Abstract

The invention discloses a turbine compressor test system. The turbine compressor test system is characterized in that rotation output of a motor is driven to a turbine compressor main shaft of a turbine compressor through a transmission case and a torque sensor so as to form a test main engine, an air inlet disturbance unit, an exhaust disturbance unit, an airflow actuating device and a measure and control unit are respectively arranged aiming at the test main engine. The turbine compressor test system provided by the invention can test properties of the turbine compressor under various working conditions such as different air inlet condition saltations, air inlet distortion and exhaust conditional mutation, simulate the excitation of airflow to blades under different work conditions through an experimental method, and measure the parameters including stress and vibration frequency of the blades under situations with different excitation of airflow.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a turbo-compressor testing system and testing method. Background technique [0002] Turbocompressor is the core equipment in important industrial fields such as petrochemical, metallurgy and coal chemical industry, and its performance directly affects the performance and reliability of these large devices. Traditional turbocompressor test systems usually aim at a certain stable working condition, and test parameters such as flow rate, power, suction and discharge pressure, and temperature of the turbocompressor under this working condition on a standard turbocompressor test platform, and These parameters serve as the basis for evaluating and designing compressors. [0003] With the change of crude oil quality and the application of more and more new processes, the process parameters of compressors in the refining and chemical industry have gradually changed, whic...
