结合具体管道工程,建立水锤数学模型,运用特征线法得出水锤压力的计算式,并对3种非稳定流工况水锤防护方案进行探讨。研究表明,方案三能够将水锤压力控制在安全范围内,符合水锤防护目标。
Combined with the specific pipeline project, the mathematical model of water hammer is established, and the formula of water hammer pressure is obtained by the characteristic line method. The water hammer protection schemes of three kinds of unsteady flow conditions are also discussed. The research shows that the third scheme can control the water hammer pressure within the safe range and meet the water hammer protection target.
