Description

Technical Field

[0002] Centrifugal fans are machines that rely on input mechanical energy to increase gas pressure and discharge gas; they are a type of driven fluid machinery. High-pressure axial flow fans are widely used gas conveying equipment in industrial fields. Their core function is to achieve axial flow of air or other gases and generate a high pressure difference in the process. Compared with ordinary axial flow fans, high-pressure models can overcome greater system resistance while maintaining a larger flow rate, making them suitable for applications with strict air pressure requirements. The processing of some high-pressure axial flow centrifugal fans requires moving a relatively large outer casing onto a processing table. During processing, the angle and position of the casing need to be adjusted multiple times, making the operation relatively labor-intensive. Utility Model Content
