1. O-rings, (also known as: O ring, O ring, o-ring) is a circle in the shape of a mechanical gaskets, it is a ring of elastomer, cross section is circular, generally will be fixed in a groove, the assembly process can be two or more than two components compression, thus produce the sealing interface.Because the price cheap, simple manufacturing, reliable function, simple and installation requirements, o-rings are the most common seal with mechanical design.You can bear the brunt of the dozens of PASCAL (kip).O-rings can be used in static applications, there is relative motion between the parts is also used for dynamic applications, such as the shaft of the rotary pump and hydraulic cylinder piston.
2. Working temperature: -55~+250°C
3. (1)NR: Good abrasion resistance, High elasticity, breaking strength and elongation, Easy ageing, the air is heated becomes sticky, easy expansion and dissolved in mineral oil or gasoline, and alkali resistant, but not resistant to strong acid.
(2) SBR: Low cost of oil resistance material, Good water resistance, hardness below 70 good elasticity,
(3) NBR: Good oil resistance, water resistance, solvent resistance and resistance to high pressure oil, Good compression slanting, anti-wear and elongation
(4) SI: Good elasticity and good compressibility, Has good resistance to neutral solvent, excellent heat resistance, Excellent cold resistance, For the erosion of ozone and oxide with excellent resistance, Excellent electrical insulation properties, Heat insulation, heat dissipation is good
(5) FKM: For most of the oil and solvent has the ability of resistance, especially all acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and plant oil
(6) PU: Wear-resisting, resistance to high pressure
4. O ring is suitable for all kinds of mechanical equipment in the prescribed temperature, pressure, and different liquid and gas medium, plays a role of sealing under static or motion.In machine tools, shipbuilding, automobile, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of application of various types of the sealing element.Type O sealing ring is mainly used for static seal and reciprocation seal.When used for rotating seal, only in low speed rotary sealing device.Type O sealing ring is generally installed on the outer circle or within the circle cross section inside the rectangular groove for sealing role.Type O sealing ring in oil resistant, acid and alkali, grinding, chemical erosion environment still have good sealing, damping effect.Therefore, type O sealing ring is the most widely used in hydraulic and pneumatic transmission system of a seal.
10. O-ring design, improper use will accelerate its damage, loss of sealing performance.Experiments show that, such as sealing device design is reasonable, the parts simply raise pressure, will not cause the destruction of the o-ring.Under high pressure and high temperature working conditions, the main reason of the o-ring is the permanent deformation of o-ring material and o-ring have been packed into bite spacing seal clearance, o-ring distortions during movement.
In order to prevent the distortion of the o-ring damage, when the design should pay attention to the following points
(1) O-ring grooves concentricity size installation, should from the processing is convenient and does not produce distortions two aspects to consider.
(2) O-ring section size should be uniform, and in every time when installation should be in a sealed parts thoroughly lubricating oil or grease.Sometimes felt so saturated with the lubricating oil can be used coil refueling device.
(3) Increase the cross section of o-ring diameter, dynamic seal with O ring cross section in diameter should be greater than the static sealing o-ring;In addition, the o-ring should avoid to be used for large diameter of piston seal.
(4) Also produce distortion damage under low pressure, can use seal protection ring
(5) Reduce the surface roughness of the cylinder and piston rod.
(6) With low coefficient of friction materials of O ring
(7) Available to create distortions of sealing ring instead of o-ring
