The Influence Factors Of Wave Velocity Analysis And Research On The Influence Of The Actual Project

With a range of factors of the rapid development of social economy, the increase ofpopulation and waterpollution and the regional rainfall, water resources become the mainfactor restricting the economic development of our country. Under such severe form, in orderto realize the sustainable utilization of water resources and reasonable distribution, socross-regional water diversion projects are growing, and often thewater hammer accidents arecaused by a variety of different reasons. In view of this reason, water hammercalculation andprotection at home and abroad in recent years has attracted the attention oftheprofessionals.Water hammer wave speed as one of the factors that affect water hammerpressure, is also an important research topic in the field of water hammer. I have read theinformation and analysis in the classification of its research results are summarized in thispaper on the factors affecting water hammer wave speed to do a comprehensive andsystematic exposition. Then on the basis of complete engineering examples in recent years,the specific in-depth research and analysis of water hammer wave velocity differenceinfluence on water hammer pressure.For the research course of water hammer protection and research results at domestic andoversea has also done a comprehensive introduction. then introduces the definitions of waterhammer, water hammer wave speed, focusing on the introduction of the main factors of waterhammer wave speed. This article is to determine the water hammer boundary conditions, aswell as the method of calculating water hammer.The last two chapters combined with an engineering example.One is Lu jiayao pressurestream pumping station with water hammer wave speed booster under different conditions.The other project is Li Guhe diversion project in North Route. It’s about gravity flow, largediameter of the impact on water hammer wave speed boosting water hammer analysis. Stepby step in order to meet the requirements of pressure, and make the safe operation of thepipeline. Discuss about the water hammer wave velocity affecting the size of the waterhammer pressure in hydraulic transition process unfer different situations and workingconditions gradually. This paper, the factors affecting the water hammer wave speed and the study of actualengineering project, in the end is water hammer protection theory of water hammer wavespeed in the theory part is perfect, and selected two typical engineering project to do research,for the practical engineering in the choice of water hammer scheme is doing theoreticalsupport and practical reference. Hope for our long-distance water hammer protectioncontribute render the author’s research, and for long-distance water conveyance project ofpipeline safety operation provide certain help.
