Hydraulic parameters of preotation controlled pumps
AbstractAt the prerotation control there is an adjustable blade row before the pump impeller for producing a peripheral component of the inlet flow velocity. The effect of prerotation is changing along the H ─ Q characteristic and the range of control depends on the geometric parameters of the pump and prerotation unit. This study is dealing with the role of geometric and hydraulic parameters on the performance characteristics. The results are based on experiments and on CFD calculations.
