UPDATING OF POWER CONVERTER PLANT AND UPDATED POWER CONVERTER PLANT

摘要

FIELD: power engineering.SUBSTANCE: turbopump comprises the impeller running about the axle, preliminary distributor (204) with the stator blades to make the first water duct (C1) and the distributor (206') arranged between each pair of two adjacent blades. Said distributor comprises the guide blades arranged downstream of said stator blades in direction of water flow fed to said turbopump running in the turbine mode. Said guide blades make the second water duct (C2) between every pair of two adjacent guide blades. Claimed process comprises the steps including the reduction of the height of the first water ducts (C1) measured parallel with the impeller rotational axis and the reduction of the second water ducts (C2) measured parallel with the impeller rotational axis.EFFECT: reinforced structure.9 cl, 8 dwg
