Project details

An O-ring is a rubber sealing ring with a circular cross-section. Due to its O-shaped cross-section, it is called an O-shaped rubber sealing ring, also known as an O-ring. It has the advantages of cheap price, simple manufacturing, reliable function, simple installation requirements, and can withstand pressure of tens of megapascals (thousands of pounds). Therefore, it is widely used in various mechanical seals, such as the shaft of rotary pumps and hydraulic cylinder pistons.

The O-ring is generally made of rubber material, which can be natural rubber, synthetic rubber, silicone rubber, etc. Its working principle is to rely on its own elasticity and compression deformation to generate a certain amount of pressure on the sealing surface, thereby playing a sealing role.

O-ring seals have a wide range of applications, such as in fields such as machinery, automobiles, ships, petroleum, chemical engineering, etc., and can be used as sealing components. During the manufacturing process, it is necessary to undergo processes such as vulcanization treatment to achieve excellent physical and chemical properties.

When using O-ring seals, the following points need to be noted:

Properly select the material and specifications of the O-ring seal to ensure its fit with the sealing surface and dimensional accuracy.

When installing the O-ring, it is necessary to clean the sealing surface and O-ring to avoid contamination by impurities and grease.

During the installation process, it is necessary to maintain the stability of the shape and size of the O-ring seal to avoid twisting and stretching.

During use, it is necessary to regularly check the wear and aging of the O-ring seal, and replace damaged O-rings in a timely manner.

In summary, O-ring seals are a common type of sealing element with broad application prospects. During use, attention should be paid to material selection, installation, and maintenance to ensure its normal operation and extend its service life.
