[0027] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0030] In an embodiment of the present application, a reciprocating compressor skid is provided. For the convenience of description and understanding, the following content provided by the present application is all elaborated on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only a specific example and schematic description, and does not constitute a specific limitation on the technical solution provided by the present application.

[0031] As Figure 1 and Figure 2 shown, a reciprocating compressor skid provided by the present application includes a base 11 and a compressor unit disposed on the base 11. The compressor unit includes a drive motor 12, a filter 13, a crankcase 14, a compression cylinder module, a buffer module, and a cooling module. The crankcase 14 is arranged in the middle area of the base 11, and the compression cylinder module is arranged on both sides of the base 11 along the width direction. The reciprocating compressor skid further includes a maintenance workbench 18 and a ladder 19 disposed outside the compression cylinder module along the width direction. The maintenance workbench 18 includes a table surface portion 181, and the table surface portion 181 is higher than the base 11. The ladder 19 connects the foundation and the table surface portion 181.

[0032] In the reciprocating compressor skid provided by the present application, the crankcase 14 is arranged in the middle area of the base 11, and the compression cylinder module is arranged on both sides of the base 11 along the width direction, so that in addition to the compression cylinder module, components such as the intermediate body connecting the compression cylinder module and the coupling connecting the crank, which need to be frequently maintained or replaced in the reciprocating compressor, are also located at or near the edge area of the base 11 along the width direction. Thus, maintenance personnel do not need to climb onto the base 11 to maintain or replace these components, and only need to perform maintenance on these components outside the base 11, avoiding the difficulty of maintenance caused by the small standing space on the base 11 and the safety risks caused by the interference of various components of the compressor unit distributed on the base 11 to the maintenance work. In addition, the compressor unit is arranged on the base 11, and the overall height is relatively high. It is very difficult for maintenance personnel to directly perform maintenance work on the foundation. Therefore, a maintenance workbench 18 and a ladder 19 are provided outside the base 11. The maintenance workbench 18 is arranged around the compression cylinder module, so that maintenance personnel can enter the maintenance workbench 18 through the ladder 19 and perform maintenance work on relevant components on the maintenance workbench 18, and can easily reach the positions that need to be operated, with convenient, fast, and safe operation. Specifically, the base 11 can be integrally designed in a cuboid shape, with a simple structure and convenient for the assembly of the compressor unit.

[0033] It should be noted that the present application does not limit the form of the compressor unit, which can be either a single-stage compressor or a multi-stage compressor. Figure 1The illustrated embodiment is in the form of a two-stage compressor. Specifically, the compression cylinder module includes a first-stage compression cylinder 151 and a second-stage compression cylinder 152, and the two maintenance workbenches 18 are respectively arranged around the first-stage compression cylinder 151 and the second-stage compression cylinder 152; the buffer module includes a first-stage intake buffer tank 161, a first-stage exhaust buffer tank 162, a second-stage intake buffer tank 163 and a second-stage exhaust buffer tank 164, the cooling module includes a first-stage cooling tank 171 and a second-stage cooling tank 172, and the filter 13, the first-stage intake buffer tank 161, the air cavity of the first-stage compression cylinder 151, the first-stage exhaust buffer tank 162, the first-stage cooling tank 171, the second-stage intake buffer tank 163, the air cavity of the second-stage compression cylinder 152, the second-stage exhaust buffer tank 164, and the second-stage cooling tank 172 are connected in sequence. Among them, the first-stage compression cylinder 151 is used to perform first-stage compression on the gas, and the second-stage compression cylinder 152 is used to perform second-stage compression on the gas. The number of the first-stage compression cylinder 151 and the second-stage compression cylinder 152 can be one or multiple. Figure 1 In the illustrated embodiment, the number of the first-stage compression cylinder 151 and the second-stage compression cylinder 152 is three each. The first-stage compression cylinder 151 and the second-stage compression cylinder 152 can be arranged in sub-regions at the edge of the base 11, and the two maintenance workbenches 18 are respectively arranged around the first-stage compression cylinder 151 and the second-stage compression cylinder 152, so that maintenance personnel can perform maintenance on the first-stage compression cylinder 151, the intermediate body connecting the first-stage compression cylinder 151 and the crankcase 14, the coupling, etc. on the maintenance workbench corresponding to the first-stage compression cylinder 151, and perform maintenance on the second-stage compression cylinder 152, the intermediate body connecting the second-stage compression cylinder 152 and the crankcase 14, the coupling, etc. on the maintenance workbench corresponding to the second-stage compression cylinder 152. In the compressor unit of the present application, the drive motor 12 serves as the power source for driving the crankshaft in the crankcase 14. The gas medium first enters the filter 13, then enters the first-stage intake buffer tank 161 to buffer and smooth the flow rate, then enters the air cavity of the first-stage compression cylinder 151 for first-stage compression and then enters the first-stage exhaust buffer tank 162 to buffer and smooth the flow rate, then enters the first-stage cooling tank 171 to cool down, then enters the second-stage intake buffer tank 163 to buffer and smooth the flow rate, then enters the air cavity of the second-stage compression cylinder 152 for second-stage compression and then enters the second-stage exhaust buffer tank 164 to buffer and smooth the flow rate, and finally enters the second-stage cooling tank 172 to cool down to obtain the required gas compression medium.

[0034] Further, as Figure 1As shown, along the length direction of the base 11, the primary cooling tank 171 and the secondary cooling tank 172 are located on one side of the crankcase 14, and the drive motor 12 and the filter 13 are located on the other side of the crankcase 14; along the width direction of the base 11, the primary compression cylinder 151 and the secondary compression cylinder 152 are distributed on both sides of the crankcase 14; one of the primary intake buffer tank 161 and the primary exhaust buffer tank 162 is located above the primary compression cylinder 151, and the other is located below the primary compression cylinder 151; one of the secondary intake buffer tank 163 and the secondary exhaust buffer tank 164 is located above the secondary compression cylinder 152, and the other is located below the secondary compression cylinder 152. With this layout, the compressor unit is compactly arranged on the base 11, making rational use of space, reducing spatial redundancy, contributing to the miniaturization of the entire skid-mounted unit. Moreover, it also reserves a broad design and installation space for the maintenance workbench 18 on both sides of the base 11 and the elevated platform 20 at one end of the base 11, increasing the spaciousness of the maintenance workbench 18 and the elevated platform 20, and facilitating the maintenance operation of maintenance personnel. This application schematically shows an embodiment in which the primary exhaust buffer tank 162 and the secondary exhaust buffer tank 164 are respectively arranged above the primary compression cylinder 151 and the secondary compression cylinder 152, and the primary intake buffer tank 161 and the secondary intake buffer tank 163 are respectively arranged below the primary compression cylinder 151 and the secondary compression cylinder 152. As an alternative embodiment, it is also possible to arrange the primary exhaust buffer tank 162 and the secondary exhaust buffer tank 164 respectively below the primary compression cylinder 151 and the secondary compression cylinder 152, and the primary intake buffer tank 161 and the secondary intake buffer tank 163 respectively above the primary compression cylinder 151 and the secondary compression cylinder 152.

[0035] Further, as Figure 1 shown, at least a part of the exhaust pipe 173 of the secondary cooling tank 172 is arranged below the table surface portion 181. With this arrangement, on the one hand, the exhaust pipe 173 of the secondary cooling tank 172 utilizes the redundant space below the table surface portion 181, making the compressor unit as a whole more compact. On the other hand, it also avoids interference of the exhaust pipe 173 with the installation position of the maintenance workbench 18 and the process of maintenance personnel ascending to the table surface portion 181.

[0036] Regarding the specific structure of the table surface portion 181, in a preferred embodiment, as Figure 1 and Figure 2As shown, the tabletop portion 181 is higher than the base 11. The tabletop portion 181 includes a lower layer support structure 1811 and an upper layer stepping structure 1812. The lower layer support structure 1811 includes a plurality of steel pipes welded together, and the upper layer stepping structure 1812 is provided as a steel grating plate. Specifically, the lower layer support structure 1811 with an overall flat plate-like structure can be formed by welding together a plurality of rectangular steel pipes of the same specification, and then the steel grating plate is placed above the lower layer support structure 1811 to form the upper layer stepping structure 1812. The tabletop portion 181 being higher than the base 11 enables maintenance personnel to stand on the tabletop portion 181 which is overall higher than the compressor unit, facilitating maintenance. The lower layer support structure 1811 includes a plurality of steel pipes welded together, and the upper layer stepping structure 1812 is also made of steel, which can obtain better structural strength and stability. The upper layer stepping structure 1812 is provided as a steel grating plate, and the grating structure enables the tabletop portion 181 to have better water seepage effect and anti-slip effect, so that the water falling on the tabletop portion 181 due to reasons such as rain and snow weather can leak downward through the steel grating plate, avoiding the wet and slippery phenomenon caused by water accumulation, and improving the safety factor of the maintenance work.

[0037] In a preferred embodiment, the tabletop portion 181 is higher than the base 11, the tabletop portion 181 is connected to the base 11 or the compression cylinder module, and the maintenance workbench 18 further includes a plurality of support portions 182 for supporting the tabletop portion 181. The lower ends of the support portions 182 are connected to the foundation, and the upper ends of the support portions 182 are connected to the tabletop portion 181. Specifically, one side of the tabletop portion 181 close to the base 11 can be bolted to the base 11 or the compression cylinder module to ensure stability. By supporting the tabletop portion 181 on the foundation through the support portions 182, reliable support for the tabletop portion 181 can also be formed, improving the load-bearing capacity of the tabletop portion 181. Further, the support portions 182 are provided as steel pipe structures, and the upper ends of the support portions 182 are detachably connected to the tabletop portion 181 by bolts, so as to facilitate disassembly, repair or replacement when the support portions 182 or the tabletop portion 181 are damaged.

[0038] As a preferred embodiment, as Figure 1 and Figure 2As shown, the maintenance workbench 18 further includes a maintenance protection fence 183. The maintenance protection fence 183 is detachably arranged around the outer edge of the table surface part 181, and the maintenance protection fence 183 is a frame structure welded by steel pipes. By surrounding the table surface part 181 with the maintenance protection fence 183, a protection effect is formed, greatly reducing the high-altitude operation risk of maintenance personnel on the table surface part 181. The maintenance protection fence 183 is a frame structure welded by steel pipes, with high structural strength and not easily deformed or damaged. The maintenance protection fence 183 is detachable, which is convenient for maintenance and replacement. Specifically, the steel pipes of the maintenance protection fence 183 can be inserted into the table surface part 181 to form a detachable manner. Specifically, as Figure 1 shown, the ladder 19 includes inclined braces 191 on both sides and a plurality of treads 192 connected between the inclined braces 191 on both sides. Specifically, the bottom of the inclined braces 191 can be connected to the foundation, and the top of the inclined braces 191 can be connected to the table surface part 181 to form a reliable support.

[0039] As a preferred embodiment, as Figure 1 shown, the filter 13 is arranged at one end of the base 11 along the length direction. The reciprocating compressor skid further includes a climbing platform 20 and a straight ladder 21 arranged outside the base 11. The climbing platform 20 is arranged around the filter 13, and the straight ladder 21 is connected to the climbing platform 20. The filter element of the filter 13 is a consumable and needs to be replaced regularly. However, the filter 13 is usually vertically placed on the base 11, and the filter element needs to be replaced at the top of the filter 13. Therefore, in this application, the filter 13 is arranged at one end of the base 11 along the length direction, and a climbing platform 20 surrounding the filter 13 is arranged outside the base 11, and the climbing platform 20 is connected with a straight ladder 21, so that maintenance personnel can enter the climbing platform 20 through the straight ladder 21 and easily reach the position to be operated on the climbing platform 20 to replace the filter element, with convenient, fast and safe operation.

[0040] Further, the climbing platform 20 includes a platform 201 and a filter element replacement protection fence 202 surrounding the platform 201. The platform 201 and the filter element replacement protection fence 202 are respectively connected to the filter 13. By surrounding the platform 201 with the filter element replacement protection fence 202, a protection effect is formed, greatly reducing the high-altitude operation risk of maintenance personnel on the platform 201. The platform 201 and the filter element replacement protection fence 202 can be respectively connected to the outer wall of the filter 13 by welding or bolt connection. Preferably, the climbing platform 20 can also be designed as a two-layer structure. The lower layer structure is welded and assembled by steel pipes, and the upper layer structure is a steel grating plate to improve the water seepage effect.
