Abstract

The utility model relates to an oil tank supercharged oil supply device, which comprises a fuel oil pump and a small oil tank, and is characterized in that the fuel oil pump and the small oil tank are installed in a tank bay; an oil delivery control valve and a check valve are arranged in the pipeline between the fuel oil pump and the small oil tank; the output pipe of the small oil tank is connected to the outside of the tank bay and with an engine; two connecting pipes are installed on the upper part of the small oil tank and connected to the outside of the oil tank; a pressure relief valve and a check valve are respectively installed on the two connecting pipes; the oil delivery control valve is connected with a fluidic sensor; the fuel oil pump is placed at the inner bottom of the tank bay. Through using the oil level controller and the oil delivery control valve to control the level of oil in the small oil tank, the utility model has the advantages that the fuel oil tank with noncircular cross section which cannot bear internal pressure can use the method of air entraining and supercharging to supply oil, the combined method of air entraining and supercharging is used for the fuel oil pump and the small oil tank to supply oil to the engine, the requirement on the engine oil supply is satisfied and the weight of the oil tank is reduced.

Description

The fuel-tank pressurization feed apparatus
Technical field
The utility model relates to the aviation power fuel supply system, particularly relates to the fuel-tank pressurization feed apparatus.
Background technology
Some small aero must be utilized the fuel system ability normal operation of bleed supercharging, yet sometimes in order to satisfy the general shape design, fuel tank need be designed to bear the on-circular cross-section of pressing than imperial palace.Present fuel system is simple bleed supercharging or oil pump feed mode mostly, and simple bleed supercharging fuel feeding can make the fuel tank configuration design can't satisfy general requirement, and the mode of simple oil pump feed can't satisfy the engine oil requirement.
Summary of the invention
The purpose of this utility model is, utilizes fuel charger and little fuel tank bleed supercharging array mode to engine oil, solves the problem that the on-circular cross-section fuel tank is pressed in can not bearing, and satisfies the requirement of engine oil simultaneously again.
The utility model by the following technical solutions, the fuel-tank pressurization feed apparatus, form by fuel charger, little fuel tank, it is characterized in that fuel charger and little fuel tank are installed in the tank bay, fuel charger is connected to oil transportation control cock and check valve to the connecting line of little fuel tank, the delivery pipe of little fuel tank is connected to outside the tank bay, connect driving engine, two connection pipes also are equipped with to fuel tank in the top of little fuel tank, and these two connection pipes are separately installed with pressure-relief valve and check valve; Described oil transportation control cock connects fluidic sensor; Described fuel charger is placed on the position of tank bay inner bottom part.
The beneficial effects of the utility model are, control pasta in the little fuel tank by pasta controller and oil transportation control cock, thereby the on-circular cross-section fuel tank of pressing in realizing bearing utilizes bleed supercharging mode fuel feeding, adopt fuel charger and little fuel tank bleed supercharging array mode to engine oil, can satisfy the engine oil requirement, alleviate fuel tank weight.

The specific embodiment
Now 1 the utility model is described in further detail in conjunction with the accompanying drawings, the fuel-tank pressurization feed apparatus, form by fuel charger 2, little fuel tank 3, fuel charger 2 and little fuel tank 3 are installed in the tank bay 1, fuel charger 2 is connected to oil transportation control cock 6 and check valve 7 to the connecting line of little fuel tank 3, the delivery pipe of little fuel tank 3 is connected to outside the tank bay, connects driving engine, two connection pipes also are equipped with to fuel tank in the top of little fuel tank 3, and these two connection pipes are separately installed with pressure-relief valve 4 and check valve 5; Described oil transportation control cock 6 connects fluidic sensor 8; Described fuel charger 2 is placed on the position of tank bay 1 inner bottom part.
The specific embodiment is as follows: pressure-relief valve 4 models that the utility model adopted are that QYF-78, check valve 5,7 models are that QXF-87, fluidic sensor 8 models are FR-708.
Fuel charger 2 is placed on the lower position of tank bay 1, by fuel charger 2 oily supercharging is exported again; Arrange little fuel tank 3 at the medium position of tank bay 1, the cross section of little fuel tank 3 is the circle of φ 300mm, and its two ends are ellipsoid surface, makes it to bear the interior pressure of 0.3MPa at least.Fuel charger 2 is transported to little fuel tank 3 by delivery line with the fuel oil in the tank bay 1, little fuel tank 3 utilizes engine bleed to be fuel pressurization, a check valve 5 is set on bleed air line, prevent that the fuel oil in the little fuel tank 3 from entering driving engine by bleed air line, for making the interior pressure of the pressurized energy maintenance 0.14MPa of institute in the little fuel tank 3, little fuel tank 3 also is equipped with the pipeline of another band pressure-relief valve 4, pressure-relief valve 4 is adjusted to 0.14MPa, when pressure is excessive, lay down a part of pressure, guarantee to provide the fuel oil of convenient pressure flow for driving engine.The pressure that the charge oil pressure of fuel charger 2 keeps greater than pressure-relief valve 4, fuel supply flow rate is greater than required fuel flow under the various mode of operations of driving engine. and enter bleed air line in order to prevent the system work process IFO intermediate fuel oil to be full of little fuel tank 3 and stop up gas circuit, in little fuel tank 3, fluidic sensor 8 is set, when the pasta in the little fuel tank 3 arrives the height of fluidic sensor 8 settings, fluidic sensor 8 is started working, control is placed in the oil transportation control cock 6 on fuel charger 2 delivery lines, and cut-out oil circuit, stop to little fuel tank 3 oil transportations, when the pasta in the little fuel tank 3 is lower than a certain height, fluidic sensor 8 is handled control cock 6 and is opened oil circuit, continues to little fuel tank 3 fuel feeding.A check valve 7 is set on the delivery line of centrifugal pump 2, prevents fuel oil and pressed gas refluence oil-feed tank cabin 1 in the little fuel tank 3.
Utilize fuel charger 2 and little fuel tank 3 bleed supercharging array modes to engine oil, by the pasta in fluidic sensor 8 and the little fuel tank 3 of oil transportation control cock 6 controls, thereby the on-circular cross-section fuel tank of pressing in realizing bearing utilizes bleed supercharging mode fuel feeding, adopt fuel charger 2 and little fuel tank 3 bleed supercharging array modes to engine oil, the on-circular cross-section fuel tank can be solved and interior problem of pressing can not be born, also can satisfy the fuel feeding requirement of driving engine, alleviate fuel tank weight.
