Pneumatic sealing is a technology that uses air or other gases to provide sealing. It is usually used in pneumatic systems to prevent the leakage of gas, liquid or other substances and ensure the efficient operation of the system. The main features of pneumatic sealing include: Air pressure drive: Through the action of gas pressure, pneumatic seals can effectively close the sealing surface and prevent leakage. Low friction loss: Due to the lubrication of gas, pneumatic seals usually have a lower friction coefficient, which reduces wear and extends the service life. Strong adaptability: Pneumatic seals can work in a large range of temperature and pressure changes and are suitable for various pneumatic equipment. Sealing effect: It can effectively isolate external air, dust, moisture and other factors to ensure the sealing of the system. Self-adjustment ability: Pneumatic seals usually have self-adjustment characteristics. Even when the sealing surface has a certain amount of wear, it can automatically adjust the sealing pressure to maintain a good sealing effect. Common types of pneumatic seals include O-rings, V-rings, diaphragm seals, etc. They have different structures and application scenarios according to different working environments and needs.
