The hydraulic oil filter element is used in the hydraulic system to filter out solid particles and colloidal substances in the working medium, which can effectively control the pollution degree of the working medium, protect the safe operation of the machine, and prolong the life of the machine.

How often is the hydraulic oil filter replaced? Under normal circumstances, the replacement period of the hydraulic oil suction filter is replaced every 2000 hours. The replacement period of the hydraulic return filter is 250 hours for the first time, and then replaced every 500 hours. If it is a steel mill, the working environment is rather bad. Changing the filter element too frequently will affect the production. It is recommended to periodically take the hydraulic oil sample and send it to check the cleanliness of the liquid, and then determine a reasonable replacement cycle.

When replacing the hydraulic oil filter, check the bottom of the filter element for metal particles or debris. If there is copper or iron filings, the hydraulic pump, hydraulic motor or valve may be damaged or damaged. If there is rubber, the hydraulic cylinder seal is indicated. damage.
