REGENERATIVE TYPE FLUID MACHINERY HAVING GUIDE VANE ON CHANNEL WALL

摘要

PURPOSE: A regenerative type fluid machinery having a guide vane on a channel wall is provided to reduce energy waste due to turbulence in an impeller groove. CONSTITUTION: A regenerative type fluid machinery having a guide vane on a channel wall comprises an impeller(10), a casing(20) and a flowing channel(30). A plurality of vanes(12) is formed on the impeller. A plurality of vans is formed along the outer circumference as a radial shape. The impeller is disc type. The impeller is built in the casing. An inlet(32) and an outlet(34) are respectively located on the both ends of the flowing channel. The flowing channel is formed in the inner side of casing in the columnar direction.
