摘要
Abstract
Water hammer in long-distance branched pressurized water transmission pipelines poses a signifi-cant threat to the safe operation of engineering projects.This study takes a long-distance branched pressurized water conveyance project in Hubei Province as the research object and employs the method of characteristics to perform numerical simulations under pump emergency shutdown conditions.The influences of the valve closing law behind the pump and the parameters of the air chamber on water hammer pressure are systematically investi-gated.The results indicate that,in the absence of an air chamber,two-stage valve closing provides superior water hammer protection compared to linear closing.However,once an air chamber is installed,the difference in water hammer mitigation performance between linear and two-stage closing becomes negligible.Based on these findings,a water hammer protection scheme that balances optimal economic efficiency with operational safety is proposed for this project.The results can serve as a reference for water hammer protection in similar en-gineering applications.关键词
