CENTRIFUGAL COMPRESSORS PDF

MAIN COMPONENTS:

WORKING PRINCIPLE

THE GAS ENTERS THE IMPELLER EYE OF A CENTRIFUGAL COMPRESSOR IN AN AXIAL

DIRECTION WITH ABSOLUTE V. THE GAS THEN

FLOWS RADIALLY THROUGH THE IMPELLER

PASSAGE DUE TO CENTRIFUGAL FORCE. THE

IMPELLER ROTATES AT A VERY HIGH SPEED

(20000 TO 30000 RPM). ENERGY IS IMPARTED TO

THE GAS BY THE ROTATING BLADES WHERE IT

IS CONVERTED INTO KINETIC ENERGY AS IT

MOVES FROM RADIUS r1 TO r2, ALONG WITH A

SMALL PRESSURE RISE DURING ITS RADIAL

FLOW IN THE IMPELLER.
