A hammer oil seal is a sealing device installed on the hydraulic or pneumatic cylinder of a breaker hammer. Its primary function is to prevent grease leakage and impurities from entering the cylinder. It also provides lubrication and sealing, ensuring the hammer's proper operation. Depending on the material, breaker hammer oil seals can be divided into various types, including rubber, polyurethane, and fluororubber.
What are the functions of a hammer oil seal?
1. Preventing grease leakage
Through its unique structure and material, a hammer oil seal effectively prevents hydraulic oil or lubricating oil from leaking out of the hydraulic or pneumatic cylinder, maintaining stable pressure in the breaker's internal hydraulic system and ensuring the hammer's proper operation.
2. Preventing impurities from entering
A hammer oil seal also prevents dust, moisture, and other impurities from entering the hydraulic or pneumatic cylinder, protecting the hydraulic system from contamination and extending the hammer's service life.
3. Lubrication
In addition to sealing, the oil seal also provides a certain degree of lubrication, reducing friction and wear between internal components of the hydraulic or pneumatic cylinder, thereby improving the hammer's operating efficiency.
