自行判斷電熱烘箱故障問題

發布日期:2022-05-30 點擊率:106

  電熱烘箱是很常用的干燥設備,那么這些工業設備很容易出現故障,那么電熱烘箱出現問題的時候要怎么辦呢?

  電熱烘箱如果出現以下問題的時候,我們可以先自行判斷以下:

  如果電熱烘箱無風或風很?。何覀儜摍z查風葉輪是否反轉,若反轉應把電源線任意兩線對換;風葉輪掉下來,應打開烤箱門,取下頂部風葉輪蓋板,把風葉輪重新裝上去,螺絲旋緊,再蓋上蓋板;送風馬達不轉,檢查電源是否缺相,缺相應當立即關機檢查電源線,或者馬達燒壞,應更換馬達。

  如果溫度不下降:要看看電熱接觸器觸頭燒壞咬死,電熱電源不能斷開,應更換接觸器;溫度表損壞,應更換;感溫線損壞,應更換。

  如果溫度長不上:要看看發熱管繞壞,應折掉烤箱右邊發熱管蓋板,更換發熱管;發熱管電源線燒斷或接觸不良,應重新接線。
