　　2.1 機械故障。
　　機械性故障包括電樞動平衡破壞、傳動機械不良、安裝不良松動、軸承不良、未灌潤滑脂或潤滑脂太少或太多等問題,主要通過重新校正平衡以及更換相應(yīng)設(shè)備等措施進行故障排查。機械故障是難以避免的,正確解決機械故障可以有效保證電機的正常運行。
　　2.2 電氣故障
　　直流電機運行的電氣故障主要表現(xiàn)在以下幾個方面:(1)運行過程中溫度升高(2)電刷下火花強烈引起換向片燒黑(3)電機絕緣性能下降,絕緣老化速度加快等。
　　運行中的溫度升高主要由電機過載、冷卻系統(tǒng)工作不正常、電樞線圈短路等原因所致。處理過程中要找準引起溫度上升的原因,并對相應(yīng)部位進行檢修維護。
　　電刷下火花強烈引起換向片燒黑的部分原因分析及處理措施如下表:
　　3結(jié)語
　　直流電機的維護保養(yǎng)決定其正常運行;直流電機結(jié)構(gòu)的特殊性決定其故障的多樣性和故障診斷的復(fù)雜性。電機的維護保養(yǎng)與故障診斷息息相關(guān),合理的維護不但可以盡量避免故障的發(fā)生,延長電機的使用壽命,而且可轉(zhuǎn)化為經(jīng)濟效益。只有正確維護,準確診斷,電機才能實現(xiàn)穩(wěn)定地運行。

一條街區(qū)里，遍布著數(shù)十家五金店鋪，要在林立的同類市場上出人頭地，做出與眾不同的業(yè)績，可不是件容易的事。他反復(fù)思考，找到了門道，覺得經(jīng)銷三角帶范圍太狹窄，且顧客常常反映三角帶有這樣那樣的毛病。為了拓寬市場滿足客戶需求，湯學(xué)秋首先更新產(chǎn)品，他從原先經(jīng)營三角帶為主改換成以工程塑料為主，分四大門類，數(shù)百種乃至上千種商品，擴寬了財路。其次，學(xué)習(xí)他人的經(jīng)驗，改正自己的不足。其三，出手果斷。瞄準市場，該出手時就出手。
