2 FLUID MACHINES HYDRAULICS Educational and Training Equipment Water has been used since the beginning of mankind to help man in his activity. During the centuries have been developed a number of machines to make a better use of water. Pumps, turbines find a large use in many fields: agriculture, electricity, production industry, mechanical industry, energy conversion, etc. The equipment designed and manufactured by PRODIT Company give to the schools the tools to investigate and understand the behaviour, the characteristics, and the performances of the hydraulic machines. In the production of these equipment has been given a great care to their didactic validity and to the corrosion prevention to guarantee a long lasting. For these reasons, where possible, the pumps head have been replaced with others realized in transparent material to make it possible to follow the fluid path throughout the blades and to understand the cavitation phenomena. The use of electronic instruments for temperature, torque, and revolution speed readings, made these equipment self-sufficient to carry on all the experiments.
