| description | To provide a vertical shaft pump which can inhibit occurrence of air suction vortexes.SOLUTION: A vertical shaft pump includes vortex breakers 20, which are respectively disposed facing a suction casing 4, on the right and left of the downstream side of the suction casing 4. The vortex breaker 20 includes: a first vortex suppression plate 21; and a second vortex suppression plate 22 disposed at the downstream side of the first vortex suppression plate 21 in a main flow direction 17. The first vortex suppression plate 21 is installed spaced apart from a center axis CL of the suction casing 4 farther than the second vortex suppression plate 22.SELECTED DRAWING: Figure 3
【課題】空気吸込渦の発生をより抑制できる立軸ポンプを提供する。【解決手段】立軸ポンプは、吸込ケーシング４の下流側の左右に、吸込ケーシング４に対向してそれぞれ配置された渦防止装置２０を備えている。渦防止装置２０は、第１の渦抑制板２１と、主流方向１７における第１の渦抑制板２１の下流側に配置された第２の渦抑制板２２とを有している。第１の渦抑制板２１は、吸込ケーシング４の中心軸ＣＬから、第２の渦抑制板２２よりも離れて設置されている。【選択図】図３ |
