Outside the design curve, the protrusions on the blades will cause turbulence during rotation, increase conflicts, reduce the ventilation efficiency of large industrial fans, weaken the function of the fans and increase operating noise. Smoothness is an important index to evaluate the unevenness of the fabric surface. The index is affected by non-structural factors and mainly depends on the shape formation and post-processing process of the manufacturer. In the manufacturing process of large industrial ceiling fans, the smoothness of the blade surface must be strictly controlled to ensure that the smoothness meets the design requirements of large industrial fans. Within the specified limit, the greater the kinetic energy of the gas at the same speed, the greater the curvature of the blade, that is, the greater the air volume and wind pressure. The greater the resistance of the blades, the greater the torque required by the engine.

The advantages of large industrial ceiling fans: easy to use, using a new stepless speed regulation system for frequency conversion. The friendly user interface allows you to enjoy the beauty of life brought by technology. It uses a very streamlined new streamlined propeller blade, allowing users to enjoy a three-dimensional airflow of 1 to 3 m/s, thereby creating a natural breeze. After rigorous selection and testing, the streamlined design has a good energy saving and consumption reduction effect, which can effectively cover an area of more than 1,500 square meters, and the higher power consumption is only 1.5kW. This is a good energy-saving product. Beautiful and durable products have undergone complex surface treatments. Industrial fans can avoid the pain of cleaning. At the same time, the product quality is strict, each set of products has been strictly tested, and the service life can exceed 10 years.


Large industrial ceiling fans usually use aluminum alloy to make fan blades. Because aluminum alloy has good toughness, it can withstand some physical deformation. When pushing air, aluminum alloy will also vibrate due to force, but the amplitude is usually small. Another common type of vibration is caused by uneven dispersion of fan blade mass and eccentricity between the center of gravity and the rotating shaft. If the fan blade area (mass) or eccentricity is large, large industrial fans or even the entire cooler may vibrate, which affects fan performance
