Aerated swirling vertical shaft with double volute chambers
An aerated swirling vertical shaft with double volute chambers comprises an upper volute chamber (2) and a first shrinking section (3) beneath the upper volute chamber (2), a venting passage (4) outside the upper volute chamber (2), a vertical shaft section (7) beneath the first shrinking section (3), as well as an aerated lower volute chamber (5) and a second shrinking section (6) communicated with the aerated lower volute chamber (5) between the first shrinking section (3) and the vertical shaft section (7), wherein the upper end of the aerated lower volute chamber (5) is connected with the first shrinking section (3), the lower end of the second shrinking section (6) is connected with the vertical shaft section (7); the upper end of the venting passage (4) is communicated with the atmosphere and the lower end is communicated with the aerated lower volute chamber (5). The water stream in the vertical shaft can be discharged smoothly and the wall surface of the vertical shaft may avoid being destroyed due to cavitation and cavitation erosion.
