STAGE OF STATOR OF A CENTRIFUGAL MULTI-STAGE PUMP

摘要

A stage of a stator of centrifugal multi-stage pump includes a disc, body of section of stator and threaded means for connection of component parts of the stage of the pump. Additionally it includes another disc that is connected to the first one in zone of the lug at the side surface of the second disc, this has width that corresponds to thickness of continuous flow channel of the working wheel and in the lug channels of the guide apparatus are formed, and third disc that is as well connected to the first disc in the zone of the lug at the side surface of the third disc, at the side opposite to the side of connection of the second disc. In the lug on the side surface of the third disc continuous flow channels are formed as well, and the body of the section of stator is arranged as a ring that is attached to the ledges of the second and third discs.
