【Product Introduction】

The titanium-shielded wear-resistant ceramic fan volute is a core fan component designed for harsh industrial environments. It works in coordination with the wear-resistant ceramic impeller to form a complete, high-efficiency wear-resistant fan system. The volute adopts ceramic composite materials and an innovative structural design, enabling stable operation under extreme conditions such as high dust, strong corrosion, and high temperatures, significantly extending the overall service life and efficiency of the fan. It is suitable for material conveying, flue gas treatment, and ventilation systems in the power, metallurgy, cement, and chemical industries.

【Core Advantages】

1. Ultimate wear resistance and erosion resistance

Multi-layer composite ceramic liners: The inner wall of the volute is covered with high-density alumina (Al₂O₃) or silicon carbide (SiC) ceramic liners, with a surface hardness of HRA88-92 and wear resistance 6-10 times that of ordinary steel volutes, effectively withstanding continuous impact and wear from high-speed dust-laden airflow.

Gradient structural design: The ceramic layer and the high-strength alloy steel body are bonded through a ceramic-metal composite manufacturing process, avoiding the problem of traditional adhesive-mounted liners being prone to detachment and ensuring long-term stability.

2. Corrosion resistance and high-temperature performance

Ceramic materials offer strong resistance to acid and alkali corrosion, enabling long-term use in corrosive gas environments with a pH of 3-11, with a temperature resistance of up to 750°C or higher, making them suitable for high-temperature flue gas treatment and chemical exhaust emission scenarios.

3. Efficient airflow guidance with reduced energy consumption

Fluid-optimized volute structure: The volute flow channel curve is optimized based on CFD simulation technology to reduce airflow turbulence and localized vortices. When paired with the ceramic impeller, it can improve fan efficiency by 8%-12% and reduce operating energy consumption.

Enhanced sealing: The volute interface adopts an embedded ceramic sealing ring design to reduce air leakage and improve the overall air tightness of the system.

4. Modular maintenance with controllable costs

The volute adopts a split structural design, allowing severely worn local areas to be individually replaced with new ceramic liners, avoiding complete scrapping and reducing maintenance costs by more than 40%.

【Application Scenarios】
