Abstract
The invention relates to an oil tank fuel pump system assembly. The oil tank fuel pump system assembly comprises a main oil tank, an auxiliary oil tank and a fuel pump assembly. The side of the main oil tank is connected with the auxiliary oil tank; the fuel pump assembly is installed in the main oil tank and comprises an oil storage barrel, an oil introducing device is arranged in the middle of the oil storage barrel, an oil introducing pipe is arranged in the oil introducing device, one end of the oil introducing pipe extends into the auxiliary oil tank, the other end of the oil introducing pipe is connected with an oil outlet pipe through a tee joint, an air suction device is arranged in the middle of the oil introducing pipe and is a double-cross-type pipeline, but the inner diameter of the air suction device is smaller than that of the oil introducing pipe. Oil far in the auxiliary oil tank can be smoothly sucked out by a fuel pump at a low oil level, so that the service time of refueling each time is prolonged, noise generated when the oil level is low is lowered, and the driving and riding comfort level of personnel is improved.
Description
Technical field
The present invention relates to automobile fuel pump technical field, specifically a kind of oil tank fuel pumping system assembly.
Background technique
Automotive oil tank is designed with main fuel tank and drop tank two-part usually according to vehicle body space situation, and fuel pump is generally all arranged on main fuel tank, because the space of main fuel tank is larger, lower fuel pump can be placed, but when fuel level in tank is lower, fuel pump oil suction efficiency is not high, and noise is larger, oil particularly in drop tank is difficult to be inhaled into because inner fuel pump is comparatively far away, when therefore usually also remaining quite a few fuel oil in fuel tank, do not catch up with the consumption of motor, in fact, if by its Fuel Oil Remaining added together for the fuel oil in main fuel tank and drop tank or many, this has just occurred that all can remain a part of fuel oil refuels with regard to needs at every turn, and at the larger noise of the generation that oil level is lower, thus the comfort level that the personnel reduced drive.
Summary of the invention
The object of the invention is to be to provide a kind of oil tank fuel pumping system assembly, can when oil level is very low by smooth for the oil in drop tank sucking-off, thus extend each service time of refueling, the noise produced when reduction oil level is lower simultaneously, thus the comfort level that the personnel improved drive.
The object of the invention is to be achieved through the following technical solutions: it comprises main fuel tank, drop tank, fuel oil pump assembly, described main fuel tank side is connected with drop tank, fuel oil pump assembly is arranged in main fuel tank, described fuel oil pump assembly comprises oil-storing barrel, oil-drawing device is provided with in the middle part of oil-storing barrel, be provided with in oil-drawing device and draw oil pipe, drawing oil pipe one end extends in drop tank, the other end is connected with oil outlet tube by threeway, described drawing in the middle of oil pipe is provided with suction device, described suction device is diesis type pipeline, but its internal diameter is less than the internal diameter drawing oil pipe.
Fuel pump of the present invention when oil level is very low by smooth for the oil in drop tank sucking-off, thus can extend each service time of refueling, the noise produced when reduction oil level is lower simultaneously, thus the comfort level that the personnel improved drive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of fuel oil pump assembly of the present invention;
Fig. 3 is the partial schematic diagram drawing oil pipe and suction device in fuel oil pump assembly of the present invention.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, technological scheme of the present invention is further described in detail.
As illustrated in the accompanying drawings from 1 to 3, the present invention is a kind of oil tank fuel pumping system assembly.It comprises main fuel tank 1, drop tank 2, fuel oil pump assembly 3, described main fuel tank 1 side is connected with drop tank 2, fuel oil pump assembly 3 is arranged in main fuel tank 1, described fuel oil pump assembly 3 comprises oil-storing barrel 4, oil-drawing device 5 is provided with in the middle part of oil-storing barrel 4, be provided with in oil-drawing device 5 and draw oil pipe 6, drawing oil pipe 6 one end extends in drop tank, the other end is connected with oil outlet tube 7 by threeway 8, described drawing in the middle of oil pipe 6 is provided with suction device 9, described suction device 9 is diesis type pipeline, but its internal diameter is less than the internal diameter drawing oil pipe 6.
The present invention extends to drop tank by drawing oil pipe one end, its main purpose is arranged in drop tank by inlet port, suction suffered by oil in such drop tank is maximum, oil pipe will be drawn additionally by three-way device to be connected with oil outlet tube, the flow velocity in oil outlet tube can be utilized to drive the flowing of drawing fuel oil in oil pipe, increase the flow velocity drawing fuel oil in oil pipe, auxiliary by the oil introducing oil-storing barrel in drop tank, described suction device, it is the suction effect to surrounding fluid utilizing increase rate of flow of fluid and produce, by changing the internal diameter of oil-absorbing process fuel sucking pipe, in the steady flow of same flow pipe, caliber attenuate place flow velocity increase and pressure reduce, when pressure is reduced to the pressure lower than surrounding fluid, namely surrounding fluid flows into this place, therefore increase flow velocity by oil outlet tube and change and draw oil pipe line internal diameter internal diameter and under increasing the double action of flow velocity, fuel pump can when oil level is very low by smooth for the oil in drop tank sucking-off, thus extend each service time of refueling, the noise produced when reduction oil level is lower simultaneously, thus the comfort level that the personnel improved drive.
