1、 Basic information

1. Schematic diagram of the appearance of exhibits

2. Introduction to Exhibits

Exhibitions mainly consist of exhibition booths (marked 1), upper water tanks (marked 2), lower water tanks (marked 3), water pumps (marked 4), Pelton turbines (marked 5), Francis turbines (marked 6), Kaplan turbines (marked 7), water valves (marked 8), water pipes (marked 9), power meters (marked 10), etc. The sink is embedded in the exhibition booth and can be observed through a transparent acrylic window; Set up water level indicator lights on the countertop for easy observation. The audience repeatedly shakes the handle to draw water from the lower pool to the upper pool. When the highest water level is reached (or not), different water valves can be opened to direct the water flow into different turbines: Pelton turbine, Francis turbine, or Kaplan turbine, and their efficiency can be compared on the instrument.

3. Display purpose

exhibits showcase the working principles of hydroelectric power generation and three common types of water turbines through mechanical interaction.

4. Exhibition knowledge points

The basic principle of hydroelectric power generation is to use the water level drop to generate electricity in conjunction with a hydroelectric generator, that is, to convert the potential energy of water into the mechanical energy of the hydroelectric turbine, and then use the mechanical energy to drive the generator to obtain electricity.

Francis turbine, also known as mixed flow turbine, uses the pressure and kinetic energy of water flow to drive the concentric rotation of the blades on the shaft to do work. It is suitable for hydroelectric power plants with medium head and medium flow rate.

Pelton type water turbine, also known as bucket type water turbine, is a hydraulic prime mover with the centerline of the working jet tangent to the pitch circle of the impeller, and the impeller blades composed of a series of double bowl shaped water buckets. This type of water turbine is suitable for high head and low flow hydroelectric power plants.

The Kaplan turbine is a type of internal flow counterattack turbine with variable blade types, suitable for high flow, low head hydroelectric power plants.

5. Exhibition operation process

6. Notes

(1) All materials and parts must be made of waterproof and anti rust materials, such as stainless steel, ABS, etc;

(2) Transparent acrylic must undergo anti condensation treatment;

(3) The upper water tank needs to be designed with an anti overflow structure.
