Description

Technical Field

[0001] This utility model relates to the field of pump equipment technology, and in particular to a pump bearing housing and pump equipment. Background Technology

[0002] Centrifugal or axial pumps are common fluid transport devices in industrial fields. Their core components include the pump body, pump cover, impeller, shaft, and bearing housing. The primary function of the bearing housing is to stably support the rotating shaft and provide lubrication through internal lubricating oil, ensuring the smooth transmission of torque across the entire rotor. To guarantee the long-term reliable operation of the bearings and the entire rotor, the bearing housing must possess excellent heat dissipation performance to prevent mechanical failures or efficiency reduction due to excessive temperature. In existing technologies, bearing housing heat dissipation typically involves using an external fan to direct airflow across the outer surface of the bearing housing to accelerate heat dissipation; or introducing cooling water for heat exchange to achieve efficient cooling. However, in situations where cooling water supply is lacking or the fan is malfunctioning, especially in high ambient temperature applications, existing heat dissipation methods struggle to further improve performance, limiting the pump's performance under extreme conditions. Therefore, improving the heat dissipation effect of the bearing housing has become a pressing technical problem to be solved. Utility Model Content

[0004] The above-mentioned objective of this utility model can be achieved by the following technical solution: This utility model provides a pump bearing housing, comprising:

[0005] The housing structure includes a housing with a lubricating oil chamber and a heat dissipation opening disposed on the housing, the heat dissipation opening communicating with the lubricating oil chamber;

[0006] A heat dissipation component is connected to the housing and covers the heat dissipation opening. The thermal conductivity of the heat dissipation component is higher than that of the housing.

[0007] In a preferred embodiment of the present invention, the heat dissipation component includes a heat-conducting substrate and a first heat dissipation structure and a second heat dissipation structure respectively disposed on both end faces of the heat-conducting substrate. The heat-conducting substrate is connected to the housing and covers the heat dissipation opening. At least a portion of the first heat dissipation structure is inserted into the lubricating oil cavity, and the second heat dissipation structure is disposed on the outside of the housing.

[0008] In a preferred embodiment of the present invention, the pump bearing housing further includes a sealing structure disposed between the housing body and the heat-conducting substrate. The sealing structure includes a sealing groove disposed on the housing body around the heat dissipation opening, and a sealing ring disposed in the sealing groove and abutting against the heat-conducting substrate.

[0009] In a preferred embodiment of this utility model, the thermally conductive substrate is detachably connected to the housing.

[0010] In a preferred embodiment of the present invention, the heat-conducting substrate is provided with a plurality of first mounting holes, the housing is provided with a plurality of second mounting holes that match the first mounting holes, and the pump bearing housing further includes a plurality of connecting bolts, which are used to connect the corresponding first mounting holes and second mounting holes.

[0011] In a preferred embodiment of the present invention, the first heat dissipation structure includes a plurality of first heat dissipation fins, which are arranged sequentially at intervals, and the first heat dissipation fins are rectangular or corrugated; or, the first heat dissipation structure includes a plurality of first heat dissipation fins, which are arranged in an array to form a first heat dissipation fin array, with the first heat dissipation fins in the same row arranged at intervals, and the projections of the first heat dissipation fins in adjacent rows in the direction perpendicular to the first heat dissipation fins do not overlap.

[0015] This utility model also provides a pump device, including the aforementioned pump bearing housing.

[0016] The technical solution of this utility model has the following significant beneficial effects:

[0017] The pump bearing housing described in this invention enhances its heat dissipation capacity by incorporating heat dissipation openings on the housing and connecting heat dissipation components with a thermal conductivity higher than that of the housing. This is particularly effective in situations where cooling water supply is lacking or the fan is malfunctioning, thus better ensuring the performance of the pump equipment.

[0018] Specifically, the heat dissipation components can be placed inside the lubricating oil chamber through heat dissipation openings. These components then conduct heat from the lubricating oil chamber to the external environment, effectively reducing the internal temperature of the enclosure.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Implementation Method 1

[0040] Please refer to the following: Figures 1 to 11 As shown, an embodiment of the present invention provides a pump bearing housing, which includes a housing structure 100 and a heat dissipation component 200. The housing structure 100 includes a housing 110 having a lubricating oil cavity 111 and a heat dissipation opening 120 disposed on the housing 110, the heat dissipation opening 120 communicating with the lubricating oil cavity 111; the heat dissipation component 200 is connected to the housing 110 and covers the heat dissipation opening 120, and the thermal conductivity of the heat dissipation component 200 is higher than that of the housing 110.

[0041] Overall, such as Figure 3 In the illustrated embodiment, the pump bearing housing enhances its heat dissipation capacity by providing a heat dissipation opening 120 on the housing 110 and connecting a heat dissipation component 200 with a thermal conductivity higher than that of the housing 110. The heat dissipation component 200 further enhances the heat dissipation capacity of the pump bearing housing. Especially in situations where cooling water supply is lacking or the fan is not operating normally, the heat dissipation effect of this invention is more pronounced, thereby better ensuring the performance of the pump equipment.

[0042] Specifically, such as Figure 1 and Figure 2 In the illustrated embodiment, the heat dissipation component 200 can be placed inside the lubricating oil cavity 111 through the heat dissipation opening 120. The heat dissipation component 200 then conducts heat from the lubricating oil cavity 111 to the external environment, effectively reducing the internal temperature of the enclosure 110. Furthermore, the high thermal conductivity material of the heat dissipation component 200, such as aluminum alloy or copper / copper alloy, has better heat conduction efficiency than the cast iron or carbon steel material used in the enclosure, thus improving heat dissipation efficiency.

[0043] Furthermore, the heat dissipation component 200 eliminates the need for an additional power source (such as a fan or cooling water system), reducing manufacturing and operating costs and avoiding leakage problems that may arise from complex casting structures, further saving on maintenance and repair costs. Moreover, the combined design of the housing 110 and the heat dissipation component 200 allows different models of pump equipment to use the same heat dissipation component 200, improving the commonality of parts and reducing the complexity of production management.

[0044] In the embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10In the embodiment shown, the heat dissipation component 200 includes a heat-conducting substrate 210 and a first heat dissipation structure 220 and a second heat dissipation structure 230 respectively disposed on the two end faces of the heat-conducting substrate 210. The heat-conducting substrate 210 is connected to the housing 110 and covers the heat dissipation opening 120. At least a portion of the first heat dissipation structure 220 is inserted into the lubricating oil cavity 111, and the second heat dissipation structure 230 is disposed on the outside of the housing 110.

[0045] By providing a first heat dissipation structure 220 and a second heat dissipation structure 230 on both sides of the thermally conductive substrate 210, the heat dissipation performance is further enhanced by utilizing the first heat dissipation structure 220 and the second heat dissipation structure 230.

[0046] Specifically, by inserting the first heat dissipation structure 220 into the lubricating oil cavity 111, the first heat dissipation structure 220 directly contacts the high-temperature lubricating oil. The first heat dissipation structure 220 can quickly absorb heat and conduct it to the second heat dissipation structure 230 through the high thermal conductivity thermally conductive substrate 210. The second heat dissipation structure 230 is located on the outside of the housing 110, increasing the contact area with the air and effectively dissipating heat into the atmospheric environment.

[0047] In the embodiments of this utility model, such as Figure 11 The embodiment shown further includes a sealing structure 300 disposed between the housing 110 and the heat-conducting substrate 210. The sealing structure 300 includes a sealing groove 310 disposed on the housing 110 surrounding the heat dissipation opening 120, and a sealing ring 320 disposed in the sealing groove 310 and abutting against the heat-conducting substrate 210.

[0048] By setting a sealing structure 300 between the housing 110 and the heat-conducting substrate 210, the problem of lubricating oil leakage under high-temperature conditions is effectively solved.

[0049] Specifically, the sealing ring 320 is embedded in the sealing groove 310 on the housing 110 and closely abuts against the heat-conducting substrate 210, forming a reliable sealing barrier. This prevents lubricating oil from leaking from the heat dissipation opening 120 and also prevents external impurities from entering the lubricating oil cavity 111 and affecting the bearing operation. This improves the overall sealing performance and reliability of the pump bearing housing, ensures that the pump equipment can operate stably for a long time in a high-temperature environment, and further enhances the practicality and market competitiveness of the pump equipment.

[0050] In the embodiments of this utility model, such as Figure 1 In the illustrated embodiment, the thermally conductive substrate 210 is detachably connected to the housing 110. By detachably connecting the thermally conductive substrate 210 to the housing 110, the ease of maintenance of the pump bearing housing and the efficiency of replacing the heat dissipation component 200 are significantly improved.

[0051] Specifically, when the heat dissipation component 200 is worn or damaged, it is not necessary to replace the entire pump bearing housing; only the heat dissipation component 200 needs to be disassembled and replaced, thereby reducing maintenance costs and time.

[0052] Designers can adjust the detachable connection between the heat-conducting substrate 210 and the housing 110 according to usage requirements, without specific limitations. Preferably, the heat-conducting substrate 210 is provided with a plurality of first mounting holes, and the housing 110 is provided with a plurality of second mounting holes that match the first mounting holes. The pump bearing housing also includes a plurality of connecting bolts 400, which are used to connect the corresponding first mounting holes and second mounting holes.

[0053] By setting matching first mounting holes and second mounting holes on the heat-conducting substrate 210 and the housing 110 respectively, and fixing them with connecting bolts 400, a stable and precise detachable connection between the heat-conducting substrate 210 and the housing 110 is achieved, ensuring the structural stability between the heat-conducting substrate 210 and the housing 110, and avoiding loosening problems caused by vibration or high temperature.

[0054] In the embodiments of this utility model, the designer may adjust the specific structure of the first heat dissipation structure 220 according to the needs of use, and no specific restrictions are imposed here.

[0055] In one feasible embodiment, such as Figure 4 In the illustrated embodiment, the first heat dissipation structure 220 includes a plurality of first heat dissipation fins 221, which are arranged sequentially at intervals and are rectangular in shape. Specifically, the first heat dissipation fins 221 extend along the axial direction of the housing 110, and the plurality of first heat dissipation fins 221 are arranged at intervals in a direction perpendicular to the axial direction of the housing 110.

[0056] In another feasible embodiment, such as Figure 5 In the illustrated embodiment, the first heat dissipation structure 220 includes a plurality of first heat dissipation fins 221, which are arranged sequentially at intervals and are corrugated. Specifically, the first heat dissipation fins 221 are corrugated along the axial direction of the housing 110, and the plurality of first heat dissipation fins 221 are arranged at intervals along a direction perpendicular to the axial direction of the housing 110.

[0057] The corrugated design increases the surface area of ​​the first heat dissipation fin 221, thereby enhancing its heat absorption performance and heat transfer efficiency. Furthermore, the corrugated shape guides fluid flow, creating a turbulent effect that further improves heat dissipation and reduces thermal resistance.

[0058] Designers can adjust the size of the corrugated first heat dissipation fin 221 according to the usage requirements, without specific limitations. Preferably, the wavelength of the corrugated first heat dissipation fin 221 is 3mm to 60mm, and the amplitude is 1.5mm to 10mm.

[0059] In another feasible embodiment, such as Figure 6 In the embodiment shown, the first heat dissipation structure 220 includes a plurality of first heat dissipation fins 221, which are arranged in an array to form a first heat dissipation fin array 221. The first heat dissipation fins 221 in the same row are arranged at intervals, and the projections of the first heat dissipation fins 221 in adjacent rows in the direction perpendicular to the first heat dissipation fin 221 do not overlap.

[0060] With multiple staggered first heat dissipation fins 221, the gaps between adjacent first heat dissipation fins 221 can all serve as lubricating oil flow paths, optimizing the contact area between each first heat dissipation fin 221 and the lubricating oil, so that heat can be transferred from the lubricating oil to the first heat dissipation fins 221 more quickly and evenly.

[0061] Furthermore, the multiple staggered first heat dissipation fins 221 form a more complex flow path, which avoids the problem of local heat accumulation caused by poor flow of lubricating oil in the housing 110, effectively reduces the working temperature of the lubricating oil, extends the service life of the lubricating oil, and ensures the operational reliability of the pump bearing housing under high temperature conditions, reducing the risk of mechanical wear and failure caused by overheating.

[0062] Designers can adjust the size of the first heat dissipation fin 221 according to usage requirements, without specific limitations. Preferably, the thickness of the first heat dissipation fin 221 is 0.5mm to 1.2mm. The height of the first heat dissipation fin 221 is 5mm to 30mm. Furthermore, the spacing between two adjacent first heat dissipation fins 221 is 3mm to 15mm. More preferably, the minimum distance between the first heat dissipation fin 221 and the edge of the thermally conductive substrate 210 is greater than 20mm to facilitate installation.

[0063] In the embodiments of this utility model, the designer may adjust the specific structure of the second heat dissipation structure 230 according to the needs of use, and no specific restrictions are imposed here.

[0064] In one feasible embodiment, such as Figure 7 In the illustrated embodiment, the second heat dissipation structure 230 includes a plurality of second heat dissipation fins 231, which are arranged sequentially at intervals and are rectangular in shape. Specifically, the second heat dissipation fins 231 extend along the axial direction of the housing 110, and a plurality of first heat dissipation fins 221 are arranged at intervals along a direction perpendicular to the axial direction of the housing 110.

[0065] In another feasible embodiment, such as Figure 8 In the illustrated embodiment, the second heat dissipation structure 230 includes a plurality of second heat dissipation fins 231, which are arranged sequentially at intervals and are corrugated. Specifically, the second heat dissipation fins 231 are corrugated along the axial direction of the housing 110, and the plurality of second heat dissipation fins 231 are arranged at intervals along a direction perpendicular to the axial direction of the housing 110.

[0066] The corrugated design increases the surface area of ​​the second heat sink 231, thereby enhancing its heat dissipation performance and heat conduction efficiency. Furthermore, the corrugated shape guides airflow, creating a turbulent effect that further improves heat dissipation and reduces thermal resistance.

[0067] Designers can adjust the size of the corrugated second heat dissipation fin 231 according to the usage requirements, and no specific limitation is made here. Preferably, the wavelength of the corrugated second heat dissipation fin 231 is 3mm to 60mm, and the amplitude is 1.5mm to 10mm.

[0068] In another feasible embodiment, such as Figure 9 In the embodiment shown, the second heat dissipation structure 230 includes a plurality of second heat dissipation fins 231, which are arranged in an array to form a second heat dissipation fin array 231. The second heat dissipation fins 231 in the same row are arranged at intervals, and the projections of the second heat dissipation fins 231 in adjacent rows in the direction perpendicular to the second heat dissipation fin 231 do not overlap.

[0069] By using multiple staggered second heat dissipation fins 231, the gaps between adjacent second heat dissipation fins 231 can all serve as airflow paths, optimizing the contact area between each second heat dissipation fin 231 and the air, allowing heat to be dissipated to the external environment more quickly and evenly. Furthermore, the multiple staggered second heat dissipation fins 231 form a more complex airflow path, avoiding the problem of localized heat accumulation caused by poor airflow, and significantly improving heat dissipation efficiency.

[0070] Designers can adjust the dimensions of the second heat dissipation fin 231 according to usage requirements, without specific limitations. Preferably, the thickness of the second heat dissipation fin 231 is 0.5mm to 1.2mm. The height of the second heat dissipation fin 231 is 5mm to 30mm. Furthermore, the spacing between two adjacent second heat dissipation fins 231 is 3mm to 15mm.

[0071] In the embodiments of this utility model, such as Figure 10 In the illustrated embodiment, the designer can adjust the specific molding material of the heat dissipation component 200 according to the usage requirements, and no specific limitations are made here. Preferably, the heat dissipation component 200 is molded from one or more of aluminum alloy, copper, or copper alloy.

[0072] In one feasible embodiment, the heat dissipation component 200 is formed of aluminum alloy. Furthermore, the first heat dissipation fin 221, the second heat dissipation fin 231, and the thermally conductive substrate 210 can be subjected to surface anodizing treatment to improve the corrosion resistance of the heat dissipation component 200.

[0073] In another feasible embodiment, the heat dissipation component 200 is formed of copper. In yet another feasible embodiment, the heat dissipation component 200 is formed of a copper alloy. Of course, in other feasible embodiments, the heat dissipation component 200 can be formed of a combination of aluminum alloy, copper, or copper alloys.

[0074] In this field, bearing housings are typically made of cast iron or steel. While these materials possess high strength and wear resistance, their thermal conductivity is relatively poor, making it difficult to meet the requirements for efficient heat dissipation. However, using high thermal conductivity materials such as aluminum alloys, copper, and copper alloys can significantly improve heat dissipation efficiency.

[0075] Specifically, aluminum alloys possess excellent thermal conductivity and low density, enabling weight reduction while maintaining sufficient structural strength, and rapidly transferring heat to the heat dissipation structure. Copper and its alloys are renowned for their extremely high thermal conductivity, further accelerating heat transfer, reducing the operating temperature of lubricating oil and bearings, thereby improving the operational stability of pump equipment.

[0076] In the embodiments of this utility model, the designer can adjust the specific setting position of the heat dissipation opening 120 according to the usage needs, and no specific restrictions are made here.

[0077] Preferred, such as Figure 3 In the illustrated embodiment, the heat dissipation opening 120 is located at the bottom of the housing 110 and connects to the lubricating oil cavity 111. By placing the heat dissipation opening 120 at the bottom of the housing 110 and connecting it to the lubricating oil cavity 111, when the first heat dissipation structure 220 is inserted into the lubricating oil cavity 111 through the heat dissipation opening 120, the lubricating oil can collect at the location of the first heat dissipation structure 220 under the action of gravity. Thus, the first heat dissipation structure 220 can form good contact with the lubricating oil in the lubricating oil cavity 111, ensuring the stability of the heat dissipation effect.

[0078] Of course, in other feasible embodiments, the designer can adjust the specific opening position of the heat dissipation opening 120 according to the use needs. For example, the heat dissipation opening 120 is set on the side wall of the housing 110 and connected to the lubricating oil cavity 111. No specific limitation is made here.

[0079] In the embodiments of this utility model, the designer can adjust the specific shape of the heat dissipation opening 120 according to the usage requirements, and no specific limitation is made here. Preferably, the heat dissipation opening 120 is polygonal, circular, or elliptical.

[0080] In one feasible embodiment, such as Figure 3 In the embodiment shown, the heat dissipation opening 120 is rectangular. Specifically, the heat dissipation opening 120 is located at the bottom of the housing 110 and communicates with the lubricating oil cavity 111, and the heat dissipation opening 120 extends along the axial direction of the housing 110.

[0081] In another feasible embodiment, the heat dissipation opening 120 is polygonal, such as pentagonal, hexagonal, etc.

[0082] In another feasible embodiment, the heat dissipation opening 120 is circular.

[0083] In other feasible embodiments, the heat dissipation opening 120 is elliptical in shape.
