Optimization Analysis of Type 9-19 Centrifugal Fan in Coal Mine Based on Actual Production Technology
In order to further explore the possible optimization path of centrifugal fan in coal mine,taking model 9-19 centrifugal fan as an example,aiming at the unfavorable mechanical environment of its impeller model,through modeling and finite element analysis,it is clear that the blade part needs to be optimized,and the optimization and reinforcement mode of the blade rear disk part is optimized.The results show that the stress distribution of the optimized impeller model is significantly improved,and there is basically no risk of resonance,which indicates that the optimization design has made some progress,and it will have potential application value in practical work.
