Abstract

The invention discloses an aircraft test liquid level measurement and control system, belonging to the technical field of aircraft testing, comprising a liquid outlet pipe and a liquid return pipe installed on a pipeline to be tested, a liquid sight barrel connected with the liquid outlet pipe, and a liquid sight barrel The effusion bags are connected to each other. The outlet pipe is connected to the pipeline to be tested through a set of adjustment mechanisms for adjusting its angle and position. There are slide rails, and the slider at the bottom of the sight liquid barrel is slidably connected with the slide rail. The front of the sight liquid barrel is equipped with two sets of vertically corresponding sight mirrors, and the side of the sight liquid barrel is equipped with two sets of vertically corresponding capacitor liquid levels. Gauge, sight glass and capacitance level gauge are set alternately. The invention realizes the timely and accurate measurement and control of the liquid level under the two working conditions of filling and emptying of the pipeline to be tested, and has a wide range of applications. At the same time, a part of the refrigerant can be stored inside the effusion bag, which can slow down the filling. And the speed of the brine during the emptying process makes the whole process more stable.

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to an aircraft testing liquid level measurement and control system. Background technique [0002] In the process of aircraft testing, it is necessary to adjust the experimental environment, especially the refrigeration system. Various refrigerants are often used in the refrigeration system, especially low-temperature refrigerants. However, low-temperature refrigerants will condense in extremely low-temperature environments. Once the low-temperature refrigerant condenses, it will cause blockage of the pipeline and bring safety hazards to the refrigeration system. Therefore, it is necessary to observe the liquid level of the low-temperature refrigerant in the pipeline in real time to judge whether the low-temperature refrigerant in the pipeline is completely discharged. empty and full. [0003] Commonly used low-temperature refrigerants such as LM-8 glacial refrigerant will ...
