STRUCTURE FOR FILTERING ABRASIVE PARTICLES OF TURBO COMPRESSOR

摘要

PURPOSE: An abrasive particle filtering structure of a turbo compressor is provided to extend the lift of constituent parts by preventing abrasive particles from flowing into the gap between the mutually moving parts. CONSTITUTION: In a turbo compressor including a rotary shaft(40) coupled to a motor(30) for being rotated, impellers coupled to both end parts of the rotary shaft, a journal bearing(50) supporting the rotary shaft in radius direction, and a thrust bearing(70) supporting the rotary shaft in axial direction, an abrasive particle filtering structure of the turbo compressor includes a magnet(80) mounted at the side of the journal bearing or the thrust bearing to attach abrasive particles.
