The investigation of vibroacoustic characteristic of gas-pumping units of GTK-10-4 type. Power units improvement, as a rule, results in the decrease of units steel intensity and under conditions of the increase of airgas flows and facilities developed it causes a growth of vibroacoustic activity of plants elements. Taking into account this factor, it is necessary to develop measures to reduce noise and vibrations in sources of their origin at the design elaboration both at the stage of design, and at the stage of reengineering. With this purpose there are carried out the investigations of noise and vibration characteristics of a gaspumping unit of GTK-10-4 type equipped with a sta-tionary gas-turbine unit with a capacity of 10 MWt and a natural gas supercharger of 520-12-1 type manufactured by NZL. The noise and vibration sources of impeller ma-chines are studied, their vibroacoustic characteristics are analyzed, and the methods to reduce vibroacoustic activity of gas-pumping units of such a type operating at compressor stations of trunk pipelines are offered.
