The core materials of hydraulic oil filter elements are primarily divided into the filtration layer and the support-protective layer. The characteristics and applicable scenarios of different materials vary significantly. Choosing the right material is key to ensuring the reliable operation of the hydraulic system.
In addition to the filtration medium, other parts of the filter element are equally critical:
End Caps and Skeleton: Typically made of metal (such as steel or aluminum) or engineering plastics, they primarily provide support and protection for the internal filter material, withstand pressure, and ensure sealing.
Seals: Commonly made of materials such as nitrile rubber or fluororubber, they are used to ensure a tight connection between the filter element and the filter housing, preventing oil leakage.
In summary, wire mesh (particularly stainless steel) filter elements are known for their high strength, high-temperature resistance, and reusability, making them suitable for demanding conditions and applications where durability is prioritized. On the other hand, filter elements made of materials such as glass fiber are distinguished by their high filtration precision and large dirt-holding capacity, making them a crucial choice for ensuring oil cleanliness.
