Optimization of Lubrication and Sealing Technology for Hydraulic System of Paper Machinery

With the rapid development of the papermaking industry, the performance and efficiency requirements of papermaking machinery are increasingly improving. As an important component of papermaking machinery, the optimization of lubrication and sealing technology in hydraulic systems is of great significance for improving the stability of equipment operation and extending its service life. This article will explore optimization strategies for hydraulic systems in papermaking machinery from two aspects: lubrication technology and sealing technology.

1、 Optimization of lubrication technology

Lubrication technology plays a crucial role in hydraulic systems, as it not only reduces friction and wear, but also lowers energy consumption and temperature, improving the operational efficiency of the system. Based on the characteristics of the hydraulic system of papermaking machinery, we can optimize lubrication technology from the following aspects:

Choose the appropriate lubricating oil: Select the appropriate lubricating oil based on the working conditions, temperature range, load size, and other factors of the hydraulic system. The new lubricating oil should have excellent lubrication performance, antioxidant performance, and anti emulsification performance to ensure that the system can maintain good lubrication status under different working conditions.

Optimizing lubrication methods: Advanced lubrication methods such as centralized lubrication and automatic lubrication are adopted to ensure uniform distribution and timely replenishment of lubricating oil. At the same time, strengthen the monitoring and maintenance of the lubrication system, replace severely worn lubrication components in a timely manner, and ensure lubrication effectiveness.

Control oil temperature: Excessive oil temperature can cause lubricating oil to deteriorate and system efficiency to decrease. Therefore, it is necessary to control oil temperature through cooling devices or improving heat dissipation conditions. At the same time, set the working parameters of the hydraulic system reasonably to avoid excessive oil temperature.

2、 Optimization of sealing technology

Sealing technology is a key measure to prevent hydraulic system leakage, and its performance directly affects the safety and reliability of the system. Based on the characteristics of the hydraulic system of papermaking machinery, we can optimize the sealing technology from the following aspects:

Select high-performance sealing materials: new polymer materials, ceramic materials, and composite materials have excellent corrosion resistance, high temperature resistance, and wear resistance, suitable for various complex working environments. Choosing these high-performance sealing materials can significantly improve the performance and service life of seals.

Optimize sealing structure: Based on the pressure and flow parameters of the hydraulic system, design the shape, size, and sealing surface structure of the sealing components reasonably. At the same time, considering factors such as wear and leakage of seals, appropriate compensation measures should be taken to ensure the sealing effect.

Strengthening the installation and maintenance of seals: The installation quality of seals has a significant impact on the sealing effect. During the installation process, it should be ensured that the cover is clean and flat, avoiding scratches and deformation. At the same time, strengthen the maintenance and inspection of seals, replace severely worn seals in a timely manner, and ensure the sealing performance of the system.

In summary, the optimization of lubrication and sealing technology in the hydraulic system of papermaking machinery is an important means to improve equipment performance and stability. By selecting appropriate lubricants, optimizing lubrication methods, controlling oil temperature, selecting high-performance sealing materials, optimizing sealing structures, and strengthening the installation and maintenance of sealing components, the operational efficiency and safety of hydraulic systems can be significantly improved, providing strong support for the sustainable development of the paper industry.
