Abstract
The utility model relates to a two-stage type fuel pump, and belongs to the technical field of automobile parts. The two-stage type fuel pump comprises a fuel pump body. The two ends of the fuel pump body are provided with a front pump cover and a rear end cover respectively, wherein the front pump cover is provided with a fuel inlet, and the rear end cover is provided with a fuel outlet. The fuel inlet is sequentially and coaxially connected with a primary pump, a main fuel delivery pump and a motor. The main fuel delivery pump is connected with the fuel outlet through a pipeline, a pressure sensor for measuring fuel pressure is arranged on the fuel outlet, and the other end of the pressure sensor is sequentially connected with a motor controller and the motor. The two-stage type fuel pump has the advantages of being simple in structure, good in fuel delivery performance and high in pressure regulating accuracy.
Description
Technical field
The utility model relates to a kind of stage type fuel pump, belongs to technical field of automobile parts.
Background technique
Automobile fuel pump is one of fundamental composition of electro jet car fuel injection system, effect is being transported in fuel supply line after fuel oil sucking-off from fuel tank, pressurization, and this stage type fuel pump can and fuel pressure regulator cooperate the certain fuel pressure of generation.The defect that existing fuel pump ubiquity flow is low, performance of feeding oil is poor, can't accurately control oil transportation amount, tends to the phenomenon that occurs that fuel feeding is excessive, has wasted greatly oily resource.
Summary of the invention
The problem and the deficiency that exist for above-mentioned prior art, the utility model provides a kind of stage type fuel pump.That this stage type fuel pump has is simple in structure, performance of feeding oil good, pressure regulation precision is high.The utility model is achieved through the following technical solutions.
A kind of stage type fuel pump, comprise fuel pump body 1, described fuel pump body 1 two ends are installed respectively and are provided with the front pump cover 2 of filler opening 21 and the rear end cover 6 of oil outlet 61, filler opening 21 is order coaxial connection backing pump 3, main oil transfer pump 4, motor 5 successively, main oil transfer pump 4 is connected with oil outlet 61 by pipeline, oil outlet 61 places are provided with the pressure transducer of measuring oil pressure, and the other end order of pressure transducer is connected with electric machine controller, motor 5.
Described backing pump 3 is vane pump.
Described main oil transfer pump 4 is roller pump.
This stage type fuel pump working principle: motor 5 drive backing pump 3 by the oil at filler opening 21 places with low-pressure delivery to main oil transfer pump 4 places, by main oil transfer pump 4 with High voltage output, the pressure transducer at oil outlet 61 places can detect oil pressure constantly, electric machine controller regulates motor 5 rotating speed control oil pump capacity according to oil pressure value, to meet the needs of automobile different rotating speeds, reasonably arrange the output of oil mass.
The beneficial effects of the utility model are: (1) compared with prior art, this stage type fuel pump is provided with backing pump and main oil transfer pump simultaneously, and oil pump capacity is significantly improved, and performance of feeding oil is good; (2) this stage type fuel pump is also provided with the pressure transducer of measuring oil pressure at oil outlet place, and electric machine controller can be controlled the rotating speed of motor according to the measurement numerical value of pressure transducer, reached the good control to oil pump capacity; (3) this stage type fuel pump also have simple in structure, performance of feeding oil good, pressure regulation precision advantages of higher.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: 1-fuel pump body, 2-front pump cover, 21-filler opening, 3-backing pump, the main oil transfer pump of 4-, 5-motor, 6-rear end cover, 61-oil outlet.
Embodiment
