Technical Field

[0001] The present invention relates to the technical field of circulating pumps, and in particular to a high-efficiency and energy-saving circulating pump for a heat exchange station. Background Art

[0002] In centralized heating, industrial production, and regional energy systems, heat exchange stations serve as the core nodes for heat exchange and distribution, and their performance directly affects system energy efficiency, operating costs, and user experience.

[0003] As a key equipment in the heat exchange station, the circulation pump is responsible for driving the circulation of heat medium and achieving efficient heat transfer. It plays the role of "heart" in the entire heat exchange process.

[0004] Since the core function of the circulation pump is to convert electrical energy into kinetic energy and pressure energy of the fluid by driving the impeller to rotate through the motor, the circulation pump will vibrate when in use, which will not only increase the wear of the motor and pump shaft bearings and shorten the service life of the circulation pump, but also generate loud noise when the circulation pump vibrates violently, causing noise pollution to the surrounding environment. Therefore, we propose a high-efficiency and energy-saving circulation pump for heat exchange stations to solve the above problems. Summary of the Invention

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] Example 1, as Figure 1-7 As shown, a high-efficiency and energy-saving circulating pump for a heat exchange station includes a circulating pump body 1, a base 2 is fixedly connected to the bottom of the circulating pump body 1, a connecting seat 3 fixed to the ground by bolts is provided below the base 2, a shock-absorbing component 4 is provided inside the connecting seat 3, and a mounting component 5 is provided below the base 2.

[0031] The model of the above-mentioned circulation pump body 1 is GW type, which is a single-stage single-suction cantilever centrifugal pump for conveying liquids that do not contain solid particles, are corrosive, and have a viscosity similar to water. The pump body material can be selected from stainless steel 304, stainless steel 316L and duplex steel. It has the characteristics of a wide performance range, high efficiency, and easy maintenance.

[0032] Specifically, in order to achieve the purpose of buffering the vibration generated by the circulating pump during operation, refer to Figure 2 and Figure 3 In this embodiment, the shock absorbing assembly 4 includes a connecting plate 41, the top of the connecting plate 41 contacts the bottom of the base 2, and the outer surface of the bottom of the connecting plate 41 is rotatably connected to two rotating rods 411.

[0033] For further information, see Figure 4 In this embodiment, the inner walls of the bottoms of the two rotating rods 411 are rotatably connected to the sliding plates 42, and two circular holes are provided at the ends of the two connecting plates 41 away from each other.

[0034] During the implementation process, when the circulation pump body 1 vibrates in the working state, the vibration force will push the connecting plate 41 downward through the base 2. When the connecting plate 41 moves downward, it will drive the two rotating rods 411 to rotate. When the rotating rods 411 rotate, they will push the corresponding sliding plates 42 to slide on the outer surfaces of the two fixed rods 44.

[0035] For further information, see Figure 4 In this embodiment, two fixing rods 44 are provided under the connecting plate 41. The front and back surfaces of the two fixing rods 44 are fixedly connected to the inner surface of the connecting seat 3, and the inner walls of the four circular holes are slidably connected to the outer surface of the fixing rod 44 on the same side.

[0036] For further information, see Figure 4 In this embodiment, two shock absorbers 43 are installed on the inner surface of the connecting seat 3, and the inner walls of the two shock absorbers 43 are slidably connected with connecting rods, and the ends of the two connecting rods close to each other are fixedly connected to the ends of the sliding plate 42 on the same side away from the center of the connecting plate 41.

[0037] For further information, see Figure 4 In this embodiment, the outer surfaces of the two shock absorbers 43 are both sleeved with springs 431, and the ends of the two springs 431 that are close to each other are fixedly connected to the ends of the sliding plate 42 on the same side away from the connecting plate 41, and the ends of the two springs 431 that are away from each other are fixedly connected to the inner surface of the connecting seat 3.

[0038] For further information, see Figure 3 and Figure 4In this embodiment, the four corners of the top of the connecting seat 3 are fixedly connected with a connecting block 45, the inner surfaces of the four connecting blocks 45 are fixedly connected with a round rod 451, and the outer surfaces of the four round rods 451 are slidably connected to the inner wall of the connecting plate 41.

[0039] During implementation, when the sliding plate 42 moves, it will squeeze the spring 1 431 to cause it to deform. The deformed spring 1 431 will generate an elastic force opposite to the movement of the sliding plate 42, so that the vibration force generated by the circulation pump body 1 when working can be buffered and offset. At the same time, the sliding plate 42 will squeeze the shock absorber 43 to prevent the spring 1 431 from quickly pushing the sliding plate 42 back to its original position due to the elastic force, which can effectively alleviate the vibration generated by the circulation pump body 1 when working, not only reducing the wear on the motor and pump shaft bearings inside the circulation pump body 1, and improving the service life of the circulation pump body 1, but also greatly reducing the noise generated, avoiding noise pollution to the surrounding environment.

[0040] Embodiment 2: This embodiment provides an installation component based on embodiment 1.

[0041] Specifically, in order to quickly install and disassemble the circulating pump, refer to Figure 5 and Figure 6 In this embodiment, the mounting assembly 5 includes four square tubes 51, and four square recessed holes are opened on the top of the connecting plate 41. The outer surfaces of the four square tubes 51 are fixedly connected to the inner walls of the square recessed holes on the same side. The inner walls of the four square tubes 51 are slidably connected with connecting blocks 2 52, and the tops of the four connecting blocks 2 52 are fixedly connected to the bottom of the base 2.

[0042] For further information, see Figure 6 and Figure 7 In this embodiment, two fixed blocks 54 are fixedly connected to the bottom of the connecting plate 41, and the front and back sides of the two fixed blocks 54 are fixedly connected to round rods 541. The outer surfaces of the four round rods 541 are slidably connected to the insertion rods 53. The outer surfaces of the four insertion rods 53 are slidably connected to the inner wall of the square tube 51 on the same side, and the left ends of the two insertion rods 53 on the left and the right ends of the two insertion rods 53 on the right are fixedly connected to the pull handles 531.

[0043] For further information, see Figure 6 In this embodiment, the four connecting blocks 52 are each provided with a socket at one end close to the fixing block 54 on the same side, and the inner walls of the four sockets are connected to the outer surface of the side of the insertion rod 53 on the same side away from the fixing block 54.

[0044] For further information, see Figure 6In the embodiment, the outer surfaces of the four second circular rods 542 are sleeved with springs 542, one ends of the four springs 542 away from the same side fixed block 54 are fixedly connected with the one ends of the same side insertion rods 53 close to the fixed block 54, and the other ends of the four springs 542 away from the same side insertion rods 53 are fixedly connected with the one ends of the same side fixed blocks 54 close to the insertion rods 53.

[0045] In the implementation process, when the circulating pump body 1 needs to be replaced and maintained due to damage, first, four pull handles 531 are pulled to drive the insertion rods 53 to slide in the inner walls of the corresponding square cylinders 51, the insertion rods 53 move to drive the outer surfaces of the corresponding second circular rods 541 to slide, the insertion rods 53 slide to extrude the springs 542 to deform, when the insertion rods 53 move a certain distance, the outer surfaces of the insertion rods 53 can be separated from the inner walls of the corresponding insertion holes to release the restriction on the second connecting blocks 52, so that the base 2 and the circulating pump body 1 can be quickly and conveniently removed, which not only maximally reduces the risk of system interruption caused by equipment failure to protect normal use of users, but also reduces the dependence on complex tools and professional skills, and ordinary maintenance personnel can efficiently complete the operation.

[0046] The working principle of the application is that when the circulating pump body 1 vibrates in the working state, the vibration force pushes the connecting plate 41 to move downward through the base 2, the connecting plate 41 moves downward to drive the two rotating rods 411 to rotate, the rotating rods 411 rotate to push the corresponding sliding plates 42 to slide on the outer surfaces of the two fixed rods 44, the sliding plates 42 move to extrude the springs 431 to deform, the deformed springs 431 generate an elastic force opposite to the movement of the sliding plates 42, so that the vibration force generated when the circulating pump body 1 works can be buffered and offset, at the same time, the sliding plates 42 extrude the shock absorbers 43 to avoid the springs 431 quickly pushing the sliding plates 42 back to the original position due to the elastic force, which can effectively alleviate the vibration generated when the circulating pump body 1 works, not only can reduce the wear of the motor and the pump shaft bearing in the circulating pump body 1 to improve the service life of the circulating pump body 1, but also can greatly reduce the generated noise to avoid noise pollution to the surrounding environment.

[0047] In the process of moving downward, the connecting plate 41 slides downward on the outer surfaces of the four first circular rods 451, and as the connecting plate 41 continuously moves downward, the outer surfaces of the first circular rods 451 can be extruded by the shock-absorbing springs sleeved thereon to deform, and the deformed shock-absorbing springs can increase the shock-absorbing effect of the device.

[0048] When the circulation pump body 1 is damaged and needs to be replaced and repaired, first pull the four handles 531 to drive the insertion rod 53 to slide in the inner wall of the corresponding square tube 51. When the insertion rod 53 moves, it will drive the corresponding round rod 2 541 to slide on the outer surface. While the insertion rod 53 slides, it will squeeze the spring 2 542 to cause it to deform. When the insertion rod 53 moves a certain distance, its outer surface can be separated from the inner wall of the corresponding socket, which can release the restriction on the connecting block 2 52, so that the base 2 and the circulation pump body 1 can be quickly and conveniently removed. This can not only minimize the risk of system interruption caused by equipment failure and ensure normal energy use for users, but also reduce dependence on complex tools and professional skills, and ordinary maintenance personnel can complete the operation efficiently.

[0049] When the circulation pump body 1 is repaired, the position angle of the base 2 is adjusted so that the four connecting blocks 2 52 at its bottom can match the positions of the corresponding square tubes 51, and the base 2 is placed on the top of the connecting plate 41. During the placement process, the base 2 will drive the connecting block 2 52 to be inserted into the corresponding square tube 51. As the connecting block 2 52 continues to move downward, it will contact the top of the insertion rod 53. Since the contact surfaces of the connecting block 2 52 and the insertion rod 53 are both inclined, the insertion rod 53 will be pushed to move as the connecting block 2 52 moves downward. When the base 2 is installed, the deformed spring 2 542 will push the insertion rod 53 to be inserted into the corresponding inner wall of the socket, so that the base 2 can be fixed on the top of the connecting plate 41.
