Rust removal method for slewing bearing

2020-12-10

We know that the slewing bearing is an important part of many mechanical equipment and a kind of metal product. If it is not used for a long time, it may be easily rusted due to improper maintenance and protection, and then its performance will be reduced, or the entirety will be scrapped. Therefore, the rust removal of the slewing bearing is very important. The following is the rust removal method of slewing ring:

To keep the surface of the rotating support clean, it is necessary to choose a suitable solvent for cleaning according to the appearance of the anti-rust object, which will prevent the formation of serious corrosion. Surface cleaning can adopt chemical treatment cleaning methods and mechanical cleaning methods. When the surface is dry, do a good job in controlling the temperature and wait until most of the area is dry before wiping it with gauze. When altering the anti-rust oil, different methods should be adopted to alter the appearance of the bearing. Miniature bearings can be directly immersed in anti-rust grease. If you encounter a special shape, you can choose the painting method, so that it is not easy to accumulate. There are many factors that cause metal corrosion. The chemical composition of the metal itself will also cause corrosion, or the temperature and humidity of the environment where the item exists will also cause corrosion.

Soak the reversal support in the anti-rust tank: soak the reversal support in an aqueous solution of 5% sodium nitrite and 0.6% sodium carbonate. This method is very effective for the anti-rust effect of the reversal support. The disadvantage is : The method of immersing in the anti-rust tank requires many anti-rust tanks and other equipment to assist it, which will take up a lot of space, and the treatment and handling will be more inconvenient.
