Description
Technical field
The present invention relates to a kind of fuel oil pump assembly, more particularly to a kind of it can adsorb the fuel oil pump assembly of iron content class impurity.
Background technology
Fuel system is an important component on vehicle chassis, and its function is to store and convey fuel oil.Fuel pump
Fuel oil is extracted from fuel tank, fuel oil is delivered to the fuel injector in engine bin by transfer pipeline, fuel injector will be in certain
Fuel oil under pressure state is ejected into combustion chamber and burnt.The clean level of fuel oil can very big influence fuel pump and other weeks
Some parts on side.
Impurity source in fuel oil is from two aspects, and one is derived from fuel oil in itself, because fuel oil transportation is mostly using gold
Belong to the transfer container of class, metal impurities may be mixed into due to reasons such as corrosion, another is the miscellaneous of presence in fuel tank itself
, there is the process of metal upper-lower casing welding in process of production in matter, especially irony fuel tank (compared to for plastic fuel tank),
There may be tiny welding slag bead.If the anti-corrosion measure inside irony fuel tank is not carried out, the coat of metal is caused to fall
Fall, peeling, corrosion etc. can all produce impurity.
Because fuel tank is a closed cavity, in whole life cycle, the impurity in fuel tank can not be excluded actively,
It can only be gathered in fuel oil, or be inhaled into fuel pump, entered in fuel delivery line.
The fine particle impurity of metal class can be brought for fuel pump after great destruction, long-play, can be caused
The abrasion of fuel pump body impeller, flow declines, and it is stuck to also result in impeller when serious, stall.Once feeding oil of fuel pump is asked
Topic, engine will be short of power until stalling, influences personal safety.
Primary filter is only devised in conventional fuel oil pump assembly structure, the aperture of filter screen of this kind of filter was not enough to
All impurity of filter, if aperture is too small, is easy to paste, if aperture is too big, does not have the effect of good filtering,
Specifically as shown in figure 1, fuel pump 1a is placed in oil storage barrel 2a, its underpart is provided with a filter 3a, and fuel oil is filtered
Enter fuel oil pump assembly afterwards.But this road filter 3a can not remove the fine impurity in fuel oil, a small amount of grit metal completely
Impurity still can enter fuel pump.
Existing improvement is all directed to filter screen in itself, not the cleaning for metal impurities or collection device.As announced
Number it is the A of CN 103511142, date of publication describes filter for 2014.01.15 patent, and its filter skeleton bendable is converted into L
Shape, by increasing the effective filtration area of oil filter, improves the oil suction area of fuel pump.Notification number is CN 103195625
B, the day for announcing describes the fuel-pump screen device of self-cleaning, including cylinder body, one end and cylinder body for 2014.12.10 patent
Middle part be fixedly connected side oil pipe, two be respectively fixedly connected with one end of cylinder body filter screen, in cylinder body and external diameter and cylinder
The sliding plug and two springs of the internal diameter matching of body, the side of the two ends of each spring respectively with a filter screen and sliding plug are connected.
During work, sliding plug is moved the impurity for making to be deposited on the outside of filter screen in cylinder body and come off.
Above-mentioned patent is all confined to improve filter screen in itself, or area increased, or makes to stick on filter screen
Impurity drops, and prevents filter screen from pasting.But all without reference to the impurity how handled in fuel oil (especially iron content class hard in itself
Grain) larger impurity is endangered for fuel pump.
