Abstract
Contrarotating axial flow fan is a kind of the vital equipment in coal mines Their work conditions directly affect the safety of staff and production In the paper the performance of the contrarotating axial flow fan is experimentally investigated The study is focused on the fan performance the shaft power and the match between the motor and fan efficiency at different blade angles The results show that the blade angle 43°/26° has the best aerodynamic performance The first engine has a greater impact on the fan than the second one The blade angle with the best aerodynamic performance does not necessarily correspond to the one with the best match between the motor and fan efficiency The blade angle 43°/24° is the best choice for the operation of the fan in the present study
