ンプの吸入通路構造。 In a suction passage structure of a centrifugal pump having a suction passage communicating with an impeller chamber and a conduit connected to the suction passage, the suction passage has a minimum inner diameter that is substantially the same as the inner diameter of the conduit in the middle. The pipe has a diameter portion, and has a tapered shape that widens toward the impeller chamber from the minimum diameter portion, and the conduit is inserted into the opposite side of the impeller chamber from the minimum diameter portion. A suction passage structure for a centrifugal pump, characterized in that a conduit receiving enlarged diameter portion is formed adjacent to the minimum diameter portion and has an annular stepped end surface that contacts the tip end surface of the conduit.
