High-pressure axial flow fan

Product Description

High-pressure axial flow fans can output very high air pressure while meeting airflow requirements. The fan consists of an impeller, motor, casing, guide vanes, and other components, resulting in a compact and highly efficient overall structure. The impeller operates smoothly after dynamic balancing; the casing is mostly made of welded steel plate or hot-dip galvanized steel plate, resulting in low vibration.

Technological Advantages

1. High Efficiency and Energy Saving Modern high-pressure axial flow fans are designed and manufactured using advanced technologies such as three-dimensional flow aerodynamic theory and variable sweep combined orthogonal blades. Total pressure efficiency can reach over 83%, with some larger models even exceeding 87%. By optimizing blade angles and aerodynamic models, the overall efficiency can be improved by 5% to 8% compared to the industry average.

2. Low Noise Operation High-pressure axial flow fans employ multiple technologies for noise reduction. They utilize biomimetic blade design, large chord length, inclined blade profile, low speed, and high pressure coefficient design methods. The main unit is equipped with an external double-layer silencer, resulting in ultra-quiet operation. Industrial-grade fans typically have noise levels below 85 dB(A), with some optimized models exceeding the national standard limit by more than 10 dB(A).

3. Compact and Robust Structure: The casing and structural components of the high-pressure axial flow fan are all welded from steel plates. The impeller undergoes dynamic balancing (balance quality grade G5.6), ensuring smooth operation. For applications requiring corrosion and explosion protection, explosion-proof motors and aluminum alloy impellers can be used to create explosion-proof fans.

4. Flexible Operation: High-pressure axial flow fans can be flexibly configured according to actual working conditions. Counter-rotating series fans can be used as a whole unit or operated in stages, allowing for single-stage or double/triple-stage operation based on ventilation requirements, resulting in significant energy savings. When using frequency conversion speed regulation, the fan speed can be adjusted within the range of 10–60 Hz, achieving wide adaptability to various operating conditions. The motor protection rating is typically IP55 or higher, with insulation class F or H, ensuring reliable operation under various conditions.
