Detailed analysis of the wide use of o-ring.
Rubber O-rings are suitable for use in petroleum hydraulic oil, glycol hydraulic oil, diester lubricating oil, gasoline, water, silicone grease, silicone oil and other media. It is currently the most versatile and lowest cost rubber seal. Not suitable for polar solvents such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. The general use temperature range is -40~200 ℃. HNBR hydrogenated nitrile rubber O-ring: It has excellent corrosion resistance, tear resistance and compression deformation resistance. It has good resistance to ozone, sunlight and weather.
Rubber sealing O-rings are widely used for sealing of diesel locomotives, automobiles, tractors, construction machinery, machine tools and various hydraulic and pneumatic components. They can bear the sealing of fixed, reciprocating and rotating movements. In the sealing of mechanical products, O-shaped rubber seals The circle accounts for more than 50%. According to needs, it can produce various special applications for high temperature resistance, low temperature vacuum, high pressure and different media, such as O-shaped rubber sealing rings, sealing rings and special-shaped rubber sealing products. Compared with other types of seals, O-rings have the following advantages:
1. Suitable for various sealing forms: static sealing and dynamic sealing.
2. Suitable materials for various purposes, with standardized dimensions and grooves and strong interchangeability.
3. Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion).
4. Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media.
Through the selection of appropriate rubber materials and appropriate formulation design, an effective sealing effect on oil, water, air, gas and various chemical media is achieved. The temperature range is wide (-60 ℃～+220 ℃), and the pressure can reach 1500Kg/cm2 (used together with the reinforcing ring) in fixed use. The O-ring is simple in design, compact in structure, easy to assemble and disassemble, its cross-sectional structure is extremely simple, and it has a sealing function, and the sealing performance is reliable, so installation and replacement are very easy.
