Axial force balance adjusting mechanism and method for magnetic suspension compressor

The invention discloses a magnetic suspension compressor axial force balance adjusting mechanism and method, the adjusting mechanism comprises a sealing ring connected to the periphery of a rotating shaft in a sleeving mode, the sealing ring is of a segmented structure and is divided into a plurality of sealing ring segments in the circumferential direction of the rotating shaft, and sealing teeth are arranged on the inner walls of the sealing ring segments; a connector sealing structure is arranged between the ends of every two adjacent sealing ring sections, the ends of the sealing ring sections are sealed through the connector sealing structures, the sealing ring sections are matched in a sealed mode to jointly form a continuous sealing structure on the periphery of the rotating shaft, and the sealing ring sections are connected with a driving mechanism used for driving the sealing ring sections to move in the radial direction of the rotating shaft. Through segmented design of the sealing ring, the sealing
