CENTRIFUGAL COMPRESSOR HAVING A DIFFUSER WITH ROTATABLE VANES

摘要

PURPOSE: A centrifugal compressor having a diffuser capable of the rotation of a vane is provided to obtain optical efficiency as the fractional force of the vane is minimized by a ball bearing and rotated by being reacted sensitively to fluidic power. CONSTITUTION: A centrifugal compressor comprises an impeller(110), a diffuser, a ball bearing, a guide ring, and a vane(126). The vane is joined to a vane body so that fluid compressed by the impeller is moved. The ball bearing is arranged in one side of a vane fixing unit and joined by the vane and a joining member to be rotatable. The guide ring is arranged in one side of the ball bearing and joined to the vane fixing unit to be rotatable.
