HM 289 Experiments with a Pelton turbine

GUNT HM 289

Pelton Turbine is an experimental unit designed for mounting on the HM 290 base unit, allowing detailed studies of the operation and performance characteristics of a Pelton turbine.

The transparent housing enables direct observation of the Pelton wheel and adjustable needle nozzle, allowing modifications of the nozzle cross-section. The turbine operates at a constant pressure, simulating real-world conditions, with the pressure being adjustable via HM 290. A wear-free eddy current brake is used to apply load to the turbine. Measurements include torque via a force sensor and speed via an optical sensor.

Water supply, flow rate measurement, and software-based data acquisition are all managed through the HM 290 base unit. This experimental setup provides a hands-on experience in studying hydraulic energy conversion and turbine performance, making it an ideal educational tool for technical training and research in fluid mechanics and hydraulic engineering.
