Abstract
A compressor or pump stage is provided. The compressor or pump stage at least comprising a central shaft (8) and one rotor (3), where the axis of rotation of the rotor (3) is the central shaft (8) and where the rotor comprises a number, n, of rows of impellers (5) arranged at an outer perimeter of the rotor with an axial distance between neighbouring rows of impellers (5), where n={2, 3, 4...}.
Claims21
A compressor or pump stage comprising:
- a central shaft and one rotor, where the axis of rotation of the rotor is the central shaft and where the rotor comprises a number, n, of rows of impellers arranged at an outer perimeter of the rotor with an axial distance between neighbouring rows of impellers, where n={2, 3, 4...}.
A compressor or pump arrangement at least comprising a number l1, l2, l3, l4,... lt of compressor or pump stages arranged axially adjacent with each other where each stage at least comprises a central shaft and one rotor where the axis of rotation of each rotor is the associated central shaft and where each rotor at least is provided with a number n≥2 rows of impellers arranged at an outer perimeter of its associated rotor with an axial distance between neighbouring rows of impellers.
A multidimensional scalable compressor and pump system at least comprising:
- a number l1, l2, l3,l4,...lt of compressor or pump stages arranged axially adjacent with each other where each stage at least comprises a central shaft and one rotor where the axis of rotation of each rotor is the associated central shaft;
- a number of compressor or pump stages arranged radially adjacent with each other
- where a first inner stage at least comprises a first inner central shaft and one first inner rotor where the axis of rotation of the first inner rotor is the first inner central shaft,
- a second outboard stage arranged radially outside of the first inner stage comprising a second outer rotor and where the axis of rotation of the second outer rotor is the first inner central shaft, and
- optionally a third outboard stage arranged radially outside of the second outer stage comprising a third outer rotor and where the axis of rotation of the third outer rotor is the first inner central shaft, and
- where each rotor at least is provided with one or more rows of impellers with an axial distance between neighbouring rows of impellers.
