The invention discloses a high-temperature fuel test bed for an aircraft hydraulic element. The high-temperature fuel test bed comprises a fuel loop, a heat-transfer oil loop and a nitrogen protecting loop, wherein the fuel loop is used for providing a continuous and adjustable hydraulic source to a tested product; the heat-transfer oil loop is used for indirectly heating; the nitrogen protecting loop is used for isolating oxygen in the fuel loop; the fuel loop comprises an oil supply loop and an oil return loop which are interconnected; the heat-transfer oil loop is connected with the oil return loop; and the nitrogen protecting loop is connected with the oil supply loop. The high-temperature fuel test bed for the aircraft hydraulic element has the advantages that the continuous and adjustable hydraulic source is provided for the tested product, the heating power is lower, the efficiency is high, and the safety is relatively ensured; and moreover, the high-temperature fuel test bed for the aircraft hydraulic element is high in working efficiency, and long in service life.
Description
technical field [0001] The invention relates to a testing device for aviation hydraulic components, in particular to a high-temperature fuel test bench for aviation hydraulic components. Background technique [0002] When conducting high-temperature performance tests on components such as aircraft electro-hydraulic servo valves, steering gear, fuel cross-linking valves, APU shut-off valves, and fuel shut-off valves, can it reliably provide fuel at a higher temperature and pressure to the tested product? become the key to the success of the experiment. However, because the medium used in the test bench is flammable and explosive fuel, and it is in a high-temperature state, the safety factor of the test benches currently on the market is not high, so it is dangerous and prone to accidents, and accidents caused by accidents The consequences are disastrous, so the development of a safe test bench is urgent.
