STRUCTURE OF TURBINE COMPRESSOR USING IMPELLER

摘要

PURPOSE: A structure of turbine compressor using impeller is provided to reduce errors of manufacture of the compressor by adjusting load to axial direction given by the impeller coupled with both ends of a driving shaft without reducing an outer diameter of the impeller. CONSTITUTION: An impeller(30) equipped in a turbine compressor includes a hub(30a); blades(30b) and multiple pressure attenuating grooves(30c). The hub is coupled with a driving shaft to receive rotating power of a motor to rotate. The blades are placed on a front surface of the hub to receive rotating power of the hub to compress outside fluid. The pressure attenuating grooves are formed on an outer ring of the hub to reduce load of the impeller to axial direction.
