二三天修好西門子直線電機線圈燒外殼壞;燒毀電機的原因:
1、進水后電路存在接觸不良,導致缺相運行,最終燒毀電機;
2、這樣原因燒毀的電機,打開時,只有部分繞組燒毀;
3、Y形接法的電機,燒兩相繞組,△形接法的電機,燒一相繞組;
電機如何判斷燒毀:
搖電阻
聞味
拆開看
電機進水后處理方法:
斷開電源,并且拆除電動機電源接線;
2、拆除電動機前后端蓋;
3、用汽油或者煤油把電動機軸承潤滑油洗干凈,并且干燥處理后重新加潤滑油;
4、把電動機定子用烘箱、或者燈泡進行干燥處理;
5、電動機轉子用干凈抹布擦干凈;
6、把電動機接線盒進行檢查處理;
7、電動機整體安裝恢復,并且用手轉動靈活無卡塞;
8、用搖表(500或者1000V)測量電動機對地絕緣,并且絕緣電阻必須大于0.5兆歐;
9、接上電源試(shi)運(yun)行(xing)一段時間(30分鐘),如(ru)果沒有(you)問題即可使用。
