Abstract
The utility model relates to a low pressure fuel oil system capable of high-precision filter diesel and is characterized in that a huge oil tank connects to one end of the electric oil-conveying pump through an oil pipe, the other end of the electric oil-conveying pump joins with one end of the oil-water separator by an oil pipe, the other end of the oil-water separator joins with a centrifugal filter through an oil pipe, the outlet port of the centrifugal filter connects to a small oil tank on one side through an oil pipe, the other side of the small oil tank joins with a mechanical oil-conveying pump by an oil pipe, the outlet port of the mechanical oil-conveying pump is in connection with a fuel-oil fine filter by an pipe and the oil outlet port of the fuel oil fine filter joins with a high pressure oil pump. The low pressure fuel oil system enables the clean diesel into an electrical-control common-rail system, guarantees the long and reliable work of the electrical-control common-rail system, reduces the maintenance costs for the user, eliminates complaints of the user and improves the adaptability of the commercial vehicles on the domestic diesel.
Description
Technical field
The utility model relates to a kind of low pressure fuel system of high-precision filtration diesel oil, belongs to the technical field of commercial car design.
Background technique
The low pressure fuel system of domestic commercial vehicle adopts oil and water seperator oil fine cleaner to filter diesel oil.Because China Diesel is of poor quality, the diesel oil after this usual manner filters can not satisfy the requirement of electric-controlled co-rail system.This diesel oil enters the inordinate wear that can cause system unit in the engine electric-controlled common rail system, and especially the too early wearing and tearing of electric-controlled fuel injector can cause ejection function to lose efficacy.At this moment user's oil sprayer that can only more renew causes very large economic loss to the user, and the user is very large to this complaint.
Summary of the invention
The purpose of this utility model provides a kind of low pressure fuel system of high-precision filtration diesel oil, and it extract to be carried diesel oil, diesel oil to advance to become clean diesel behind oil and water seperator, the spin-on filter from large tank by electrically operated fuel pump and is stored in the little fuel tank; Mechanical oil transfer pump extracts conveying diesel oil in little fuel tank, make the diesel oil of cleaning enter the electric-controlled co-rail system, guaranteed the permanent reliably work of electric-controlled co-rail system, reduced user's maintenance expenses, eliminate user's complaint, improved the adaptability of commercial car to China Diesel.
The technical solution of the utility model is achieved in that a kind of low pressure fuel system of high-precision filtration diesel oil, it is characterized in that: large tank connects electrically operated fuel pump one end by oil pipe, the electrically operated fuel pump the other end is connected with oil and water seperator one end by oil pipe, the oil and water seperator the other end connects spin-on filter by oil pipe, the spin-on filter oil outlet connects little fuel tank by oil pipe, the little fuel tank the other end connects mechanical oil transfer pump by oil pipe, mechanical oil transfer pump oil transportation mouth connects fuel oil fine filter by oil pipe, and oil outlet connected high pressure oil pump after fuel oil fine filter filtered.
Good effect of the present utility model is extract to carry diesel oil, diesel oil to advance to become clean diesel behind oil and water seperator, the spin-on filter from large tank by electrically operated fuel pump to be stored in the little fuel tank; Mechanical oil transfer pump extracts conveying diesel oil in little fuel tank, make the diesel oil of cleaning enter the electric-controlled co-rail system, guaranteed the permanent reliably work of electric-controlled co-rail system, reduced user's maintenance expenses, eliminate user's complaint, improved the adaptability of commercial car to China Diesel.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment: as shown in Figure 1, a kind of low pressure fuel system of high-precision filtration diesel oil, it is characterized in that: large tank 1 connects electrically operated fuel pump 2 one ends by oil pipe, electrically operated fuel pump 2 the other ends are connected with oil and water seperator 3 one ends by oil pipe, oil and water seperator 3 the other ends connect spin-on filter 4 by oil pipe, spin-on filter 4 oil outlets connect little fuel tank 5 by oil pipe, little fuel tank 5 the other ends connect mechanical oil transfer pump 6 by oil pipe, mechanical oil transfer pump 6 oil transportation mouths connect fuel oil fine filter 7 by oil pipe, and oil outlet connected high pressure oil pump 8 after fuel oil fine filter 7 filtered.
[0008]As shown in Figure 1, electrically operated fuel pump 2 flows to oil and water seperator 3 to the diesel oil draw out of 1 li of large tank, the filter precision of oil and water seperator 3: the filter efficiency of (3～5) μ m impurity 〉=10%; The filter efficiency of 30 μ m impurity 〉=99%; Moisture is from efficient 〉=93%.Diesel oil after preliminary the filtration enters spin-on filter 4, the filter precision of spin-on filter 4: the filter efficiency of (3～5) μ m impurity 〉=99%.Clean diesel after the smart filter enters little fuel tank 5.Mechanical oil transfer pump 6 flows to fuel oil fine filter 7 to the diesel oil draw out of cleaning from little fuel tank, the filter precision of fuel oil fine filter 7: the filter efficiency of (3～5) μ m impurity 〉=98.6%, clean diesel is supplied with the high pressure oil pump of electric-controlled co-rail system at last, carries out cycle of higher pressure.
