Development and application of vibration improvements
Autor: Dr.-Ing. Johann Lenz (2010 – EFRC in Florenz)
Piston compressors are used in very different industrial sectors. Big advantages of these compressors are the variable operating conditions, the good efficiency and the manifold possibilities of flow regulation. The dynamic behaviour of the piston compressors and the connected piping depends strongly on these basic conditions. Therefore, this influence must not be neglected in vibrational investigations. Compared to other compressor systems, at piston compressors the influence of acoustic induced vibration has to be considered together with the connected pipe work. Increased structural vibrations can be caused by mechanical and often by acoustic resonances, too. Accordingly, measures for an effective vibration reduction have to be adjusted. In this article an approach for a vibration investigation is described on the basis of two case-studies with adjusted measures applicable at acoustic and mechanical resonances.
