Why is it necessary to repair high-pressure fan impeller shafts?
The high-pressure fan shaft is a critical component in industrial fan systems, often installed in positions such as air supply fans, dust extraction fans, drying fans, and gas recirculation fans. These shafts are widely used in various mechanical engineering industries, including thermal power plants, cement manufacturing, metallurgy & steelmaking, petrochemical & oil refining, paper production, and construction materials manufacturing.
Operating continuously at high speeds, under heavy loads, and in harsh environments causes the shaft surface to suffer from:
- Pitting, scratches, or chemical corrosion
- Thermal deformation
- Dimensional wear at bearing seats or gear mounting positions
Timely repair helps maintain operational efficiency, reduce costs compared to full replacement, and minimize downtime.
