Description

The TVP010 bench allows the study of a hydraulic Pelton turbine

The user will adjust the supply of the various turbine parameters (pressure, flow rate and nozzle opening). It will then use the band brake in order to create a load on the turbine shaft.The goal is to vary the speed and to be able meet the diverse settings according to it.

The system is designed to allow the user to visualize the impact of the water on the blades of the turbine and to see the shape of the jet depending on the load on the shaft. Torque measurement using a digital dynamometer and masses of known weight. Students will have to make a calculation of mechanical conversion to obtain the torque.

The robust design of this device makes it suitable for use in schools.

Anodized aluminum structure on wheels gives it a very robust as well as a flexible integration into your premises.

The manufacturing of this equipment meets European Machine Directive
