Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. In the embodiment, the fuel guide electronic injection fuel pump assembly comprises two oil pumps 1, an oil outlet pipe 2 and an oil return pipe 3, wherein the two oil pumps 1 are respectively installed in an oil tank A4 and an oil tank B5, the oil pump 1 comprises an electronic injection pump 6, an oil storage barrel 7, a pressure valve 8 and an injection pump 9, the electronic injection pump 6, the pressure valve 8 and the injection pump 9 are installed in the oil storage barrel 7, and the oil storage barrel 7 is installed in the oil tank; the oil outlet pipe 2 is provided with two oil inlet interfaces and an oil outlet interface, the oil return pipe 3 is provided with an oil return interface and two oil outlet interfaces, the oil outlet ports of the oil outlet pipe 2 are respectively connected with the oil outlet nozzles of the electric injection pump 6 in the A oil tank 4 and the B oil tank 5, the oil outlet ports of the oil outlet pipe 2 are connected with the oil inlet of the engine 11, the oil return inlets of the pressure valve 8 in the A oil tank 4 and the B oil tank 5 are respectively connected with the two oil outlet interfaces of the oil return pipe 3, the oil return ports of the oil return pipe 3 are connected with the oil return port of the engine, the electric injection pump 6 is further provided with a small oil nozzle 10 positioned on one side of the oil outlet nozzle, the small oil nozzle 10 is connected with a driving port 12 of the pressure valve 8 and used for driving the pressure valve 8 to be opened, and.
As a further improved embodiment, the pressure valve 8 is a low-pressure switch type pressure regulating valve.
As a specific embodiment of further improvement, the maximum blocking pressure of the pressure valve 8 is 200 kPa. The pressure of the automobile oil return pipe 3 exceeds 200kPa, the two pressure valves 8 are opened simultaneously to achieve the purpose of rapid pressure relief, after the pressure is less than 200kPa, the valve of the fuel pump 1 assembly which is not electrified is closed, and the fuel oil still returns to the oil tank of the electronic injection pump 6 assembly which is electrified.
The utility model discloses an operating principle, by car ECU control A oil tank 4 or the 5 circular telegrams of B oil tank use, when using 4 fuel of A oil tank, return oil pipe 3 and open, the fuel that does not consume gets into A oil tank 4 through returning oil pipe 3, can not lead to 5 oil level display errors of B oil tank. When the fuel in the oil tank A4 is insufficient, the fuel pressure is reduced, the pressure valve 8 cannot be opened, the oil return pipe 3 is closed, the automobile ECU detects that the pressure signal of the oil way is reduced, and the circuit can be directly switched to the oil tank B5, so that the normal running of the automobile is ensured.
When the fuel pump 1 works, fuel oil flows out from a small nozzle 10 on the electronic injection pump 6 and flows into the pressure valve 8 by the pressure valve 8, the pressure valve 8 is opened by the pressure of the fuel oil, so that a fuel oil loop is connected, the unconsumed fuel oil returns to the fuel tank, and when the pressure in the oil return pipe 3 exceeds 200kPa, the valve is also automatically opened, so that the oil return efficiency is ensured, and the safety of the oil return pipe 3 is ensured. Therefore, fuel can be seamlessly switched between the main oil tank A4 and the main oil tank B5, higher pressure is not required to be built, any electronic control mode is not adopted, the cost is saved, the durability is ensured, and the production efficiency and the production stability are improved.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
