Industrial gas turbine
Steam turbine
Turbine impellers usually work at high speed and can quickly convert fluid kinetic energy into mechanical energy. This enables turbine impellers to provide greater power output at a certain size.
Turbine impellers can be designed and optimized according to different working conditions and fluid media. Turbine impellers of different shapes, materials and blade angles can adapt to working environments with different flow rates, pressures and temperatures.
Modern turbine impellers adopt lightweight design, which achieves lightweight while maintaining sufficient strength and rigidity by reducing the amount of material used and optimizing the structural design.
Turbine impellers are usually made of high-strength, high-heat-resistant alloy materials, have good fatigue resistance and corrosion resistance, and can maintain stable operation under long-term high-speed rotation conditions.
