Description

Technical Field

[0001] This utility model relates to the field of general mechanical manufacturing technology, specifically to a pump body with a quick-replaceable mechanical seal. Background Technology

[0002] As the core equipment for fluid transportation, pumps are widely used in many industrial scenarios such as petrochemicals, water treatment, energy, and pharmaceuticals. Their operational stability and sealing performance are directly related to production efficiency, fluid transportation safety, and environmental protection. As a key component for preventing leakage in pumps, the reliability and ease of maintenance of mechanical seals have always been core issues of concern in the industry.

[0003] Traditional pump bodies often rely on a single bolt for flange connection, lacking a precise positioning structure. During assembly, the flange position needs to be repeatedly adjusted to align with the mounting holes. Existing sealing solutions mostly use a single sealing ring structure, with the sealing ring material often being ordinary rubber or metal, which is prone to problems such as material aging, corrosion, and deformation, leading to seal failure and fluid leakage. Although some improved solutions attempt to add auxiliary sealing structures, they suffer from poor compatibility of component materials. In addition, the mechanical seal components of traditional pump bodies are mostly integrated with the flange or use a complex connection method, requiring the disassembly of the main pump body structure when replacing the seal.

[0004] In summary, the current technical deficiencies of mechanical seals for pump bodies in terms of disassembly and assembly efficiency, sealing reliability, and maintenance costs can no longer meet the modern industrial demand for efficient, stable, and low-maintenance pump equipment. Therefore, developing a mechanical seal pump body with rapid positioning and assembly, dual high-efficiency sealing, and convenient maintenance has become an urgent technical problem to be solved in the field of general machinery manufacturing.

The cylindrical positioning protrusions and positioning grooves are precisely aligned and fixed with the bolts in the mating holes, which quickly realizes the positioning and assembly of the two sets of flanges, providing a basis for the rapid replacement of mechanical seals and shortening the disassembly and assembly time.

[0030] Example 1

[0031] like Figures 1 to 3As shown, this embodiment provides a pump body with a quick-replacement mechanical seal, comprising: a flange 1 for supporting components; a connecting component including a power input end 2 arranged on one side of flange 1, and a flange 2 3 that mates with flange 1; a positioning component including positioning protrusions 5 arranged on one side of flange 1, wherein the positioning protrusions 5 are provided in two sets and are cylindrical in shape, and also including mating holes 7 opened on flange 1 and flange 2 3, wherein the two sets of mating holes 7 are connected by bolts; a storage component including an air bladder 8 arranged on flange 1; and a sealing component including a sealing ring 10 arranged on flange 1, wherein the sealing ring 10 is made of fluororubber.

[0032] Understandable Figure 1 The mechanical seal pump body only schematically illustrates some of its components; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, pump bodies with mechanical seals can also include, compared to... Figure 1 More or fewer parts.

[0033] Furthermore, in this embodiment, each component is supported by flange 1, and flange 1 and flange 2 are connected and fixed by mating holes 7 and bolts. Positioning protrusions 5 assist in positioning, sealing rings 10 achieve sealing, airbags 8 store gas, and power input end 2 is connected to power, thereby realizing the assembly and basic sealing of each component of the pump body, laying the structural foundation for subsequent rapid replacement of mechanical seals.

[0034] Specifically, the connection assembly includes a fluid delivery end 4, which is arranged on one side of flange 2 3.

[0035] In this embodiment, the power input terminal 2 receives power to drive the pump body to operate, and the fluid is transported through the fluid delivery terminal 4, thus improving the function of the connecting components and ensuring the normal operation of the pump body power input and fluid delivery.

[0036] Specifically, the positioning component includes a positioning groove 6, which is formed on the flange 2 3 and cooperates with the positioning protrusion 5.

[0037] As a preferred implementation method, during assembly, the positioning protrusion 5 on flange 1 is embedded into the positioning groove 6 on flange 2, achieving precise positioning of the two. Then, they are fixed by the mating hole 7 and bolts, which improves the mating accuracy of flange 1 and flange 2, reduces assembly deviation, and ensures the stability of pump operation.

[0038] Example 2

[0039] Specifically, the storage component includes: an air supply pipe 9, one end of which is connected to the airbag 8, and the other end is connected to the sealing ring 10 and snapped onto the flange 1.

[0040] In this embodiment, the gas stored in the airbag 8 is delivered to the sealing ring 10 through the gas delivery pipe 9, providing auxiliary pressure to the sealing ring 10, realizing gas transmission, enhancing the sealing performance of the sealing ring 10, and reducing the risk of fluid leakage.

[0041] Specifically, the sealing assembly includes a groove 11, which is formed on the flange 2 3 and cooperates with the sealing ring 10.

[0042] With this configuration, when flange 1 and flange 2 (3) are connected, the sealing ring 10 is embedded in the groove 11 of flange 2 (3), and combined with the gas pressure delivered by the gas pipe 9, a double seal is formed, which further enhances the sealing effect of the pump body and effectively prevents fluid leakage at the flange connection.

[0043] Example 3

[0044] Specifically, the airbag 8 is made of nitrile rubber.

[0045] Specifically, the gas pipe 9 is made of nylon.

[0046] In actual use, when the pump body with the mechanical seal needs to be replaced, the user loosens the bolts connecting flange 1 and flange 2 3 and separates flange 1 and flange 2 3. The compressed air bladder 8 and the gas inside the sealing ring 10 circulate. The air bladder 8, the air supply pipe 9, and the sealing ring 10 are sealed inside. Then, the user can remove the air supply pipe 9 that is clipped onto flange 1 and replace it with a new one. Then, with the cooperation of the positioning protrusion 5 and the positioning groove 6, flange 1 and flange 2 3 are connected. The air bladder 8 is compressed on one side of flange 2 3, so the gas inside the air bladder 8 is delivered to the sealing ring 10 through the air supply pipe 9. After the sealing ring 10 is inflated, it fits against the groove 11 to form a seal.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
