Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal compressors, and more specifically, particularly to a magnetic suspension centrifugal compressor parallel unit. Background Art

[0002] Like traditional centrifugal compressors, magnetic levitation centrifugal compressors are composed of imported energy regulating mechanisms (inlet guide vanes), impeller rotors, diffusers, volute chambers, drive devices and bearings. In traditional centrifugal compressors, the rotors are supported by mechanical bearings and complete the gas compression process at high-speed rotation, but mechanical bearings have friction losses and require regular maintenance and replacement of lubricating oil.

[0003] Multiple magnetic levitation centrifugal compressors can be connected in parallel to form an integrated refrigeration system. The advantage of this is that the working state of each compressor can be flexibly adjusted according to the actual load demand, so as to achieve precise capacity regulation and efficient partial load operation. However, when multiple magnetic levitation centrifugal compressors are used in parallel, the connection between the outlet pipe of a single magnetic levitation centrifugal compressor and the main air pipe is generally designed in advance, so that the outlet pipe is fixedly connected to the branch pipe of the main air pipe, and therefore cannot be disassembled, which makes it impossible to separate the single magnetic levitation centrifugal compressor from the parallel unit, making it impossible to flexibly use the single magnetic levitation centrifugal compressor. In addition, when the multiple magnetic levitation centrifugal compressors in the parallel unit are working, the vibrations generated are transmitted to each other, resulting in strong vibration, which can easily cause damage to the magnetic levitation centrifugal compressor.

[0023] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0024] Example:

[0025] As attached Figure 1 To Attachment Figure 6 As shown:

[0026] The utility model provides a parallel magnetic suspension centrifugal compressor unit, comprising a plurality of compressor bodies 1; an air inlet pipe 101 and an air outlet pipe 102 are respectively arranged at both ends of the compressor body 1, a main air pipe 2 is arranged at the top of the compressor body 1, a plurality of connecting air pipes 201 are connected to the bottom of the main air pipe 2, a bottom plate 3 is arranged at the bottom of the compressor body 1, universal wheels 301 are installed on four sides of the bottom of the bottom plate 3, a left outer plate 4 and a right outer plate 5 are respectively arranged on both sides of the outer end of the bottom plate 3, a sleeve connection component is arranged between the air outlet pipe 102 and the connecting air pipe 201, and a connecting component is arranged between the left outer plate 4 and the right outer plate 5.

[0027] Among them, the socket assembly includes: a connecting sleeve 6, a through hole 601 and a valve 202. A connecting sleeve 6 is provided on the outside of the air outlet pipe 102. A through hole 601 is opened at the bottom of the connecting sleeve 6, and the air outlet pipe 102 passes through the through hole 601. The inner wall of the connecting sleeve 6 and the outer wall of the connecting air pipe 201 are threadedly connected. A valve 202 is installed inside the connecting air pipe 201. A sealing sleeve 203 is provided at the bottom of the connecting air pipe 201. A sealing ring 103 is provided at the top of the air outlet pipe 102. Two limit plates 104 are provided on the outside of the air outlet pipe 102, and the limit plates 104 are located at the top and bottom of the connecting sleeve 6.

[0028] By connecting the air outlet pipes 102 of multiple compressor bodies 1 to the connecting air pipe 201, the multiple compressor bodies 1 can be arranged in parallel, thereby improving the working efficiency. When adjusting the output efficiency as needed, by rotating the connecting sleeve 6 counterclockwise, due to the threaded connection between the inner wall of the connecting sleeve 6 and the outer wall of the connecting air pipe 201, the connecting sleeve 6 moves downward when rotating counterclockwise. At this time, the air outlet pipe 102 passes through the through hole 601 opened at the bottom of the connecting sleeve 6, so that the air outlet pipe 102 is not affected when the connecting sleeve 6 rotates. Because the two limit plates 104 clamp the connecting sleeve 6, the connecting sleeve 6 drives the air outlet pipe 102 when moving downward, so that the air outlet pipe 102 is separated from the connecting air pipe 201, and then the valve 202 inside the connecting air pipe 201 is closed, and the corresponding compressor body 1 stops working, thereby reducing the overall output power.

[0029] When it is necessary to connect the air outlet pipe 102 with the connecting air pipe 201, the air outlet pipe 102 is connected to the connecting air pipe 201, and then the connecting sleeve 6 is rotated clockwise so that the connecting sleeve 6 is threadedly connected to the outer wall of the connecting air pipe 201 and moves upward, while driving the air outlet pipe 102 to connect with the connecting air pipe 201. During the upward movement of the air outlet pipe 102, the sealing ring 103 at the top thereof will enter the interior of the sealing sleeve 203. As the connecting sleeve 6 continues to drive the air outlet pipe 102 to move upward, the sealing ring 103 is squeezed, and then the air outlet pipe 102 is tightly connected to the connecting air pipe 201, thereby preventing gas leakage. Then, the valve 202 is opened and the compressor body 1 is started, so that the overall output power can be improved, and at the same time, the single compressor body 1 can be used flexibly.

[0030] Among them, the connecting component includes: four equipment grooves 401 and fixed grooves 501 are respectively opened on the opposite sides of the left outer plate 4 and the right outer plate 5 arranged on the outside of the two bottom plates 3, and a damper 402 is installed inside the equipment groove 401, a buffer rod 403 is provided on one side of the damper 402, and a buffer plate 404 is connected to one side of the buffer rod 403, and the buffer plate 404 is located inside the fixed groove 501, and bolt holes 405 are opened inside the buffer plate 404 and the buffer rod 403, and fixing bolts 502 are provided on the four sides of the outer end of the right outer plate 5, and the fixing bolts 502 extend to the fixing groove 501 and are threadedly connected with the inside of the bolt hole 405.

[0031] When multiple compressor bodies 1 need to be combined into one, the compressor bodies 1 are moved relative to each other through the universal wheels 301 at the bottom of the bottom plate 3, so that the left outer plate 4 and the right outer plate 5 outside thereof are put together. At this time, the buffer rod 403 and the buffer plate 404 enter the fixing groove 501, and then the four fixing bolts 502 are respectively rotated to screw the fixing bolts 502 into the bolt holes 405, so that the left outer plate 4 and the right outer plate 5 are fixed together, and then the two bottom plates 3 and the compressor bodies 1 above them are fixedly connected, which is convenient for multiple compressor bodies The compressor bodies 1 are transferred simultaneously, and when multiple compressor bodies 1 are working, since multiple base plates 3 are connected together, the vibrations generated during operation are transmitted to each other, which leads to strong vibrations and easily causes damage to the compressor bodies 1. At this time, the vibration force transmitted between the left outer plate 4 and the right outer plate 5 will be transmitted to the buffer plate 404, and then transmitted to the damper 402 through the buffer rod 403 by the buffer plate 404. The damper 402 absorbs the vibration force, which can weaken the vibration and then control the vibration, thereby avoiding damage to the compressor bodies 1.

[0032] Among them, a return spring 406 is provided between the damper 402 and the buffer plate 404, and the return spring 406 is sleeved on the outside of the buffer rod 403. By utilizing the return spring 406 sleeved on the outside of the buffer rod 403, the buffer plate 404 can be quickly reset to the inside of the fixing groove 501, which can avoid the separation of the fixing bolt 502 and the bolt hole 405, thereby preventing the left outer plate 4 and the right outer plate 5 from being disconnected.

[0033] Among them, hydraulic cylinders 302 are installed on all four sides of the bottom of the bottom plate 3, and support plates 303 are provided on both sides of the bottom of the bottom plate 3, and the hydraulic cylinders 302 are fixedly connected to the support plates 303. After the position of the compressor body 1 is moved to the specified position through the universal wheel 301, the hydraulic cylinder 302 is started, and the hydraulic cylinder 302 is used to push the support plate 303 downward, and the support plate 303 supports the ground, so that the bottom plate 3 and the compressor body 1 are supported by the support plate 303, thereby reducing the pressure on the universal wheel 301 and avoiding damage to the universal wheel 301.

[0034] A control console is provided outside the compressor parallel unit, and the control console is used to control the start and close of the compressor body 1, the valve 202 and the hydraulic cylinder 303. The control console, the valve 202 and the hydraulic cylinder 303 are all powered by an external power supply. The control procedures involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art, and this part is not the innovation of the utility model.

[0035] The specific usage and function of this embodiment are as follows:

[0036] By connecting the air outlet pipes 102 of multiple compressor bodies 1 to the connecting air pipe 201, the multiple compressor bodies 1 can be arranged in parallel, thereby improving the working efficiency. When adjusting the output efficiency as needed, by rotating the connecting sleeve 6 counterclockwise, due to the threaded connection between the inner wall of the connecting sleeve 6 and the outer wall of the connecting air pipe 201, the connecting sleeve 6 moves downward when rotating counterclockwise. At this time, the air outlet pipe 102 passes through the through hole 601 opened at the bottom of the connecting sleeve 6, so that the air outlet pipe 102 is not affected when the connecting sleeve 6 rotates. Because the two limit plates 104 clamp the connecting sleeve 6, the connecting sleeve 6 drives the air outlet pipe 102 when moving downward, so that the air outlet pipe 102 is separated from the connecting air pipe 201, and then the valve 202 inside the connecting air pipe 201 is closed, and the corresponding compressor body 1 stops working, thereby reducing the overall output power.

[0037] When it is necessary to connect the air outlet pipe 102 with the connecting air pipe 201, the air outlet pipe 102 is connected to the connecting air pipe 201, and then the connecting sleeve 6 is rotated clockwise so that the connecting sleeve 6 is threadedly connected to the outer wall of the connecting air pipe 201 and moves upward, while driving the air outlet pipe 102 to connect with the connecting air pipe 201. During the upward movement of the air outlet pipe 102, the sealing ring 103 at the top thereof will enter the interior of the sealing sleeve 203. As the connecting sleeve 6 continues to drive the air outlet pipe 102 to move upward, the sealing ring 103 is squeezed, and then the air outlet pipe 102 is tightly connected to the connecting air pipe 201, thereby preventing gas leakage. Then the valve 202 is opened and the compressor body 1 is started to improve the overall output power.

[0038] When multiple compressor bodies 1 need to be combined into one, the compressor bodies 1 are moved relative to each other through the universal wheels 301 at the bottom of the bottom plate 3, so that the left outer plate 4 and the right outer plate 5 outside thereof are put together. At this time, the buffer rod 403 and the buffer plate 404 enter the fixing groove 501, and then the four fixing bolts 502 are respectively rotated to screw the fixing bolts 502 into the bolt holes 405, so that the left outer plate 4 and the right outer plate 5 are fixed together, and then the two bottom plates 3 and the compressor bodies 1 above them are fixedly connected, which is convenient for multiple compressor bodies The compressor bodies 1 are transferred simultaneously, and when multiple compressor bodies 1 are working, since multiple base plates 3 are connected together, the vibrations generated during operation are transmitted to each other, which leads to strong vibrations and easily causes damage to the compressor bodies 1. At this time, the vibration force transmitted between the left outer plate 4 and the right outer plate 5 will be transmitted to the buffer plate 404, and then transmitted to the damper 402 through the buffer rod 403 by the buffer plate 404. The damper 402 absorbs the vibration force, which can weaken the vibration and then control the vibration, thereby avoiding damage to the compressor bodies 1.
