Abstract
Based on KYPipe2010 water hammer analysis software,the hydraulic transition process of the 225 group water transport main pipe was simulated and analyzed by setting different working states,and the most dangerous working conditions were simulated and analyzed around the designed flow operation steady-state working conditions and the most dangerous working conditions(i.e.the end-closing water hammer),and technical measures to protect the water hammer were explored.Through simulation analysis and calculation,technical guarantee can be provided for the safe and reliable operation of the 225 group water main pipe,and protective measures such as valve combinations and air energy storage tanks can be set up at risk points on the self-flowing water pipeline,which can effectively eliminate positive pressure overpressure and basically eliminate negative pressure,and can also provide reference for the calculation and analysis of the hydraulic transition process of other long-distance self-flowing water pipelines.关键词
