Description
Technical field
The present invention relates to a kind of fuel oil pump assembly, particularly relate to a kind of fuel oil pump assembly that can adsorb iron content class impurity.
Background technique
Oil-fired system is an important component part on car load chassis, and its function is to store and conveying fuel oil.Fuel pump extracts fuel oil from fuel tank, and by delivery line fuel oil is delivered to the oil sprayer in engine bin, the oil burning jet be under certain process stage is mapped to firing chamber and burns by oil sprayer.The clean level of fuel oil can affect very greatly some parts of fuel pump and other peripheries.
Impurity source in fuel oil is from two aspects, one is derive from fuel oil itself, because fuel oil transportation adopts the transfer container of metal species mostly, may due to reason pick-up metal impurity such as corrosion, another is the impurity that in fuel tank, itself exists,, there is the process of metal upper-lower casing welding in process of production, tiny welding slag bead may be there is in especially irony fuel tank (comparing plastic fuel tank).If the anti-corrosion measure of irony fuel tank inside is not carried out, cause the coat of metal to drop, peeling, corrosion etc., all can produce impurity.
Because fuel tank is an airtight cavity, in whole life cycle, the impurity in fuel tank cannot initiatively be got rid of, and can only gather, or be inhaled into fuel pump, enter in fuel delivery line in fuel oil.
The fine particle impurity of metal species can bring great destruction for fuel pump, after long-play, can cause the wearing and tearing of fuel pump body impeller, and flow declines, and impeller also can be caused stuck, stall time serious.Once feeding oil of fuel pump has problem, motor just can be short of power until stall, affects personal safety.
Conventional fuel oil pump assembly structure only devises primary filter, the aperture of filter screen of this kind of filter is not enough to filter all impurity, if aperture is too small, then be easy to stick with paste, if aperture is too large, then do not have the effect of good filtration, specifically as shown in Figure 1, fuel pump 1a is placed in oil-storing barrel 2a, and its underpart is provided with a filter 3a, enters fuel oil pump assembly after being filtered by fuel oil.But this road filter 3a can not remove the fine impurity in fuel oil completely, and a small amount of grit metal impurities still can enter fuel pump.
Existing improvement is all directed to filter screen itself, not for the clean of metal impurities or gathering-device.If publication No. is CN103511142A, date of publication be 2014.01.15 patent describes filter, its filter skeleton bendable is converted into L shape, by increasing the effective filtration area of oil purifier, improves the oil suction area of fuel pump.Notification number is CN103195625B, the day for announcing is the fuel-pump screen device that patent describes self-cleaning of 2014.12.10, comprise cylinder body, side oil pipe that one end is fixedly connected with the middle part of cylinder body, two each be fixedly connected with one end of cylinder body filter screen, be positioned at cylinder body and sliding of mating with the internal diameter of cylinder body of external diameter is filled in and two springs, the side that the two ends of each spring are filled in a filter screen and cunning is respectively connected.During work, the motion in cylinder body of sliding plug makes the impurity be deposited in outside filter screen come off.
Above-mentioned patent is all confined to improve filter screen itself, or area increased, or the impurity sticked on filter screen is dropped, and prevents filter screen from sticking with paste.But all do not relate to the impurity itself (especially iron content class hard particles) how processed in fuel oil and larger impurity is endangered for fuel pump.
Summary of the invention
