Pelton turbine with spiral nozzles

Abstract

The invention discloses a Pelton turbine with spiral nozzles. According to the Pelton turbine with the spiral nozzles, spiral teeth are evenly distributed on the circumference of a rotating wheel, thenumber of the spiral teeth is more than 5, the spiral teeth are uniformly distributed by taking the axis of the rotating wheel as the center, the spiral teeth are spirally lifted around the axis of the rotating wheel, and upstream faces of the spiral teeth are concave arc-shaped; the spiral nozzles are uniformly distributed on the circumference of the inner ring of a volute, and the number of thespiral nozzles is more than two, the number spraying interface of each spiral nozzle is more than or equal to one, and a three-dimensional spraying space is formed by more than two spiral nozzles anda rotating wheel matched with the spiral nozzles in thickness; and the length-width ratio of each spiral nozzle is larger than 3. According to the working method, water flows into the volute from a water inlet, the water in the volute is sprayed out in the directions of the tangent lines of the positions, where the spiral nozzles are opposite to the rotating wheel, of the spiral nozzles, and thesprayed water is directly sprayed on the concave arc-shaped faces of the upstream faces of the spiral teeth to push the rotating wheel to rotate.

Description

technical field [0001] The invention relates to a cutting water turbine, in particular to a "cutting water turbine with a spiral linear nozzle", which belongs to a fluid machine and is mainly used for power generation of water reservoirs and dams. Background technique [0002] Chinese patent application number: 201610025445.4, "Vertical Shaft Multi-Stage Impulse Turbine". The chamber is connected to the tailrace channel, and the main shaft of the turbine passes through each runner chamber in turn from top to bottom, and corresponding to each runner chamber, a vertical shaft water bucket runner is set on the main shaft of the turbine, and each runner chamber is set to surround the chamber The water distribution ring pipe of the chamber, the water distribution ring pipe is connected with the water inlet pipe, and a number of nozzles and spray needles are evenly connected to the water distribution ring pipe. Bucket wheel arrangement. This patent application is three-dimension...

Problems solved by technology

This patent application is three-dimensional, and the runners are arranged in three-dimensional space. The nozzle can only be regarded as a point, and the complexity of the structure has increased significantly. A three-dimensional drive can also be realized with a runner.
