Disclosed are a bailer-type long-shaft pump (100) and an associated pump station (200). The long-shaft pump comprises a bailer vehicle (110), a long shaft (120), a bearing (130), a transmission device (140) and an electric motor (150). One end of the long shaft (120) successively passes through the bearing (130) and the transmission device (140) so as to be in transmission connection with a drive shaft of the electric motor (150). The pump station (200) comprises a pump station foundation (210), several equipment rooms (231) transversely distributed at intervals and constructed on the pump station foundation (210), and two ends of the long shaft (120) are supported on side walls of two adjacent equipment rooms. The bailer-type long-shaft pump achieve large water flow and low lift, the pump station is space-saving, has shorter construction cycle, and reduces investment and operation costs.

Disclosed are a bailer-type long-shaft pump and a pump station constructed using the long-shaft pump. The long-shaft pump comprises a bailer vehicle (110), a long shaft (120), a bearing (130), a transmission device (140) and an electric motor (150). The transmission device comprises a planetary gearbox (141), an orthogonal shaft gearbox (142) and a frequency converter (143); one end of the long shaft (120) successively passes through the bearing (130), the planetary gearbox (141), the orthogonal shaft gearbox (142) and the frequency converter (143), so as to be in transmission connection with a drive shaft of the electric motor (150); and the bailer vehicle (110) comprises a cylindrical base (112) and at least three blades (111) distributed on the surface of the cylindrical base (112) in an annular array radially extending from the center of the long shaft. Two adjacent blades and the surface of the cylindrical base forms a bailer capable of bailing water from a lower water side of a channel to a higher water side of the channel. The pump station (200) comprises a pump station foundation (210), several equipment rooms (231) transversely distributed at intervals and constructed on the pump station foundation (210), and two ends of the long shaft (120) of the bailer-type long-shaft pump (100) are supported on side walls of two adjacent equipment rooms.

The present invention relates to an apparatus for converting rotation into fluid flow and/or fluid flow into rotation. The apparatus comprises a first coiled fluid conduit and a second coiled fluid conduit and a fluid separator for separating a first fluid from a second fluid having a second density different from the first density. The fluid separator is configured in such a way that when, during rotation of the fluid conduits first mass portions of the first fluid and second mass portions of the second fluid are alternatingly transported by the first fluid conduit into or from the fluid separator, third mass portions of the first fluid and fourth mass portions of the second fluid are alternatingly transported from or to the fluid separator by the second fluid conduit. A ratio between each of the first mass portions and each of the second mass portions is substantially greater than a ratio between each of the third mass portions and each of the fourth mass portions. This provides for a net flow of one of the first and second fluids through the apparatus.
