Study on the Influence of Impeller Front Disc Profile on the Performance of Mining Centrifugal Ventilators
Centrifugal ventilators are widely used in coal mines,and the impeller front disc profile has an important impact on the performance of the equipment.Firstly,the impeller structure of centrifugal ventilator is outlined,the numerical model of centrifugal ventilator is established by using SolidWorks and ANSYS software,and four typical impeller front disc profiles are designed,and the full-pressure coefficients and efficiencies of the four structures are comprehensively compared and analysed,and it is considered that the front disc profile Ⅲ has the most advantages.Based on the test method to verify the performance of the front disc line Ⅰ and Ⅲ,it is found that the test results effectively verify the numerical simulation results,and the front disc line Ⅲ has the optimal performance,especially in the high-flow working conditions,the performance advantage is more obvious.
