Description

Technical Field

[0001] This utility model relates to the technical field of pump equipment support structure, and in particular to a shock-resistant and buffer support structure for a liquid electromagnetic pump body. Background Technology

[0002] Liquid electromagnetic pumps, as devices with no moving parts that use electromagnetic force to drive the flow of liquid metal, have key applications in nuclear energy, fusion devices, and advanced energy systems. However, during operation, the electromagnetic field inside the pump undergoes periodic changes, causing the Lorentz force to fluctuate over time. Furthermore, as the liquid metal flows within the pump chamber, uneven distribution of electromagnetic force or design flaws in the flow channel can lead to pressure pulsations or even localized cavitation. These fluid dynamic instabilities can be transmitted to the pump body, thereby inducing mechanical vibrations in the pump structure. Traditional pump body supports often use rigid brackets or simple rubber pads. While rigid supports offer accurate positioning, they lack sufficient vibration damping. Ordinary elastic materials are prone to aging and failure in high-temperature, high-radiation, or corrosive liquid metal environments.

[0003] Therefore, it is necessary to design a shock-resistant and buffer support structure for the pump body of a liquid electromagnetic pump to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of insufficient shock absorption and poor environmental adaptability, this utility model provides a shock-resistant buffer support structure for a liquid electromagnetic pump body.

[0005] The technical solution of this utility model is: a shock-resistant and buffer support structure for a liquid electromagnetic pump body, including an electromagnetic pump, a mounting base, a sliding frame, a sliding frame and a first spring. The mounting base is fixedly connected to the lower part of the electromagnetic pump, and four sliding frames are fixedly connected to the bottom of the mounting base. A sliding frame is slidably connected between the middle parts of the four sliding frames. A first spring is sleeved on the upper part of each of the four sliding frames, and the two ends of the four first springs are respectively connected to the sliding frame and the mounting base.

[0006] In one embodiment, the system further includes a support frame, a sliding block, and a rotating frame. Four support frames are fixedly connected to the top of the inner side of the sliding frame, and sliding blocks are slidably connected to each of the four support frames. A rotating frame is rotatably connected between the corresponding sliding block and the lower part of the corresponding sliding frame.

[0007] In one embodiment, a second spring is also included, with the corresponding sliding block connected to the corresponding support frame via the second spring at the end furthest from the center, and the corresponding second spring being sleeved on the corresponding support frame.

[0008] In one embodiment, a damper is also included, with dampers installed on both the left and right sides between the bottom of the mounting base and the bottom of the inner side of the sliding frame.

[0009] In one embodiment, a base plate is also included, and a support frame is slidably sleeved on the outside of the sliding frame, with the base plate fixedly connected to the bottom of the support frame.

[0010] In one embodiment, the system further includes guide rods and third springs. A guide rod is provided between the bottom of the sliding frame and the top of the base plate. All four guide rods are fixedly connected to the base plate and slidably connected to the sliding frame. Each of the four guide rods is fitted with a third spring, and both ends of the four third springs are respectively connected to the base plate and the sliding frame.

[0011] The beneficial effects are: 1. This utility model, through the cooperation of the mounting base, sliding frame and the first spring, constitutes a preliminary vibration reduction system, which can effectively absorb and buffer the main vibration energy generated by the electromagnetic pump and reduce the initial vibration amplitude.

[0012] 2. This utility model, through the synergistic action of the support frame, sliding block, rotating frame and second spring, converts part of the longitudinal vibration energy into lateral motion and dissipates the energy, thereby enhancing the system's adaptability and buffering ability to multi-directional and complex vibration modes and achieving second-stage vibration reduction.

[0013] 3. This utility model provides significant viscous damping force through a damper installed between the mounting base and the sliding frame, which can rapidly attenuate vibration amplitude, effectively suppress resonance and low-frequency large-amplitude vibration, and improve system stability.

[0014] 4. This utility model, through the support and vibration isolation design of the support frame, base plate, guide rod and third spring, effectively isolates the transmission of vibration to the foundation structure and prevents vibration from spreading while ensuring the vertical movement stability of the pump body.

Detailed Implementation

[0020] Example: A shock-resistant and buffer support structure for a liquid electromagnetic pump body, such as... Figures 1-4 As shown, it includes an electromagnetic pump 1, a mounting base 2, a sliding bracket 5, a sliding frame 4, and a first spring 6. The lower part of the electromagnetic pump 1 is fixedly connected to the mounting base 2 by bolts. Four sliding brackets 5 are fixedly connected to the bottom of the mounting base 2. The sliding frame 4 is slidably connected between the middle parts of the four sliding brackets 5. The upper part of each of the four sliding brackets 5 is fitted with a first spring 6. The two ends of the four first springs 6 are respectively connected to the sliding frame 4 and the mounting base 2.

[0021] like Figure 2 and Figure 3 As shown, it also includes a support frame 8, a sliding block 10 and a rotating frame 7. Four support frames 8 are fixedly connected to the top of the inner side of the sliding frame 4. Sliding blocks 10 are slidably connected to each of the four support frames 8. The corresponding sliding block 10 is rotatably connected to the lower part of the corresponding sliding frame 5 by a rotating frame 7.

[0022] like Figure 3 As shown, it also includes a second spring 9. The corresponding sliding block 10 is connected to the corresponding support frame 8 by the second spring 9 at the end away from the center. The corresponding second spring 9 is sleeved on the corresponding support frame 8.

[0023] like Figure 2 As shown, it also includes a damper 11, with dampers 11 installed on both the left and right sides between the bottom of the mounting base 2 and the inner bottom of the sliding frame 4.

[0024] like Figure 2 and Figure 4 As shown, it also includes a base plate 12, and a support frame 3 is slidably sleeved on the outside of the sliding frame 4. The bottom of the support frame 3 is fixedly connected to the base plate 12 by bolts.

[0025] like Figure 2 and Figure 4 As shown, it also includes guide rods 13 and third springs 14. A guide rod 13 is provided between the bottom of the sliding frame 4 and the top of the base plate 12. All four guide rods 13 are fixedly connected to the base plate 12 and slidably connected to the sliding frame 4. A third spring 14 is sleeved on each of the four guide rods 13. The two ends of the four third springs 14 are respectively connected to the base plate 12 and the sliding frame 4.

[0026] When this device is needed to provide effective vibration damping support for the liquid electromagnetic pump 1, it is first installed in a fixed position. When the electromagnetic pump 1 vibrates, the vibration energy is first transmitted to the four sliding frames 5 below it through the mounting base 2. The sliding frames 5 can slide axially under the constraint of the sliding frame 4 and compress or stretch the first spring 6 sleeved on its upper part. The first spring 6 absorbs and buffers the main vibration energy through its own elastic deformation, and performs initial vibration damping. At the same time, the vibration drives the sliding frame 4 and the support frame 8 to move, and then transmits the force to the sliding block 10 through the rotating frame 7, so that it slides on the support frame 8 and stretches or compresses the second spring 9. The second spring 9 provides additional elastic restoring force, which enhances the system's adaptability to complex vibration modes and further buffers the vibration energy. At the same time, the rotating frame 7 will produce an angle change during the movement. Through the lever action of the rotating frame 7, part of the longitudinal vibration energy is converted into the lateral movement of the sliding block 10. The energy is dissipated through friction and the deformation and restoring of the second spring 9. Moreover, the damper 11 between the mounting base 2 and the sliding frame 4 provides additional damping force, which quickly attenuates the vibration amplitude.

[0027] Finally, the vibration, after multiple stages of buffering and damping, is transmitted to the support frame 3 and the base plate 12 on the outside of the sliding frame 4. The sliding frame 4 and the base plate 12 maintain vertical stability through the guide rod 13, and the third spring 14 sleeved on the guide rod 13 provides elastic support and vibration isolation, ensuring the stable positioning of the entire pump body structure, while isolating the transmission of vibration to the foundation structure.
