Abstract

The invention discloses a booster compressor inlet guide vane adjusting device and method and belongs to the technical field of centrifugal compressors. The booster compressor inlet guide vane adjusting device comprises a drive handle, a drive handle transmission mechanism connected with the drive handle, an installing plate connected with the drive handle transmission mechanism, a drive handle transmission seal mechanism connected with the drive handle transmission mechanism, a guide vane rotating mechanism connected with a guide vane shell, an adjusting ring with one end connected with the drive handle transmission mechanism and the other end connected with the guide vane rotating mechanism, a guide vane rotating seal mechanism connected with the guide vane rotating mechanism, and a guide vane connected with the guide vane rotating mechanism. The booster compressor inlet guide vane adjusting device and method can effectively overcome friction resistance generated by the high-pressure difference, outward leakage of high-pressure gas is prevented, and safety and reliability of a compressor are improved.

Description

technical field [0001] The invention relates to the technical field of centrifugal compressors, in particular to a device and method for adjusting inlet guide vanes of booster compressors. Background technique [0002] The performance adjustment methods of centrifugal compressors include: inlet guide vane adjustment, inlet and outlet valve throttling, adjustable vane diffuser adjustment and variable speed adjustment, etc. Among them, the inlet guide vane adjustment is by changing the angle of the impeller inlet leading vane, so that Airflow generation pre-swirl adjustment method. Compared with other adjustment methods, the inlet guide vane adjustment has the advantages of small energy loss, wide adjustment range, online real-time adjustment, etc., and the use of servo actuators can also realize automatic adjustment. [0003] The transmission mechanism of the existing inlet guide vane adjustment device has the form of crank connecting rod, gear transmission, etc. The bearing...
