Abstract

The paper is aimed at investigating the operation of the pump with combined centrifugal-vortex stage. The constructed power characteristics show that the pump has rather a high pressure (H=12 m) and low power consumption (N=0.27 kW) with low fluid supply (Q=27 m3/day).

To determine the combined stage usefulness, comparative power characteristics of the pump with combined centrifugal-vortex stage with centrifugal and vortex pumps, having similar geometric dimensions are obtained. The comparative analysis shows that the pressure of the pump with combined centrifugal-vortex stage is 2.5 times higher than that of two pumps.

This data allows a greater understanding of the further study of pump operation with combined centrifugal-vortex stage.

The results of the tests allow concluding that the application range of pumps with combined centrifugal-vortex stage is quite limited: the oil industry, pressure boosting systems, fire suppression systems, as well as washing and sprinkler systems.
