O-ring is a circular rubber ring section, because of its cross-section O-type, so called O-ring.
O-rings are suitable for use in a variety of mechanical equipment, in the specified temperature, pressure, and different liquid and gas medium, in the static or moving state from the sealing effect. Molded O Ring In the machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, Molded O Ring agricultural machinery, and various instruments, a large number of applications of various types of seals element. O-rings are mainly used for static and reciprocating seals. For rotary motion seals, only for low speed rotary seals. O-ring is generally installed in the outer or inner circle on the rectangular cross-section of the seal from the role. O-ring in the oil, acid, grinding, chemical erosion and other environments still play a good seal, shock absorption. Therefore, the O-ring is the hydraulic and pneumatic transmission system used in the most extensive seal.
O-ring is a circular shape of the sealing element, Molded O Ring it is widely used in a variety of mechanical equipment, in a certain temperature, pressure and different liquid or gas medium to play a sealing effect.
Compared with other seals, with the following superior performance:
①, sealed parts of the structure is simple, compact installation, and lighter weight.
②, self-sealing effect, often only one seal will be able to complete the sealing effect.
③, good sealing performance, used as a fixed seal when almost no leakage, used as a sports seal, Molded O Ring only when the speed is high when some leakage.
④, movement friction resistance is very small, for the occasion of the pressure can also be adapted.
⑤, size and groove has been standardized, low cost, easy to use, easy to use and outsourcing.
O-ring in the rubber material standard, the hardness and compression of the two permanent performance of the most important weight. The choice of rubber material with smaller compression deformation is beneficial to the sealing performance, and the hardness is critical to the pressure and resistance to the O-ring. According to domestic standards and practical experience, rubber at the specified temperature of the maximum compression deformation of not more than 50%.
