Poster – Vibration limits | Screw compressors

Screw compressors fill the gap between reciprocating compressors and turbo compressors. For specific conditions they are the preferred and most efficient technology available.

From a vibrational point of view a special treatment is advised for screw machines. Compared to a reciprocating compressor less mass forces are present and beside the fact of having meshing effect of the rotors the machine behaves like a turbo. But due to the working cycle the gas flow at the discharge port is pulsating comparable to the reciprocating compressor. This leads to the necessity of considering the gas acoustics of machine, piping and oil separators to overcome standing waves resulting in excessive noise and vibrations.

Our guideline chart will enable you to assess the operational vibrations of screw machines. It is based on the VDI guideline 3836 and will provide you with the information needed to judge whether your machine is running fine or not.
