Hydraulic oil filter is an indispensable component in the hydraulic system, and its role is to filter out solid particles, colloidal substances and other pollutants in the hydraulic oil to protect the hydraulic system from damage caused by pollution. In order to extend the service life of hydraulic oil filter element, it is necessary to carry out comprehensive policies from multiple angles. The specific analysis is as follows:
1. Control the pollution degree of hydraulic oil
(1) Regularly check the hydraulic oil: It is important to maintain the cleanliness of the hydraulic oil, because the pollution of the hydraulic oil directly affects the life of the filter element. Check the hydraulic oil quality regularly and replace it in time to ensure the cleanliness of the oil.
(2) Avoid pollutant intrusion: Reducing external pollutants into the hydraulic system can reduce the burden of the filter element, thereby extending its service life. Ensure that the seals do not leak, and take measures to prevent pollution sources such as environmental dust from entering the system.
2. Set the filtering accuracy reasonably
(1) Matching filtration accuracy: Select the filter element with appropriate filtration accuracy according to the actual working conditions and requirements of the hydraulic system. Too high filtration accuracy may lead to frequent clogging of the filter element, and too low can not effectively filter pollutants.
(2) Optimize the system design: consider the appropriate configuration of the filter element in the system design to avoid unreasonable increase in the burden and loss of the filter element due to the system design.
3. Maintenance and maintenance of filter element
(1) Timely replacement of the filter element: according to the use of the equipment and the manufacturer's recommendations, develop a reasonable replacement cycle of the filter element, and replace it in time to avoid performance degradation due to the extended use of the filter element.
(2) Regular cleaning of the filter element: when replacing the hydraulic oil, the filter element is cleaned, and the special detergent is used and cleaned in the correct way to remove the pollutants attached to the filter element and restore some of its filtration function.
4. Replacement and supplement of hydraulic oil
(1) Ensure the quality of hydraulic oil: use the specified model and brand of hydraulic oil according to the requirements of the manufacturer, and avoid mixing different labels or brands of oil to prevent oil deterioration and flocculation.
(2) Correct refueling and exhaust: Use a filter to filter the new oil when refueling, and pay attention to the fuel tank to the standard position. After filling the oil, pay attention to remove the air in the system to avoid damage to the main pump by cavitation phenomenon.
5. Filter storage and environmental protection
Avoid leaving the filter cartridge empty for a long time: If the filter cartridge is not used for a long time, it may be damp, rusty or aging. Therefore, when the hydraulic station is not used, the filter element should be stored in a dry and cool place to extend its service life.
6. Filter quality and selection
Choose high quality filter element: High quality filter element has better filtering effect and longer service life. When selecting filter elements, priority should be given to products with reliable quality, which are more economical in the long run despite the high initial investment.
7. System maintenance and monitoring
(1) Monitoring the working condition of the system: by regularly checking and monitoring the working condition of the hydraulic system, potential pollution problems can be found in time, and corresponding measures can be taken to reduce unnecessary loss of the filter element.
(2) Improve maintenance records: Establish maintenance records of hydraulic system and filter element, and adjust maintenance strategies and maintenance cycles according to the actual situation of the system.
