浅谈汽轮发电机组的振动与平衡

通过对汽轮机转子的横向振动、汽轮发电机组的轴系扭振、震源、振动试验及分析、振动的测量与标准、常见的振动原因及消除对策、刚性转子平衡、挠性转子平衡、轴系平衡等方面进行分析,得出汽轮发电机组产生振动的多数情况是由于质量不平衡引起的.论述了解决质量不平衡是减轻机组振动、保证机组轴系平衡和安全经济运行的最有效途径.

Discussion on Vibration and Balance of Turbogenerator Unit

Through analysing lateral vibration of the turbine rotor,torsional vibration of shaft,vibration source,vibration test and analysis in turbogenerator unit,measurements and standards of vibration,common vibration reason and countermeasure of eliminating,rigid rotor balance,flexible rotor balance,balance shaft and so on,obtains that vibration of causing by turbogenerator unit is due to the imbalance caused by the quality in most cases.Discusses it is the most effective way that solves the imbalance of the qual...
