Performance Overview and Structural Analysis of Multi-Blade Low-Noise Centrifugal Fans

Performance Overview and Structural Analysis of Multi-Blade Low-Noise Centrifugal FansIn recent years, multi-blade low-noise centrifugal fans have gained popularity among market users and industry peers. Indeed, this equipment is engineered to meet the demands of air conditioning, purification industries, environmental protection, and noise reduction requirements. By integrating principles of aerodynamic acoustics and aerodynamics, and building upon the assimilation of domestic and international technologies, this innovative product has been successfully redesigned and developed. Compared to conventional models, the primary advantages of multi-blade low-noise centrifugal fans include high airflow capacity, high total pressure, low noise levels, minimal vibration, and compliance with environmental protection and occupational safety standards. Users can select fan equipment in various sizes based on specific requirements. Standard sizes include 9-inch, 10-inch, 12-inch, 15-inch, 18-inch, 20-inch, 22-inch, 25-inch, 28-inch, and 30-inch. Each machine number features two distinct configurations: Type A and Type B. Construction Overview of Multi-Blade Low-Noise Centrifugal Fans: The blades of this unit are primarily crafted from high-quality galvanized steel sheets. Through an angled design, a more rational flow channel is formed in conjunction with an elongated front plate, ensuring high impeller efficiency. Bearings are spherical outer ball bearings with a roller table, allowing coaxial error adjustment on the outer spherical surface. Key components of the low-noise cabinet-type centrifugal fan include the main shaft and housing plates. The main shaft is fabricated from 45# steel to ensure sufficient smoothness and compact dimensions. Housing plates are assembled using stacked galvanized sheet metal. Additionally, to minimize operational noise, the multi-wing low-noise centrifugal fan incorporates sound-absorbing material within its double-layer panels, effectively dampening noise transmission. Generally, this multi-wing low-noise centrifugal fan is suitable not only for general ventilation but also for exhausting fumes and smoke.
