Product Details

31070-190203 filter element

Resin is a porous, non replaceable material. The resin filter in the water softener contains millions of fine plastic balls (beads), all of which contain many negative charge exchange sites that absorb positive ions. When the resin is in a new state? These charge exchange positions are occupied by positively charged sodium ions. When calcium and magnesium pass through the resin storage tank, they come into contact with resin beads and replace sodium ions at the exchange site. Resin preferentially binds cations with strong charges, with calcium and magnesium ions having stronger charges than sodium ions. Replace sodium cations and then flow downwards through the resin bed and out of the water softener, so that the water softener sends out "soft" water. All resin exchange positions are occupied by calcium and magnesium, and can no longer work.

Filter cartridges are divided into air filter cartridges, water filter cartridges, and oil filter cartridges according to the medium of use.

According to the material of the filter element, it can be divided into paper filter element, synthetic fiber filter element, metal mesh filter element, metal powder sintered filter element, PP filter element, wire gap filter element, activated carbon filter element, etc.

The hydraulic system is divided into: oil suction filter element, pipeline filter element, and return oil filter element.

The water filter element includes wire wound filter element, PP melt blown filter element, folding filter element, high flow filter element, and activated carbon filter element.

1、 PP filter cartridge

PP filter cartridge, also known as PP melt blown filter cartridge, is made by hot-melt entanglement of polypropylene ultrafine fibers. The filter fibers randomly form a three-dimensional microporous structure in space, and the pore size is distributed in a gradient along the flow direction of the filtrate. It integrates surface, deep, and fine filtration, and can intercept impurities of different particle sizes.

Characteristics of PP cotton filter element: The precision range of the filter element is 0.5-100 μ m, and its flux is more than 1.5 times that of the peak room filter element with the same precision. Different types of end cap joints can be configured to meet the needs of various engineering installations.

2、 Wire wound filter element

It is refined by precisely winding textile fiber yarn with good filtering performance onto a porous skeleton. The yarn materials include polypropylene fiber, acrylic fiber, defatted cotton fiber, etc. By controlling the tightness and density of the yarn during winding, filter cartridges of different accuracies can be made.
