The two-speed fan with two-speed motor stator winding is △ / YY (or Y / YY) connection Hebei axial fan, speed connections by changing the basic principles of axial fan motor stator windings to change the number of poles in order to achieve the purpose of speed, low speed when △ (or Y) way Shanxi axial fan prices, high-speed operation mode when YY. The electrical control box with wind breakers, protective devices and other electrical components must be correct and reasonable by matching fan rated capacity. Application of Principle: Application meridional acceleration method and "quasi-Three" flow theory Francis fan design uses conical wheel structure, twist the wing blade, inlet manifold plus home or curved silencer. Advantages: high pressure, air volume, high efficiency and compact structure, low noise, small size, easy installation. Uses: Widely used in hotels, restaurants, shopping malls, office buildings, stadiums and other senior civil through the exhaust pipe pressurized air supply and ventilation industrial and mining sites.
