[0002] Submersible chemical pump is a kind of equipment specially used for conveying liquid without solid particles, and the temperature of the conveyed medium is usually not more than 80℃. This kind of pump is widely used in the fields of industry, pharmacy and laboratory, especially in the occasions where chemical reagents, coolants, engine oil, solvents, etc. need to be injected.

[0003] In the chemical manufacturing industry, there are many working conditions where the material medium temperature exceeds the normal design temperature conditions. Therefore, when a conventional submersible chemical pump is conveying a medium with an excessively high temperature, the material medium will enter the bearing along the pump shaft, which can easily cause the bearing grease to be diluted and lost due to high temperature, resulting in dry friction between the bearing and the pump shaft, which will cause greater wear, and the mechanical properties of the bearing and the pump shaft will gradually decline, greatly reducing the service life. Utility Model Content

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0017] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] The utility model embodiment provides a new structure of a cooling liquid chemical pump, such as Figure 1-3 As shown, the novel structure of the cooling submersible chemical pump comprises: a submersible chemical pump body 1 including a pump shaft 2, a connecting pipe 3, a bearing seat 4 and a base plate 5; a first flange 6 arranged on the bearing seat 4; a second flange 7 arranged on the base plate 5; a steel pipe 8 welded to the side where the first flange 6 and the second flange 7 are close to each other; a partition plate 9 welded to the inner wall of the steel pipe 8, on which a sleeve 10 is fixedly mounted; and a water inlet pipe 11 and a water outlet pipe 12 for cooling the transmitted medium are arranged on the steel pipe 8.

[0019] It should be noted that in the chemical manufacturing industry, there are many working conditions where the material medium temperature exceeds the normal design temperature conditions. Therefore, when a conventional submersible chemical pump is conveying a medium with an excessively high temperature, the material medium will enter the bearing along the pump shaft, which can easily cause the bearing grease to be diluted and lost due to high temperature, resulting in dry friction between the bearing and the pump shaft, which will cause greater wear, and the mechanical properties of the bearing and pump shaft will gradually decline, greatly reducing the service life.

[0020] In the scheme, the submersible chemical pump body 1 includes key components such as a pump shaft 2, a connecting pipe 3, a bearing seat 4 and a bottom plate 5. In order to cool the medium flowing along the pump shaft 2, a first flange 6 is arranged on the bearing seat 4, and a second flange 7 is arranged on the bottom plate 5. The two flanges are welded and connected by a steel pipe 8 to form a cooling water channel surrounding the pump shaft 2. A partition 9 is welded on the inner wall of the steel pipe 8, and a sleeve 10 is fixedly installed on the partition 9. This design allows cooling water to enter the sealed cavity formed by the steel pipe 8, the partition 9 and the sleeve 10 through the water inlet pipe 11, and flow around the pump shaft 2, through thermal exchange. The temperature of the medium flowing along the pump shaft 2 is reduced, and then the cooling water is discharged from the outlet pipe 12 to form a complete cooling cycle. Through this new structure of cooling submersible chemical pump, when the submersible chemical pump body 1 is conveying high-temperature medium, the cooling water can effectively reduce the temperature of the medium and prevent the bearing grease from being lost due to high-temperature dilution. This not only ensures good lubrication between the bearing and the pump shaft 2 and reduces wear, but also improves the working efficiency and stability of the pump and extends its service life. In addition, the new structure of cooling submersible chemical pump also has the advantages of simple structure, easy installation, saving production costs, and shorter production cycle.

[0021] In a further preferred embodiment of the present invention, the sleeve 10 , the steel pipe 8 and the partition plate 9 are all made of stainless steel, and the sleeve 10 is located outside the pump shaft 2 .

[0022] In this embodiment, the sleeve 10, steel pipe 8 and partition 9 are components that are in direct contact with the cooling water and are all made of stainless steel. Stainless steel has excellent corrosion resistance and high temperature resistance, and can maintain structural stability and integrity in a high temperature and high humidity environment for a long time. Therefore, the use of stainless steel can effectively prevent these components from leaking cooling water or reducing the cooling effect due to corrosion or deformation. Secondly, the sleeve 10 is arranged on the outside of the pump shaft 2. This design allows the cooling water to directly surround the pump shaft 2, and take away the heat of the medium flowing along the pump shaft 2 through heat exchange, thereby achieving a better cooling effect.

[0023] In a further preferred embodiment of the utility model, the partition plate 9 is arranged in a ring shape, and a plurality of first bolts are threadedly mounted on the bearing seat 4 , and the plurality of first bolts are all threadedly connected to the first flange 6 .

[0024] In this embodiment, firstly, the partition 9 is designed to be annular. This shape not only enhances the structural strength of the partition 9, enabling it to withstand greater pressure and impact force, but also can better cooperate with the steel pipe 8 and the sleeve 10 to form a stable cooling water channel. At the same time, the annular partition 9 can also effectively isolate the cooling water from other components inside the pump to prevent the cooling water from leaking or mixing with other media. Secondly, a plurality of first bolts are threadedly installed on the bearing seat 4, and these bolts are all threadedly connected to the first flange 6. This installation method not only makes the connection between the first flange 6 and the bearing seat 4 more firm and reliable, but also can be easily disassembled and repaired. At the same time, by reasonably arranging the number and position of the bolts, it can be ensured that the first flange 6 can be evenly stressed when subjected to external force to avoid stress concentration or deformation.

[0025] In a further preferred embodiment of the utility model, a plurality of second bolts are threadedly mounted on the base plate 5 , and the plurality of second bolts are all threadedly connected to the second flange 7 .

[0026] In this embodiment, a plurality of second bolts are threadedly installed on the base plate 5, and these second bolts are all threadedly connected to the second flange 7. This installation method not only enhances the connection strength between the base plate 5 and the second flange 7, making the entire cooling structure more stable, but also facilitates disassembly and maintenance, thereby improving the maintainability of the equipment.

[0027] The working principle of the new structure of the cooling liquid chemical pump provided by the utility model is as follows:

[0028] When the submersible chemical pump body 1 is conveying high-temperature medium, the high-temperature medium will flow upward from the connecting pipe 3 along the pump shaft 2, so that the medium can flow into the gap between the pump shaft 2 and the sleeve 10. With the use of the water inlet pipe 11, cold water can be injected into the sealed cavity formed by the steel pipe 8, the partition plate 9 and the sleeve 10, and flow around the pump shaft 2. In this way, the temperature of the medium flowing along the pump shaft 2 can be reduced by heat exchange. After absorbing the temperature of the medium, the water will be discharged from the water outlet pipe 12. Through this new structure of the cooling submersible chemical pump, when the submersible chemical pump body 1 is conveying high-temperature medium, the cooling water can effectively reduce the temperature of the medium and prevent the bearing grease from being lost due to high-temperature dilution. This not only ensures good lubrication between the bearing and the pump shaft 2 and reduces wear, but also improves the working efficiency and stability of the submersible chemical pump body 1 and extends its service life. In addition, the new structure of the cooling submersible chemical pump also has the advantages of simple structure, easy installation, saving production costs, and shorter production cycle.
