Description
Technical field
The present invention relates to a kind of diesel oil oil water separators, especially with regard to a kind of diesel oil water-oil separating conducive to starting
Device.
Background technique
Important component of the diesel oil oil water separator as engine fuel oil system, major function is will be in fuel oil
Objectionable impurities and moisture etc. separated from fuel oil, make to enter each inside parts of engine fuel oil system and combustion chamber
Interior fuel oil more cleans, and to protect the normal work of engine, reduces abrasion, avoids blocking, improve discharge, raising is started
The machine service life.Diesel oil oil water separator with filter larger particles and separation water based on.
As shown in Figure 1A and 1B, diesel oil oil water separator is mainly made of filter seat A and element kit B, filter
It is connected through a screw thread between seat A and element kit B, the form of O-ring sealing is combined together.It is provided with out on filter seat A
Oil duct 1 and oil input channel 2, it is mutually indepedent between oil road 1 and oil input channel 2, it does not communicate directly mutually, element kit B is mainly by filter tank
Shell 3 and filter paper 4 form, and filter paper 4 is encapsulated in filter tank shell 3, and filter tank has been isolated into the dirty side 5 being connected with oil input channel 2
The clean side 6 being connected with oil road 1.Component part of the filter paper as diesel fuel filter filtering function most critical, tool
There is oleophilic drainage and the characteristic of particulate matter is isolated, i.e., fuel oil is very easy to through the filter paper in element kit, and particulate matter and water
Then most of dirty side for being isolated in filter core.
When newly changing filter core, the clean side of filter core is more empty；When the engine resting period is too long, the air in diesel oil is precipitated.?
When engine start, it is necessary to dragging engine for a long time fills the diesel oil of the clean side of filter core to top, that is,
Saying, the air of the clean side of filter core all must be discharged, and diesel oil could be gone out from oil water separator to oil pipe, until oil spout
Pump.To cause starting overlong time, or even difficult starting situation occurs.
If there is no check valve at the top of oil water separator, when engine is shut down, pipeline after diesel oil oil water separator
Fuel oil can be inhaled into the fuel oil of in oil water separator or even part diesel fuel filter under the suction function of oil water separator
Also it can be drawn into oil water separator, when engine being caused to be again started up, engine can not start or start time extension.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without
It should be considered as recognizing or implying in any form that the information constitutes existing skill already known to those of ordinary skill in the art
Art.
Summary of the invention
The purpose of the present invention is to provide a kind of diesel oil oil water separators conducive to starting, can effectively avoid starting
After machine is because shutting down, the fuel oil before oil transfer pump is inhaled into diesel oil oil water separator and leads to asking for engine difficulty starting
Topic.
To achieve the above object, the present invention provides a kind of diesel oil oil water separators conducive to starting, including filter

In a preferred embodiment, check valve is arranged to when the engine is running, suction of the check valve in oil transfer pump
It can be opened under power effect, so that the fuel oil in diesel oil oil water separator enters in oil transfer pump by check valve, and lead to
Cross the positive pressure side that oil transfer pump delivers fuel into fuel system.
In a preferred embodiment, check valve is also arranged to when engine is shut down, and oil transfer pump shuts down,
Oil transfer pump stops providing suction, while under the suction function of clean side, check valve is closed, oil transfer pump and oil water separator
Between fuel oil in pipeline will be stored in pipeline.
In a preferred embodiment, check valve is umbrella valve.
In a preferred embodiment, the root of diversion pipe is located at the position of filter core lower part 2/3~4/5.
Compared with prior art, the diesel oil oil water separator according to the present invention for being conducive to starting has the following beneficial effects:
1, by the way that one-way valve structures are arranged in the main oil gallery of diesel oil oil water separator oil road, it can effectively avoid and start
After machine is because shutting down, the fuel oil before oil transfer pump is inhaled into diesel oil oil water separator and leads to asking for engine difficulty starting
Topic；
2, by the way that diversion pipe is arranged inside diesel oil oil water separator main oil gallery to filter core, can effectively avoid engine because
The problem of after shutdown, large quantity of air is precipitated in diesel oil oil water separator, hinders engine quick start；
3, the root of diversion pipe is arranged in the position below of filter core lower part 2/3, to be conducive to engine quick start.
4, the present invention mode that increase check valve and diversion pipe combine in oil road is simple to operate, is easy to obtain
It takes, is easily achieved in the actual production process, batch easy to accomplish promotes and applies, and is provided with check valve and diversion pipe
Diesel oil oil water separator is remained exactly the same with existing diesel oil oil water separator contour structures, can be showed not changing engine
Engine difficulty startup separator is rectified and improved in the case where having any arrangement, is rectified and improved at low cost.Therefore, for because defeated after shutting down
Engine difficulty startup separator caused by the gather qi together of oil pump front end only needs to change one and provided by the present invention is provided with check valve
Engine difficulty startup separator can be effectively solved with the diesel oil oil water separator of diversion pipe, operation is very simple and convenient, can be significantly
It promotes engine failure and rectifies and improves efficiency.
