen)(wen)區(qu)控制(zhi)嗎？橡膠(jiao)(jiao)機多(duo)(duo)(duo)溫(wen)(wen)(wen)(wen)區(qu)加(jia)(jia)熱(re)早些(xie)年常用(yong)(yong)的(de)莫過于電(dian)(dian)(dian)(dian)阻加(jia)(jia)熱(re)，這種(zhong)加(jia)(jia)熱(re)方式熱(re)效率不(bu)高，耗電(dian)(dian)(dian)(dian)量比(bi)較(jiao)大。目(mu)前理想的(de)橡膠(jiao)(jiao)機多(duo)(duo)(duo)溫(wen)(wen)(wen)(wen)區(qu)加(jia)(jia)熱(re)建議(yi)采用(yong)(yong)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)器(qi)(qi)加(jia)(jia)熱(re)設備，通過電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)圈(quan)產生渦流使管(guan)道自(zi)身發熱(re)。管(guan)道加(jia)(jia)包(bao)層2.5公分的(de)保(bao)溫(wen)(wen)(wen)(wen)棉(mian)，這樣熱(re)量不(bu)容易外散到空(kong)氣。電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)圈(quan)的(de)外部溫(wen)(wen)(wen)(wen)度(du)只有幾十度(du)，工作室溫(wen)(wen)(wen)(wen)也(ye)會由(you)此而減低。晶星電(dian)(dian)(dian)(dian)子(zi)科技有限公司(si)據用(yong)(yong)戶親(qin)自(zi)測試，橡膠(jiao)(jiao)機多(duo)(duo)(duo)溫(wen)(wen)(wen)(wen)區(qu)改用(yong)(yong)電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)器(qi)(qi)相比(bi)電(dian)(dian)(dian)(dian)熱(re)圈(quan)至(zhi)少省電(dian)(dian)(dian)(dian)在(zai)30%以上，非常實(shi)用(yong)(yong)。橡膠(jiao)(jiao)機多(duo)(duo)(duo)溫(wen)(wen)(wen)(wen)區(qu)加(jia)(jia)熱(re)般(ban)為多(duo)(duo)(duo)條加(jia)(jia)熱(re)管(guan)道，條管(guan)道使用(yong)(yong)2組或者多(duo)(duo)(duo)組電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)器(qi)(qi)。實(shi)際(ji)要根據橡膠(jiao)(jiao)機加(jia)(jia)熱(re)管(guan)道尺寸而定。電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)板使用(yong)(yong)功率般(ban)為15kw-20kw電(dian)(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)器(qi)(qi)。

電磁感應加(jia)(jia)熱(re)器不加(jia)(jia)熱(re)原因主(zhu)要有以下三(san)點：

1、線路故(gu)障，沒電供及。

2、元件(jian)損(sun)壞，查找更(geng)換。

3、調(diao)整(zheng)(zheng)不(bu)當，重新調(diao)整(zheng)(zheng)適當數據。

電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)高能(neng)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)到(dao)(dao)多(duo)(duo)(duo)少(shao)(shao)度(du)(du)(du)？這(zhe)個問(wen)題很(hen)多(duo)(duo)(duo)朋(peng)友都問(wen)過我，那么用電(dian)(dian)(dian)磁(ci)感(gan)應(ying)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)能(neng)達(da)到(dao)(dao)多(duo)(duo)(duo)少(shao)(shao)度(du)(du)(du)呢？”這(zhe)取(qu)決(jue)于(yu)受熱(re)(re)(re)(re)(re)物(wu)(wu)體的(de)(de)(de)(de)(de)(de)材(cai)料。對于(yu)鐵的(de)(de)(de)(de)(de)(de)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)體，電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)可(ke)以(yi)(yi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)到(dao)(dao)500到(dao)(dao)600度(du)(du)(du)以(yi)(yi)上。如果功(gong)(gong)率(lv)(lv)不明顯，功(gong)(gong)率(lv)(lv)小(xiao)可(ke)以(yi)(yi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)到(dao)(dao)500度(du)(du)(du)以(yi)(yi)上，但功(gong)(gong)率(lv)(lv)大(da)時(shi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)速(su)(su)度(du)(du)(du)快，小(xiao)功(gong)(gong)率(lv)(lv)時(shi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)速(su)(su)度(du)(du)(du)慢。如果它(ta)(ta)是(shi)(shi)臺大(da)機器(qi)(qi)(qi)(qi)(qi)，它(ta)(ta)配(pei)備了(le)大(da)功(gong)(gong)率(lv)(lv)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)，如果它(ta)(ta)是(shi)(shi)臺小(xiao)型的(de)(de)(de)(de)(de)(de)機器(qi)(qi)(qi)(qi)(qi)，它(ta)(ta)就(jiu)配(pei)備了(le)低功(gong)(gong)率(lv)(lv)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)。因為加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)(de)(de)(de)(de)(de)速(su)(su)度(du)(du)(du)直接(jie)影響(xiang)到(dao)(dao)生產(chan)的(de)(de)(de)(de)(de)(de)過程和速(su)(su)度(du)(du)(du)，所以(yi)(yi)般情況下好有更(geng)高的(de)(de)(de)(de)(de)(de)功(gong)(gong)率(lv)(lv)，這(zhe)樣加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)(de)(de)(de)(de)(de)速(su)(su)度(du)(du)(du)就(jiu)會更(geng)快。為什么鐵不能(neng)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)到(dao)(dao)600度(du)(du)(du)呢？這(zhe)是(shi)(shi)因為鐵達(da)到(dao)(dao)600度(du)(du)(du)時(shi)達(da)到(dao)(dao)居里點，這(zhe)是(shi)(shi)退磁(ci)，當鐵丟失(shi)時(shi)，如果主機沒有保護電(dian)(dian)(dian)路，那是(shi)(shi)危(wei)險(xian)的(de)(de)(de)(de)(de)(de)。如果加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)(de)(de)(de)(de)(de)物(wu)(wu)體是(shi)(shi)石墨鋼罐，高溫(wen)度(du)(du)(du)可(ke)以(yi)(yi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)到(dao)(dao)1000度(du)(du)(du)以(yi)(yi)上。在同功(gong)(gong)率(lv)(lv)下，哪種電(dian)(dian)(dian)磁(ci)式(shi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)和傳統(tong)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)阻式(shi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)更(geng)快？這(zhe)對電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)來說更(geng)快，因為傳統(tong)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)阻式(shi)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)通(tong)常只有大(da)約(yue)60%的(de)(de)(de)(de)(de)(de)熱(re)(re)(re)(re)(re)效(xiao)率(lv)(lv)，而電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)熱(re)(re)(re)(re)(re)效(xiao)率(lv)(lv)利用率(lv)(lv)超過90%。加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)速(su)(su)度(du)(du)(du)自然是(shi)(shi)電(dian)(dian)(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)速(su)(su)度(du)(du)(du)更(geng)快。
