Monitoring And Control Study Of Steam & Water Pipe Vibration In Thermal Power Plant

On soda piping vibration in thermal power plants in practical engineering problems were investigated, reduce and control the pipeline vibration, avoid pipe line due to the vibration and rupture and severe injury, is to guarantee safe production power plant, improve the economic benefit, as the foundation of the national economic construction to provide a stable enough power to support. This article through to the coal-fired power plant steaming-water pipe vibration problem thoroughly understand and grasp, targeted analysis of the soda, the influence factors of pipeline vibration; A detailed account of the current widely used vibration reduction measures and the commonly used damper damping device; Describes the engineering practice, based on which the method and principle of piping vibration measuring.In practical engineering, the pipe vibration problem the impact factor is various, working environment is very complex, the pipe vibration problem needs both basic theory as a guide pipe vibration, comprehensive analysis for the cause of pipeline vibration, further find reasonable management way, also need to modal analysis and stress calculation in the piping system for vibration control on the basis of the final solution. Through on-site investigation, pipeline vibration measurement and modal analysis, the successful management of a subcritical air cooling unit air cooling the condensate water pipe vibration problem of governance and a circulating fluidized bed unit medium pressure, low pressure water supply pipeline vibration, the main cause of pipeline vibration, and modal analysis and stress calculation in the piping system developed on the basis of the method to control vibration and vibration reduction effect is remarkable, governance pipeline vibration after fully meet the engineering requirements. A lot of valuable experience has been obtained, and the follow-up work is also very important guiding significance.
