The widespread use of O-rings depends on the leadership of rubber ring sealing technology in the field of modern industrial sealing technology. At present, all plant equipment, including daily necessities are generally used O-type rubber seals. O-type rubber seal came about half a century, Molded O Ring at home and abroad has gradually formed a complete design, processing system. Because of its simple geometric shape, mold manufacturing process is relatively easy, low cost, the basic product to meet the needs of conventional sealing technology, with good economy.
Is a circular shape of the sealing element, it is widely used in a variety of mechanical equipment, Molded O Ring 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, the installation site is compact, and lighter weight.
②, self-sealing effect, Molded O Ring 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, Molded O Ring used as a sports seal, 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-rings are suitable for use in a variety of mechanical equipment, Molded O Ring in the specified temperature, pressure, and different liquid and gas medium, in a static or moving state from the sealing effect. In the machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, 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, Molded O Ring chemical erosion and other environments still play a good seal, shock absorption. Therefore, the O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.
