O-ring is a common seal, and its cross-section is round, hence its name. It is made of elastic material, usually rubber or silicone, and has good elasticity and self-sealing properties. O-ring is suitable for many forms of sealing, including static and dynamic sealing.
In static sealing, O-rings are placed between two parallel planes, such as pipe joints or valve seats. When subjected to compressive loads, the O-rings deform and fit tightly against the sealing surface to form an effective seal. The elasticity and self-sealing properties of O-rings make them effective in static sealing.
In dynamic sealing, O-rings are usually installed on the surface of shafts or holes to prevent leakage of liquids or gases. During movement, O-rings are subjected to shear forces and will deform to a certain extent. But over time, the O-rings will gradually adapt to the surface of the shaft or hole to form an effective seal.
O-rings are suitable for a variety of industries and fields, including machinery, chemicals, oil and gas, etc. In these industries, O-rings are widely used in the sealing of various pipes, valves, hydraulic systems and other equipment.
In short, O-ring is a common seal, suitable for various forms of sealing. It has good elasticity and self-sealing properties, can effectively prevent the leakage of liquid and gas. It is widely used in various industries.
