Abstract

The invention discloses a compressor inlet guide vane adjustment mechanism and a control method thereof, which are suitable for the testing field of a centrifugal compressor of a compressed air energy storage system, and include pressure sleeves, rotating handles, set screws, fixing bolts and uniformly arranged circumferentially. Multiple inlet guide vane blades on the inlet guide vane cylinder can manually adjust the installation angle of the inlet guide vane. The main advantage of the present invention is that the inlet guide vane adjustment mechanism is manually adjusted, without complicated actuators and transmission linkages, etc., which can effectively reduce the complexity of the device; the inlet guide vane adjustment mechanism is provided with dials, metal pointers, etc., It can avoid control errors caused by pneumatic / electric actuators and improve the accuracy of compressor test results.

Description

technical field [0001] The invention belongs to the technical field of compressed air energy storage compressor testing, and relates to an inlet guide vane adjustment mechanism, in particular to a compressor inlet guide vane adjustment mechanism and a control method thereof, which can effectively reduce the complexity of the actuator and avoid pneumatic / The control error brought by the electric actuator improves the accuracy of the compressor test results. Background technique [0002] Compressed air energy storage technology is considered to be one of the most potential large-scale physical energy storage technologies. The compressors used in the system are usually centrifugal compressors. It is necessary to carry out experiments and tests on the aerodynamic and mechanical performance of the compressors to understand its internal flow. Coupling law with heat transfer, so as to meet the needs of high-efficiency and wide-ranging working conditions of compressed air energy st...
