Engine fuel nozzle testing device

Abstract

The invention discloses an engine fuel nozzle testing device, which comprises a hydraulic system and an electrical control system. The hydraulic system comprises a pressure supply system (1), a nozzle test system (2), an air draft system (3) and an air system (4); and the electrical control system comprises a data acquisition system (5) and a computer system (6). According to the device, the sealing, pressure, flow and angle test of an engine fuel nozzle can be completed, the device integration is high, and the economic applicability is high; the tester has online detection and full-automatic test functions, test data are automatically stored, test results are convenient to output, and control software adapts to setting changes of parameter adjustment and is easy to improve; the equipment is good in stability, convenient to maintain and operate, simple in product installation and test operation, and convenient to disassemble and assemble instruments, filters and the like and clean an oil tank.

Description

technical field [0001] The invention relates to the technical field of aerospace engine fuel nozzle testing, in particular to an engine fuel nozzle testing device. Background technique [0002] The fuel nozzle is the core key component of the aero-engine, its function is to atomize or vaporize the fuel, accelerate the formation of the mixture, ensure stable combustion and improve combustion efficiency, so during the overhaul process of the aero-engine, the inspection and test of the fuel nozzle is the most important important. [0003] The internal working conditions of the combustion chamber of the aero-engine are very harsh, and the fuel nozzles work in a high-temperature and high-pressure environment for a long time, and they often have failures such as ablation, clogging, and flow exceeding the limit. With the rapid increase of working hours and working cycles of modern airline engines, the maintenance workload of fuel nozzles is continuously increasing. higher require...

Problems solved by technology

[0004] At present, in the field of aerospace, the test benches for engine fuel nozzle systems are all self-made, and foreign countries have imposed a technical blockade on us. Only professional fuel injector manufacturers can have such test benches, and they are politically and technically unreliable. Due to the blockade, it cannot be purchased in the market, so it can only be designed, developed and manufactured by itself. There has been no good test equipment for aviation kerosene spray angle test.

[0005] A utility model with the patent number CN207019883U discloses a fuel single nozzle spray angle test device, which can only test the spray angle of the fuel nozzle, which is relatively simple and not very practical
