Sealing System For Magnetic Levitating Centrifugal Compressor And Magnetic Levitating Centrifugal Compressor

Abstract: The present invention relates to a sealing system for magnetic levitating centrifugal 10 compressor, said magnetic levitating centrifugal compressor comprises a motor cavity and a motor shaft disposed within said motor cavity, an end of said motor shaft extends out from said motor cavity and is mounted with an impeller, said sealing system comprises: a seal which is sleeved on the outer side of said motor shaft and is disposed between said impeller and said motor cavity; a first magnet which is fixed at the outer 15 surface of said motor shaft; and a second magnet which is fixed at a side of said seal facing said motor shaft; wherein said first magnet and said second magnet form a radial repulsive force in the radial direction of said motor shaft, so that said seal can be levitated in relative to said motor shaft and move therewith. The present invention also proposes a magnetic levitating centrifugal compressor provided with said sealing 20 system, and a refrigeration system configured with said magnetic levitating centrifugal compressor.
