Types of Micro-Hydraulic Turbines

Types of Micro-Hydraulic Turbines

Based on their design and operating principles, micro-hydraulic turbines are mainly divided into the following common types:

1. Pelton Turbine

Principle: Uses the kinetic energy of the water flow to impact the turbine, causing it to rotate.

Features: Suitable for environments with fast water flows, typically used in small rivers or streams.

2. Turbine Turbine

Principle: Water flows through the turbine, driving the turbine blades to rotate.

Features: High efficiency, suitable for locations with large water flows and moderate flow velocities, commonly found in small hydropower stations.

3. Axial Flow Turbine

Principle: Water flows along the axis, driving the blades to rotate.

Features: Suitable for locations with large water flows and low flow velocities, typically used in low-head water sources.

4. Francis Turbine

Principle: Combining the characteristics of axial and radial flow, the water flows both along the axis and with some radial flow.

Features: Suitable for a variety of water flow conditions, with good adaptability. 5. Pelton Wheel

Principle: Utilizes the impact force of the water flow, which is ejected through a nozzle onto the cup-shaped blades of the water wheel.

Features: Suitable for locations with high drop heights and fast water flows, it offers high efficiency and a compact footprint.

6. Water Wheel

Principle: The water flow directly pushes the blades of the water wheel, rotating it.

Features: Traditional design, suitable for small water flows, commonly found in historical sites and small farms.

Selection Recommendations: Water Flow Conditions: Select the appropriate water turbine type based on the actual water flow and velocity.

Installation Environment: Consider the space and drop height of the installation site to select the appropriate design.

By understanding these types, users can select the most suitable micro-hydraulic turbine for their specific needs and achieve efficient hydropower generation.
