Three, O-ring applications O-ring is mainly used for static seals and reciprocating seals. For rotational movement of the seal when limited to low-speed rotary sealing device. O-ring seals in oil is generally mounted on the outer or inner circular cross-section of the inner rectangle from the seal groove. O-ring seals in the oil, acid, wear, erosion and other environmental chemistry still play a good sealing, damping effect on machine tools, shipbuilding, automotive, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery on petroleum machinery, plastic machinery, agricultural machinery, and a variety of instruments, large-scale application of various types of sealing elements. Compared with other sealing element, O-ring on the circular cross section within the rectangular groove from the seal. O-ring seals in the oil, acid, wear, erosion and other environmental chemistry still has a wide range of advantages from: - for a variety of seal forms: static seals, dynamic seals for a variety of uses materials, dimensions and grooves are standardized, interchangeability - for a variety of movement: the rotational motion, or a combination of axial reciprocating movement (such as rotating reciprocating movement combinations) - suitable for a variety of different sealing medium: oil, water, gas, chemical, or other mixed media By choosing a suitable medium oak circular cross-section from the seal inside the rectangular grooves. O-ring seals in the oil, oil, acid, wear, erosion and other environmental chemistry from the plastic material and is still appropriate formulation design, implementation, oil, water, air, gas, and various chemical mediators effective seal. Wide temperature range (- 60 ℃ ~ + 220 ℃), fixed using a pressure of up to 1500Kg / cm2 (with reinforcement ring and use). - Designed to be simple O-ring cross section structure is extremely simple, and there is self-sealing, reliable sealing performance. - Easy installation due to O-ring structure itself and the installation site is extremely circular cross-section from the seal on a rectangular trench. O-ring, oil, acid, wear, erosion and other environmental chemistry still played in is simple, and has become standardized, so the installation is very easy to replace. - Low cost - material varieties can be selected depending on the fluid: There nitrile rubber (NRB), Viton (FKM), silicone rubber (VMQ), ethylene-propylene rubber (EPDM), chloroprene rubber (CR) , butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR) and other O-ring material classification controls and the advantages and disadvantages: 1, natural rubber NR (Natural Rubber) from the rubber tree harvest seals in oil, set made of latex, isoprene polymers. Having good wear resistance, high elasticity, tensile strength and elongation. Circular cross section for the inner rectangle from the seal groove. O-ring seals in the oil, acid, wear, erosion and other environmental chemistry still played easy to aging in the air, when heated, becomes sticky, easy expansion and dissolved in mineral oil or gasoline, but the impatience of acid and alkali. ? Is the production of belts, hoses, rubber raw materials, and for the production of shock absorber parts, from the seal groove using a rectangular cross-section in a circle with a hydroxide liquid automotive brake oil, ethanol, etc. for. O-ring seals in the oil, acid, wear, erosion and other environmental chemical products still played. 2, the SBR SBR butadiene styrene copolymer, compared with natural rubber, uniform quality, less foreign body, but the mechanical strength is weak, with a circular cross-section moment of seals in the oil, shaped ditch tank acts as a seal. O-ring seals in the oil, acid, wear, erosion and other environmental chemistry from natural rubber blends still use. Advantages:??? Low-cost non-oil-repellent material of good water resistance, hardness of 70 or less with good elastic compression high hardness with less distortion can be used most of the neutral circle of chemicals and a rectangular cross section? trench acts as a seal. O-ring seals in the oil, acid, wear, chemical erosion and other environmental seals in accordance with the oil, then from dry, Zi of organic ketone Disadvantages:? Not recommend the use of strong acid, ozone, oils, and fats and oils ester Most of the hydrocarbons being. ? Widely used in the tire industry, footwear,? Cloth industry and conveyor industries. Butyl rubber IIR (Butyl Rubber) for polymerization of isobutylene and a small amount isoprenes, retain a small amount of saturated sulfur does not fit the base for use, due to steric hindrance of methyl movement less than other polymer molecules, so less gas permeability , heat, sunlight, ozone resistance of large, good electrical insulation; polar solvents such as alcohols circular cross-section for the inner rectangle from the seal groove. O-ring seals in the oil, acid, wear, erosion and other environmental chemistry still played, ketones, circular cross-section from the seal on a rectangular trench. O-ring seals in the oil, acid, wear, chemical erosion and other environmental seals in oil, still great resistance from esters, the general temperature range of -54 ~ 110 ℃. o-ring supplier
