Some results of experimental research of low frequency gas dynamic pulsations in pipelines of compressor mounts

Abstract

Experimental researches of characteristic of low frequency gas dynamic gas pressure pulsations and caused by it noise and vibration were carried out on experimental compressor mount and in real industrial conditions. Analysis of results of experimental researches was carried out. According to results of experimental researches for compressor mount both in laboratory and in industrial conditions the maximal values of gas pressure pulsations were observed on the main frequency of compressor operation. It was experimentally shown that gas pressure pulsations are making the main contribution into forming of low frequency sound and vibration of compressor mount.
