Description
Technical field
The present invention relates to technical field of engines more particularly to a kind of dusty, diesel quality difference environment in use
Diesel engine fuel-firing pre-filtrating equipment.
Technical background
The most very severe of environment that movable screw air compressor uses, due to working environment, badly there is secondary pollutions
(including oil tank, oil drum, oil gun, the pollution of oil pipe, the environmental pollution of construction site).Therefore the fuel oil being had by oneself in diesel engine
It installs grade one filter in system additional, but does not reach good effect, grade one filter can only filter a part of impurity, and water
Divide the very little of filtering, some moisture can also lead to not work normally into fuel system.In fuel tank according to the humidity of environment not
Together, the water accumulating volume of generation is also different, and the effect of filtering moisture content is only unable to reach by the filtration system that mechanical equipment is had by oneself.Root
According to residing environment, there are different humidity.After work is parked, different degrees of ponding and impurity can be generated in fuel tank, and
Original fuel oil filter cannot fully meet the demand and standard of filtering.In addition fuel oil (diesel oil) oil product difference in all parts of the country
Property is very big, and the service life for the fuel oil filter that engine carries is greatly reduced, and causes compressor and starts in different areas
The maintaining of machine and maintenance time greatly shorten.Relatively better in environment, the good area of oil product, the maintenance of engine is protected
The foster period in contrast may be longer；But for bad environments, the area of oil product difference, the maintaining of engine
Period will greatly shorten many.In order to effectively extend the maintenance cycle of engine, then compressor is installed additional in oil inlet pipeline section
Fuel oil pre-filtering device.
Invention content
It is an object of the invention to overcome the defect of the prior art, a kind of matter that can be improved into engine fuel is provided
Amount extends the fuel oil pre-filtering device of the service life of engine.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of diesel engine fuel-firing pre-filtrating equipment, between engine and the pipeline of fuel tank, including filtering
Cylinder is equipped with head cover at the top of filtration barrel body, and bottom is connected with the top of water-oil separating seat；It is set inside the filtration barrel body
It is equipped with filter core；Filtration channel is provided between the water-oil separating seat and filtration barrel body；The lower part of the water-oil separating seat
Grease cyclone separator is set；The water-oil separating seat both sides are respectively equipped with fuel inlet and fuel outlet；The grease cyclone separator
Lower part transparent filter bowl is installed.
Preferably, the cup body of the transparent filter bowl is equipped with graduation mark and scale value.
Preferably, the bottom of the transparent filter bowl cup body is equipped with drainage jam.
Preferably, the precision of the filter core is 10 μm.
Preferably, head cover tie down screw is provided on the head cover.
Preferably, the filtration barrel body inner diameter is 100mm.
Preferably, the opening diameter of the fuel inlet is 20mm.
The present invention has the advantages that compared with prior art：
1st, the present invention is between engine and the pipeline of fuel tank by setting fuel oil pre-filtering device, when fuel oil is certain
Flow velocity passes through the import of diesel engine fuel-firing pre-filtrating equipment, enters the filter core inside filtration barrel body, in fuel oil
95% impurity is filtered.
2nd, water-oil separating seat can be again passed by by the fuel oil of filter core, fuel oil passes through special whirling passage, from
Under the action of mental and physical efforts, the water in fuel oil can flow to bottom by getting rid of to inner wall, and the oil after being detached then is flowed out by outlet, and process is secondary
After filtering, wherein about 99.7% oil can be separated, and droplet diameter at this time is mostly below 1 μm.
3rd, the present invention is after diesel engine fuel-firing pre-filtrating equipment has been installed additional, into the dust impurities of engine and water meeting
It substantially reduces, greatly improves the service life of engine in harsh environment, while also largely reduce and start
Machine maintaining cost.
4th, it after using above-mentioned fuel oil pre-filtering device, is expected to the system filtering core device replacement cycle of diesel engine extending 2
~3 times.

Specific embodiment
In order to make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, implement below in conjunction with the present invention
Technical solution in example carries out clear, complete description, it is clear that and described embodiment is the section Example of the present invention, and
It is not all of embodiment.Based on the embodiment of the present invention, those of ordinary skill in the art are not before making the creative labor
All other embodiments obtained are put, belong to protection scope of the present invention.
As shown in Figure 1, a kind of diesel engine fuel-firing pre-filtrating equipment, mounted on the pipeline of engine and fuel tank it
Between, including filtration barrel body 1, preferably 1 inner diameter of filtration barrel body is 100mm in the present embodiment, and filtration barrel body 1 was internally provided with
Filter core 4 is filtered, the top of filtration barrel body 1 is equipped with head cover 2, head cover tie down screw 3 is provided on head cover 2, passes through head cover locking screw
Bar 3 very easily replaces the filter core 4 that 1 internal organ of filtration barrel body block up.The bottom of the filtration barrel body 1 and water-oil separating seat 5
Top is connected, and filtration channel 11 is provided between the water-oil separating seat 5 and filtration barrel body 1, can be with by filtration channel 11
The fuel oil filtered on filter core 4 is made to enter 5 lower part of water-oil separating seat setting grease cyclone separator 6 and carries out mistake again
Filter.The fuel inlet 9 and fuel outlet 10 are separately positioned on the both sides of water-oil separating seat 5.The lower part of the grease cyclone separator 6
Transparent filter bowl 7 is installed, after secondary filter, the moisture in fuel oil can be deposited on the bottom of transparent filter bowl 7.The present embodiment
In, be equipped with graduation mark and scale value on the cup body of transparent filter bowl 7, the moisture that knowing of can will be apparent that filters out number, together
When the bottom of transparent filter bowl 7 be equipped with drainage jam 8, the moisture in transparent filter bowl 7 can be discharged at any time.
The present invention operation principle be：Fuel oil enters the fuel oil of diesel engine fuel-firing pre-filtrating equipment with certain flow velocity
Import 1, the filter core 4 being first into inside filtration barrel body 1, the precision of filter core 4 described in the present embodiment is 10 μm,
95% impurity is filtered in fuel oil after the filtering of filter core 4.At this moment, the fuel oil after first time filtering has been carried out
The grease of 5 lower part of water-oil separating seat setting is entered by the filtration channel 11 set between water-oil separating seat 5 and filtration barrel body 1
Filtered again in cyclone separator 6, since the proportion of fuel oil and water is different, in this way, fuel oil passes through special whirling passage, from
Under the action of mental and physical efforts, the water in fuel oil can flow to bottom by getting rid of to the inner wall of transparent filter bowl 7, and the oil after being detached then is gone out by fuel oil
Mouth 10 flows out, wherein about 99.7% oil can be separated, and droplet diameter at this time is mostly below 1 μm.
After the present invention is by installing diesel engine fuel-firing pre-filtrating equipment additional, dust impurities and water into engine can be big
It is big to reduce, the service life of engine in harsh environment is greatly improved, while also largely reduce engine
Maintaining cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
