What are the factors affecting the sealing performance of hydraulic cylinders?

The sealing performance of the hydraulic cylinder is important for the normal operation of the hydraulic system. 

There are many factors that affect the sealing performance of the device, including the following main factors:

       1, the quality of seals: sealing performance is directly affected by the quality of seals. Seals include seals, sealing gaskets and O-rings. 

Select high-quality seals to ensure its anti-wear, oil, temperature and other properties to improve sealing performance.

       2, the quality of hydraulic oil: the use of qualified hydraulic oil is important for sealing performance. 

Low quality or contaminated hydraulic oil may cause damage to the seals, thus reducing sealing performance.

       3, the processing quality of the sealing surface: the sealing surface inside the hydraulic cylinder needs to be kept flat and smooth. 

If the sealing surface has defects, depressions or wear, it will lead to the seals can not work properly, thus affecting the sealing performance.

       4, the installation of seals: the correct installation of seals is very important. 

Incorrect installation may lead to seal or gasket damage, resulting in leakage. Ensure that the seals are properly installed and maintain an even distribution of pressure.

       5、Operating temperature: Temperature has a significant impact on sealing performance. 

High temperatures may cause the seal to harden and deform, thus weakening the sealing performance. 

Low temperatures may make the seal become weak and prone to rupture. It is important to choose seals suitable for the operating temperature range.

       6, working pressure: high pressure will increase the working load of the device, the sealing performance put forward high requirements. 

Therefore, it is necessary to select the seals suitable for the working pressure range to avoid leakage.

       7, the nature of the medium: different hydraulic media (such as hydraulic oil or hydraulic fluid) has different properties, including viscosity, chemical properties and corrosion.

 Seals must be compatible with the hydraulic medium to ensure long-term sealing performance.

       8, vibration and shock: vibration and shock loads in the hydraulic system may have a negative impact on sealing performance. 

Appropriate design and material selection can mitigate these effects.

       9, maintenance and maintenance: regular maintenance and maintenance is important to maintain the sealing performance of the hydraulic cylinder.

Check the seals for wear and damage, and replace damaged seals in a timely manner to ensure the stability of the system.
