Based on the technical scheme, the system mainly comprises a fuel oil supply system, a pressurization system, a temperature measurement control system, a product driving system, a lubricating oil supply system, control management software and an environmental test box. The system overcomes the problem that the traditional test bed has low compatibility with test technical indexes, has wide flow, pressure and temperature ranges, and can provide accurate control measurement of pressure, flow, rotating speed, ambient temperature and medium temperature for different types of test pieces.
For the present invention, the fuel supply system comprises a closed large-capacity main fuel tank 1 and a sealed pressure-resistant fuel tank 7. The two can be used separately or work simultaneously according to different test technical conditions. When the inlet flow of the test piece 15 is large or the inlet pressure is large and the inlet oil absorption of the test piece 15 is not unnecessarily increased or decreased, the sealed large-capacity main fuel tank is used for independently working; when the inlet (i.e. fuel inlet) of the test piece 15 has low pressure and small flow, the sealed pressure-resistant oil tank 7 is used for independent work; when the inlet oil suction of the test piece 15 is increased or decreased unnecessarily, the test piece and the test piece work simultaneously, and the sealed pressure-resistant oil tank 7 is a large-volume low-pressure accumulator.

For the invention, the pressurizing system mainly comprises a gear pressurizing pump 5, a plunger pressurizing pump 4, a nitrogen pressurizing device 8 and various measuring sensors at the inlet and the outlet of the test piece 15. The three supercharging devices are switched according to different test technical conditions. When the inlet pressure of the test piece 15 is small and the flow is large, the gear booster pump 5 and the corresponding pipeline thereof are controlled to work; when the inlet pressure of the test piece 15 is large and the flow rate is small, the plunger booster pump 4 and the corresponding pipeline thereof are controlled to work; and when the inlet pressure of the test piece 15 is small, the flow is small or the inlet flow fluctuation is large, controlling the nitrogen pressurizing device 8 and the corresponding pipeline to work.

When the sealed large-capacity main fuel tank 1 is used for supplying fuel, the heating tank 20 and the external circulating water supply device 24 are used for controlling the temperature of a fuel medium, the fuel medium is enabled to circularly flow between the main fuel tank 1 and the heating tank 20 through the gear pump 22, the heating tank 20 heats the oil temperature, the external circulating cooling water is properly cooled through the first heat exchanger 23 between the heating tank 20 and the main fuel tank 1, the temperature of the fuel medium is measured through the fourth temperature sensor 24, and signals are acquired to the control system for PID control. When the sealed pressure-resistant fuel tank 7 is used, a low-power tube wall heating device (i.e., a tube wall heater) 11 is used for temperature control because of a small fuel medium capacity. When the ambient temperature is low, the temperature of the main fuel tank 1 flows to the front of the test piece 15, heat loss in a pipeline may exist, the pipe wall heating device (namely, the pipe wall heater) 1 is used for auxiliary heating, and the first temperature sensor 14 in front of the test piece is used for collecting temperature signals.

Meanwhile, the lubricating oil supply system 28 provides lubrication and cooling for the product driving system, and the cooling is mainly completed by connecting the second heat exchanger 29 in the pipeline to the external circulating water.
It should be noted that, when the test piece 15 in the test process needs to provide the ambient temperature, the test piece may be placed in an explosion-proof environmental test chamber, and the pipeline is connected to the test piece through a flange hole of the environmental test chamber wall. The explosion-proof environmental test box is used for providing a high-temperature or low-temperature environment required by the working condition of the test piece.
The invention provides a working state comprehensive environment test system for an aviation fuel test piece. The invention mainly comprises a pressurization system, a temperature measurement control system, a lubricating oil supply system, a product driving system, a fuel oil supply system (namely an oil source system) and an environmental test box, can realize the pressure supply of the inlet of a test piece, control the rotating speed of the test piece, and can control the environmental temperature and control and measure the temperature of an oil medium, the pressure of an outlet and the flow of the oil medium for the test piece.
Compared with the traditional fuel oil test equipment, the test equipment can meet the requirements of different types of test pieces and different technical indexes, can realize multiple purposes, and has wide coverage for aviation fuel oil test pieces in different stages and types.
In order to more clearly understand the technical solution of the present invention, the following describes the working principle of the present invention.
According to the invention, when the inlet flow of the test piece 15 is large in the test technical conditions, the selection is carried out through control system software, the system controls the main fuel tank 1 to work, the first cut-off valve 2 is opened, and the second cut-off valve 34 is closed. The first three-way change-over valve 3 controls the fuel to flow to the gear booster pump 5, the gear booster pump 5 works, and the second three-way change-over valve 6 closes the inlet of the sealed pressure-resistant oil tank 7 and enters the fuel inlet of the test piece 15 through the fuel filter 12. The second pneumatic pressure regulating valve 10 is used for controlling the flow of the fuel inlet bypass circuit of the test piece 15 back to the main fuel tank 1, and thus the fuel inlet pressure of the test piece 15 is controlled.
A first pressure sensor 13 and a first temperature sensor 14 are arranged in front of a fuel inlet of the test piece 15 and used for monitoring and measuring the pressure and the temperature at the fuel inlet of the test piece 15, and the opening degree of the second pneumatic pressure regulating valve 10 is adjusted through data collected by the first pressure sensor 13, so that the fuel inlet pressure PID control of the test piece 15 is carried out.
After the fuel flows out from the fuel outlet of the test piece 15, the fuel passes through the second temperature sensor 17, the second pressure sensor 18 and the flowmeter 19 to measure the corresponding data of the fuel outlet of the test piece 15. The third three-way switching valve 30 closes the passage of the sealed pressure-resistant fuel tank 7, and allows the fuel to flow back to the main fuel tank 1 through a third pneumatic pressure-regulating valve 33, wherein the third pneumatic pressure-regulating valve 33 is used for regulating the fuel outlet pressure of the test piece 15 by controlling the opening degree. The high-temperature energy storage 31 in the pipeline is mainly used for eliminating the pressure pulse phenomenon in the system caused by unstable flow velocity and the like.
When the inlet pressure is higher in the technical conditions of the test piece, the control system software is used for selecting, the system controls the three-way change-over valve 3 to enable fuel to flow from the main oil tank to the plunger pump 4, and the plunger booster pump 4 works. The rest of the operation is the same as above.
For the invention, when the fuel inlet pressure and the flow of the test piece 15 are small or the flow increases or decreases excessively in the test technical conditions, the system controls the sealed pressure-resistant oil tank 7 to work, the first cut-off valve 2 is closed, and the second cut-off valve 34 is opened. The air pressure input by the nitrogen supercharging device 8 is controlled by the first pneumatic pressure regulating valve 9, and the pressure entering the test piece 15 is controlled by the bypass second pneumatic pressure regulating valve 10. In this mode, the system controls the third three-way switching valve 30 so that the fuel flowing out of the outlet of the test piece 15 flows back to the sealed pressure-resistant fuel tank 7.
For the present invention, when the test technical condition requires the temperature of the fuel medium, the selection can be made by the control system software, the system controls the gear pump 22 to work, so that the fuel circulates between the main fuel tank 1 and the heating tank 20, the heating tank 20 works at the same time, the fuel medium in the heating tank 20 is heated, the external circulation cold water provided by the external circulation cold water providing device 24 is cooled by the first heat exchanger 23. The third temperature sensor 21 and the fourth temperature sensor 25 monitor and measure the temperature of the two oil solutions and transmit the temperature to the control system, the control system controls the working power of the heater 20, and simultaneously controls the water flow rate of the external circulating water entering the radiator (i.e. the first heat exchanger 23) by controlling the opening degree of the third pneumatic pressure regulating valve 32, thereby completing the PID control of the fuel temperature.
