resent situation of parallel running process. The article raises optimization of the operating proceduresРto avoid hydraulic shock and increasing the number of running pump can effectively widened flowРadjustment range. The article also provide to change the outlet emergency cut-off valve into regulator, thenРthe pipeline characteristic changing to match the system flow ,which can effectively reducing the increasingРrate of flow and the risk of pump overload parking . On the analysis of the natural gas pipeline pressureРtendency, the paper puts forward the higher the line pressure the more conducive to the smooth operation ofРthe high-pressure pump and effective measures to ensure the unit with safety, reliable and high efficiency.РKeywords: LNG terminal;high-pressure pump;parallel control
