Pneumatic Seal is a sealing solution designed specifically for pneumatic systems. With the continuous development of pneumatic equipment, Pneumatic seal plays a key role in ensuring the stable and efficient operation of the system.

2. Structure and Principle

Structure

Pneumatic seals usually have a variety of structural forms, the most common of which are O-rings and lip seals. O-rings are a simple and effective sealing structure, and their circular cross-section can be tightly embedded in the sealing groove. Lip seals have one or more sealing lips, which can provide reliable sealing under different pressure and motion conditions.

Principle

When there is gas flowing in the pneumatic system, the Pneumatic seal fills the tiny gap between the sealing interfaces through its own elastic deformation. Under the action of air pressure, the seal fits tightly with the sealed surface, preventing gas from leaking from the high-pressure area to the low-pressure area, thereby ensuring the pressure stability of the pneumatic system.

3. Material properties

Rubber

Nitrile rubber (NBR) is a commonly used material for Pneumatic seals. It has good elasticity and wear resistance, and can adapt to the frequent impact and friction of gas in pneumatic systems. At the same time, NBR has good compatibility with common compressed air media and is not easily corroded.

Silicone rubber is also used in some special pneumatic applications. Silicone rubber has good high and low temperature resistance, can maintain elasticity in a wide temperature range, and is suitable for pneumatic equipment with large changes in ambient temperature.

Polyurethane

Pneumatic seals made of polyurethane material have high strength and wear resistance. It can withstand high air pressure and frequent piston movements, and is especially suitable for pneumatic actuators that require long-term stable operation.
