Description

Technical Field

[0001] This invention relates to the field of magnetic levitation pump accessories technology, and in particular to a vibration-damping base for a magnetic levitation pump. Background Technology

[0002] Magnetic levitation pumps, as efficient and low-noise fluid transport devices, are widely used in precision industries, laboratories, and high-end civilian fields. Their working principle dictates that the rotor is in a suspended state during operation, theoretically enabling contactless and wear-free operation. However, in actual working environments, the pump body itself still generates a certain amount of vibration and is also subject to externally transmitted vibration interference. Excessive vibration not only affects the pump's own working accuracy, efficiency, and lifespan but may also adversely affect connected piping systems and surrounding precision equipment, generating noise and even posing safety hazards.

[0003] Currently, most anti-vibration measures for pump bodies use simple rubber pads, spring isolators, or a combination of both. While these methods can isolate and attenuate vibrations to some extent, they still have the following shortcomings: existing anti-vibration measures are insufficient in buffering low-frequency vibrations and instantaneous impacts, making it difficult to meet the requirements of magnetic levitation pumps for extremely high operational stability, and the effect of multi-level and multi-dimensional vibration attenuation is not good. Summary of the Invention

[0022] The vibration-damping base of the magnetic levitation pump of the present invention uses a first buffer assembly consisting of a combination of a swing arm and springs. The magnetic levitation pump transmits vibration to the adjustment plate through a guide column below the placement plate, causing the swing arm to swing, thereby stretching or compressing the first and second springs. The elastic deformation of the two springs absorbs and consumes most of the initial vibration energy, achieving primary vibration reduction. By using a second buffer assembly consisting of a sliding damping steel plate and a connecting seat, the adjustment plate acts on the arc-shaped damping steel plate through the connecting seat while moving up and down, causing it to undergo elastic bending deformation. This process can further consume vibration energy and provide good buffering for impact loads, forming secondary vibration reduction. Furthermore, since the damping steel plate is slidably connected to the base plate, the second buffer assembly does not restrict the horizontal movement of the adjustment plate.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention and not the entire structure.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0045] like Figures 1 to 3As shown, the vibration-damping base of the magnetic levitation pump in this embodiment of the invention includes a support frame 1, a shelf 2, and a buffer mechanism. The support frame 1 includes a parallel and spaced-apart top plate 11 and a bottom plate 12, which are connected by a side plate 13. The top plate 11 has multiple guide holes 111. The shelf 2 is spaced above the top plate 11, and a mounting frame 3 is provided on the top of the shelf 2. The mounting frame 3 is used to detachably install the magnetic levitation pump 100. The buffer mechanism includes an adjusting plate 4, a guide column 5, a first buffer assembly 6, and a second buffer assembly 7. The adjusting plate 4 is movably disposed between the top plate 11 and the bottom plate 12. The upper end of the guide column 5 passes through the guide hole 111 and connects to the bottom of the shelf 2, and the lower end of the guide column 5 is connected to the adjusting plate 4. At least one first buffer assembly 6 is provided at each end of the adjusting plate 4 along a first direction. The first buffer assembly 6 includes a connector 61, a swing rod 62, a fastening frame 63, and a first spring. The first spring 64 and the second spring 65 are fixed to the upper surface of the adjusting plate 4, the fastening bracket 63 is set on the base plate 12, and the upper end of the fastening bracket 63 is higher than the upper surface of the adjusting plate 4. One end of the swing rod 62 is movably connected to the connecting member 61, and the middle part of the swing rod 62 is hinged to the fastening bracket 63 through the first rotating shaft 66. One end of the first spring 64 is connected to the upper surface of the swing rod 62 and adjacent to the connecting member 61, and the other end is connected to the top plate 11. One end of the second spring 65 is connected to the lower surface of the swing rod 62 and away from the connecting member 61, and the other end is connected to the base plate 12. Two second buffer components 7 are set on the lower surface of the adjusting plate 4 along the first direction. The second buffer component 7 includes a connecting seat 71 and a shock-absorbing steel plate 72. The shock-absorbing steel plate 72 has an upwardly convex arc structure. The connecting seat 71 is connected to the adjusting plate 4 and the shock-absorbing steel plate 72 on both sides along the vertical direction, and the shock-absorbing steel plate 72 is slidably set on the base plate 12 along the second direction.

[0046] The vibration-damping base of the magnetic levitation pump of the present invention is provided with a first buffer assembly 6 in the form of a combination of a swing rod 62 and springs. The magnetic levitation pump 100 transmits vibration to the adjusting plate 4 through the guide column 5 below the placement plate 2, which drives the swing rod 62 to swing, thereby stretching or compressing the first spring 64 and the second spring 65. The elastic deformation of the two springs absorbs and consumes most of the initial vibration energy, achieving primary vibration reduction. By providing a second buffer assembly 7 in the form of a combination of a sliding damping steel plate 72 and a connecting seat 71, the adjusting plate 4 acts on the arc-shaped damping steel plate 72 through the connecting seat 71 while moving up and down, causing it to undergo elastic bending deformation. This process can further consume vibration energy and play a good buffering role against impact loads, forming secondary vibration reduction. Since the damping steel plate 72 is slidably connected to the base plate 12, the second buffer assembly 7 does not restrict the horizontal movement of the adjusting plate 4.

[0047] In this embodiment, four guide holes 111 are rectangularly provided on the top plate 11, and four guide posts 5 are correspondingly provided. The four guide posts 5 are distributed at the four corners of the adjustment plate 4, and the four guide posts 5 are rectangularly distributed at the bottom of the shelf 2. The rectangular distribution of the four guide posts 5 enables the shelf 2 and the adjustment plate 4 to move smoothly during use.

[0048] Furthermore, two fixing plates 14 are provided at intervals along the second direction on the outer side of the side plate 13. Fixing holes are provided on the fixing plates 14. Fastening screws pass through these fixing holes to detachably fix the fixing plates 14 to the mounting surface (such as the ground, table, etc.), thereby realizing the fixation of the vibration-damping base of the entire magnetic levitation pump.

[0049] In one embodiment, such as Figure 3 and 5 As shown (some of the reference numerals in the attached figures are retained), Figure 1 and Figure 2 An adjustment hole 621 extends horizontally through the swing arm 62, with the length of the adjustment hole 621 extending along the length of the swing arm 62. The adjustment hole 621 is located on the side of the first rotating shaft 66 away from the second spring 65. The connecting piece 61 is movably connected to the swing arm 62 via the second rotating shaft 67, which is rotatably connected to the connecting piece 61. The second rotating shaft 67 is located within the adjustment hole 621 and can move along the length of the adjustment hole 621. By providing a long, narrow adjustment hole 621 and rotatably connecting the second rotating shaft 67 to the connecting piece 61, it is ensured that when the adjusting plate 4 moves up and down, the second rotating shaft 67 can slide smoothly within the adjustment hole 621 and drive the swing arm 62 to swing around the central axis of the first rotating shaft 66. This combined sliding and rotating motion efficiently converts the vertical linear motion of the adjusting plate 4 into the angular swing of the swing arm 62, thereby stretching or compressing the first spring 64 and the second spring 65. This fully utilizes the elastic deformation of the first spring 64 and the second spring 65 to absorb and consume most of the initial vibration energy generated by the magnetic levitation pump 100.

[0050] In this embodiment, the second rotating shaft 67 is a round shaft. By setting the second rotating shaft 67 as a round shaft, and considering that the second rotating shaft 67 is rotatably connected to the connecting member 61, the second rotating shaft 67 can rotate when moving within the adjusting hole 621, causing the second rotating shaft 67 to rotate into contact with the hole wall of the adjusting hole 621, reducing friction, and thus allowing the second rotating shaft 67 to move smoothly within the adjusting hole 621.

[0051] In this embodiment, when the magnetic levitation pump 100 is not in operation, the swing arm 62 is in a horizontal state. At this time, the first spring 64 and the second spring 65 are neither stretched nor compressed. The first rotating shaft 66 and the second rotating shaft 67 are located on the same horizontal plane. The connecting piece 61 and the fastening frame 63 are both provided with space to avoid the swing arm 62 swinging, so as to avoid position interference with the swing arm 62 swinging.

[0052] In addition, since the upper end of the first spring 64 is fixed to the lower surface of the top plate 11 and the lower end of the second spring 65 is fixed to the upper surface of the bottom plate 12, this fixing method clarifies the force boundaries of the first spring 64 and the second spring 65, making them effective energy storage and energy dissipation elements when the swing arm 62 swings. When the swing arm 62 swings, it will simultaneously or alternately do work on the first spring 64 (under tension or compression) and the second spring 65 (under compression or tension). This bidirectional spring configuration provides symmetrical restoring force, enhances the dynamic stability of the entire anti-vibration base in the vertical direction, and can effectively cope with vibration impacts from different directions, improving the adaptability of the buffer mechanism to complex vibration conditions.

[0053] In one embodiment, such as Figure 1 and 3 As shown, the adjusting plate 4 is a rectangular plate, and four first buffer components 6 are provided. Two first buffer components 6 are provided at each end of the adjusting plate 4 along the first direction, and four connecting pieces 61 are distributed at the four corners of the adjusting plate 4. This design enables the adjusting plate 4 to move as smoothly as possible in the vertical direction, avoiding the guide column 5 from getting stuck or jammed.

[0054] In one embodiment, such as Figures 1 to 4 As shown, the second buffer assembly 7 also includes two fixed seats 73 fixed to the base plate 12. The two fixed seats 73 are spaced apart along the second direction and connected by a crossbar 74. Two sliding seats 75 are slidably mounted on the crossbar 74. The two ends of the shock-absorbing steel plate 72 are connected to the sliding seats 75 along the second direction. An elastic element is provided between the fixed seats 73 and the sliding seats 75. The elastic element pushes the fixed seats 73 and the sliding seats 75 away from each other. The deformation of the shock-absorbing steel plate 72 pushes the sliding seats 75 connected to it, causing the sliding seats 75 to move on the crossbar 74. The sliding seats 75 compress or pull the elastic element located between the sliding seats 75 and the fixed seats 73, using the elastic element to absorb energy and further increase the vibration resistance.

[0055] In this embodiment, the elastic element is a third spring 76, which is sleeved on the crossbar 74. Furthermore, the third spring 76 is connected to both the fixed seat 73 and the sliding seat 75.

[0056] Furthermore, a limiting block 77 is provided at the bottom of the sliding seat 75, and a limiting groove 121 is opened on the base plate 12. The length of the limiting groove 121 extends along the second direction, and the two limiting blocks 77 of the same second buffer component 7 are slidably disposed in the same limiting groove 121. The sliding of the limiting block 77 and the limiting groove 121 generates sliding friction damping. This sliding friction damping, combined with the damping of the third spring 76, can effectively suppress the resonance of the entire anti-vibration base, significantly attenuate residual vibration, especially low-frequency vibration, and form a three-stage vibration reduction. After the first-stage vibration reduction, the second-stage vibration reduction and the third-stage vibration reduction, the vibration energy is absorbed and attenuated step by step. Finally, only a very small part of the vibration is transmitted to the support frame 1 and the mounting surface of the mounting support frame 1 (such as the ground), thereby ensuring that the magnetic levitation pump 100 operates smoothly and effectively isolates the vibration impact of the magnetic levitation pump 100 on the surrounding environment.

[0057] In this embodiment, the shock-absorbing steel plate 72 includes at least two stacked and fixedly connected arc-shaped spring pieces 720. The length of the arc-shaped spring pieces 720 gradually decreases from bottom to top. The two ends of the lowermost arc-shaped spring piece 720 are rotatably connected to the sliding seat 75 via a third rotating shaft 78, and the uppermost arc-shaped spring piece 720 is fixedly connected to the lower surface of the connecting seat 71. The stacked arc-shaped spring pieces 720 ensure that the strength of the entire shock-absorbing steel plate 72 decreases sequentially from the highest point of the arc towards both ends. This guarantees the connection strength between the shock-absorbing steel plate 72 and the connecting seat 71 while optimizing the elastic deformation capacity at both ends of the shock-absorbing steel plate 72. Furthermore, this structure allows the shock-absorbing steel plate 72 to have a strong restoring effect, preventing the elastic restoring of the shock-absorbing steel plate 72 from failing after repeated pressing. Preferably, the shock-absorbing steel plate 72 has four stacked arc-shaped spring pieces 720, and the lower surface of the connecting seat 71 is in contact with the upper surface of the uppermost arc-shaped spring piece 720.

[0058] In this embodiment, the limiting block 77 is an inverted T-shaped plate, and correspondingly, the limiting groove 121 is a T-shaped groove. The T-shaped limiting block 77 and the T-shaped groove limiting groove 121 slide in a slidable fit. On the one hand, this provides precise guidance for the horizontal sliding of the two sliding seats 75, preventing them from deflecting or getting stuck, and ensuring the stability of the vibration reduction process. On the other hand, the sliding friction generated by this fit is the source of frictional damping in the three-stage vibration reduction. The magnitude of this damping can be optimized through material selection and fit tolerances to achieve the best vibration attenuation effect.

[0059] In one embodiment, such as Figure 1 , Figures 6 to 8As shown, the magnetic levitation pump 100 has a base 8 fixed to its bottom. The mounting frame 3 includes a first frame plate 31, a second frame plate 32, a first clamping plate 33, and a second clamping plate 34. Two first frame plates 31 are spaced apart above the storage plate 2. The two first frame plates 31 are parallel and spaced apart along a second direction. Each first frame plate 31 has a column 35 at both ends along the first direction. The end of the column 35 away from the first frame plate 31 is fixedly connected to the storage plate 2. There are two second frame plates 32. The two second frame plates 32 are parallel and spaced apart along the first direction. Each second frame plate 32 has a first clamping plate 33 and a second clamping plate 34. Two first support plates 31 are connected to both ends of plate 32. Two first clamping plates 33 and two second clamping plates 34 are provided. The two ends of the first clamping plates 33 are slidably connected to the first support plates 31, and the second clamping plates 34 are slidably connected to the second support plates 32. The driving component 36 is connected to the first clamping plates 33 and the second clamping plates 34 respectively, so that the two first clamping plates 33 move closer to each other or further away from each other, and the two second clamping plates 34 move closer to each other or further away from each other. The two first clamping plates 33 and the two second clamping plates 34 can simultaneously abut against the four sides of the base 8. By setting four movable clamping plates to clamp the base 8 from four directions, the base 8 and the magnetic levitation pump 100 fixed on the base 8 can be quickly disassembled and fixed.

[0060] In this embodiment, the mounting frame 3 further includes two reinforcing plates 30, which are spaced apart along a first direction, and each reinforcing plate 30 connects two uprights 35. By setting the reinforcing plates 30, the uprights 35, the first frame plate 31, and the second frame plate 32 are connected to form an integral frame structure, thereby increasing the support strength of this frame structure.

[0061] In this embodiment, a first slot 81 is formed on the side of the base 8 abutting against the first clamping plate 33, and a second slot 82 is formed on the side of the base 8 abutting against the second clamping plate 34. A first insert plate 37 protrudes from the first clamping plate 33, and a second insert plate 38 protrudes from the second clamping plate 34. The first insert plate 37 is inserted into the first slot 81, and the second insert plate 38 is inserted into the second slot 82. By setting slots and insert plates, after the four clamping plates abut against the four sides of the base 8, the vertical movement of the base 8 relative to the clamping plates can be restricted by the interlocking slots and insert plates. This structure also eliminates the need for a support structure for the base 8, i.e., the insert plate serves as both a structure to restrict movement and a support structure, reducing the overall weight of the mounting bracket 3.

[0062] In one embodiment, the driving component 36 is connected to the first clamping plate 33 and the second clamping plate 34 via the transmission component 39. The transmission component 39 includes a first gear 391, a second gear 392, a guide rod 393, a first guide cylinder 394, and a second guide cylinder 395. The first gear 391 and the second gear 392 are coaxially rotatably mounted on the shelf 2 via a fourth rotating shaft 396. There are two guide rods 393, which are arranged in parallel and fixed on the shelf 2. Each guide rod 393 has a first guide cylinder 394 slidably mounted on it. The two first guide cylinders 394 have a first tooth structure 3940 on their opposite sides. The two first guide cylinders 394 are respectively Located on both sides of the first gear 391, and with two first tooth structures 3940 meshing with the first gear 391, the driving member 36 is connected to one of the first guide cylinders 394 to drive the first guide cylinder 394 to move along the length direction of the guide rod 393. The second guide cylinder 395 is slidably disposed on the second frame plate 32. A second tooth structure 3950 is provided on one side opposite to the two second guide cylinders 395. The two second guide cylinders 395 are respectively located on both sides of the second gear 392, and the second tooth structure 3950 meshes with the second gear 392. The first guide cylinder 394 is fixedly connected to the first clamping plate 33, and the second guide cylinder 395 is fixedly connected to the second clamping plate 34. By setting gears, guide cylinders and their toothed structures, one drive unit 36 ​​can drive four clamping plates to move simultaneously toward one side of the base 8 or move simultaneously away from the base 8, thereby clamping or releasing the base 8. This reduces the number of drive units 36, lowers costs, and the synchronous movement keeps the base 8 in the center of the shelf 2, preventing the center of gravity of the shelf 2, the base 8 and the magnetic levitation pump 100 from shifting.

[0063] Furthermore, a groove 310 is provided on the side of the first frame plate 31 facing the base 8, and both ends of the first clamping plate 33 can be inserted into the groove 310 and slidably connected with the first frame plate 31 to achieve movement guidance.

[0064] In this embodiment, the two first clamping plates 33 and the two second clamping plates 34 are located on the same horizontal plane, the two second guide cylinders 395 are located on the same horizontal plane, and the two first guide cylinders 394 are located on the same horizontal plane. Vertically, the four clamping plates are at the top, the two second guide cylinders 395 are below the clamping plates, and the two first guide cylinders 394 are below the second guide cylinders 395, with the first guide cylinders 394 spaced apart from the top surface of the shelf 2. Further, two reinforcing plates 30 are fixedly connected to both ends of the guide rod 393, and the driving member 36 is fixed to the outside of one of the reinforcing plates 30.

[0065] Alternatively, the drive unit 36 ​​can be a cylinder, an electric cylinder, or a linear motor. In this embodiment, the drive unit 36 ​​is a cylinder.

[0066] During installation, the magnetic levitation pump 100, connected to its base 8, is stably hoisted onto the top of the mounting frame 3, roughly at the center of the shelf 2. The drive unit 36 ​​is activated, which pushes one of the first guide cylinders 394 to move linearly along the guide rod 393. The first gear 391, meshing with the first tooth structure 3940 on the first guide cylinder 394, rotates. The first gear 391 drives the second gear 392 located above it to rotate synchronously, and simultaneously drives the other first guide cylinder 394 to move linearly. The two first guide cylinders 394 move in opposite directions, thereby bringing the first clamping plate 33 fixed to them closer together. The rotation of the second gear 392 drives the two second guide cylinders 395 to move in opposite directions, thereby bringing the second clamping plate 34 fixed to them closer together. The four clamping plates move synchronously toward the position close to the base 8 until the insert plate on the clamping plate is inserted into the corresponding slot of the base 8. At this time, the magnetic levitation pump 100 and the base 8 are fixed, and the horizontal and vertical degrees of freedom of the magnetic levitation pump 100 are constrained, retaining only the movement in the vibration reduction direction allowed by the design.

[0067] When the magnetic levitation pump 100 is working, the vibration generated by its operation is transmitted to the mounting frame 3 through the base 8, and then to the shelf 2 through the mounting frame 3. The vibration is transmitted to the four guide columns 5 below it through the shelf 2, and then the guide columns 5 transmit the vibration to the adjustment plate 4.

[0068] The up-and-down movement of the adjusting plate 4 is transmitted to each swing rod 62 through the connecting piece 61. The connecting piece 61 slides within the adjusting hole 621 of the swing rod 62, causing the swing rod 62 to swing around its hinge point with the fastening frame 63 (i.e., the first rotating shaft 66), thereby stretching or compressing the first spring 64 and the second spring 65. Through the elastic deformation of the springs, most of the initial vibration energy is absorbed and consumed, completing the first stage (spring lever) vibration reduction. The up-and-down movement of the adjusting plate 4 is simultaneously transmitted to the arc-shaped damping steel plate 72 through the connecting seat 71 fixed to its bottom. The damping steel plate 72 undergoes elastic bending deformation after being subjected to force. This deformation process further dissipates vibration energy and provides effective buffering for impact loads, achieving the second stage (deformation) vibration reduction. The deformation of the damping steel plate 72 pushes the two sliding seats 75 connected to it through the third rotating shaft 78, causing them to slide on the crossbar 74. The sliding of the sliding seats 75 compresses or stretches the third spring located between it and the fixed seat 73. Spring 76 absorbs energy using spring force. At the same time, T-shaped limiting block 77, fixed to the bottom of sliding seat 75, slides in limiting groove 121 of base plate 12, generating controllable sliding friction damping. This combination mechanism of spring damping and sliding friction effectively suppresses system resonance and significantly attenuates residual vibration, especially low-frequency vibration, completing three-stage vibration reduction. Through the above three-stage series vibration reduction process, vibration energy is absorbed and attenuated step by step, and finally only a very small part of residual vibration is transmitted to support frame 1 and mounting surface, thereby ensuring that the magnetic levitation pump 100 operates extremely smoothly and effectively isolates its influence on the surrounding environment. When the magnetic levitation pump 100 needs to be disassembled, control drive component 36 pulls the first guide cylinder 394 in the opposite direction. Through the reverse movement of the above gear and tooth structure transmission system, drive the four clamping plates to move outward synchronously, so that the insert plate is removed from the slot of base 8, thereby unlocking and easily removing the magnetic levitation pump 100 and base 8.
