1. Deceleration that limits blade tip linear speed
Generally speaking, the air noise of a blade is proportional to the 5th order of the blade tip speed. In the design of blades, it is necessary to know the relationship between blade length and speed. For mature blades, noise reduction can be achieved if necessary, but a certain amount of air volume will generally be lost.
2. Lubricate the bearings
Bearings are the most important running components of large
HVLS Fans. It will run out of lubricant after being used for a long time. Therefore, large HVLS Fans will produce a lot of noise when running at high speed. In this case, a few drops of lubricant can be applied to the bearings of the large HVLS Fans. If not, you can use sewing machine oil instead, but do not use cooking oil.
3. Fix the
Hvls Ceiling Fans blades
High-speed rotation will generate a certain force, which will loosen the blades, causing a large gap between the blades and the bearings due to friction, and vibration noise will be emitted during operation. If you encounter this kind of noise, you should first remove the blades of the large HVLS Fans, tighten the screws, and then install the blades to avoid gaps between the blades and the bearings. Makes a vibrating noise.
4. Polish the fan blades
If the focus of the HVLS Fans blades does not form an eccentricity on the axis, it will not only produce greater noise, but it is also the core component of the Hvls
Ceiling Fans. So remove the blades from the Hvls Ceiling Fans and hang a thin wire in the center. After it comes to a standstill, watch which direction it sinks, and then gently grind the sinking end on the wheel to make the Hvls Ceiling Fans in a horizontal position before installing it.
