Aha obi, ọnụọgụ pipe material dị ka ọ dị ka ọbụla maka ụfọdụ ụzọ uwa, ọ bụrụ na ọ bụ long thin pipe, ma ọ bụ short wide pipe. Pelton wheels na-ekwu n'ọnụọgụ isi. Enweghị multi-ton Pelton wheels mounted on vertical oil pad bearings n'ụlọ oyi na hydroelectric. Ndị isi karịa enweghị ikpe azụ 200 megawatts. Ndị isi karịa Pelton wheels enweghị azụ ọ bụla inches, na-enweghị ike ịkpata ike maka ụzọ uwa na mountains nwere mgbakwunye uwa dị ka ọ bụ gallons per minute.

Ọmụmaatụ

• High-Head Dedicated Design: Specifically suited for water sources with high heads (typically ≥100 meters, and some models can handle several thousand meters) and low flow rates. It efficiently converts the potential energy of water into kinetic energy, and its efficiency is significantly higher than other turbine types in high-drop scenarios.
• Impulse-Type Energy Conversion: Converts high-pressure water flow into high-speed jets through nozzles, which directly impact the bucket-shaped blades on the runner. The water flow only contacts the blade surfaces (without filling the flow channel), and the energy conversion process is concentrated at the "impact moment", resulting in clearer structural stress.
• Low Water Quality Requirement: Since the water flow does not pass through complex flow channels (such as volutes and guide vanes), it is less likely to suffer internal blockages or wear caused by sediment and impurities in the water. It has a longer maintenance cycle and is suitable for water sources with relatively complex water quality, such as those in mountainous areas.
• Flexible Output Regulation: Can achieve stepped or continuous regulation of unit output by increasing or decreasing the number of nozzles in operation (e.g., 2-nozzle, 4-nozzle models) or adjusting the jet diameter of individual nozzles, adapting to the fluctuation needs of grid load.
• Simple Structure & Easy Maintenance: Core components only include nozzles, runners, and casings, without complex water guiding mechanisms (such as the guide vanes of reaction turbines). It has low installation difficulty, and daily maintenance mainly focuses on nozzle wear and runner cleaning, with controllable costs.
