The breaker oil seal is an important component in the breaker, mainly used to prevent hydraulic oil leakage and external impurities from entering the hydraulic system. Its structure and principle are as follows:
structure
1. * * Sealing lip * *: The core part of an oil seal, usually made of elastic material (such as rubber), directly contacts the shaft to form a seal.
2. * * Metal skeleton * *: Provides structural support to ensure that the oil seal maintains its shape and stability during installation and use.
3. * * Spring * *: located on the inner side of the sealing lip, used to enhance the elasticity and sealing effect of the sealing lip.
4. * * Dustproof lip * *: located on the outside of the sealing lip, used to prevent external dust and impurities from entering the sealing area.
principle
1. Sealing Function: The sealing lip is tightly attached to the shaft surface under the action of the spring, forming a dynamic seal to prevent hydraulic oil leakage from the gap between the shaft and the oil seal.
2. Dust prevention function: The dust lip prevents external dust and impurities from entering the sealing area, protecting the sealing lip and hydraulic system.
3. Lubrication Function: The interior of the oil seal is usually coated with lubricant to reduce friction between the sealing lip and the shaft and extend the life of the oil seal.
application
Hammer oil seals are widely used in construction machinery, especially in high impact and high vibration environments, to ensure the reliability and longevity of hydraulic systems.
If you need more detailed technical specifications or specific model oil seal information, it is recommended to consult relevant equipment manufacturers or professional technicians.
