When corrosion Axial fan, motor-driven impeller rotating within a cylindrical enclosure, the gas enters the collector Francis fan, Francis fan Shandong gain energy through the impeller, increasing the pressure and speed of Hefei Francis fan, and then discharged in the axial direction. Arrangement of the axial fan has a vertical, horizontal and inclined three, small, only about 100 mm impeller diameter Francis fan specifications, large up to 20 meters. Small low-pressure axial flow impeller corrosion fan, chassis and other components collector, usually mounted on the wall of a building; large high-pressure axial flow fan corrosion by collectors, impeller, flow line body, chassis, diffusion tube and transmission components. Blades are uniformly arranged on the hub, the number is generally 2 to 24. The more blades, the higher the air pressure; blade mounting angle is generally 10 ° ~ 45 °, the installation angle is larger, the larger the air volume and pressure. The working principle and the cooling tower cooling tower is a device that uses water and air in direct contact heat exchange, which is mainly composed of fans, motors, packing, sowing water systems, tower, water dish and other components, mainly by action under the fan The air temperature is relatively low in the water with the filler material by heat exchange so as to achieve the purpose of lowering the water temperature. Tower construction and design conditions stated in the manual there, but we are now using water ton units are more commonly used international units. We usually refer to the cooling tower is open cooling tower means: A. It is a water distribution system in the tower by the water droplets or water spray into a film, the water flowing down from the packing, the air in packing in the direction of flow from the bottom up or the level of use of water evaporation and heat transfer away cold and hot water, waste heat equipment. B. refers to cross-flow of hot water from the tower through the packing down, and the air flows horizontally through the packing, hot water and air flow direction of a cooling tower was almost 90 ° (some manufacturers called orthogonal type or Orthogonal cooling tower). C. countercurrent column refers to the hot water from passing through the packing down, and the air flow from the bottom up through the packing, hot water and air flow direction was approximately 180 ° of a cooling tower (some manufacturers called convection cooling Tower).
