Abstract
The invention discloses an oil filter element. The oil filter element comprises a folding filtering material, a connector and a flat head, wherein the connector and the flat head are arranged at the two axial ends of the folding filtering material correspondingly. The outer side of the folding filtering material is provided with a nylon net sleeve used for fixing the filtering material, and the two axial ends of the nylon net sleeve are fixedly connected to the connector and the flat head correspondingly. Due to the fact that the nylon net sleeve is fixedly connected with the connector and the flat head, the nylon net sleeve can be reliably fixed to the outer side of the folding filtering material, the nylon net sleeve cannot be disengaged relative to the folding filtering material, the folding filtering material can still keep a stable structure even when the folding filtering material is subjected to back wash pressure, the folding filtering material can be effectively prevented from deforming, and the folding filtering material can be reliably fixed. In the production process of the oil filter element, the pre-folded filtering material is directly sleeved with the nylon net sleeve, so that the production efficiency is greatly improved, and the cost is better reduced. The invention further discloses a hydraulic system comprising the oil filter element, the folding filtering material in the oil filter element can be more reliably fixed, and meanwhile the cost is relatively low.
