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.

Preventive measures for oil leakage in polyurethane seals Polyurethane seals are widely used in various industrial and engineering applications, such as hydraulic systems, pneumatic systems, rotating shafts, etc. However, if used improperly or of poor quality, these seals may experience oil leakage, which not only affects the normal operation of the equipment, but may also lead to environmental pollution and safety hazards. Therefore, it is crucial to take effective preventive measures to prevent oil leakage from polyurethane seals. Select high-quality polyurethane seals Choose polyurethane seals from reputable and stable quality suppliers. Ensure that the material quality, manufacturing process, and dimensional accuracy of the sealing components comply with relevant standards. Avoid oil leakage caused by the use of low-quality seals. Proper installation of polyurethane seals During the installation process, avoid scratching the seal and ensure that it is installed in place and pre compressed. During the installation process, specialized sealing installation tools should be used to avoid damaging the sealing lip or body. At the same time, it is necessary to ensure that the seal fits tightly with the groove to prevent displacement during operation. Prevent polyurethane seals from being exposed to air for extended periods of time Long term exposure to air can gradually harden polyurethane seals, leading to a decrease in their elasticity and potentially causing oil leakage. Therefore, during equipment maintenance and repair, it is important to minimize the exposure time of polyurethane seals to the air. For unavoidable exposure, protective packaging should be applied to seals exposed to air. Prevent contamination of polyurethane seals Contaminants are another important factor causing oil leakage in polyurethane seals. Therefore, it is necessary to prevent pollutants such as dust, impurities, and moisture from entering the seal. During installation and use, it is important to maintain cleanliness and avoid contamination. Meanwhile, for special application environments such as high temperature, high pressure, corrosive media, etc., polyurethane seals with anti pollution performance should be selected. Regular inspection and maintenance of polyurethane seals Regular inspection and maintenance of polyurethane seals are key measures to prevent oil leakage. By conducting regular inspections, potential problems can be identified and repaired in a timely manner, preventing the problem from escalating and causing oil leakage. During the maintenance process, it is necessary to strictly follow the maintenance guidelines provided by the manufacturer to avoid seal damage caused by improper maintenance. Using auxiliary sealing devices For certain high-risk application scenarios, such as high-pressure, high-speed, or high-temperature environments, it may be considered to add auxiliary sealing devices outside the polyurethane seal. These auxiliary devices can provide additional protection and reduce the risk of oil leakage from polyurethane seals. However, it should be noted that the selection and use of auxiliary devices should follow relevant standards and specifications to ensure their effectiveness. In summary, preventing oil leakage from polyurethane seals requires comprehensive consideration from multiple aspects. The selection of high-quality polyurethane seals, proper installation, prevention of prolonged exposure to air, prevention of pollution, regular inspection and maintenance, and use of auxiliary sealing devices are all effective prevention methods. By implementing these measures, the risk of oil leakage from polyurethane seals can be greatly reduced, and the operational efficiency and safety of equipment can be improved.
