The use of the seal ring is very wide, whether it is large mechanical equipment or mini appliances, you can find it. The choice of sealing rings varies according to the purpose. What factors should be considered in the selection of sealing rings? Let's study together.

1. Working medium and working conditions

When selecting the sealing ring material, we must first consider whether it is compatible with the working medium. Secondly, consider the pressure, temperature, continuous working time, operating cycle and other working conditions of the seal. If the application requires rotation, the friction temperature rise caused by rotation should also be considered.

2. Sealing form

Sealing ring according to the load type can be divided into dynamic seal and static seal, according to the use can be divided into rotary shaft seal, hole seal and shaft seal, according to the installation can be divided into axial installation or radial installation. Different sealing forms and installation conditions are different, you need to choose your own sealing form.

3. Material hardness

The hardness of the sealing ring material is often closely related to the working pressure, clearance value, application, and surface processing quality. If it is a standardized application environment, the material hardness can be Xiao A70. If the environment is high pressure or needs to withstand pulse pressure, use a higher material.

In summary, the selection of sealing rings should consider the working medium, working conditions, sealing form, material hardness.
