Embodiment Construction

[0017] An oil seal control device for an aviation turbofan engine in an off-machine state such as Figure 1 ~ Figure 3 As shown, universal wheels 1 are installed at the bottom of the cabinet to facilitate ground movement. A control circuit board 3 is arranged in the upper equipment compartment of the cabinet, and a main control computer 2 is arranged on the upper floor of the lower equipment compartment of the cabinet, and the main control computer 2 is the control center of the whole oil seal control device. The lower floor of the lower equipment compartment of the casing is a stabilized power supply 4, which is used to supply power to the control circuit board 3 and the main control computer 2. The front portion of the casing is a control panel cabin, and the cabin is the operation panel 6 of the oil seal control device, and the operation panel 6 is used for operation control of the engine oil seal. The rear part of the casing is an interface equipment compartment, and the ...

Abstract

The invention discloses an oil seal control device of an aircraft turbofan engine under deplaning state. The device can realize 'false start' of the engine under the deplaning state (the deplaning state means the state of the engine state when the engine breaks away the control of the plane and works independently), thus driving an engine rotor to rotate and injecting oil-sealing oil fluid into the internal surface of an engine fuel system accessory and the internal surface of a turbo-starter fuel system accessory for oil sealing. The device includes a case, a signal acquisition system, an interface circuit system, an A / D converting system, a main control computer, a power supply system and a display and operating system. The device comprehensively utilizes the computer control technology, and the technologies of virtual instrumentation, signal testing and treatment and the like, firstly realizes the oil sealing control of the engine under the deplaning state and meets long-term oil sealing requirement of the aircraft turbofan engine.

Description

technical field [0001] The invention relates to an oil seal control device of an aircraft engine, in particular to an oil seal control device of an aircraft turbofan engine in an off-machine state. Background technique [0002] It is a very important task in the process of aviation maintenance to ensure that the aero-engine is in good working condition. [0003] The aviation turbofan engine maintenance process regulations stipulate: "When the engine is exhausted and needs to be returned to the factory for repair, the internal oil seal must be carried out. If the oil-sealed engine has been stored for more than three months, it must be unsealed and re-sealed." . Therefore, the engine oil seal equipment is one of the indispensable special equipment in the aircraft maintenance and support work, and it is an important ground equipment to ensure the normal operation of the engine and flight safety. [0004] The normal oil seal of an aviation turbofan engine is carried out on the...
