The dust ring is mainly used on some hydraulically activated piston rods. Its function is to remove the dust outside the piston cylinder, avoid some particles, liquids and other contaminants from entering the sealed cylinder, and improve the sealing performance .
The role of the dust ring:
Dust seals are very important for the protection of some hydraulic equipment. If some dust enters the hydraulic equipment, not only the seals will be worn, but also some guide sleeves and piston rods will be worn more seriously. In addition, if these impurities enter the hydraulic medium, it will also have a certain impact on the operation of the valve and the function of the pump. If the situation is worse, many of these equipment may be damaged. After using the dust ring, the dust and debris on the piston rod can be effectively removed, but it will not cause any damage to the oil film on it, which is conducive to the lubrication of the seal.
