Assessment of the negative impact of low-frequency vibrations on technological pipelines of compressor stations

The intensive development of gas transport and compressor manufacturing aimed at increasing the unit capacities pumping units, creating high-flow centrifugal compressors, productivity shops has led to appearance fundamentally new problems in diagnosis industrial pipelines. reasons for premature failure piping manifold stations can be associated with both high static voltage pipelines a level vibration. main increased vibration technological significant disturbing forces flow, coincidence natural frequencies pipeline system elements forces, low dynamic stiffness pipeline- support or combination above conditions. most effective method studying such as low-frequency vibrations is engineering means calculating processes results measurements parameters these real systems operating modes stations. hypotheses occurrence are considered during study, acoustic properties process piping, resonant conditions calculated. A computer model was created ANSYS Workbench software order consider loading piping. Based on Gazprom company standard 2-2.3-324-2009, an algorithm proposed that practical importance engineers plant diagnostics transmission equipment. It combine performance vibroacoustic studies computing modeling determination trends technical condition analysis changes vibro-parameters. As result work, direct vibrodiagnostic specialists station were compared obtained data. Some methods reduce impact design unacceptable vibrations.
