| description | The utility model relates to the technical field of ultralow-temperature magnetic levitation motors, in particular to an isolation sealing structure of an ultralow-temperature high-speed magnetic levitation turbine expansion motor, which comprises motors, a labyrinth sealing part and an air sealing cover, the labyrinth sealing part is positioned between the motors, and a certain gap is reserved between the labyrinth sealing part and a motor shaft to prevent dynamic and static friction; a high-pressure ultralow-temperature refrigerant at the turbine end leaks to the motor side through a gap between the labyrinth seal part and the shaft, and when the ultralow-temperature refrigerant leaks to the middle of the labyrinth seal part, the ultralow-temperature refrigerant is mixed with normal-temperature refrigerant gas and then continues to leak to the motor side. The temperature of the mixed gas leaked to the motor and the leakage amount of the ultralow-temperature refrigerant can be effectively adjusted by changin |
