Water hammer analysis device and water hammer analysis method

摘要

PROBLEM TO BE SOLVED: To easily verify whether the analysis of a water hammer phenomenon is performed correctly without using knowledge of a special program language, and to easily confirm the validity of the analysis result. SOLUTION: In a water hammer analysis device 10 for analyzing a water hammer phenomenon generated by a change in the head and flow rate of a fluid in a pipeline, a pipe specification recording spreadsheet 11 for recording pipe specification information of each part of the pipeline and a pipe specification recording spreadsheet 11 Water hammer analysis parameter information spreadsheet 12 (advancing wave information value spreadsheet 14, backward wave information value spreadsheet 15, flow value spread) that records the time history of water hammer analysis parameter information including the head and flow rate in each part of the pipeline. Sheet 16, head value spread sheet 17), and calculation means 13 for calculating the current time value of water hammer analysis parameter information by a calculation formula using the value of pipe specification information and the previous time value of water hammer analysis parameter information. A display means 18 capable of displaying a calculation formula of a calculation means for different times. [Selection diagram] Fig. 1
