Research on water hammer protection of water conveyance system of pumping station based on valve adjustment of pump back
As an important measure to alleviate the uneven spatial and temporal distribution of domestic water resources,the operation safety of water delivery projects become the focus of research.This study takes a water delivery project in a city in the western region as the research object.By combining the basic theory of water hammer with numerical simulation,the overpressure of the pipeline after the pump caused by the power failure of the water pump in the high-lift water delivery system with air tank protection and the effectiveness of the adjustment of the ball valve after the pump are studied.The results show that the reasonable operation method of opening and closing the ball valve after the pump can effectively solve the overpressure problem of the wa-ter delivery pipeline,reduce the volume of the air tank required for the project,and reduce the construction cost.
