Description

The experimental unit TVP 020 consists of the impeller, a needle nozzle used as control device, a band brake for loading the turbine and a housing with a transparent front panel. The transparent cover enables to observe the water flow, the impeller and the nozzle during operation. The nozzle cross-section and thus the flow rate are modified by adjusting the nozzle needle. 

The turbine torque is determined by force measurement on a band brake and is read on spring balances. For measuring the rotational speed, a non-contact speed sensor. A manometer shows the water pressure at the turbine inlet.

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

The materials used are resistant to corrosion. This gives it great strength and a flexibility of integration into your laboratory.

The manufacture of this equipment complies with the European standard for machinery manufacturing
