The following measures can be taken to improve the sealing performance of the piston rod:
1. Choose the appropriate sealing element: Use high-quality sealing elements such as O-rings and sealing gaskets, and choose materials that are wear-resistant, oil resistant, and temperature resistant to ensure a good fit between the sealing element and the piston rod.
2. Surface treatment: Conduct surface treatment on the piston rod, such as chrome plating, grinding and polishing, to improve surface smoothness and smoothness, and reduce leakage between the sealing element and it.
3. Lubricating oil film: forms a lubricating oil film between the piston rod and the sealing element, reducing friction and wear, and improving sealing performance. Suitable lubricating oil or grease can be used to ensure the normal operation of the oil supply system.
4. Control working temperature: Its working temperature has an impact on sealing performance. Reasonably control the working temperature to avoid aging and deformation of seals caused by high temperatures, as well as hardening and failure of seals caused by low temperatures.
5. Regular maintenance and inspection: Regularly check the wear of the piston rod and sealing components, and promptly replace severely worn sealing components to ensure good sealing performance.
6. Pay attention to the usage environment: avoid contact with corrosive media or particulate impurities, and maintain a clean and smooth surface.
By taking the above measures, the sealing of the piston rod can be improved, ensuring the normal operation of the hydraulic system.
