Optimization Design of the Spinning Multistage Centrifugal

Abstract:

This paper analyses the structure of the original spinning multistage centrifugal fan. Because of low pressure and low efficiency, optimization design was carried out for the original fan. Based on the aerodynamic calculations theory, the structure and pneumatic of single stage was studied. The influence factors are Inlet-flow loss, equivalent divergent angle, pre-swirl, Resonant frequency etc. Pneumatic recalculation and experiment are carried out for the multistage fan. Results show that after modification pressure of the multistage fan has increased raises 15.3 %.
