科晶高溫箱式電阻爐常見的故障和解決故障問題的處理方式
新聞分類:  技術資訊    瀏覽:1440    日期:2021/11/16    
高溫箱式電爐是通用的加熱處理設備.有箱式爐管式爐坩堝爐。高溫箱式電阻爐應放在干燥通風、無腐蝕性氣體的地方,工作環境相對溫度不大于85%環境溫度最好為10—50℃度。大多是硅碳棒爐型如果硅碳棒損壞了,必須換規格相同電阻值相近的硅碳棒,沒有配到電阻值相近的硅碳棒建議更換一組新的硅碳棒,電阻值規格相差過大會燒壞其它不同的硅碳棒。

高溫箱式電阻爐常見故障有如下幾種:

第一種高溫氣氛爐不升溫


    電源電壓控制器工作都正常但是電流表沒有任何顯示,可能出現電爐絲斷路故障,要使用萬用表檢查并且更換相同規格的電爐絲。電源電壓控制器不工作了可檢查控制器開關熔斷器爐門的行程內部開關。電爐的爐門沒有關好控制器也不能工作,建議參考控制器說明書來檢修此類故障。如果供電電源出現故障在不接通電爐時工作正常,接通電爐后不工作的故障,可查看控制器內部有持續噠噠聲,是因為供電線路的電壓降太大也可能是插座或者控制開關接觸不良等情況建議更換排除法檢測。

第二種高溫箱式電阻爐升溫速度非常慢

電源電壓控制器工作正常,可能是有電爐絲斷路的情況,使用萬用表檢查更換相同規格電爐絲。電源電壓正常,但是電爐的工作電壓低,其原因為供電線路的電壓降太大或者控制開關和插座接觸不良。電源電壓要比正常電壓低的話電爐工作時加熱功率不足。三相電源缺相需要調整檢修操作。

第三種高溫箱式電阻爐溫度異常情況

  那么可能是熱電偶沒有插入到位在爐膛內不平衡所造成爐溫失控的情況,熱電偶分度號和溫控儀表的分度號不一樣,將造成爐溫和溫控儀表顯示的溫度也不一樣。高溫箱式電阻爐的一些常見故障基本情況以表述,遇到問題請耐心排查,工作細節到位就能解決很多問題。也能避免很多故障的發生。
