Description

Technical Field

[0001] This utility model relates to the field of pipeline testing technology, specifically a water system pipeline testing platform with a fixed pure water pipe structure. Background Technology

[0002] In fields with extremely high water quality requirements, such as semiconductor manufacturing, medical and pharmaceutical industries, and nuclear power, water system pipeline test platforms are core equipment for studying the performance of pure water pipelines and optimizing the design of delivery systems.

[0003] In existing water system pipeline experimental platforms, pure water pipelines are often fixed using a rigid structure, with the pipes directly mounted to the frame. When the water pump operates, the strong vibrations generated are transmitted along the pipeline, causing pipe joints to loosen, seals to fail, and even fatigue fractures. For example, in semiconductor ultrapure water experiments, the vibration of rigidly fixed pipelines increases the amount of metal ion leaching, severely affecting the accuracy and reliability of experimental data. Therefore, this invention proposes a water system pipeline experimental platform with a fixed pure water pipe structure to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, such as rigid pipe fixing, poor vibration damping, and inconvenient adjustment in experimental platforms, a multi-stage buffering mechanism for water pump vibration and flexible adjustment of pipe position are achieved by setting up a bellows, a slider buffer mechanism, and a threaded rod adjustment mechanism. This avoids pipe loosening, data inaccuracy, and frequent disassembly and assembly, thereby improving experimental stability and operational efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame, with a pure water tank and a water pump fixedly connected to the bottom of the frame. The pure water tank is connected to the water pump inlet via a connecting pipe. A water pipe is installed inside the frame, with corrugated pipes installed at both ends of the water pipe. One set of corrugated pipes is connected to the water pump outlet, and a quick-release connector is fixedly connected to the end of the other corrugated pipe. Two sets of sliders are slidably connected inside the frame, with a buffer mechanism installed inside each slider. An adjustment mechanism is installed inside the frame.

[0008] The buffer mechanism is used to reduce the impact of water pump vibration on the water pipe;

[0009] The adjustment mechanism is used to adjust the position of the two sets of sliders.

[0010] Preferably, the buffer mechanism includes a buffer groove formed on the outer wall of the slider, a connecting rod fixedly connected to the bottom of the buffer groove, a sliding plate slidably connected to the outer wall of the connecting rod, two sets of clamping plates installed on the outside of the sliding plate, the two sets of clamping plates being connected to each other by screws, one set of clamping plates being fixedly connected to the sliding plate, and the water pipe being clamped in the two sets of clamping plates.

[0011] Preferably, a spring is sleeved on the outer wall of the connecting rod, one end of the spring is fixedly connected to the bottom of the buffer groove, the other end of the spring is fixedly connected to the lower end face of the slide plate, and both outer walls of the slide plate are in contact with the inner wall of the buffer groove.

[0012] Preferably, the adjustment mechanism includes two sets of threaded rods rotatably connected to the bottom of the frame, two sets of sliding grooves are provided in the frame, the two sets of sliders are slidably connected in the two sets of sliding grooves respectively, and the inner walls of the two sets of sliding grooves are provided with connecting grooves. A moving block is threadedly connected to the threaded section of the threaded rod, and the moving block is fixedly connected to the adjacent slider through a connecting rod. The slider slides in the connecting groove.

[0013] Preferably, multiple sets of limiting rods are fixedly connected to the bottom of the frame, and the moving block is slidably connected to the outer wall of the adjacent limiting rods.

[0014] Preferably, the inner walls of both sets of card plates are equipped with cushioning pads.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a water system pipeline experimental platform with a fixed pure water pipe structure, which has the following beneficial effects:

[0017] 1. By installing corrugated pipes at both ends of the water pipe, in conjunction with the buffer mechanism inside the slider, the vibration and water hammer impact generated by the operation of the water pump can be absorbed in all directions. The buffer structure composed of springs, sliding plates and clamping plates can provide secondary buffering for the vibration transmitted to the water pipe, avoiding the risk of loosening of pipe joints, failure of seals or fatigue fracture caused by vibration. It effectively reduces the risk of water pollution such as metal ion leaching, ensures stable water flow during the experiment, and provides a stable and reliable experimental environment for fields with extremely high water quality requirements such as semiconductor manufacturing and medical pharmaceutical, ensuring the accuracy of experimental data.

[0018] 2. By cooperating with the threaded rod, the moving block and the slider, the position of the water pipe can be precisely adjusted. When the experimental requirements change and it is necessary to replace the pure water pipe of different lengths or adjust the pipe layout, the position of the slider can be changed by rotating the threaded rod, so as to quickly adapt to different experimental conditions.

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] This utility model provides a technical solution for a water system pipeline experimental platform with a fixed pure water pipe structure:

[0026] Please see Figure 1-4 An experimental platform for a water system pipeline with a fixed pure water pipe structure includes a frame 1. A pure water tank 2 and a water pump 3 are fixedly connected to the bottom of the frame 1. The pure water tank 2 is connected to the inlet of the water pump 3 through a connecting pipe. A water pipe 4 is installed inside the frame 1. Corrugated pipes 5 are installed at both ends of the water pipe 4. One set of corrugated pipes 5 is connected to the outlet of the water pump 3, and a quick-release connector 6 is fixedly connected to the end of the other corrugated pipe 5. Two sets of sliders 7 are slidably connected inside the frame 1. A buffer mechanism is provided inside the sliders 7. An adjustment mechanism is installed inside the frame 1.

[0027] The buffer mechanism is used to reduce the impact of the vibration of the water pump 3 on the water pipe 4;

[0028] The adjustment mechanism is used to adjust the position of the two sets of sliders 7;

[0029] Furthermore, by installing corrugated pipes 5 at both ends of the water pipe 4, the mechanical vibration and water hammer impact generated by the start-up or operation of the water pump 3 can be absorbed, preventing the vibration from being rigidly transmitted along the water pipe 4.

[0030] The buffer mechanism includes a buffer groove 15 opened on the outer wall of the slider 7. A connecting rod 14 is fixedly connected to the bottom of the buffer groove 15. A sliding plate 16 is slidably connected to the outer wall of the connecting rod 14. Two sets of clamping plates 18 are installed on the outside of the sliding plate 16. The two sets of clamping plates 18 are connected to each other by screws. One set of clamping plates 18 is fixedly connected to the sliding plate 16. The water pipe 4 is engaged in the two sets of clamping plates 18.

[0031] Furthermore, the sliding structure, combined with the clamping assembly between the slide plate 16 and the clamping plate 18, can not only alleviate the direct effect of water pump vibration, but also provide a certain degree of freedom when the water pipe 4 undergoes slight displacement, thereby avoiding forced pulling and deformation of the pipe body.

[0032] A spring 17 is sleeved on the outer wall of the connecting rod 14. One end of the spring 17 is fixedly connected to the bottom of the buffer groove 15, and the other end of the spring 17 is fixedly connected to the lower end face of the slide plate 16. Both outer walls of the slide plate 16 are in contact with the inner wall of the buffer groove 15.

[0033] Furthermore, the spring 17 provides controllable elastic support, enabling the slide plate 16 to have a buffer stroke under vibration, reducing the transmission of pulse energy during the operation of the water pump 3, and effectively controlling the micro-deformation of the pure water pipe 4 caused by external force.

[0034] The adjustment mechanism includes two sets of threaded rods 11 rotatably connected to the bottom of the frame 1. Two sets of sliding grooves 8 are provided in the frame 1. Two sets of sliders 7 are slidably connected in the two sets of sliding grooves 8 respectively. A connecting groove 9 is provided on the inner wall of each set of sliding grooves 8. A moving block 13 is threadedly connected to the threaded section of the threaded rod 11. The moving block 13 is fixedly connected to the adjacent slider 7 through a connecting rod. The slider 7 slides in the connecting groove 9.

[0035] Furthermore, the adjustment mechanism can achieve precise fine-tuning of the slider 7 along the slide groove 8 by rotating the threaded rod 11, thereby controlling the spatial position of the water pipe 4 within the frame 1.

[0036] The bottom of the frame 1 is fixedly connected to multiple sets of limiting rods 12, and the moving block 13 is slidably connected to the outer wall of the adjacent limiting rods 12. The inner walls of the two sets of clamping plates 18 are all equipped with buffer pads.

[0037] Furthermore, the buffer pad provides flexible support when clamping the water pipe 4, preventing the pipe from directly contacting the rigid clamping plate 18 and causing wear, indentation, or deformation.

[0038] In practical use, the working principle of this utility model is as follows:

[0039] When conducting pure water flow experiments using this water system pipeline experimental platform, the operator first starts the water pump 3. Pure water from the pure water tank 2 is drawn in through the connecting pipe and output by the water pump 3 into the water pipe 4 installed in the frame 1. Because the water pump generates strong vibrations and periodic pulse pressure during operation, if it acts directly on the rigidly installed water pipe 4, it can easily cause the pipe to loosen, the joints to become poorly sealed, or even fatigue damage.

[0040] To address this, the platform is designed with corrugated pipes 5 at both ends of the water pipe 4 to initially absorb vibrations and water hammer effects from the outlet of the water pump 3. The corrugated pipes 5 have a certain degree of flexibility and compression stroke, which can effectively isolate the rigid connection between the water pump output end and the fixed structure, prevent energy from being directly transmitted to the main body of the water pipe, and protect the water pipe 4 to maintain structural stability under high-frequency vibration.

[0041] Meanwhile, the water pipe 4 is clamped and fixed in the buffer mechanism inside the two sets of sliders 7. When the water pump is operating, the residual vibration transmitted to the water pipe 4 is transmitted to the connecting rod 14 and spring 17 structure via the clamping plate 18 and the sliding plate 16. The spring 17 undergoes controllable deformation after being compressed, thereby playing a further role in buffering and shock absorption. Since the two sides of the sliding plate 16 are in contact with the inner wall of the buffer groove 15, it ensures that the direction is restricted and the movement is smooth during the sliding process, which can effectively avoid lateral shaking and knocking caused by vibration.

[0042] During the experiment, if different types of pipes need to be adapted, the operator can rotate the threaded rod 11 to drive the moving block 13 to slide along the limiting rod 12 and the connecting groove 9, indirectly driving the slider 7 to move in the sliding groove 8, thereby changing the installation position of the water pipe 4. In addition, the buffer pad provided on the inner wall of the clamping plate 18 can provide flexible coverage during the clamping of the water pipe 4, reducing the stress concentration effect on the water pipe caused by the clamping force concentrated at a single point.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
