Hydraulic turbomachines are a type of fluid energy machine. They work continuously and feature a steady pressure difference between inlet and outlet. HM 450C is a modular trainer for basic experiments in the field of hydraulic turbomachines. HM 450C forms the base unit. A centrifugal pump is included, which is used to conduct experiments on the topic of work machines. A closed water circuit means the trainer can be used anywhere.

The trainer is equipped with all major sensors for data acquisitions in order to ensure meaningful results. Key measuring values are displayed during the experiments on displays on the trainer and on a PC.

Measurement analyses such as dimensionless parame-ters and pump characteristics can be displayed and saved on a PC using the GUNT software.

A special feature of HM 450C is the ability to operate pump and turbine at the same time. Relevant measured values are recorded contemporaneously at both turbomachines. Thus the trainer can be used as a pumped storage plant.

The Pelton turbine HM 450.01 and Francis turbine HM 450.02 offer an expansion to the range of experiments on the topic of power engines. The two turbines are easy

to install on the trainer. They are connected with handles on the delivery side of the centrifugal pump. The sensors are connected via plugs on the trainer’s switch cabinet.
