China Rubber Rings Manufacturer introduces the common classification of rubber seals:
1. Rubber gasket, a sheet-shaped rubber product that acts as a seal between two static surfaces of a metal flange or other connecting parts is collectively called a rubber gasket. It can be made by molding method, or can be punched with vulcanized film. It can be widely used in all kinds of mechanical equipment, playing the role of gasket, sealing, cushioning and so on.
2. V-shaped rubber seal, a kind of rubber seal for reciprocating motion. The cross-section is V-shaped, and it is rarely used alone. It is generally used in combination with a pressure ring with a cloth fabric, a support ring and several V-shaped sealing rings. The number of sealing rings depends on the sealing pressure. The V-shaped sealing ring is molded by rubber cloth or pure rubber. The rubber material is generally NBR. The pressure ring and the support ring are generally pressed by harder rubber cloth. The support ring can also be pressed by hard plastic. V-shaped seal assemblies are mainly used for piston rods and plugs of heavy equipment. This seal assembly can provide good stability and good wear resistance, and can prevent the seal ring from being squeezed into the gap, even under severe conditions, such as axial or radial vibration, sudden pressure, and temperature changes And so on can still provide better sealing effect. It is suitable for hydraulic oil, water, emulsion and other media. The working pressure can reach more than 40 MPa, the surface linear velocity is generally 0.5m?s-1, and the working temperature is -30～120 ℃.
3. Drum rubber seal, a kind of compound reciprocating seal. The section is drum-shaped, also known as piston sealing ring, which is designed for one-way and two-way action pistons. There are different cross-sectional structures according to the requirements of use, but they are all composite elastic sealing rings made by direct molding of NBR and rubber cloth. When using the tape, two plastic retaining rings or L-shaped bushings must be attached. The interference of the sealing lip and the compression of the cross-section make the lip tightly pressed against the sealed surface to ensure the initial sealing. This type of seal is particularly suitable for large hydraulic lifting plugs, stable hydraulic cylinders, etc., and its allowable working pressure is as high as 75MPa, and the linear velocity is 0.5m.
