Sealing principle of hydraulic seals

2024 11/22

O-ring seals used in combination with oil seals are generally made of rubber sealing material, with a simple sealing ring structure, good sealing performance, and low friction. It can be used for linear reciprocating and rotary motion, but is more commonly used for fixed sealing, such as sealing of pipelines, cylinder heads, and cylinder sleeves. Or applicable to low-level, non critical components.
In daily operation, fatigue of hydraulic equipment will always exist, so it is necessary to stop regularly for inspection and maintenance during the operation process. The cylinder barrel of the oil cylinder seal often needs professional maintenance, repair, and upkeep to improve the self service life and sealing performance of the oil cylinder seal. So, what is the correct maintenance and upkeep work for the rubber seals of the oil cylinder?
1. The hydraulic cylinder of the sealing element needs to be regularly replaced with hydraulic oil, the filter screen should be cleaned, and the cleanliness standard should be ensured;
2. When using hydraulic cylinder equipment, the system temperature must be adjusted to avoid affecting the service life of the seals;
3. It is necessary to eliminate the air in the system and preheat each system to avoid cylinder failure;
4. Regularly inspect the bolts and threads of each connecting system to avoid loosening and causing malfunctions;
5. And pay attention to keeping the oil components lubricated to avoid dry friction;
6. Protect the outer surface of the piston rod to prevent damage to the seal caused by bumps and scratches, and clean the dust ring of the oil cylinder dynamic seal and the exposed mud and sand on the piston rod.
