In a significant advancement in fan manufacturing technology, the introduction of wear-resistant ceramic fan impellers is set to transform the performance and longevity of industrial fans. By adhering AL2O3 ceramic tiles to the outlet and the connection areas between the blades and the rear disc of the fan impeller, this innovative technology significantly enhances wear resistance. Building on traditional fan manufacturing techniques, the application of wear-resistant ceramic lining creates a superior wear-resistant surface on the main working areas of the fan. This results in a more than threefold increase in the service life of the fan impeller and a 10-30% improvement in fan efficiency.
Applications:
Wear-resistant ceramic fan impellers are ideal for a variety of demanding industrial environments, including:
- Power plant induced draft and exhaust fans
- Thermal power plants
- Coking plants
- Cement plants
- Steel plant blast furnace fans
- Sintering fans
- Circulation fans
- Other applications involving the transport of hard particles and corrosive media
Performance Features:
1. High Hardness and Extended Service Life:
The working surface of the fan impeller is equipped with ceramic tiles boasting a hardness of HRA80-88 (92%-95% ceramic). This makes the wear resistance to particle erosion more than five times that of conventional treatments like spraying, welding, and alloy powder block welding, and over 100 times that of 16Mn steel.
2. Safe, Reliable, and Efficient Operation:
Depending on the ceramic application process, the maximum temperature resistance can reach up to 450°C. The ceramic linings are highly resilient, suitable for high-temperature and high-vibration conditions. They can operate reliably for over seven years in environments ranging from 90-160°C. The incidence of unplanned fan shutdowns due to ceramic detachment is extremely rare, and wear issues are virtually eliminated. Additionally, the significant reduction in the weight of the fan impeller enhances operational efficiency, reduces maintenance time, and boosts economic benefits.
3. Simple and Convenient Maintenance:
The application process is straightforward, allowing for quick and efficient repairs in cases of abnormal ceramic detachment or localized wear. Importantly, the repair process does not introduce heat to the impeller, preventing deformation and ensuring the impeller and its components can be quickly returned to service.
4. Service Life:
The lifespan of a wear-resistant ceramic fan impeller depends on the size, concentration, speed, and impact angle of the dust particles. Generally, smaller particles, lower concentrations, reduced impact speeds, and smaller impact angles contribute to a longer service life for the fan impeller.
This breakthrough in fan technology not only promises enhanced durability and efficiency but also offers significant maintenance and operational cost savings, marking a new era in industrial fan performance.
