大规格转子压缩机止推音研究

Solution of beating-sound from compressor for light commercial air

某大规格的转子压缩机在不稳定工况下出现异常声音,结合噪音、振动的分析判断为曲系的异常轴向运动引起的上止推面撞击产生的止推音。根据止推音产生的原理,项目设计优化气流路径,增加轴向约束和稳定轴系三个方案,均可有效避免止推音产生,使压缩机噪声达到正常状态。

A compressor for light commercial air makes beating-sound because of the crankshaft beating.This experimental design three experiments for making the crankshaft works stable,and elimination of beating sound,and all three experiments are working.
