Replaceable filter materials used in the manufacture of hydraulic equipment are known in various designs. The support layer structure composed of warp and weft fabrics works in the form of filter materials. Today I will introduce the reasons for the obvious filtering effect of hydraulic filters.

The reason for the obvious filtering effect of hydraulic filter In order to be able to withstand the pressure difference and the dynamic flow dynamics of the filtrate during the filtration process, it is known that most of the support structures are made of metal fabrics, especially stainless steel wires, although this structure can prevent the alternating pressure during the operation of the filter Load, but the fluid permeability of the filter material should be reduced to obtain the advantage of high mechanical strength.

 

The corresponding support structure can be configured such that the open channel cross-section is defined by at least a part of the corresponding weft yarn, or in a continuous channel with two substantially parallel extending yarn sections, the cross-sectional shape extends to the full fold of the filter paper half folded height. 　　

At least a part of the corresponding weft yarn overlaps above or below each adjacent warp yarn pair, and together with the warp yarn pair, the hypotenuse of the right triangle cross section defining the air flow is parallel to the warp yarn.
