Hydraulic turbo wheel and working method thereof

Abstract

The invention discloses a hydraulic turbo wheel. The hydraulic turbo wheel comprises a wheel disc, blades, blade angles and a center disc, wherein the center disc is arranged in the middle of the wheel disc, the center disc is connected with an output shaft, the multiple uniformly distributed blades are arranged on the outer ring of the center disc, and the end, close to the center disc, of each blade is connected with a blade angle. The hydraulic turbo wheel can solves the problems that when an existing hydraulic turbo wheel is in use, because the impact area is small when blades of the wheelmake contact with fluid, the conversion of fluid impact cannot be converted to mechanical energy to the maximum extent; and flow guide blades and wheel inlets can be designed to be equal in width through the wheel inlets so as to realize the flow passing through a flow director and the flow passing through the wheel to keep equal and realize the effect of the maximum flow of the flow director onthe fluid, but each wheel inlet of a linear structure is ignored, the loss of energy occurs when the fluid is input and vertically collides with the inner wall of the wheel inlets, and the energy conversion efficiency is reduced.

Description

technical field [0001] The invention relates to the field of hydraulic turbine impellers, in particular to a hydraulic turbine impeller and a working method thereof. Background technique [0002] A hydraulic turbine is an energy recovery device, and a turbine is a machine that converts the energy contained in a fluid working medium into mechanical energy, also known as a turbine. The working conditions of the turbine and the working fluid used are different, so its structure is various, but the basic working principle is similar. The most important part of a turbine is a rotating element, the rotor, or impeller, which is mounted on the turbine shaft and has uniformly arranged blades along the circumference. The energy possessed by the fluid is converted into kinetic energy when passing through the nozzle in the flow, and when the fluid flows through the impeller, the fluid impacts the blades and pushes the impeller to rotate, thereby driving the turbine shaft to rotate.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a hydraulic turbine impeller and its working method, which can solve the problem that the blades of the impeller cannot maximally impact the fluid during the use of the existing hydraulic turbine impeller. The force is converted into mechanical energy because the impact area of ​​the blades of the impeller in contact with the fluid is small. Secondly, although the impeller inlet can be designed to have the same width as the guide vane and the impeller inlet, the flow through the deflector and the flow through the impeller The flow rate is kept equal to achieve the maximum diversion effect of the deflector on the fluid. However, it ignores that the impeller inlet is a linear structure, so when the fluid is input, it will collide with the inner wall of the impeller inlet vertically to cause energy loss. thus reducing the energy conversion efficiency
