Rubber sealing ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent oil leakage and invasion of external objects.
1. O-type sealing ring series
With fluorine rubber, butyronitrile, silica gel, a variety of materials such as ethylene propylene rubber, fluorine rubber products, widely used in all kinds of machinery, all kinds of petroleum base oil and various chemical medium resistance: don't use analysing can satisfy to 60 ℃ to + 200 ℃ (double fluoro rubber FFKM after vulcanization in a certain way can reach more than 300 degrees), the temperature of the area, using the pressure range: < 10 mpa (hydraulic), < 1 mpa (pneumatic) < 16 mpa (static seal) butyronitrile and gasoline resistance (90,93,97) inflation rate is 0.
2. Y-type sealing ring
It is widely used in hydraulic, mechanical, pneumatic and other industries. Kind of petroleum base oil has excellent abrasion resistance, resistance to choose different analysing can satisfy to 60 ℃ to + 200 ℃ temperature area.
3.V seal ring
The utility model relates to an elastic rubber seal ring with axial action, which is used as a non-pressure seal for a rotating shaft. The sealing lip has the better activity and the adaptability, may compensate the big tolerance and the Angle deviation, may prevent the internal grease or the oil liquid leakage outward, also may prevent the outside splashing water or the dust invasion.
4. Use YX type sealing ring for the hole
Application: used for sealing piston in reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinder, hydraulic cylinder of general equipment. CPU: hydraulic cylinder, high temperature and high pressure oil cylinder for construction machinery. Material: polyurethane TPU, CPU, rubber product hardness: HS85 plus or minus 2 ° A working temperature: TPU: - 40 ~ + 80 ℃ CPU: - 40 ~ + 120 ℃ with pressure: 32 mpa working medium or less: hydraulic oil, the emulsion
5. Baffle ring for YX type hole
Simply described product use: this standard is suitable for the cylinder pressure is greater than 16 mpa when used with YX type sealing ring, or eccentric cylinder force, the role of protecting seal. Working temperature: - 40 ~ + 100 ℃ working medium: hydraulic oil, emulsion, hardness of aquatic products: HS92 + / - 5 a material: teflon
Features and materials
Rubber sealing ring is used to install in various mechanical equipment, in the specified temperature and pressure and different liquids and gases, in the static or movement of the sealing role
▶Material analysis of rubber seal ring
1.Use 0 ℃ to + 250 ℃ environment, strong oxidant, oil resistant, resistant to acid and alkali resistance. Usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment. Due to various excellent properties, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.
2. silicone rubber: has outstanding resistance to high and low temperature performance, in - 70 ℃ to + 260 ℃ temperature range to maintain good flexibility, and has the advantages of resistance to ozone, weather aging, appropriate for the thermal mechanical seal gasket. Because there is no toxicity can be made insulation, insulation products and medical rubber products.
3, nitrile butadiene rubber: with excellent oil resistance and aromatic solvents and other properties, but not resistant to ketone, ester and chlorinated by the medium, so oil resistant sealing products to use nitrile butadiene rubber.
4, neoprene: has good oil resistance, solvent resistance, chemical media and other properties, but not resistant to aromatic oil, which is characterized by weather aging and ozone aging properties. Chloroprene rubber is usually used in the production of doors and Windows sealing strips and diaphragm and general vacuum sealing products;
5, epdm: with good temperature resistance, weather resistance aging and ozone aging performance, usually doors and Windows sealing strip, the most widely used in the automotive industry.
6, ptfe composite gasket is based on ptfe and high-quality full into the rubber material, the use of special manufacturing process and become a new type of sealing material, it integrated the excellent characteristics of teflon and rubber, make the product possesses excellent corrosion resistance, and high temperature resistance, non-toxic, viscous resistance, but also has good elasticity and tightness.
