Optimization of centrifugal pumps
Conclusions The inclination of impeller vanes should be increased to a final value of 80–130° near the outlet on a length corresponding to 15–50% of the total vane length.To optimize the flow regimes it is expedient to install in the zone of the increased vane inclination 1–5 additional short vanes with a length amounting to 0.6–1.2 of the length of the swept-forward tips of the main vanes.Impellers with an increased inclination of the outlet tips of the vanes and with additional short vanes in this zone increase the pump head by 30–95% for the same dimensions of the impeller and its rotative speed, increase the efficiency by 5–15% at high deliveries and by 1–3% at rated deliveries, and also increase the delivery by 5–80%.
