Axial fan basic principle debugging operation

Release Time：2021-07-20

Axial fan blades operate in a manner similar to the wing of an airplane, except that the latter acts lift upward on the wing and supports the component of the airplane, whereas axial fans fix the orientation and move the air.
The cross section of an axial flow fan is generally an airfoil section. The blades can be fixed in position and can also rotate around their longitudinal axis. The distance between the blade and the air flow viewpoint or the blade can be unadjustable or adjustable. Changing the blade viewpoint or distance is one of the first advantages of an axial flow fan. The small blade has a lower flow rate from the viewpoint, while the added distance can make the axial flow fan have a higher flow rate.
Advanced axial flow fans can change the blade distance during fan operation (which is similar to helicopter rotors), and then change the flow accordingly. This is called variable blade (VP) axial flow fan.
Axial flow fan, also known as partial fan, is a kind of fan commonly used in industrial and mining enterprises. It is different from ordinary fans. The motor and blades of axial flow fan are all in a cylinder, and the shape is a cylinder. It is used for partial ventilation, convenient equipment and ventilation.
When the axial flow fan moves to the left, the positioning shaft of the axial flow fan also moves to the left together, taking A in the gear sleeve as the fulcrum, so that the rack of the servo valve moves to the right until the servo valve blocks the oil holes of oil passages ① and ② and stops, and the moving blade operates stably under the new equipment angle.
The layout of the axial flow fan is compact and elegant. The box body of the fan adopts the frame and the box plate assembly plan. The frame is formed by one-time stretching of the metal cold bending forming unit of the ancestors in the sea. The box plate is a compound plate layout, and the inner layer is silencing data, further reducing noise.

1. The foundation of the axial flow fan device must exceed the roof, and the outside must be flat to prevent water leakage. The axial flow fan must be embedded with anchor bolts.
2. Add a layer of 5mm rubber plate between the fan base and the foundation to reduce vibration. The anchor bolts should be equipped with spring washers to avoid loosening the duration.
3. Before debugging and operation, all parts of the fan should be specifically reflected, and the migration and transformation impeller should be free of stagnation, sticking and rubbing signs.
4. At the beginning of the trial operation, first jog the electromechanical to reflect on whether the impeller torsion deviation is accurate (looking down, the impeller should rotate counterclockwise).
5. There should be no abnormality during trial operation or abnormal utilization. Voltage, current, vibration, and noise should be within the abnormal scale.
