The application scope and advantage of wear-resistant O-ring
Author:
Wear-resistant O-ring is a kind of rubber ring with circular section. Because its section is O-shaped, it is also called O-shaped rubber ring, also known as O-ring. It first appeared in the mid-19th century as a sealing element in steam engine cylinders. Next, let's take a look at the application scope and advantages of wear-resistant O-ring. Use scope and advantage
I. Application range of wear-resistant O-ring
Wear-resistant O-ring is used to install on a variety of mechanical equipment, can be in static conditions or in the specified temperature, pressure and different liquid, gas medium motion plays a sealing role. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery and various instruments and meters. o - ring is mainly used for static sealing and reciprocating sealing. For rotary motion seals, only low speed rotary seals. The O-ring is generally installed in the groove of the outer circle or the inner circle with a rectangular upper section, which acts as a seal. O-ring in oil, acid, alkali, grinding, chemical erosion and other environments can still play a good sealing and damping role. Therefore, the O-ring is a widely used seal in hydraulic and pneumatic transmission systems.
Two, wear-resistant O-ring advantages
O-type sealing ring compared with other types of sealing ring, has the following advantages:
1, wear-resistant O-ring is suitable for various forms of seal: static seal, dynamic seal.
2, wear-resistant O-ring is suitable for a variety of applications of materials, size and grooves have been standardized, strong interchangeability.
3, wear-resistant O-ring is suitable for all kinds of motion: rotary motion, axial reciprocating motion.
4, wear-resistant O-ring is suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media.
5, through the selection of a suitable rubber composite material and the appropriate formula for design, to achieve the oil, water, air, gas and a variety of learning chemical reaction medium can effectively seal the system. Wide range of temperature and use management (-60℃ ~ +220℃), fixed use of working pressure up to 1500Kg/cm2(combined with reinforcing ring).
6, the design is simple, the structure is more compact, convenient installation and disassembly.
7, o ring type segment structure is extremely simple, with self-sealing effect, reliable sealing performance.
8, because the installation of the O-ring itself and the structure is extremely simple, and has formed a standardized, so the installation and replacement are very easy.
9, material variety, according to different fluid selection of nitrile rubber, FKM, VMQ, EPDM, neoprene rubber, butyl rubber, polytetrafluoroethylene, natural rubber, etc.
10. Low cost.
11, the dynamic friction resistance is relatively small.
