【 摘 要 】

The optimization of fan performance under changed conditions has important significance for the practical application of the fan. In view of the low efficiency of the original fan, the stable working flow span of the flow pressure curve is narrow, and it is difficult to meet the performance requirement after the working point change. Without changing the radial and axial dimensions of the fan, the performance of the original fan is optimized so that it increases from the total pressure 16153pa to 17271pa when operating flow 1900m3/h, meets the optimized target of total pressure 17000pa, the performance increases by 6.9%, and makes the stable working range of its pressure curve widen.
