keyword description: how to distinguish the pros and cons of filter quality

assess the quality of filter, mainly from the following several aspects: the selection of the filter material; The structure of the filter element; The production process; Product testing; Appearance quality, etc. Filter material with metal mesh, metal mat, glass fiber, plant fiber, soft magnetic materials, etc. Metal mesh by metal filament woven, square mesh and twill breakdown, small flow resistance, it use. Can be used in high temperature range. Mainly used for coarse filtration system, filter it belongs to the surface, can use repeatedly washing. Oil suction filter generally choose 60 300便士。 M metal mesh filter material, lubricating system sometimes use 25200 p. M metal mesh. Now there are 520 p. M metal mesh filter material used for special occasions. Metal mat is made of metal fiber felt, has the performance of glass fiber, is a deep filter. It has a labyrinth three-dimensional structure, loose degree is high, small flow resistance. Pollutant carrying capacity is strong, long service life, can be used in large temperature range. A range of 5 - is accuracy 20便士。 m。 Because it is expensive, only in high temperature filtration medium or special requirements, can be cleaned ( To clean with ultrasonic cleaning machine) And repeated use. Glass fiber is now one of the most common and the best performance of the filter material, it is widely used in hydraulic system, belongs to jump filter, precision range is 1 - 30 is swollen, and affected by the work environment changes little, small flow resistance, pollutant carrying capacity is strong, the differential pressure in excess of the prescribed range is still has a high ability to filter out fine particles. Chemical resistance is good, but do not apply to water glycol mixture. Organic chemical fiber is a kind of very good filter material, its accuracy range is 3 - 30 p。 M, is a deep filter, can tolerate high differential pressure, small flow resistance, large amount of sludge. Strong chemical tolerance, especially suitable for the liquid emulsion and synthetic ah. Tear resistance, but the precision is slightly changes with the temperature change. Plant fiber is the first to use fiber filter material, due to uneven distribution of it away L size, cannot use absolute accuracy to express, only nominal expression filtration precision, precision filtration efficiency is low, but due to the low cost, wide temperature scope is glass fiber, so it is widely used in the engine lubrication, diesel oil, petrol filter and air filter, the name of the general accuracy range is 10100 p. m。 Fiber thickness influence the precision of the filter material and capacity. The fiber fine precision higher; The smaller the porosity, the more the differential delta p; Between the fibre and fibre to resin adhesive. Adhesive uniform filter material has the high ability to resist damage, fluctuations in pressure, and flow rate, temperature, aging under these factors not make the fiber damage loss, cause particles through the filter material, pollution caused by system. Fiber 墯 sex should be used, no chemical reaction, do not produce inflation, not limited by storage period. Now is the most used composite fiber in the world, it is usually 3 - 5 layer, middle filter layer is short fibers, internal and external protection layer for long fiber. Guangzhou filter source water filter equipment co. , LTD. Is China's first development and production of water filter various types of products are: PP wire wound filter, PP folded filter, PP melt-blown filter, activated carbon filter, resin filter, big flow filter, and provide the matching equipment professional factories, was also the first three development line around the filter, and participate in the formulation of the chemical wire wound type filter core ( Water filter) One of the industry standard drafting unit. Sincerely look forward to cooperation with you! 。
