Energy conversion in a wind power plant. Wind power drive train. Wave energy converter, OWC. Gas turbine with power turbine. Simulation of a gas turbine. Simulation of a two-shaft system with power turbine allows easy understanding of the operating properties. Gas turbine jet engine.

Operating principle of a Pelton turbine. Operating principle of a Francis turbine. Ed with an axial turbine. Experiments with a reaction turbine. Experiments with a Pelton turbine.

Base unit for turbines. Experiments with an action turbine. Pelton and Francis turbine. A characteristic of fans is the pressure ratio, which indicates the ratio of the absolute final pressure to the absolute intake pressure.

Fans are different turbomaachines compressors because of their re pressure ratio of max. Experiments with a radial fan. Experiments with an axial fan.

Experiments with a radial compressor. Characteristic variables of a radial fan. In centrifugal pumps the energy is transferred hydrodynamically. In the hydrodynamic transfer of energy the fluid is accelerated by the impeller of the centrifugal pump. Therefore, the impeller of the centrifugal pump has to move with high velocity and thus a high rotational speed. Series and parallel configuration of pumps. Characteristic variables of hydraulic turbomachines.

Determination of output and efficiency of turbines and pumps; demonstration of a pumped storage plant. Experiments with a centrifugal pump. Hydraulic circuit with centrifugal pump.

Pump characteristics for parallel and series configuration. Assembly and alignment of pumps and drives. Assembly stand for pumps.

Standard chemicals pump with magnetic clutch. Comparison of positive displacement machines and turbomachines. Centrifugal pump, standard design. Centrifugal pumps, series and parallel connected. Investigation of the pump characteristic of series and parallel configurations of two centrifugal pumps. Understanding design and function of the pump; planning and executing assembly, disassembly and maintenance.

Axial-flow pumps are also turbomachinex as propeller pumps. Axial-flow pumps come with fixed blades and with variable blades. The flow passes through the impeller in axial direction. In axial-flow pumps, the pressure is not built up by the effect of centrifugal force but, like the aerodynamic principle, by the propeller blade.

Engineering animations such as cutaway models are ideally suited to representing processes turbomaxhines functions. GUNT uses up-to-date original parts for its cutaway models. Movement and switching functions are maintained. The GUNT team will be glad to support you. Service performances In addition to our range of equipment we offer training courses and commissioning of the equipment as well as assistance in laboratory planning.
