Description

Technical Field

[0001] This utility model relates to the field of energy-saving and high-temperature resistant centrifugal pump manufacturing technology, and in particular to a radially split energy-saving and high-temperature resistant centrifugal pump. Background Technology

[0002] Currently, the most commonly used high-temperature resistance methods for radially split high-temperature centrifugal pumps in the industry are mainly three types: The first method uses water cooling, introducing external cooling circulating water into the water-cooled chambers of the pump body, pump cover, and support legs through external pipes. The water flows directly into the high-temperature components and is then discharged, or a spray device is installed on the surface of the pump body to absorb heat through evaporation of the sprayed cooling water. Although this method can directly contact the heat source to achieve direct cooling, the complex structure of the parts requires the water-cooled chambers to be machined in the pump body and pump cover, resulting in high manufacturing costs. It is also dependent on water resources and cannot be used in water-scarce environments. Poor water quality can also cause scaling and pipe blockage, leading to high maintenance costs. In winter, antifreeze measures are also required to prevent the pipes from freezing and cracking. The cooling water needs to be used in conjunction with auxiliary equipment such as circulating water pumps and cooling tower fans, which consume a lot of energy. Compared with the structure of this patent, it is not very suitable for water-scarce environments and does not achieve the effect of saving water resources and reducing energy consumption. The second method uses air cooling, achieving cooling through heat exchange between the pump body, pump cover, and support surface and the environment. Although this method does not consume water or electricity, it relies on heat sinks or large surface area designs, which limits the component structure and heat dissipation capacity. It is not suitable for high-temperature conditions, and the heat dissipation effect decreases significantly in extreme environments. Compared with the structure of this patent, it is not very suitable for high-temperature conditions and extreme environments. The third method uses fan cooling, which involves installing heat sinks on the pump body, pump cover, and support feet to increase the contact area with air and utilize the airflow generated by the fan to dissipate heat from the parts. While this method can enhance heat dissipation, it requires additional design of air ducts and fan installation locations, taking up equipment space. Moreover, its heat dissipation effect is significantly reduced in environments with high humidity, dust, and poor ventilation, limiting its use for high-temperature centrifugal pumps that require continuous high-load operation. Compared with the structure of this patent, it is less suitable for complex working conditions and environments.

[0003] In view of the problems existing in the above-mentioned existing technologies, it is necessary to study and design a radially split energy-saving high-temperature resistant centrifugal pump to overcome the problems existing in the existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a radially split energy-saving high-temperature centrifugal pump that avoids the problems of complex parts processing, water resource dependence, high-temperature operating conditions, extreme environments, and high maintenance costs associated with circulating water cooling, air cooling, and fan cooling.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a radially split energy-saving high-temperature resistant centrifugal pump, comprising: The pump body has a pump cover mounted on it and a support foot fixedly connected to it. The support foot is fixedly connected to a base. Several heat-conducting copper plates are fixedly connected to the pump body, the pump cover, and the support foot. Flexible heat-conducting buffer pads are fixedly connected to the heat-conducting copper plates. A Peltier module is fixedly connected to the flexible heat-conducting buffer pads. Protective covers are fixedly connected to the pump body, the pump cover, and the support foot. The Peltier module is located inside the protective cover.

[0006] The present invention discloses the following technical effects: 1. This technology is a radially split energy-saving high-temperature centrifugal pump. Compared with the use of circulating water cooling, it does not require the design and processing of water cooling cavities in the pump body, pump cover, and support legs. It does not rely on water resources and does not require auxiliary equipment such as circulating water pumps and cooling tower fans. This reduces the later maintenance costs, reduces the design and processing costs, saves water resources, and has higher applicability while saving energy. 2. This technology is a radially split energy-saving high-temperature centrifugal pump. Compared with air cooling, it does not rely on heat sinks or large surface area design, and does not limit the design of component structure. It can be used stably under high-temperature conditions by increasing the number of Peltier modules. 3. This technology is a radially split energy-saving high-temperature centrifugal pump. Compared with fan cooling, it does not require heat sinks on the pump body, pump cover, and support surface to increase the heat dissipation area. It does not require additional air duct design or fan installation location considerations, and does not occupy equipment space. It is more suitable for compact, high-humidity, dusty, and poorly ventilated environments.

[0007] This invention solves the problems of complex structural design, high processing cost, difficult maintenance, dependence on water resources, high energy consumption, limited environmental space, and poor applicability of centrifugal pumps in complex working conditions in the prior art.

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.

[0011] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] Reference Figure 1 , Figure 2 , Figure 3 This utility model provides a radially split energy-saving high-temperature resistant centrifugal pump, comprising: Pump body 1, pump cover 3 installed on pump body 1, support leg 7 fixedly connected to pump body 1, support leg 7 fixedly connected to base 8, several heat-conducting copper plates 6 fixedly connected to pump body 1, pump cover 3 and support leg 7, flexible heat-conducting buffer pad 5 fixedly connected to heat-conducting copper plate 6, Peltier module 4 fixedly connected to flexible heat-conducting buffer pad 5, protective cover 2 fixedly connected to pump body 1, pump cover 3 and support leg 7, Peltier module 4 located inside protective cover 2.

[0013] A thermally conductive copper plate 6 is installed on the pump body 1, pump cover 3, and support foot 7. To prevent damage to the thermally conductive copper plate 6, it must have a ceramic coating. Multiple Peltier modules 4 are connected in series and parallel. The Peltier modules 4 need to be evenly distributed on the pump body 1, pump cover 3, and support foot 7. The number of Peltier modules 4 depends on the specific working conditions. The high-temperature point of the pump body 1 needs to be connected in series with Peltier modules 4 to gradually reduce the hot end temperature and expand the temperature range. The Peltier modules 4 are fixed with high-temperature resistant epoxy glue. At the same time, a flexible thermally conductive buffer pad 5 is used to buffer the vibration and impact on the Peltier modules 4 generated during pump operation. The circuit of the Peltier module 4 is sealed with IP68 level. To prevent corrosion from environmental media under complex operating conditions, a protective cover 2 needs to be installed on the outside of the Peltier module 4. The protective cover 2 is made of titanium alloy or Hastelloy. The Peltier module 4 is equipped with contact points of two different conductors and is powered by a solar battery. When current passes through the contact points of the two conductors, the current flows from the contact points of the low-energy material to the contact points of the high-energy material. The Peltier module 4 begins to continuously absorb heat, thereby cooling the high-temperature parts. At the same time, a temperature sensor, such as a PT100, is installed on the pump body. The PT100 can be connected to a local control cabinet with display function or transmitted to a distributed control system to detect the temperature in real time.

[0014] Figure 1 and Figure 3 The energy storage battery and temperature sensing element are not shown in the diagram; their specific locations will depend on the site conditions. Figure 1 The protective cover 2 is for illustration only and should be arranged according to the actual situation based on the number of Peltier modules 4.
