High-flow liquid medium combined supply system

Abstract

The invention belongs to the technical field of aircraft and airspace engine testing, and particularly relates to a high-flow liquid medium combined supply system. The system comprises a pressurization unit, a storage unit and a supply unit. The pressurization unit communicates with the storage unit and is used for carrying out pressurization on the storage unit. The storage unit is used for storing media. The storage unit and the supply unit communicate with each other to be used for providing the media for multiple terminals. According to the improvement of the high-flow liquid medium combined supply system, the supply unit is composed of two or more branched pipelines, the lengths of connecting pipelines between the branched pipelines are consistent, and the lengths of the branched pipelines are consistent. The system can carry out combined supply on the multiple terminals working at the same time, it is guaranteed that the flow and pressure of each terminal are stable when the multiple terminals work at the same time, and it is ensured that the working condition of each terminal can meet the requirement of the rated working condition.

Description

technical field [0001] The invention belongs to the technical field of aviation and aerospace engine tests, and in particular relates to a large-flow liquid medium combined supply system. Background technique [0002] At present, in the liquid fluid supply system, when multiple terminals at the end of the system need to be supplied at the same time, there are problems that the flow rates of multiple terminals are not uniform and the pressure is unstable. This problem will eventually cause differences in working conditions when multiple terminals work at the same time. Larger, and even some terminals cannot meet the rated working condition requirements. [0003] At present, when the existing supply system is supplying media to multiple identical equipment at the same time, the setting of the pipeline branch follows the equipment position setting, the pipeline setting length is not set to the same interval and branch length, and the pressure measurement is not set at the end o...

Problems solved by technology

During the working process of the existing supply system, its pressurization unit directly pressurizes the medium storage unit through the air source. During the working process of the terminal equipment, as the working conditions of the terminal equipment change, the pressurization system cannot adjust according to the terminal equipment. The working condition of the equipment automatically adjusts the supply pressure, which can only be adjusted by manually controlling the pneumatic valve of the booster unit
