摘要
管道振动和转机振动是工程两大振动问题,水锤的冲击力常诱发管道的振动破坏。以核电厂中典型复杂管系为研究对象,首先基于FloMASTER软件的瞬态分析功能,结合现场振动测试数据,研究了复杂管系水锤机理归因的分析方法,并结合使用流网仿真分析及频谱图确定了水锤的主要诱因。然后,针对典型管系的水锤问题,通过流网仿真分析方法,提出了针对性的水锤预防措施。研究结果表明:关阀水锤关键扰动区在阀门上游;基于水锤归因分析给出的针对性治理措施可以有效缓解水锤现象。
Pipeline vibration and rotary vibration are two major vibration problems in nuclear power plant,the impact force of water hammer often induces the vibration damage of pipeline.In this paper,based on the transient analysis function of FloMASTER software and the field vibration test data,the mechanism attribution analysis method of water hammer for complex piping in nuclear power plant is studied.The results show that the main inducement of water hammer can be determined by the combination of flow net simulation analysis and spectrum diagram.Then,aiming at the problem of water hammer in typical pipe system,this paper puts forward the preventive measures of water hammer through flow net simulation analysis method.The results show that the key disturbance area of the water hammer is upstream of the valve.Targeted treatment measures based on water hammer attribution analysis can effectively alleviate water hammer.
