Beschreibung
Zusammenfassung:	The invention discloses a screw compressor sealing structure and a sealing method, and belongs to the technical field of compressors, the sealing structure comprises a compressor shell, a rotor, a shaft sealing assembly and a sealing pressure reduction assembly, the rotor is supported in the compressor shell through a bearing, the shaft sealing assembly is located in the compressor shell, and the sealing pressure reduction assembly is located in the compressor shell. The shaft sealing assembly comprises a front sealing part and a main sealing part which are sequentially arranged on the outer side of the rotor in a sleeving mode. The sealing pressure reduction assembly is arranged on the outer side of the connecting position of the front sealing part and the main sealing part in a sealing and surrounding mode. The sealing structure is applied to the sealing method, and sealing of the shaft end of the screw compressor is achieved. The sealing pressure reduction assembly surrounds the outer side of the main seal
