O-ring O-ring rubber seal ringCharacteristics and performance?
1. The O-shaped rubber sealing ring has simple structure, good sealing performance, self-sealing effect and reliable sealing performance.
2. O-type rubber sealing ring is easy to install. Because the O-type rubber seal ring itself and the installation site structure are extremely simple, and has been standardized, so the installation and replacement are very easy.
3, O-type rubber sealing ring wide range of application through the selection of appropriate rubber materials and appropriate formula design, to achieve effective sealing of oil, water, air, gas and various chemical media. The temperature range is wide -60 ℃ ~ 220 ℃), and the pressure can reach 1500Kg/cm2 when fixed (used with reinforcing ring).
4. O-type rubber sealing ring is suitable for various kinds of materials, and the size and groove have been standardized.
O-ring rubber sealWidely used in diesel locomotives, automobiles, tractors, construction machinery, machine tools and various hydraulic and pneumatic components such as sealing, can undertake fixed, reciprocating and rotating motion of the seal, in the sealing of mechanical products O-type rubber seals accounted for more than 50%. According to the need, can produce for high temperature, low temperature vacuum, high pressure and different media for a variety of special purpose O-shaped rubber sealing ring, sealing ring and shaped rubber sealing products.
O-ring rubber sealThe characteristics
O-shaped rubber sealing ring is a cross-sectional shape of a circular sealing element, it is widely used in a variety of mechanical equipment, in a certain temperature, pressure and different liquid or gas medium to play a sealing role, compared with other sealing ring, has the following superior performance:
①. The sealing part has simple structure, compact installation part and light weight.
2, a self-sealing effect, often only a seal can complete the sealing effect.
The sealing performance is good, there is almost no leakage when used as a fixed seal, and when used as a moving seal, there is only some leakage when the speed is high.
④, motion friction resistance is very small, for the pressure of alternating occasions can also adapt.
⑤, the size and groove has been standardized, low cost, easy to obtain products, easy to use and purchase.
Compared with other sealing ring, there are also the following three problems:
① The frictional resistance during starting is large.
When used as a seal for pneumatic devices, lubricating oil must be added to prevent wear.
③, the coupling parts, such as the motion surface, groove, gap processing size and precision requirements are very strict.
