  Piston Pump Demonstrator

  The demonstration unit enables the pump curve of a reciprocating pump to be measured. The system consists of the pump with an electrical drive motor, the pipe system with supply tank and a container for volumetric flow measurement. Electronic sensors provide the delivery pressure and the pressure in the cylinder; a position sensor is used to determine the position of the connecting rod and thus the volumetric displacement. The pressure level in the system is maintained constant using a pressure retention valve. The pulsating pressure characteristic of the pump can be damped with an air vessel. The following accessories are required for operation: an Interface Module , Data Acquisition Card with Software and a Set of Connecting Cables . This layout makes it possible to record measured values during the experiments, and process and store this data on a PC.

  Radial-Flow Reaction Turbine Demonstrator

  Technical Description Reaction turbine demonstration unit, designed for operation in conjunction with the Turbine Service Unit. The turbine unit is placed on the Turbine Service Unit and supplied with water by the service unit. The turbine housing is made of Plexiglass so that the emerging water jet that drives rotor using the reaction principle can be observed unhindered. A braking device is fitted to the impeller shaft of the turbine, the braking device is in the form of a band brake using which the load and moment on the turbine shaft can be measured with an electronic dynamometer. A proximity switch measures the rotational speed of the turbine. The following accessories are required for operation: an Interface Module , Data Acquisition Card with Software and Connecting Cables . Using these accessories it is possible to take measurements, and process and store the measurements on a PC.

  Turbine Demonstrator Supply Module

  The supplies the turbine models with water. It consists of a supply tank, pump and pipe work; these are mounted in clear layout on a base plate. The turbine models are placed on the supply tank and bolted in place. A hose provides the connection for the pressure line to the turbine model. After flowing through the turbine, the water flows directly into the supply tank. The flow rate and the pressure present at the turbine can be adjusted using a control valve. Electronic sensors measure the flow rate and supply pressure. The following accessories are required for operation: an Interface Module, Data Acquisition Card + Software and Connecting Cables . These accessories enable to process and store the measured data on PC.

  Series And Parallel Pump Demonstrator

  The demonstration unit facilitates the measurement of pump curves in various operating modes. The unit comprises 2 identical centrifugal pumps that are connected together via a system of pipes. Shut off valves permit the pumps to be operated in series or in parallel. Electronic sensors provide relevant pressures, the temperature of the pumped medium, and the rotational speed of the drive motors are measured values. The flow rate of the pumps can be adjusted using power adjusters. The following accessories are required for operation: an Interface Module , Data Acquisition Card with Software and a Set of Connecting Cables . This layout makes it possible to record measured values during the experiments, and process and store this data on a PC. Power Meters are a practical way to expand the unit.
