Problems solved by technology

[0005] Low efficiency: The test process on the ground is complicated. The detection of engine performance parameters usually requires multiple tests. There are many test personnel, high labor intensity, long test time, serious fuel consumption, low efficiency, and repetition caused by misjudgments and missed tests. Operation also consumes more service life of aviation hydraulic lines

Abstract

The invention provides an aviation hydraulic test system. The aviation hydraulic test system comprises an interface panel unit, a returned oil test unit, a dynamic pressure component unit, a static pressure test unit and a pump station unit. The interface panel unit is connected with the returned oil test unit, the dynamic pressure component unit and the static pressure test unit through pipelines and used for providing hydraulic test input, output and adjustment; the pump station unit is connected with the returned oil test unit, the dynamic pressure component unit and the static pressure test unit through pipelines and used for providing continuous fuel oil. The aviation hydraulic test system can reduce the labor cost to the greatest extent, high in accuracy and suitable for testing at various sites, moves conveniently and can measure various kinds of hydraulic pressure including static pressure, dynamic pressure and returned oil. The aviation hydraulic test system is convenient to use and easy to operate.

Description

technical field [0001] The invention relates to the field of aviation testing, in particular to an aviation hydraulic testing system. Background technique [0002] PTU hydraulic transmission and hydraulic motor are important hydraulic components in civil aviation aircraft, and occupy a pivotal position in the maintenance of civil aviation aircraft. The full name of PTU is power conversion unit, which is a coaxial hydraulic pump motor assembly. When the PTU control valve is opened, the motor receives the pressure from the hydraulic system to make the motor rotate; the hydraulic pump receives the oil supply from the hydraulic system tank and moves forward Edge flaps and slats provide back-up pressure; meanwhile case return oil cools and lubricates the motor and hydraulic pump. The kinetic energy of PTU is to use one hydraulic system to restore the work of another hydraulic system and improve the reliability of the hydraulic system. [0003] Due to the large driving power and...
