The wide use of O-ring depends on the leading position of rubber ring sealing technology in the field of modern industrial sealing technology. At present, the various plant equipment, including daily necessities are widely used O-type rubber seal ring. O-Ring came out about half a century ago, Molded O Ring at home and abroad has gradually formed a complete design, processing system. Because of its simple geometric shape, mold setting manufacturing process is relatively easy, low cost, the product basically meet the needs of conventional sealing technology, has good economic.
O-Ring sealing excellent performance, high working life, dynamic pressure seal working life than conventional rubber seal products 5-10 times higher, up to dozens of times times, Molded O Ring in some conditions can be with the sealing matrix with the same life.
O-Ring friction resistance is small, dynamic, friction equal, is "0" rubber ring friction/, can eliminate low-speed, low pressure movement "crawling" phenomenon.
O-Ring high wear-resistant, sealing surface wear after the automatic elastic compensation function.
O-Ring good self-lubricating performance. Molded O Ring Can be used as oil-free lubrication seal.
O-Ring structure is simple, easy to install.
O-Ring working pressure: 0-300MPA; working speed: ≤15m/s; working temperature:-55-250 degrees.
O-Ring applicable medium: Hydraulic oil, gas, water, mud, crude oil, emulsion, water-glycol, acid.
The O-ring is suitable for loading on a variety of mechanical equipment, in the specified temperature, pressure, and different liquids and gas medium, in the static or moving state of the sealing effect. In Machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, Molded O Ring and various types of instrumentation, a large number of applications of various types of sealing elements. O-rings are mainly used for static seals and reciprocating motion seals. For rotating motion seals, it is limited to low-speed rotary seals. O-ring is generally installed in the outer circle or the inner circle with a rectangular groove inside the trench sealing effect. O-Ring in the oil-resistant, acid-base, grinding, Molded O Ring chemical erosion and other environments still play a good sealing, damping effect. Therefore, O-ring is one of the most widely used seals in hydraulic and pneumatic transmission systems.
O-Ring compared with other types of seals, has the following advantages: suitable for a variety of sealing forms: static seal, dynamic seal
Suitable for all kinds of materials, size and groove has been standardized, interchangeability is strong-suitable for a variety of sports: rotational movement, Molded O Ring axial reciprocating movement or combination of movement (such as rotating reciprocating combination movement)
Suitable for a variety of different sealing media: oil, water, gas, chemical medium or other mixed medium
The effective sealing effect of oil, water, air, gas and various chemical mediums can be achieved by selecting suitable rubber material and proper formula design. The temperature range is wide (-60℃~+ 220 ℃) and the pressure can reach 1500kg/cm2 (with the reinforcement ring) when fixed.
Simple design, compact structure, easy to disassemble
O-Ring section structure is extremely simple, and has a self sealing effect, sealing performance is reliable.
Because the O-ring itself and the installation of the structure are extremely simple, Molded O Ring and has become standardized, so the installation of replacement is very easy.
Many kinds of materials
Can be selected according to different fluids: there are NBR (NBR), fluorine rubber (FKM), Silicone Rubber (VMQ), ethylene propylene Rubber (EPDM), Neoprene (CR), Butyl Rubber (BU), PTFE (PTFE), Natural Rubber (NR), etc.--low cost--the relatively small dynamic friction resistance
