Description

Technical Field

[0001] The utility model relates to the technical field of aircraft fuel water contamination detection, and more specifically, to an aircraft fuel water contamination detection device. Background Art

[0002] As a vital component of the aircraft, the fuel system must be able to store fuel that meets the aircraft's flight time and range requirements, and continuously and effectively provide fuel that meets the engine's usage needs in a prescribed order on the ground and in all flight attitudes. Therefore, the cleanliness of the aircraft's fuel system will affect the engine's operating performance and service life, and directly endanger the safety of aircraft use.

[0003] Before the flight is completed or before refueling, the aircraft fuel needs to be sampled and tested. The existing testing device uses a simple glass bottle structure. After sampling, the staff needs to shake the glass bottle based on their own experience to observe the sediment in the aircraft fuel. If there is a lot of sediment, the aircraft fuel after testing needs to be poured out, and then continue to drain the fuel and continue testing. This process can only perform simple testing, in which microorganisms are not easily observed by the naked eye. The harmful effects of microorganisms on fuel performance, fuel tank structure, oil pump / oil filter and non-metallic materials also need to be tested separately. The process is cumbersome and time-consuming. Utility Model Content
