電磁(ci)加熱器(qi)的全橋(qiao)和半(ban)橋(qiao)的投(tou)資(zi)成本(ben)與產品配(pei)置(zhi)的異同：

、相同：在普(pu)通用途上，均(jun)可全(quan)系列配置各種產品(pin)。

二、投資成本上不(bu)同：

1、全橋：因其設計配(pei)置較高，無可避(bi)免生產成本較高。

2、半橋：因其設計配置較(jiao)低，生產成本較(jiao)低。

三、產品配置上：

1、全橋(qiao)：成本合理(li)和(he)負載耐用上，配置(zhi)30KW以上產品較(jiao)宜。

2、半(ban)橋(qiao)：成(cheng)本合(he)理上，配置30KW以下產品(pin)較宜。

電磁(ci)加(jia)(jia)熱(re)器在(zai)油(you)田(tian)管(guan)道中的應用(yong)：冬季由(you)于野外(wai)氣(qi)溫(wen)較低，在(zai)油(you)由(you)管(guan)道中石油(you)中含蠟量(liang)高，管(guan)件容易(yi)凍堵。傳(chuan)統的方式(shi)是用(yong)火(huo)燒，但是用(yong)明(ming)火(huo)違反(fan)了(le)采油(you)區禁止明(ming)火(huo)的安(an)全規(gui)定(ding)，易(yi)發生安(an)全事故，電熱(re)發熱(re)板(ban)加(jia)(jia)熱(re)又(you)破壞了(le)原有的保溫(wen)層(ceng)，且熱(re)量(liang)散失(shi)大(da)，速度(du)漫，時間長，功耗大(da)。用(yong)錯能電磁(ci)加(jia)(jia)熱(re)器，機(ji)組磁(ci)力可(ke)以穿(chuan)過保溫(wen)層(ceng)、纖(xian)維布等保溫(wen)材料以感應的方式(shi)快速對管(guan)道自身加(jia)(jia)熱(re)。

電(dian)磁加(jia)熱器優(you)(you)點電(dian)磁感(gan)應(ying)加(jia)熱優(you)(you)勢(shi)：

1、非接觸電磁感應加熱。

2、耗電的 95% 轉化(hua)為工作(zuo)熱能。線(xian)圈損(sun)耗 ≈ 2%, 控制單元損(sun)耗 ≈ 2%, 緣(yuan)隔熱層可以將98%的能量保留在料筒上(shang)。

3、只加熱料筒，而螺桿(gan)保持(chi)冷(leng)卻。

4、消(xiao)除加熱的慣(guan)性(xing)現象，升(sheng)溫(wen)降溫(wen)迅速(su)。

5、加(jia)熱無死(si)角，整體料筒均勻加(jia)熱。

6、電磁線(xian)圈保持涼爽(shuang)，因此壽命超(chao)長(chang)。

普通(tong)加(jia)熱圈加(jia)熱方(fang)式:接觸(chu)式熱傳遞加(jia)熱：

1、耗電的 30-70% 轉化為工作熱能。

2、加(jia)熱通過接觸方(fang)式傳遞熱能。

3、加熱及冷卻都有慣(guan)性現象產生，及升溫降溫都緩(huan)慢。

4、加熱有死角(jiao)，不能完全(quan)包裹在(zai)料筒外層。

5、加熱圈損耗(hao)大，壽(shou)命短(duan)。

電磁加熱控制器怎么安裝？

1、改造前先取下原設備(bei)上(shang)面的電熱圈。

2、清潔(jie)(jie)料筒并(bing)測量料筒各種(zhong)參數。將(jiang)料筒清潔(jie)(jie)干凈并(bing)用工具(ju)測量料筒各種(zhong)尺寸（管徑、長(chang)度(du)、加熱區(qu)數、每區(qu)加熱長(chang)度(du)、原(yuan)功率大小，以(yi)便確定(ding)用哪種(zhong)控(kong)制板）。

3、在(zai)料筒(tong)上包層隔熱保溫材料，按照步驟(zou)2將料筒(tong)清潔干(gan)凈(jing)后，在(zai)料筒(tong)上包上層隔熱保溫材料（石棉或者(zhe)玻璃纖維均可(ke)(ke)），可(ke)(ke)以(yi)先做(zuo)區(qu)(qu)(qu)，區(qu)(qu)(qu)做(zuo)好(hao)后，再做(zuo)其它區(qu)(qu)(qu)，熟練且經驗豐富者(zhe)可(ke)(ke)幾個加(jia)熱區(qu)(qu)(qu)起做(zuo) 。

4、用高(gao)溫(wen)布將(jiang)保(bao)(bao)(bao)(bao)溫(wen)材(cai)(cai)料(liao)包(bao)好，保(bao)(bao)(bao)(bao)溫(wen)材(cai)(cai)料(liao)的(de)厚(hou)度(du)根據使用的(de)不同的(de)電磁(ci)加(jia)(jia)熱控制器(qi)的(de)要求來(lai)配，保(bao)(bao)(bao)(bao)溫(wen)材(cai)(cai)料(liao)包(bao)好后，再用高(gao)溫(wen)布（纖維布）或者電木板(ban)(ban)（環(huan)氧(yang)樹脂板(ban)(ban)）將(jiang)保(bao)(bao)(bao)(bao)溫(wen)材(cai)(cai)料(liao)包(bao)緊起來(lai)，該步驟(zou)主要是確保(bao)(bao)(bao)(bao)料(liao)筒各處的(de)保(bao)(bao)(bao)(bao)溫(wen)材(cai)(cai)料(liao)厚(hou)度(du)致(zhi)，以保(bao)(bao)(bao)(bao)證電磁(ci)加(jia)(jia)熱的(de)磁(ci)場均。

5、纏繞高溫電纜(lan)，高溫電纜(lan)的規格與長度請根據各(ge)種不同型號電磁加熱(re)控(kong)制器的要求選配，該步驟非常關鍵。

6、將線圈(quan)與(yu)電(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)控(kong)制(zhi)器連接。則將繞好(hao)的(de)線圈(quan)與(yu)電(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)控(kong)制(zhi)器連接好(hao)，并給(gei)電(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)控(kong)制(zhi)器接上(shang)電(dian)(dian)(dian)源，即可對設備進行調試，需(xu)注意(yi)的(de)是調試過程中要(yao)特(te)別注意(yi)測量(liang)電(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)控(kong)制(zhi)器的(de)輸入電(dian)(dian)(dian)流(liu)(liu)與(yu)頻率。為保(bao)證設備的(de)使用壽命(ming)建議電(dian)(dian)(dian)流(liu)(liu)調到額定(ding)工作(zuo)電(dian)(dian)(dian)流(liu)(liu)的(de)80%左(zuo)右，如我司2.5KW的(de)電(dian)(dian)(dian)磁(ci)加(jia)(jia)熱(re)控(kong)制(zhi)板，額定(ding)工作(zuo)電(dian)(dian)(dian)流(liu)(liu)是12A，則建議調到10A左(zuo)右即可，或電(dian)(dian)(dian)流(liu)(liu)偏(pian)小則可減少線圈(quan)，反之(zhi)則需(xu)再(zai)增加(jia)(jia)些(xie)線圈(quan)。
