Abstract

The invention discloses a vertical axial flow pump comprising an elbow-shaped water inlet channel, a siphon type water outlet channel, a pump shaft, an impeller and a generator set, the generator setcomprises a generator body, and the elbow-shaped water inlet channel is communicated with the siphon-type water outlet channel, one end of the pump shaft extends into the elbow-shaped water inlet channel and is in transmission connection with the hub of the impeller, and the other end extends out of the elbow-shaped water inlet channel and is in transmission connection with the main shaft of the generator body, the vertical axial flow pump further comprises a blade angle adjusting device; the blade angle adjusting device comprises a large gear having the gear shaft relatively fixed and connected to the hub, and a pinion meshed with the large gear, the small gears and the blades of the impeller are arranged in a one-to-one correspondence mode, and are fixedly connected with the corresponding blades. According to the invention, the impeller drives the pump shaft to rotate through the water flow impacting on the impeller, so that the main shaft of the generator body is driven to carry outreverse power generation, the angle of the blades is adjusted through meshing of the large gear and the pinion, and the precision of the blade adjusting angle is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic generators, in particular to a vertical axial flow pump. Background technique: [0002] The main function of the pumping station is flood control and drainage, and some pumping stations can generate electricity in reverse, creating direct economic benefits. The specific speed of the axial flow pump is relatively large, and its blades are adjustable to adjust the flow according to different working conditions. When the vertical axial flow pump is operating as a turbine for reverse power generation, the blades can be adjusted to different angles to improve the operating efficiency of the turbine. [0003] The Chinese patent with the application number 201721128395.9 discloses a new type of axial flow pump. Although this scheme has modified the axial flow pump, it is not suitable for the reverse power generation condition of the water pump, and cannot accurately adjust the blades in the axial flow...
