Response of Blade Thickness to Hydraulic Performance of Stamping and Welding Multistage Centrifugal Pump
Based on CFD numerical simulation, the effect of blade thickness on hydraulic performance was studied in DQ100-64-22 stamping and welding centrifugal pump. Six types of impellers with different blade thickness were assembled in the same pump to be investigated under design condition. The result indicates that both of head and efficiency are getting lower with the increase of blade thickness. Particularly, the downward trend is more striking when the blade thickness surpasses 2mm, but pump head decreases more gently than efficiency as the blade thickness increasing within 2mm.
