Mine Main Fan Axial Flow Fan:
The aerodynamic design of the mine main fan axial flow fan of the main fan for mining uses the contemporary advanced impeller machinery ternary flow theory and CAD design technology, and the impeller blades and fan flow passages are carefully designed by experts from the Beijing Keneng Energy and Power Research and Development Center of the Chinese Academy of Sciences to optimize each Various parameters can be used to reduce losses, improve efficiency, and ensure that the fan operates in a wide high-efficiency area under the premise of satisfying air volume and air pressure. The maximum static pressure efficiency at the design operating point is over 85%.
The mine main fan axial flow fan is mainly composed of two main engines. The two main engines are composed of an inner and outer air duct, a motor base and a motor. The impeller is directly installed at the shaft extension end of each motor. structure. The two-stage impellers are both working wheels and guide vanes, which not only avoids the energy loss of the transmission device between the motor and the impeller, but also avoids the energy loss of the middle and rear guide vanes of ordinary axial fans; at the same time, the specially designed hollow machine The airfoil motor cooling external circulation air duct reduces the ventilation resistance, so that this series of fans can achieve higher static pressure efficiency and full pressure efficiency compared with other fans, and has obvious energy saving effect.
