Numerical Computation on Hydraulic Transient Process in Long Distance Water Transfer System and Design of Handling Measures
Dynamic simulation on transient process of long distance water transfer system using Hammer software clearly shows the overlapping of water hammer due to negative pressure in piping at the transient state with the development of pressure wave.Triple acting air valve and surge relief valve are established appropriately in the piping system and hydropneumatic tank is established at the outlet of the pump station based on simulation,effectively eliminating water hammer in the pipe system at transient state and ensuring safety of transient process of the water transfer system.
