Embodiment Construction

[0019] Embodiments of the present invention are given below in conjunction with the accompanying drawings, and the working principle of the aero-engine reverse push door switch movement endurance test device of the present invention will be further described through the embodiments.

[0020] The aero-engine anti-push door switch motion endurance test device of this embodiment has a structure such as figure 1 , figure 2 and image 3 As shown, it is composed of a reverse push door switch motion control hydraulic system and a reverse push door switch motion control measurement and display system. The reverse push door switch movement control hydraulic system is a set of self-closed hydraulic system, such as figure 1 shown. The plunger type pressurized oil pump 2 whose inlet is connected to the hydraulic oil tank 1 is driven by the motor 3 to pressurize the hydraulic oil and output it, and then enters the one-way valve 4 . The function of the check valve is to prevent the rev...

Abstract

The invention discloses an aeroengine reverse push door switch motion endurance test device which comprises a reverse push door switch motion control hydraulic system and a reverse push door switch motion control measurement display system. The hydraulic system comprises a hydraulic oil tank, hydraulic actuators which push a reverse push door to open and close, a pressurization oil pump, a check valve, an oil pressure control valve which is arranged on an oil pipeline and a return pipeline, and a switch control valve which controls opening and closing of the reverse push door, wherein the pressurization oil pump and the check valve are arranged on the oil pipeline. The control measurement display system comprises a detection circuit which detects the state of a reverse push door lock, a detection circuit which detects the state of the switch control valve, a detection circuit which detects the state of the position of the reverse push door, a reverse push door opening timing circuit and a reverse push door closing timing circuit. The test device provided by the invention has the advantages of low manufacturing cost, reasonable work logic design, good reliability, clear operation display and the like.

Description

technical field [0001] The invention belongs to the technical field of component system reliability tests in the development and production of aero-engines, and in particular relates to a special device for carrying out endurance tests on the reverse thrust door switch movement in the aero-engine reverse thrust system. Background technique [0002] As we all know, the development and production of aero-engines is a jewel in the crown of the industrial manufacturing field. The design and manufacture level of aero-engine represents the top level of a country's industrial manufacturing technology. At present, only the United States, Britain, Russia, France and my country have the ability to independently develop aero-engines in the world. Relatively speaking, there is still a big gap between my country's aero-engine development level and the world's advanced level. The development of aero-engines involves all aspects of machinery, electronics, optics, information science, mat...
