電磁加熱器的(de)使(shi)用壽命卻和以下幾個點有(you)著密不可分(fen)的(de)關系：

1、產品(pin)定要(yao)保(bao)證產品(pin)正(zheng)確的(de)(de)(de)安(an)(an)裝。每款電(dian)(dian)磁加(jia)熱(re)器及電(dian)(dian)磁加(jia)熱(re)圈所要(yao)求(qiu)的(de)(de)(de)保(bao)溫棉的(de)(de)(de)厚道，繞(rao)線的(de)(de)(de)粗(cu)細長度(du)，電(dian)(dian)感值(zhi)，輸(shu)入(ru)電(dian)(dian)流值(zhi)都是(shi)不同的(de)(de)(de)，要(yao)嚴格按照廠家出廠時(shi)安(an)(an)裝說明(ming)書為標準。

2、使(shi)用(yong)壽命與(yu)環(huan)境(jing)分不開關系，諸(zhu)如(ru)粉塵，灰塵，潮濕度等(deng)等(deng)因素。如(ru)果空(kong)氣中的(de)粉塵灰塵超過定比例，就會對電磁(ci)(ci)加熱(re)(re)控(kong)制主板(ban)造成較(jiao)大的(de)影響。使(shi)用(yong)者需(xu)要(yao)定期(qi)專門(men)企(qi)業清理維護(hu)電磁(ci)(ci)加熱(re)(re)器(qi)(qi)，室(shi)內的(de)通風要(yao)好，良好的(de)環(huan)境(jing)會大幅提升(sheng)電磁(ci)(ci)加熱(re)(re)器(qi)(qi)的(de)壽命。

3、不(bu)得不(bu)說的(de)是(shi)，使用(yong)壽命與產品的(de)質(zhi)量也(ye)分不(bu)開。機器(qi)所(suo)采用(yong)的(de)原器(qi)件，電路板設計(ji)合(he)理與否會(hui)導(dao)致終的(de)產品質(zhi)量會(hui)有(you)很(hen)大出(chu)入(ru)，如何(he)選擇專業的(de)電磁加熱器(qi)品是(shi)重中之重。

4、使(shi)用壽命與對(dui)產(chan)品的(de)愛護(hu)程度(du)關系(xi)也密不可分。個(ge)(ge)被好(hao)好(hao)愛護(hu)使(shi)用的(de)機(ji)器對(dui)要比個(ge)(ge)從不愛護(hu)保養(yang)的(de)機(ji)器壽命要長。

電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)對(dui)(dui)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)行業(ye)的(de)作用(yong)(yong)：當(dang)今世界使用(yong)(yong)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)的(de)途徑有三(san)種(zhong)：燃(ran)燒(shao)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)、電(dian)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)和(he)(he)其它能(neng)源(yuan)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)，當(dang)然(ran)前兩種(zhong)是(shi)如今主要，也(ye)是(shi)常用(yong)(yong)的(de)物(wu)料(liao)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)方式(shi)。但(dan)是(shi)電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)方式(shi)又比燃(ran)燒(shao)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)方式(shi)清潔衛(wei)生(sheng)(sheng)(sheng)、熱(re)(re)(re)(re)(re)效率高(gao)(可(ke)達85%-95%)、安全、可(ke)調節、系(xi)統簡便等(deng)(deng)優點。電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)應(ying)用(yong)(yong)域(yu)(yu)廣泛，大(da)(da)致可(ke)以分為民用(yong)(yong)和(he)(he)工(gong)業(ye)用(yong)(yong)兩種(zhong)應(ying)用(yong)(yong)域(yu)(yu)。民用(yong)(yong)域(yu)(yu)主要包括空(kong)調、洗衣機(ji)、熱(re)(re)(re)(re)(re)水器(qi)(qi)等(deng)(deng)大(da)(da)家(jia)電(dian)及豆漿機(ji)、飲(yin)水機(ji)等(deng)(deng)小家(jia)電(dian)，應(ying)用(yong)(yong)于(yu)民用(yong)(yong)域(yu)(yu)的(de)電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)往(wang)(wang)往(wang)(wang)是(shi)標準件(jian)，單位(wei)(wei)價值(zhi)相對(dui)(dui)較低(di)但(dan)批(pi)量(liang)較大(da)(da);工(gong)業(ye)用(yong)(yong)域(yu)(yu)主要包括多晶硅生(sheng)(sheng)(sheng)產、石(shi)油天然(ran)氣開采、石(shi)化化工(gong)等(deng)(deng)域(yu)(yu)，應(ying)用(yong)(yong)于(yu)工(gong)業(ye)域(yu)(yu)的(de)電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)往(wang)(wang)往(wang)(wang)是(shi)工(gong)業(ye)生(sheng)(sheng)(sheng)產系(xi)統的(de)部分，是(shi)非(fei)標準件(jian)，對(dui)(dui)性(xing)能(neng)要求高(gao)，單位(wei)(wei)價值(zhi)和(he)(he)利潤相對(dui)(dui)較高(gao)。電(dian)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)有使用(yong)(yong)電(dian)熱(re)(re)(re)(re)(re)絲(si)的(de)和(he)(he)電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)。電(dian)熱(re)(re)(re)(re)(re)絲(si)初裝成本低(di)，壽命(ming)短，維護(hu)麻煩，耗電(dian)量(liang)大(da)(da)。而(er)電(dian)磁(ci)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)器(qi)(qi)加(jia)(jia)(jia)(jia)(jia)熱(re)(re)(re)(re)(re)效率高(gao)，能(neng)節省大(da)(da)量(liang)的(de)電(dian)能(neng)，壽命(ming)長(chang)。

電(dian)磁(ci)加熱對比其他幾種加熱方式(shi)：

、燃(ran)(ran)燒(shao)(shao)(shao)式(shi)(shi)加熱(re)：顧名思義就是通過燃(ran)(ran)料燃(ran)(ran)燒(shao)(shao)(shao)來實現熱(re)量(liang)傳輸了(le)(le)，這是原(yuan)始(shi)的(de)加熱(re)方式(shi)(shi)，燃(ran)(ran)煤(mei)(mei)加熱(re)、燃(ran)(ran)氣(qi)加熱(re)、生物質燃(ran)(ran)燒(shao)(shao)(shao)加熱(re)等等是常(chang)見的(de)，其中(zhong)燃(ran)(ran)燒(shao)(shao)(shao)加熱(re)所造(zao)成(cheng)的(de)嚴重，所以出(chu)于對環(huan)保(bao)的(de)問題，許多地(di)區都(dou)實行了(le)(le)禁煤(mei)(mei)令。不管哪種燃(ran)(ran)燒(shao)(shao)(shao)發熱(re)方式(shi)(shi)，都(dou)會(hui)對空氣(qi)有(you)排放(fang)，氧化(hua)碳(tan)、灰塵、硫化(hua)氣(qi)體、殘(can)渣等等，而且熱(re)效率(lv)也(ye)非常(chang)低。

二、接觸式(shi)(shi)加(jia)(jia)熱：這種加(jia)(jia)熱方(fang)式(shi)(shi)普遍的是(shi)(shi)(shi)電阻絲、電熱棒(bang)的形式(shi)(shi)，加(jia)(jia)熱液體的時(shi)候是(shi)(shi)(shi)直接與(yu)液體接觸，這種加(jia)(jia)熱方(fang)式(shi)(shi)有局限性(xing)，就是(shi)(shi)(shi)加(jia)(jia)熱溫度般(ban)是(shi)(shi)(shi)300℃以下(xia)，加(jia)(jia)熱時(shi)間(jian)(jian)長(chang)了會產生污垢，時(shi)間(jian)(jian)長(chang)了就會形成(cheng)管(guan)(guan)道破裂(lie)問題，再有就是(shi)(shi)(shi)接觸式(shi)(shi)容易產生漏電觸電問題，對(dui)人(ren)身安全有危害，所以對(dui)電熱管(guan)(guan)的質量要求是(shi)(shi)(shi)的；另(ling)外(wai)電熱管(guan)(guan)的熱效雖然比燃煤燃氣的要高引(yin)動，但對(dui)外(wai)還是(shi)(shi)(shi)部分(fen)熱量散失在(zai)空氣中。

三、電磁(ci)感(gan)(gan)應加(jia)(jia)熱(re)：電磁(ci)加(jia)(jia)熱(re)器是(shi)(shi)屬(shu)于非接觸(chu)式(shi)(shi)加(jia)(jia)熱(re)方(fang)式(shi)(shi)，其應用(yong)的(de)(de)工作(zuo)原理(li)和電磁(ci)爐(lu)加(jia)(jia)熱(re)原理(li)樣(yang)，通過電磁(ci)感(gan)(gan)應技(ji)術(shu)，利(li)(li)用(yong)磁(ci)變(bian)，使得金屬(shu)料筒自(zi)身產(chan)(chan)生渦流(liu)，達到(dao)自(zi)身產(chan)(chan)生熱(re)量，從(cong)而(er)實現加(jia)(jia)熱(re)目的(de)(de)，這樣(yang)的(de)(de)技(ji)術(shu)原理(li)大程(cheng)序(xu)的(de)(de)實現了(le)(le)對(dui)(dui)熱(re)效的(de)(de)全部(bu)利(li)(li)用(yong)，熱(re)效率(lv)高(gao)(gao)能(neng)(neng)(neng)達到(dao)98%，是(shi)(shi)目前熱(re)利(li)(li)用(yong)高(gao)(gao)的(de)(de)加(jia)(jia)熱(re)方(fang)式(shi)(shi)之，非接觸(chu)式(shi)(shi)的(de)(de)加(jia)(jia)熱(re)方(fang)式(shi)(shi)對(dui)(dui)安(an)全問題方(fang)面得到(dao)了(le)(le)保(bao)障，而(er)且使用(yong)壽命長，后期維護簡(jian)便，成本低(di)，重要的(de)(de)是(shi)(shi)它能(neng)(neng)(neng)夠實現高(gao)(gao)溫加(jia)(jia)熱(re)，廣泛適(shi)應工業應用(yong)，屬(shu)于很好的(de)(de)節能(neng)(neng)(neng)方(fang)式(shi)(shi)。

電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)(qi)的(de)(de)高溫線(xian)能不(bu)能繞(rao)(rao)(rao)兩層？大家都知道電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)(qi)的(de)(de)組(zu)成(cheng)是(shi)(shi)由電(dian)(dian)磁(ci)(ci)加(jia)熱(re)控(kong)制器(qi)(qi)以及(ji)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)線(xian)圈(quan)兩個(ge)部分組(zu)合才(cai)是(shi)(shi)個(ge)加(jia)熱(re)系(xi)統，兩者之間(jian)缺不(bu)可(ke)。目(mu)前(qian)使用(yong)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)(qi)的(de)(de)客(ke)戶(hu)越來(lai)越多，很多客(ke)戶(hu)都是(shi)(shi)外地的(de)(de)，這些地區如(ru)果(guo)要(yao)(yao)上門(men)安(an)裝的(de)(de)話(hua)客(ke)戶(hu)所需(xu)要(yao)(yao)承擔(dan)(dan)的(de)(de)成(cheng)本就比(bi)(bi)較(jiao)高，所以很多客(ke)戶(hu)為了(le)節(jie)省這筆(bi)安(an)裝費用(yong)都選著自己來(lai)安(an)裝電(dian)(dian)磁(ci)(ci)加(jia)熱(re)系(xi)統。在(zai)安(an)裝的(de)(de)時(shi)候(hou)(hou)有客(ke)戶(hu)會疑惑(huo)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)線(xian)圈(quan)太(tai)多了(le)能不(bu)能繞(rao)(rao)(rao)兩層。安(an)裝電(dian)(dian)磁(ci)(ci)加(jia)熱(re)線(xian)圈(quan)的(de)(de)時(shi)候(hou)(hou)如(ru)果(guo)被加(jia)熱(re)體直徑或者長度比(bi)(bi)較(jiao)小，線(xian)圈(quan)又(you)太(tai)多了(le)，線(xian)圈(quan)繞(rao)(rao)(rao)少(shao)了(le)電(dian)(dian)感量達(da)不(bu)到(dao)就會工作不(bu)了(le)。這個(ge)時(shi)候(hou)(hou)是(shi)(shi)可(ke)以采取電(dian)(dian)磁(ci)(ci)加(jia)熱(re)線(xian)圈(quan)繞(rao)(rao)(rao)雙層的(de)(de)。線(xian)圈(quan)的(de)(de)電(dian)(dian)感要(yao)(yao)達(da)到(dao)80kw電(dian)(dian)磁(ci)(ci)加(jia)熱(re)控(kong)制器(qi)(qi)的(de)(de)合適(shi)值(zhi)(zhi)才(cai)行。也不(bu)要(yao)(yao)擔(dan)(dan)心繞(rao)(rao)(rao)雙層對電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)(qi)的(de)(de)壽命會不(bu)會有影響(xiang)，只要(yao)(yao)電(dian)(dian)感量值(zhi)(zhi)達(da)到(dao)合適(shi)值(zhi)(zhi)才(cai)真正的(de)(de)對控(kong)制器(qi)(qi)不(bu)會有損壞(huai)。

電磁(ci)加熱(re)控制(zhi)器怎么安(an)裝(zhuang)？

1、改造前先取下原設(she)備上面(mian)的電熱圈。

3、在(zai)料(liao)筒上(shang)包層(ceng)隔(ge)熱保溫(wen)材料(liao)，按照步驟2將料(liao)筒清(qing)潔干(gan)凈(jing)后，在(zai)料(liao)筒上(shang)包上(shang)層(ceng)隔(ge)熱保溫(wen)材料(liao)（石棉或者玻璃(li)纖維(wei)均可(ke)），可(ke)以先做區，區做好后，再做其它區，熟練且經驗豐富者可(ke)幾個加熱區起做 。

4、用(yong)高溫(wen)(wen)布(bu)(bu)將保溫(wen)(wen)材(cai)料(liao)(liao)包好，保溫(wen)(wen)材(cai)料(liao)(liao)的(de)厚度根據使用(yong)的(de)不(bu)同的(de)電(dian)磁(ci)加(jia)(jia)熱控制器的(de)要求(qiu)來配，保溫(wen)(wen)材(cai)料(liao)(liao)包好后，再(zai)用(yong)高溫(wen)(wen)布(bu)(bu)（纖維布(bu)(bu)）或者(zhe)電(dian)木板(ban)（環氧樹脂板(ban)）將保溫(wen)(wen)材(cai)料(liao)(liao)包緊起來，該步驟主要是確保料(liao)(liao)筒各處的(de)保溫(wen)(wen)材(cai)料(liao)(liao)厚度致，以保證電(dian)磁(ci)加(jia)(jia)熱的(de)磁(ci)場均。

5、纏繞高溫電纜，高溫電纜的規格(ge)與長度請根據各種(zhong)不同型號電磁加熱控制器(qi)的要(yao)求選(xuan)配(pei)，該步(bu)驟非常關(guan)鍵。

第二種(zhong):是(shi)臺設備(bei)使用(yong)多個(ge)電(dian)磁(ci)加熱(re)控(kong)制器分別控(kong)制多個(ge)線圈。現在(zai)例(li)如注(zhu)塑(su)機，拉絲機，吹膜機，擠出機等機械(xie)設備(bei)，料管(guan)加熱(re)部分都需要幾(ji)個(ge)不同溫(wen)(wen)度才能滿足生產，這時候就要使用(yong)到電(dian)磁(ci)加熱(re)器多溫(wen)(wen)區來控(kong)制。

第三種(zhong)：臺電磁(ci)加熱(re)控制器控制多組線圈比較(jiao)少用，因為如果主機旦出(chu)現故障(zhang)，整個(ge)幾個(ge)溫(wen)度(du)都(dou)將無法加熱(re)，影(ying)響正規生產，而且維護起(qi)來也是比較(jiao)麻(ma)煩的。

第四種：多個電(dian)磁加(jia)熱控(kong)(kong)制(zhi)(zhi)器分(fen)(fen)別控(kong)(kong)制(zhi)(zhi)獨立(li)線圈，這樣不但便(bian)(bian)于管理，而且加(jia)熱非常均勻，維護起來也是十分(fen)(fen)方便(bian)(bian)的。
