Abstract
1371540 Circumferential-flow compressors U ROHS 12 Dec 1972 [18 Dec 1971] 57279/72 Heading F1C A side-channel compressor comprises radial impeller blades 7 bent forwardly in the direction of impeller rotation with the angle of attack α 2 at the outer end of each blade being smaller than the angle of attack α 1 at the inner end. For compressors with a flow velocity of about 200 metre/ second and a peripheral speed of 70 metre/second, α 2 may be 0‹-30‹ and α 1 may be 50‹-70‹. With a flow velocity of 100 metre/second and a peripheral velocity of about 40 metre/second, α 2 may be 15‹-45‹ and α 1 may be 45‹-60‹. The land 10 between the inlet 8 and the outlet 9 has a recess 12 which is enlarged in the direction 14 of rotation and extends over at least one interblade chamber 13, preferably the largest of the chambers, which, as shown, are of unequal size because the blades 7 are unequally spaced to reduce noise. The blades are grouped in three unequally sized sectors over each half of the impeller circumference, the angular spacing between the blades in each sector decreasing from 9‹ to 6‹ in the direction of rotation. The axis of the inlet 8 is at an angle e which is generally, but no greater than, 45‹ to the plane of rotation.
