The invention discloses an impeller assembly of a centrifugal fan. The impeller assembly of the centrifugal fan comprises a hub, a middle disc, blades and front discs, wherein the middle disc and thefront discs are annular discs coaxial with the hub; and the middle disc is fixedly connected to the hub, the front discs are arranged on the two sides of the middle disc in the axial direction, and aplurality of blades which are clamped and fixed through the middle disc and the front discs and are distributed in the circumferential direction of the hub axle center are arranged between the middledisc and the front discs. According to the impeller assembly of the centrifugal fan, the structure that the front discs, the blades, the middle disc, the blades, and the front discs are arranged in sequence is formed, the pneumatic performance and the mechanical performance are good, the service life is prolonged, the maintenance frequency by workers is reduced, it is guaranteed that the impellerassembly of the centrifugal fan operates efficiently, the overall safety performance of the fan is improved, and the use and maintenance cost of the fan equipment is reduced.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to an impeller assembly of a centrifugal fan. Background technique [0002] The centrifugal fan is mainly composed of a casing, an inlet collector, an impeller, a motor and other components. The high-speed rotating impeller is used to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes to the radial direction when passing through the impeller, and then enters the diffuser. In a diffuser, the gas changes direction and the cross-sectional area of the duct increases to decelerate the gas flow. This deceleration converts kinetic energy into pressure energy. The pressure increase mainly occurs in the impeller, followed by the diffusion process. In a multi-stage centrifugal fan, a reflux device is used to ...
