Special wear-resistant ceramic fan impeller has stronger anti-corrosion ability and is more durable

The special wear-resistant ceramic fan impeller is a new product designed and manufactured by integrating modern new engineering materials and new three-dimensional flow theory. On the basis of traditional fan manufacturing technology, the special wear-resistant ceramic fan impeller adopts modern engineering ceramic materials. By using adhesive and inlay technology, a surface layer with excellent wear-resistant performance is formed on the working surface of the fan impeller, which can increase the wear-resistant service life of the fan impeller by more than ten times.

Collaborating with wind turbine manufacturing and design units, drawing on new design concepts and methods, and conducting overall optimization design and manufacturing can improve the efficiency of wind turbines by 10-30%. Ceramic performance and specifications: The main types of ceramics used include aluminum oxide, silicon nitride, silicon carbide, and their composite materials; Ceramic hardness: HRA86-92, special ceramic hardness can reach HRA94 or above; The average proportion is around 3; Wear resistance: more than 200 times that of carbon steel and more than 10 times that of high chromium cast iron; Main specifications: 10X10X1.5 10X10X3; 20X20X3. Ultra hard and wear-resistant: The ceramic hardness of the working surface layer of the fan impeller is HRA86 (toughened aluminum oxide composite material), which can reach HRA94 (silicon nitride, zirconia composite material) or above. Its erosion and wear resistance is at least 6 times that of high chromium cast iron, and at least 30 times that of 16Mn steel; The ceramic plate with a thickness of 1.5mm has been used for five years, and the average wear is less than 0.2mm. Adhesive (steel ceramic) with room temperature shear strength of 25MPa; It can reach 10MPa at 160 ℃.

1.5mm thick ceramic tiles, the adhesive provides a bonding force that is more than 100 times the maximum centripetal force on the tiles, and has good toughness, which can adapt to high temperature and vibration conditions. Under the operating conditions of 90-160 ℃, it has been in operation for more than three years and has adhered nearly 200 impellers of various types of fans, withstanding high temperatures, long periods of time, and batch tests. Wide applicability: The special wear-resistant ceramic fan impeller can be used in thermal power plant induced and exhaust fans, coking plants, cement plants, steel plants, blast furnace fans, and other working conditions with hard dust particles and corrosive media

1. On the basis of existing fan impellers, ceramic sheets can be added: any specification of ceramic can ensure that it can be pasted on all existing models of fan impellers;

2. Design and manufacture various models of new fan impellers according to the user's fan parameter requirements, and then paste ceramic sheets of different thicknesses and types.

3. When the operating temperature exceeds 180 ℃, our company's technology can be used, with a temperature resistance of up to 600 ℃, and the wear resistance life is not affected by temperature.
