MRE250815G01 Hydro Plant Power Training Equipment Renewable Training Equipment Vocational Training Equipment
I.Overview The tests and investigations described below is ableto be carried out with the training hydropower test bench: The turbine is the use of hydraulic turbines. Impact of water turbine is a new kind of impulse turbine; The turbine will be the water pressure can be transformed into kinetic energy completely determined by the dealer. In the process of transformation, water jet nozzle in accelerated projected impact turbine blade tangential directly. The impact of the water jet is passed to the impact of water turbine. This is a pelton turbine demo impact the function of the water turbine model. The impact of the experimental unit of water turbine, needle mouth as water source of power, a pelton turbine and a transparent shell band brake on the front panel. Transparent cover to observe the impact of the water turbine, in the process of operation, through the nozzle adjusting handle to change the nozzle cross section, so as to adjust the flow of the nozzle needle to adjust. Analysis of the relationship between injection pressure andturbine mechanical power. Determination of Pelton turbine efficiency as a function of water jump, injector opening and load applied to the turbine. Analysis of the influence of water flow on turbine performance: the water flow rate supplied to the turbine is adjusted and its performance is measured in relation to the mechanical power applied to the turbine shaft. Study the relationship between injector opening and generated mechanical power: measuring of the mechanical power developed by the turbine while varying the injector openings. Optimization of turbine performance: testing with different combinations of water head height and injector opening to find the configuration that maximizes turbine performance. Study the behavior of sensors: Analyze the response of flow rate, pressure, velocity, and torque sensors under different operating conditions II.Technical data (1) Input power: three-phase five-wire system AC400V, 50Hz (2) The capacity of the whole machine: <1.5KVA (3) Weight: <260kg (4) Working conditions: ambient temperature -10℃～+40℃ relative humidity ＜85% (25℃)
