1. Basic functions of rubber seals

2. Factors affecting sealing effect

The seal's ability to seal will be directly impacted by its size and shape. Leakage might occur from improper design if the seal does not fit the sealing surface entirely. A multi-lip design, for instance, can enhance the sealing effect and expand the contact area.

Rubber seal performance will be impacted by variations in the working environment's temperature and pressure. To guarantee that a satisfactory sealing effect can be maintained in harsh conditions, the material's pressure-bearing capability and thermal expansion properties should be taken into account during design.

3. Design improvement suggestions

By improving the material composition throughout the design process, rubber seals can function better. For instance, rubber's oxidation resistance and durability can be increased by adding anti-aging or strengthening chemicals. This not only prolongs the seal's useful life but also keeps the sealing effect intact in a range of conditions.

Multi-lip design

In some situations, conventional single-lip seals might not be sufficient to fulfill the sealing requirements. Consequently, the sealing effect may be further enhanced by using a multi-lip design. More contact points and efficient gas or liquid leak prevention are possible with the multi-lip construction.

Fluid dynamics may be taken into consideration while constructing rubber seals in order to improve the shape. A trapezoidal cross-section design, for instance, can lower fluid eddy currents and lower the possibility of leaks. The sealing effect can also be enhanced by a suitable seal height to breadth ratio.
