Description

Technical Field

[0001] This utility model relates to the field of pump technology, specifically a low-noise pump. Background Technology

[0002] Pumps, as indispensable core equipment for fluid transportation in modern industry and daily life, efficiently convert the mechanical energy output from a prime mover or other external energy into the kinetic and potential energy of the liquid through precise mechanical transmission design, achieving directional fluid transportation and pressure enhancement. Their working principles encompass various technical approaches, including centrifugal force drive, volumetric change, and jet drainage, adapting to different fluid characteristics and operating conditions. Pumps are mainly used to transport liquids such as water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids, and are widely used in industrial manufacturing, energy extraction, construction engineering, and environmental water treatment.

[0003] Chinese Patent Publication No. CN 216742154U discloses a high-efficiency, low-noise pump. The impeller within the pump has a drainage groove formed by a first inner sidewall, a second inner sidewall, and the impeller edge, all arranged opposite each other. The first and second inner sidewalls are sequentially arranged along the impeller's rotation trajectory. The second inner sidewall, from its connection point with the impeller to its end away from the impeller, has a first concave arc surface and a second convex arc surface, with the first and second arc surfaces tangentially connected. This technical solution can improve the pump's conveying efficiency and reduce the noise generated during operation.

[0004] In existing technologies, noise reduction in the use of a high-efficiency, low-noise pump relies solely on optimizing fluid dynamics through a special impeller structure. This approach fails to effectively block vibration transmission paths and is ill-suited to address noise issues caused by mechanical vibration. Furthermore, when operating conditions change, it cannot guarantee that the pump will always be in optimal vibration and noise reduction mode, thus affecting equipment stability and noise control. Therefore, we have made improvements and proposed a low-noise pump. Utility Model Content

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1-3, a low-noise pump, comprising a base 1, a connecting seat 2 disposed above the base 1, a pump body 3 movably connected between the base 1 and the connecting seat 2, multiple shock-absorbing pads 4 and sealing rings 5 ​​embedded on the sides of the base 1 and the connecting seat 2 that are close to each other, worm gears 7 rotatably connected inside the connecting seat 2 and on corresponding sides of the pump body 3, multiple worm wheels 8 meshing on the outer sides of the two worm gears 7, threaded rods 9 fixedly installed at the bottom of the multiple worm wheels 8, the multiple worm wheels 8 and the threaded rods 9 being rotatably connected to the connecting seat 2, and the multiple threaded rods 9 being rotatably connected to the connecting seat 2. The outer side of the rod 9 is threaded with a sliding plate 10. Multiple sliding plates 10 pass through the bottom of the connecting seat 2 and are slidably connected to it. A damper 11 is provided on the top of the base 1 and at the bottom of the multiple sliding plates 10. Multiple dampers 11 are inserted into the interior of the base 1 and fixedly connected to it. The output end of the damper 11 is fixedly connected to the sliding plate 10. Two shock-absorbing springs 12 are provided on the top of the base 1 and on the corresponding sides of the multiple dampers 11. The two ends of the multiple shock-absorbing springs 12 are fixedly connected to the base 1 and the sliding plate 10 respectively.

[0031] In this embodiment of the invention, the vibration generated by the pump body 3 during operation is initially buffered by the shock-absorbing pad 4 embedded between the base 1 and the connecting seat 2. Simultaneously, the slide plate 10 can move up and down under the drive of the threaded rod 9. When the vibration of the pump body 3 is transmitted to the slide plate 10, the damper 11 and the shock-absorbing spring 12 work together. The damper 11 absorbs the vibration energy, and the shock-absorbing spring 12 further buffers and rebounds, reducing the transmission of vibration to the base 1 and the connecting seat 2, thereby reducing noise generation.

[0032] In this embodiment of the utility model, the vibration and noise generated by the pump body 3 during operation are effectively reduced, providing a quiet working environment for operators, while reducing the damage of vibration to the pump body 3 and other components, and extending the service life of the pump.

[0033] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -4. As a preferred embodiment of the present invention, guide rods 13 are provided at the bottom of the connecting seat 2 and inside the multiple slide plates 10. The multiple guide rods 13 are fixedly connected to the connecting seat 2 and pass through the slide plates 10 and are fixedly connected to them.

[0034] A servo motor 15 is fixedly installed inside the connector 2. Two connecting rods 14 are rotatably connected inside the connector 2, and the connecting rods 14 are fixedly connected to the worm gear 8. A synchronous pulley is fixedly installed on the top of each of the two connecting rods 14, and the synchronous pulley is rotatably connected to the connector 2. A synchronous belt is connected to the outer side of the two synchronous pulleys. The output end of the servo motor 15 is fixedly connected to one of the synchronous pulleys.

[0035] Both sides of the top of the base 1 are fixedly installed with plugs 6, and both plugs 6 are inserted into the interior of the connecting seat 2 and slidably connected to it.

[0036] The connecting seat 2 has a connecting structure inside and on one side of the two plug blocks 6. The connection includes a plug rod 17, which is slidably connected to the connecting seat 2 and the plug blocks 6. A fixing plate 16 is fixedly installed on one side of the plug rod 17. The fixing plate 16 is slidably connected to the connecting seat 2. Multiple compression springs 18 are fixedly installed on the side of the fixing plate 16 away from the plug blocks 6. The ends of the multiple compression springs 18 away from the fixing plate 16 are all fixedly connected to the connecting seat 2. A push plate 19 is fixedly installed on one side of the fixing plate 16. The push plate 19 passes through one side of the connecting seat 2 and is slidably connected to it.

[0037] The connector 2 is equipped with a control module 22. The control module 22 is electrically connected to the connector 2, the servo motor 15 and the pressure sensor 20. The connector 2 has multiple through holes. Dustproof nets 21 are fixedly installed inside the connector 2 and inside the multiple through holes.

[0038] In this embodiment of the invention, after the servo motor 15 is started, it drives the connecting rod 14 to rotate through the synchronous pulley and synchronous belt, which in turn causes the worm 7 to rotate. The worm wheel 8, which meshes with the worm 7, rotates accordingly, driving the threaded rod 9 to rotate. This causes the slide plate 10 to move up and down under the guidance of the guide rod 13, thereby adjusting the position of the slide plate 10 and changing the working state of the damper 11 and the shock absorption spring 12. This allows for flexible adjustment of the shock absorption effect according to different working states and vibration conditions of the pump body 3, improving the applicability and effectiveness of the shock absorption system and further optimizing the noise reduction performance.

[0039] When installing the pump body 3, simply align the plug 6 on the top of the base 1 with the insertion connector 2, push the push plate 19 to move the plug rod 17 away from the plug 6, and at the same time, the plug rod 17 will automatically insert into the plug 6 under the action of the compression spring 18, which can quickly complete the connection, reduce installation and maintenance time, improve the work efficiency of equipment maintenance, and reduce labor costs.

[0040] The through holes on the connector 2 are used for ventilation and heat dissipation. The dustproof mesh 21 inside the through holes can block external dust and debris from entering the connector 2, preventing dust and other objects from entering and affecting the normal operation of the internal mechanical parts.

[0041] The control module 22 is electrically connected to the peripheral controller. The control module 22 sends corresponding electrical signals to the servo motor 15 according to the instructions, controlling the start, stop and speed of the servo motor 15. The pressure sensor 20 monitors the pressure of the pump in real time and feeds back the pressure data to the control module 22 in the form of electrical signals. After processing the data, the control module 22 feeds back the working status information of the pump to the peripheral controller through the data transmission line, so that the operator can understand the operation of the pump in real time.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
