Analysis And Practice About The Water Hammer In Long Distance Transmission

This article is based on Mopanshan long-distance water pipeline, first,it is setting out the meaning and purpose of establishing a long-distance water pipeline project database. Collectting of a large amount of information and the basis of data, Establishing a detailed database about Mopanshan water project. Introductting the corresponding various systems of the structure and function of each part,database system project will be introduced to the Mopanshan long-distance water pipeline. As a project management system, either management software or analysis software can read database content , pipeline can achieve digital information .This paper discusses the waterline hydraulic simulation status of the theory and relevant methods , and endpoint of the various boundary conditions were fairly detailed, from the overall analysising the water supply pipelines in the design,operation and management.While simulatting and analysising the hydraulic conditions of the long-distance water pipeline. This pipeline is gravity flow, For there is no negative pressure and the pipeline is in steady state , while maintaining a full range of pressure at the lower level, we need to rationalize the layout of pipelines energy measures . Closing valve too fast can cause water hammer, leading to serious incidents of burglary . Therefore it must establish dynamic hydraulic models for the analysis of the hydraulic pipes dynamic simulation, and eliminate hidden dangers . From the velocity of water hammer, introduced water velocity factors and the impact of the U-shaped related issues, through experimental model , experimental observation of the course of the phenomenon , theory and practice of combining fully explained the causes of water hammer and protective .Finally, combinatting the theory and practical application through the hydraulic calculation of water hammer and boost value analysis .The theory has been used to solve engineering problems, pipeline decompression and discuss the correlation method .This dissertation solves the real problems of engineering by translating the theory into the reality.
