Abstract
PURPOSE: To obtain noise absorbing effect at low cost by arranging the throat part on the vanes on both sides of a main plate, opposing each other and shifted by 1/2 of the mutual distance between vanes, and by doubling the fundamental frequency of the noise generated in a blower.
CONSTITUTION: On both sides of the main plate 31 of a vane wheel 3, vanes 32 and 33 are arranged symmetrically right and left,and further, side plates 34 and 35 are installed. On a casing 5, are arranged a scroll back plate 51 and the throat parts 52 and 53 which constitute a part of the scroll back plate and are arranged each other at the position shifted by 1/2 of the vane pitch. The throat parts 52 and 53 are positioned, shifted by 1/2 of each pitch of the vanes 32 and 33. Thus, the number of times the vanes 32 and 33 pass through the throat parts 52 and 53 becomes the double of that of the apparatus on which the throat part is at a position, and the fundamental frequency of the noise generated is doubled.
