Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
Embodiment 1
A kind of oil-return type oil transportation control system, including main fuel tank, oil transportation case 10, fuel pump 5, jet pump 8 and oil signal to the greatest extent
Device 9, main fuel tank are divided into the preceding main fuel tank 2 and rear main fuel tank 6 being connected to by oil return hole 3, lead between preceding main fuel tank 2 and oil transportation case 10
The connection of oil return pipe 1 is crossed, before one end of oil return pipe 1 extends in main fuel tank 2, the position of oil return hole 3 is higher than the ozzle of oil return pipe 1,
It is equipped with jet pump 8 and oil signalling means 9 to the greatest extent in oil transportation case 10, is equipped with fuel pump 5 in rear main fuel tank 6, fuel pump 5 passes through the first oil transportation
Pipeline 11 is connect with jet pump 8, and jet pump 8 is connected to by the second pipeline road 12 with rear main fuel tank 6.
The bottom surface of preceding main fuel tank 2 is higher than the bottom surface of rear main fuel tank 6, is additionally provided with first between preceding main fuel tank 2 and rear main fuel tank 6
Check valve 4, the first check valve 4 are located at the lower section of oil return hole 3, and close to the bottom position of preceding main fuel tank 2, design in this way is flying
When machine makees Motorized dive flight, main fuel tank 6 after the fuel oil of main fuel tank 2 flows into before making, while preventing rear 6 fuel oil of main fuel tank from flowing backward to
Preceding main fuel tank 2, that is, when the pasta of main fuel tank is lower than the first check valve after guaranteeing, the fuel oil in preceding main fuel tank can be flowed into all
It is used in main fuel tank for engine afterwards.
The inlet that second pipeline road 12 enters rear main fuel tank 6 is equipped with the second check valve 7, prevents in jet pump not work
When making, fuel oil is flowed backward in oil transportation case 10 in rear main fuel tank 6.
Fuel pump 5 connects engine by third pipeline road 13, conveys fuel oil for engine.
Working principle is as follows:
Main fuel tank is divided into preceding main fuel tank 2 and rear main fuel tank 6, connects fuel pump 5 and starts oil transportation.
(1) when current 2 pasta of main fuel tank is higher than the ozzle of oil return pipe 1, the pressurized fuel oil of fuel pump 5 enters oil transportation case 10
