Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump motor technology, and in particular to a noise-reducing submersible pump motor. Background Technology
[0002] The submersible pump motor is the core power component of a submersible pump, consisting of a stator, rotor, housing, sealing structure, and cooling system. The entire motor must have good waterproof sealing performance to adapt to underwater and humid environments. This type of motor uses asynchronous motors or permanent magnet synchronous motors, which drive the submersible pump impeller to rotate through the efficient conversion of electrical energy and mechanical energy, realizing the extraction, transportation, and circulation of liquids. It is used in agricultural irrigation, industrial water circulation, and domestic water supply scenarios, and is an indispensable power device in modern fluid transportation systems.
[0003] The core function of a submersible pump motor is to provide stable and efficient power output for the submersible pump, ensuring precise liquid delivery under different operating conditions. It drives the submersible pump to complete farmland irrigation and pond water exchange operations, ensuring the water supply needed for crop growth. It can also be used for urban sewage treatment, rainwater discharge, and pipeline pressurization, maintaining the stable operation of the urban water circulation system. In industrial scenarios, it can provide power for cooling systems and wastewater treatment equipment, helping to ensure the continuity of industrial production processes. It can also meet the lightweight needs of daily water supply. Its performance directly determines the operating efficiency, service life, and applicable range of the submersible pump.
[0004] Currently, mainstream submersible pump motors on the market suffer from high noise levels and poor noise reduction during operation. The electromagnetic vibration between the stator and rotor, the mechanical friction vibration generated by the bearing rotation, and the aerodynamic noise generated by the airflow disturbance inside the motor are transmitted outward through the casing and end cover structure. Especially when operating underwater, the water will further aggravate the propagation and diffusion of noise. Existing noise reduction designs for submersible pump motors are mostly concentrated on simple sound insulation material wrapping, which not only causes auditory interference to operators and surrounding residents, but also accelerates the wear of motor components and reduces the reliability and service life of the equipment due to long-term high noise operation.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the device is equipped with a noise isolation device, which can directly act on the noise source and propagation path of the motor during operation. When the stator and rotor of the motor generate electromagnetic vibration, and the bearings rotate to generate mechanical friction vibration, the noise isolation device can absorb and attenuate the vibration energy through its own buffering and energy absorption characteristics, so as to prevent the vibration from being directly transmitted to the casing. For the aerodynamic noise generated by the airflow disturbance inside the motor, the noise isolation device can form a multi-layer sound barrier, which solves the problem of uncontrolled noise propagation in traditional motors, reduces the damage of noise to the hearing system of operators, and improves the comfort and environmental protection of the equipment.
[0024] 2. In this utility model, a vacuum pump is provided on the right side of the device, which can perform vacuum treatment on the internal cavity of the pump body before the motor is started, completely removing any residual air and creating a stable negative pressure environment inside the pump body. Traditional submersible pump motors are prone to residual air inside due to assembly gaps and aging of the sealing structure. This air will cause airflow disturbance with the impeller rotation when the motor is running, thereby aggravating noise. This device eliminates residual air inside the pump body through the vacuum pump, avoiding the generation of airflow disturbance noise and ensuring that the pump body always maintains a low air pressure state.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a noise-reducing submersible pump motor, including a built-in water pump 1, a vacuum pump 2 is provided on the right side of the built-in water pump 1, a buffer mechanism 3 is provided on the outside of the built-in water pump 1, the buffer mechanism 3 is used to reduce the vibration noise generated by the water pump, and a vacuum mechanism 4 is provided on the left side of the vacuum pump 2, the vacuum mechanism 4 is used to vent the air inside the water pump.
[0034] The buffer mechanism 3 includes a bottom connector 31. The top of the bottom connector 31 is fixedly connected to the bottom of the built-in water pump 1, and the rear side of the bottom connector 31 is fixedly connected to the rear side of the inner wall of the buffer layer 32. A water inlet assembly 33 is provided at the bottom of the bottom connector 31. A fixing ring 34 is fixedly connected to the outer wall of the buffer layer 32. A bottom shell 35 is fixedly connected to the bottom of the fixing ring 34. A handle assembly 36 is provided at the top of the fixing ring 34. A water outlet assembly 37 is provided at the rear side of the top of the fixing ring 34. A plurality of external reinforcing ribs 38 are fixedly connected to the outer wall of the bottom shell 35. A reinforcing rib fixing member 39 is fixedly connected to the top of each of the plurality of external reinforcing ribs 38.
[0035] Specifically, the bottom connector 31 in the buffer mechanism 3 transmits the bottom vibration of the built-in water pump 1 to the buffer layer 32. The buffer layer 32 buffers the vibration impact through its own deformation, reducing the vibration transmission between the built-in water pump 1 and the bottom shell 35. The fixed connection between the rear side of the bottom connector 31 and the rear side of the inner wall of the buffer layer 32 ensures that the buffer layer 32 can stably bear the vibration transmitted by the built-in water pump 1, avoiding the vibration from causing component displacement and affecting the noise reduction effect.
[0036] When the device is being transported, the handle assembly 36 at the top of the fixed ring 34 disperses the external force to the buffer layer 32 through the connection between the fixed ring 34 and the buffer layer 32, preventing the external force from directly acting on the built-in water pump 1 and affecting the stability of its internal noise generation structure. Multiple external reinforcing ribs 38 on the outer wall of the bottom shell 35 are fixedly connected to the fixed ring 34 through the reinforcing rib fasteners 39, which enhances the connection strength between the bottom shell 35 and the fixed ring 34. This allows the bottom shell 35 to provide stable support for the entire buffer structure during the buffering vibration process, preventing the buffering effect of the buffering mechanism 3 from weakening due to the deformation of the bottom shell 35.
[0037] When liquid enters the built-in water pump 1, the water inlet component 33 at the bottom of the buffer mechanism 3 is connected to the built-in water pump 1 through the bottom connector 31, so that the noise generated by the liquid flow is transmitted to the buffer layer 32 for buffering. When liquid is discharged, the water outlet component 37 at the top rear side of the fixed ring 34 is fixedly connected to the fixed ring 34 to ensure that the impact force of the discharged liquid will not directly act on the built-in water pump 1, further reducing the additional noise caused by the liquid flow. Through the transmission, buffering and weakening of vibration and noise, the various structures achieve effective control of the operating noise of the built-in water pump 1.
[0038] Reference Figure 1 , Figure 4 and Figure 5 The vacuum mechanism 4 includes a side connector 41. The right side of the side connector 41 is fixedly connected to the left side of the vacuum pump 2. The four corners of the right side of the side connector 41 are threaded with fixing bolts 42. The top of the vacuum pump 2 is fixedly connected with a vacuum tube 43. The bottom of the side connector 41 is fixedly connected with a bottom outer shell 44. The bottom of the bottom outer shell 44 is fixedly connected with a bottom connecting shell 45. The top of the bottom connecting shell 45 is provided with a shock-absorbing component 46. The front side of the bottom connecting shell 45 is provided with a water inlet component 47. The bottom of the bottom connecting shell 45 is provided with a bottom support component 48.
[0039] Specifically, the side connector 41 in the vacuum mechanism 4 is fixedly connected to the left side of the vacuum pump 2 on its right side. This connection allows the side connector 41 to provide lateral structural support for the vacuum pump 2, and at the same time, it serves as a transitional component between the vacuum pump 2 and other parts of the vacuum mechanism 4, realizing force transmission and position fixation between the vacuum pump 2 and subsequent parts. The fixing bolts 42 at the four corners on the right side of the side connector 41 are installed on the side connector 41 by threaded connection. The fixing bolts 42 can enhance the tightness of the connection between the side connector 41 and the vacuum pump 2, and prevent relative displacement between the side connector 41 and the vacuum pump 2 when the vacuum pump 2 vibrates during operation, ensuring the stability of the connection between the two, and thus maintaining the overall reliability of the entire vacuum mechanism 4 and vacuum pump 2 combined structure.
[0040] The vacuum tube 43, which is fixedly connected to the top of the vacuum pump 2, serves as a key channel component for the vacuum pump 2 to achieve its vacuum extraction function. One end of the tube is connected to the internal cavity of the vacuum pump 2, and the other end can be connected to the equipment to be vacuumed according to actual operational needs. Through the channel function of the vacuum tube 43, the vacuum pump 2 can draw in and expel the gas from the area to be vacuumed, thereby creating a vacuum state in that area. The bottom shell 44, which is fixedly connected to the bottom of the side connector 41, serves as the basic support component of the bottom structure of the vacuum mechanism 4. Its top is connected to the side connector 41, and its bottom is connected to the bottom connecting shell 45. Through the structural frame function of the bottom shell 44, it provides an installation carrier and position positioning for the bottom connecting shell 45 and other components installed on the bottom connecting shell 45. At the same time, the bottom shell 44 can provide a certain degree of protection for the cables and pipe components inside, preventing external environmental factors from damaging these components.
[0041] The bottom connecting shell 45, which is fixedly connected to the bottom of the bottom outer shell 44, serves as a connecting transition component between the bottom outer shell 44 and the shock-absorbing component 46, the water inlet component 47, and the bottom support component 48. Its top is connected to the bottom outer shell 44, the shock-absorbing component 46 is installed on the top, the water inlet component 47 is set on the front side, and the bottom support component 48 is set on the bottom. Through the structural design of the bottom connecting shell 45, the positional association and force transmission between the shock-absorbing component 46, the water inlet component 47, the bottom support component 48 and the bottom outer shell 44 are realized, so that each component can form a coordinated overall structure around the bottom connecting shell 45. When the vacuum pump 2 generates vibration during operation and transmits it to the bottom connecting shell 45 through the side connector 41 and the bottom outer shell 44, the shock-absorbing component 46 set on the top of the bottom connecting shell 45 can absorb part of the vibration energy through its own structural deformation, reduce the intensity of vibration transmission to other components below the bottom connecting shell 45, thereby reducing the noise and structural wear of the entire vacuum mechanism 4 and its connected related equipment due to vibration.
[0042] The water inlet assembly 47 is provided on the front side of the bottom connecting shell 45. One end of the assembly is connected to an external water source, and the other end can communicate with the inside of the bottom connecting shell 45 according to the functional requirements of the vacuum mechanism 4. When the vacuum pump 2 needs to be cooled or cleaned during operation, the water inlet assembly 47 can introduce external liquid to the designated location to provide liquid medium support for the relevant operations of the vacuum mechanism 4 and ensure that the vacuum pump 2 operates in a suitable working environment.
[0043] Reference Figure 1 and Figure 2 The water inlet assembly 33 includes a water inlet pipe 331, the top of which is fixedly connected to the bottom of the bottom connector 31, and a bottom water inlet 332 is fixedly connected to the bottom of the water inlet pipe 331. The water inlet assembly 33 also includes a lower fixing bracket 361, the bottom of which is fixedly connected to the top of the fixing ring 34, and an upper handle 362 is fixedly connected to the top of the lower fixing bracket 361. The water outlet assembly 37 includes an upper connector 371, the bottom of which is located at the top of the fixing ring 34, and a water outlet pipe 372 is fixedly connected to the top of the upper connector 371. (Shock absorption...) Component 46 includes a damping hole 461, the bottom of which is opened on the top of the bottom connecting shell 45. A damping slide rod 462 is slidably connected to the outer wall of the damping hole 461. The water inlet component 47 includes a bottom connecting piece 471, the rear side of which is fixedly connected to the front side of the bottom connecting shell 45. A water inlet ring 472 is fixedly connected to the top of the bottom connecting piece 471. The bottom support component 48 includes a bottom support piece 481, the bottom of which is fixedly connected to the bottom of the bottom connecting shell 45. A bottom fixing post 482 is fixedly connected to the bottom of the bottom support piece 481.
[0044] Specifically, the water inlet pipe 331 in the water inlet assembly 33 is fixedly connected at its top to the bottom of the bottom connector 31. The water inlet pipe 331 serves as a transmission channel for external liquid to enter the bottom connector 31 and subsequent related components. When liquid input is required during equipment operation to meet cooling and cleaning needs, liquid can enter the designated component through the bottom connector 31 via the water inlet pipe 331, providing liquid support for related equipment operations. The bottom inlet 332, fixedly connected to the bottom of the water inlet pipe 331, can connect to an external water source transmission pipeline. Through the structural design of the bottom inlet 332, a stable connection between the external liquid and the water inlet pipe 331 is achieved, preventing liquid from being trapped during the process of entering the water inlet pipe 331. In case of leakage, the lower fixing frame 361 in the water inlet assembly 33 is fixedly connected to the top of the fixing ring 34. The lower fixing frame 361 can provide a connection and support between the fixing ring 34 and the upper handle 362, and transmit the force of the upper handle 362 to the fixing ring 34. At the same time, it provides a stable installation base for the upper handle 362. The upper handle 362 fixedly connected to the top of the lower fixing frame 361 can be used by the operator to apply force by holding the upper handle 362, so as to move the lower fixing frame 361 and the fixing ring 34 connected to it, which facilitates the installation and disassembly of the fixing ring 34 and related components, and improves the convenience of equipment operation.
[0045] The upper connector 371 in the water outlet assembly 37 has its bottom set on the top of the fixing ring 34. The upper connector 371 can serve as a connection and transition structure between the water outlet pipe 372 and the fixing ring 34 and related components, realizing the connection between the water outlet pipe 372 and the inside of the fixing ring 34. The water outlet pipe 372, which is fixedly connected to the top of the upper connector 371, serves as a channel component for the discharge of liquid inside the equipment. When wastewater generated during the operation of the equipment needs to be discharged, the liquid can enter the water outlet pipe 372 through the upper connector 371, and then be discharged from the water outlet pipe 372 to the designated external collection equipment, ensuring the timely discharge of liquid inside the equipment and avoiding liquid accumulation that could damage the equipment components.
[0046] The damping hole 461 in the shock absorber assembly 46 is located at the top of the bottom connecting shell 45. The damping hole 461 serves as the mounting and moving cavity for the damping slide rod 462, providing a defined movement space for the damping slide rod 462. At the same time, the damping hole 461 can be filled with a damping medium, and the damping effect is achieved through the interaction between the damping medium and the damping slide rod 462. The damping slide rod 462, which is slidably connected to the outer wall of the damping hole 461, can slide along the outer wall inside the damping hole 461 when the vacuum pump 2 generates vibration and transmits it to the bottom connecting shell 45. Through the friction and compression between the slide rod and the damping hole 461 and the internal damping medium, the vibration energy is consumed, further enhancing the damping effect of the shock absorber assembly 46, reducing the impact of vibration on the bottom connecting shell 45 and the components below, and maintaining the overall stability of the equipment operation.
[0047] The bottom connecting piece 471 in the water inlet assembly 47 is fixedly connected to the front side of the bottom connecting shell 45 on its rear side. The bottom connecting piece 471 can serve as a connecting carrier between the water inlet ring 472 and the bottom connecting shell 45, providing a stable installation position for the water inlet ring 472, and realizing the force transmission between the water inlet ring 472 and the bottom connecting shell 45, ensuring the structural stability of the water inlet ring 472 during liquid transmission. The water inlet ring 472 fixedly connected to the top of the bottom connecting piece 471 can be connected to an external liquid delivery pipeline. External liquid enters the interior of the bottom connecting shell 45 through the water inlet ring 472, providing an access port for the liquid supply required during equipment operation, ensuring that the liquid can enter the interior of the equipment stably and efficiently.
[0048] Working principle: This equipment consists of two core parts: buffer mechanism 3 and vacuum mechanism 4. Buffer mechanism 3 mainly provides installation support, buffer protection and fluid transfer assistance for the built-in water pump 1. Vacuum mechanism 4 mainly provides structural fixation, vibration buffering and vacuum extraction support for the vacuum pump 2. The two mechanisms work together through the coordinated operation of their respective components and potential functional connections to achieve stable operation of the equipment in specific working scenarios and meet the comprehensive operation requirements of fluid processing and vacuum extraction.
[0049] The bottom connector 31 in the buffer mechanism 3 is fixedly connected to the bottom of the built-in water pump 1 at its top and to the rear side of the inner wall of the buffer layer 32 at its rear. A water inlet assembly 33 is installed at the bottom. The bottom connector 31 serves two purposes: firstly, it provides a base for the built-in water pump 1, transmitting the weight of the pump and the force generated during operation to the buffer layer 32; secondly, it acts as a transitional structure between the water inlet assembly 33 and the built-in water pump 1, enabling communication between the internal fluid channels of the water inlet assembly 33 and the built-in water pump 1. The outer wall of the buffer layer 32 is fixedly connected to the fixing ring 34. When the built-in water pump 1 vibrates during operation, the vibration is transmitted to the buffer layer 32 through the bottom connector 31. The buffer layer 32 absorbs some of the vibration energy through its own structural deformation, reducing the transmission of vibration to the fixing ring 34 and subsequent components. Simultaneously, the fixing ring 34 provides external structural support for the buffer layer 32, preventing it from losing its buffering function due to excessive deformation. 4. The bottom is fixedly connected to the bottom shell 35, the top is provided with a handle assembly 36, and the rear side of the top is provided with a water outlet assembly 37. The fixing ring 34 can integrate the buffer layer 32, the bottom shell 35, the handle assembly 36 and the water outlet assembly 37 into a whole structure, realizing the force transmission and position positioning between the components. The handle assembly 36 facilitates the operator to move the fixing ring 34 and related components. The water outlet assembly 37 provides a channel for the discharge of fluid generated during the operation of the built-in water pump 1. The outer wall of the bottom shell 35 is fixedly connected to multiple external reinforcing ribs 38. The top of each external reinforcing rib 38 is fixedly connected to a reinforcing rib fastener 39. The external reinforcing ribs 38 can enhance the structural strength of the bottom shell 35 and prevent the bottom shell 35 from deforming when subjected to external pressure. The reinforcing rib fastener 39 further fixes the position of the external reinforcing ribs 38, ensuring the stability of the connection between the external reinforcing ribs 38 and the bottom shell 35, and jointly improving the structural load-bearing capacity of the bottom shell 35.
[0050] The side connector 41 in the vacuum mechanism 4 is fixedly connected to the left side of the vacuum pump 2 on its right side, and the four corners on the right side are threaded together by fixing bolts 42. The bottom is fixedly connected to the bottom outer shell 44. The side connector 41 provides left-side mounting support for the vacuum pump 2. The fixing bolts 42 enhance the tightness of the connection between the side connector 41 and the vacuum pump 2, preventing relative displacement between the vacuum pump 2 and the side connector 41 during operation. Simultaneously, the side connector 41 transfers the weight of the vacuum pump 2 to the bottom outer shell 44. The top of the vacuum pump 2 is fixedly connected to the vacuum tube 43. When the vacuum pump 2 is started, a negative pressure is formed inside. Gas from the external area to be pumped is drawn into the vacuum pump 2 through the vacuum tube 43, and then... Vacuum pump 2 discharges, thereby creating a vacuum state in the area to be extracted; the bottom of the side connector 41 is fixedly connected to the bottom outer shell 44, and the bottom of the bottom outer shell 44 is fixedly connected to the bottom connecting shell 45. The bottom outer shell 44 provides a top mounting carrier for the bottom connecting shell 45, further transmitting the force transmitted by the side connector 41 to the bottom connecting shell 45. At the same time, the bottom outer shell 44 protects the internal cables and pipe components; the bottom connecting shell 45 is equipped with a shock-absorbing component 46 on the top, a water inlet component 47 on the front, and a bottom support component 48 on the bottom. The bottom connecting shell 45 serves as the mounting base for the shock-absorbing component 46, the water inlet component 47, and the bottom support component 48, realizing the force transmission and functional connection between the three and the bottom outer shell 44;
[0051] In the overall operation of the equipment, the operator first applies force by holding the upper handle 362 of the handle assembly 36 in the buffer mechanism 3, which moves the lower fixed frame 361 and the fixed ring 34 connected to it, adjusting the buffer mechanism 3 and the built-in water pump 1 to the designated working position. At the same time, the bottom fixed column 482 of the bottom support assembly 48 in the vacuum mechanism 4 contacts the ground, stabilizing the vacuum mechanism 4 and the vacuum pump 2 in the working position. Subsequently, the bottom water inlet 332 of the water inlet assembly 33 of the buffer mechanism 3 is connected to an external water source, and the external liquid flows through the bottom inlet. Water enters the water inlet 332 into the water supply pipe 331, and then enters the built-in water pump 1 through the water supply pipe 331 and the bottom connector 31. After the built-in water pump 1 starts, it pressurizes the liquid. The treated liquid enters the water outlet pipe 372 through the upper connector 371 of the water outlet assembly 37, and is finally discharged to the designated equipment through the water outlet pipe 372. At the same time, the vacuum pump 2 starts to operate, and a negative pressure is formed inside it. The gas in the vacuum area to be vacuumed is drawn into the vacuum pump 2 through the vacuum pipe 43, and discharged after being processed by the vacuum pump 2, thus realizing the vacuum extraction operation of the area to be vacuumed.
[0052] During equipment operation, the vibration generated by the built-in water pump 1 is transmitted to the buffer layer 32 through the bottom connector 31. The buffer layer 32 absorbs the vibration energy through its own structural deformation, reducing the transmission of vibration to the fixed ring 34 and the bottom shell 35. The outer reinforcing ribs 38 on the outer wall of the bottom shell 35 enhance the structural strength of the bottom shell 35 and further disperse the vibration force, preventing the bottom shell 35 from being damaged by vibration. The vibration generated by the operation of the vacuum pump 2 is transmitted to the bottom outer shell 44 through the side connector 41, and then from the bottom outer shell 44 to the bottom connecting shell 45. In the damping component 46 at the top of the bottom connecting shell 45, the damping slide rod 462 slides along the outer wall in the damping hole 461, generating friction and compression with the damping medium inside the damping hole 461, consuming vibration energy and reducing the transmission of vibration to the bottom support component 48 and the ground. The bottom support plate 481 of the bottom support component 48 evenly transmits the force of the bottom connecting shell 45 to the bottom fixed column 482. The bottom fixed column 482 is in close contact with the ground, ensuring the stable placement of the vacuum mechanism 4.
