General Knowledge on “Hydraulic and Lubrication Duplex Oil Filters”

Hydraulic and Lubrication Duplex Oil Filters,also named Return Oil Filter, is mainly installed in the return pipe of the hydraulic system, all kinds of hydraulic components during operation produced grains and other contaminants can set the return line oil filter was blocked, to avoid further back to the tank, again pump sucked the return line oil filter permission pressure, depending on the pressure level in the range of 0.3 ~ 0.5MPa. Accuracy according to oil pollution requirements specifically identified.
Back to the oil filter the following factors to be considered to set some more, one important factor is the hydraulic shock, especially upstream cylinder and proportional valve, the cylinder under high pressure commutation and proportional valve suddenly out electricity, will have a huge impact instantaneous flow rate of the oil filter cartridge can cause great harm, have a full understanding in the design and selection when the return line oil filter, be strengthened in the structure.

Return Oil Filter has sub-fiber type, paper type, mesh and line-gap of four. Chemical fiber type than paper filter effect, high precision, chemical fiber type and paper type filter blockage cleaning more difficult, it is necessary to replace the filter. Back to the oil filter is equipped with pressure sender device, when the filter clogging due to pollution resulting oil inlet pressure of 0.35MPa, the switching signal will be issued, you should clean or replace the filter. The filter cartridge using the new synthetic filter material, with high filtration precision, through the oil capacity, the original pressure loss less, pollutant carrying capacity, etc., the filtration precision absolute filtration accuracy of calibration, the filter than p3,5,10,20 > 100, filtration efficiency n≥99%, in line with ISO standards.


1, metallurgy: for filtering rolling mill, continuous casting machine hydraulic system filters and a variety of lubrication equipment.
2, petrochemicals: refining, chemical production process of products and intermediate products separation and recycling, oil and gas injection wells in addition to the particulate filter.
3, textile: polyester melt filtration purification and even in the drawing process, the protection filter air compressor, compressed gas oil in addition to water.
4, electronic and pharmaceutical: reverse osmosis water, deionized water pretreatment filter, pre-treatment of the cleaning liquid and glucose filtration.
5, thermal power and nuclear power: gas turbines, boilers lubrication system, speed control system, bypass control system purification oil, feed pumps, fans and dedusting system purification.
6, machining equipment: filter paper machinery, mining machinery, injection molding machines and large-scale precision machinery lubrication systems and compressed air purification, tobacco processing equipment and spraying equipment.
