Innovation and Practice of Energy-saving Technologies for Centrifugal Fans

Centrifugal fans, as high-energy-consuming equipment in the industrial field, their energy-saving transformation has become the focus of the industry. In recent years, through the optimization of impeller structure, variable frequency control technology and the application of new materials, the efficiency of fans has been significantly improved. For instance, high-speed centrifugal fans can increase the total pressure by 13.3% and the efficiency by 2.5% by adding the number of blades, while the application of magnetic levitation bearing technology can reduce the transmission loss by more than 30%. In addition, the intelligent frequency conversion system can dynamically adjust the rotational speed according to the actual working conditions. After the transformation of a certain chemical enterprise, it saved up to 2 million kilowatt-hours of electricity annually. In the future, the combination of composite material impellers and AI algorithms will further push the boundaries of energy conservation.
