CENTRIFUGAL REPLACEMENT BLOWER ROTOR (OPTIONAL) Russian patent published in 2016 - IPC F04D29/22 F04D29/28 

FIELD: pump engineering.

SUBSTANCE: group of inventions relates to the field of pump engineering. Rotor of a centrifugal compressor comprises a plurality of working discs tightly interconnected without gaps by their ends. Each disk includes a plurality of flow passages of different lengths, one layer of uniformly distributed in one plane and the maximum possible filling area of the disc. Their channels are facing towards the center of the inlet disc and the outlet - to its periphery. Before the inlet of each flow channel its individual feeding cell is located. Cells are arranged across the surface of the end of disc spreading in concentric rows from the center to the periphery. Equal length flow passages of different disks are attached to each other and located in front of the inlets feeding cell precisely aligned to form in the rotor a plurality of suction cavities, each of which passes through the rotor on its one end to the other and has at one of the ends of the rotor an opening. At the opposite end of the cavity is closed. From each of the suction cavity only the flow channels are departing that feed the cells forming this suction cavity.

EFFECT: invention aimed at improving efficiency by maximizing the internal volume of the rotor and the possibility to take the working medium in one go from large areas.
