| Abstract: | The characteristic of pump-stopping hydraulic transient in cascade water supply pumping station was expounded in this paper. Combining with example, using characteristic line method, the authors analyzed some problems, as cavities collapsing with water column separation, the water level of the inlet sump of downstream station descending to empty or rising to exceed the sump top, which possibly occurred when accidental pump-stopping happened in two grade pumping stations at the same time or only one grade pumping stations. Also, the control measures were put forward in the end. |
