此外(wai),挑選線(xian)(xian)(xian)圈(quan)(quan)(quan)時(shi),還要(yao)考(kao)慮(lv)其(qi)線(xian)(xian)(xian)徑(jing),材(cai)質,耐(nai)溫耐(nai)壓性能等(deng)(deng)。這(zhe)些也都是(shi)(shi)由(you)其(qi)使用(yong)(yong)(yong)條件(jian)決(jue)(jue)定的(de)。在實(shi)際(ji)選配過程中(zhong)(zhong),先要(yao)根據加(jia)(jia)熱(re)(re)(re)(re)需求確定所需設備功(gong)率(lv),然(ran)后(hou)就(jiu)可(ke)(ke)以(yi)知道其(qi)輸出(chu)電(dian)(dian)(dian)流(liu)值(zhi),進而確定線(xian)(xian)(xian)徑(jing)、材(cai)質,然(ran)后(hou)視現(xian)場(chang)(chang)的(de)溫度情(qing)(qing)況(kuang),散熱(re)(re)(re)(re)情(qing)(qing)況(kuang)等(deng)(deng)考(kao)慮(lv)其(qi)耐(nai)溫性能。如(ru)果挑選線(xian)(xian)(xian)圈(quan)(quan)(quan)時(shi)沒(mei)有(you)(you)(you)考(kao)慮(lv)到(dao)這(zhe)些因(yin)素,就(jiu)很容(rong)易出(chu)現(xian)設備故障,例如(ru)線(xian)(xian)(xian)圈(quan)(quan)(quan)被燒(shao)壞,加(jia)(jia)熱(re)(re)(re)(re)效率(lv)低下,線(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)耐(nai)用(yong)(yong)(yong)等(deng)(deng)問題。輕則影響(xiang)生產,重(zhong)則造成(cheng)人身事(shi)故。二線(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)制:表面看來,線(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)制這(zhe)工作似乎是(shi)(shi)沒(mei)技術含(han)量(liang)(liang)(liang)的(de),不(bu)(bu)(bu)就(jiu)是(shi)(shi)把(ba)線(xian)(xian)(xian)材(cai)繞(rao)下組成(cheng)個(ge)線(xian)(xian)(xian)圈(quan)(quan)(quan)嘛,這(zhe)誰不(bu)(bu)(bu)會?但實(shi)際(ji)上并沒(mei)有(you)(you)(you)那么簡單,線(xian)(xian)(xian)圈(quan)(quan)(quan)的(de)繞(rao)制需要(yao)考(kao)慮(lv)到(dao)疊加(jia)(jia)、干擾、散熱(re)(re)(re)(re)、距離、感(gan)量(liang)(liang)(liang)匹配等(deng)(deng)因(yin)素。不(bu)(bu)(bu)同(tong)(tong)功(gong)率(lv)的(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)(re)器(qi)其(qi)所需要(yao)的(de)線(xian)(xian)(xian)圈(quan)(quan)(quan)電(dian)(dian)(dian)感(gan)量(liang)(liang)(liang)是(shi)(shi)不(bu)(bu)(bu)樣(yang)的(de),只有(you)(you)(you)實(shi)際(ji)電(dian)(dian)(dian)感(gan)量(liang)(liang)(liang)和理論值(zhi)直,才能保證電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)(re)器(qi)的(de)功(gong)率(lv)大化(hua)。例如(ru),臺30KW的(de)電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)(re)器(qi),其(qi)理論電(dian)(dian)(dian)感(gan)量(liang)(liang)(liang)是(shi)(shi)240μH,線(xian)(xian)(xian)圈(quan)(quan)(quan)繞(rao)制時(shi),只有(you)(you)(you)實(shi)際(ji)感(gan)量(liang)(liang)(liang)為240μH,其(qi)功(gong)率(lv)才有(you)(you)(you)可(ke)(ke)能完全達(da)到(dao)。如(ru)果實(shi)際(ji)感(gan)量(liang)(liang)(liang)是(shi)(shi)100μH、150μH、300μH、400μH,那其(qi)這(zhe)臺設備的(de)實(shi)際(ji)使用(yong)(yong)(yong)功(gong)率(lv)可(ke)(ke)能就(jiu)只有(you)(you)(you)20KW,15KW,甚至根本(ben)啟動不(bu)(bu)(bu)了(le)。三適(shi)用(yong)(yong)(yong)見場(chang)(chang):電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)(re)器(qi)的(de)廣(guang)泛應用(yong)(yong)(yong)性決(jue)(jue)定了(le)其(qi)現(xian)場(chang)(chang)使用(yong)(yong)(yong)情(qing)(qing)況(kuang)的(de)復雜。在電(dian)(dian)(dian)磁(ci)(ci)加(jia)(jia)熱(re)(re)(re)(re)器(qi)眾多的(de)使用(yong)(yong)(yong)域中(zhong)(zhong),食品、塑料、化(hua)工、印刷、供暖、垃圾處理,每(mei)個(ge)行業的(de)應用(yong)(yong)(yong)場(chang)(chang)景都不(bu)(bu)(bu)同(tong)(tong),就(jiu)是(shi)(shi)同(tong)(tong)個(ge)行業中(zhong)(zhong),每(mei)個(ge)客戶的(de)使用(yong)(yong)(yong)現(xian)場(chang)(chang)也有(you)(you)(you)很大的(de)差別。所以(yi),電(dian)(dian)(dian)磁(ci)(ci)線(xian)(xian)(xian)圈(quan)(quan)(quan)不(bu)(bu)(bu)具有(you)(you)(you)普遍(bian)適(shi)用(yong)(yong)(yong)性,是(shi)(shi)種不(bu)(bu)(bu)同(tong)(tong)使用(yong)(yong)(yong)場(chang)(chang)景有(you)(you)(you)不(bu)(bu)(bu)同(tong)(tong)繞(rao)法的(de)非標配件(jian)。

電磁加(jia)(jia)熱(re)器在油田管道(dao)中(zhong)的應用:冬季由于野外(wai)氣溫(wen)較(jiao)低,在油由管道(dao)中(zhong)石(shi)油中(zhong)含蠟量高,管件(jian)容易(yi)(yi)凍堵。傳(chuan)統的方式(shi)(shi)是(shi)用火(huo)燒,但是(shi)用明火(huo)違反了采油區禁(jin)止明火(huo)的安全規定,易(yi)(yi)發生安全事故,電熱(re)發熱(re)板加(jia)(jia)熱(re)又(you)破壞了原有的保溫(wen)層(ceng),且熱(re)量散(san)失大,速度漫,時間(jian)長,功耗大。用錯能(neng)電磁加(jia)(jia)熱(re)器,機(ji)組(zu)磁力可以穿過保溫(wen)層(ceng)、纖(xian)維布等保溫(wen)材料以感應的方式(shi)(shi)快速對管道(dao)自(zi)身加(jia)(jia)熱(re)。

電(dian)磁加(jia)熱(re)器操作步(bu)驟簡介:

1、顯示界(jie)面:手(shou)動操作的(de)情況(kuang):啟(qi)(qi)(qi)動時(shi):先啟(qi)(qi)(qi)動水泵,再啟(qi)(qi)(qi)動加熱;停止時(shi):停止加熱,再停止水泵。

2、操(cao)作(zuo)畫面:自動(dong)和手動(dong)兩個模式(shi),可(ke)以根(gen)據(ju)實(shi)際情況(kuang)切換;6個溫(wen)度區可(ke)以根(gen)據(ju)實(shi)際情況(kuang)設定溫(wen)度。當前值(zhi)為(wei)傳(chuan)感器(qi)側出的實(shi)時值(zhi)。

3、運行設(she)(she)置(zhi):此(ci)界(jie)(jie)面(mian)(mian)是(shi)在自動模式下的工作(zuo)狀態。每(mei)周7天,每(mei)天4個(ge)時(shi)間(jian)段,根據實際情(qing)況設(she)(she)定(設(she)(she)置(zhi)此(ci)界(jie)(jie)面(mian)(mian),運行界(jie)(jie)面(mian)(mian)需調為手動模式)。

4、電磁加(jia)熱器(qi):該界面可(ke)“運行”和“停止”電磁加(jia)熱器(qi),同(tong)時(shi)可(ke)以觀(guan)(guan)察(cha)加(jia)熱器(qi)的實時(shi)參(can)數6曲線。該界面主要觀(guan)(guan)察(cha)6個(ge)溫度(du)的曲線圖,同(tong)時(shi)也可(ke)以插上(shang)U盤導出各個(ge)溫度(du)段的參(can)數,放于電腦上(shang)打印或是觀(guan)(guan)看。

5、儀表(biao)配(pei)置:主要是(shi)觀(guan)看(kan)本屏(ping)的些(xie)數據(ju),未(wei)經設(she)備廠的協助(zhu)下不(bu)可隨意更改參數。

電磁加(jia)熱板的(de)配件有哪些?2P排(pai)線、10K熱敏電阻、吸收板1塊、風扇線、顯(xian)示盒、530V電源線(帶磁環)、高頻(pin)互感器。

電磁加熱器的質(zhi)量是由(you)什(shen)么決(jue)定呢:

、重(zhong)要(yao)元器(qi)件的(de)選擇。電磁加熱控制(zhi)器(qi)功率(lv)部分核心元器(qi)件是IGBT模塊(kuai),IGBT的(de)優劣直(zhi)接影響到(dao)機器(qi)壽命長短,建議直(zhi)接從(cong)國內(nei)代理商那進貨,否則(ze)買到(dao)高仿或者翻(fan)新的(de)IGBT模塊(kuai)仍(reng)然會出現質量問題。

二、主板(ban)(ban)(ban)(ban)的(de)(de)(de)選擇。電(dian)(dian)(dian)磁加(jia)(jia)熱控制器(qi)的(de)(de)(de)主板(ban)(ban)(ban)(ban)分為三部分,電(dian)(dian)(dian)源(yuan)板(ban)(ban)(ban)(ban)、信號板(ban)(ban)(ban)(ban)和(he)驅動(dong)板(ban)(ban)(ban)(ban),要(yao)想保證(zheng)機(ji)器(qi)長時間穩定工(gong)作,主板(ban)(ban)(ban)(ban)要(yao)有各種保護:過(guo)載、過(guo)流(liu)和(he)過(guo)熱,電(dian)(dian)(dian)磁加(jia)(jia)熱器(qi)應用(yong)現(xian)(xian)場(chang)環境很(hen)復雜,比如干擾(rao)等(deng),旦出現(xian)(xian)非正常情況,主板(ban)(ban)(ban)(ban)應該能(neng)很(hen)快反應并保護機(ji)器(qi),防止非正常因素損壞機(ji)器(qi),特別(bie)是(shi)IGBT。目前市場(chang)上很(hen)多所(suo)謂(wei)的(de)(de)(de)電(dian)(dian)(dian)磁加(jia)(jia)熱器(qi)廠家的(de)(de)(de)主板(ban)(ban)(ban)(ban)并不是(shi)自己開發的(de)(de)(de),而是(shi)直(zhi)接購買的(de)(de)(de),然后自己組裝的(de)(de)(de),般出現(xian)(xian)問題(ti),就直(zhi)接讓客(ke)戶換主板(ban)(ban)(ban)(ban),并不能(neng)發現(xian)(xian)問題(ti)的(de)(de)(de)根源(yuan)所(suo)在。

三(san)、高(gao)溫線(xian)的(de)(de)選(xuan)擇。高(gao)溫線(xian)是(shi)(shi)(shi)(shi)(shi)(shi)很多(duo)客戶容易忽視的(de)(de)個(ge)(ge)問題,目(mu)前(qian)市場上國標(biao)(biao)的(de)(de)高(gao)溫線(xian)很難買到,不(bu)要(yao)(yao)相(xiang)信(xin)商家的(de)(de)所說的(de)(de),定睜大(da)眼睛,不(bu)要(yao)(yao)嫌(xian)麻煩,從重(zhong)量和(he)材質上鑒定下(xia)是(shi)(shi)(shi)(shi)(shi)(shi)否是(shi)(shi)(shi)(shi)(shi)(shi)國標(biao)(biao)高(gao)溫線(xian),如(ru)果(guo)用到非標(biao)(biao)高(gao)溫線(xian),不(bu)僅(jin)僅(jin)影響(xiang)機(ji)(ji)器(qi)壽命,還會(hui)影響(xiang)整機(ji)(ji)的(de)(de)效率,大(da)家應該重(zhong)視這(zhe)個(ge)(ge)問題。四經驗的(de)(de)差別。電(dian)磁加(jia)(jia)熱器(qi)安(an)裝(zhuang)的(de)(de)好,和(he)安(an)裝(zhuang)的(de)(de)不(bu)好效果(guo)是(shi)(shi)(shi)(shi)(shi)(shi)很大(da)區別,這(zhe)點需要(yao)(yao)豐富的(de)(de)安(an)裝(zhuang)實例,光靠(kao)幾組(zu)(zu)數據(ju)是(shi)(shi)(shi)(shi)(shi)(shi)分(fen)(fen)析不(bu)出來(lai)的(de)(de),根(gen)本沒有這(zhe)樣的(de)(de)經驗來(lai)支撐,完全(quan)靠(kao)理(li)(li)論在(zai)安(an)裝(zhuang)。人家說臺同(tong)型(xing)號的(de)(de)電(dian)磁加(jia)(jia)熱器(qi),裝(zhuang)在(zai)同(tong)型(xing)號的(de)(de)注塑(su)機(ji)(ji)上,為什么個(ge)(ge)省電(dian)40%以上,個(ge)(ge)剛剛夠理(li)(li)論數據(ju)的(de)(de)30%,這(zhe)個(ge)(ge)不(bu)僅(jin)是(shi)(shi)(shi)(shi)(shi)(shi)機(ji)(ji)器(qi)的(de)(de)差異(yi),電(dian)磁加(jia)(jia)熱器(qi)的(de)(de)安(an)裝(zhuang)位置,線(xian)圈長短都有影響(xiang),如(ru)果(guo)是(shi)(shi)(shi)(shi)(shi)(shi)采用多(duo)組(zu)(zu)小功率的(de)(de)電(dian)磁加(jia)(jia)熱器(qi),這(zhe)個(ge)(ge)差異(yi)就更為明顯。電(dian)磁加(jia)(jia)熱行業(ye)有個(ge)(ge)測試(shi)機(ji)(ji)器(qi)是(shi)(shi)(shi)(shi)(shi)(shi)否裝(zhuang)好的(de)(de)方(fang)法,就是(shi)(shi)(shi)(shi)(shi)(shi)讓電(dian)磁加(jia)(jia)熱器(qi)工作2分(fen)(fen)鐘左(zuo)右(you),休息1分(fen)(fen)鐘左(zuo)右(you)。

哪些因(yin)素會導致電磁加熱器發(fa)生故障?

:電(dian)(dian)(dian)磁(ci)加(jia)熱器電(dian)(dian)(dian)路設(she)計不科(ke)學。目(mu)前(qian),在(zai)大(da)(da)功(gong)率電(dian)(dian)(dian)磁(ci)加(jia)熱電(dian)(dian)(dian)路系統中(zhong),大(da)(da)部(bu)分(fen)廠家(jia)采(cai)用(yong)(yong)(yong)過(guo)去的(de)(de)傳(chuan)統模擬3525或(huo)494電(dian)(dian)(dian)路,產(chan)(chan)生(sheng)兩路或(huo)四路PWM,采(cai)用(yong)(yong)(yong)調(diao)頻方法驅動(dong)IGBT,改變(bian)諧振回電(dian)(dian)(dian)流大(da)(da)小來達到調(diao)節功(gong)率大(da)(da)小的(de)(de)目(mu)的(de)(de),再采(cai)用(yong)(yong)(yong)4046進行鎖(suo)相控制(zhi),在(zai)工業上(shang)加(jia)熱應用(yong)(yong)(yong)已經很普(pu)遍,技術也比較成(cheng)熟。但是,它的(de)(de)硬件電(dian)(dian)(dian)路復雜,所以大(da)(da)多體積龐(pang)大(da)(da),也不便于(yu)生(sheng)產(chan)(chan)和調(diao)試,特(te)別是容易(yi)由于(yu)所選用(yong)(yong)(yong)的(de)(de)器件特(te)性(xing)差異,致使(shi)電(dian)(dian)(dian)源致性(xing)差,工作中(zhong)生(sheng)產(chan)(chan)的(de)(de)高強(qiang)的(de)(de)電(dian)(dian)(dian)磁(ci)干擾時,鎖(suo)相或(huo)保護部(bu)分(fen)容易(yi)失靈,容易(yi)造成(cheng)故障。

二:電(dian)(dian)力(li)(li)(li)器(qi)件布局(ju)不(bu)合(he)理(li)。在(zai)大(da)功率(lv)(lv)(lv)工業(ye)電(dian)(dian)磁加熱主結(jie)(jie)構(gou)電(dian)(dian)路(lu)中,常為(wei)半橋電(dian)(dian)路(lu)和全(quan)橋電(dian)(dian)路(lu),通常2-25KW功率(lv)(lv)(lv)別采用(yong)半橋電(dian)(dian)路(lu),全(quan)橋電(dian)(dian)路(lu)可以(yi)實現(xian)20KW以(yi)上功率(lv)(lv)(lv)。般地,功率(lv)(lv)(lv)大(da)于(yu)25KW后,線(xian)圈(quan)的高(gao)頻電(dian)(dian)流(liu)比(bi)較大(da),發熱比(bi)較多,當主電(dian)(dian)路(lu)電(dian)(dian)力(li)(li)(li)功率(lv)(lv)(lv)器(qi)件布局(ju)不(bu)合(he)理(li)時,可能會產生高(gao)強干(gan)擾,有可能使(shi)慮(lv)波電(dian)(dian)容、揩振電(dian)(dian)容或IGBT模(mo)(mo)塊擊穿。為(wei)了用(yong)戶的安(an)裝安(an)全(quan)考慮(lv),般把半橋電(dian)(dian)路(lu)大(da)功率(lv)(lv)(lv)定(ding)為(wei)15KW,降低IGBT模(mo)(mo)塊電(dian)(dian)流(liu)應(ying)力(li)(li)(li),當功率(lv)(lv)(lv)大(da)于(yu)20KW時,建議用(yong)戶選擇全(quan)橋主電(dian)(dian)路(lu)結(jie)(jie)構(gou)。當然(ran),在(zai)特定(ding)的應(ying)用(yong)場合(he),需要加熱面積比(bi)小(xiao),功率(lv)(lv)(lv)密度(du)比(bi)較大(da)時,我們合(he)理(li)科學地可以(yi)幫助用(yong)戶把半橋電(dian)(dian)路(lu)安(an)全(quan)做到30KW。

電磁加(jia)熱器的電流(liu)小(xiao)于時,控(kong)制器會(hui)(hui)自(zi)動檢測,如果(guo)連續超(chao)過三次檢測均小(xiao)于時顯示(shi)(shi)(shi)窗1會(hui)(hui)顯示(shi)(shi)(shi)“E1”并閃爍(shuo),“電流(liu)小(xiao)”指示(shi)(shi)(shi)燈會(hui)(hui)閃爍(shuo)提(ti)示(shi)(shi)(shi),蜂(feng)鳴(ming)音每5秒(miao)短響次。解決方(fang)法:

1、確認(ren)線圈是否已正確連接(jie)。

2、檢測與低頻互感(gan)器相連(lian)的相線是否正常。

3、檢測低頻互感(gan)器是否開、短(duan)路。

4、檢測CN7連接是否正常(chang)。

5、檢測(ce)C39、DB1、R30、C41、R19、C40、C42、是否短路。

6、檢測(ce)DB1、R20、R18是否開路(lu)。

7、檢測U5第18腳是否接(jie)觸良(liang)好。
