Abstract
The invention belongs to the technical field of filter devices, and relates to a fuel and water separator assembly, in particular to a fuel filter assembly for fuel and water separation. The fuel filter assembly comprises a filter element and a filter base. A filter channel is arranged on the upper middle portion of the filter element, and a water drainage channel is arranged on the lower middle portion of the filter element. The fuel filter assembly is characterized in that a double-end hollow bolt is arranged in the filter base, and the filter element and the filter base are in threaded connection through the double-end hollow bolt; fuel passing holes are formed in the middle portion of the double-end hollow bolt and communicate with a fuel inlet valve arranged on the filter base; the top of the double-end hollow bolt communicates with fuel outlet holes formed in the filter base; a fuel outlet valve is further arranged on a channel of the fuel inlet valve and the fuel outlet holes; and a manual pump is arranged on one side of the filter base and used for locating and controlling work of the fuel inlet valve and the fuel outlet valve. Under the abnormal work condition that fuel cannot be fed into an engine, the manual pump is adopted for fuel feeding, and the fuel is filtered through the filter element, so that the situation that water and particle impurities directly enter the engine, and consequently work of the engine is seriously influenced is avoided; and the injection amount and injection precision control of the high pressure common rail fuel can be improved, the service life of a fuel nozzle is prolonged, maintenance is convenient and fast, and the use flexibility is improved.
Description
Technical field
The present invention relates to a kind of defecator, be specifically related to the fuel filter assembly of a kind of oil-water separation.
Background technology
The world today, one of motor vehicle exhaust emission source becoming atmospheric pollution, it is subject to countries in the world consumer and more and more pays close attention to.In order to reduce motor vehicle exhaust emission pollution on the environment, it has all been carried out necessary guiding and constraint by various countries in policy, wherein the oxynitride of exhaust emissions is done strict regulation, in order to reach qualified discharge standard, electromotor manufacturer has done every improvement technically, and high-pressure common rail technology is exactly main technological means.Fuel injection amount and injecting time are required for accurate control by high-pressure common rail, in engine work situation, fuel oil all has to filter through oil-water separation and decontamination and re-uses, but occur running out of under oily fault at electromotor, prior art is all often by other oil circuit directly by fuel delivery electromotor, namely the fuel oil supplied be all without filter and oil-water separation, in fuel oil per se with particulate contaminant will enter electromotor, accelerated wear test hole in nozzle；Atomizer is produced corrosion and also has a strong impact on electromotor work by the sub-granule of large quantity of moisture contained in fuel oil, can not meet high-pressure common rail and fuel injection amount and injecting time are required for the requirement of accurately control, and the manual pump of existing product is all rivet on filter block, in case of emergency also cannot detachable maintaining.
Summary of the invention
For problems of the prior art, it is an object of the invention to design provides a kind of fuel filter assembly with oil-water separation.
A kind of fuel filter assembly of oil-water separation, including filter element, filter block, filter element middle and upper part is provided with filtration channel, filter element middle and lower part is provided with the passage that discharges water, it is characterized in that in filter block, arranging double-head hollow bolt, filter element is connected by double-head hollow bolt thread with filter block, it is provided with oil through in the middle part of double-head hollow bolt, described oil through is connected with the inlet valve arranged on filter block, double-head hollow bolt top is connected with the oil outlet arranged on filter block, the inlet valve passage with oil outlet is additionally provided with delivery valve, filter block side arranges manual pump for positioning and controlling inlet valve, delivery valve works.
The fuel filter assembly of described oil-water separation, it is characterised in that oil outlet is arranged below preventing reverse flow valve.
The fuel filter assembly of described oil-water separation, it is characterised in that manual pump and filter block are dismountable structure, and connect by screw is fixing.
The fuel filter assembly of described oil-water separation, it is characterised in that steel screw thread air vent is set on filter block.
The fuel filter assembly of described oil-water separation, it is characterised in that the passage that discharges water arranges level sensor.
The fuel filter assembly of described oil-water separation, it is characterised in that oil through is ring-shaped.
Present configuration is novel, reasonable in design, run out of in the non-normal working situation of oil at electromotor, adopt manual pump fuel feeding, and by this fuel oil through filter element filtering, it is prevented that moisture, particulate contaminant are directly entered electromotor, and have a strong impact on electromotor work, improve high-pressure common rail fuel injection amount and injection accurately controls, increasing the service life of fuel injection nozzle, it is convenient to keep in repair, and improves the flexibility ratio used.

Detailed description of the invention
The present invention is further illustrated below in conjunction with Figure of description.
A kind of fuel filter assembly of oil-water separation, including filter element 2, filter block 6, filter element 2 middle and upper part is provided with filtration channel, filter element 2 middle and lower part is provided with the passage that discharges water, double-head hollow bolt 3 is set in filter block 6, filter element 2 is threadeded by double-head hollow bolt 3 with filter block 6, annular oil through 4 it is provided with in the middle part of double-head hollow bolt 3, described oil through 4 is connected with the inlet valve 7 arranged on filter block 6, double-head hollow bolt 3 top is connected with the oil outlet 5 arranged on filter block 6, the passage of inlet valve 10 and oil outlet 5 is additionally provided with delivery valve 8, filter block 6 side arranges manual pump 9 for positioning and controlling inlet valve 10, delivery valve 8 works.
When engine work, inlet valve 10, delivery valve 8 are all closed modes, and fuel oil enters filter element 2 from oil-in 13, through filtration and the oil-water separation of filtration core 2, removing particulate contaminant and moisture, fuel oil directly gives engine oil through oil outlet 5 from double-head hollow bolt 3.When electromotor non-normal working, when namely running out of fuel oil, manual pump 9 can only be pressed and carry out manual pump oil work, now, often press with hands, suction by manual pump 9, inlet valve 10 and delivery valve 8 will be opened, fuel oil also just filters through filter element 2, flow to filtration channel to double-head hollow bolt 3 and suck inlet valve 10, then flow out from delivery valve 8, then achieve the goal to engine oil through oil outlet 5, namely adopt above-mentioned structure, ensure under abnormal condition confession oil with under normal condition the oily quality of confession be the same.It is arranged below preventing reverse flow valve 7 at oil outlet 5, blows back into double-head hollow bolt 3 or filter element 2 and can not fully be used through filtering clean oil product to not allow after manual pump oil.Manual pump 9 and filter block 6 are in dismountable structure, and connect by screw 11 is fixing, are provided with the seal gasket preventing leakage of oil in manual pump 9, in time there is a need to keep in repair, it is possible to turn on screw 11, be repeatable utilization compared with rivetting, and very convenient.Arranging steel screw thread air vent 12 on filter block 6, the hardness of steel is high, because fuel filter is also required to frequent venting, the relative aluminum of steel, hardness is more reliable, is not likely to produce aluminum bits and falls into oil duct and destroy engine work；The passage that discharges water arranges level sensor 1, namely when water level accumulation is too much, with regard to automatic alarm, sluices.
