According to the filter material, it can be divided into paper filter, chemical fiber filter, metal mesh filter, metal powder sintered filter, PP filter, gap filter and activated carbon filter.
The hydraulic system is divided into: oil suction filter, pipeline filter and oil return filter.
The water filter element includes wire wound filter element, PP meltblown filter element, folding filter element, large flow filter element and activated carbon filter element.
I. Polypropylene filter element
PP filter element is also called PP meltblown filter element. Melt-blown filter element is made of polypropylene superfine fiber. The fibers of the filter element randomly form a three-dimensional microporous structure in space, and the pore diameters of the pores are distributed in a gradient along the filtrate flow direction, which integrates surface, deep layer and fine filtration, and can intercept impurities with different particle sizes.
Characteristics of PP cotton filter: the precision range of the filter is 0.5- 100μm, and its flux is more than 1.5 times that of the peak chamber filter with the same precision. It can be equipped with different types of end cover connectors to meet the needs of various engineering installations.
Second, the wire wound filter element
It is refined by accurately winding textile fiber yarns with good filtration performance on a porous frame. Its yarn materials include polypropylene fiber, acrylic fiber and absorbent cotton fiber. In the winding process, filter elements with different precision can be made by controlling the winding tightness and sparse density of yarn.
Features: It can effectively remove suspended solids and particulate impurities. It has a high purification effect on various liquids.
Third, fold the filter element.
Folding microporous filter core is a precision filter device made of polypropylene thermal spraying fiber membrane and nylon PTFE microporous filter membrane, which has the advantages of small volume, large filtering area and high precision.
Features: The filtering accuracy ranges from 0. 1μm to 60 μ m. The sealing of the filter element end cover and the connection of the whole structure are all through hot melt bonding. There are three types of filter element connectors: 222 connector, 226 connector and flat mouth. The products have been strictly and completely tested before leaving the factory to ensure the stable performance of the products.
Fourthly, activated carbon filter element.
There are two kinds of activated carbon filter products: compressed activated carbon filter and bulk activated carbon filter.
1. The compressed activated carbon filter element is made of coal-based activated carbon and coconut shell activated carbon with high adsorption value as filter materials and sintered and compressed with food-grade adhesive. The compressed activated carbon filter core is wrapped with a layer of non-woven fabric with filtering function inside and outside, which ensures that the carbon core itself will not lose carbon powder. Soft nitrile rubber gaskets are arranged at both ends of the carbon core, so that the carbon core can be put into the filter cartridge with good sealing performance.
2. Bulk activated carbon filter core puts the required activated carbon particles into a special plastic shell, and the end caps are welded on the two end faces of the shell by welding equipment, and non-woven fabric filters for filtering are respectively placed at both ends of the shell to ensure that carbon powder and black water will not fall off when in use. According to the needs of customers, the end cover of the shell can be made into different types of connection ports. Interface modes are: flat pressure type, pipeline type (models: 4042, 4044, 4046, etc. ).
Verb (abbreviation for verb) two-stage filter element
The last section: the precision of polypropylene melt-blown filter element is 5 μ m.
Next section: granular activated carbon filter element with built-in activated carbon 170g.
Material: ABS, PP
Length: 250 mm
Outside diameter: 70mm
Flux: 8L/S Total flux: 6-8T
Activated carbon index: strength >; 90; Iodine value (mg/g) > 950;
Six, resin filter
Resin is a porous and insoluble exchange material. There are millions of tiny plastic balls (beads) in the resin filter core of the water softener, and all the balls contain many negative charge exchange sites that absorb positive ions. When the resin is in a new state. These charge exchange sites are occupied by positively charged sodium ions. When calcium and magnesium pass through the resin storage tank, they contact the resin beads and displace sodium ions from the exchange position. Resin preferentially binds cations with strong charges, and the charges of calcium and magnesium ions are stronger than those of sodium ions. Then, that substitute sodium cation flows downward through the resin bed and out of the wat softener, so that the water softener send out "soft" water. Finally, all resin exchange positions are occupied by calcium and magnesium, so it is impossible to work any more.
Seven, stainless steel filter
Stainless steel filter point:
1, good filtration performance, and uniform surface filtration performance for filtration particle size of 2-200 μ m.
2. Good corrosion resistance, heat resistance, pressure resistance and wear resistance;
3. The filtering accuracy of stainless steel filtering holes is uniform and accurate;
4. The stainless steel filter element has large flow per unit area;
5, stainless steel filter is suitable for low temperature and high temperature environment; It can be reused without replacement after cleaning.
Application: Petrochemical, oil field pipeline filtration; Fuel filtration of refueling equipment and construction machinery and equipment; Equipment filtration in water treatment industry; Pharmaceutical and food processing fields;
The rated flow rate is 80-200l/min, the working pressure is 1.5-2.5pa, the filtration area (m2) is 0.01-0.20, and the filtration accuracy (micron) is 2-200μ m. The stainless steel woven net is used for pre-stage water removal of heavy oil combustion system and also for chemical liquid filtration, and the accuracy is/kl.
Eight, oil filter
Filter elements with different specifications and materials have accuracies ranging from 0.5 m to 80 m, which can meet the processing requirements of different mines and various oils.
Nine, hydraulic oil filter
The hydraulic oil filter element is mainly used to filter the oil in the hydraulic system, so as to remove the particles and rubber impurities in the hydraulic system and ensure the cleanliness of the hydraulic oil, so as to make the hydraulic system run normally.
