Water vapor compressor shafting structure, water vapor compressor and air conditioner

Abstract

The application discloses a water vapor compressor shaft system structure, a water vapor compressor and an air conditioner, and comprises a motor, both ends of the motor outwardly extend a rotating shaft, the end of the rotating shaft is provided with an impeller, the side of the rotating shaft close to the motor is provided with a bearing, the bearing is provided with a gas supply sealing comb tooth; the inside of the side of the rotating shaft close to the motor is provided with a hollow section; the gas supply sealing comb tooth and the bearing are provided with a communicating air inlet pipeline, and the air inlet pipeline communicates with the hollow section; the side of the hollow section away from the motor is sequentially provided with a first gas outlet and a second gas outlet, and the first gas outlet and the second gas outlet both radially penetrate the rotating shaft and the bearing. The water vapor compressor shaft system structure of the application is provided with a hollow section, an air inlet pipeline, a first gas outlet and a second gas outlet, so that a large amount of heat generated by the shaft system structure can be promptly dissipated when the shaft system structure rotates at a high speed, the reliability of the shaft system structure is improved, and the situation that the temperature is too high to cause the deformation and damage of the whole shaft system structure is avoided.
