摘要
通过振动测试和分析,确认引起机组轴系振动的原因,并根据影响系数法按转子质量由大到小依次进行轴系动平衡测试,同时综合带负荷后转子振动变化趋势,最终降低了整个轴系振动。
Through vibration tests and analysis, the cause of the shaft system vibration is surely found. According to influencing coefficient method, the shaft system is dynamic balanced according to the magnitude of rotor masses, and in conjunction of the variation tendency of the rotor while loading, the vibration of the shaft system is reduced at last.
