Description

The FM6X Turbine Service unit provides a pressurised high flow water supply, which is required to operate the FM60, FM61 and FM62 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.

The dynamometer unit also incorporates an optical sensor, which measures the rotational speed of the turbine.

Demonstration Capabilities

• Determining the characteristics of the selected turbine, including the relationships of volume flow rate, head, torque produced, power output and efficiency to rotational speed (FM60/FM61/FM62)
• Comparison of nozzle and throttling control of an Impulse Turbine (FM60)
• Comparison of throttle control and spear valve control of the speed of a Pelton Turbine (FM62)
• Determination of characteristic performance curves for a peripheral pump, including constant speed head/flow and efficiency curves (FM64)
