Corrosion centrifugal fan, motor (motor) driven impeller rotating within the volute casing, the air sucked through the intake port from the impeller center. Due to the dynamic action of the gas turbine sidewall, gas pressure and speed of the blade can be improved, and the centrifugal force along the road leaves the cabinet Shuaixiang discharged from the exhaust port. Corrosion centrifugal fan impeller and casing composed mainly of small fan impeller is mounted directly on the motor, the large centrifugal fan corrosion by coupling or connection with the motor pulley. Corrosion centrifugal fan usually unilateral intake Chongqing sidewall fans, with a single-stage impeller; flow can be bilateral air intake, with two back to back impellers, also known as double-suction centrifugal fan corrosion of the two-speed fan with dual speed motor stator winding is △ / YY (or Y / YY) in order to achieve the purpose of zaoqiang connection speed, connection speed by changing the way the basic principles of the stator windings wex-250d4 sidewall fans to change the number of poles fiberglass sidewall fan, low-speed work for △ (or Y) mode, high-speed operation mode for YY. The electrical control box with wind breakers, protective devices and other electrical components must be correct and reasonable by matching fan rated capacity.
