Guide vane actuating mechanism of cylindrical centrifugal compressor

A driving mechanism is connected with an inlet side end cover, a driving gear of a transmission mechanism is connected with the driving mechanism, a gear ring is meshed with the driving gear, a guide vane is connected with a guide vane gear, and the guide vane gear is meshed with the gear ring. The driving mechanism sequentially transmits power to a driving gear and a gear ring of the transmission mechanism and a guide vane gear on the guide vane mechanism to further drive guide vanes to rotate, the power transmission structure can effectively overcome frictional resistance generated by high pressure difference, prevents high-pressure gas from leaking, and improves safety and reliability of the compressor. The guide vane executing mechanism is only installed on the inlet side end cover, the structures and installation of other components of the compressor are not affected, and therefore the guide vane executing mechanism has high applicability and can be widely applied to various cylindrical centrifugal compr
