A kind of oil filter
Technical field
The present invention relates to oil filter technical field, more particularly to a kind of oil filter.
Background technology
The Main Function of engine motor oil be farthest reduce each part produced because of friction in the process of running it is miscellaneous
Matter, reduction energy loss and parts depreciation.Engine can produce the wearers such as substantial amounts of iron filings after working long hours, these mills
Damaging thing can enter in machine oil, it is therefore necessary to which recycling machine oil to this part carries out filtering treatment, so as to remove following after impurity
Ring is reused using machine oil.The machine oil that current automobile engine is used typically is filtered by cleaner, and its effect is
The metallic particles such as impurity, the especially iron filings such as dust, carbon precipitates and coal soot in removal machine oil, it is ensured that with clean machine
The kinematic pairs such as oil supply bent axle, connecting rod, camshaft, booster, piston ring, make machine oil play lubrication, cooling, cleaning action, from
And extend the life-span of these parts.So the performance of oil filter directly affects the performance and used life of engine, it is right
The normal operation of engine plays key effect.
The filter core of existing oil filter is usually a filter screen, when being filtered to machine oil, machine oil is passed into filter
In net, impurity is stayed in the bottom surface of filter screen, in filter process, the bottom surface of only filter screen is filtered to machine oil, filter area
Smaller, the bottom long term of filter screen, filter residue not easy-clear, easy blocking influences it normally to use.
