Turbine Service Unit
Description:
The Turbine Service unit provides a pressurised high flow water supply, which is required to operate the turbine demonstration modules.
The turbine under test is connected to the dynamometer by a toothed drive belt.
Load is applied to the turbine using a magnetic brake controlled directly from the computer.
The outer casing of the brake is restrained from rotating by a lever arm, which is connected to a load cell. This enables the braking force and the torque produced to be directly measured.
Features:
- Determining the characteristics of the selected turbine, including the relationships of volume flow rate, head, torque produced, power output and efficiency to rotational speed
- Comparison of nozzle and throttling control of an Impulse Turbine
- Comparison of throttle control and spear valve control of the speed of a Pelton Turbine
- Determination of characteristic performance curves for a peripheral pump, including constant speed head/flow and efficiency curves
