Elbow pipe runner and multi-nozzle water turbine thereof

Abstract

The invention discloses an elbow pipe runner, and further discloses a multi-nozzle water turbine with the elbow pipe runner. The elbow pipe runner comprises a ring-shaped runner shell, a circular inner drum plate with shaft holes sleeved with the runner shell and a plurality of elbow pipes; the runner shell is coaxial with the inner drum plate; each elbow pipe includes a water inlet section and awater outlet section; the plurality of elbow pipes are uniformly and fixedly arranged between the runner shell and the inner drum plate at the same angle with the vertical direction; water inlets of the plurality of elbow pipe water inlet sections are arranged in the same direction along the loop line, wherein the plurality of elbow pipes are located at the loop line; the water inlet sections of the elbow pipes are arranged at the upper portion of the water outlet sections; and both the water inlet sections and the water outlet sections of the elbow pipes are arranged obliquely. The runner andthe water turbine thereof have simple structures, the whole machine occupies a small area, has high adaptability, and is suitable for a waterhead of 10 m or above; and most of water flows of the elbow pipe multi-nozzle water turbine can do repeated impact work with different times, so that the working efficiency is improved, and the electric energy conversion rate is high.

Description

technical field [0001] The invention relates to an elbow type runner and a multi-nozzle water turbine thereof, belonging to the technical field of hydraulic power generation machinery. Background technique [0002] With the development of global industrialization, people's living standards are constantly improving, and energy problems are gradually becoming prominent. The development of clean and renewable energy is an inevitable trend of human development needs. High-quality water turbines are economical and can make good use of limited hydraulic resources. They are the best way for people to solve the problem of electricity consumption. [0003] Pelton turbines currently on the market are divided into bucket type, oblique impact type and double-click type, each of which has its own shortcomings, such as low efficiency and limited adaptability. The double-click turbine impacts the upper blades first, and then acts on the lower blades of the runner for secondary energy exch...
