The invention discloses small-flow flow passage component liquid flow test bed equipment which is wide in measurement range and high in measurement and control precision. A pure water system is connected with a high-pressure water pipe in the process system to provide a deionized water test medium for the process system; a gas distribution system is connected with a process system to provide driving gas for a pneumatic valve in the process system and provide front-end test pressure for the process system; a measuring system is used for acquiring test data; a control system controls opening and closing of a process system valve; the process system comprises a high-pressure process gas module, a high-pressure pure water module and a process pipeline module; the high-pressure process gas module consists of a high-pressure air compressor and a high-pressure pressure container, the high-pressure air compressor is used for pressurizing air, and the high-pressure pressure container is used for storing high-pressure air; a high-pressure pure water module is composed of a high-pressure pressure container, a safety valve and a liquid level meter, the high-pressure pressure container stores a test medium of deionized water, the safety valve guarantees safe operation of the system, and the liquid level meter measures and displays the liquid level position in the container.
Description
technical field [0001] The invention relates to the technical field of rocket control, and in particular to a liquid flow test bench equipment for small flow passing parts, which is used to conduct liquid flow tests on parts of liquid rocket engines to verify their flow characteristics, flow resistance characteristics, flow characteristics, and flow characteristics. Performance parameters such as state performance. Background technique [0002] In the process of R&D, design and manufacturing of liquid rocket engines, to verify the correctness of the design and processing of thrust chamber products, valve products, venturi tubes and other parts and components of rocket engines. It is necessary to carry out liquid flow tests on engine components to verify performance parameters such as flow characteristics, flow resistance characteristics, and flow performance. There are many types of liquid flow tests, and the flow and pressure requirements are also different, and the parts ...
