Abstract

The invention discloses a horizontal type flush efficient excitation adjustable-pitch axial flow hydraulic generator and an acting method thereof. The horizontal type flush efficient excitation adjustable-pitch axial flow hydraulic generator comprises a power generating mechanism, an excitation mechanism, a runner mechanism, an exhaust water pipe, a water guiding mechanism and a runner chamber. The runner mechanism comprises rotary blades, a rotary inner cover and a fixed outer cover. The rotary blades are distributed on the inner side of the rotary inner cover in a fan-shaped mode. The rotary inner cover and the fixed outer cover are connected through a sealing bearing to form a sealed annular cavity. The excitation mechanism and the power generating mechanism are coaxially installed in the annular cavity in an inside-outside mode side by side. A sealed water flow channel is formed by the water guiding mechanism, the runner chamber and the exhaust water pipe. The horizontal type flush efficient excitation adjustable-pitch axial flow hydraulic generator is long in service life, low in construction cost and production management cost and high in hydraulic energy conversion efficiency.

Description

technical field [0001] The invention relates to the field of hydropower equipment, in particular to a horizontal flat-mounted high-efficiency excitation paddle axial-flow hydroelectric generator and a method for doing work. Background technique [0002] According to the working principle, hydroelectric power generation devices can be divided into two categories: impact turbines and impact turbines. The runner of the impact turbine is impacted by the water flow and rotates, and the pressure of the water flow remains unchanged during the working process, mainly due to the conversion of kinetic energy; the runner of the impact turbine is rotated by the reaction force of the water flow, and the pressure of the water flow during the working process Both energy and kinetic energy are changed, but mainly the conversion of pressure energy. [0003] Pelton turbines, because only part of the working wheels pass through the water, and part of the water bucket is under force, so the re...
