What is the sealing principle of fluorine rubber skeleton oil seal?

Fluorine rubber skeleton oil seal is a widely used component in mechanical seals, and its sealing principle is mainly based on the following steps:
Adhering surface: The fluorine rubber skeleton oil seal needs to first adhere to the surface that needs to be sealed. This bonding process requires ensuring that there is no gap between the seal and the sealing surface to prevent leakage.
Compression: The fluorine rubber skeleton oil seal needs to be compressed during installation, which allows it to tightly adhere to the sealing surface. The degree of compression needs to be moderate to ensure that the oil seal is neither too tight nor too loose.
Blocking: The fluorine rubber skeleton oil seal effectively blocks the leakage path through its internal fluorine rubber material, thereby avoiding the leakage of lubricating oil or other liquids.
Elastic recovery: The fluorine rubber skeleton oil seal has good elasticity, which can maintain its shape and size stability even in long-term use or under external pressure, ensuring continuous sealing effect.
Corrosion resistance: Fluorine rubber materials have excellent chemical corrosion resistance, so fluorine rubber skeleton oil seals can be widely used in the treatment process of various acids, alkalis, salts and other chemical substances.
Temperature adaptation: Fluorine rubber materials have a wide temperature adaptation range and can maintain good performance in the temperature range of -20 ℃ to+250 ℃. Therefore, fluorine rubber skeleton oil seals are also suitable for sealing needs under various temperature conditions.
Wear resistance: The fluorine rubber material of the fluorine rubber skeleton oil seal has good wear resistance, which can maintain its shape and size stability during long-term use, thereby extending its service life.
In summary, the sealing principle of fluorine rubber skeleton oil seal is achieved through multiple advantages such as adhesion, compression, blocking, elastic recovery, corrosion resistance, temperature adaptation, and wear resistance, to achieve sealing effects on various liquids and chemicals.
