Acceptance test of turbine model for Pubugou Hydropower Station

In order to verify the hydraulic characteristics of the turbine model for Pubugou Hydropower Station, the acceptable model test is made. The test involves the instrument and meter calibrating, the efficiency test, the output test, the cavitation test, the flow condition survey, the water pressure fluctuation test, the air admission test, the axial push test, the spiral case pressure difference test and the runaway behavior test. The conclusion of the acceptance test is that both the behaviors of the model turbine and the converted to the real turbine accord with the contract demands.
