Product overview This water turbine teaching model demonstrates the structure and working principle of a simple hydraulic turbine and explains how flowing water is converted into mechanical work. The model includes a water tank, water guide, impeller, transmission shaft, casing transmission wheel, rubber plugs, and feet. It is designed for tabletop demonstration and hands on teaching. Key benefits Clear visual demonstration of energy conversion: flowing water hits the impeller and drives the transmission shaft, illustrating how hydraulic energy converts to rotational mechanical energy. Hands on learning and simple setup: assemble the model, place it in a larger sink or basin, fill with clean water, and remove the rubber plug to start the demonstration. Versatile teaching tool: useful for physics and mechanical education, laboratory experiments, classroom demonstrations, science fairs, and desktop display or gift presentation. Component level explanation: the included parts let instructors point out and explain the role of the water tank, water guide, impeller, shaft, and casing transmission wheel in turbine operation. Function and working principle Structure: the model consists of a water tank that feeds water through a water guide onto the impeller. The impeller is mounted on a transmission shaft connected to a casing transmission wheel. Rubber plugs seal the tank when needed and feet keep the model stable during operation. Operation: when water flows out of the tank through the guide, it strikes the impeller blades. The impact and flow of water cause the impeller to rotate. Rotation is transmitted through the shaft to the transmission wheel, demonstrating how flowing water can drive a mechanical load. Educational focus: the model makes it easy to observe blade interaction with water, rotational movement, and basic transmission of mechanical power. It also helps explain concepts such as flow direction, impulse or reaction on turbine blades, and energy conversion efficiency in a classroom setting. Compatibility and performance Intended use: designed for tabletop demonstration in sinks, basins, or shallow vessels that can hold enough clean water for continuous flow. Performance capability: the model shows visible rotation of the impeller and transmission wheel when water flows; it can be used to drive small demonstration loads to illustrate work output and conversion principles. Key parts: includes rubber plugs and feet for sealing and stability. The set is supplied as a model to assemble before use. Practical applications and scenarios Classroom demonstration: a physics teacher assembles the model on a sink to show students the parts of a turbine and how water causes rotation, reinforcing lessons on energy transformation. Laboratory experiment: students test how changing water flow or guide orientation affects impeller speed and observable work on the transmission wheel, supporting quantitative and qualitative study. Science fair or desktop display: the working model provides an engaging visual aid for presenting fundamental mechanical and hydraulic principles to an audience.
