Everyone knows that Industrial Fans are widely used in tall spaces such as industrial plants, logistics warehouses, waiting rooms, exhibition halls, gymnasiums, supermarkets, etc. because of their power saving, large coverage, and no space occupation. A common industrial cooling machine for cooling. But also because of the huge fan blades and long-term operation, it will inevitably produce noise, so how loud is this noise?
1. Wind noise
When the
Traditional Ceiling Fans is working, because the Traditional
Ceiling Fans blades periodically bear the pulsating force of the uneven airflow at the outlet, noise is generated. On the other hand, due to the uneven distribution of pressure on the blade itself and the blade, the disturbance to the surrounding air and parts during rotation It also constitutes rotating noise. In addition, turbulent boundary surface, vortex and vortex separation are generated when the gas flows through the blade, which causes the pulsation of the pressure distribution on the blade to generate eddy current noise. The noise caused by these three reasons can be comprehensively called wind cutting noise. Generally, Traditional Ceiling Fans with large air volume and pressure have relatively large wind cutting noise. the
2. Vibration
Assuming that the physical center of mass of the rotor and the center of inertia of the rotating shaft are not on the same axis when the Traditional Ceiling Fans rotor rotates, it will cause the rotor to be unbalanced. The close distance between the physical center of mass of the rotor and the center of inertia of the rotating shaft is called the eccentricity. The eccentricity is caused by the imbalance of the rotor. When the rotor rotates, due to the centrifugal force, a force is generated on the rotating shaft bracket to form vibration, and the vibration is transmitted to the machine through the base path. parts. the
3. Abnormal sound
Wind noise sounds like pure wind, but abnormal noise is different. When a Traditional Ceiling Fans is running, if there are other sounds besides wind noise, it can be judged that the Industrial Fans has abnormal noise. The abnormal sound may be caused by foreign matter or deformation in the bearing, collision caused by improper assembly, or uneven winding of the motor winding, resulting in looseness, which may cause abnormal sound. the
The first two types are normal noises. If it is the third type, you should pay attention to it. Although it will not cause major problems, it is better to prevent it before it happens. After all, safety is important.
