Spring-energized seals are widely used in various mechanical equipment due to their excellent sealing properties. Spring-energized seals play an important role in automobiles, ships, aerospace, petrochemicals, electricity, medicine, and other industries.
In these fields, the quality of sealing performance is directly related to the safe operation and service life of the equipment. In addition, let us learn about the main application areas of spring energised seals today.
1. High-temperature sealing
Modern industrial cylinders require high-temperature cylinder seals in many places, such as pressure casting cylinders, metallurgical cylinders, kiln cylinders, automobile engine seals, etc., with a maximum temperature of about 300°C.
2. Low-temperature sealing
Sealing of liquefied nitrogen, liquefied petroleum gas, liquefied carbon dioxide, liquefied oxygen, etc., with a minimum temperature of -200°C.
3. High-pressure sealing
Ultra-large tonnage presses, high-pressure water cutting machines, and air compressors with a maximum pressure of 400 MPa.
4. High-speed sealing
High-speed shafts, with a rotation speed of up to 30-40 meters per second; high-speed reciprocating cylinders, with a telescopic speed of up to 15-20 meters per second.
5. Sealing of special working media
High-temperature water vapor, seawater, brake oil, acid, alkali, etc.
6. Low friction
Typical examples include servo cylinders.
7. Long-life sealing
Wind power pitch cylinders, building shock-absorbing cylinders.
8. Large cylinder sealing
Crane cylinders, forklift cylinders.
9. Hygienic and safe sealing
Currently, many seals that come into contact with food and medicines use spring energised seals.
10. Quick response cylinder
The installation groove of the seal is small, and the various structural parts of the cylinder can be lighter. At the same time, the friction resistance is small, which can greatly improve the dynamic performance of the cylinder and create a better, quicker response.
