Abstract
The utility model discloses a fuel oil pump assembly with an oil storage barrel. The fuel oil pump assembly with the oil storage barrel comprises a fuel oil pump and filter screens. The fuel oil pump assembly with the oil storage barrel is characterized in that the fuel oil pump is arranged in the oil storage barrel, the fuel oil pump comprises a first oil inlet, a second oil inlet, a first oil outlet and a second 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 the first oil inlet, and the secondary refined filter screen is placed in the oil storage barrel and is connected with the second oil inlet. The fuel oil pump assembly with the oil storage barrel 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 inlets of the fuel oil pump are 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 the stuck and filter screen weak point in working life of oil pump, 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 occur easily 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 oil-storing barrel fuel oil pump assembly of fuel feeding.
The technological scheme that the utility model is taked:
Band oil-storing barrel 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 the first filler opening, the second filler opening, the first oil outlet and the second oil outlet, filter screen comprises one-level coarse filtration and the smart filter of secondary, the one-level coarse filtration places outside the oil-storing barrel joins with the first filler opening, and the smart filter of secondary places in the oil-storing barrel and the second filler opening joins.The first filler opening, the second filler opening and the first oil outlet are positioned at the bottom of fuel pump, and the second 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 smart filter of secondary, 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 oil-storing barrel 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 adopts the double flute electric-spraying fuel pump, the double flute electric-spraying fuel pump has the first filler opening 7, the second filler opening 6, the first oil outlet and the second oil outlet 5, the first filler opening 7, the second filler opening 6 and the first oil outlet are positioned at the bottom of fuel pump 1, the second oil outlet 5 is positioned at the top of fuel pump 1, the first filler opening 7 and the first oil outlet are at the oily passage of the oil pump 1 interior formation bearing part in the oil pump, it enters the bottom and goes out from the bottom of oil pump 1, the second filler opening 6 and the second oil outlet 5 pass through bearing part in the oil pump from top to bottom at the oily passage of oil pump 1 interior formation, filter screen comprises one-level coarse filtration 4 and the smart filter 3 of secondary, one-level coarse filtration 4 places outside the oil-storing barrel 2 joins with the first filler opening 7, and the smart filter 3 of secondary places in the oil-storing barrel 2 and the second filler opening 6 joins.During work, fuel oil in the fuel tank enters through first filler opening 7 of one-level coarse filtration 4 from fuel pump, (these road binders turbidity test are not high in the first oil outlet of fuel pump is got oil-storing barrel 2, but the bearing part in the oil pump, so can not cause the oil pump stuck phenomenon), then the fuel oil in the oil-storing barrel 2 enters through the smart filter of secondary 3 the second filler openings 6 from fuel pump, (this road binders is through the smart filter of one-level coarse filtration and secondary to get the fuel pipe of oil sprayer from the second oil outlet 5 of fuel pump, the fuel oil turbidity test are high), 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.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 oil-storing barrel 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 the first filler opening, the second filler opening, the first oil outlet and the second oil outlet, filter screen comprises one-level coarse filtration and the smart filter of secondary, the one-level coarse filtration places outside the oil-storing barrel joins with the first filler opening, and the smart filter of secondary places in the oil-storing barrel and the second filler opening joins.
