Embodiment 1

[0034] A high-pressure oil pump fire resistance test tool for an engine, including a burner 1, a high-pressure oil pump 2, a tool stand 3 and a standard joint 4, the burner 1 is arranged on one side of the high-pressure oil pump 2, and the high-pressure oil pump 2 is installed on the tool stand 3 for use It is used to simulate the assembly of the high-pressure oil pump and the high-pressure oil pump 2 on the engine. A high-pressure oil pipe 21, a fuel hose assembly 22, a fuel quantity control unit 26 and a temperature sensor 211 are installed on the high-pressure oil pump 2, a fuel damper 212 is installed on the fuel hose assembly 22, and a hollow bolt 28 is installed on the high-pressure oil pump 2 There is a Banjo joint assembly 27, the fuel rail return pipe 29 and the fuel injector return pipe 210 are communicated with the Banjo joint assembly 27, and the fuel hose assembly 22 is equipped with a pressure sensor 23 through a hollow bolt 24. Specifically, the oil pressure can...

Embodiment 2

[0040] A high-pressure oil pump fire-resistant test tooling for an engine. On the basis of Embodiment 1, the tooling stand 3 includes a mounting frame 36, a high-pressure oil pump mounting platform 35 and a mounting 37 are fixed on the mounting frame 36, and a rotating rod is mounted on the mounting 37 38. The high-pressure oil pump 2 is fixedly installed on the high-pressure oil pump installation platform 35, and the input end of the high-pressure oil pump 2 is connected to the rotating rod 38, and the other end of the rotating rod 38 is connected to the driving motor fixed on the tooling stand 3 through the transmission of the sprocket assembly 34.

Abstract

The invention discloses a fire resistance test tool for a high-pressure oil pump of an engine. The test tool comprises a combustor, the high-pressure oil pump, a tool rack and a standard connector, the combustor is arranged at one side of the high-pressure oil pump, and the high-pressure oil pump is installed on the tool rack and used for simulating assembly of the high-pressure oil pump on the engine; a high-pressure oil pipe, a fuel hose assembly, an oil quantity control unit and a temperature sensor are installed on the high-pressure oil pump, a fuel damper is installed on the fuel hose assembly, and a Banjo connector assembly is installed on the high-pressure oil pump through a hollow bolt. According to the scheme, the assembly state of the high-pressure oil pump on the engine can be simulated, the fire resistance test is simplified, a complex structure for performing the fire resistance test on the whole engine is replaced, the test cost of the whole engine is reduced, the assembly of parts is reduced, and the basic requirements of the fire resistance test are met.

Description

technical field [0001] The invention relates to the field of aviation, in particular to a fire-resistant test tool for an engine high-pressure oil pump. Background technique [0002] Aeroengines are the core components of aircraft in the general aviation field. In addition to meeting the performance requirements of the engine itself, it also needs to meet the fire protection requirements of civil aviation. That is: during normal operation of the engine, every external pipe, joint and other part that retains or conveys flammable liquids must be confirmed by the Civil Aviation Administration of China to be fire-resistant or fire-resistant. [0003] As the fuel supply part of the engine, the high-pressure oil pump must pass a specific fire test to verify the fire-resistant performance of the high-pressure oil pump, which shows that the design and configuration of the high-pressure oil pump can prevent fuel leakage from aggravating the fire in the event of a fire. Or the amount...
