风冷螺杆机组减振降噪技术研究

On Vibration and Noise Reduction Technology of Air-cooled Screw Unit

风冷螺杆机组噪声控制主要包括消声和隔振两个方面。作者分析风冷螺杆机组噪声源主要来自压缩机和风机,以此提出了风冷螺杆机组噪声控制方法,根据振源提出了合理的隔振减噪措施,并以某办公楼风冷螺杆机组为例进行了隔声和减振设计,风冷螺杆机组达到了允许的噪声标准.

Noise control of air-cooled screw unit mainly includes noise elimination and vibration isolation.The author holds that the noise source of the air-cooled screw unit mainly comes from the compressor and fan,then puts forward the noise control method of the aircooled screw unit,and propounds reasonable vibration isolation and noise reduction measures according to the vibration source.Taking an air-cooled screw unit of office building as an example,the author considers that the air-cooled screw unit is designed for sound insulation and vibration reduction,and the air-cooled screw unit meets the allowable noise standard.
