Reduction of pressure fluctuations in the discharge lines of screw compressors

The article highlights the relevance of reducing the intensity of oscillations in the discharge lines of screw compressors. A calculation methodology for compressor flow oscillations is presented, based on the actual geometry of the screw rotors and the discharge port. Schemes for autonomous and integrated gas oscillation silencers are proposed, designed for installation in the compressor discharge pipeline and housing. The study includes an efficiency analysis of the flow pulsation silencers, demonstrating their high effectiveness within the frequency range up to 2 kHz.
