Description
Technical field
The present invention relates to aircraft fuel system technical fields, more particularly to fuselage fuel cell fuel delivery device.
Background technique
To guarantee flight safety, the oil transportation of airframe fuel tank considers that safety margin designs.In oil transfer pump shape working properly
Power oil transportation is used under state, after oil transportation failure of pump, oil tank fuel can also transport to consumption fuel tank by gravity, guarantee fuel tank intermediate fuel oil
It can use.To avoid two sets of fuel transfer systems from interfering with each other, two circuits are generally used.But for certain light aerocrafts, by channel
Space limitation does not have two circuits conditions of laying.
Summary of the invention
In order to solve the above technical problems, it is mutual to avoid two sets of fuel transfer systems the present invention provides fuselage fuel cell fuel delivery device
It mutually interferes, and meets space installation question.
Fuselage fuel cell fuel delivery device, including check valve one, oil transfer pump, check valve two, check valve three, float-controlled valve, venthole
With small fuel tank, fuel tank internal is arranged under consumption in small fuel tank, and preceding group of fuel tank is connect by pipeline with small fuel tank, and rear fuel tank of organizing passes through
Pipeline is connect with small fuel tank, and small fuel tank is connect by pipeline with consumption top tank, and consumption top tank passes through pipeline and the lower oil of consumption
Case connection, check valve one are arranged in preceding group of fuel tank and lead on the pipeline of small fuel tank, and oil transfer pump is arranged in small fuel tank internal, check valve
Two, which are arranged in rear group of fuel tank, leads on the pipeline of small fuel tank, and the pipeline that small fuel tank leads to consumption top tank is arranged in check valve three
On, the piping connection that its underpart and small fuel tank in consumption top tank lead to consumption top tank, venthole setting is arranged in float-controlled valve
On small fuel tank top.
Further, which further includes check valve four, and check valve four, which is arranged, leads to consumption in small fuel tank
On the pipeline of lower fuel tank.
The present invention compares background technique advantageously: fuselage fuel cell fuel transfer system degree of physical is comprehensive, and power is defeated
Oil system and gravity fuel transfer system pipeline, attachment share completely, and a set of pipeline road, attachment is used only, especially suitable for arrangement
The occasion of space anxiety, also correspondingly reduces system cost, alleviates system weight.

Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and example is served only for explaining invention, not
For limiting the scope of the invention.
Fuselage fuel cell fuel delivery device, including it is check valve 1, oil transfer pump 2, check valve 23, check valve 34, float-controlled valve 6, logical
Fuel tank internal is arranged under consumption in stomata 7 and small fuel tank 8, small fuel tank 8, and preceding group of fuel tank is connect by pipeline with small fuel tank 8, and rear group
Fuel tank is connect by pipeline with small fuel tank 8, and small fuel tank 8 is connect by pipeline with consumption top tank, and consumption top tank passes through pipeline
It is connect with lower fuel tank is consumed, check valve 1 is arranged in preceding group of fuel tank and leads on the pipeline of small fuel tank 8, and oil transfer pump 2 is arranged in small oil
Inside case 8, check valve 23 is arranged in rear group of fuel tank and leads on the pipeline of small fuel tank 8, and the setting of check valve 34 is led in small fuel tank 8
On the pipeline for consuming top tank, the pipe that its underpart and small fuel tank 8 in consumption top tank lead to consumption top tank is arranged in float-controlled valve 6
Road connection, venthole 7 are arranged on small 8 top of fuel tank.
The fuselage fuel cell fuel delivery device further includes check valve 45, the setting of check valve 45 oil in the case where small fuel tank 8 leads to consumption
On the pipeline of case.Main purpose is to consume lower tank-level after oil transfer pump breaks down and begin to decline, until being lower than forward and backward group
Tank-level, pressure will be greater than consuming lower tank bottoms pressure in small fuel tank 8 at this time, be connected to small fuel tank 8 and consume lower fuel tank it
Between check valve 45 open, by the check valve to consuming lower fuel tank oil transportation in small fuel tank 8.
The operation principle of the present invention is that small fuel tank 8 is mounted in the lower fuel tank of consumption, forward and backward group of fuel tank is come from for receiving
Fuel oil, and oil transfer pump 2 is installed in small fuel tank 8.Venthole 7 is arranged in small 8 top of fuel tank, is connected to lower fuel tank is consumed, when oiling
Small fuel tank 8 may be implemented since small 8 capacity of fuel tank is smaller to ventilate, aperture metering function avoids under small fuel tank and consumption when oil transportation
Fuel tank is isobaric.When oil transfer pump 2 works normally, 8 pressure, which are less than, in small fuel tank consumes lower tank pressure, and check valve 45 is closed, small oil
Case 8 is isolated with lower fuel tank is consumed, and small 8 intermediate fuel oil of fuel tank is transported to consumption top tank by oil transfer pump 2, after Oil-gas Separation, then passes through company
Siphunculus transports to the lower fuel tank of consumption, can make to consume the higher pasta of lower fuel tank maintenance.The float-controlled valve 6 installed can be in consumption top tank
Control its fuel head.
After oil transfer pump breaks down, consumes lower tank-level and begin to decline, until being lower than forward and backward group of tank-level, at this time
Pressure will be greater than consuming lower tank bottoms pressure in small fuel tank 8, is connected to small fuel tank 8 and consumes the check valve 45 between lower fuel tank
It opens, consumes lower fuel tank oil transportation by 45 pairs of the check valve in small fuel tank 8, forward and backward group of fuel tank is defeated to gravity between small fuel tank 8
Oil still uses motive power pipeline road, and since fuel oil is not passed through oil transfer pump 2, the oil transfer pump 2 with high fluid resistance is not
Gravity oil transportation can be had an impact.Thus while power fuel transfer system and gravity fuel transfer system share pipeline road and attachment, but
It will not interfere between each other.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it
It is interior.
