Importance and Maintenance of Hydraulic Oil Filters


Hydraulic oil filters play a very important role in hydraulic systems. The following is the importance of hydraulic oil filters:

Impurity filtration: There may be various impurities in the hydraulic system, such as metal shavings, plastic fragments, paint particles, etc. These impurities may be generated during the manufacturing process or during use. Hydraulic oil filters can effectively filter out these impurities, prevent them from entering the hydraulic system, and thus maintain the cleanliness of the system.

Protection system components: Components in hydraulic systems, such as valves, pumps, and cylinders, are highly sensitive to impurities. Impurities may cause wear, blockage, and damage to components, thereby reducing the performance and lifespan of the system. By using hydraulic oil filters, system components can be effectively protected and their service life can be extended.

Improving system performance: Clean hydraulic oil can provide better lubrication and sealing effects, reducing friction and leakage. By filtering out impurities, hydraulic oil filters can maintain the quality of oil and improve the performance and efficiency of hydraulic systems.

Preventing malfunctions and maintenance costs: Impurities entering the hydraulic system may cause system malfunctions and shutdowns, requiring a significant amount of maintenance time and cost. By using hydraulic oil filters, the frequency of malfunctions can be reduced, and maintenance and repair costs can be lowered.

Therefore, hydraulic oil filters play a very important role in maintaining the normal operation of hydraulic systems and improving system performance. Regular inspection and replacement of the filter element, maintaining the cleanliness and effectiveness of the oil filter, are key steps to ensure the normal operation of the hydraulic system.

Maintenance method:

Regular replacement of filter element: The filter element is the most critical component in the oil filter and requires regular inspection and replacement. According to usage and manufacturer recommendations, the usual replacement cycle for filter cartridges is 200 to 500 hours. Regularly replacing the filter element can ensure that the oil filter always maintains good filtration performance.

Clean the oil filter: When replacing the filter element, also clean the outer shell and filter screen of the oil filter. You can gently clean with cleaning solution and brush, then wipe dry with a clean tissue. Ensure that the surface of the oil filter is clean and free of oil stains.

Check the pressure differential indicator: Oil filters are usually equipped with a pressure differential indicator to display the degree of blockage in the filter element. Regularly check the pressure differential indicator. When the indicator shows high pressure, it indicates that the filter element needs to be replaced.

Maintenance Record: Establish a maintenance record for the hydraulic system, including the replacement and maintenance of the oil filter. This can better grasp the usage of the oil filter and enable timely maintenance and replacement.

In short, by regularly replacing the filter element, cleaning the oil filter, and checking the pressure differential indicator, the performance and effectiveness of the hydraulic oil filter can be maintained, ensuring the smooth operation of the hydraulic system. Remember to follow the manufacturer’s recommendations and requirements for maintenance and replacement of the hydraulic oil filter.
