Discussion on Water Hammer Protection Scheme for Pressurized Water Delivery System
Water hammer is a very common phenomenon in pressurized water transmission systems,and water hammer protection for long-distance,high-lift and large-flow water transmission projects is particularly important for the safety of project operation.Through the discussion of the water hammer phenomenon,the basic factors that cause water hammer are analyzed,common water hammer protection measures are sorted out,and corresponding water hammer protection plans should be adopted for different situations;the design parameters such as flow rate,pipeline layout,pipe material,pipe length and maximum working pressure of the pipeline are analyzed,and the water hammer protection measures suitable for the actual project are selected through engineering cases,such as flow regulating and pressure regulating valves,two-stage slow closing valves,air valves,air tanks,overpressure relief valves,pressure regulating towers and increasing the moment of inertia of the unit,so that the system water hammer hazards are effectively alleviated,which can provide experience and reference for similar projects.
