Abstract:
In this paper, the effect of different supply pressures on the filling characteristics of gas in pipeline is studied by experimental research and theoretical analysis.The tested results show that when the gas velocity at the throat of venturi-tube is equal to the sound velocity, and the gas medium and the throat area of venture-tube is unchanged, the change of supply pressure has little effect on the pressure buildup time and pressure release time before injecting during the initial stage of pressure change.Throngh theoretical analysis, the relationship between the supply pressure and the filling characteristics of the gas pipeline was obtained, and the method of rapidly determining the filling characteristics of the gas pipeline at different pressures was found.
