Description

Technical Field

[0001] The invention relates to the technical field of hot water pumps, in particular to an air cooling device for a hot water pump bearing body. Background Art

[0002] In a hot water pump, a rotating shaft passes through the bearing body, which is connected to the bearing body and is connected to a connecting pipe. One end of the rotating shaft is fixed to the power output shaft of the motor, and the other end passes through the bearing body and the connecting pipe and extends into the impeller cavity of the pump body. The bearing body is equipped with a mechanical seal to prevent hot water in the impeller cavity from flowing out through the connecting pipe and the bearing body. During operation of the hot water pump, hot water entering the impeller cavity will bring a great deal of heat to the impeller cavity. At the same time, hot water will flow through the impeller cavity and the connecting pipe to the mechanical seal on the bearing body, where it will be blocked by the mechanical seal, causing the temperature of the connecting pipe and the mechanical seal to rise.

[0003] At present, the main heat dissipation method is to set a number of heat sinks on the connecting pipe body, but this method has poor heat dissipation effect, affecting the efficiency of cooling and heat dissipation, thereby affecting the service life of the mechanical seal and the overall working stability of the hot water pump. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A hot water pump bearing body air cooling device includes a pump body, the top of which is fixedly connected to a protective frame;

[0005] A motor and a frame fixedly mounted on the bottom of the motor, wherein one end of the frame away from the motor is fixedly connected to the top of the protective frame;

[0006] A connecting component, the connecting component is fixedly connected to the output end of the motor;

[0007] A rotating member is fixedly connected to an end of the connecting assembly away from the motor, and an impeller is provided on the outside of the rotating member and is located inside the pump body;

[0008] The heat dissipation mechanism is a series of heat dissipation mechanisms, wherein the ... The outer side of the heat sink is provided with through holes, and there are multiple through holes. The multiple through holes are divided into multiple groups. The through holes in a group are evenly arranged in the radial direction of the heat sink. The through holes are arranged from small to large in diameter from the shaft toward the edge of the heat sink. The through holes allow air to flow freely between the heat sinks, dispersing heat to the surrounding environment in a timely manner, avoiding excessive temperatures in any one area, ensuring uniform temperature distribution on the surface of the bearing body, and effectively extending the service life of the bearing. At the same time, the uniform arrangement of the through holes from small to large can effectively regulate the air flow rate and flow rate. The small diameter through holes near the heat source of the shaft accelerate the air flow rate when passing through, quickly removing heat near the shaft. As the through hole diameter gradually increases, the air flow rate increases, ensuring that heat is fully diffused at the edge of the heat sink. This design avoids the problem of uneven air flow within the heat sink, making heat transfer more efficient and uniform. At the same time, the gradual change in the through hole diameter design makes the air flow within the heat sink smoother, reducing turbulence caused by sudden changes in the aperture. The smooth airflow not only helps to improve heat dissipation efficiency, but also reduces the noise generated by air flow, improving the comfort of the hot water pump operating environment.

[0009] Preferably, the rotating part is located inside the protective frame, and the rotating part passes through the pump body and extends to the inside, and a trapezoidal block is fixedly connected to the inner wall of the frame near one end of the protective frame. There are multiple trapezoidal blocks, and the multiple trapezoidal blocks are evenly distributed inside the frame. A filter plate is fixedly connected to the inside of the protective frame. By arranging the filter plate on the protective frame, the filter plate can intercept dust, gravel, fiber and other impurities in the air to prevent them from entering the through holes of the heat sink and the inside of the bearing body, thereby preventing impurities from accumulating on the surface of the heat sink or clogging the through holes, ensuring smooth air circulation, maintaining stable heat dissipation efficiency, and avoiding the decline in heat dissipation performance due to dust accumulation. At the same time, by filtering impurities, the cleaning frequency of the heat sink and the through holes is reduced, the service life of the heat sink is extended, and the interference of frequent maintenance on the normal operation of the equipment is reduced. There are multiple filter plates, and the multiple filter plates are evenly distributed inside the protective frame.

[0010] The fan is rotated by the outer cover of the fan shaft, and the outer cover of the fan is rotated by the outer cover of the fan shaft, so that the fan shaft rotates and the fan rotates. The rotation of the fan drives the air flow. At this time, the heat dissipation plate below the fan can guide the air flow to spread evenly, avoiding local uneven heat dissipation caused by chaotic airflow, improving the overall heat dissipation effect, and quickly taking away the heat near the fan through air flow to prevent problems with the fan caused by excessive temperature, thereby ensuring stable operation of the fan and extending its service life. The end of the shaft away from the connecting assembly is fixedly connected with an arc block, the arc block is located inside the pump body, the outer side of the shaft is fixedly connected to the impeller, and the fan is located above the heat dissipation plate, and the outer side of the shaft is rotatably connected to a bearing, and the outer side of the bearing is fixedly connected to a bearing seat, and the upper and lower seats are tightly connected by bolts to fix the bearing. This split structure can achieve accurate alignment of the bearing and the shaft through the precisely machined joint surface, avoiding abnormal wear of the bearing caused by installation error, ensuring the stability of the coordinated operation of the fan and the heat dissipation plate, and the design of the split bearing seat is structurally stable. The structure is more conducive to air circulation. The split joints can form a through airflow channel with the through holes of the heat sink, the square plate and the trapezoidal block. When the fan rotates, the airflow can not only take away the heat through the heat sink, but also flow through the inside of the bearing seat and the square plate outside the bearing seat to directly cool the bearing, further improving the overall heat dissipation efficiency and preventing the bearing from failing in lubrication due to high temperature.

The square plates are evenly distributed on the bearing housing, and the square plates above and below the trapezoidal blocks are staggered. This staggered layout creates a more complex and orderly path for air flowing through the square plates outside the bearing housing, avoiding localized turbulence caused by airflow through the square plates. The air forms a spiral or circuitous flow between the interlaced heat sinks, extending contact time with the heat sinks and more effectively removing heat. This airflow organization also reduces air flow resistance and reduces fan energy consumption.

The elastic ring has a certain deformation adaptability, which can make up for the dimensional error of the circular plate and the intermediate ring during the assembly process, and ensure that the components fit closely. At the same time, under the high-temperature operating conditions of the hot water pump, the metal parts will Thermal expansion and contraction cause dimensional changes. The elastic ring can dynamically compensate for this deformation by compressing or rebounding itself, maintain the stability of the structure, and prevent transmission failure caused by gap changes.

A plurality of heat sinks 63 are provided on the outer side of the rotating shaft 61. The plurality of heat sinks 63 increase the contact area with the air, accelerate the heat dissipation, and create more space for heat exchange. At the same time, through holes 64 are provided on the heat sink 63, so that the air can form a through flow between the heat sinks, optimize the air flow path, accelerate the heat transfer from the inside of the heat sink 63, reduce the eddy current and turbulence of the air on the surface of the heat sink, let the air directly contact the vicinity of the heat source, quickly take away the heat, and improve the heat exchange efficiency.

The through holes 64 in one group are evenly arranged in the radial direction of the heat sink 63. The through holes 64 are arranged from small to large in diameter from the rotating shaft 61 to the edge of the heat sink 63. The through holes 64 allow air to freely pass between the heat sinks 63, and disperse heat to the surrounding environment in time to avoid excessive temperature in a certain area, ensure that the surface temperature of the bearing body is evenly distributed, and effectively extend the service life of the bearing.

The small-diameter through holes close to the heat source of the rotating shaft 61 speed up the flow rate of air when passing through, and quickly take away the high heat near the shaft. As the through hole diameter gradually increases, the air flow increases, ensuring that the heat can also be fully diffused at the edge of the heat sink 63. This design avoids the problem of uneven air flow in the heat sink 63, making heat transfer more efficient and uniform.

The inside of the protective frame 8 is fixedly connected with a filter plate 9. By arranging the filter plate 9 on the protective frame 8, the filter plate 9 can intercept dust, gravel, fiber and other impurities in the air to prevent them from entering the through holes 64 of the heat sink 63 and the inside of the bearing body, thereby preventing impurities from accumulating on the surface of the heat sink 63 or clogging the through holes 64, ensuring smooth air circulation, maintaining stable heat dissipation efficiency, and avoiding the decline in heat dissipation performance due to dust accumulation. At the same time, by filtering impurities, the cleaning frequency of the heat sink 63 and the through holes 64 is reduced, the service life of the heat sink 63 is extended, and the interference of frequent maintenance on the normal operation of the equipment is reduced. There are multiple filter plates 9, and the multiple filter plates 9 are evenly distributed inside the protective frame 8.

The lower connecting cylinder 31 drives the rotating shaft 61 to rotate. The rotating shaft 61 drives the impeller 7 to rotate, so that the material enters the middle cylinder 12 through the feed pipe 13 and the connecting pipe 14. Then the material is discharged from the discharge pipe 15 as the impeller 7 rotates. The connecting pipe 14 is located inside the end of the feed pipe 13. The top of the middle cylinder 12 is fixedly connected to the protective frame 8. The middle of the interior of the middle cylinder 12 is rotatably connected to the shaft sleeve 17. The shaft sleeve 17 is located in the middle cylinder 1 2 is close to the side of the protective frame 8, and the shaft sleeve 17 passes through the intermediate cylinder 12.

A groove is provided on the side of the intermediate cylinder 12 close to the protrusion. The fixing plate 16 and the intermediate cylinder 12 form a sealing structure through the protrusion and the groove. The sealing structure can effectively prevent the leakage of the medium and ensure the stable circulation of hot water in the pump body. The sealing structure can also prevent external dust, particles, water vapor and other impurities from entering the pump body 1, which can avoid the wear and corrosion of precision components by impurities, reduce equipment failures caused by impurities, and extend the service life of the hot water pump.

An intermediate ring 36 is provided in the middle of the inner part of the cylinder 32. Elastic rings are provided at both ends of the intermediate ring 36.

The elastic ring has a certain degree of deformation adaptability, which can make up for the dimensional error of the circular plate 33 and the intermediate ring 36 during the assembly process, ensuring a close fit between the components. At the same time, under the high-temperature operating conditions of the hot water pump, the metal components will expand and contract due to heat.

There are multiple card slots 39, and the multiple card slots 39 Evenly distributed inside the intermediate ring 36, the gear ring 38 is engaged with the intermediate ring 36 through the groove 39. The gear meshing transmits torque through direct engagement between the gear teeth, which has higher transmission efficiency and less power loss. This design can ensure the precise transmission of power between the rotating shaft 61 and the output end of the motor 2, reduce energy loss caused by slipping and idling, and the gear meshing structure has a certain buffering performance. When the system starts, stops or the load suddenly changes, the involute tooth profile of the gear teeth can effectively absorb impact and vibration, avoiding instantaneous overload on the rotating shaft, bearings and other components. An intermediate plate 310 is fixedly connected to the middle of the inner wall of the intermediate ring 36, and the vertical ends of the intermediate plate 310 are in contact with the end faces of the two gear rings 38 away from the circular plate 33.

[0040] When in use, the motor 2 is connected to an external power supply and works. The motor 2 drives the circular plate 33 to rotate through the upper connecting tube 31. The circular plate 33 drives the lower connecting tube 31 to rotate through the bottom gear ring 38 and the middle ring 36, so that the lower connecting tube 31 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the impeller 7 to rotate, so that the material enters the middle tube 12 through the feed pipe 13 and the connecting tube 14. Then, the material is discharged from the discharge pipe 15 as the impeller 7 rotates. At the same time, the rotating shaft 61 drives the fan 65 to rotate, and the rotation of the fan 65 drives the flow of air. At this time, the heat dissipation plate 63 below the fan 65 can guide the airflow to diffuse evenly, and the through hole The diameters of the through holes 64 are arranged from small to large from the rotating shaft 61 to the edge of the heat sink 63. The through holes 64 allow air to freely pass through the heat sink 63, dispersing heat to the surrounding environment in a timely manner, avoiding excessive temperature in a certain area, ensuring uniform temperature distribution on the surface of the bearing body, and effectively extending the service life of the bearing. At the same time, the through holes 64 are evenly arranged from small to large, which can effectively adjust the air flow rate and flow. The small-diameter through holes close to the heat source of the rotating shaft 61 speed up the flow rate of air passing through, quickly taking away the high heat near the shaft. As the diameter of the through holes gradually increases, the air flow rate increases, ensuring that the heat can also be fully diffused at the edge of the heat sink 63.
