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.
What are the precautions for the maintenance and maintenance of large ceiling fans?
Manually check whether the indicator light, voltage and ammeter are working normally, whether there is abnormal sound in the operation of each part of the industrial fan, and whether the three current values are balanced.

What are the precautions for the maintenance and maintenance of large ceiling fans?
One. Repair and maintenance of circuits:
1. Check whether the mechanical switching action of the regulating valve is reliable and flexible, and whether the switch angle mark is clear.
2. Manually check whether the indicator light, voltage and ammeter are working normally, whether there is abnormal sound in the operation of each part of the industrial fan, and whether the three current values are balanced.
3. Check whether the components in each remote control box are normal.
4. Start and stop three times in a row, please check whether the remote control at each point is correct and reliable.
5. Test run for two hours, observe whether the motor bearing temperature and motor temperature rise are normal. The fan is operating normally. For industrial fans, regular maintenance should be carried out every six months and the situation should be recorded to allow the normal operation of industrial fans.
Two. Maintenance and servicing of motor fan blades
1. Disconnect the main power supply and check whether the motor grounding wire is good.
2. Tighten the screws and couplings of each part.
3. Check whether the insulation resistance of the motor meets the requirements, and check the main circuit contacts. If the contacts are severely ablated, the contacts should be replaced.
4. Since the fan blades are exposed to the outside for a long time during use, they are easily contaminated by dust, so they need to be properly maintained.
