Advantages:
- Buckets: Each bucket has a symmetrical double groove spoon shape with a splitter in the middle. When high-speed water flows through the nozzle and impacts the bucket blade, the water splitter evenly divides the water flow into two streams, symmetrically flowing along the groove of the bucket blade, reducing vibration and improving efficiency.
- Wheel material: Made of high-strength PP material to withstand the impact and wear of high-speed water flow under high water head.
- Installation method: The buckets are fixed to the impeller disc with bolts, forming a uniformly distributed impeller structure in the circumferential direction.
- High energy conversion efficiency: The bucket design almost completely converts the kinetic energy of water flow into mechanical energy, with an efficiency of over 90% (especially suitable for high water heads).
- Anti cavitation and wear: The symmetrical diversion design of the bucket blades reduces local force concentration, and high-strength materials can resist the impact wear of high-speed water flow and sediment.
- Flexible adjustment: By adjusting the nozzle opening or using a multi nozzle design, the water flow can be flexibly controlled to adapt to changes in load.
- Low maintenance requirements: The structure is simple, and the bucket can be replaced separately, resulting in low maintenance costs.

Working Principle:
- High speed jet impact: High pressure water flows through the nozzle to form a high-speed jet (with a speed of over 100m/s), which directly impacts the bucket blades on the impeller. The kinetic energy of the water flow is converted into the rotational mechanical energy of the impeller, which drives the generator to generate electricity.
- Energy release process: After the water flows into the bucket blade, it flows out almost 180 degrees in the opposite direction along the bucket groove, and the kinetic energy is fully absorbed. The water flow eventually leaves the impeller at a speed close to zero.
