Abstract

The invention discloses a compressor inlet guide blade adjustment mechanism and a control method thereof, and relates to the field of compressed air energy storage system centrifugal compressor testing. The adjustment mechanism includes a pressing sleeve, a rotating handle, a set screw, a fixing bolt and a plurality of inlet guide blades arranged uniformly on an inlet guide blade drum body along the circumferential direction, and a mounting angle of the inlet guide blades can be adjusted manually. The adjustment mechanism has the main advantages that the inlet guide blade adjustment mechanismadopts manual adjustment without a complex execution mechanism and a transmission connecting rod mechanism and the like, and the complexity of a device is effectively reduced. The inlet guide blade adjustment mechanism is provided with a dial and metal pointers and the like, a control error brought by pneumatic / electric execution mechanisms, and the accuracy of a compressor testing result is improved.

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...
