Abstract

The invention relates to the technical field of motors, in particular to a sealing structure for a magnetic levitation motor and the magnetic levitation motor. The sealing structure for the magnetic levitation motor includes a rotating shaft; On the rotating shaft and between the rotating shaft and the outer cover, there is a first gap between the sealing member and the rotating shaft; a first gap communicating with the first gap is opened on the sealing member A through hole and a second through hole, the first through hole communicates with the nitrogen gas source, the second through hole is used for exhaust, and the first through hole is away from the magnetic levitation motor for sealing relative to the second through hole structure of the rotor. The invention can ensure the protection of the motor while reducing the use of nitrogen and saving costs.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a sealing structure for a magnetic levitation motor and the magnetic levitation motor. Background technique [0002] Due to the gap between the impeller and the back plate of the magnetic levitation motor, part of the gas medium in the gas entering the volute from the air inlet will go around behind the impeller and leak into the interior of the motor through the gap between the shaft, sealing ring and thrust disc, thus Corrosion motor. [0003] The existing sealing technology is to directly space a plurality of holes on the back plate of the volute along the circumference of the back plate, and pass high-pressure nitrogen gas (higher than the pressure at the outlet of the volute) into the holes, and the nitrogen acts as a positive pressure. The role of blocking the gas in the volute. But this will require high nitrogen pressure and flow rate. In the case of long-term operation,...
