Description

Technical Field

[0001] This invention belongs to the field of pump technology, specifically relating to an energy-saving magnetic pump with an integrated exhaust pressure stabilizing chamber and an anti-dry-running structure in the rear cover. Background Technology

[0002] In the field of magnetic pump technology, especially in applications involving easily vaporized media, maintaining stable internal pressure and preventing dry-running for heat dissipation are key technical challenges determining pump performance and reliability. Existing solutions often suffer from structural deficiencies and systemic defects in addressing these issues.

[0003] Cavitation and pressure fluctuation issues have not been addressed synergistically: Traditional magnetic pumps often use external venting valves or independent venting devices to discharge gas. However, the pump's internal volume changes during venting, which can easily lead to sudden changes in internal pressure, affecting flow stability and system efficiency. Furthermore, the failure to replenish liquid medium promptly after venting further exacerbates pressure fluctuations and the risk of cavitation, especially during frequent start-stop operations or when operating under varying conditions.

[0004] The separation of the exhaust and cooling systems leads to complex structures and insufficient heat dissipation: Existing magnetic pumps typically have independent exhaust and cooling systems, resulting in large space requirements, low integration, and difficulty in effectively dissipating heat from the pump body, especially critical components such as the magnetic coupling area and isolation sleeve, under idling or without media cooling conditions. Traditional fans or external cooling devices often fail to achieve precise, directional, and staged cooling, leading to excessive temperature rise during dry-running or low-load operation, affecting service life and operational safety.

[0005] Lack of integrated pressure stabilization and exhaust coordination mechanism: Although some magnetic pumps have attempted to introduce a pressure stabilization chamber structure, it is mostly integrated with the front cover or the side of the pump body, failing to form an effective linkage with the rear cover and exhaust path. This separate design results in gas exhaust and liquid replenishment not being synchronized, leading to a slow pressure stabilization response and difficulty in maintaining pressure balance during dynamic operation. It also limits the overall compactness and energy efficiency of the structure.

[0006] Therefore, there is an urgent need for a new magnetic pump structure that can highly integrate exhaust, pressure stabilization and anti-dry-running heat dissipation functions, especially a structure that uses the rear cover as a carrier to achieve multi-system synergy. Summary of the Invention

[0007] To address the problems mentioned in the background art, the present invention provides an energy-saving magnetic pump with an integrated exhaust pressure stabilizing chamber and anti-dry-running structure in the rear cover, which features a high degree of integration of exhaust, pressure stabilization and anti-dry-running heat dissipation functions.

Through the rotation of the primary rear cover exhaust assembly at the rear end of the magnetic pump assembly, primary exhaust heat dissipation is achieved when the magnetic pump assembly is prevented from running dry. Through the rotation of the secondary exhaust assembly, secondary exhaust heat dissipation is achieved when the magnetic pump assembly is prevented from running dry.

[0015] In a preferred embodiment of an energy-saving magnetic pump with an integrated exhaust pressure stabilizing chamber and anti-dry-spinning structure in the rear cover, two sets of pressure stabilizing arm assemblies are rotatably mounted on a first pressure stabilizing chamber and a second pressure stabilizing chamber, respectively. In one set of pressure stabilizing arm assemblies, the shaft at one end of the pressure stabilizing arm shaft is rotatably mounted on the first pressure stabilizing chamber via a bearing.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The magnetic pump assembly of the present invention has a pressure stabilizing chamber assembly in the middle. The pressure stabilizing chamber assembly has pressure stabilizing arm assemblies rotatably mounted on the top and bottom. The pressure stabilizing arm assembly inside the first pressure stabilizing chamber extracts the gas inside the pump housing, and the pressure stabilizing arm assembly inside the second pressure stabilizing chamber fills the pump housing with liquid. Since the two sets of pressure stabilizing arm assemblies rotate synchronously, the venting and filling of the pump housing are carried out simultaneously through the two sets of pressure stabilizing arm assemblies. With this structure, the venting of the magnetic pump assembly is achieved at the same time as the filling of the venting space with liquid, avoiding the rapid fluctuation of the pump internal pressure caused by the change of the venting space during venting.

The primary rear cover exhaust assembly is connected to the output shaft inside the magnetic pump assembly.

Through this structure, the primary rear cover exhaust assembly is driven in tandem with the magnetic pump assembly when it starts. At the same time, through the above-mentioned planetary gear meshing structure, the synchronous driving of multiple voltage stabilizing arm assemblies, the primary rear cover exhaust assembly, and the secondary exhaust assembly are simultaneously achieved.

[0022] 3. This invention achieves synchronous rotation of the primary rear cover exhaust assembly and the secondary exhaust assembly while multiple sets of pressure stabilizing arm assemblies rotate synchronously. The rotation of the primary rear cover exhaust assembly enables precise cooling of the pump core, and the rotation of the secondary exhaust assembly enables secondary cooling of the pump body. This dual cooling ensures that the pump can run dry without media cooling. Attached Figure Description

[0050] In a preferred embodiment, please refer to Figure 7 The secondary exhaust assembly 500 includes an exhaust arm ring 501, with an exhaust shaft impeller 502 and an exhaust toothed ring 503 fixedly mounted at both ends of the exhaust arm ring 501.

[0051] In this embodiment, the secondary exhaust assembly 500 is located within the exhaust channel 107.

[0052] In this embodiment, the exhaust arm ring 501 is rotatably mounted on the inner wall of the exhaust groove 107 via a bearing.

[0053] In this embodiment, the exhaust arm ring 501 is sleeved on the outside of the exhaust pipe 104.

[0054] In this embodiment, the exhaust tooth ring 503, the exhaust gear 402, and the pressure stabilizing gear 308 are located on the same longitudinal plane.

[0055] In this embodiment, the pressure stabilizing gear 308 is located between the exhaust gear ring 503 and the exhaust gear 402.

[0056] In this embodiment, a planetary gear meshing structure is formed between the exhaust gear 402, the pressure stabilizing gear 308, and the exhaust gear ring 503, which rotate synchronously.

[0057] The working principle of this invention is as follows: When a magnetic pump is in use, the introduction of gas into the pump can cause cavitation, resulting in pitting corrosion or even spalling of the pump body, impeller, volute, and other flow-through components, reducing the pump's service life. Simultaneously, gas occupying the pump's internal space leads to a significant decrease in flow rate and head, failing to meet operational requirements. It also causes pump vibration, increased noise, and damages the stability of the shaft system, thus affecting the transmission efficiency of the magnetic coupler. However, existing methods of directly venting the pump body during exhaust cause an increase in internal volume and unstable internal pressure. To address these issues, this invention provides a pressure stabilizing chamber assembly 200 in the middle of the magnetic pump assembly 100. The pressure stabilizing chamber assembly 200 has rotatably mounted pressure stabilizing arm assemblies 300 at both the top and bottom. In actual use, one set of stabilizing arm assemblies... The pressure arm assembly 300 rotates within the first pressure stabilizing chamber 202, while another pressure stabilizing arm assembly 300 rotates within the second pressure stabilizing chamber 208. The through-pipe 203 on the first pressure stabilizing chamber 202 is connected to an external storage device via a pipe, and the through-pipe 203 on the second pressure stabilizing chamber 208 is connected to an external media storage device via a pipe. In actual use, both pressure stabilizing arm assemblies 300 rotate synchronously within the first and second pressure stabilizing chambers 202 and 208. When one pressure stabilizing arm assembly 300 rotates within the first pressure stabilizing chamber 202, the pressure stabilizing ring roller 302 is rotatably positioned within the first C-shaped pressure stabilizing groove 204. The pressure stabilizing ring roller 302 is sleeved outside the guide rail concave wheel 205. The tension spring 306 tightens the contact piston 305, and the roller 303 at the bottom of the contact rod 304... The pressure stabilizing ring roller 302 abuts against the concave roller 205. Because the concave roller 205 has a concave structure, when the pressure stabilizing ring roller 302 rotates within the first C-shaped pressure stabilizing groove 204, the roller 303 at the bottom of the abutting rod 304 rolls around the concave roller 205. As the roller 303 travels along the concave structure at the bottom of the concave roller 205, the tension spring 306 pulls the abutting piston 305 towards the inside of the pressure stabilizing seat groove 307. At this time, an air extraction structure is formed inside the pressure stabilizing seat groove 307. When the pressure stabilizing ring roller 302 continues to rotate, and the roller 303 travels to the protruding structure of the concave roller 205, the abutting rod 304 drives the abutting piston 305 towards the outside of the pressure stabilizing seat groove 307, thus achieving an exhaust structure within the pressure stabilizing seat groove 307. In this way, the pressure stabilizing ring roller 302 rotates within the first C-shaped pressure stabilizing groove 204. When the pressure-stabilizing ring roller 302 rotates outside the guide rail concave wheel 205, it voluntarily achieves air extraction and exhaust within the pressure-stabilizing seat groove 307. Simultaneously, when another set of pressure-stabilizing arm assemblies 300 rotates within the second pressure-stabilizing chamber 208, the pressure-stabilizing ring roller 302 is rotatably positioned within the second C-shaped pressure-stabilizing groove 207. The pressure-stabilizing ring roller 302 is sleeved outside the guide rail cam 206. Through the tension spring 306 tightening the abutment piston 305, the roller 303 at the bottom of the abutment rod 304 abuts against the guide rail cam 206. Since the guide rail cam 206 has a convex structure, when the pressure-stabilizing ring roller 302 rotates within the second C-shaped pressure-stabilizing groove 207, the roller 303 at the bottom of the abutment rod 304 rolls around the guide rail cam 206. As the roller 303 travels on the convex structure at the top of the guide rail cam 206...The contact rod 304 drives the contact piston 305 to move outward from the pressure stabilizing seat groove 307, thus forming a drainage structure within the pressure stabilizing seat groove 307. When the pressure stabilizing ring roller 302 continues to rotate, and the roller 303 travels to the non-protruding structure of the guide cam 206, the contact rod 304 drives the contact piston 305 to move inward from the pressure stabilizing seat groove 307, thus forming a pumping structure within the pressure stabilizing seat groove 307. In this way, when the pressure stabilizing ring roller 302 in the second C-shaped pressure stabilizing groove 207 rotates outside the guide cam 206, it accordingly realizes the pumping and drainage actions within the pressure stabilizing seat groove 307. In this design, the pressure-stabilizing arm assembly 300 inside the first pressure-stabilizing chamber 202 extracts gas from the pump housing 101, while the pressure-stabilizing arm assembly 300 inside the second pressure-stabilizing chamber 208 fills the pump housing 101 with liquid. Since the two pressure-stabilizing arm assemblies 300 rotate synchronously, the venting and filling of the pump housing 101 are performed simultaneously. This structure allows for simultaneous venting of the magnetic pump assembly 100 and filling of the venting space with liquid, preventing drastic pressure fluctuations within the pump caused by changes in the venting space during venting.

[0058] Based on the above, in order to achieve synchronous driving of multiple sets of voltage stabilizing arm assemblies 300, the rear end of the magnetic pump assembly 100 of the present invention is provided with a primary rear cover exhaust assembly 400 and a secondary exhaust assembly 500. The primary rear cover exhaust assembly 400 is connected to the output shaft inside the magnetic pump assembly 100. A planetary gear meshing structure is formed between the voltage stabilizing arm assembly 300, the primary rear cover exhaust assembly 400, and the secondary exhaust assembly 500. Specifically, one end of the exhaust shaft 401 is fixedly connected to the impeller 110 shaft. The exhaust gear ring 503, the exhaust gear 402, and the voltage stabilizing gear 308 of the present invention are on the same longitudinal plane, and the voltage stabilizing gear 308 is located on the exhaust gear ring 503. Between the exhaust gear 402 and the pressure stabilizing gear 308, a planetary gear meshing structure is formed between the exhaust gear 402, the pressure stabilizing gear 308, and the exhaust gear ring 503. In actual use, one side of the pressure stabilizing gear 308 meshes with the exhaust gear ring 503, and the other side of the pressure stabilizing gear 308 meshes with the exhaust gear 402. Through this structure, the first-stage rear cover exhaust assembly 400 is driven when the magnetic pump assembly 100 starts. At the same time, through the above-mentioned planetary gear meshing structure, the pressure stabilizing arm assembly 300, the first-stage rear cover exhaust assembly 400, and the second-stage exhaust assembly 500 are driven synchronously.

[0059] Based on the above, while the primary exhaust assembly 400 and the secondary exhaust assembly 500 are driven synchronously, the rotation of the primary exhaust assembly 400 at the rear end of the magnetic pump assembly 100 achieves primary exhaust heat dissipation during dry running of the magnetic pump assembly 100. Similarly, the rotation of the secondary exhaust assembly 500 achieves secondary exhaust heat dissipation during dry running of the magnetic pump assembly 100. Specifically, when the primary exhaust assembly 400 rotates, the air generated by the exhaust fan blades 403 on the primary exhaust assembly 400 is discharged through the exhaust pipe 105 to the core isolation sleeve of the pump housing 101, providing targeted heat dissipation to the core isolation sleeve and enabling continuous operation of the pump under dry running conditions without medium cooling. Simultaneously, this invention, through the aforementioned planetary meshing structure, synchronously achieves secondary exhaust assembly... The secondary exhaust assembly 500 is mounted outside the primary rear cover exhaust assembly 400. When the secondary exhaust assembly 500 rotates, the cooling air generated by the exhaust shaft impeller 502 enters the conical air shroud 106 through the exhaust groove 107. The conical air shroud 106 blows the air generated by the secondary exhaust assembly 500 toward the pump body, achieving secondary pump body cooling. In summary, through the above-mentioned planetary meshing structure, the primary rear cover exhaust assembly 400 and the secondary exhaust assembly 500 rotate synchronously while multiple sets of pressure stabilizing arm assemblies 300 rotate synchronously. The rotation of the primary rear cover exhaust assembly 400 achieves precise cooling of the pump core, and the rotation of the secondary exhaust assembly 500 achieves secondary cooling of the pump body. This dual cooling ensures that the pump can run dry without medium cooling.

[0060] It should be noted that the air outlet of the exhaust pipe 105 can be designed with other structures.
