Hydraulic Cylinder Filter Requirements

A significant pressure difference may indicate issues such as low oil temperature, high oil viscosity, demulsification of oil, or severe filter element contamination. Prompt action, such as replacing or cleaning the filter element, should be taken based on the specific inspection results.
Regular cleaning and replacement: Clean the filter element at regular intervals to maintain optimal filtration efficiency. The cleaning frequency should be determined based on the frequency of use. If necessary, replace the filter element promptly. 
Purification treatment: Use specialized cleaning equipment to carry out purification treatment, ensuring the hydraulic cylinder operates under normal conditions. This treatment helps remove any contaminants that may have bypassed the filter or accumulated within the system.
Select appropriate filtration precision: Choose the filtration precision based on specific needs. For critical components and sensitive systems like transmission components, servo valves, and proportional valves, high-precision filters should be installed in front of them. This ensures that the oil passing through these components remains within the specified pollution control range.
Additional filtration measures: Install pump oil filters on the main pump oil pipe if the flow rate of the hydraulic cylinder is high. This provides an extra layer of filtration. Additionally, utilize an oil refrigeration system as an independent bypass filter system, which not only filters the oil but also provides cooling functions.
By adhering to these requirements and practices, the hydraulic cylinder filters can effectively remove contaminants and maintain a clean and efficient hydraulic system, promoting optimal performance and extending the lifespan of the hydraulic cylinder.
