What are the performance requirements of hydraulic rubber seals?

Hydraulic rubber seal ring is the basic component of mechanical products, and all hydraulic products can not be separated from it, rubber seal ring is widely used in automobiles, motorcycles, construction machinery, shield machine, general machinery. People who do not know will ask what is the role of the seal ring? Haisheng rubber tells you that its use is to prevent liquid leakage, prevent air and pollutants from entering the system and components to cause oil pollution, and to improve product efficiency and performance.

The use of hydraulic rubber seals must meet the following performance requirements:

1. The friction resistance should be small: to avoid or reduce the adverse phenomena such as low pressure crawling of hydraulic equipment;

2. Good compatibility: Because the rubber sealing ring is immersed in the hydraulic oil for a long time, it is easy to swell, dissolve or embrittlement and harden, so that it loses the sealing effect, so the sealing ring design is required to have good compatibility with the hydraulic oil;

3. The leakage amount is very small when used: the leakage amount of the rubber sealing ring is required to be very small, and has a good sealing effect, and with the increase of pressure, improve the sealing effect;

4. Long service life: the hydraulic rubber sealing ring needs to have good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength, and long service life.

We make good use of hydraulic rubber seals to avoid bad phenomena in equipment, hydraulic rubber seals also have good compatibility, when designing seals, we should allocate good rubber properties according to their working environment. Good use of hydraulic rubber seals will also make it work, there will be no leakage, can make the service life of the seal longer.
