Influence of Pressure Distribution between the Gas Control Valve and Damper Stages on the Damper Efficiency

In the paper, results of theoretical and experimental study of the pressure distribution between pulsation damper stages and the gas pressure control valve are presented. It is shown that the pressure distribution mode affects the damper efficiency and allows to provide required vibroacoustic characteristics of the gas pressure control system as a whole. There are considered several typical modes of pressure distributions. The most effective design solution is a multistage throttling type pressure pulsation damper having equal pressure ratios at each damper stage. The calculated data were confirmed experimentally.
