Technical Field

[0002] A barrel compressor is a special type of compressor, usually consisting of a cylindrical shell and a rotor, which is driven by an electric motor and has structures such as blades or cams for compressing gas. The air inlet and exhaust ports of a barrel compressor are located on both sides of the shell. Due to its simple structure and high reliability, it is widely used in gas compression scenarios with medium pressure and flow; however, due to its structural limitations, the pressure and flow range of barrel compressors is relatively small, and more electricity is required to drive it.

[0003] When both cylinders of the compressor unit are barrel compressors and driven by an electric motor, the barrel compressor in the middle position needs to be hoisted onto the maintenance base for core extraction during unit maintenance. This not only requires an additional maintenance base and space for the maintenance base, but also requires the inlet and outlet of the compressor to be disconnected from the main process gas pipeline, making the maintenance operation complicated and the maintenance efficiency low.

[0040] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0042] like Figure 1As shown, according to an embodiment of the present application, a base structure of a cylindrical compressor unit is proposed, including: a main support seat 11, a compressor support seat 12 and a gearbox support seat 13; the compressor support seat 12 is connected to the cylindrical compressor, and the compressor support seat 12 is arranged on the main support seat 11 to fix the cylindrical compressor on the main support seat 11; the gearbox support seat 13 is connected to the gearbox 103, and the gearbox support seat 13 is detachably arranged on the main support seat 11 so that the gearbox 103 is detachably connected to the main support seat 11.

[0043] The base structure of the cylindrical compressor unit provided in the embodiment of the present application includes a main support base 11, a compressor support base 12 and a gearbox support base 13; the compressor support base 12 is used to support the cylindrical compressor, and the gearbox support base 13 is used to support the gearbox 103. The gearbox support base 13 is detachably connected to the main support base 11 to remove the gearbox 103 from the main support base 11. Since the cylindrical compressor is connected to the gearbox 103, when the gearbox 103 and the gearbox support base 13 are removed, the input end of the cylindrical compressor can form a sufficiently large maintenance space, and the compressor unit can be directly repaired without disconnecting the compressor from the main process pipeline, eliminating the steps of disconnecting and reconnecting the pipeline during maintenance, which can speed up the maintenance process and improve the maintenance efficiency; moreover, the gearbox 103 is smaller in size and lighter in weight than the compressor. Removing the gearbox 103 instead of disassembling the cylindrical compressor is more labor-saving and convenient during lifting, and the operation difficulty is low, which is conducive to further improving the maintenance efficiency.

[0044] It is understandable that during maintenance, it is necessary to perform core pulling operation on the cylindrical compressor. When it is necessary to pull the core of the partition bundle of the cylindrical compressor, the gearbox support seat 13 is removed, and the space formed for maintenance is sufficient to install the partition bundle removal tool of the cylindrical compressor.

[0045] like Figure 2 and Figure 3 As shown, in a feasible embodiment, the cylindrical compressor unit 10 includes two cylindrical compressors, a gearbox 103, a coupling 104 and a driving device 105; the output end of the driving device 105 is connected to the input end of the gearbox 103 through the coupling 104, the output end of the gearbox 103 is connected to the input end of the first cylindrical compressor 101, and the output end of the first cylindrical compressor 101 is connected to the second cylindrical compressor 102, wherein the base structure is used to support the first cylindrical compressor 101, the second cylindrical compressor 102 and the gearbox 103.

[0046] In this technical solution, the driving device 105, the coupling 104, the gearbox 103, the first cylindrical compressor 101 and the second cylindrical compressor 102 are connected in sequence, the main support base 11 supports the gearbox 103, the first cylindrical compressor 101 and the second cylindrical compressor 102, and the driving device 105 is supported by an independent base and is separated from the compressor to avoid vibration and noise during the operation of the driving device 105, which may interfere with the first cylindrical compressor 101 and the second cylindrical compressor 102; when the first cylindrical compressor 101 needs to be overhauled, the driving device 105 can be moved to expand the overhaul space; and when the driving device 105 needs to be replaced or overhauled, it does not need to be disassembled, and the entire unit does not need to be moved, which can more flexibly adapt to the layout of the unit to meet different installation environments and requirements.

[0047] like Figure 2 and Figure 3 As shown, in a feasible implementation manner, after the gearbox support seat 13 is removed from the main support seat 11 , an inspection space is formed between the coupling 104 and the first cylindrical compressor 101 .

[0048] In this technical solution, by removing the gearbox support base 13 from the main support base 11, a maintenance space is quickly formed at the supporting end of the first cylindrical compressor 101. There is no need to disassemble and lift the first cylindrical compressor 101, and there is no need to disconnect and reconnect the main process pipeline. The first cylindrical compressor 101 can be directly maintained in the maintenance space formed between the first cylindrical compressor 101 and the driving device 105. The operation is simple, time-saving and labor-saving, and it is beneficial to improve the overall maintenance efficiency of the unit.

[0049] It should be noted that, when pulling the core, the core pulling direction of the cylindrical compressor is different from the conventional core pulling direction. For the conventional cylindrical compressor core pulling, the thrust end cover of the intermediate compressor is removed and the partition bundle is pulled out from the thrust bearing end. When the support end of the first cylindrical compressor 101 is formed with an inspection space by lifting the gearbox 103, it is necessary to perform inspection from the support end of the first cylindrical compressor 101. Therefore, it is necessary to remove the support end cover of the first cylindrical compressor 101 and pull out the partition bundle from the support bearing end. Therefore, when designing the casing of the first cylindrical compressor 101, its support end is the positioning end of the partition bundle, and from the support end to the thrust end, the inner diameter of the partition stop becomes smaller. At the same time, the roller position design on the partition bundle also needs to be adaptively adjusted to ensure that the partition bundle can be pulled out smoothly.

[0050] like Figure 4 As shown, in a feasible implementation manner, the compressor support seat 12 includes two support seats, the first support seat 121 is connected to the first cylindrical compressor 101, and the second support seat 122 is connected to the second cylindrical compressor 102, so as to separately support the two cylindrical compressors.

[0051] In this technical solution, the first cylindrical compressor 101 and the second cylindrical compressor 102 are supported by the first support base 121 and the second support base 122 respectively, so that the height and position of the first cylindrical compressor 101 and the second cylindrical compressor 102 can be adjusted independently, so that the gas input end of the second cylindrical compressor 102 can be accurately docked with the gas output end of the first cylindrical compressor 101, so as to avoid the deviation of the center of gravity of the unit, ensure the stability and reliability of the operation of the unit, and make the structure of the whole system more compact and save space.

[0052] like Figure 1 As shown, in a feasible implementation manner, a threaded hole is provided on the main support seat 11 , and the gearbox support seat 13 is threadedly connected to the threaded hole through a bolt 14 , so that the gearbox support seat 13 is assembled on the main support seat 11 .

[0053] In this technical solution, the gearbox support seat 13 is fastened to the main support seat 11 by bolts 14, so that the gearbox support seat 13 and the main support seat 11 are detachably connected, and the threaded engagement can prevent the connection from loosening, ensuring that the gearbox support seat 13 is tightly pressed against the main support seat 11, thereby ensuring the reliability and stability of the connection between the gearbox 103 and the main support seat 11.

[0054] like Figure 4 As shown, in a feasible implementation manner, the gearbox support seat 13 includes two symmetrically arranged supports 130 , and the supports 130 are arranged at the bottom of the gearbox 103 along the length direction of the gearbox 103 .

[0055] In this technical solution, the gearbox support seat 13 is composed of two supports 130. Compared with a single support seat, the design of the two supports 130 can not only ensure stable and effective support for the gearbox 103, but also reduce the volume and weight of the entire gearbox support seat 13, thereby saving more effort when disassembling and hoisting the gearbox 103.

[0056] like Figure 4 and Figure 5As shown, in a feasible embodiment, the support 130 includes: a bottom plate 131, a connecting plate 132, a top plate 133 and a reinforcement plate 134; the bottom plate 131 is arranged along the length direction of the gearbox 103, and the bottom plate 131 is fixed on the top surface of the general support seat 11 by bolts 14; the connecting plate 132 is vertically arranged on the top surface of the bottom plate 131, and the first end of the connecting plate 132 is welded and connected to the bottom plate 131; the top plate 133 is arranged along the length direction of the gearbox 103, and the top plate 133 is vertically welded and connected to the second end of the connecting plate 132, and the top plate 133, the connecting plate 132 and the bottom plate 131 are surrounded to form a reinforcement cavity; the reinforcement plate 134 is vertically arranged between the bottom plate 131 and the top plate 133, and the reinforcement plates 134 are arranged in the reinforcement cavity at equal intervals along the length direction of the top plate 133.

[0057] In this technical solution, the bottom plate 131 is detachably connected to the main support seat 11 by bolts 14, the connecting plate 132 is used to fix the top plate 133 and raise the top plate 133, and the top plate 133 extends along the length direction of the gearbox 103 to increase the contact area with the gearbox 103, so that the gearbox 103 can be stably and effectively supported; because the bottom plate 131, the connecting plate 132 and the top plate 133 are surrounded by a hollow reinforcement cavity, it can not only play a role in weight reduction, but also provide an installation space for the reinforcement plate 134, and then the top plate 133 is supported and reinforced by the reinforcement plate 134, thereby improving the bearing capacity of the top plate 133, making the support 130 structure reliable, thereby improving the stability and reliability of the gearbox support seat 13 supporting the gearbox 103.

[0058] In this technical solution, by arranging the reinforcement plates 134 at equal intervals along the length direction of the top plate 133 and then arranging the reinforcement plates 134 at equal intervals along the length direction of the gearbox 103, it is ensured that the weight of the gearbox 103 can be more evenly distributed on the support 130, which is beneficial to improving the bearing capacity of the support 130, thereby improving the safety and stability of the overall structure of the support 130.

[0059] Furthermore, a gasket 16 is provided between the base plate 131 and the main support seat 11 to avoid a gap between the base plate 131 and the main support seat 11, ensure the stability of the connection between the base plate 131 and the main support seat 11, prevent the bolts 14 from loosening, and ensure that the reduction gearbox support seat and the support seat are reliably installed.

[0060] like Figure 5As shown, in a feasible embodiment, the support 130 also includes: a positioning hole 135 and a mounting hole 136; at least two positioning holes 135 are symmetrically arranged on the bottom plate 131 near the two ends of the bottom plate 131, and the positioning holes 135 are used to install the positioning pins 15; the mounting holes 136 are evenly spaced along the length direction of the bottom plate 131 on the bottom plate 131, and the mounting holes 136 are used to install the bolts 14; wherein, after the gearbox support seat 13 is accurately positioned, the mounting holes 136 coincide axially with the threaded holes.

[0061] In this technical solution, the locating pin 15 is embedded in the locating hole 135 and the main support seat 11 at the same time to position the base plate 131. The two locating holes 135 are respectively located on the base plate 131 near the two ends so that the distance between the two locating holes 135 is closer to the length of the base plate 131, thereby improving the accuracy of the locating pin 15 in positioning the base plate 131. By equidistantly arranging the mounting holes 136, even after the gearbox support seat 13 is installed, the bolts 14 are equidistantly arranged on the support 130, which can prevent local stress concentration, reduce structural deformation and loosening, and improve the bearing capacity and seismic resistance of the base plate 131, thereby ensuring the firmness and stability of the connection of the support 130.

[0062] Furthermore, the spacing between the positioning holes 135 is equal to the sum of the spacing between the reinforcing plates 134 and the thickness of the reinforcing plates 134 .

[0063] like Figure 4 As shown, in a feasible implementation manner, the support 130 further includes: a lifting ring 137 ; at least two lifting rings 137 are symmetrically arranged at both ends of the top plate 133 , and the lifting rings 137 are used to lift the gearbox support seat 13 .

[0064] In this technical solution, a lifting ring 137 is provided on the top plate 133 so that the lifting position is close to the middle height between the gearbox 103 and the gearbox support seat 13, thereby preventing the gearbox 103 from tipping over during the lifting process, improving the stability of the gearbox 103 when it is lifted, and preventing the gearbox 103 from being damaged due to tipping over and inverting.

[0065] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0066] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
