| Abstract | ||
| In the present paper, the effect of change the blade configurations of the centrifugal pump impeller on its performance has been investigated. The pump under investigation has been designed and manufactured to be able to change its blades configurations in a way that the performance of the pump could be measured. The blades configurations have been tested for conventional blades, as well as split to two and three parts. The split blades were tested for clockwise and anti-clock-wise shifting. The experimental test rig has been carried out and the pump performances, (speed- head- flow rate- power and efficiency) have been measured for conventional impeller blades configuration, as well as for eight iterations of different impeller configurations according to the blades arrangement for different rotational speed ranged from 700 to 1450 rpm. The main blade configuration parameters are the splitting angle (forward or backward) and splitting diameter. The results showed that, for the same pump rotational speed, the pump head, efficiency and design flow rate, may increase or decrease by 12 to 16 %, compared to the basic impeller configuration. | ||
