The industrial fan depicted in the first picture is a fundamental piece of equipment in industrial ventilation systems. It operates by using traditional bearing mechanisms to make the impeller rotate, thus realizing the functions of gas transportation and ventilation. It is extensively applied in diverse industrial settings, such as factory workshops for ventilation and the discharge of industrial waste gas. However, the mechanical friction inherent in traditional bearings leads to relatively high energy consumption. Also, it needs regular maintenance, including lubrication of bearings and inspection of components, to ensure its continuous and stable operation.
