Basic introduction of string wound filter cartridge

String wound filter cartridge is a kind of deep filter element, used for low-viscosity, low-impurity filtration. It is made of textile fiber thread (polypropylene thread, absorbent cotton thread, etc.), which is precisely wound on a porous framework (polypropylene or stainless steel) according to a specific process. ) Made above. It has a honeycomb structure with sparse outside and dense inside, which can effectively remove suspended solids, particles, rust and other impurities in the fluid, and has very good filtering characteristics.

 

A good string wound filter cartridge can show the filtering effect of a depth-type filter material. The ideal condition is that it becomes denser from the outside to the inside. Therefore, when the string is wound, the density of the filter material must be controlled according to the thickness of the wire or with different string wound tension. Only with this kind of inner dense and outer sparse structure yarn around the filter element can have the depth effect of the depth filter material, which can effectively improve the filtration efficiency and intercept more contaminant particles. The filtration accuracy of the string wound filter cartridge material 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 denser the wire structure, the better the filtration The accuracy will be higher. However, in the filtering process, the filter material must be able to maintain its specific structure and pore size in order to provide stable and uniform filtering quality.
