‌How to determine the parameters of hydraulic oil filter element

Contaminant types‌
Select filter elements with different pore sizes and materials according to the possible contaminants in the filtered oil (such as sludge, sand, iron filings, water, etc.). For example, iron filings require high-precision filter elements, while water requires water-absorbing filter elements.

‌Working pressure‌
The working pressure of the hydraulic system directly affects the selection of filter elements. Under high pressure, the filter element may deform or break, so it is recommended to use plate or mesh filter elements to ensure its strength and stability.

‌Flow rate‌
The flow rate determines the filter element's passing capacity and service life. Selecting a filter element with too small a flow rate will result in insufficient oil flow and increase pressure loss; while a filter element with too large a flow rate may not be able to effectively filter impurities.

‌Accuracy‌
The accuracy of the filter element should be determined according to the sensitivity and accuracy requirements of the components in the hydraulic system. Generally speaking, the accuracy of the filter element should be higher than the accuracy of the system components to ensure the cleanliness of the oil. For example, high-precision filter elements are suitable for precision hydraulic equipment.

‌Filter element material‌
The material of the filter element (such as paper, metal mesh, fiber, etc.) affects its filtering effect and durability. For example, paper filter elements have high precision but are easily contaminated, while metal mesh filter elements are durable but have low precision. The appropriate material should be selected according to actual needs and oil characteristics.

‌Summary‌
To determine the model parameters of hydraulic oil filter elements, it is necessary to comprehensively consider factors such as pollutant type, working pressure, flow rate, precision, material, etc. The correct selection of filter elements can not only improve the operating efficiency of the hydraulic system, but also extend the service life of the equipment. It is recommended to select the filter element according to the specific system requirements and the above methods.
