Oil fluid filter with magnetic adsorption mechanism

Abstract

The invention discloses an oil fluid filter with a magnetic adsorption mechanism. The oil fluid filter comprises a shell, a filter cartridge and a magnetic adsorption mechanism, wherein the outer part of the shell is wrapped by the magnetic adsorption mechanism; the magnetic adsorption mechanism sequentially comprises a first magnetic shielding sleeve, a magnet and lifting mechanisms from inside to outside; and the outer part of the magnet is wrapped by a second magnetic shielding sleeve. Due to the matching of all the parts, influences of the magnetic field of the magnet to other surrounding equipment can be avoided while iron wear debris in an oil fluid can be efficiently eliminated, and the aims of backflushing the filter cartridge and ensuring the filtering effect of the filter cartridge can also be achieved while the iron wear debris adsorbed on the shell can be automatically eliminated.

Description

Technical field [0001] The invention relates to the field of filters, in particular to an oil filter provided with a magnetic adsorption mechanism. Background technique [0002] There will be friction in the moving parts of the car engine when it is working, and the friction will produce small iron wear debris and mix into the oil. At present, the paper filter element commonly used in oil filters can only filter out 60% of the impurities in the oil. , And 40% of impurities cannot be effectively filtered out. Among these 40%, iron wear debris accounts for a high proportion, because the iron wear debris particles are relatively small, and the iron wear debris that cannot be filtered is circulated with the oil. Other parts bring wear and tear, so that over time, wear will change the original design parameters of the engine, increase engine noise, increase fuel consumption, and reduce power, while shortening the service life of the engine and the oil life cycle. [0003] In addition, ...

AI Technical Summary

Problems solved by technology

[0002] When the car engine is working, there will be friction in the moving parts, and the friction will produce fine iron debris and be mixed into the oil. However, the paper filter element commonly used in the oil filter can only filter out 60% of the impurities in the oil. , there are still 40% of impurities that cannot be effectively filtered out. In this 40%, the iron wear debris accounts for a relatively high proportion, because the iron wear debris particles are relatively small, and the iron wear debris that cannot be filtered out will be released with the oil circulation. Other parts bring wear and tear. If this goes on for a long time, the wear will change the original design parameters of the engine, increase engine noise, increase fuel consumption, and reduce power. At the same time, it will shorten the service life of the engine and the service life of the oil.

[0003] In addition, in the existing fuel oil, many ferromagnetic impurities are also mixed in the fuel due to the multiple conversions of pipelines and containers during transportation. Ferromagnetic impurities can accelerate the wear and blockage of fuel pumps and fuel injectors, resulting in poor fuel injection quality. Decrease, poor atomization, unclean combustion, reduced power, increased fuel consumption, increased noise, damage to engine components such as valve trains, cylinder liners, piston rings, etc. If ferromagnetic impurities cannot be well filtered out of fuel, Also damages the engine
