Tourbo Machinery Laboratory Equipment


Model NO- TM-012


The “SUNLABTECH” designed and developed self-contained, mobile unit of multiple types of turbines including Pelton, Francis, Kaplan and/or Cross Flow. Designed for study of turbine characteristics under various flow rates and heads. Includes pump, storage tanks, turbine units connected in parallel, dynamometer for each turbine, and instrumentation for measuring flow rate, speed, and torque.

The speed is captured by means of an inductive, non-contact position sensor at the turbine shaft. For determining the turbine power, the eddy current brake is equipped with a force sensor for torque measurement. The pressures at the inlet and outlet of the turbine, the temperature and the flow rate are recorded with sensors. The recorded measured values are displayed digitally and processed further in a PC. The PC is used to calculate the power output data of the examined turbine and to represent them in characteristic curves.
