Optimization Design of Centrifugal Fan Applied in Air Flow Dyeing Machine
Centrifugal fan is the key components of air flow dyeing machine system,which directly determines the dyeing quality and energy consumption level of the airflow dyeing system.In order to optimize the geometric structure and improve aerodynamic performance of centrifugal fans aim in air flow dyeing machine,taking the maximized total pressure PtF and total pressure efficiencyηtF of the fan as the optimization aim,a surrogate model based on artificial neural networks combined with genetic algorithm with elite strategy is used to optimize the design of the centrifugal fan impeller.The volute is optimized based on the aerodynamic matching conditions of the impeller and volute coupling.The experimental results indicate that:the optimized design of the centrifugal fan with a more compact structure,and its total pressure and the total pressure efficiency increase about 500Pa and 5％respectively.
