Influence of the Change of the Impeller Blade Angle on Centrifugal Pump Performance
This paper aims to study the influence of the change of the centrifugal pump impeller blade angle on the performance,Taking a centrifugal pump as the object,thenumerical simulation method is used to analyze the in-fluence of the centrifugal pump with the distribution of the blade angle under different working conditions on the performance,inflow field and surface pressure.The result shows that when the blade angle is linearly distributed from the inlet to the outlet,the overall performance of the centrifugal pump is better.When the maximum position of the blade placement angle moves from the blade inlet to the outlet,the head continues to increase.The angle of the front half of the blade is positively correlated with the functional force of the blade.Functional force of the second half of theblade plays a leading role in the performance of the blade.
