Analysis and Protective Measures for Water Hammer of Circulating Water System

根据某电厂循环水系统设备选型和管道布置情况,通过数学模型模拟计算,求出不同运行工况的管道沿程最高压力、某些特定断面不同时刻的水力要素等,提出泵房和输水管道可采用的水锤防护措施,在工程设计中付诸实施。

Based on the equipment selection and pipeline arrangement of the circulating water system for a power plant,the paper calculates the highest pressure along the pipeline under different operating conditions and the hydraulic elements of some specific section at different time points by simulating mathematical model.And the protective measures for water hammers at pump room and pipeline are put forward,which can be put into practice in project design.
