PUMPING CAPACITY OF PITCHED BLADE MULTI-STAGE IMPELLERS

Popis výsledku v původním jazyce

This paper extends knowledge about flow in agitated batch with the pitched blade multi-stage impellers. Effects of various geometrical parameters (blades number, distance between impellers) of the pitched blade multi-stage impellers on the pumping ability have been investigated. Axial velocity profiles were measured by LDA (Laser Doppler Anemometry). Axial pumping capacities were obtained by integration of measured axial velocity profiles in outflow from impellers. Main attention was focused on the effect of the distance between impellers in multi-stage configurations, on their pumping capacity and flow in the mixing bath in comparison with independently operating pitched blade impeller with same geometry. In case of relatively close distance between impellers H3/d = 0.5 - 0.75, the multi-stage impeller creates only one circulation loop and the impellers itself behave identically as pumps in series. However for relative higher distance of impellers than H3/d = 1.25, the multi-stage imp
