jiangmen ceiling fan Bolt corrosion is a common phenomenon, especially for iron bolts. Generally, bolts that have been in operation for more than 5-8 years will have varying degrees of corrosion, especially in harsh operating environments, which will accelerate the exacerbation of bolt corrosion. In order to improve the safety and operational performance of electric fans, it is necessary to inspect and replace corroded bolts for long-term use. However, individual bolts that are severely rusted or even "rusted" will be difficult to loosen. Here are several common methods for loosening corroded bolts.

1. Using a booster bar

Using steel pipes as force rods, a wrench is inserted inside to increase the force arm. During use, it is necessary to wrap the steel pipes with conflicting thick cloth to prevent slipping of the force rod due to the smooth wall of the steel pipe, which may cause damage to personnel and equipment.

2. Using an angle grinder

Use an angle grinder to polish and cut corroded bolts, but it is important to note that during high-altitude operations, maintenance personnel should pay attention to safety maintenance when using the angle grinder while standing on a ladder.

3. Using bolt crusher

There are specialized bolt crushers on the market that can easily crush bolts.

4. Using a saw bow

The use of a saw bow to break the bolts takes a particularly long time, and can only be used when the above three tools are not available on site and the power outage time is long enough.
