The differences and connections between lip seals and skeleton oil seals

1. Basic concepts of lip seals and skeleton oil seals

Lip seals and skeleton oil seals are both types of oil seals used to reduce liquid or gas leakage. Lip seals are generally made of materials such as rubber or plastic. They are shaped like a "U" and can be used to seal liquids. Skeleton oil seal is a sealing element used in power transmission equipment and machinery. It is generally made of an elastic material coated with a metal skeleton and can be used to seal liquids and solid particles.

2. The structural difference between lip seal ring and skeleton oil seal

The structure of the lip seal is simpler than the skeleton oil seal, consisting of an inner membrane, a lip, and an outer membrane. Among them, the lip part is the key part of the sealing ring, which is used to contact the object to be sealed and play a sealing role. The skeleton oil seal is composed of a spring, an outer sleeve, and an inner sleeve. The skeleton is a key part and can withstand centrifugal force and axial force to ensure the reliability of the seal.

3. Application areas of lip seals and skeleton oil seals

Lip seals are mainly used in automobiles, machinery, electronic instruments, petroleum and other industries. They are used to seal liquids or gases and have the functions of dustproof, waterproof and sound insulation. The skeleton oil seal is mainly used in power equipment such as machine tools, compressors, and gear boxes. It is used to seal lubricating oil and hydraulic oil, etc., and has the functions of dustproof, waterproof, and anti-corrosion.

4. The main relationship between lip seal ring and skeleton oil seal

Lip seals and skeleton oil seals are both seals and have the function of sealing liquid or gas. In addition, both the lip seal ring and the skeleton oil seal need to be installed according to the prescribed installation methods to ensure their sealing performance.

To sum up, there are structural differences between lip seals and skeleton oil seals, but they both play a sealing role and have similarities. Lip seals are mainly used to seal liquids or gases, and skeleton oil seals are mainly used in power transmission equipment and machinery to seal lubricating oil and hydraulic oil. Whether it is a lip seal or a skeleton oil seal, it needs to be installed according to the prescribed installation method to ensure its sealing performance.
