Abstract
PURPOSE: To make it possible to operate a compressor with a high efficiency ever a wide range of flow rate by attaching a multi blade rib consisting of a plurality of ribs to the side plate of an impeller inside a difuser and by streightening the flow of fluid discharged from the impeller.
CONSTITUTION: Multi blade ribs numbering from several pieces to over ten pices are installed to the side plate 1a of the impeller inside a defuser 4. One multi rib consists of three ribs 5a to 5c. The angle of the rib 5a on the most inward side diameter is designed to conform to the flow angle of fluid discharge from the impeller 1 at the design point. The shape of the multi blade rib 5 consisting of the three ribs 5a to 5c is so formed that it may conform to almost a logarithm spiral shape. Each rib 5a to 5c has a height of about 30% of a flow channel width of the defuser 4. This construction makes it possible to straighten a turbulent flow of fluid discharged from the impeller 1.
