There are fan impeller, housing, import collector, deflector, electric motors and other components. Impeller meridian acceleration characteristics of twisted flat welded on wheels. After balancing check, speed test, with good aerodynamic performance. Wu Cheng Fan circular enclosure manufacturers, and silencing function is coupled into a whole set of wind. Outlet provided with baffle, having good air distribution, pressure stability. Second, the use of fans HL3-2A [SWF (B)] Series Francis fans are widely used in high-temperature exhaust ventilation and fire wucheng tunnels, underground garage, senior civil construction, metallurgy, factories and other places of the biggest fan of production Manufacturers, HL3-2A [SWF (B)] series fan conveying gas temperature must not exceed 80 ℃, special circumstances can be used riot Francis fan. 1, compact structure, easy installation, reliable operation: The fan than Axial or centrifugal fan volume of small arms in the case of the city of the same amount of wind, air pressure, and can be directly connected to the duct, mounted horizontally or vertically mounted fan, easy operation features. 2, low noise: The fan casing is specially designed to greatly reduce the outflow of noise. Under the unit amount of wind, air pressure unit working conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, get a higher fan pressure. In the mining industry, and senior civil ventilation system can replace the low-pressure centrifugal fan or replace the high-pressure axial fan silencer without requiring a lot of action. 3, wide application: This series of new products at a single speed and two-speed two models, according to different occasions, to change the angle of the fan is installed, change the number of leaves and conversion speed reaches its requirements.
