Product Description

Wear-resistant centrifugal fans are centrifugal fans with excellent wear resistance, mainly used for conveying gases containing dust, particles, and other abrasive substances. They are widely applied in industries such as cement, steel, chemicals, and power. The fan can be manufactured in either left-hand or right-hand rotation forms. From the viewpoint of the motor side, if the impeller rotates clockwise, it is called a right-hand fan, denoted by 'right'; if counterclockwise, it is called a left-hand fan, denoted by 'left'.

Features of wear-resistant centrifugal fans

1. Super-hard wear resistance: Some wear-resistant centrifugal fans have their working surfaces of the impeller coated with special alumina ceramics or toughened aluminum oxide ceramics, achieving a hardness of up to HRA95 or higher, with a low friction coefficient, effectively resisting wear.

2. Structural optimization: For example, using single-panel backward blades, reducing the blade outlet angle, and thickening the inlet leading edge to enhance the blade's impact abrasion resistance; reasonably adjusting the distribution position of wear-resistant linings and wear-resistant layers to improve the strength and wear resistance of the fan impeller.

3. Broad adaptability: Different wear-resistant materials and processes can be selected based on different operating conditions, such as dust content, particle size, and hardness, to meet the needs of conveying various abrasive gases.

4. Stable operation: After the impeller is formed, it undergoes static and dynamic balance correction and overspeed operation tests to ensure stable and reliable operation of the fan during operation, reducing vibrations and failures caused by impeller wear.

Wear-resistant technology measures

In areas prone to wear within the flow path, apply carbide, cobalt-based alloys, boron carbide, and aluminum carbide through overlay welding or spraying. On easily worn parts of the impeller and at weld joints between blades and front/rear discs, add wear-resistant linings. Alternatively, enhance blade wear resistance by affixing process wear-resistant ceramic tiles. Optimize flow path design in collaboration with Zhejiang University and General Ventilator Machinery Research Institute, utilizing 'secondary calculation method' and American ANSYS design software to reduce collisions between solid particles and blades, thereby extending blade life.

Common types of wear-resistant centrifugal fans

Ceramic wear-resistant fans, featuring ultra-hard wear resistance, corrosion resistance, and high-temperature tolerance, are widely used in power plant draft and exhaust fans. Coal powder centrifugal fans, such as the M9-26 model, are primarily used for forced ventilation in coal grinding systems of small and medium-sized thermal power plants, with wear-resistant materials or processes applied to components like the impeller and casing to improve fan durability. Dust removal fans, such as the C4-73 model, are mainly used in industrial dust removal systems suitable for high-dust environments in industries like metallurgy and building materials, with options for wear-resistant coatings or weld buildup on blades.

Zibo Hongcheng Fan Co., Ltd. specializes in producing over 50 series and more than 600 specifications and models of fans, which are extensively used in mining, coal mines, oil fields, chemical plants, kilns, metallurgy, boilers, textile, and building materials industries. Custom production and processing from provided drawings are available. Contact us for cooperation opportunities.
