Anti-seismic centrifugal pump for nuclear power station

The invention relates to the technical field of centrifugal pumps, in particular to an anti-seismic centrifugal pump for a nuclear power station. Comprising a bottom frame, a motor and a pump shell are fixedly connected to the bottom frame, the motor is connected with the pump shell through bolts, an impeller is rotationally connected into the pump shell, an output shaft of the motor is fixedly connected with the impeller, a water inlet pipe is communicated with the side, away from the motor, of the pump shell, and a water outlet pipe is communicated with the side, away from the bottom frame, of the pump shell. A water storage tank is fixedly connected to the bottom frame and communicated with the pump shell through a pipeline, and a water injection pipe is arranged on the side, close to the pump shell, of the water storage tank. Water is supplemented into the pump shell through the water storage tank according to the difference value of the inlet amount and the outlet amount of cooling water, air is prevente
