Francis Turbine Demo Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14131

The Francis Turbine Test Rig is an experimental apparatus designed to study the operation and performance characteristics of a typical single-stage Francis turbine. The Francis turbine is a radial flow reaction turbine widely used in hydroelectric power plants for medium heads (typically 15m to 300m) and medium volume flow rates. It operates by transferring water energy to the runner through changes in both velocity and pressure.

The unit is a self-contained, re-circulating system with a sump tank and a centrifugal pump to supply water. Key features include:

Horizontal Axis Turbine: Mounted on a robust, mobile frame.
Inlet Control: Flow rate and head are regulated by a hand-operated inlet valve and measured by a pressure gauge and a variable area flow meter.
Flow Guidance: Water enters the runner through stationary guide vanes. The flow rate and water angle of incidence are controlled by a ring mechanism that varies the position of these guide vanes.
Power Measurement: The developed torque is measured using load cells connected to a disc brake dynamometer (High Capacity Model uses a band brake with a load cell).
Speed Measurement: Turbine shaft speed is measured using a digital tachometer.
Observation: A transparent observation window allows students to view the operation of the inlet guide vane mechanism.
