Description
Technical field
The invention belongs to cleaner technical field, and specifically, the present invention relates to a kind of diesel fuel filter.
Background technology
Recent decades, diesel engine there occurs huge change, possess higher horsepower, higher fuel efficiency and
More preferable reliability.With the development of technology, engine is provided with greatly high-pressure common-rail fuel system (HPCR), and it requires to be up to
2000bar bigger pressure and tightened up tolerance.When organic or inorganic pollution, including water, impurity penetrates into fuel oil and supplied
To system, fuel oil part is easy for being damaged.And the critical component for preventing these potential dangers is exactly diesel fuel filter.
Diesel fuel filter can be divided into rough filter of diesel, diesel oil separator, diesel fine filter according to effect.Diesel oil coarse filtration
Device is generally seated in fuel tank as the term suggests major function is exactly impurity bigger in preliminary filtered fuel.Oil water separator
Major function is exactly to separate the water in diesel oil.The presence of water is very harmful for fuel system for diesel engine, corrosion, abrasion, stuck
The combustion process of diesel oil can even be deteriorated.And the diesel oil sulfur content in China is higher, easily react production in burning with water
Raw sulfuric acid corrodes engine component afterwards.Under state four standard, diesel fine filter is primarily used in filtered fuel 3-5 μm
Impurity, it is main filtration part.Oil water separator and fine filter are generally seated in outside fuel tank, are easy to observe, are maintained.But due to bavin
The filter efficiency of oil rectifier is higher, and its filter paper core requires stricter, and conventional based on composite, relatively advanced is
Nanometer materials, can keep more than 95% water-oil separating efficiency, and dust proof rate also will improve more than 3.5 times compared to common.
More advanced, core component of the filter core as cleaner is also required in structure, the fooled oil of filter core of existing diesel fuel filter is come in
Flowed directly to afterwards from Shang Gai on filter paper core, harmful substance also blocks filter paper core therewith flowing from top to bottom, causes element kit
After blocking, fuel oil runs out of and influences running car.
The content of the invention
The present invention provides a kind of diesel fuel filter, it is therefore an objective to avoids the impurity in fuel oil from being attached on filter paper core and cause to filter
Core assembly blocks.
To achieve these goals, the technical scheme taken of the present invention is：Diesel fuel filter, including shell body and be arranged at
Element kit inside shell body, in addition to be arranged between the shell body and the element kit and be used to that shell will to be entered
Internal fluid is guided to the flow-guiding structure on the internal face of shell body.
The flow-guiding structure, which has, to be used to guide fluid to the internal face of the shell body and to tilt the water conservancy diversion of extension
Face.
The flow-guiding structure is the flow guiding disc being sheathed on the element kit.
The flow guiding disc is cone.
The flow guiding disc has bigger diameter end and miner diameter end, and miner diameter end is connected with the element kit, and bigger diameter end is located at filter core
Between component and the shell body.
The element kit includes upper end cover, bottom end cover and the filter paper core being clipped between upper end cover and bottom end cover, described
Flow-guiding structure is connected between filter paper core and the shell body and with upper end cover.
The filter paper core is conical structure, and the bigger diameter end of filter paper core is connected with the upper end cover, the miner diameter end of filter paper core
It is connected with the bottom end cover.
The diameter of the upper end cover is more than the diameter of the bottom end cover.
The present invention diesel fuel filter, by outer enclosure interior set flow-guiding structure, by enter shell body diesel oil and
Impurity is oriented on shell body madial wall, makes diesel oil and impurity depend on gravity fall to flow to shell body bottom, so as to avoid firing
Impurity in oil is attached on filter paper core and causes element kit to block, and reduces the frequency of element kit replacing, extends bavin
The service life of oil rectifier.
