How to replace the bolts of the ceiling fan
Rust on ceiling fan bolts is a common phenomenon, especially on iron bolts. Generally, bolts that have been in operation for more than 5-8 years will have varying degrees of rust, especially in harsh operating environments, which will accelerate and exacerbate the phenomenon of bolt corrosion. In order to improve the safety and operational performance of electric fans, it is necessary to repair and replace corroded bolts for long-term use. However, individual bolts that are severely rusted or even "rusted to death" can be difficult to loosen. Here are several common methods for loosening corroded bolts.
What are the advantages of the three-leaf ceiling fan use process
In many factories, it is often seen that three-leaf ceiling fans will be installed to increase indoor air circulation and reduce room temperature, the common structure and strong skills of industrial electric fans
Method for Judging the Quality of Ceiling Fans
In specific occasions such as large-scale production enterprises and labor-intensive enterprises and animal husbandry, etc. often need to use heat-resistant and wear-resistant moisture-proof industrial fans, different moisture-proof industrial fans have great differences in effectiveness and energy consumption, so the following article on the measurement of moisture-proof industrial fans three key content to make a brief description.
Do large ceiling fans need to be lubricated?
Large ceiling fan is a low-energy ventilation cooling equipment, favored by many customers, but because the ceiling fan is suspended in the air, maintenance is more troublesome, so many customers are worried about whether the large ceiling fan will rotate after a long time of use, do you need to replace the lubricating oil once a few months like maintaining the car? Let's answer this question for you.

Large ceiling fan is a low-energy ventilation cooling equipment, favored by many customers, but because the ceiling fan is suspended in the air, maintenance is more troublesome, so many customers are worried about whether the large ceiling fan will rotate after a long time of use, do you need to replace the lubricating oil once a few months like maintaining the car? Let's answer this question for you.
We know that the large ceiling fans on the market are mainly divided into two motor types.
One is the traditional gear reduction motor, its working principle is to use electric energy to drive the size drive motor, the gearbox needs lubricating oil for lubrication and heat conduction, which is the traditional motor gearbox needs to leave an exhaust hole for the gas discharged from the gearbox rotation. As with all lubricating power units,
Such a gear reduction motor large ceiling fan needs to be regularly replaced with lubricating oil, in half of the normal use environment, can be 2-3 years to carry out a lubricating oil more slippery, in the environment is more harsh, need to be replaced once in 1-2 years. To replace the lubricating oil, it is necessary to use the recommended lubricating oil model according to the regulations on the gear machine.
The second is the more popular brushless direct drive motor in recent years, this motor is using the principle of electromagnetic induction, the motor is a magnetic ji and coil, there is no lubricating oil, so this brushless direct drive fan does not need to replace the lubricating oil.
When customers use large ceiling fans, they should distinguish what kind of motor fan, if it is a gear reduction motor, they need to replace the lubricating oil regularly according to the maintenance instructions of the motor and the use environment.
