電磁(ci)加熱器日常(chang)護理:

1、產(chan)品是(shi)否(fou)正確(que)安(an)裝(zhuang) 。每款電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)及(ji)(ji)電(dian)(dian)磁(ci)(ci)加(jia)熱(re)圈所要(yao)求的保(bao)溫棉的厚道,繞線(xian)的粗細長度,電(dian)(dian)感(gan)值(zhi),輸入電(dian)(dian)流(liu)值(zhi)都是(shi)不同的,定(ding)要(yao)按照廠家出廠時安(an)裝(zhuang)說明書為標準。以(yi)及(ji)(ji)每臺電(dian)(dian)磁(ci)(ci)加(jia)熱(re)控制板之(zhi)間(jian)的線(xian)圈組(zu)間(jian)隔間(jian)距在(zai)10cm以(yi)上也(ye)是(shi)非常重要(yao)的,因為靠(kao)的太近會相互影響。只有電(dian)(dian)磁(ci)(ci)加(jia)熱(re)器(qi)安(an)裝(zhuang)在(zai)正常參數范圍內才能保(bao)證的長期(qi)穩(wen)定(ding)工作。

2、車間的環境包括(kuo)粉塵(chen),灰(hui)塵(chen),潮(chao)濕度有關。般(ban)來講(jiang)粉塵(chen)灰(hui)塵(chen)越大,對電(dian)磁加熱控制主(zhu)板越不利。如果是(shi)粉塵(chen)灰(hui)塵(chen)比(bi)較(jiao)大的情況下,需要定期(qi)清理(li)電(dian)磁加熱器(qi)上的風扇,風冷電(dian)磁加熱器(qi)主(zhu)要是(shi)散熱,室內通風要好,避免(mian)風扇被卡住(zhu)而起不到主(zhu)板散熱效果從而使得元器(qi)件過(guo)熱而燒壞。

3、產品(pin)的(de)質量(liang)(liang)也有很大關系。如果是(shi)(shi)已(yi)經按說明書上的(de)參數來安裝,車間粉塵灰塵也不大的(de)情況下(xia)電(dian)磁加熱器還(huan)是(shi)(shi)經常出(chu)故障(zhang),那么這就是(shi)(shi)質量(liang)(liang)方面的(de)問(wen)題(ti)了(le)(le)。不排除有的(de)廠家為(wei)了(le)(le)降低成本而(er)采(cai)用便(bian)宜的(de)元器件(jian)來做導致產品(pin)質量(liang)(liang)不穩定而(er)經常出(chu)現故障(zhang),另外個原(yuan)因就是(shi)(shi)雖然(ran)用的(de)元器件(jian)是(shi)(shi)好的(de),但本身電(dian)路板設(she)計(ji)不合理也會導致易(yi)出(chu)現故障(zhang)。如果是(shi)(shi)質量(liang)(liang)問(wen)題(ti)導致的(de),建議可以換家了(le)(le)。

4、對產品的(de)(de)愛護程度。對于車間(jian)灰塵(chen)粉塵(chen)比較大的(de)(de)用(yong)戶(hu),應(ying)該定期用(yong)毛刷刷下電(dian)(dian)(dian)磁加熱(re)器(qi)上的(de)(de)風扇,與電(dian)(dian)(dian)磁加熱(re)線(xian)圈(quan)上的(de)(de)粉塵(chen),對于線(xian)圈(quan)不用(yong)有重(zhong)物壓(ya)住,或(huo)割破,不要經(jing)常有水濺到線(xian)圈(quan)上或(huo)電(dian)(dian)(dian)磁感應(ying)加熱(re)器(qi)上。更不要將(jiang)電(dian)(dian)(dian)磁加熱(re)器(qi)暴露(lu)在露(lu)天(tian)環(huan)境下,因為露(lu)天(tian)環(huan)境如果遇到下雨(yu)天(tian)肯(ken)定就(jiu)要淋濕,在未(wei)干的(de)(de)情(qing)況(kuang)下開機(ji)就(jiu)會導致(zhi)壞掉(diao)。或(huo)者露(lu)天(tian)環(huan)境早晨(chen)雨(yu)露(lu)較多,導致(zhi)電(dian)(dian)(dian)路板潮濕,未(wei)干的(de)(de)情(qing)況(kuang)下開機(ji)也會導致(zhi)里面的(de)(de)線(xian)路短路。

黑龍江15kw電磁加熱器選型

電(dian)磁加(jia)熱器(qi)高溫(wen)線(xian)(xian)的(de)(de)(de)選擇:從高溫(wen)線(xian)(xian)的(de)(de)(de)外包(bao)裝來看,高溫(wen)線(xian)(xian)般通過導(dao)體+纖編(bian)織+云(yun)母繞(rao)包(bao)+涂層(ceng)的(de)(de)(de)組合而(er)成。但是根(gen)(gen)(gen)據(ju)需要的(de)(de)(de)不(bu)同,會(hui)再添加(jia)玻纖編(bian)織和(he)云(yun)母繞(rao)包(bao),發生意外的(de)(de)(de)幾率就(jiu)能(neng)大(da)大(da)的(de)(de)(de)減少。導(dao)體需要根(gen)(gen)(gen)據(ju)現場(chang)的(de)(de)(de)情(qing)(qing)況和(he)工作的(de)(de)(de)情(qing)(qing)況選擇高溫(wen)線(xian)(xian)的(de)(de)(de)材(cai)質是否(fou)進行電(dian)鍍(du),并且規格也有(you)所選擇,根(gen)(gen)(gen)據(ju)現場(chang)安裝機械選擇0.1mm2-0.3mm2的(de)(de)(de)線(xian)(xian)徑,線(xian)(xian)徑越(yue)粗(cu),相(xiang)對來說再繞(rao)制高線(xian)(xian)時(shi)越(yue)容(rong)易固定,但是不(bu)容(rong)易扭動(dong);而(er)線(xian)(xian)徑細的(de)(de)(de)繞(rao)線(xian)(xian)比較松散(san),所以般是考慮繞(rao)制方便時(shi)采(cai)用。而(er)玻纖編(bian)織主要能(neng)起(qi)到防磨和(he)耐熱作用;云(yun)母是種高性能(neng)緣(yuan)制品,具(ju)有(you)優良的(de)(de)(de)耐高溫(wen)性能(neng)和(he)耐燃燒性能(neng);涂層(ceng)能(neng)夠在起(qi)到防腐(fu),耐磨,隔熱,緣(yuan);所以在選擇時(shi)玻纖編(bian)織、云(yun)母和(he)涂層(ceng)的(de)(de)(de)質量也很重要。

如何選擇電磁加(jia)熱器保溫材料?

1、根據材料的耐(nai)溫(wen)等,選(xuan)擇(ze)耐(nai)溫(wen)比發熱(re)(re)體(ti)表面的加熱(re)(re)溫(wen)度高至少300度的保(bao)溫(wen)材料。

2、根(gen)據電磁加熱控制器(qi)線(xian)圈布置的面積以(yi)及線(xian)圈與發熱體的距離(li),選(xuan)擇合適導熱系數的保溫材(cai)料(liao)。

3、根據線圈成型要求,選擇不同致密性和(he)硬度的保溫材(cai)料。

4、根據現場的施工條件,選擇適(shi)合的保溫材料(liao)。

5、重要(yao)的條原則,就是要(yao)保證經過上述選擇后,保溫(wen)棉表(biao)面的溫(wen)度在(zai)(zai)工作過程(cheng)中,盡可能低。高溫(wen)場合至少要(yao)保持在(zai)(zai)100度以下。

 電磁加(jia)熱(re)器(qi)普通加(jia)熱(re)圈加(jia)熱(re)方式優勢:

1、接(jie)觸式熱傳遞(di)加(jia)熱。

2、耗電的 30-70% 轉化為工(gong)作熱(re)能。

3、加熱通過接觸(chu)方(fang)式傳遞熱能。

4、加熱及(ji)冷卻都(dou)有慣(guan)性現象產(chan)生(sheng),及(ji)升溫降溫都(dou)緩慢。

5、加熱(re)有死角,不能完全(quan)包裹在料筒外層。

6、加熱圈損(sun)耗大(da),壽命(ming)短。

電磁加熱功率(lv)選配:、確認需(xu)要節能(neng)改造(zao)的設備原來的加熱形(xing)式(shi):

1、電爐(lu)絲(si)/石英:確(que)認原來加(jia)(jia)熱(re)區(qu)數量、每個溫區(qu)的(de)加(jia)(jia)熱(re)功率(lv)(lv),就近選(xuan)擇相應功率(lv)(lv)型號的(de)電磁(ci)加(jia)(jia)熱(re)產品進(jin)行搭配(pei)即可(ke),功率(lv)(lv)如果小(xiao)于(yu)2.5KW則律選(xuan)擇2.5KW電磁(ci)加(jia)(jia)熱(re)控(kong)制板,搭配(pei)產品的(de)數量與(yu)原來加(jia)(jia)熱(re)區(qu)樣的(de)數量即可(ke),該方法主要用(yong)于(yu)注(zhu)塑(su)機(ji)(ji)、吹膜機(ji)(ji)、拉絲(si)機(ji)(ji)、擠出機(ji)(ji)等功率(lv)(lv)較小(xiao)的(de)設備。

2、燒煤(mei)/柴油加(jia)(jia)熱(re)(re):確認料筒(tong)直徑、需(xu)(xu)加(jia)(jia)熱(re)(re)區域的(de)(de)長度、根據生產需(xu)(xu)要加(jia)(jia)熱(re)(re)的(de)(de)溫度、具體(ti)的(de)(de)產量(liang)要求,該方法需(xu)(xu)要定(ding)的(de)(de)專業水(shui)平與經驗,客戶(hu)如(ru)若有(you)需(xu)(xu)要可(ke)以提供以上數據由電磁加(jia)(jia)熱(re)(re)器的(de)(de)廠家進(jin)行(xing)鑒定(ding)。該方法主要用(yong)于水(shui)料造粒機、各(ge)種鍋爐等較大功(gong)率的(de)(de)設備。

二(er)、采暖器:電磁加熱采暖的功率搭(da)配可(ke)參考日常空調的搭(da)配方(fang)法,即15平(ping)方(fang)/KW即可(ke)滿足采暖需求。

三、將放置于水中加熱的電熱棒改造成同(tong)等(deng)功率的電磁感應加熱器其(qi)(qi)節電效果在10%以(yi)內(nei),不太顯著(zhu),但可以(yi)大大提(ti)高其(qi)(qi)安全性及抗氧化(hua)能(neng)力。

電磁(ci)加熱器(qi)注意事項(xiang):

1、主機要定(ding)期除(chu)塵,般(ban)1個(ge)月除(chu)次,可用軟毛刷或(huo)高壓氣槍除(chu)塵,以保證(zheng)儀器內部(bu)良(liang)好的通(tong)風環境。

2、如使(shi)用環境是帶有腐(fu)蝕性氣體的(de)(de)地(di)方(fang)須(xu)噴上緣清漆。或者用其(qi)它的(de)(de)緣防腐(fu)材(cai)料。

3、空氣(qi)溫度(du)不能(neng)高(gao)于50℃。

4、電(dian)感量只是應用的其中個參數而已,具體要(yao)實測(ce)工作(zuo)頻率和電(dian)流(liu),通過(guo)增減線圈匝數來匹配功率。
