How To Extend The Service Life Of Hydraulic Oil Filter Element?
The key to extending the service life of hydraulic oil filters lies in regularly replacing and maintaining the cleanliness of the hydraulic system.
Regularly replace the filter element: Depending on the usage of the equipment and the degree of contamination of the hydraulic oil, regularly replacing the filter element is the key to extending its lifespan. It is generally recommended to replace the filter element every quarter or every 500 hours to avoid filter blockage that may cause the hydraulic system to malfunction
2. Maintain the cleanliness of the hydraulic system: The cleanliness of the hydraulic system directly affects the lifespan of the filter element. High pollution intrusion rate will increase the burden on the filter element and shorten its service life. Therefore, it is crucial to strictly limit environmental pollution entering hydraulic systems
3. Precautions for replacing hydraulic oil: When replacing the hydraulic oil filter element, it is necessary to first drain the existing hydraulic oil in the box and check whether the return oil filter element, suction filter element, and pilot filter element have iron filings, copper filings, or other impurities. If these impurities are found, they need to be inspected and the system cleaned before replacement. At the same time, hydraulic oil of different grades and brands cannot be mixed, otherwise it may cause the hydraulic oil filter element to react and deteriorate, producing flocculent substances
5. Precautions for installing a new filter element: Before adding new hydraulic oil, it is necessary to install the hydraulic oil filter element, especially the suction filter element, because its pipe mouth is directly connected to the main pump. If impurities are accidentally allowed to enter, it may accelerate the wear and even damage the main pump. After adding new hydraulic oil, it is important to ensure that the main pump has been purged of air, otherwise it may cause problems such as no movement of the entire vehicle and abnormal noise from the main pump
6. Other maintenance measures: When replacing the hydraulic oil filter element, pay attention to flushing the system oil tank and pipelines clean, and add oil through a refueling device with a filter. Preventing direct contact between the oil in the fuel tank and the air, and avoiding mixing old and new oil, can help extend the service life of the filter element
