Wire-wound filter is a kind of deep-layer filter. It is used for low-viscosity and low-impurity filtering. It is made of textile fiber thread (polypropylene thread, absorbent cotton thread, etc.), which is precisely wound around a porous framework (polypropylene or stainless steel) according to a specific process. Made of the above, it has a honeycomb structure with dense outer and inner layers, which can effectively remove suspended solids, particles, rust and other debris in the fluid, and has very good filtering characteristics.
A well-wound wire-wound filter element can show the filtering effect of a depth-type filter material. The ideal condition is that it is denser from the outside to the inside. Therefore, when winding, the thickness of the wire or different winding tension must be used. To control the density of the filter material, a wound filter element with such an inner dense and outer sparse structure can have the depth effect of the depth type filter material, effectively improve the filtering efficiency, and intercept more dirt particles. The filtering accuracy of the wound filter is determined by the thickness of the wire and the density of the winding. The thinner the wire, the closer it can be, the smaller the pores and the higher the accuracy; the same, the denser the wire structure The higher the filtering accuracy. However, in the process of filtering, the filter must also maintain its specific structure and pore size in order to provide stable and uniform filtering quality.
