Characteristics Variables of Hydraulic Turbo-machines Apparatus Model FM 104
Characteristics Variables of Hydraulic Turbo-machines Apparatus Model FM 104
Sci-tech Characteristics Variables of Hydraulic Turbo-machines Apparatus Model FM 104 can be used to investigate a centrifugal pump. Experiments can be performed on two key water turbine designs: Pelton, Francis and Kaplan turbine, available as accessories.
The closed water circuit comprises a tank, a standard centrifugal pump with variable speed and a flow control valve to adjust the back pressure.
The speed is detected contact-free by means of an inductive displacement sensor on the motor shaft. To determine the drive power, the drive motor is mounted on swivel bearings and equipped with a force sensor to measure the drive torque. Pressures at the inlet and outlet of the pump are measured. The flow rate is measured by means of an electromagnetic flow meter. The measured values are displayed digitally and processed further by ‘Sci-Cal’ DAQ interface in LabVIEW. It is used to calculate the power output data of the examined turbo-machine and to represent them in characteristics

Turbo-machines such as pumps and turbines are energy converters. Turbines convert flow energy into mechanical energy and pumps convert mechanical energy into flow energy.

It is used to calculate the power output data of the examined turbo-machine and to represent them in characteristics.
One of the turbines Pelton, Francis or Kaplan turbine can also be placed on top of the storage tank. The centrifugal pump supplies the turbine with water. The measured values of the turbine are transferred via cable to turbine. A special feature of FM 104 is the ability to operate pump and turbine at the same time. Relevant measured values are recorded contemporaneously at both turbo-machines. Thus, the trainer can be used as a pumped storage plant.
