Products Description
Duct axial flow fan
Material Characteristics
High Strength and Durability: Cast iron has high strength and hardness, enabling it to withstand the mechanical stress and airflow
impact during the operation of the fan. It is suitable for scenarios such as industrial ventilation that require long-term continuous operation. Good corrosion resistance: Cast iron has relatively good corrosion resistance in general atmospheric environments and ordinary industrial environments. It can resist erosion from certain levels of moisture, acids, alkalis, and other substances, making it suitable for ventilation and dust extraction under general working conditions.
Good shock absorption and noise reduction performance: The damping properties of cast iron enable it to effectively absorb and attenuate the vibration and noise generated during the operation of the fan, which helps reduce the operating noise of the fan and
provide a quieter working environment.
provide a quieter working environment.
product feature
Anti-corrosion treatment: Before installing a new machine, apply anti-rust paint (epoxy zinc-rich primer + topcoat) to the surface of cast iron components. Inspect once a year and touch up the paint promptly on damaged areas. Regular cleaning: Clean the dust and oil stains on the impeller and the inner wall of the casing every 1-3 months to avoid accumulation that may cause corrosion or
increase operating resistance. Lubrication maintenance: Regularly add lubricating oil to the bearing housing and check if the cast iron bearing housing has cracks or oil leakage. Temperature monitoring: Prevent the fan from operating under over-temperature conditions. If used in high-temperature scenarios, add a heat insulation layer outside the casing. Vibration detection: Regularly (every 6 months) detect the fan vibration value. If it exceeds 4.5mm/s, check if the cast iron impeller is unbalanced or the casing is deformed.
Core applicable scenarios
Industrial workshops: Ventilation and air exchange in mechanical processing, textile, electronics, and food processing workshops
(suitable for temperatures ranging from -10℃ to 250℃, with dust concentration ≤ 100mg/m³). Public buildings: Ventilation and smoke exhaust systems in underground parking lots, large shopping malls, and subway stations (need to be equipped with fire resistant coatings to meet fire safety requirements). Equipment supporting: Boiler induced draft, heat dissipation of refrigeration
equipment, exhaust of industrial ovens, etc., capable of withstanding continuous 24-hour operation conditions. Special scenarios: Underground mines (without strong corrosive environments), tunnel ventilation, and other places with high requirements for material strength and durability.
