Vacuum rubber seals are sealing elements specially used in vacuum systems to ensure the sealing performance and operating effects of the vacuum system. Usually made of rubber material, it has the following features and functions:
- Sealing function: The main function is to provide reliable sealing to prevent gas and liquid from leaking from the vacuum system. It contacts the sealing surface to form a sealing barrier to prevent the penetration of gas and the entry of external impurities.
- Elasticity and sealing: It has good elasticity and compression and can adapt to pressure changes and temperature changes in the vacuum system. It can closely fit the sealing surface and maintain a stable sealing effect.
- Chemical Resistance: A certain level of chemical resistance is required to resist attack by the chemicals present in the vacuum system. Usually acid and alkali resistant, solvent resistant, and oxidation resistant rubber materials are used, such as fluorine rubber (FKM) or silicone rubber (VMQ).
- Temperature resistance: Vacuum rubber seals need to be able to maintain their sealing performance at different temperatures. The specific temperature range depends on the characteristics of the selected rubber material, which can maintain its elasticity and sealing properties at low or high temperatures.
- Wear resistance: Vacuum rubber seals need to have a certain degree of wear resistance to cope with the friction and wear that may exist in the vacuum system. Proper selection of rubber materials and surface lubricants can extend the service life of seals.
Vacuum rubber seals are widely used in various vacuum systems, such as vacuum tubes, vacuum equipment, laboratory equipment, semiconductor manufacturing, etc. When selecting and using vacuum rubber seals, it is necessary to select appropriate materials and specifications according to specific application requirements, working environment and pressure requirements to ensure stable sealing performance and reliable system operation.
What is the difference between vacuum rubber seals and ordinary seals?
Vacuum rubber seals differ from ordinary seals in the following aspects:
- Material selection: Vacuum rubber seals usually use special rubber materials, such as fluoroelastomer (FKM) or silicone rubber (VMQ), to comply with the requirements of the vacuum system. These materials have good chemical resistance and high temperature resistance, and can adapt to pressure changes and temperature changes in vacuum environments. Ordinary seals may use other types of rubber, plastic or metal materials, selected according to the needs of specific application scenarios.
- Sealing performance: Vacuum rubber seals are designed and manufactured with attention to their sealing performance to prevent gas and liquid from leaking in the vacuum system. They usually have higher sealing levels and stricter sealing requirements to ensure the stable operation of the vacuum system. Ordinary seals may be used under normal atmospheric pressure and have relatively low requirements for sealing performance.
- Elasticity and compressibility: Vacuum rubber seals need to have good elasticity and compressibility to adapt to pressure changes and temperature changes in the vacuum system. They can closely fit the sealing surface and maintain a stable sealing effect in a vacuum environment. The elasticity and compressibility of common seals may vary depending on the application environment.
- Chemical resistance: Due to the specific chemicals that may be present in vacuum systems, vacuum rubber seals often need to have high chemical resistance to resist chemical attack. In contrast, the chemical resistance of common seals may vary depending on specific material selection.
- Application areas: Vacuum rubber seals are mainly used in vacuum systems, such as vacuum tubes, vacuum equipment, laboratory equipment and semiconductor manufacturing. Ordinary seals are widely used in various equipment and systems under normal atmospheric pressure.
A specific application of brushless stick
Rubber sealing strips are usually used on brushless rods to ensure their sealing performance and reliability. Rubber sealing strips can provide good elasticity and resilience, adapt to various complex-shaped surfaces, and can effectively prevent leakage and dust from entering. In addition, rubber sealing strips also have excellent wear resistance, temperature resistance, corrosion resistance and aging resistance, and can maintain good sealing performance and service life for a long time. Therefore, rubber sealing strips are a commonly used sealing material in mechanical equipment such as brushless rods.
Vacuum rubber seals are essential components in vacuum systems, providing reliable sealing and preventing gas and liquid leakage. These seals are usually made of rubber materials, which have good elasticity and sealing properties and can adapt to changes in pressure and temperature. They are chemically and temperature resistant, ensuring they maintain their sealing properties at varying temperatures. Wear resistance is also critical to deal with friction and wear in vacuum systems. These seals are widely used in various vacuum systems.
