Description

Technical Field

[0001] The utility model relates to the technical field of blower auxiliary equipment, in particular to an impeller welding device for a centrifugal blower. Background Art

[0002] For centrifugal blowers, the impeller, also known as the working wheel, is the most important component of the compressor. The impeller rotates at high speed with the main shaft and does work on the gas. Under the action of the impeller blades, the gas rotates at high speed with the impeller. Affected by the rotating centrifugal force and the expansion pressure flow in the impeller, the pressure, speed and temperature of the gas are increased when flowing out of the impeller. The impeller is mainly welded by a wheel disc, a wheel cover, long and short blades, and an inlet ring.

[0003] However, the impeller of the existing centrifugal blower needs to spot weld the blades on the wheel before formal welding, so as to fix the position of the blades and facilitate subsequent welding. This will not only increase the workload of workers and reduce work efficiency, but also increase the company's losses and costs. It will also cause the position of the blade welding to be inaccurate, ultimately affecting the production quality of the entire impeller. After searching, it was found that the technical solution provided by the utility model with application number CN201520964651.2 also has the above-mentioned problems. Utility Model Content
