[0056] As shown in the water pump elastic connection assembly for reducing vibration and noise, the vibration and noise can be reduced, and the elastic connection assembly is convenient to disassemble and assemble. Figures 1-10 The specific use process is as follows:

[0057] When the elastic connection assembly 400 is installed, first, the closed ring 410 is accurately placed outside the outlet ring body 111, and the process needs to ensure that the plug-in mounting rod 320 is completely corresponding to the plug-in mounting hole. When the plug-in mounting rod 320 is successfully plugged into the plug-in mounting hole, the arc plate side insertion strip is inserted into the arc plate insertion strip slot, and the plug-in mounting rod 320 is limitedly plugged on the limiting arc plate 310. This combination action can preliminarily limit the elastic connection assembly 400, and lay a stable foundation for subsequent installation. Then, the wheel mounting frame 241 is pulled, and the side wing limiting frame 242 on both sides is limited to slide. At this time, the limiting wheel 245 stably rolls between the two groups of wheel limiting members 205 in the limiting groove block. Then, the second spring 229 is compressed by pressing the insertion sliding frame 224, and the first connecting plate 213 is moved by the clamping rod fixing frame 221. Then, the clamping hole on the first connecting plate 213 is aligned with the clamping rod 222. This process realizes accurate positioning of the elastic connection assembly 400. Finally, the locking nut is mounted on the fixed stud 412, and the nut is moderately tightened to tightly engage the components, thereby firmly installing the elastic connection assembly 400 and effectively preventing the elastic connection assembly 400 from being separated during the operation of the water pump, thereby significantly improving the stability of the elastic connection assembly 400.

[0058] When the elastic connection assembly 400 is disassembled, only the operation in the reverse order of the installation steps is needed. First, loosen the locking nut to release the fastening constraint of the elastic connection assembly 400. Then, the clamping rod 222 is removed in the reverse direction. Finally, the closed ring 410 is removed from the right side of the water pump body 1 to complete the entire disassembly process. By arranging the elastic connection assembly 400 which is convenient to install and disassemble, when the elastic connection assembly 400 is damaged due to long-term use, maintenance personnel can quickly disassemble and replace it, which not only greatly shortens the maintenance time, but also reduces the maintenance cost, and greatly facilitates the daily equipment maintenance work.

[0059] The working process of the water pump is based on mature fluid mechanics principles. The motor is connected with the impeller 137 through a high-precision connecting shaft 133. When the motor is powered on and started, the connecting shaft 133 drives the impeller 137 to rotate at a stable speed. The impeller 137 generates a strong centrifugal force during rotation, which causes the liquid to be quickly sucked from the water inlet. Under the action of the impeller 137, the liquid gains kinetic energy and the pressure is increased. Finally, the liquid is discharged from the water outlet. To ensure that the water pump does not leak during operation, a sealing system composed of a packing ring 134, an annular gland 135, a second spring 131 and a gasket 132 is specially designed. The packing ring 44 fills the gap between the shaft and the pump body, and cooperates with the elastic pressure of the second spring 131 to compress the packing ring 134, forming a reliable sealing structure. The gasket 132 plays a role in auxiliary sealing and protecting components. In addition, the base 136 is made of high-strength material, and through scientific structural design and precise installation process, the stability of the overall structure of the water pump is ensured, so that it can operate stably in complex working environment. In the field of water supply and drainage, the water pump can efficiently transport and distribute water resources. In industrial processes, whether it is the transportation of liquid raw materials or the cooling cycle in the production process, the water pump plays an indispensable role. With its stable and reliable performance, it meets the needs of continuous liquid transportation in different scenarios.

[0060] The above structure is provided with an elastic connection assembly convenient for installation and disassembly. When the elastic connection assembly body is damaged due to long-term use, maintenance personnel can quickly disassemble and replace it, which not only greatly shortens the maintenance time, but also reduces the maintenance cost, greatly facilitating daily equipment maintenance work.

[0061] The elastic connection assembly body can effectively absorb and buffer vibrations of different frequencies and amplitudes generated during the operation of the water pump. The inner elastic layer absorbs high-frequency and small vibrations, the outer elastic layer provides protection and structural strength, and the vibration-absorbing spring absorbs low-frequency and large-amplitude vibrations, forming a multi-level and all-around vibration-absorbing system, which significantly improves the vibration-absorbing effect.

[0062] By threadedly connecting the locking nut along the fixing stud, and by moderately tightening the nut, the components are tightly engaged, achieving firm installation of the connection assembly body, effectively preventing the connection assembly body from detaching during the operation of the water pump, and significantly improving the stability of the connection assembly body.

[0063] Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed application.
