Abstract

The invention discloses a water turbine with multiple vanes. The water turbine comprises volutes, rotating wheels, a support cover, a bearing, a bottom ring and a drainage pipe. Nozzle rings are arranged in volute spiral runners and on the radial peripheries of the rotating wheels, orifices for jetting liquid flow to drive the rotating wheels are arranged on the nozzle rings at equal intervals, vanes are evenly arranged on the circumferences of the rotating wheels at equal intervals, and arc-shaped runners matched with the liquid flow jetted by the orifices are formed between the vanes. The runners of the water turbine with multiple vanes can convert not only kinetic energy of the liquid flow but also part of potential energy of the liquid flow; within a certain range of revolving speed, output power and flow are basically in a linear relationship, so that a complex adjustment and control system is not needed; and the structure of the water turbine is greatly simplified, the production process is simple and the cost is reduced. The water turbine is compact in structure, applicable to purposes such as small-size (miniature) hydroelectric generation and conversion from liquid dynamic energy to rotary mechanical energy in pipelines.

Description

technical field [0001] The invention belongs to the field of mechanical design and manufacture, in particular to the field of water turbine design and manufacture, and in particular to the runner and flow channel design technology of the water turbine. Background technique [0002] The existing impact water turbine is composed of a volute, a fixed guide vane, a water guide mechanism, a runner, a draft tube and other flow-passing components, and the potential energy of the water flow is converted by the runner. The number of blades of mixed flow runners is generally 13 to 17, and the number of blades of axial flow and tubular flow runners is generally 3 to 5. The blades are all sculptured curved surfaces, and the processing technology is complicated. Both the fixed guide vane and the movable guide vane are curved surface components. The surface of the bucket of the impact turbine runner is also a complex sculpture surface. [0003] When designing, the volute, water guiding ...
