Our company is good at hydraulic filter element, so the focus of this article mainly shows the hydraulic filter element, today we will talk about the structure of hydraulic filter element.

Mesh filter element: mesh filter element is made by wrapping one or more layers of folded wire mesh on the porous framework. Mesh aperture is the precision of filter element, which is not easy to be damaged and can be cleaned and used repeatedly. However, due to low precision, it is generally used as oil absorption filter element.

Wire-gap filter element: copper or aluminum wires are wound on the porous framework according to a certain degree of tightness, and the oil is filtered through the seams. Due to the simple structure and large flux, this filter element is often filtered by oil return.

Paper filter element: it is divided into wood pulp paper filter element and glass fiber paper filter element.More sophisticated glass fiber paper filters are commonly used in industry,This kind of filter element has the advantages of high precision and good filtering effect. From the inside to the outside, the structure is in order: porous support framework, framework wrapping mesh, epoxy layer folding mesh (nylon folding mesh), polypropylene film protective layer, glass fiber main filtering, polypropylene film protective layer, epoxy layer folding mesh (nylon folding mesh), external porous support framework; The structure can be adjusted according to factors such as pressure and operating environment.

Sintered filter element: polymer or metal particle powder is used to melt and bond through high temperature surface, precision is particle gap, high strength, impact resistance, corrosion resistance, wide application range, but high cost.

Magnetic filter element: filter element with magnetic disc or bar, which is specially used to absorb iron impurities in oil, and is suitable for auxiliary filtration.
