[0050] Reference Figure 7The disassembly and assembly plug-in limit mechanism 300 includes a limiting arc plate 310 and a plug-in installation rod 320. Arc plate side insertion strips are provided on both sides of the limiting arc plate 310, and an arc plate insertion groove is provided at one end of the plug-in installation rod 320. The arc plate side insertion strip is inserted into the arc plate insertion groove to realize the limited plug-in of the two. A connecting protrusion 311 is provided on one arc edge of the limiting arc plate 310, and the connecting protrusion 311 is fixedly installed on the row end ring body 111. The other end of the plug-in installation rod 320 is fixedly installed on the closed ring member 410. The row end ring body 111 is provided with a plug-in installation hole corresponding to the plug-in installation rod 320. When the elastic connection component 400 is installed, the plug-in installation rod 320 first passes through the plug-in installation hole and realizes limited plug-in with the limiting arc plate 310 to realize preliminary limited installation.

[0051] A closed ring arc strip 411 is fixedly installed on the ring edge of the closed ring part 410, and a fixed stud 412 is inserted into the closed ring arc strip 411. One end of the fixed stud 412 is fixedly installed on the row end ring body 111. The fixed stud 412 is used to install a locking nut.

A ring disc mounting hole is provided on the mounting end ring 430 for installing external parts.

[0053] A driving chamber 130 is provided in the water pump body 100, and a base 136 is fixedly installed in the driving chamber 130. A connecting shaft 133 is rotatably installed on the base 136. One end of the connecting shaft 133 extends to the outside of the water pump body 100, and is used to connect the driving power component to drive it to rotate. A packing ring 134 is provided on the side of the driving chamber 130 away from the base 136. The packing ring 134 fills the gap between the connecting shaft 133 and the cavity wall of the driving chamber 130. A gasket groove is provided on one side of the base 136, and a gasket 132 is installed in the gasket groove. The gasket 132 is sleeved on the connecting shaft 133. A spring pressing assembly is provided between the gasket 132 and the packing ring 134, which is used to press the gasket 132 and the packing ring 134 to tighten them to form a reliable sealing structure. An impeller 137 is installed on the shaft body of the connecting shaft 133. The rotation of the impeller 137 realizes the entry and discharge of fluid.

[0054] The spring pressing assembly is composed of two annular pressure covers 135 and a second spring 131 arranged between the two annular pressure covers 135. The second spring 131 presses the two annular pressure covers 135, thereby pressing the pressure washer 132 and the packing ring 134 tightly.

[0055] The water pump body 100 further includes an inlet pipe 120 , on which an inlet pipe mounting member 121 is mounted. The inlet pipe 120 and the discharge pipe 110 are both in communication with the driving chamber 130 .

[0056] like Figures 1-10 The vibration and noise reducing water pump elastic connection assembly shown can reduce vibration and noise and is easy to disassemble and assemble. The specific usage process is as follows:

[0057] When performing the installation operation of the elastic connection component 400, first place the closed ring part 410 accurately on the outside of the row end ring body 111. This process requires ensuring that the plug-in installation rod 320 is completely corresponding to the plug-in installation hole. After the plug-in installation rod 320 is successfully plugged into the plug-in installation hole, the side insert of the arc plate is inserted into the arc plate insert groove, and the plug-in installation rod 320 and the limiting arc plate 310 are limitedly plugged in. This combined action can perform preliminary limiting on the elastic connection component 400, laying a stable foundation for subsequent installation. Then, by pulling the wheel mounting frame 241, the side limit frames 242 on both sides thereof limit sliding. At this time, the limiting wheel 245 is The two sets of wheel limiters 205 in the limit slot block roll smoothly between each other, and then press the insertion slide 224 to compress the second spring 229, which is displaced by the clamping rod fixing frame 221. Then, the clamping hole on the first connecting plate 213 is aligned with the insertion clamping rod 222. This process realizes the precise positioning of the elastic connection component 400. Finally, the locking nut is installed along the fixing stud 412. By properly tightening the nut, the various components are tightly engaged, achieving a firm installation of the elastic connection component 400, effectively avoiding the separation of the elastic connection component 400 during the operation of the water pump, and significantly improving the stability of the elastic connection component 400.

[0058] When disassembling the elastic connection component 400, it is only necessary to operate in the reverse order of the installation steps. First, loosen the locking nut to release the fastening constraint on the elastic connection component 400. Then, insert the connecting rod 222 in reverse operation to remove it. Finally, remove the closing ring 410 from the right side of the water pump body 1 to complete the entire disassembly process. By setting up this elastic connection component 400 that is easy to install and disassemble, when the elastic connection component 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 daily equipment maintenance work.

[0059] The working process of the water pump is based on mature fluid mechanics principles. The motor is closely connected to the impeller 137 through a high-precision connecting shaft 133. When the motor is powered on, the connecting shaft 133 drives the impeller 137 to rotate at a high speed at a stable speed. The impeller 137 generates a strong centrifugal force during the rotation process. This centrifugal force causes the liquid to be quickly sucked in from the water inlet. Under the action of the impeller 137, the liquid obtains kinetic energy, the pressure is increased, and finally discharged from the water outlet. In order to ensure that there will be no liquid leakage during the operation of the water pump, a sealing system consisting 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. The gap, combined with the elastic pressure of the second spring 131, compresses the packing ring 134 to form a reliable sealing structure, and the gasket 132 plays the role of auxiliary sealing and protection components. In addition, the base 136 is made of high-strength materials. Through scientific structural design and precise installation technology, the stability of the overall structure of the water pump is ensured, so that it can operate stably in complex working environments. In the field of water supply and drainage, the water pump can efficiently realize the transportation and distribution of 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 component that is easy to install and disassemble. When the elastic connection component 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] It can effectively absorb and buffer vibrations of different frequencies and amplitudes generated during water pump operation. The inner elastic layer absorbs high-frequency micro-vibrations, while the outer elastic layer provides protection and structural strength. Combined with the absorption of low-frequency and large-amplitude vibrations by the vibration-damping spring, a multi-level, all-round vibration-damping system is formed, which significantly improves the vibration reduction effect.

[0062] By threading the locking nut along the fixing stud and properly tightening the nut, the components are tightly engaged, thereby achieving a secure installation of the connection assembly body, effectively avoiding 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 invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
