Study on Water Hammer Suppression of Pipeline in Opening Process of Ultra-supercritical Steam Trap
摘要
Abstract
Aiming at severe vibration phenomenon of pipe behind the ultra-supercritical steam trap during the valve-opening process,the transient model on water hammer in the pipe was calculated by method of characteristics (MOC).Based on Matlab software,the time domain curves of flow and water hammer pressure head on fluid was obtained in different flow characteristic and different throttling effect for valve.The analyses show that adopting equal percentage flow characteristic about the valve could alle-viate water hammer in the pipe.Moreover,the influences of throttling effect for steam trap on water hammer are obvious,and the more obvious the throttling effect for steam trap,the more relieving water hammer wave and the smaller water hammer pressure head peak.The results provide theoretical references for design of steam trap in preventing water hammer and anti-shock analysis of the fluid on pipeline.关键词
