Description

Technical Field

[0001] This utility model relates to the field of petrochemical transportation technology, and in particular to a cooling device for process pumps. Background Technology

[0002] Process pumps are indispensable key equipment in the industrial field and are widely used in industries such as petrochemicals, power, metallurgy, water treatment, and pharmaceuticals. Their technical background involves multiple disciplines such as fluid mechanics, materials science, mechanical engineering, and automation control. Their main working principle is to use mechanical energy to transport liquids from low-pressure areas to high-pressure areas.

[0003] Based on their working principles and structural characteristics, process pumps can be classified into the following categories: centrifugal pumps, positive displacement pumps, axial flow pumps, and mixed flow pumps, covering multiple fields such as fluid mechanics, materials science, mechanical engineering, and automation control. With the advancement of industrial technology, process pumps are developing towards high efficiency, energy saving, intelligence, environmental protection, and customization to meet increasingly complex industrial needs.

[0004] In existing technical solutions, process pumps generate a large amount of heat during operation, requiring timely heat dissipation to prevent overheating and damage. Typically, heat dissipation plates are used on the outside of the pump casing to disperse the heat. However, pumps operating in high-temperature environments have poor heat dissipation conditions, which can easily lead to increased equipment temperature. If the external heat dissipation plates cannot continuously and efficiently cool the equipment, it can cause overheating, resulting in problems such as deterioration of material properties, lubrication failure, and seal failure, which in turn greatly affects the working efficiency of the process pump.

[0005] Therefore, a cooling device for process pumps is proposed. Utility Model Content

[0025] 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.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution:

[0027] A cooling device for a process pump includes a base plate 1. A motor 2 is fixedly connected to the upper end of the base plate 1. A pump body 21 is fixedly connected to the front end of the motor 2. A heat sink 211 is fixedly connected to the outside of the pump body 21. An air-cooling assembly 3 is provided at the rear end of the heat sink 211. The air-cooling assembly 3 includes a drive gear 31 fixedly connected to the outside of the output shaft of the motor 2. A mounting base 32 is fixedly connected to the upper end of the base plate 1. A ring 33 is fixedly connected to the upper end of the mounting base 32. A bearing 34 is fixedly connected to the outside of the ring 33. A collar 341 is fixedly connected to the outside of the bearing 34. The collar 341 is fixedly connected to the outside of the fan blade 342. The rear end of the ring 33 is movably connected to the driven gear 331. The inner wall of the collar 341 is fixedly connected to the teeth 343. The output shaft of the motor 2 is fixedly connected to the pump body 21. There are multiple fan blades 342. The driving gear 31 meshes with the driven gear 331 and the teeth 343. The collar 341 can rotate through the bearing 34. The end of the protective cover 22 near the pump body 21 is provided with a ventilation port 221. Both cover plates 4 are slidably attached to the outside of the pump body 21.

[0028] By adopting the above technical solution, when the process pump is working, the motor 2 on the base plate 1 is started to drive the fluid to flow in the pump body 21, thereby realizing the delivery or pressurization of the fluid. During the long-term operation of the pump body 21, high temperatures will be generated inside and outside the pump body 21. The heat sink 211 on the outside of the pump body 21 can dissipate the high temperature and achieve the purpose of cooling. As the motor 2 starts and the output shaft rotates, it drives the external driving gear 31 to rotate. The rotation of the driving gear 31 drives the driven gear 331 outside the ring 33 at the upper end of the mounting base 32 to rotate. The fan blades 342 rotate together with the bearing 34 and the outer collar 341 by meshing with multiple teeth 343 on the inner wall of the collar 341. The air generated by the rotation of the fan blades 342 is then blown through the ventilation port 221 of the protective cover 22 to the heat sink 211 on the outside of the pump body 21 to accelerate the cooling efficiency of the heat sink 211. Thus, when the air-cooling assembly 3 is cooling the pump body 21, it can rotate and blow air along with the operation of the pump body 21 to cool the heat sink 211 on the outside of the pump body 21, thereby ensuring that the temperature of the pump body 21 can be effectively reduced, thus ensuring the normal operation and service life of the pump.

[0029] Specifically, such as Figure 2 and Figure 4As shown, the front end of the ring 33 is fixedly connected to the upper and lower sides of the ring 33. The ends of the two cover plates 4 that are far apart from each other are fixedly connected to the heat sink 41. There are multiple heat sinks 41. Each heat sink 41 has a through groove 411 inside. The front end of each through groove 411 is fixedly connected to the protective cover 22 by a connecting pipe 42. The through groove 411 is connected to the inside of the protective cover 22 through the connecting pipe 42. The cover plate 4, the heat sink 41 and the connecting pipe 42 are all made of copper.

[0030] By adopting the above technical solution, when the pump body 21 needs to continuously cool down, the heat outside the pump body 21 is transferred to the cover plate 4 attached to the outside of the pump body 21 through the principle of heat conduction, and then to the multiple heat dissipation plates 41 outside the cover plate 4. Then, the output shaft of the motor 2 rotates, driving the external drive gear 31 to rotate. The rotation of the drive gear 31 drives the driven gear 331 outside the ring 33 to rotate. The rotation of the driven gear 331, through the meshing of the teeth 343, drives the bearing 34 and the external collar 341 to rotate together. Then, the rotating fan blades 342 blow air into the through slot 411, and the heat sink 41 transfers heat to the air inside the through slot 411 through heat conduction. The hot air moves along the inner wall of the connecting pipe 42. Due to the material properties of the connecting pipe 42 and its contact with the outside air, the heat is dispersed to the outside of the connecting pipe 42 to cool the hot air inside the connecting pipe 42. This achieves the purpose of absorbing the heat from the surface of the pump body 21 when cooling the process pump, and performs heat dissipation work. By increasing the surface area, the heat dissipation performance of the device is greatly improved.

[0031] Working principle: When the process pump is working, the motor 2 on the base plate 1 is started to drive the fluid to flow in the pump body 21, thereby realizing the delivery or pressurization of the fluid. During the long-term operation of the pump body 21, high temperatures are generated inside and outside the pump body 21. The heat sink 211 on the outside of the pump body 21 can disperse the high temperature and achieve the purpose of cooling. As the motor 2 starts, the output shaft rotates, which drives the external driving gear 31 to rotate. The rotation of the driving gear 31 drives the driven gear 331 on the outside of the ring 33 to rotate. The rotation of the driven gear 331 then passes through the collar 34. Multiple teeth 343 on the inner wall of the pump body 21 mesh together, causing the bearing 34 to rotate together with the outer collar 341. The air generated by the rotation of the fan blade 342 is then blown through the ventilation port 221 of the protective cover 22 to the heat sink 211 on the outside of the pump body 21 to accelerate the cooling efficiency of the heat sink 211. This allows the air-cooling component 3 to rotate and blow air along with the operation of the pump body 21 when cooling the pump body 21, thereby effectively reducing the temperature of the pump body 21 and ensuring the normal operation and service life of the pump.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
