Abstract

A compressor module includes: a rotational driving machine having an output shaft which is rotationally driven around an axis; a compressor which is disposed so as to be adjacent to the rotational driving machine in an axial direction in which the axis extends; a base plate which supports the rotational driving machine and the compressor from below in a vertical direction; and a storage tank which is configured to store a lubricating oil used in the rotational driving machine and the compressor. The storage tank has a tubular tank main body that is provided on an outer side of the base plate in a width direction and extends in a direction including the axial direction.

Claims

1. A compressor module comprising:

a rotational driving machine having an output shaft which is rotationally driven around an axis;

a compressor which is arranged side by side in an axial direction in which the axis extends with respect to the rotational driving machine, and to which rotation of the output shaft is transmitted;

a base plate which supports the rotational driving machine and the compressor from below in a vertical direction, and is larger than the rotational driving machine and the compressor when viewed from above in the vertical direction; and

a storage tank which is configured to store a lubricating oil used in the rotational driving machine and the compressor,

wherein the storage tank has a tubular tank main body that is provided on an outer side of the base plate in a width direction intersecting with the axial direction and extends in a direction including the axial direction.

2. The compressor module according to claim 1,

wherein the tank main body extends from a position overlapping at least a part of the rotational driving machine to a position overlapping at least a part of the compressor when viewed in a direction orthogonal to the axial direction.

3. The compressor module according to claim 1, further comprising:

a drain piping which is configured to return the lubricating oil from the rotational driving machine or the compressor to the tank main body,

wherein the drain piping is connected to a side surface of the tank main body.

4. The compressor module according to claim 3,

wherein the drain piping is inclined so as to extend downward in the vertical direction and extend in the width direction toward the tank main body.

5. The compressor module according to claim 1,

wherein the base plate includes

a first beam portion which is provided with a space in the axial direction and extends in the width direction, and

a second beam portion which is provided with a space in the width direction and extends in the axial direction, and

wherein the tank main body is disposed on the outer side of the base plate and fixed to a side surface of the second beam portion, when viewed from above in the vertical direction.

6. The compressor module according to claim 1,

wherein a lubricating oil supply device that is configured to supply the lubricating oil to the rotational driving machine and the compressor is provided on the tank main body.

7. The compressor module according to claim 2, further comprising:

a drain piping which is configured to return the lubricating oil from the rotational driving machine or the compressor to the tank main body,

wherein the drain piping is connected to a side surface of the tank main body.

8. The compressor module according to claim 7,

wherein the drain piping is inclined so as to extend downward in the vertical direction and extend in the width direction toward the tank main body.

9. The compressor module according to claim 2,

wherein the base plate includes

a first beam portion which is provided with a space in the axial direction and extends in the width direction, and

a second beam portion which is provided with a space in the width direction and extends in the axial direction, and

wherein the tank main body is disposed on the outer side of the base plate and fixed to a side surface of the second beam portion, when viewed from above in the vertical direction.

10. The compressor module according to claim 3,

wherein the base plate includes

a first beam portion which is provided with a space in the axial direction and extends in the width direction, and

a second beam portion which is provided with a space in the width direction and extends in the axial direction, and

wherein the tank main body is disposed on the outer side of the base plate and fixed to a side surface of the second beam portion, when viewed from above in the vertical direction.

11. The compressor module according to claim 4,

wherein the base plate includes

a first beam portion which is provided with a space in the axial direction and extends in the width direction, and

a second beam portion which is provided with a space in the width direction and extends in the axial direction, and

wherein the tank main body is disposed on the outer side of the base plate and fixed to a side surface of the second beam portion, when viewed from above in the vertical direction.

12. The compressor module according to claim 7,

wherein the base plate includes

a first beam portion which is provided with a space in the axial direction and extends in the width direction, and

a second beam portion which is provided with a space in the width direction and extends in the axial direction, and

wherein the tank main body is disposed on the outer side of the base plate and fixed to a side surface of the second beam portion, when viewed from above in the vertical direction.

13. The compressor module according to claim 8,

wherein the base plate includes

a first beam portion which is provided with a space in the axial direction and extends in the width direction, and

a second beam portion which is provided with a space in the width direction and extends in the axial direction, and

wherein the tank main body is disposed on the outer side of the base plate and fixed to a side surface of the second beam portion, when viewed from above in the vertical direction.
