Integrated reversed fixed-pitch tubular hydraulic generator

Abstract

The invention discloses an integrated reversed fixed-pitch tubular hydraulic generator which comprises a rotor mechanism, a stator mechanism, a runner mechanism, a guide vane mechanism, a water inlet pipe and an exhaust water pipe. The stator mechanism and the rotor mechanism are coaxial. The stator mechanism is located on the inner side of the rotor mechanism. The guide vane mechanism is fixedly installed in front of the rotor mechanism. The water inlet pipe is located in front of the guide vane mechanism. The exhaust water pipe is located behind the rotor mechanism. According to the integrated reversed fixed-pitch tubular hydraulic generator, no ventilation system or cooling water system is needed, the quantity of required consumables is small, the universality is good, the size is small, the material requirement is low, and the service life is long.

Description

technical field [0001] The invention relates to the field of hydropower equipment, in particular to an integrated reverse-mounted fixed-blade tubular hydroelectric generator. Background technique [0002] According to the working principle, water turbines can be divided into two categories: impact turbines and impact turbines. [0003] The runner of the impact turbine rotates under the impact of the water flow, and the pressure of the water flow remains unchanged during the working process, mainly due to the conversion of kinetic energy; [0004] The runner of the impact turbine is rotated by the reaction force of the water flow in the water, and the pressure energy and kinetic energy of the water flow are changed during the working process, but mainly the conversion of the pressure energy. [0005] Pelton turbines can be divided into two types according to the flow direction of the water flow: the cutting type (also known as the water bucket type) and the oblique type. ...

Problems solved by technology

[0010] Existing tubular water turbines are all connected to the generator through the main shaft, so as to drive the generator rotor to rotate and cut the magnetic force line to generate electricity. The structure of the turbine and the generator requires at least three bearings, and some models also need to use complex structures and expensive bearings. servomotor

[0011] Moreover, the existing hydraulic generators need to design a ventilation system to dissipate heat from the generator, design a seal, and require a cooling water system to dissipate heat from the generator, requiring at least one thrust point, multiple bearings, stators, rotors, and salient poles, which require high material strength , the rotor temperature cannot be measured in real time, and each group of hydro-generators is a customized machine for different terrains, resulting in raw materials, components, wires and parts that cannot be used in common use, and cannot be mass-produced. The series connection structure of the machine and the exciter results in a huge volume and requires a lot of materials, which directly results in high cost

The capacity cannot be adjusted arbitrarily when the shell remains the same
