#4炉A磨煤机电流晃动、联轴器频繁断销难题的解决

针对国产300MW火力发电机组配套350/600型低速钢球磨煤机因长期运行出现大小齿轮齿面磨损严重造成的磨煤机小齿轮轴承座振动大、联轴器尼龙销断裂及电机电流晃动现象,经过对大小齿轮及联轴器解体和研究,找出原因并进行了相应的检修,消除了磨煤机大小齿轮工作齿面磨损严重所造成的振动超标、联轴器尼龙销断裂及电机电流晃动的缺陷。

The long-term movement appears the pulverizer pinion bearing seat because in view of the domestically produced 300MW thermoelectricity generation unit necessary 350/600 low speed ball mill which the big and small gear tooth face wears creates seriously to vibrate big,the shaft coupling nylon sells the break and the electrical machinery electric current rocks the phenomenon,passes through to the big and small gear and the shaft coupling disintegration and the research,discovered the reason and has carried on the corresponding overhaul,eliminated vibration exceeding the allowed figure,the shaft coupling nylon which the pulverizer big and small gear work tooth face wore seriously creates has sold the flaw which the break and the electrical machinery electric current rocked.
