Vyladenie mechanickej sústavy pohonu piestového kompresora z hľadiska veľkosti torzného kmitania

Abstract

One of possible ways to change the amount of compressed air delivered by a piston compressor is to change its operating speed. However, it can cause an improper tuning of the mechanical system of piston compressor drive in terms of torsional dynamics. In order to avoid excessive torsional vibration, a suitable pneumatic flexible shaft coupling can be used in the system. An optimum air pressure value in a pneumatic coupling was determined experimentally for three various operating modes of an experimental mechanical system of piston compressor drive.
