Embodiment Construction
[0024] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.
[0025] This application is based on the existing pressure oil filling method combined with the real-time testing technology of the oil level of the lubricating oil tank and the quantitative / constant pressure ground refueling technology, so as to realize the lubricating oil filling of the engine lubricating oil tank under the working state of the ground idle, thereby reducing the engine maintenance time. Ensure the rapidity of the engine re-starting.
[0026] Such as figure 2 Shown is the system provided by this application that can realize oil tank refueling under the working state of an aeroengine, which mainly includes a oil tank 20, an aircraft cockpit oil level display device 30 for processing and analy...

The present application provides a system for filling lubricating oil in the working state of an aero-engine. The system includes: an oil tank arranged in the aero-engine, an oil level sensor is arranged in the oil tank, and the bottom of the oil tank A pressure refueling port is provided; an aircraft cockpit oil level display device connected to the oil level sensor, and the aircraft cockpit oil level display device calculates and displays the lubricating oil that needs to be filled according to the remaining lubricating oil in the lubricating oil tank measured by the oil level sensor Refueling amount; and the ground refueling device connected to the pressure refueling port, by adjusting and setting the refueling pressure and refueling amount of the ground refueling device to the lubricating oil tank, the refueling of lubricating oil is realized. The system provided by this application can realize the lubricating oil filling of the aeroengine in the idle working state, shorten the lubricating oil filling maintenance cycle, simplify the lubricating oil filling maintenance work, reduce the lubricating oil filling maintenance work cost, and improve the speed of the aircraft again. dispatch ability.
Description
technical field [0001] The application belongs to the technical field of aero-engine maintenance, and in particular relates to a system for filling lubricating oil in the working state of an aero-engine. Background technique [0002] Such as figure 1 As shown, the aero-engine oil tank 20 is used to store lubricating oil required for the lubrication system. The capacity of the oil tank 20 is usually determined by the endurance time of the engine 10, that is, the oil tank can satisfy the longest continuous operation of the engine after it is filled with lubricating oil. time demands. The filling of lubricating oil in the lubricating oil tank mainly includes two methods: gravity filling and pressure filling. The gravity refueling method is usually poured directly from the gravity refueling port 21 located on the upper part of the lubricating oil tank 20 , and the pressure refueling method uses ground refueling truck equipment to pressurize the lubricating oil into the lubrica...
