Abstract
FIELD: jet-producing equipment. SUBSTANCE: pump unit has air ejector 1 with active supersonic nozzle 2 and fluid-circular pump 3 with working wheel 4 coupled to its outlet. Diameter of critical section of active supersonic nozzle 2 amounts to (0.018-0.035), where B and D are width and diameter of working wheel 4 correspondingly. Pump unit works as follows fluid-circular pump creates rarefaction and thanks to it atmospheric air is fed through active supersonic nozzle 2 into ejector 1 with supersonic velocity and ejects pumped away gas. Mixture of air and gas goes to fluid-circular pump 3 where pressure increases. Selection of ratio of dimensions of active supersonic nozzle 2 and working wheel 4 makes it possible to enhance productivity of pump unit. EFFECT: enhanced productivity of pump unit. 1 dwg
