HT 310 FRANCIS TURBINE TEST SET
GENERAL DESCRIPTION

The set is designed for studying the Francis turbine characteristics under various flow rates and heads.

The unit consists of a storage tank, a pump, a turbine, a dynamometer, a generator, and measuring instruments. The adjustable guide vanes direct water spirally to the runner. Power output at various flow rates, heads and speeds can be measured by either dynamometer or generator.

The unit is on wheels.

Instruction manual is also included.

TYPICAL EXPERIMENTS
  • Torque vs speed at various heads and flow rates.
  • Power output vs speed for various heads and flow rates.
  • Efficiency vs speed for a given head and flow rate.
  • Overall turbine generator efficiency.
  • Racing characteristics.
TECHNICAL DATA

 - Construction
  • Bronze runner, with adjustable guide vanes
  • Bronze casing with transparent cover to observe guide vane position
 - Ratings Over 1200 W of brake power or over 800 W of electrical power
Motor 7.5 kW
Generator 1.5 kW, 220 V, 1 Ph, 50 Hz.
Electrical load Lamp bank
Dynamometer Water cooled stainless steel mechanical brake with anti splashing system
Measuring instruments:
 - Torque Spring balance
 - Pressure Pressure gauge
 - Sensors with digital display
  • Voltage and current for electrical power output
  • Flow rate and speed
Software for data display and analysis by computer (separately supplied).
Power supply 380 V, 3 Ph, 50 Hz. Other power supply is available on request.
OPTIONAL EQUIPMENT
Part No. Part Name
HP 008 Advanced inverter for controlling and indicating motor speed as well as for calculating motor input power. Hence pump efficiency at various speeds can be determined.
HP 011A Pressure digital display instead of pressure gauge.
HP 012A Torque digital display instead of spring balance.
HD 200DA Water brake absorber dynamometer instead of mechanical brake dynamometer. In this case connection to the turbine with generator is by pulleys or direct coupling to the turbine without the generator.

Computer Interface

Sensors with computer interface unit for key data acquisition instead of analog
data measuring instruments.

This includes computer interface unit with torque and pressure sensors instead of spring balance and pressure gauge.
