Filling system for fuel tank of aircraft

Abstract

The invention provides an aircraft oil tank filling system in order to solve the technical problems that an existing aircraft filling system is single in function, an oil liquid detector in the system cannot detect oil liquid in an oil tank, oil liquid filling is time-consuming and labor-consuming, and the labor cost can be additionally increased. Comprising a gas pressure supply module, a new oil filling module, an old oil recycling module and a cleaning and flushing module. The gas pressure supply module is respectively connected with the fresh oil filling module, the old oil recovery module and the cleaning and flushing module, and is used for providing vacuum degree or pressurization for the fresh oil filling module, the old oil recovery module and the cleaning and flushing module; the new oil filling module is used for filling new oil into an aircraft oil tank; the old oil recovery module is connected with the cleaning and flushing module and is used for recovering waste oil in an aircraft oil tank and recovering recoverable cleaning oil or recoverable flushing oil in the aircraft oil tank to the cleaning and flushing module; and the cleaning and flushing module is used for filling cleaning oil or flushing oil into an aircraft oil tank.

Description

technical field [0001] The invention belongs to a fuel tank filling system, in particular to an aircraft fuel tank filling system. Background technique [0002] The existing aircraft filling system mainly includes filter separator, low liquid level control valve, high liquid level alarm, tank body, refueling pump, refueling reel, pipeline, valve, flow meter, oil liquid detector and filling Control System. Although the existing aircraft filling system has good flexibility, it has a single function. In addition, the oil detector in the aircraft filling system is only for the detection of newly injected oil, and cannot detect the oil in the fuel tank. However, after a long period of use, the fuel tank will accumulate a large amount of water and dirt, and the oil in the fuel tank needs to be specially inspected and cleaned before filling, which is not only time-consuming and laborious, but also increases labor costs. Especially for harmful media, it also increases the risk of...
