Approaches and technical solutions of reduction of low frequency vibration caused by gas pressure oscillations in pipelines of piston compressors during suction process

One of the main sources of piston compressors pipelines vibration are low-frequency gas pressure oscillations (pulsations) spreading along pipeline main and appearing during alternating gas suction into the cylinder due to the pressure drop between cylinder recess and abutting pipeline. Approaches to reduction of low frequency vibration caused by gas pressure oscillations in pipelines of piston compressors during suction process are considered. Possible approaches include the using of gas pressure oscillations dampers, resonant dampers, acoustical filters, diaphragms, mounts etc. Analysis is showing that the most efficient solution for reduction of gas pressure oscillations in pipelines of piston compressors during suction process is using of oscillations dampers. Different technical solutions of reduction of low frequency vibration cased by gas pressure oscillations in pipelines of piston compressors during suction process are suggested. The results of approbation of some of suggested technical solutions are showing good effect of piston compressors pipelines vibration reduction.
