Problems solved by technology

[0003] Existing axial flow fan impellers are generally one-piece, one is integrally welded, and the other is integrally cast. Since the blades and the hub are fixedly connected in these two molding methods, it means that when a certain blade breaks When it is damaged, the entire impeller will be scrapped, which increases the production cost of the user; at the same time, the integrated fan impeller is also extremely inconvenient during transportation and storage, which not only wastes more storage space, but also easily causes the blade to be damaged under heavy load. Deformation or breakage under pressure

Abstract

The invention discloses a modular split assembled axial flow fan impeller and an assembling method thereof. The impeller comprises a mounting shaft sleeve, a hub, wheel discs and blades, wherein the hub is arranged in the middle of the mounting shaft sleeve in a sleeving mode, the wheel discs comprise a first wheel disc and a second wheel disc, the first wheel disc and the second wheel disc are respectively clamped at two sides of the mounting shaft sleeve and are connected to the hub, and the blades are clamped between the first wheel disc and the second wheel disc and are fixedly connected to the first wheel disc and the second wheel disc; and during assembly, firstly, the hub is clamped in the middle of the mounting shaft sleeve and fixed through bolts, the first wheel disc is clamped at one side of the mounting shaft sleeve and fixed to the hub through bolts, the blades are fixed to the first wheel disc, and then the second wheel disc is fixed to the hub and the blades; and the impeller is reasonable in structural design of the blades, high in assembling stability and reliability and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of fan equipment, in particular to a modular split-assembled axial-flow fan impeller and an assembly method thereof. Background technique [0002] Axial flow fans are widely used, such as electric fans and air conditioner fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high. The performance of the axial flow fan is closely related to the performance of the fan impeller. The fan impeller is generally composed of a group of blades, blade discs, hubs, spoke discs and other components, and its core components are blades and blade discs. [0003] Existing axial flow fan...
