FIELD: equipment for investigation of working processes in hydraulic machines, particularly in installations visualizing the flow in their impellers. SUBSTANCE: model comprises casing 1 with transparent cover 2 and impeller 4 with blades 5, driving disc 6 and transparent cover disc 7. Container capsules 8 filled with dyestuff granules adjoin the driving disc 6. Capsules 8 communicate with interblade channels 10 through holes 11 in driving disc 6. Permeable walls of capsules 8 face the periphery of impeller 4 and have lips adjoining the driving disc 6. Lips and capsules 8 form channels for dyestuff liquid in the zone of permeable walls. In operation the new dyestuff granules are moved by centrifugal force into the zone of permeable walls. EFFECT: improved design. 3 dwg
