The wear rings in the hydraulic cylinder is also known as wear -resistant ring or guide ring, which mainly plays the following role:
1. Reduce friction and wear: The wear ring is usually made of wear -resistant materials, such as polytefluorolythery (PTFE), bronze or other polymer materials. They are installed between the piston and the cylinder of the hydraulic cylinder to reduce the direct friction between them, thereby extending the service life of the hydraulic cylinder.
2. Provide orientation functions: The wear ring is used as the orientation between the piston and the cylinder to ensure that the piston moves smoothly and accurately in the cylinder. This helps maintain the sealing and movement stability of the hydraulic cylinder.
3. Prevent leakage: Due to the tight coordination and wear resistance of the wear ring, it can also prevent pressure leakage inside the hydraulic cylinder to a certain extent.
Operations about the wear ring:
Installation: When installing the wear rings, the surface of the cylinder and piston needs to be ensured without impurities and sharp edges. The wear ring should be gently put in the predetermined location to avoid excessive force caused by deformation or damage.
Lubrication: To ensure a good operation of the wear rings, you can use recommended lubricants to lubricate the wear ring. This helps reduce friction and improve the life of the wear -resistant ring.
Check and replacement: regularly check the wear of the wear rings. If obvious wear or damage is found, it should be replaced in time. When replacing, it should be ensured that the same specifications and materials of the original abrasion ring should be used.
In short, the wear ring plays an important role in reducing friction, providing guidance and preventing leakage in the hydraulic cylinder. Correct installation, lubrication and regular inspections are the key to ensuring effective work of wear rings.
