Abstract
PURPOSE: To make a centrifugal blower in small size and with high efficiency by application of the diffusion theory, with which the flow from the outlet of impeller of a multivane blower to the spiral casing is considered as a divergent flow, and by using an equation to determine the configuration of this part.
CONSTITUTION: The outlet angle β of an impeller 3 of multivane blower shall be chosen between 160°W180°. The configuration from the outlet of impeller 2 to the spiral casing 1 is designed so that the characteristic parameter X, which can be expressed as above the illustration, will be in an extent of -0.6W-0.4, where A: Outlet area of impeller 2, B: Sectional area of throat 6 of spiral casing, α: Angle at outlet of impeller 2 formed from absolute flow speed to circumferential direction, λ: Mean diffusive angle of spiral casing 1 with respect to circumferential direction, R2 Radius of outlet of impeller 2, and L: Distance from tongue tip 9 of spiral casing to discharge hole 7. According to this design, the divergent flow from the outlet of impeller 2 to the spiral casing 1 will have the optimum condition and the efficiency of the blower can be greatly enhanced.
