Abstract (English):
The operation reliability of power units is defined to a great extent by their vibration state, where a basic source of exciting effects is shafting. For the thorough analysis of a vibration state of turbine units the special vibroacoustic investigations are necessary in the course of which there are must be defined: characters of vibration processes, increased vibration reasons, phenomena promoting the intensification of vibration processes in power units. With the purpose of systematization and accu-mulation of such materials there were carried out in-vestigations of vibro-activity of gas-compressor units (GCU) with marine gas turbine drive and working at compressor plants of gas-main pipelines. The plant of GPA-16MG90 type with the power of 16MWt was an object of investigations, where a marine convertible DG-90 manufactured by production company “Zarya” was used as a drive for a natural gas super-charger of 370-18-1 NZL type. The results of measuring indicate the necessity for taking measures to eliminate an increase vibration of a supporting – thrust bearing of the supercharger and gas turbine engine of DG type.
