Axial force balance device used for performance testing of axial-flow gas compressor

Abstract

The invention relates to an axial force balance regulation and control device used for performance testing of an axial-flow gas compressor. The axial force balance regulation and control device is designed for regulating and controlling the axial force of a test part rotor during test running of an aero-engine gas compressor component. The axial force balance regulation and control device comprises the compressor 1, a gas storage tank 2, a dryer 4, a pressure regulating valve 5, a solenoid valve 6, a testing unit 7, a test part balance chamber 8 and relevant pipes. The axial force balance regulation and control device is designed into an independent system. The device pipes can be flexibly arranged according to the actual working conditions. In the design process, the axial force balance regulation and control device is required to achieve continuous adjustability of variable working conditions, output stable and clean dry compressed gas and have the functions of rapidly and accuratelyadjusting and rapidly relieving pressure. After the design is completed, during the testing process of the gas compressor component, the axial force of the gas compressor component rotor is effectively balanced, the running state of the rotor is greatly improved during the running process of the test part, the testing risk is lowered, and the testing working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of aero-engine compressor tests, and focuses on the design of an axial force balance control mode in the process of the compressor test. Background technique [0002] In recent years, with the vigorous development of the domestic aviation industry, the development of advanced types of aero-engines has also entered the engineering stage. As one of the key components of aero-engines, the compressor is complex in design and difficult to develop. Therefore, the test and verification work is very important. Its design optimization and engineering application of serial installation of the whole machine are particularly important. [0003] At present, when most compressor testers are tested, the axial force balance mainly depends on the bearing of the test piece. The axial force that the test piece bearing can withstand is limited, and it is only suitable for the test requirements of the conventional compressor test piece; ...

Problems solved by technology

The axial force that the test piece bearing can withstand is limited, and it is only suitable for the test requirements of the conventional compressor test piece; for the high load, high power multi-stage high total pressure ratio compressor test piece, the shaft during operation The axial force load is too large, and the bearing of the test piece is difficult to bear completely (even if it is controlled by inlet throttling, it cannot meet the requirements), so it needs to be balanced by other devices or systems
