[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --SWF Francis fan] structural properties are mainly impeller fan, chassis, import collector, deflector, electric motors and other components. Impeller meridian acceleration characteristics of twisted flat welded on wheels. After balancing check, the fan speed test, with good aerodynamic performance. Circular enclosure with silencer function is coupled into a whole set of wind. Outlet provided with baffle, having good air distribution, pressure stability. Uses HL3-2A [SWF (B)] is widely used series Francis fan ventilation and fire temperature exhaust tunnels, underground garage, senior civil construction, metallurgy, factories and other places, HL3-2A [SWF (B)] Fans of the series conveying gas temperature must not exceed 80 ℃, special circumstances can be used riot Francis fan. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - centrifugal fan blower] work, power machine (mainly motor) drives the impeller rotates within the volute casing, impeller air through the suction port from the center inhalation. Due to the dynamic action of the gas roof fan, gas pressure and speed of the blade can be improved, and the centrifugal force along the road leaves Shuaixiang chassis exhaust fan fire, discharged from the exhaust port. Because the gas flow in the impeller is mainly in the radial plane, so called fan runoff. Centrifugal fan impeller and casing composed mainly by the pressure blower, small fan impeller is mounted directly on the motor, the large fan by coupling or connection with the motor pulley. Usually unilateral centrifugal fan inlet, with a single-stage impeller; flow can be bilateral intake, with two back to back impellers, also known as double-suction centrifugal fan. Suction fan, fan Tianjin, Tianjin Jinzhong Ji fan manufacturers are provided by Tianjin Jinzhong Ji HVAC purification equipment. Tianjin Jinzhong Ji HVAC purification equipment Limited (www.Jzjnt.com) strong, credible, in Tianjin fans, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the group into the brilliant and you work for a better future!
