Beschreibung
Zusammenfassung:	The invention belongs to the technical field of gas turbine sealing, and particularly relates to a novel partition plate-perforated partition plate combined labyrinth seal structure which comprises a rotor shaft body and a combined labyrinth seal structure mounted on the rotor shaft body, and the combined labyrinth seal structure is a perforated partition plate preposed combined labyrinth seal structure. The combined labyrinth seal structure with the front perforated partition plates comprises a plurality of perforated partition plates and a plurality of partition plates, the perforated partition plates are arranged on the side close to the airflow inlet, and two partition plates are arranged between every two adjacent perforated partition plates, namely the perforated partition plates and the partition plates are arranged alternately. A partition plate labyrinth sealing structure in a traditional labyrinth sealing structure and a damping type sealing structure is subjected to composite structural improvement
