    摘要: There is disclosed a method for starting a pump, wherein when a pump runner effects the idle running in a runner chamber which is filled with compressed air, a water-pumping-up starting instruction is given, then a drain valve is first closed according to the water-pumping-up starting instruction, the aforesaid drain valve being provided in a draft tube for discharging pressurized water from a runner band chamber of the runner chamber; then compressed air in the runner chamber is discharged therefrom; subequently water is charged into the runner chamber; and after water pressure at the adjacent portion of the runner periphery in the runner chamber has been raised to a given level, a by-pass valve and a main valve in a discharge tube and guide vanes are sequentially opened; and a device for automatically substantiating the method.
