HOW TO USE SING SPRING SEALS?

The spring energy storage sealing ring is composed of a polymer material sealing shell and a corrosion-resistant stainless steel metal spring. There are many types of metal springs to choose, including O-shaped springs, V-shaped springs, and U-shaped springs, which meet the sealing requirements of different movement forms. In some occasions, O-rings of different materials can be used as elastomers instead of metal springs. Spring seals provide durable and reliable sealing solutions in critical applications and under extreme operating conditions in different industries.

Working principle of sing sealing ring

The sealing ring is installed in the groove, and the spring is compressed to form an outward tension, which promotes the sealing lip to close to the sealing groove. Because the spring permanently provides elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the matching parts Sealing from vacuum to low pressure. In addition, the system pressure will assist the spring energy storage. The greater the pressure is, the more fully the sealing lip fits the groove, thereby forming a high-pressure seal.

The sealing shell is made of PTFE, filled PTFE, PEEK, filled PEEK, PVDF, PPS or other high-performance polymer materials through mechanical processing, the material determines the spring energy storage sealing ring is suitable for the temperature range from -268 ℃ to +427 ℃ Inside, seal almost all liquids, chemicals and gases. And it can be stored indefinitely without aging problems.

Use of sing sealing ring

Excellent physical and technical characteristics make spring seals ideal for a variety of key industrial equipment and applications. Spring seals can be used for both dynamic and static applications. Dynamic applications include reciprocating motion (linear), rotary motion and oscillating motion or any combination. When deciding whether to use standard polymer seals or spring-activated seals, the following factors should be considered:

Temperature (maximum / minimum possible in work and environment)

Working pressure (not necessarily the maximum pressure in the system)

Speed (moving speed)

Media (chemical compatibility, especially important for corrosive media)

Friction level and wear

Environment (for example, abrasive conditions)

Application and operation of equipment

Sealed cavity configuration

Shelf life limitation

Advantages of sing sealing ring

1. The sealing ring should have good sealing performance within the working pressure and a certain temperature range, which can automatically improve the sealing performance as the pressure increases.

2. The friction force between the sealing ring device and the moving parts should be small, and the friction coefficient should be stable.

3. The sealing ring is characterized by strong anti-corrosion ability, not easy to aging, long working life, good wear resistance, and can automatically compensate to a certain extent after wear.

4. The structure is simple and easy to use and maintain, so that the seal ring has a longer life.
