Problems solved by technology

The ground test of traditional aero-engine components often requires multiple test equipment to conduct separate tests. The temperature of the test fuel is controlled by means of electric heating and circulating cooling water cooling simultaneously. Often the external circulating water is always on or the electric heating continues to work. Serious waste
[0003] The Chinese patent application number 201210003344.9 discloses a comprehensive test system for aviation fuel accessories. In this patent, the performance test of fuel servo / proportional valves and other products is mainly completed, and the temperature of the fuel medium is not adjusted at high temperature.

Embodiment Construction

[0022] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0023] to combine Figure 1-Figure 6 , a high-temperature fuel servo flow metering characteristic test system of this embodiment is composed of a fuel power source, a fuel test system and a hydraulic load simulation system.

[0024] figure 1 It is the schematic diagram of the fuel power source system. The fuel is extracted from the fuel tank 1 through the shut-off valve 2 by the fuel pump motor unit 3, and then enters the oil temperature adjustment system 8 through the filter 5 and the shut-off valve 6. Fine filtration, the finely filtered oil can be controlled by the pneumatic three-way valve 10 to enter the main oil circuit P0 or enter the fuel tank 1. At the same time, an overflow valve 4 is provided behind the outlet of the motor pump unit 3 to communicate with the fuel tank 1; the return oil T0 of the fuel test system can enter the oil ...

Abstract

The invention discloses a high-temperature fuel oil servo flow metering characteristic test system which comprises a fuel oil power source system used for providing supercharged fuel oil with adjustable temperature for a fuel oil test system; the fuel oil test system is provided with a fuel oil guide vane control device, a fuel oil distributor, a main fuel oil pump, a simulation fan guide vane actuating cylinder, a simulation gas compressor guide vane actuating cylinder and a simulation nozzle; and the load simulation system is used for providing loads for the simulation fan guide vane actuating cylinder and the simulation compressor guide vane actuating cylinder. The system has the functions of continuously adjustable inlet temperature of a main fuel pump, simulation of a fan guide vane actuator cylinder, simulation of a gas compressor guide vane actuator cylinder, simulation of a nozzle, fuel flow servo metering of main oil ports of all tested pieces, real-time monitoring of pressure / pressure difference and temperature and the like.

Description

technical field [0001] The invention belongs to the field of ground testing of an aero-engine fuel system, in particular to a high-temperature fuel servo flow metering characteristic test system. Background technique [0002] With the development of my country's aviation industry, in order to test the performance of aircraft and other equipment, it is necessary to conduct systematic ground tests on airborne equipment. The engine is the core power device of the aircraft, and its product performance is directly related to the flight performance of the aircraft. The ground test of traditional aero-engine components often requires multiple test equipment to conduct separate tests. The temperature of the test fuel is controlled by means of electric heating and circulating cooling water cooling simultaneously. Often the external circulating water is always on or the electric heating continues to work. Serious waste. [0003] The Chinese patent application number 201210003344.9 d...
