Abstract
The utility model relates to an electric fuel pump assembly which comprises a flange plate, a pump core, a bottom barrel, a sensor, an upper filter screen bracket and a lower filter screen, wherein the flange plate is connected with the bottom barrel, the pump core is arranged in the bottom barrel, the sensor is connected to the bottom barrel, the upper filter screen bracket is arranged between the bottom barrel and the pump core and connected with the bottom barrel, the lower filter screen is connected to the bottom of the bottom barrel, the bottom of the pump core is provided with a pump core through hole, the lower filter screen is provided with an exhaust passage, and the pump core through hole is communicated with the exhaust passage. For the electric fuel pump assembly, the through hole and the exhaust passage are arranged at the bottom of the pump core and on the lower filter screen respectively, and gas generated by the pump core is discharged into an oil tank, thus removing gas mixed in the fuel oil, greatly lowering noise and having low noise. In addition, the quality of the fuel oil is effectively promoted, the influence on the performance of an automobile fuel oil system due to the gas mixed in the fuel oil is avoided, and the stable performance of the automobile fuel oil system is ensured.
Description
Technical field
The utility model relates to a kind of electric fuel pump assembly, relates in particular to the electric fuel pump assembly of the low and stable performance of a kind of noise.
Background technique
Electric fuel pump assembly is installed on the automotive oil tank, is vehicle fuel supply system fuel feeding.When fuel oil is inhaled into the pump core of high flow capacity, can produce a large amount of gas, these gases can be taken to oil outlet by the pump core with fuel oil, arrive the fuel supply system of automobile.Owing to there is gas to be mixed in the fuel oil, fuel oil can produce the sound of " thumping " in combustion process, make that the noise of electric fuel pump assembly is big.In addition, the sneaking into of gas reduced fuel oil purity, influenced the normal combustion of fuel oil, makes the oil-fired system unstable properties of automobile.
The model utility content
The purpose of this utility model is to provide a kind of electric fuel pump assembly, to solve the technical problem of the big and unstable properties of electric fuel pump assembly noise in the prior art.
Be the purpose on reaching, the utility model provides a kind of electric fuel pump assembly, comprise: flange plate, pump core, end bucket, sensor, upper filter screen support and lower filter screen, flange plate is connected with end bucket, and the pump core is arranged on bucket inside, the end, sensor is connected to end bucket, the upper filter screen support is arranged between end bucket and the pump core and is connected with end bucket, and lower filter screen is connected to bucket bottom, the end, and pump core bottom is provided with a pump core through hole, lower filter screen is provided with an exhaust passage, and pump core through hole is communicated with the exhaust passage.
According to the described electric fuel pump assembly of the utility model preferred embodiment, the exhaust passage further comprises through hole and lower through-hole, and last through hole is connected with pump core through hole, and lower through-hole is communicated with fuel tank.
The utility model improves existing electric fuel pump assembly, on pump core bottom and lower filter screen through hole and exhaust passage are set respectively, the gas that the pump core is produced is discharged in the fuel tank, makes no longer to be mingled with gas in the fuel oil, greatly reduce noise, the electric fuel pump assembly noise is little.And, promoted the quality of fuel oil effectively, avoided because of being mingled with the influence that gas causes in the fuel oil the vehicle fuel systematic function, guaranteed the stable of vehicle fuel systematic function.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1 to Fig. 3, a kind of electric fuel pump assembly comprises flange plate 10, pump core 20, end bucket 30, sensor 40, upper filter screen support 50 and lower filter screen 60, and flange plate 10 is connected with end bucket 30, pump core 20 is arranged on end bucket 10 inside, and its bottom is provided with pump core through hole 201.Sensor 40 is connected to end bucket 30, upper filter screen support 50 is arranged between end bucket 30 and the pump core 20 and is connected with end bucket 30, lower filter screen 60 is connected to end bucket 30 bottoms, lower filter screen 60 is provided with exhaust passage 601, exhaust passage 601 further comprises through hole 602 and lower through-hole 603, last through hole 601 is connected with pump core through hole 201, and lower through-hole 603 is communicated with fuel tank, and the gas that pump core 20 produces is discharged into the fuel tank from this hole.
Working procedure of the present utility model is as follows:
After connecting power supply, fuel oil is under the running of the fuel pump pump core 20 of high flow capacity drives, enter end bucket by being installed in end bucket 30 following lower filter screens 60, pass through the filtration of upper filter screen support 50 again, enter the filler opening 202 of pump core 20,, arrive the oil outlet of pump core through pump core 20, arrive the fuel supply system of automobile, system provides fuel oil for vehicle fuel.The gas that pump core 20 produces in extracting the process of fuel oil enters fuel delivery discharge passage 601 on the lower filter screen 60 by the pump core through hole 201 of pump core 20 bottoms, is discharged in the fuel oil fuel tank that electric fuel pump assembly places by lower through-hole 603 at last.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the present utility model.
