[0002] At present, centrifugal water pumps are widely used in industrial, civil and other fields, but there are two major problems during their operation: first, the vibration generated by the high-speed operation of the motor and water pump will cause noise pollution. At the same time, long-term vibration can easily cause the pump body parts to loosen, affecting the stability and service life of the equipment; second, when the water pump is turned off, the sudden cessation of water flow will produce a water hammer effect. The huge impact force will cause strong vibration to the pipeline, and in severe cases may cause pipeline rupture or equipment damage.

DETAILED DESCRIPTION
[0014] The following is a further detailed description of this application in combination with 1-6.
[0015] Example 1: A centrifugal ultra-quiet water pump, referring to Figure 1-6 , including a centrifugal pump 1, the centrifugal pump 1 includes a centrifugal unit 10, a noise reduction unit 20 is fixedly connected to the surface of the centrifugal unit 10, and a shock absorbing unit 30 is provided on the surface of the noise reduction unit 20; The shock absorbing unit 30 is used to deal with the water hammer effect when the centrifugal pump 1 is shut down, reduce the impact of the water hammer effect and reduce the vibration of the pipeline. The shock absorbing unit 30 includes a buffer tube 3001, the inner wall of the buffer tube 3001 is fixedly connected to the slide rail 2 3005, the inner wall of the slide rail 2 3005 is slidably connected to the buffer plug 3002, the inner wall of the slide rail 2 3005 is fixedly connected to the sealing ring 3003, the inner wall of the buffer tube 3001 is fixedly connected to the spring 3004, the surface of the buffer tube 3001 is fixedly connected to the support frame 3011, the bottom end of the support frame 3011 is fixedly connected to the buffer rod 3010, and the bottom end of the buffer rod 3010 is fixed. It is connected to spring four 3009, and the end of spring four 3009 away from the buffer rod 3010 is fixedly connected to the buffer seat 3008, the top of the support frame three 3011 is fixedly connected to the rotating seat two 3012, the inner wall of the rotating seat two 3012 is rotatably connected to the rotating rod two 3013, the inner wall of the rotating rod two 3013 away from the rotating seat two 3012 is slidably connected to the slide rail three 3007, the outer side of the slide rail three 3007 is fixedly connected to the support frame two 3006, the end of the rotating rod two 3013 away from the support frame two 3006 is fixedly connected to the spring five 3014, and a water outlet 3015 is provided on the surface of the buffer tube 3001.
[0016] The shock absorbing unit 30 effectively copes with the water hammer effect generated when the centrifugal pump 1 is shut down and reduces pipeline vibration through the coordinated action of multiple buffer structures: when the water flow is impacted by the shutdown of the pump body, the buffer plug 3002 in the buffer tube 3001 slides on the second slide rail 3005 and compresses the third spring 3004, converting the kinetic energy of the water into elastic potential energy, thereby initially weakening the impact force; at the same time, the sealing ring 3003 ensures that the water flow is discharged only through the water outlet 3015, avoiding pressure leakage affecting the buffering effect. When the buffer tube 3001 vibrates, the support frame 3 on its surface 3011 squeezes spring four 3009 through the buffer rod 3010, and spring four 3009 deforms in the buffer seat 3008 to absorb vibration energy. At the same time, the rotating seat two 3012 drives the rotating rod two 3013 to rotate, and the rotating rod two 3013 slides along the slide rail three 3007 and compresses the spring five 3014, forming a multi-angle buffer. Through the triple buffering of spring three 3004, spring four 3009, and spring five 3014, the water hammer effect is gradually weakened, ultimately reducing the pipeline vibration amplitude and protecting the safety of the pump body and pipeline system.
[0017] The inner wall of spring five 3014 is slidably connected to the surface of slide rail three 3007, the end of spring three 3004 away from the inner wall of buffer tube 3001 is fixedly connected to buffer plug 3002, and the bottom end surface of buffer rod 3010 is slidably connected to the inner wall of buffer seat 3008.
[0018] The inner wall of the spring five 3014 is slidably connected to the surface of the slide rail three 3007, ensuring that the rotating rod two 3013 can slide smoothly along the slide rail three 3007 and accurately compress the spring five 3014 during the rotation process, so that the spring five 3014 is only deformed by the axial force, avoiding lateral deviation and buffer failure; the end of the spring three 3004 away from the inner wall of the buffer tube 3001 is fixedly connected to the buffer plug 3002, ensuring that when the water flow impacts the buffer plug 3002, the spring three 3004 can respond immediately and generate elasticity The buffer rod 3010 is connected with the inner wall of the buffer seat 3008 in a sliding manner, so that the buffer rod 3010 can slide vertically along the inner wall of the buffer seat 3008 and compress the spring four 3009 when the buffer tube 3001 vibrates, thereby ensuring that the vibration energy is effectively transmitted to the spring four 3009 and limiting the movement trajectory of the buffer rod 3010 to avoid structural damage due to shaking.
[0019] The centrifugal unit 10 includes a motor 1001, the output end of the motor 1001 is fixedly connected to a water pump 1002, the surface of the water pump 1002 is provided with a water inlet 1003, the surface of the water pump 1002 is fixedly connected to a water outlet pipe 1004, and the surface of the water pump 1002 is fixedly connected to a support block 1005.
[0020] The centrifugal unit 10 serves as the core power and water delivery structure of the water pump, and realizes the fluid delivery function through the coordinated cooperation of the motor 1001, the water pump 1002, the water inlet 1003, the water outlet pipe 1004 and the support block 1005: the output end of the motor 1001 is fixedly connected to the water pump 1002, providing rotational power for the water pump 1002, so that the water pump 1002 sucks the fluid through the water inlet 1003 and discharges it through the water outlet pipe 1004 under pressure; the support block 1005 on the surface of the water pump 1002 and the support block 1005 in the noise reduction unit 20 are connected. The inner wall of the frame 1 2007 is fixedly connected, which not only provides structural support for the water pump 1002 and the motor 1001, but also transmits the vibration generated during the operation of the motor 1001 and the water pump 1002 to the noise reduction unit 20. Through the coordinated action of the support frame 1 2007 and the buffer structures such as the spring 2 2009 and the spring 1 2004 in the noise reduction unit 20, the vibration energy is absorbed and the noise is reduced. At the same time, the stability of the centrifugal unit 10 during high-speed operation is ensured, and loosening of components or failure of connections due to vibration is avoided.
[0021] The surface of the motor 1001 is fixedly connected to the inner wall of the support frame 2007 , the surface of the support block 1005 is fixedly connected to the inner wall of the support frame 2007 , and the surface of the water outlet pipe 1004 is fixedly connected to the surface of the buffer pipe 3001 .
[0022] The surface of the motor 1001 is fixedly connected to the inner wall of the support frame 1 2007, and the surface of the support block 1005 is fixedly connected to the inner wall of the support frame 1 2007. This structure firmly installs the centrifugal unit 10 on the noise reduction unit 20, so that the vibration generated by the operation of the motor 1001 and the water pump 1002 is directly transmitted to the support frame 1 2007 through the support block 1005 and the motor 1001, and then the spring 2 2009 and the spring 1 2004 connected to the support frame 1 2007 are used for double buffering, which effectively reduces the vibration noise; the surface of the water outlet pipe 1004 is fixedly connected to the buffer The surface of the flushing pipe 3001 is fixedly connected, so that the water discharged from the water pump 1002 directly enters the buffer pipe 3001. When the water pump 1002 is turned off and a water hammer effect occurs, the impact of the water flow can immediately act on the buffer plug 3002 in the buffer pipe 3001, triggering the triple buffering mechanism of spring three 3004, spring four 3009 and spring five 3014, thereby achieving a rapid response and effective weakening of the water hammer effect. At the same time, this fixed connection method ensures the coordinated work of the centrifugal unit 10 and the shock absorbing unit 30, so that the entire water pump system can remain stable both in operation and in shutdown states.
[0023] The bottom end of the buffer seat 3008 is fixedly connected to the surface of the mounting seat 2001 , and the surface of the second support frame 3006 is fixedly connected to the surface of the mounting seat 2001 .
[0024] The bottom end of the buffer seat 3008 is fixedly connected to the surface of the mounting seat 2001, providing a stable support base for the spring four 3009, so that the buffer rod 3010 can slide vertically along the inner wall of the buffer seat 3008 and squeeze the spring four 3009 when the buffer tube 3001 vibrates, ensuring that the vibration energy is effectively absorbed by the elastic deformation of the spring four 3009; the surface of the support frame 2 3006 is fixedly connected to the surface of the mounting seat 2001, providing a stable installation foundation for the slide rail three 3007, so that the rotating rod 2 3013 can stably slide along the slide rail three 3007 driven by the rotating seat 2 3012. Compression spring five 3014 is used to achieve multi-angle buffering of the vibration of the buffer tube 3001. The two are fixedly connected to the mounting seat 2001, so that the shock absorbing unit 30 is reliably mounted on the base structure of the noise reduction unit 20. This not only ensures the stability of the force direction of spring four 3009 and spring five 3014 during the buffering process, but also enables the shock absorbing unit 30 and the noise reduction unit 20 to form a coordinated whole. When dealing with the water hammer effect, the supporting role of the buffer seat 3008 and the support frame two 3006 allows the triple buffer structure to orderly undertake and gradually weaken the impact energy, thereby ultimately achieving effective reduction of pipeline vibration.
[0025] Example 2: A centrifugal ultra-quiet water pump, the noise reduction unit 20 is used to reduce the noise generated by the vibration of the centrifugal water pump during operation, and long-term vibration may cause the parts of the pump body to loosen, the noise reduction unit 20 includes a mounting seat 2001, the surface of the mounting seat 2001 is fixedly connected to a slide rail 2002, the surface of the slide rail 2002 is slidably connected to a slider 2003, the inner wall of the slider 2003 is rotatably connected to a rotating rod 2005, and the surface of the rotating rod 2005 away from the slider 2003 is rotatably connected to Rotating seat 2006, the surface of rotating seat 2006 is fixedly connected to support frame 2007, the surface of support frame 2007 is fixedly connected to limit rod 2008, the surface of limit rod 2008 is slidably connected to spring 2009, the top of spring 2009 is fixedly connected to support frame 2007, the bottom end of spring 2009 is fixedly connected to the surface of mounting seat 2001, the surface of slide rail 2002 is slidably connected to spring 2004, and the surface of slide rail 2002 is fixedly connected to limit block 2010.
[0026] The noise reduction unit 20 effectively reduces the vibration noise of the centrifugal water pump during operation and prevents the loosening of parts through a multi-stage buffer structure: the vibration of the motor 1001 and the water pump 1002 is transmitted to the surface fixedly connected to the inner wall of the support frame 1 2007 through the support block 1005, so that the support frame 1 2007 moves up and down along the limit rod 1 2008 and compresses the spring 2 2009. The elastic deformation of the spring 2 2009 absorbs part of the vibration energy; at the same time, the shaking of the support frame 1 2007 drives the rotating seat 1 2006 to rotate, and the rotating seat 1 2006 By rotating rod 1 2005, slider 1 2003 is driven to slide on slide rail 1 2002, and slider 1 2003 squeezes spring 1 2004. The elastic deformation of spring 1 2004 further absorbs vibration energy; limit block 2010 limits the sliding range of slider 1 2003 to avoid damage caused by excessive displacement of the structure. Through the dual buffering of spring 2 2009 and spring 1 2004, the structure realizes the gradual weakening of vibration energy, effectively reduces noise generation, and reduces the risk of loosening of components due to rigid vibration through elastic buffering.
[0027] There are two sliders 2003, which are linearly arranged along the surface of the slide rail 2002. The inner walls of the two sliders 2003 are rotatably connected to the same rotating rod 2005, and both ends of the spring 2009 are fixedly connected to the slider 2003.
[0028] Two sliders 2003 are provided and linearly arranged along the slide rail 2002. The two are rotatably connected to the rotating seat 2006 through the same rotating rod 2005. The two ends of the spring 2009 are respectively fixed to the two sliders 2003. This structure forms a two-way linkage buffer mechanism: when the support frame 2007 moves up and down due to vibration, the rotating seat 2006 rises and falls synchronously and drives the rotating rod 2005 to rotate, forcing the two sliders 2003 to slide toward or away from each other along the slide rail 2002, synchronously squeezing or stretching the spring 2004; the spring 2009 produces elastic deformation during the sliding process of the slider 2003, further absorbing the vibration energy. Through the symmetrical distribution of the two sliders 2003 and the coordinated action of the spring 2009, the structure realizes efficient decomposition and absorption of the vibration energy, while ensuring the balance of the buffering force in the horizontal direction, avoiding structural deviation caused by unilateral force, and significantly improving the stability and buffering efficiency of the noise reduction unit 20.
[0029] There are two support frames 2007 , and the two support frames 2007 are linearly arranged along the surface of the mounting base 2001 .
[0030] Two support frames 2007 are provided and are linearly arranged along the surface of the mounting seat 2001. The symmetrical arrangement provides balanced supporting force for the motor 1001 and the water pump 1002 in the centrifugal unit 10, ensuring that the vibration energy of the motor 1001 and the water pump 1002 during operation is evenly transmitted to the two support frames 2007, avoiding structural tilt or stress concentration caused by unilateral force; each support frame 2007 is connected to the corresponding slider 2003 through the rotating seat 2006 and the rotating rod 2005, and cooperates with the spring 2 2009 and the spring 1 2004 to form a double buffer structure. The synchronous linkage of the two support frames 2007 can synergistically absorb vibration energy, thereby improving the buffering efficiency of the noise reduction unit 20 on the vibration of the centrifugal unit 10, and at the same time enhancing the stability of the overall structure, and preventing loose connections or component damage due to long-term vibration.
