Understanding Pelton Wheel Turbines
What is a Pelton Wheel Turbine?
The Pelton wheel turbine is an impulse-type turbine that operates on the principle of converting the kinetic energy of water into mechanical energy. Water is directed through nozzles at high speed, striking the buckets attached to the runner. This design allows Pelton turbines to achieve high efficiencies, especially in high-head situations.
Key Benefits of Pelton Wheel Turbines
- High Efficiency: Pelton turbines can maintain efficiencies of over 90%, making them optimal for environments with significant water head.
- Durability: Constructed from robust materials like stainless steel, Pelton turbines offer longevity and resistance to wear.
- Minimal Civil Works: Pelton turbines require less infrastructure compared to other turbine types, reducing installation costs.
- Versatility: They can be tailored to meet specific site conditions, including variations in head and flow rate.
