[0010] Hereinafter, an embodiment of the compressor module 100 according to the present disclosure will be described with reference to the accompanying drawings. However, the present disclosure is not limited to this embodiment.

[0011] (Compressor module configuration) As shown in Figures 1 to 4, the compressor module 100 includes a compressor 1, a rotary drive unit 2, a gas supply device 3, multiple cooling sections 4, an oil console device 5, a first support section 6, a second support section 7, a third support section 8, a fourth support section 9, and a drive support section 25.

[0012] (Compressor) The compressor 1 compresses gas as a working fluid. The compressor 1 has a rotating shaft 1a that rotates around an axis O. The rotating shaft 1a has a cylindrical shape centered on the axis O. The compressor 1 is capable of compressing gas (fluid) in stages. The compressor 1 of this embodiment has a plurality of compression sections 10, thereby enabling the compressor 1 to compress gas in stages. The compressor 1 of this embodiment is a geared compressor having, for example, eight compression sections 10. In the compressor 1, each compression section 10 has one impeller (not shown).

[0013] The compressor 1 of this embodiment further includes a gear casing 1b having a plurality of gears (not shown) therein. The gear casing 1b can be divided into upper and lower parts. The upper half of the gear casing 1b can be removed to view the internal gears. The gears can transmit the rotation of the rotating shaft 1a to a plurality of driven shafts (not shown). The driven shafts have compression sections 10 at both ends, respectively, and extend in the axial direction Da parallel to the rotating shaft 1a. The multiple gears set the rotation speeds of the multiple (four in this embodiment) driven shafts to be different from each other. The rotating shafts 1a extend so as to protrude outside the gear casing 1b.

[0014] In the following description, the direction in which the axis O of the rotating shaft 1a (described later) extends is referred to as the axial direction Da. There is one axial direction Da in the horizontal direction. The horizontal direction is the direction in which an imaginary plane perpendicular to the vertical direction Dv extends. One of the horizontal directions perpendicular to the axial direction Da is referred to as the width direction Dw.

[0015] The multiple compression sections 10 are disposed outside the gear casing 1b. The compressor 1 of this embodiment has, as the compression sections 10, a first compression section 11, a second compression section 12, a third compression section 13, a fourth compression section 14, a fifth compression section 15, a sixth compression section 16, a seventh compression section 17, and an eighth compression section 18.

[0016] The first compression section 11 compresses gas supplied from outside the compressor 1. Among the multiple compression sections 10, the first compression section 11 has the largest volumetric flow rate of gas to be compressed. The second compression section 12 compresses the gas compressed in the first compression section 11. The second compression section 12 is rotated by the same driven shaft as the first compression section 11. The volumetric flow rate of gas compressed in the second compression section 12 is smaller than that of the first compression section 11.

[0017] The third compression section 13 compresses the gas compressed in the second compression section 12. The third compression section 13 is rotated by a driven shaft different from those of the first compression section 11 and the second compression section 12. The volumetric flow rate of the gas compressed in the third compression section 13 is smaller than that of the second compression section 12. The fourth compression section 14 compresses the gas compressed in the third compression section 13. The fourth compression section 14 is rotated by the same driven shaft as the third compression section 13. The volumetric flow rate of the gas compressed in the fourth compression section 14 is smaller than that of the third compression section 13.

[0018] The fifth compression section 15 compresses the gas compressed in the fourth compression section 14. The fifth compression section 15 is rotated by a driven shaft different from those of the third compression section 13 and the fourth compression section 14. The volumetric flow rate of the gas compressed in the fifth compression section 15 is smaller than that of the fourth compression section 14. The sixth compression section 16 compresses the gas compressed in the fifth compression section 15. The sixth compression section 16 is rotated by the same driven shaft as the fifth compression section 15. The volumetric flow rate of the gas compressed in the sixth compression section 16 is smaller than that of the fifth compression section 15.

[0019] The seventh compression section 17 compresses the gas compressed in the sixth compression section 16. The seventh compression section 17 is rotated by a driven shaft different from those of the fifth compression section 15 and the sixth compression section 16. The volumetric flow rate of gas compressed in the seventh compression section 17 is smaller than that of the sixth compression section 16. The eighth compression section 18 compresses the gas compressed in the seventh compression section 17. The eighth compression section 18 is rotated by the same driven shaft as the seventh compression section 17. The volumetric flow rate of gas compressed in the eighth compression section 18 is smaller than that of the seventh compression section 17.

[0020] (Rotary drive) The rotary drive 2 is connected to the compressor 1. The rotary drive 2 drives the compressor 1. The rotary drive 2 has an output shaft 2a that is rotationally driven. The rotary drive 2 in this embodiment is, for example, an electric motor. The rotary drive 2 always rotates the output shaft 2a at a constant speed. The output shaft 2a is rotationally driven around an axis O. The output shaft 2a is cylindrical with the axis O as its center. The output shaft 2a is connected to the rotating shaft 1a. As a result, the rotation of the output shaft 2a is transmitted to the rotating shaft 1a. Note that the rotary drive 2 is not limited to a structure in which it is directly connected to the compressor 1, and may be a structure in which it is indirectly connected via a transmission or the like. The rotary drive 2 is arranged side by side with a gap in the axial direction Da relative to the compressor 1. In addition, the output shaft 2a of the rotary drive 2 is heavier than the rotating shaft 1a of the compressor 1 and has a relatively low rotation frequency, so that it is likely to cause excitation (resonance) due to a low-order vibration mode during operation.

[0021] (Gas supply equipment) The gas supplying device 3 is capable of supplying a seal gas to the compressor 1. The gas supplying device 3 is connected to the compressor 1 by a plurality of pipes 31. The gas supplying device 3 is disposed away from the compressor 1 in the width direction Dw. The gas supplying device 3 of this embodiment is a gas seal module (GSM: gas seal device). The gas supplying device 3 is capable of adjusting the pressure of the seal gas to be higher than the pressure inside in order to prevent the seal gas sent to a dry gas seal (not shown) disposed in the casing from flowing back in the dry gas seal.

[0022] (cooling section) The cooling sections 4 cool the gas compressed by the compressor 1. The cooling sections 4 are arranged between two compression sections 10, one at a time.

The drive support part 25 is arranged to be aligned with the first support part 6 in the axial direction Da. The drive support part 25 is formed so that the position of the output shaft 2a of the rotary drive machine 2 and the position of the rotation shaft 1a of the compressor 1 are arranged at the same position (level) in the vertical direction Dv. The drive support part 25 is formed as a gate-shaped base made of concrete having higher rigidity than the first support part 6 and the second support part 7, for example. The drive support part 25 is directly fixed to the foundation 200. The drive support part 25 is arranged independently of the first support part 6, the second support part 7, the third support part 8, and the fourth support part 9.

[0048] (Action and effect) In the compressor module 100 having the above configuration, the first support part 6 is fixed on the second support part 7 having a rigid frame structure. The first support part 6 constitutes a first unit A that can be transported with the compressor 1 and the gas supply device 3 fixed thereto. The second support part 7 constitutes a second unit B that can be transported with the first cooling part 41 and the second cooling part 42 fixed thereto. Therefore, the first cooling part 41 and the second cooling part 42 that are fixed and in a fixed position (unmovable state) can be placed at a specified installation position simply by transporting the second support part 7. Therefore, the installation work of the first cooling part 41 and the second cooling part 42 can be shortened. Similarly, the compressor 1 and the gas supply device 3 that are fixed and in a fixed position can be placed at the installation position of the compressor module 100 simply by transporting the first support part 6 and fixing it on the second support part 7. In particular, the compressor 1 and the gas supply device 3 are in a state where the piping 31 is already connected. Therefore, after arranging the compressor 1 and the gas supply equipment 3, there is no need to perform additional work of connecting the piping 31 between the compressor 1 and the gas supply equipment 3. This makes it possible to shorten the installation work of the compressor 1 and the gas supply equipment 3. As a result, it is possible to shorten the installation work of the compressor module 100.

[0049] Moreover, the gear casing 1b of the compressor 1 can be separated into an upper part and a lower part. Such a compressor 1 is fixed on a first support part 6 which is fixed on a second support part 7. Therefore, in the first support part 6, nothing is arranged above the compressor 1 in the vertical direction Dv. Therefore, the upper half of the gear casing 1b can be removed to maintain accessibility for maintenance.

[0050] Furthermore, the gas supply equipment 3 is fixed on the first support part 6 alongside the compressor 1. In the first support part 6, nothing is arranged above the gas supply equipment 3 in the vertical direction Dv. Therefore, the gas supply equipment 3 can be maintained independently of the compressor 1. There are cases where the gas supply equipment 3 is maintained while the compressor 1 is operating, and even in such cases, the maintainability of the gas supply equipment 3 can be ensured.

[0051] Furthermore, the first cooling section 41, which has the largest volume among the multiple cooling sections 4, is fixed to the second support section 7 together with the second cooling section 42. Therefore, the cooling section 4 which is heavier among the multiple cooling sections 4 is disposed below the compressor 1 in the vertical direction Dv. Therefore, even if the compressor 1 is disposed at a high position relative to the foundation 200, such as the first support section 6 on the second support section 7, the compressor 1 can be stably supported by the first cooling section 41 and the second cooling section 42, which are heavy objects.

[0052] Furthermore, the second support part 7 is fixed directly below the first support part 6 in the vertical direction Dv. This allows the first cooling part 41 and the second cooling part 42 to be positioned closer to the compressor 1. This allows the connection pipes such as the expansion joint 49 that connect the first cooling part 41 and the second cooling part 42 to the compressor 1 to be shortened.

[0053] Moreover, the first cooling section 41 is connected to the first compression section 11 and the second compression section 12, respectively, by an expansion joint 49. Similarly, the second cooling section 42 is connected to the second compression section 12 and the third compression section 13, respectively, by an expansion joint 49. Therefore, even if the positions of the first cooling section 41 or the second cooling section 42 and the compressor 1 are misaligned when the first support section 6 and the second support section 7 are fixed, the installation error between the compression section 10 and the cooling section 4 can be absorbed by the expansion joint 49.

[0054] Moreover, the second support section 7 has two pillar sections 75 at positions between the first cooling section 41 and the second cooling section 42 and overlapping with the compressor 1 when viewed from the axial direction Da. Therefore, the compressor 1 can be supported from below in the vertical direction Dv by the two pillar sections 75. As a result, the support rigidity in the vertical direction Dv for the compressor 1 can be increased compared to the case where the compressor 1 is supported only by the first upper frame body and the second upper frame body 7a.

[0055] In particular, in this embodiment, the first cross beam portion 62, the second upper cross beam portion 72, and the second lower cross beam portion 74 are also arranged at positions overlapping with the compressor 1 when viewed from the vertical direction Dv. The second support portion 7 has a rigid frame structure. Therefore, the support rigidity in the vertical direction Dv for the compressor 1 can be further increased. As a result, since the compressor 1 is arranged at a higher position than the second support portion 7, even if a force (pulling force) that pulls out the column portion 75 occurs due to the weight of the compressor 1, the second support portion 7 can maintain a stable state against this pulling force. Therefore, the compressor 1 arranged at a higher position can be stably supported.

[0056] The third cooling section 43 and the fourth cooling section 44 are fixed to the third support section 8, which has a rigid frame structure similar to the second support section 7. The third support section 8 is disposed adjacent to the second support section 7 in the width direction Dw. The third support section 8 constitutes a transportable third unit C with the third cooling section 43 and the fourth cooling section 44 fixed thereto. Therefore, the third cooling section 43 and the fourth cooling section 44, which are fixed and positioned, can be placed at a specified installation position simply by transporting the third support section 8. Therefore, the installation work of the third cooling section 43 and the fourth cooling section 44 can be shortened. In other words, by using not only the first unit A and the second unit B but also the third unit C, the installation work of more cooling sections 4 can be shortened, and the installation work of the compressor module 100 can be further shortened.

[0057] In addition, the first cooling section 41 and the second cooling section 42 arranged inside the second support section 7, and the third cooling section 43 and the fourth cooling section 44 arranged inside the third support section 8 are configured in a bundle structure in which the heat exchange section, which is an internal component, can be attached and detached to the shell 40 by moving them in the axial direction Da. Therefore, even if the second upper frame 7a is arranged above the cooling section 4, the maintainability of the cooling section 4 is not impaired.

[0058] Further, the fifth cooling section 45 and the sixth cooling section 46 are fixed to the fourth support section 9. The fourth support section 9 is disposed adjacent to the first support section 6 in the width direction Dw. The fourth support section 9 constitutes a fourth unit D that can be transported with the fifth cooling section 45 and the sixth cooling section 46 fixed thereto. Therefore, the fifth cooling section 45 and the sixth cooling section 46 that are fixed and positioned can be placed at a specified installation position simply by transporting the fourth support section 9. Therefore, the installation work of the fifth cooling section 45 and the sixth cooling section 46 can be shortened. In other words, by using not only the first unit A to the third unit C but also the fourth unit D, the installation work of even more cooling sections 4 can be shortened, and the installation work of the compressor module 100 can be further shortened.

[0059] Furthermore, the fourth support portion 9 is not arranged in line with the second support portion 7 and the third support portion 8 in the width direction Dw, but is arranged above the third support portion 8 in the vertical direction Dv and adjacent to the first support portion 6 in the width direction Dw. This allows the fifth cooling portion 45 and the sixth cooling portion 46 to be positioned closer to the compressor 1. This allows the connection pipes, such as the expansion joint 49, that connect the fifth cooling portion 45 and the sixth cooling portion 46 to the compressor 1 to be shortened.

[0060] Moreover, unlike the first support portion 6 and the second support portion 7, the rotary driver 2 is supported on the foundation 200 by a drive support portion 25, which is a concrete base. The rotary driver 2 that drives the compressor 1 is heavier than the compressor 1 and is prone to greater vibrations during operation. The drive support portion 25 of such a rotary driver 2 is fixed on the foundation 200 at a position independent of the first support portion 6 and the second support portion 7. This prevents the first support portion 6 and the second support portion 7 from being adversely affected by the weight and vibrations of the rotary driver 2.

[0061] In addition, the oil console device is disposed below the compressor 1 and the rotary drive 2 in the vertical direction Dv. Therefore, it is easy to ensure a gradient for recovering the lubricating oil used in the compressor 1 and the rotary drive 2. Furthermore, the oil console device is directly fixed to the foundation 200, independent of the first support 6, the second support 7, the third support 8, the fourth support 9, and the drive support 25. Therefore, nothing is disposed above the oil console device in the vertical direction Dv. Therefore, it is possible to ensure accessibility to the oil console device 5 having multiple devices from above in the vertical direction Dv during maintenance. In addition, the oil console device 5 having multiple devices may be required to have a large installation space. Even in such a case, it is easy to ensure the installation space by being directly fixed to the foundation 200.

[0062] (Other embodiments) Although the embodiments of the present disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes and the like that do not depart from the gist of the present disclosure are also included.

[0063] The compressor 1 is not limited to a geared compressor, but may be another type of compressor 1 such as a multi-stage centrifugal compressor.

[0064] Furthermore, the rotary driver 2 is not limited to being an electric motor, but may be any device capable of driving the compressor 1. Therefore, the rotary driver 2 may be a steam turbine or a gas turbine.

[0065] Furthermore, the configuration of the compressor module 100 of this embodiment is not limited to the configuration of the above embodiment. For example, the compressor module 100 may have a structure including only the first unit A and the second unit B without including the fourth unit D and the third unit C.

[0066] Moreover, it is not limited to only the compressor 1 and the gas supply device 3 being fixed onto the first support part 6. For example, another cooling part 4 may be fixed onto the first support part 6. Moreover, it is not limited to only the first cooling part 41 and the second cooling part 42 being fixed onto the second support part 7. Three or more cooling parts 4 including the other cooling parts 4 may be fixed onto the second support part 7. Similarly, it is not limited to only the third cooling part 43 and the fourth cooling part 44 being fixed onto the third support part 8. Three or more cooling parts 4 including the other cooling parts 4 may be fixed onto the third support part 8.

[0067] In addition, the structures of the first support portion 6, the second support portion 7, the third support portion 8, and the fourth support portion 9 are not limited to the above-mentioned structures. Furthermore, the first support portion 6, the second support portion 7, the third support portion 8, and the fourth support portion 9 may each have a different structure.

[0068] <Additional Notes> The compressor module 100 according to the embodiment can be understood, for example, as follows.

[0069] (1) A compressor module 100 according to a first embodiment includes a compressor 1 having a rotating shaft 1a rotating around an axis O and capable of compressing a fluid in stages, a gas supply device 3 supplying a seal gas to the compressor 1, a plurality of cooling sections 4 cooling the fluid compressed by the compressor 1, a first support part 6 supporting the compressor 1 and the gas supply device 3 from below in the vertical direction Dv, and a second support part 7 fixed directly below the first support part 6 in the vertical direction Dv and supporting at least two cooling sections 4 from below in the vertical direction Dv, the second support part 7 being formed in a rectangular shape by a plurality of column parts 75 extending in the vertical direction Dv and a plurality of beam parts extending horizontally, the first support part 6 being transportable with the compressor 1 and the gas supply device 3 connected by piping 31 fixed thereto, and the second support part 7 being transportable with at least two of the cooling sections 4 fixed thereto.

[0070] As a result, at least two cooling units 4 in a fixed and position-defined state can be arranged at a specified installation position simply by transporting the second support unit 7. Therefore, the installation work of the cooling units 4 can be shortened. Similarly, the compressor 1 and the gas supply device 3 in a fixed and position-defined state can be arranged at the installation position of the compressor module 100 simply by transporting the first support unit 6 and fixing it on the second support unit 7. In particular, the compressor 1 and the gas supply device 3 are already connected to the piping 31. Therefore, after the compressor 1 and the gas supply device 3 are arranged, the work of separately connecting the piping 31 between the compressor 1 and the gas supply device 3 is not required. Therefore, the installation work of the compressor 1 and the gas supply device 3 can be shortened. As a result, the installation work of the compressor module 100 can be shortened.

[0071] (2) A compressor module 100 according to a second aspect is a compressor module 100 of (1), wherein the compressor 1 has at least a first compression section 11 that compresses the fluid and a second compression section 12 that compresses the fluid compressed by the first compression section 11, and the plurality of cooling sections 4 have at least a first cooling section 41 that cools the fluid compressed by the first compression section 11 and can supply it to the second compression section 12, and a second cooling section 42 that cools the fluid compressed by the second compression section 12 and can supply it to the third compression section 13, the first cooling section 41 has the largest volume among the plurality of cooling sections 4, and the second support section 7 is capable of being transported with the first cooling section 41 and the second cooling section 42 fixed thereto.

[0072] As a result, the cooling section 4 having the greatest weight among the multiple cooling sections 4 is disposed below the compressor 1 in the vertical direction Dv. Therefore, even if the compressor 1 is disposed at a high position, the compressor 1 can be stably supported by the first cooling section 41 and the second cooling section 42, which are heavy objects.

[0073] (3) The compressor module 100 according to a third aspect is the compressor module 100 of (2), in which the first cooling section 41 and the second cooling section 42 are connected to the compressor 1 by expansion joints 49, respectively.

[0074] As a result, even if the positions of the first cooling section 41 and the second cooling section 42 and the compressor 1 are misaligned when the first support section 6 and the second support section 7 are fixed, the expansion joint 49 can absorb the installation error between the compression section 10 and the cooling section 4.

[0075] (4) A compressor module 100 according to a fourth aspect is a compressor module 100 according to any one of (2) to (4), wherein the second support portion 7 has at least one pillar portion 75 located between the first cooling portion 41 and the second cooling portion 42 in the horizontal direction and at a position overlapping with the compressor 1 when viewed from the direction in which the axis O extends.

[0076] This allows the compressor 1 to be supported from below in the vertical direction Dv by at least one column portion 75. As a result, the support rigidity in the vertical direction Dv for the compressor 1 can be increased compared to the case where the compressor 1 is supported only by a beam member extending in the horizontal direction.

[0077] (5) A compressor module 100 according to a fifth aspect is a compressor module 100 according to any one of (2) to (5), and further includes a third support portion 8 that supports at least two of the cooling portions 4 different from the second support portion 7 from below in the vertical direction Dv, and the compressor 1 further includes a third compression portion 13 that compresses the fluid compressed in the second compression portion 12 and a fourth compression portion 14 that compresses the fluid compressed in the third compression portion 13, and the cooling portions 4 are compressed in the third compression portion 13. The device further includes a third cooling section 43 capable of cooling the compressed fluid and supplying it to the fourth compression section 14, and a fourth cooling section 44 capable of cooling the fluid compressed in the fourth compression section 14, and the third support section 8 is formed in a rectangular shape by a plurality of column sections 75 extending in the vertical direction Dv and a plurality of beam sections extending in the horizontal direction, and the third support section 8 is arranged adjacent to the second support section 7 in the horizontal direction, and the third cooling section 43 and the fourth cooling section 44 are capable of being transported in a fixed state.

[0078] As a result, the third cooling section 43 and the fourth cooling section 44, which are fixed and positioned, can be placed in the designated installation position simply by transporting the third support section 8. This makes it possible to shorten the installation work of the third cooling section 43 and the fourth cooling section 44. In other words, the installation work of more cooling sections 4 can be shortened, and the installation work for the compressor module 100 can be further shortened.

[0079] (6) A compressor module 100 according to a sixth aspect is the compressor module 100 according to any one of (2) to (5), and includes a fourth support portion 9 that supports at least two of the cooling portions 4 different from the second support portion 7 and the third support portion 8 from below in the vertical direction Dv, and the compressor 1 further includes a fifth compression portion 15 that compresses the fluid compressed in the fourth compression portion 14 and a sixth compression portion 16 that compresses the fluid compressed in the fifth compression portion 15, The cooling section 4 further has a fifth cooling section 45 which cools the fluid compressed in the fifth compression section 15 and can supply it to the sixth compression section 16, and a sixth cooling section 46 which can cool the fluid compressed in the sixth compression section 16, and the fourth support section 9 is arranged above the third support section 8 in the vertical direction Dv and adjacent to the first support section 6 in the horizontal direction, and the fifth cooling section 45 and the sixth cooling section 46 are capable of being transported in a fixed state.

[0080] As a result, the fifth cooling section 45 and the sixth cooling section 46, which are fixed and positioned, can be placed in the designated installation position simply by transporting the fourth support section 9. This makes it possible to shorten the installation work of the fifth cooling section 45 and the sixth cooling section 46. In other words, the installation work of even more cooling sections 4 can be shortened, and the installation work for the compressor module 100 can be further shortened.

[0081] (7) The compressor module 100 according to the seventh aspect is any one of the compressor modules 100 of (1) to (6), and further includes a rotary drive 2 having an output shaft 2a that is driven to rotate around the axis O and capable of transmitting the rotation of the output shaft 2a to drive the compressor 1, wherein the rotary drive 2 is arranged in line with the compressor 1 in the axial direction Da in which the axis O extends, in a position that does not overlap with the first support portion 6 and the second support portion 7 when viewed from the vertical direction Dv.

[0082] As a result, the drive support part 25 of the rotary drive machine 2 is fixed at a position independent of the first support part 6 and the second support part 7. Therefore, adverse effects of the weight and vibration of the rotary drive machine 2 on the first support part 6 and the second support part 7 are suppressed. [Explanation of symbols]
