使用電磁加熱器時應注意的(de)問題:

1、不要(yao)將控制器(qi)安裝(zhuang)在潮濕的(de)環境(jing)中,防止水(shui)蒸汽(qi)進入電箱后,易在緣介質表面凝結,降低其(qi)緣性能(neng),造成漏電事故。

2、在(zai)使(shi)用電(dian)磁控(kong)制器時(shi),應先按說明(ming)書繞好線圈并檢查無誤后(hou)再(zai)接通電(dian)源。

3、在使(shi)用過程中,不要(yao)輕易拆除其(qi)接地(di)導線,因為接地(di)措施是防止觸(chu)電(dian)的后道保護措施。

4、要經常檢查產(chan)品的進風口及散(san)熱(re)風扇,防止進風口處堵(du)塞或散(san)熱(re)風扇卡(ka)死,避免因過熱(re)停機保(bao)護(hu)。

5、要定期清理散熱器,保證(zheng)產品通風良(liang)好。

6、在(zai)保養清洗前切斷控制器(qi)電(dian)源。清潔電(dian)磁感應(ying)加熱器(qi)的外(wai)殼時,應(ying)用(yong)干凈的抹布進(jin)行擦拭,嚴禁(jin)用(yong)噴射水流(liu)沖(chong)洗外(wai)殼及電(dian)器(qi)箱(xiang)部分(fen)。

此外(wai),挑(tiao)(tiao)選線(xian)圈(quan)時,還(huan)要考慮其線(xian)徑(jing),材質(zhi),耐溫耐壓(ya)性能(neng)等(deng)。這些也(ye)都(dou)是(shi)(shi)(shi)由其使用(yong)(yong)條件決(jue)定的(de)(de)。在(zai)實際選配(pei)過(guo)程(cheng)中,先要根據加(jia)熱(re)(re)(re)需求確定所(suo)需設(she)備(bei)(bei)功(gong)率(lv)(lv),然后就(jiu)可以知道(dao)其輸出電(dian)(dian)(dian)(dian)流值,進而確定線(xian)徑(jing)、材質(zhi),然后視現場(chang)的(de)(de)溫度(du)情況,散熱(re)(re)(re)情況等(deng)考慮其耐溫性能(neng)。如果(guo)挑(tiao)(tiao)選線(xian)圈(quan)時沒有(you)(you)考慮到這些因素,就(jiu)很容易出現設(she)備(bei)(bei)故(gu)障,例如線(xian)圈(quan)被(bei)燒壞(huai),加(jia)熱(re)(re)(re)效(xiao)率(lv)(lv)低下,線(xian)圈(quan)不耐用(yong)(yong)等(deng)問題。輕(qing)則影響(xiang)生產,重則造成(cheng)(cheng)人身事(shi)故(gu)。二(er)線(xian)圈(quan)繞(rao)(rao)制(zhi):表面(mian)看來,線(xian)圈(quan)繞(rao)(rao)制(zhi)這工作似乎是(shi)(shi)(shi)沒技術含量(liang)的(de)(de),不就(jiu)是(shi)(shi)(shi)把(ba)線(xian)材繞(rao)(rao)下組成(cheng)(cheng)個線(xian)圈(quan)嘛,這誰不會(hui)?但實際上并(bing)沒有(you)(you)那么簡(jian)單,線(xian)圈(quan)的(de)(de)繞(rao)(rao)制(zhi)需要考慮到疊加(jia)、干擾、散熱(re)(re)(re)、距(ju)離、感(gan)量(liang)匹配(pei)等(deng)因素。不同(tong)(tong)功(gong)率(lv)(lv)的(de)(de)電(dian)(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)器(qi)其所(suo)需要的(de)(de)線(xian)圈(quan)電(dian)(dian)(dian)(dian)感(gan)量(liang)是(shi)(shi)(shi)不樣的(de)(de),只有(you)(you)實際電(dian)(dian)(dian)(dian)感(gan)量(liang)和理(li)(li)論值直,才(cai)能(neng)保證電(dian)(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)器(qi)的(de)(de)功(gong)率(lv)(lv)大化(hua)。例如,臺30KW的(de)(de)電(dian)(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)器(qi),其理(li)(li)論電(dian)(dian)(dian)(dian)感(gan)量(liang)是(shi)(shi)(shi)240μH,線(xian)圈(quan)繞(rao)(rao)制(zhi)時,只有(you)(you)實際感(gan)量(liang)為240μH,其功(gong)率(lv)(lv)才(cai)有(you)(you)可能(neng)完全達到。如果(guo)實際感(gan)量(liang)是(shi)(shi)(shi)100μH、150μH、300μH、400μH,那其這臺設(she)備(bei)(bei)的(de)(de)實際使用(yong)(yong)功(gong)率(lv)(lv)可能(neng)就(jiu)只有(you)(you)20KW,15KW,甚至(zhi)根本啟動(dong)不了(le)。三適(shi)用(yong)(yong)見場(chang):電(dian)(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)器(qi)的(de)(de)廣(guang)泛應用(yong)(yong)性決(jue)定了(le)其現場(chang)使用(yong)(yong)情況的(de)(de)復(fu)雜。在(zai)電(dian)(dian)(dian)(dian)磁加(jia)熱(re)(re)(re)器(qi)眾多的(de)(de)使用(yong)(yong)域中,食(shi)品、塑料、化(hua)工、印(yin)刷、供暖、垃圾(ji)處理(li)(li),每個行(xing)業(ye)的(de)(de)應用(yong)(yong)場(chang)景都(dou)不同(tong)(tong),就(jiu)是(shi)(shi)(shi)同(tong)(tong)個行(xing)業(ye)中,每個客戶的(de)(de)使用(yong)(yong)現場(chang)也(ye)有(you)(you)很大的(de)(de)差別。所(suo)以,電(dian)(dian)(dian)(dian)磁線(xian)圈(quan)不具(ju)有(you)(you)普遍適(shi)用(yong)(yong)性,是(shi)(shi)(shi)種(zhong)不同(tong)(tong)使用(yong)(yong)場(chang)景有(you)(you)不同(tong)(tong)繞(rao)(rao)法的(de)(de)非標配(pei)件。

電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器對加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)行業(ye)的(de)(de)作用(yong)(yong)(yong):當今世界(jie)使用(yong)(yong)(yong)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)的(de)(de)途徑有三種(zhong):燃燒(shao)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)、電(dian)(dian)(dian)(dian)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)和(he)(he)其(qi)它能源加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re),當然前兩種(zhong)是(shi)如今主(zhu)要,也是(shi)常用(yong)(yong)(yong)的(de)(de)物料加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)方式(shi)。但(dan)是(shi)電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)方式(shi)又比燃燒(shao)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)方式(shi)清潔衛生、熱(re)(re)(re)(re)(re)(re)(re)(re)效率(lv)高(gao)(可達85%-95%)、安全、可調節(jie)、系統(tong)簡便等(deng)優點。電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器應(ying)用(yong)(yong)(yong)域廣泛(fan),大(da)(da)致可以分為民用(yong)(yong)(yong)和(he)(he)工(gong)業(ye)用(yong)(yong)(yong)兩種(zhong)應(ying)用(yong)(yong)(yong)域。民用(yong)(yong)(yong)域主(zhu)要包(bao)括空調、洗衣機、熱(re)(re)(re)(re)(re)(re)(re)(re)水器等(deng)大(da)(da)家電(dian)(dian)(dian)(dian)及豆漿機、飲水機等(deng)小家電(dian)(dian)(dian)(dian),應(ying)用(yong)(yong)(yong)于民用(yong)(yong)(yong)域的(de)(de)電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器往往是(shi)標(biao)準件(jian)(jian),單(dan)位(wei)價值(zhi)相對較低但(dan)批量較大(da)(da);工(gong)業(ye)用(yong)(yong)(yong)域主(zhu)要包(bao)括多晶(jing)硅生產、石油天然氣開采、石化(hua)(hua)化(hua)(hua)工(gong)等(deng)域,應(ying)用(yong)(yong)(yong)于工(gong)業(ye)域的(de)(de)電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器往往是(shi)工(gong)業(ye)生產系統(tong)的(de)(de)部分,是(shi)非標(biao)準件(jian)(jian),對性(xing)能要求(qiu)高(gao),單(dan)位(wei)價值(zhi)和(he)(he)利潤相對較高(gao)。電(dian)(dian)(dian)(dian)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)有使用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)(re)絲(si)的(de)(de)和(he)(he)電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)。電(dian)(dian)(dian)(dian)熱(re)(re)(re)(re)(re)(re)(re)(re)絲(si)初裝成本低,壽命短,維護麻煩,耗電(dian)(dian)(dian)(dian)量大(da)(da)。而電(dian)(dian)(dian)(dian)磁(ci)加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)器加(jia)熱(re)(re)(re)(re)(re)(re)(re)(re)效率(lv)高(gao),能節(jie)省大(da)(da)量的(de)(de)電(dian)(dian)(dian)(dian)能,壽命長。

上海擠出機電磁加熱器的散熱

電(dian)磁加熱器高(gao)(gao)(gao)溫(wen)線(xian)(xian)(xian)的選(xuan)(xuan)擇(ze)(ze):從高(gao)(gao)(gao)溫(wen)線(xian)(xian)(xian)的外(wai)包裝來看,高(gao)(gao)(gao)溫(wen)線(xian)(xian)(xian)般(ban)(ban)通過導體+纖編(bian)織+云(yun)母繞(rao)包+涂(tu)層的組合而成。但(dan)是(shi)根(gen)據需(xu)要(yao)的不同(tong),會(hui)再添加玻(bo)纖編(bian)織和(he)云(yun)母繞(rao)包,發生(sheng)意外(wai)的幾率就能(neng)大大的減少。導體需(xu)要(yao)根(gen)據現場的情況和(he)工作的情況選(xuan)(xuan)擇(ze)(ze)高(gao)(gao)(gao)溫(wen)線(xian)(xian)(xian)的材(cai)質(zhi)是(shi)否進行電(dian)鍍,并且(qie)規格(ge)也有所(suo)選(xuan)(xuan)擇(ze)(ze),根(gen)據現場安裝機械選(xuan)(xuan)擇(ze)(ze)0.1mm2-0.3mm2的線(xian)(xian)(xian)徑(jing),線(xian)(xian)(xian)徑(jing)越(yue)粗,相對來說再繞(rao)制高(gao)(gao)(gao)線(xian)(xian)(xian)時(shi)越(yue)容易固定(ding),但(dan)是(shi)不容易扭(niu)動;而線(xian)(xian)(xian)徑(jing)細的繞(rao)線(xian)(xian)(xian)比較松散,所(suo)以般(ban)(ban)是(shi)考慮繞(rao)制方便時(shi)采用。而玻(bo)纖編(bian)織主(zhu)要(yao)能(neng)起(qi)到防磨和(he)耐熱作用;云(yun)母是(shi)種高(gao)(gao)(gao)性能(neng)緣制品,具有優良的耐高(gao)(gao)(gao)溫(wen)性能(neng)和(he)耐燃燒性能(neng);涂(tu)層能(neng)夠在起(qi)到防腐,耐磨,隔熱,緣;所(suo)以在選(xuan)(xuan)擇(ze)(ze)時(shi)玻(bo)纖編(bian)織、云(yun)母和(he)涂(tu)層的質(zhi)量也很重要(yao)。

使(shi)用電磁加熱器時這幾點不可忽視:

1、電磁加(jia)熱(re)器主機的(de)安頓(dun)環境不能在-20℃以下,高也不能超過(guo)50℃,且(qie)要枯燥、通風。

2、接入電(dian)(dian)(dian)(dian)源前:清楚電(dian)(dian)(dian)(dian)器(qi)作業需要(yao)(yao)的(de)總電(dian)(dian)(dian)(dian)量(liang)和(he)供電(dian)(dian)(dian)(dian)變壓(ya)器(qi)的(de)總容(rong)量(liang),不能(neng)(neng)超過(guo)供電(dian)(dian)(dian)(dian)的(de)總容(rong)量(liang),也盡可(ke)能(neng)(neng)不要(yao)(yao)去糟蹋。別(bie)的(de)要(yao)(yao)辨(bian)明單相220v、三相380v電(dian)(dian)(dian)(dian)壓(ya),不能(neng)(neng)接錯。終要(yao)(yao)留意的(de)就是,當電(dian)(dian)(dian)(dian)網的(de)電(dian)(dian)(dian)(dian)壓(ya)在規則電(dian)(dian)(dian)(dian)壓(ya)規模的(de)上下(xia)10%起(qi)浮(fu)時,制止運用大(da)功率電(dian)(dian)(dian)(dian)磁加(jia)熱設備。

3、變頻電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)熱(re)(re)(re)器是(shi)怕水(shui)的,因而、總歸,電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)熱(re)(re)(re)器不能有(you)水(shui)進入,任何狀(zhuang)況下都要防(fang)止這狀(zhuang)況,水(shui)蒸汽、濕(shi)氣過重也不可,電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)熱(re)(re)(re)線也相同怕水(shui),切忌(ji)用濕(shi)潤的手去觸摸或是(shi)在電(dian)(dian)(dian)磁(ci)(ci)(ci)加(jia)(jia)熱(re)(re)(re)線上搭曬濕(shi)潤的衣物等(deng)等(deng)。

4、電(dian)磁加熱(re)器生產(chan)廠家印刷電(dian)路(lu)板(ban)周圍不(bu)能有塑料、乙(yi)(yi)烯(xi)基(ji)和聚苯乙(yi)(yi)烯(xi)泡沫塑料(抗靜(jing)電(dian)類(lei)型在外),靜(jing)電(dian)很可能會損壞(huai)這(zhe)些(xie)電(dian)路(lu)。不(bu)要觸摸操控(kong)接口板(ban)或操控(kong)板(ban)的IC電(dian)路(lu)。

5、電(dian)磁(ci)(ci)加熱線外表是石(shi)棉(mian)原料,怕磨(mo),因而電(dian)磁(ci)(ci)加熱線應防(fang)止轟動兇猛的(de)設備,防(fang)止磨(mo)損的(de)電(dian)磁(ci)(ci)加熱線呈(cheng)現漏(lou)電(dian)現象(xiang),觸(chu)摸(mo)接(jie)(jie)地(di)的(de)金屬(shu)物體(ti),用手觸(chu)摸(mo)這些操(cao)控(kong)器(qi)(qi)之(zhi)前消除身體(ti)上的(de)靜(jing)電(dian)(封(feng)閉操(cao)控(kong)器(qi)(qi)的(de)電(dian)源。并且在觸(chu)摸(mo)操(cao)控(kong)器(qi)(qi)時堅持接(jie)(jie)地(di))。

6、任(ren)何替換設備(bei)、檢修設備(bei)環節定要斷電(dian)今(jin)后才干(gan)進(jin)行,不要用手或導體觸(chu)摸印刷電(dian)路板上的元件或導體。

7、任(ren)何替換設備、檢修設備環節定要斷電今(jin)后才(cai)干進行。

電磁加熱器(qi)用(yong)于油氣管道應用(yong)的(de)特點(dian):

1、熱(re)效(xiao)高:節能電磁(ci)加熱(re)器不需要預熱(re)管道。

2、不破壞管道(dao)保溫層(ceng)(ceng):由于是感應節能電(dian)磁加熱,磁力(li)線能穿(chuan)透保溫層(ceng)(ceng),改造管單(dan)。

3、安全(quan)性高(gao):無(wu)明(ming)火(huo),無(wu)熱輻射(she),溫度(du)可控(kong)。

4、操作(zuo)方便:在管道上(shang)纏上(shang)電磁線圈(quan),做好溫(wen)(wen)度控溫(wen)(wen)探頭,調節控溫(wen)(wen)系(xi)統,開(kai)機調節即可自(zi)控加熱恒溫(wen)(wen)。

電磁感(gan)應加(jia)熱器使用過程中線圈溫度(du)過高原因:

1、電(dian)磁(ci)加熱器的(de)高溫(wen)電(dian)纜線徑(jing)(jing)小:不(bu)同功率(lv)的(de)電(dian)磁(ci)加熱控制器配(pei)備的(de)高溫(wen)電(dian)纜的(de)線徑(jing)(jing)不(bu)同,是(shi)因為(wei)所要輸送的(de)量不(bu)同,如果通道過窄(zhai),單(dan)位空間內承載的(de)量超過了它本身(shen)的(de)能力(li)的(de)話,散發(fa)的(de)熱量自然也(ye)就會比正常的(de)要高。

2、電(dian)磁加熱(re)控(kong)制器的(de)保溫(wen)(wen)(wen)棉薄:為了充分(fen)發揮保溫(wen)(wen)(wen)棉保溫(wen)(wen)(wen)、隔熱(re)的(de)效果,保溫(wen)(wen)(wen)棉的(de)厚度(du)通(tong)常在(zai)15-25mm左右,如果厚度(du)過小,料筒熱(re)量散失的(de)就(jiu)(jiu)多,那高(gao)溫(wen)(wen)(wen)線纜的(de)溫(wen)(wen)(wen)度(du)也就(jiu)(jiu)會高(gao);相(xiang)反,如果保溫(wen)(wen)(wen)棉厚度(du)過大(da)的(de)話,就(jiu)(jiu)會影響(xiang)高(gao)溫(wen)(wen)(wen)線纜的(de)電(dian)磁感應效果,造成電(dian)熱(re)轉換率低,影響(xiang)設(she)備的(de)工作效率。

3、電(dian)(dian)(dian)磁加熱(re)器的(de)線圈(quan)(quan)纏繞數少:電(dian)(dian)(dian)磁加熱(re)器表(biao)面線圈(quan)(quan)纏繞的(de)圈(quan)(quan)數與(yu)電(dian)(dian)(dian)感量大小(xiao)成正比,線圈(quan)(quan)小(xiao)的(de)話,電(dian)(dian)(dian)感量也就(jiu)小(xiao),那(nei)么電(dian)(dian)(dian)磁加熱(re)控制器就(jiu)要輸出更(geng)多的(de)電(dian)(dian)(dian)流才能達(da)到加熱(re)的(de)效果,高溫(wen)電(dian)(dian)(dian)纜承(cheng)載的(de)量就(jiu)會多,散發(fa)的(de)熱(re)量也就(jiu)高。

影響(xiang)電磁加(jia)熱器質量好壞(huai)的幾個原因:

1、材料(liao)因素——電(dian)磁加熱(re)器(qi)因為(wei)(wei)是(shi)(shi)工(gong)業產品,所以元器(qi)件(jian)(jian)的(de)選材上(shang),追(zhui)求的(de)是(shi)(shi)持續、穩定的(de)元器(qi)件(jian)(jian),好的(de)電(dian)磁加熱(re)器(qi)價(jia)(jia)格上(shang)對高于,小廠所謂的(de)普及品,流(liu)工(gong)廠做質量(liang),二流(liu)工(gong)廠做價(jia)(jia)格。說簡(jian)單(dan)點大(da)(da)廠為(wei)(wei)了質量(liang),選配元器(qi)件(jian)(jian)上(shang)喜歡采用(yong)進口(kou)的(de)好元器(qi)件(jian)(jian),個別(bie)時(shi)候可能因為(wei)(wei)讓(rang)設備更長壽,采用(yong)遠超需要(yao)的(de)元器(qi)件(jian)(jian),不讓(rang)元器(qi)件(jian)(jian)滿負荷工(gong)作(zuo),而小公司為(wei)(wei)了多賣機器(qi),大(da)(da)多打(da)著便(bian)宜(yi)的(de)口(kou)號,但便(bian)宜(yi)的(de)價(jia)(jia)格來至于低廉(lian)的(de)成本,低成本必(bi)然是(shi)(shi)低質量(liang)。

2、技術因素——電視機(ji)(ji)這個成熟的(de)產品(pin)(pin)不(bu)同的(de)品(pin)(pin)還(huan)有(you)著好壞之分,何況是電磁(ci)加(jia)熱(re)這個新興產業(ye),有(you)的(de)廠家開廠好幾(ji)年(nian)了,有(you)的(de)廠家才兩年(nian),如果說技術條件是樣的(de),那(nei)是不(bu)可能(neng)的(de),期(qi)間每個型號的(de)機(ji)(ji)器都有(you)技術性的(de)改動,改動多的(de)2.5kw的(de)電磁(ci)加(jia)熱(re)器超過四次重新設(she)計了,期(qi)間些小缺(que)陷慢慢的(de)也修補完善,如果家新公司在沒有(you)產品(pin)(pin)大量(liang)市(shi)場反饋,單(dan)憑技術人員實驗是不(bu)可能(neng)做出(chu)合(he)適的(de)電磁(ci)加(jia)熱(re)器的(de),因為(wei)他們只(zhi)懂(dong)電磁(ci)加(jia)熱(re)器不(bu)懂(dong)塑(su)料(liao)生(sheng)產,不(bu)懂(dong)塑(su)料(liao)機(ji)(ji)的(de)原理。

3、經驗因素(su)——電(dian)磁加熱(re)器(qi)(qi)(qi)安裝的(de)好(hao),和安裝的(de)不好(hao)效果是很打(da)區別(bie),這(zhe)(zhe)點需要豐(feng)富的(de)安裝實例(li),光靠幾(ji)組數據(ju)(ju)是分析不出來(lai)的(de),新公司根(gen)本沒有這(zhe)(zhe)樣(yang)的(de)經驗來(lai)支撐,完全靠理(li)論(lun)在安裝。人家(jia)說(shuo)臺同型號的(de)電(dian)磁加熱(re)器(qi)(qi)(qi),裝在同型號的(de)注(zhu)塑機上,為什么個省(sheng)電(dian)40%以上,個剛剛夠(gou)理(li)論(lun)數據(ju)(ju)的(de)30%,電(dian)磁感應加熱(re)器(qi)(qi)(qi)講解這(zhe)(zhe)不僅是機器(qi)(qi)(qi)的(de)差異(yi),電(dian)磁加熱(re)器(qi)(qi)(qi)的(de)安裝位置(zhi),線(xian)圈長短都有影(ying)響,如果是采(cai)用多組小(xiao)功(gong)率(lv)的(de)電(dian)磁加熱(re)器(qi)(qi)(qi),這(zhe)(zhe)個差異(yi)就更(geng)為明顯。
