<p>PROBLEM TO BE SOLVED: To provide a vertical shaft pump device capable of effectively suppressing the vibration of a pump casing under a pump installation floor and preventing an air suction swirl as a vibration generating source vibrating the pump casing from occurring. SOLUTION: In this vertical shaft pump device having a vertical shaft pump 10 installed on the pump installation floor 14 above a suction water tank 16 and allowing a pump weight to be supported by the pump installation floor 14, a straightening device 25 having a straightening plate for straightening the water flowing into a suction bell mouth 12 is installed on the bottom surface of the suction water tank 16 located at the lower tip side of the suction bell mouth 12 of the vertical shaft pump 10. The suction bell mouth 12 is fixed to the straightening plate device 25.</p> |
