Abstract
The water hammer caused by pump-starting is an important factor affecting the safety of long-distance water supply projects.For the water supply project with multiple pumping stations,the sudden pressure rise generated when the pump is started will affect other pumping stations,and serious accidents may occur due to improper protection.Based on the basic theory of pressure transient flow,the hydraulic simulation model under different pump starting conditions was constructed.Combined with the existing hammer protection measures in an actual project,the water hammer was simulated by characteristic line method.The starting mode of each pump station was started successively at an interval of 30s,and the valve behind the pump adopted a one-stage mode with 0～1 opening degree for 30s.Under three working conditions of different unit flow,pump head and pipeline layout conditions,the pump starting simulation calculation was carried out respectively.The results showed that the water hammer pressure could meet the design protection standard under the three working conditions.关键词
