Francis Turbine Test Setup
Product Code : EL-HML-11051
Quick Answer: Francis Turbine Test Setup is a mixed flow reaction turbine rig in which water enters the runner radially and leaves axially, with a brake arrangement for calculating turbine efficiency. It comes in 1.33 HP, 2 HP and 5 HP versions with a curved-vane runner, guide mechanism, draught tube and rope brake dynamometer.

Key Features
- Runner with curved vanes on an SS shaft, supported by a thick cast iron pedestal
- Water fed radially to the runner by a centrifugal pump
- Guide mechanism, with a draught tube at the outlet
- Pressure and vacuum gauges at inlet and outlet for the total supply head
- Transparent acrylic window in the casing for watching flow onto the runner
- Control panel with star/delta starter, mains indicator and MCB for overload protection

About This Product
The runner sits in an air-tight casing that is always full of water, and part of the pressure energy changes into kinetic energy as water passes through, so the flow through the runner stays under pressure. Students apply load with the brake arrangement and read the inlet and outlet gauges to calculate efficiency, an exercise on reaction turbines in the HYDRAULIC MACHINE LAB.
Frequently Asked Questions
Q1. Why is it called a mixed flow turbine?
Water enters the runner through its outer periphery in the radial direction and leaves the runner in the axial direction.
Q2. How is the total head on the turbine measured?
Pressure and vacuum gauges fitted at the inlet and outlet of the turbine measure the total supply head.
