The filtration method and mechanism of the wire-wound filter cartridge have a unique way. The liquid to be filtered flows from the outside to the inside. After being filtered by the yarn filter cartridge, the impurities in the liquid will be retained due to the structure of the wire-wound filter element. This structure is a deep void gradient, which enables large particles to be retained on the outer layer and small particles on the inner layer. This filtration mechanism not only removes the filter residue but also has a very high dirt-holding capacity, effectively filtering out impurities.
The filtration mechanism of the pp string wound filter element is mainly determined by its unique construction. Let's take a detailed look at this structure.
The support of the pp string wound filter cartridge is mainly composed of two types of skeletons, one is the polypropylene skeleton (PP skeleton), and the other is the stainless steel skeleton. These two skeletons are selected for use according to different working environments. After determining the skeleton, textile fibers are wound around the surface of the skeleton. The textile fibers commonly used for winding mainly include three types: polypropylene thread, degreased cotton thread, or glass fiber yarn. Through a unique winding method, a deep honeycomb structure is formed, which is in the form of dense inside and loose outside.
As for the filtration accuracy of the polypropylene string wound filter cartridge, the determination of the accuracy is also relatively intuitive. It mainly affects the accuracy by controlling the tightness of the wound textile fibers. Generally, the filtration accuracy range of the wound filter element is from 1 to 100 microns.
