Oil resistance of NBR sealing ring and its application in hydraulic system
NBR sealing ring is a kind of sealing product made of Nitrile Butadiene Rubber as the base material, which is widely used in hydraulic systems because of its excellent oil resistance. In this paper, the oil resistance characteristics of NBR seals and their important applications in hydraulic systems will be discussed in detail.
- Oil resistance of NBR sealing ring
NBR seals are favored in hydraulic systems because of their excellent oil resistance:
Excellent oil resistance: NBR seals can work stably in hydraulic oil, lubricating oil and other liquid media for a long time, and will not expand or soften due to oil contact.
Strong anti-aging ability: NBR material has good oxidation resistance and heat resistance, can maintain stability in high temperature and high pressure environment, and is not easy to aging and deterioration due to environmental factors.
Stable physical properties: The NBR seal can maintain its original physical properties in the oil environment, such as elasticity, sealing and wear resistance, to ensure long-term stable operation of the system.
- Application scenario of NBR sealing ring in hydraulic system
Due to its excellent oil resistance and stable physical properties, NBR seals are widely used in hydraulic systems:
Hydraulic cylinder seal: In the piston seal and piston rod seal of the hydraulic cylinder, the NBR seal ring can effectively prevent the leakage of hydraulic oil and ensure the working stability and efficiency of the hydraulic system.
Body seal: In hydraulic body and valve seals, NBR seals play a key role in ensuring that the individual valves of the hydraulic system can accurately control and regulate the flow of fluid.
Pump body seal: In the hydraulic pump body and pump seals, the NBR seal ring can effectively prevent the leakage of hydraulic oil inside and outside the pump to ensure the long-term stable operation of the pump.
- Precautions and maintenance suggestions
In order to maximize the performance of the NBR seal in the hydraulic system, the following matters need to be noted:
Correct selection of sealing ring specifications: According to the working pressure, temperature and medium of the hydraulic system, select the appropriate NBR sealing ring specifications and models.
Regular inspection and replacement: Check the status of NBR seals regularly, such as aging, wear or hardening, and replace them in time to avoid leaks and system failures.
Avoid excessive stretching and damage: Avoid excessive stretching or mechanical damage to the NBR seal during installation and use to maintain its long-term sealing effect.
- Conclusion
In summary, NBR seals, with their excellent oil resistance and stable physical properties, are an indispensable and critical component of hydraulic systems. This paper discusses the oil resistance of NBR seal ring and its application in hydraulic system in detail, hoping to provide practical information and guidance for manufacturers and users of hydraulic equipment to ensure the safe operation and long-term reliability of the system.
