BAILER-TYPE LONG-SHAFT PUMP AND APPLICATION THEREOF

摘要

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 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.
