Abstract
The utility model discloses a fuel oil pump assembly with two-level filtration. The fuel oil pump assembly with the two-level filtration comprises a fuel oil pump and filter screens. The fuel oil pump assembly with the two-level filtration is characterized in that the fuel oil pump is arranged in an oil storage barrel and is provided with an oil inlet, a main oil outlet and a branch oil outlet, the filter screens comprise a primary rough filter screen and a secondary refined filter screen, the primary rough filter screen is placed outside the oil storage barrel and is connected with a jet device, the jet device is placed in the oil storage barrel, a jet flow inlet of the jet device is connected with the branch oil outlet, and the secondary refined filter screen is placed in the oil storage barrel and is connected with the oil inlet. The fuel oil pump assembly with the two-level filtration has the advantages that defects that the fuel oil pump is stuck and the service life of the filter screens is short caused by insufficient cleanliness of fuel oil are overcome effectively, the oil storage function of the oil storage barrel enables the fuel oil pump to be dipped in the fuel oil for uttermost heat dissipation in a low oil level state of an oil box, and stability of oil supplying is guaranteed in the low oil level state of the oil box due to the fact that the oil inlet of the fuel oil pump is not separated from the fuel oil even when a car is running on a bumpy road.
Description
Technical field
The utility model relates to a kind of fuel oil pump assembly of in the automobile oil supply system, using.
Background technique
The effect of fuel oil pump assembly is to be stored in fuel delivery in the fuel tank to the fuel pipe of oil sprayer, supplies with the fuel oil of oil sprayer certain pressure, and oil sprayer drives motor car engine and carries out work according to the instruction oil spout of ECU.Traditional fuel oil pump assembly, its fuel pump directly places in the fuel tank during work, and the filler opening of fuel pump is connected with filter screen one.Traditional fuel oil pump assembly, have the following disadvantages: 1. because domestic fuel oil turbidity test are inadequate, easily cause oil pump stuck short working life with filter screen, 2. under fuel tank low oil level state, most of pump housing of fuel pump can expose, can not fine realization dispel the heat, can cause that oil pump is impaired, the life-span reduces, 3. under fuel tank low oil level state, if automobile travels in the road conditions of jolting, at this moment oil pump filler opening disengaging fuel oil can easily occur and cause fuel feeding unstable, directly affect the motor car engine normal operation.
Summary of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of long service life, good heat dissipation, the stable band cascade filtration fuel oil pump assembly of fuel feeding.
The technological scheme that the utility model is taked:
Band cascade filtration fuel oil pump assembly, comprise fuel pump and filter screen, it is characterized in that: fuel pump is located in the oil-storing barrel, fuel pump has filler opening, main oil outlet and an oil outlet, filter screen comprises one-level coarse filtration and the filter of secondary essence, and the one-level coarse filtration places outside the oil-storing barrel and liquid jetting device joins, and liquid jetting device places in the oil-storing barrel, the jet import of liquid jetting device is joined with an oil outlet, and the filter of secondary essence places in the oil-storing barrel joins with filler opening.Filler opening is positioned at the bottom of fuel pump, and main oil outlet is positioned at the top of fuel pump.
After adopting technique scheme, the useful technique effect that the utility model can be realized is: 1. since fuel oil by the twice strainer filtering, shared the filtration duty that original one filter screen born, so filter screen is difficult for blocking, increase filter screen working life, also have, because fuel oil is through the filter of secondary essence, so the fuel oil turbidity test improve, oil pump is difficult for stuck, and 2. oil-storing barrel has oil storage function, so can make oil pump under fuel tank low oil level state, also can be immersed in to greatest extent heat radiation in the oil, 3. under fuel tank low oil level state, even automobile does not break away from fuel oil all the time at the road conditions of the jolting oil pump filler opening that travels yet, guarantee the stability of fuel feeding.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, and the below further describes each details and the working principle thereof of embodiment more by reference to the accompanying drawings.
As shown in the figure, band cascade filtration fuel oil pump assembly of the present utility model, comprise fuel pump 1 and filter screen, fuel pump 1 is located in the oil-storing barrel 2, fuel pump 1 has filler opening 11, main oil outlet 8 and an oil outlet 9, filler opening 11 is positioned at the fuel pump bottom, main oil outlet 8 and an oil outlet 9 are positioned at the fuel pump top, oil pump 1 is from filler opening 11 oil-feeds, pump is oily outward with an oil outlet 9 from main oil outlet 8, filter screen comprises one-level coarse filtration 4 and secondary essence filter 3, one-level coarse filtration 4 places outside the oil-storing barrel 2 and liquid jetting device 10 joins, and liquid jetting device 10 places in the oil-storing barrel 2, and an oil outlet 9 of the jet import of liquid jetting device 10 and oil pump joins by oil pipe 12, the jet exit of liquid jetting device 10 is aimed in the oil-storing barrel 2, and secondary essence filter 3 places in the oil-storing barrel 2 joins with filler opening 11.During work, fuel pump 1 is pump oil outward, the pressure oil of main oil outlet 8 is got the fuel pipe of oil sprayer, supply with the fuel oil of oil sprayer certain pressure, oil sprayer drives motor car engine and carries out work according to the instruction oil spout of ECU, and the pressure oil of oil outlet 9 enters the bottom and goes out from liquid jetting device 10 tops, form negative pressure and make the interior fuel oil of fuel tank in one-level coarse filtration 4 enters into oil-storing barrel 2, in oil-storing barrel, fuel oil enters fuel pump through secondary essence filter 3 filler openings 11 from fuel pump.Because the oil storage function of oil-storing barrel, so oil pump also can be immersed in to greatest extent heat radiation in the oil under fuel tank low oil level state, even automobile does not break away from fuel oil all the time at the travel filler opening of oil pump of the road conditions of jolting yet, guarantee the stability of fuel feeding.
Claims (2)
1. be with the cascade filtration fuel oil pump assembly, comprise fuel pump and filter screen, it is characterized in that: fuel pump is located in the oil-storing barrel, fuel pump has filler opening, main oil outlet and an oil outlet, filter screen comprises one-level coarse filtration and the filter of secondary essence, and the one-level coarse filtration places outside the oil-storing barrel and liquid jetting device joins, and liquid jetting device places in the oil-storing barrel, the jet import of liquid jetting device is joined with an oil outlet, and the filter of secondary essence places in the oil-storing barrel joins with filler opening.
