Analysis of the Influence of the Blade Installation Angle of FBD-type Counter-Rotating Local Ventilation Fan in Coal Mine
In order to investigate the influence of the installation angle of ventilator blades on the performance of the fan,the FBD-type counter-rotating local ventilator in coal mine is taken as the research object,and its influence on the mechanical properties and vibration characteristics of the impeller,which is the key component of the fan,is analysed.The results show that increasing the blade mounting angle will lead to an increase in the impeller stress and strain,while the effect on the vibration characteristics is not significant.This study can provide some reference for the subsequent blade installation work.
