The innovative and environmentally-friendly water turbine system introduced by Shanghai can minimize the impact of environmental protection on hydropower development, maintain ecological balance, and improve the mechanical performance of hydropower generation systems and improve economic efficiency. The innovative environmentally-friendly water turbine system is designed to reduce the downstream water quality by using the “upward free water†design to eliminate liquid flow cavitation, blade vibration and high-pressure shaft sealing.
The upward-diffusing rotor passage allows the tailwater kinetic energy to be recovered without the draft tube. The use of a drum-shaped needle valve to control flow (instead of a conventional vane shutter) simplifies the flow control mechanism and operating procedures, reducing damage to fish. The modular assembly has resulted in a considerable reduction in equipment cost, assembly time, maintenance requirements, and power plant construction time and cost of the new turbine. Especially suitable for the development of small and medium-sized, and micro-hydropower.
According to the Shanghai Intellectual Property Service Center, the invention has successfully carried out model experiments at Iowa State University and Tsinghua University in China, and optimized the prototype design using fluid dynamics calculation (CFD) to achieve high efficiency. Running.
