To ensure the long-term normal operation of hydraulic cylinder filters, several requirements should be met during daily use:
Regularly check the import and export pressure difference of the hydraulic cylinder filter. A significant pressure difference may indicate low oil temperature, high oil viscosity, oil demulsification, or severe filter element contamination. In such cases, the filter element may need to be replaced or cleaned, and the issue should be addressed promptly. A small pressure difference may be caused by a penetrated filter element, improper installation of the filter inlet and outlet bypass valve, or insufficient oil flow.
Maintain regular cleaning to ensure optimal filtration effectiveness. Determine the cleaning cycle based on the frequency of use, and replace the filter element when necessary. Additionally, clean the filter housing regularly.
Perform purification treatment using specialized cleaning equipment. This level of cleaning ensures the hydraulic cylinder's normal operation and should be carried out as needed.
Choose an appropriate filtration precision based on specific requirements. For instance, high-precision filters are typically installed in front of hydraulic cylinder pressure pipes or high-precision components like transmission components, servo valves, and proportional valves. This helps control the environmental pollution level of oil passing through these components within specified limits.
Install a pump oil filter on the main pump oil pipe if the hydraulic cylinder has a high flow rate. Additionally, an oil refrigeration system can be employed as an independent bypass filter system, providing both cooling and filtering functions.
By following these guidelines, the hydraulic cylinder filter can maintain its performance over an extended period, ensuring efficient and reliable operation of the hydraulic system.
