Abstract
An integrated gas compressor is disclosed herein. The integrated gas compressor includes an integrated motor with a stator, centrifugal impellers, and a shaft assembly with a rotor and conical transition. The integrated motor can produce an electromotive force that is imparted by the stator to rotate the rotor and components coupled to the rotor, such as the conical transition and the centrifugal impellers. At least one of the rotor and conical transition have a cavity.
Claims13
An integrated gas compressor, the integrated gas compressor comprising:
- a housing;
- a plurality of centrifugal impellers positioned within the housing;
- an integrated motor positioned within the housing having
- a cylindrical stator, and
- a cylindrical rotor positioned inward and adjacent to the cylindrical stator;
- and
- a conical transition extending from the cylindrical rotor to the plurality of centrifugal impellers, at least one of the conical transition and the cylindrical rotor having a cavity.
A conical transition for an integrated gas compressor the conical transition comprising:
- a conical transition front end;
- a conical transition back end located opposite of the conical transition front end, the conical transition back end radially smaller than the conical transition front end;
- an annular middle step located between the conical transition front end and the conical transition back end;
- and
- a conical transition cavity extending from the conical transition front end to the conical transition back end, the conical transition cavity having a toriconical shape.
A rotor for an integrated gas compressor, the rotor comprising:
- a rotor front end;
- a rotor back end located opposite the rotor front end;
- and
- a rotor cavity located adjacent to the rotor back end and having a conical shape, the rotor cavity radially larger proximate the rotor back end than away from the rotor back end.
