The problem with the electric fan?

Lubrication characteristics and requirements of electric fans (ventilators)

Electric fan bearings run at high temperature, so wear-resistant lubricating oil with good viscosity and temperature should be used. L-FD5 ~ 10 bearing oil or HL hydraulic oil is better, and it is usually oiled once a year before or after use. Swing gear and timing device should be lubricated with No.2 lithium-based or calcium-sodium-based grease, and the grease should have good adhesion. Lithium-based grease is lubricated once every 2-3 years, and calcium-sodium grease is lubricated once a year. When lubricating, remove the old grease first, and then apply new grease. And must pay attention to, before operation, must clean up the dust near the oil hole or oil hole cover, don't fall into the lubrication parts.

The electric fan motor is generally 30-60W, and the speed can be adjusted by 600- 1500r/min, and it is generally divided into 3-4 gears. It is required to be used for at least one year or three years without re-lubrication. Therefore, electric fan manufacturers often seal the corresponding grease, such as 1 or No.2 compound calcium-based or lithium-based oil. Save users the trouble of refueling themselves, and use it for a certain period of time before changing the oil. Some products are lubricated with lubricating oil (HL hydraulic oil or other engine oil) and refueled once a year, while some products use self-lubricating bearings or oil-bearing without oiling.

Electric fans are used seasonally and should be covered with dust cover when stored in idle season.
