About Water Turbines
Water turbines are machines designed to convert the kinetic and potential energy of flowing or falling water into mechanical energy. They are a crucial component in hydropower plants, irrigation systems, and various industrial processes.
Types of Water Turbines
- Impulse Turbines
- Description: Operate by directing high-speed water jets onto the turbine blades. The energy is imparted to the blades through the impact of the water.
- Examples: Pelton turbines, Turgo turbines.
- Applications: Suitable for high-head (high-pressure) sites with low to moderate flow rates.
- Reaction Turbines
- Description: Use the reaction force of water flowing over the turbine blades. The water pressure decreases as it moves through the turbine, and both kinetic and pressure energy are converted into mechanical energy.
- Examples: Francis turbines, Kaplan turbines.
- Applications: Ideal for low to medium head sites with high flow rates.
- Axial Flow Turbines
- Description: Feature blades that are oriented parallel to the flow of water. The water flows through the turbine in the same direction as the rotor shaft.
- Examples: Kaplan turbines.
- Applications: Best suited for low-head applications with high flow rates.
- Crossflow Turbines
- Description: Water flows through the turbine in a crosswise direction relative to the rotor shaft. The design allows for the effective use of water at lower heads.
- Examples: Crossflow turbines.
- Applications: Used in small-scale hydropower projects and low-head sites.
Key Parts of Water Turbines
- Runner (Impeller)
- Description: The component that converts the energy of the water into mechanical energy through rotation. It consists of blades or buckets that capture the water’s energy.
- Nozzle
- Description: Directs the flow of water onto the turbine runner. In impulse turbines, nozzles create high-velocity jets of water.
- Guide Vanes
- Description: Positioned before the runner to direct the flow of water onto the blades in the desired direction.
- Draft Tube
- Description: A conduit that channels the water flow from the runner to the tailrace or downstream. It helps recover some of the pressure energy from the water.
- Bearing System
- Description: Supports the turbine shaft and allows it to rotate smoothly. Includes both radial and thrust bearings to handle different types of loads.
- Governing System
- Description: Regulates the turbine’s speed and power output. It includes mechanisms such as wicket gates or blade pitch adjustment systems.
- Shaft
- Description: Transmits the mechanical energy from the runner to the generator or other machinery. It must be robust and precisely aligned.
- Casing
- Description: The housing that encloses the turbine components and directs the water flow through the turbine. It provides structural support and protection.
- Seals
- Description: Prevent leakage of water and ensure the proper functioning of the turbine. Includes various types such as shaft seals and gland seals.
- Control System
- Description: Monitors and controls the operation of the turbine, including speed regulation, load management, and safety functions.
