Project details

Size and shape: The size and shape of the O-ring depend on the size and type of seal required. When designing, it is necessary to consider factors such as the size, shape, and surface roughness of the sealing contact surface, and select appropriate cross-sectional diameter, height, and material based on the pressure, temperature, and other conditions of the sealing medium.

Material selection: The O-ring material should have sufficient elasticity and pressure resistance to achieve good sealing effect. Commonly used materials include rubber, silicone, polyurethane, etc., which need to be selected based on usage conditions and requirements.

Compression rate and stretching amount: The compression rate and stretching amount of the cross-sectional diameter of the O-ring are the main contents of sealing design. A low compression rate can lead to poor sealing effect, while a high compression rate can cause excessive deformation of the O-ring and affect its service life. The stretching amount is also an important parameter that needs to be selected based on the characteristics and usage conditions of the O-ring material.

Groove design: The O-ring needs to be used in conjunction with the groove, and the design of the groove is also the key to sealing. Generally speaking, the width of the groove should be slightly smaller than the diameter of the O-ring, and the depth should be determined based on the height of the O-ring and the required compression rate.
