The Multi Turbine Test Rig is designed to be a self-contained unit to demonstrate the operation and performance characteristics of three types of turbines, namely Francis (radial flow) turbine, Kaplan (axial) turbine, and Pelton (impulse) turbine. The turbines will be driven by a 3kWpump and comes complete with dynamometer. The Multi Turbine Test Rig is capable of performing experiments on mechanical power, hydraulic power, hydraulic efficiency, and specific speed.
The Multi Turbine Test Rig consists of a centrifugal pump with controlled motor speed, three interchangeable sets of Pelton, Francis, and Kaplan
turbine complete with individual casing respectively. The test set is a self contained unit comprising two main assemblies; an instrument / control console and a welded steel base frame, which carries the pump, turbine set, and water reservoir tank.
In terms of the functionality, an inverter with speed dial controls the centrifugal pump motor speed in between 0 to approximately 3000 rpm. Power transducer is provided to measure the power consumption of the pump motor. Speed sensors are installed on both pump and DC generator shaft to measure the rotational speed of the motors. Load cell is mounted beneath each motor. The torque arm is directly depressing against the load cell arm, there by compressing against the motion.
With the aid of the torque sensor, we can register and detect the torque or force acting on the motors. A volt meter and an ampere meter are provided to measure volt and current generated by the DC generator. Pressure transmitters are installed on each inlet and outlet of both pump and turbine set to measure the pressure on the respective locations.
Five sets of Resistor banks are installed to provide necessary load to the DC generator during experiment.
Software TH-3138SW (optional)
DAQ software specially designed in National Instrument™, LABVIEW™ environment to measure and calculate the results of apparatus. The software is optional and while using software a set of electronic sensors are included. Software can be run with any Windows™ environment.
