Investigation of Low-Frequency Noise, in Order to Reduce it During the Operation of Compressor Mounts

Abstract

Experimental researches of characteristic of low frequency noise and gas dynamic gas pressure pulsations were carried out on experimental compressor mount and in the real industrial conditions. It is shown that gas pressure pulsations are making the main contribution into forming of low frequency noise of compressor mount. New device of reduction of low frequency noise and dynamic pressure pulsations was suggested. The device is allowing us to reach simultaneous efficient reduction of noise and pressure pulsations during operation of compressor mounts and to reduce the risk of the accidents in industrial conditions.
