Analysis on acceptance test of turbine model for Huangjinping Hydropower Station

In order to verify the hydraulic characteristics of the turbine model for Huangjinping Hydropower Station， the turbine model acceptance test is made. The test includes the instrument calibration， efficiency test， the output test， cavitation test， the pressure pulsation test， axial hydraulic thrust test， the volute pressure difference test， vane hydraulic torque test， runaway characteristics test， air entrainment test， dimensional inspection， etc. The acceptance result shows that the result of the initial test basically coincides with that of the acceptance test and all the hydraulic characteristics of the turbine meet the contract requirements concerned.
