HM 287

Axial-Flow Reaction Turbine Demonstrator

Technical Description

The HM 287 axial turbine represents a model of a reaction stage as found in gas and steam turbines. The model can be completely independently operated, as it is provided complete with a supply tank, pipework, pump and instrumentation on a laboratory trolley. The flow rate in the sealed water circuit is determined using a differential pressure measurement at a measuring orifice and can be adjusted using a ball-cock. The moment present on the turbine shaft is measured using a dynamometric brake with an electronic force sensor. In addition, the turbine speed is measured using an inductive proximity switch. The following accessories are required for operation: an Interface Module (HM 280.01), Data Acquisition Card with Software (HM 280.03) and Set of Connecting Cables (HM 280.04). Using these accessories it is possible to take measurements, and process and store the measurements on a PC.
