Description

Technical Field

[0001] This application relates to water circulation cooling systems, and more specifically, to water ring vacuum pump circulating liquid cooling systems. Background Technology

[0002] The working principle of a ring vacuum pump relies on changes in the pump chamber volume to achieve air intake, compression, and exhaust. When the impeller rotates clockwise, water is thrown outwards by the impeller. Due to centrifugal force, the water forms a closed ring of approximately uniform thickness, determined by the shape of the pump chamber. The lower inner surface of the water ring is tangent to the impeller hub, and the upper inner surface of the water ring is in contact with the tips of the blades (in reality, the blades have a certain insertion depth within the water ring). At this point, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is further divided by the impeller into several small chambers equal to the number of blades. If we take the lower 0° of the impeller as the starting point, then during the first 180° of impeller rotation, the volume of the small chambers increases, and they connect with the intake port on the end face, allowing gas to be drawn in. When the intake is complete, the small chambers are isolated from the intake port. As the impeller continues to rotate, the small chambers decrease in size, compressing the gas. When the small chambers connect with the exhaust port, the gas is discharged from the pump.

[0003] During the production process, the moving parts inside the vacuum pump generate heat due to friction, and the gas also generates heat during compression. This heat is not dissipated. Traditional technology uses drinking water as a medium, supplying water from a tank to the vacuum pump to cool it. The water then returns to the tank, creating a circulation of drinking water between the pump and the tank.

[0004] Water enters the vacuum pump from the water tank and then returns to the water tank from the vacuum pump. During this process, the water absorbs the temperature of the vacuum pump and becomes warmer, thus raising the water temperature in the tank. If the water temperature in the tank exceeds 30°C, new drinking water is added to the tank to cool it down.

[0005] However, during the use of the vacuum unit, the continuous heating will cause the water tank to be constantly replenished with new drinking water. If the water level in the tank is high, some drinking water will need to be discharged, resulting in a large waste of water resources. Therefore, this practice of continuously adding water to the tank to lower the water temperature is uneconomical. Utility Model Content

[0006] The purpose of this application is to provide a circulating liquid cooling system for a water ring vacuum pump, which can reduce resource waste.

[0007] To achieve the above objectives, this utility model provides a water ring vacuum pump circulating liquid cooling system, comprising:

[0008] A cooling medium storage container, wherein the cooling medium storage container is used to store the cooling medium and circulate the cooling medium to the water ring vacuum pump;

[0009] A temperature acquisition component, wherein the temperature acquisition component is used to acquire the temperature of the cooling medium in the cooling medium storage container;

[0010] A cooling component, when the temperature of the cooling medium obtained by the temperature acquisition component exceeds the warning temperature, cools the cooling medium in the cooling medium storage container. The cooling component includes a low-temperature medium source and a cooling pipe. The cooling pipe is disposed in the cooling medium storage container and is in contact with the cooling medium in the cooling medium storage container. The low-temperature medium source is connected to the cooling pipe and circulates a fluid medium with a temperature lower than that of the cooling medium in the cooling medium storage container to the cooling pipe.

[0011] In an optional embodiment, the cooling assembly further includes a temperature control valve disposed between the cooling pipe and the cryogenic medium source;

[0012] When the temperature control valve is open, the low-temperature medium source supplies fluid medium to the cooling pipe;

[0013] The temperature control valve is electrically connected to the temperature acquisition component. When the temperature of the cooling medium acquired by the temperature acquisition component exceeds the warning temperature, the temperature control valve opens.

[0014] In an optional embodiment, a cooling medium source is further included, which is connected to the cooling medium storage container and is used to supply cooling medium to the cooling medium storage container.

[0015] In an optional embodiment, the cooling medium storage container is provided with an over-standard level discharge port.

[0017] In an optional embodiment, the cooling medium storage container is provided with a cooling medium outlet connected to the liquid inlet of the water ring vacuum pump and a cooling medium return port connected to the liquid outlet of the water ring vacuum pump.

[0020] In an optional embodiment, the cooling pipe is an S-shaped pipe.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] Embodiments of this application provide a water ring vacuum pump circulating liquid cooling system, such as... Figure 1 As shown, the system includes a cooling medium storage container 100, a temperature acquisition component 200, and a cooling component.

[0038] For example, the cooling medium storage container 100 includes, but is not limited to, storage tanks, storage bags, storage cylinders, or storage boxes.

[0039] During use, the cooling medium storage container 100 stores the cooling medium.

[0040] The cooling medium storage container 100 is used to store the cooling medium and circulate it to the water ring vacuum pump 500. During use, the cooling medium in the cooling medium storage container 100 is transported to the water ring vacuum pump 500, where it exchanges heat with the pump, causing the cooling medium to heat up. The cooling medium in the water ring vacuum pump 500 then flows back to the cooling medium storage container 100, thus achieving the effect of circulating the cooling medium to the water ring vacuum pump 500.

[0041] For example, the cooling medium in the cooling medium storage container 100 is delivered to the water ring vacuum pump 500 by a liquid pump.

[0042] For example, the cooling medium may be water, heat transfer oil (an oil-based medium with good thermal conductivity, such as mineral-based heat transfer oil, alkyl biphenyl-based heat transfer oil, etc.), ethylene glycol, propylene glycol, or a water-ethanol mixture.

[0043] The temperature acquisition component 200 is used to acquire the temperature of the cooling medium in the cooling medium storage container 100.

[0044] For example, the temperature acquisition component 200 is disposed in the cooling medium storage container 100 and in contact with the cooling medium to acquire the temperature of the cooling medium. The temperature acquisition component 200 is at least one of the following: a bimetallic thermometer, a glass liquid thermometer, a pressure thermometer, a resistance thermometer, a thermistor, or a thermocouple, etc. However, in another embodiment, the temperature acquisition component 200 is located outside the cooling medium and performs temperature measurement in a non-contact manner; the temperature acquisition component 200 is an infrared temperature sensor.

[0045] If the temperature of the cooling medium obtained by the temperature acquisition component 200 exceeds the warning temperature, the cooling component cools the cooling medium in the cooling medium storage container 100.

[0046] For example, the warning temperature can be set according to the actual needs of the project, such as a warning temperature of 28℃-45℃; for example, a warning temperature of 28℃; for example, a warning temperature of 30℃; for example, a warning temperature of 35℃; for example, a warning temperature of 40℃; for example, a warning temperature of 45℃.

[0047] The cooling assembly includes a cryogenic medium source 300 and a cooling pipe 310. The cooling pipe 310 is disposed in the cooling medium storage container 100 and is in contact with the cooling medium in the cooling medium storage container 100, so that the cooling pipe 310 can cool the cooling medium in the storage container.

[0048] The cryogenic medium source 300 is connected to the cooling pipe 310 and circulates a fluid medium to the cooling pipe 310. The cryogenic medium source 300 provides a cryogenic fluid medium, the temperature of which is lower than the temperature of the cooling medium in the cooling medium storage container 100. The fluid medium exchanges heat with the cooling medium in the cooling medium storage container 100 in the cooling pipe 310, thereby reducing the temperature of the cooling medium.

[0049] Fluid media include, for example, water, heat transfer oil (oil-based media with good thermal conductivity, such as mineral-based heat transfer oil, alkyl biphenyl-based heat transfer oil, etc.), ethylene glycol, propylene glycol, air, and refrigerants. Refrigerants include, for example, Freon.

[0050] In one embodiment, the cryogenic medium source 300 includes a fan and a cryogenic medium storage container. The fluid medium is, for example, water, ethylene glycol, or propylene glycol. The cryogenic medium storage container stores the fluid medium. The fan is located at the cryogenic medium storage container and rotates to accelerate the evaporation and cooling of the cryogenic medium. The cryogenic medium storage container is connected to a cooling pipe 310 and supplies the cryogenic medium to the cooling pipe 310. Exemplarily, the cryogenic medium storage container includes, but is not limited to, a storage tank, a storage bag, a storage cylinder, or a storage box. In other embodiments, the cryogenic medium source 300 includes a cryogenic medium storage container and a cooler. The cryogenic medium storage container stores the fluid medium and is connected to the cooling pipe 310, supplying the cryogenic medium to the cooling pipe 310. The cooler is used to cool the fluid medium in the cryogenic medium storage container. The cooler compresses the refrigerant into a liquid. While the refrigerant is being converted into a gas, it absorbs the heat of the fluid medium, thereby cooling the fluid medium and making its temperature lower than the temperature of the cooling medium in the cooling medium storage container 100. Exemplarily, the cryogenic medium storage container includes, but is not limited to, a storage tank, a storage bag, a storage cylinder, or a storage box. In other embodiments, the cryogenic medium source 300 is chilled water supplied to the radiant air conditioning equipment, the temperature of which is lower than the temperature of the cooling medium in the cooling medium storage container 100.

[0051] Compared to related technologies that involve continuously adding low-temperature water to a water tank, resulting in excessive cooling water discharge and significant water waste, this application uses the fluid medium in the cooling pipe 310 to cool the cooling medium in the cooling medium storage container 100. This allows the cooling medium in the storage container 100 to be maintained at a relatively constant liquid level, reducing waste. Furthermore, the fluid medium can be recycled, further reducing resource consumption and aligning with the concept of sustainable development, resulting in significant economic and environmental benefits.

[0052] like Figure 1As shown, in one embodiment, the cooling assembly further includes a temperature control valve 320 disposed between the cooling pipe 310 and the cryogenic medium source 300.

[0053] For example, the cooling pipe 310 is connected to the cryogenic medium source 300 via a discharge pipe and a return pipe. The fluid medium enters the cooling pipe 310 through the discharge pipe, and the fluid medium in the cooling pipe 310 returns to the cryogenic medium source 300 through the return pipe. A temperature control valve 320 is installed on the discharge pipe to control the opening or closing of the discharge pipe. A suction pump is installed on the discharge pipe to deliver the fluid medium to the cooling pipe 310.

[0054] With the temperature control valve 320 open, the low-temperature medium source 300 supplies fluid medium to the cooling pipe 310 through the discharge pipe.

[0055] The temperature control valve 320 is electrically connected to the temperature acquisition component 200. When the temperature of the cooling medium acquired by the temperature acquisition component 200 exceeds the warning temperature, the temperature control valve 320 opens.

[0056] For example, such as Figure 2 As shown, the temperature acquisition component 200 includes a temperature probe 210 disposed in the cooling medium storage container 100 and in contact with the cooling medium, and a temperature controller 220 electrically connected to the temperature probe 210. The temperature controller 220 is also electrically connected to a temperature control valve 320. During use, the temperature probe 210 detects the temperature of the cooling medium and sends the detection result to the temperature controller 220. If the temperature of the cooling medium is higher than the warning temperature, the temperature controller 220 controls the temperature control valve 320 to open, and the fluid medium is transported from the low-temperature medium source 300 to the cooling pipe 310 to cool the cooling medium. This automatic adjustment mechanism effectively avoids the impact of excessively high or low cooling medium temperatures on the performance of the water ring vacuum pump 500, ensures the stable operation of the water ring vacuum pump 500, and extends the service life of the equipment.

[0057] The temperature control valve 320 controls the supply of fluid medium from the cryogenic medium source 300 to the cooling pipe 310, ensuring stable circulation of the fluid medium in the cooling pipe 310. When the cooling medium temperature is normal, the temperature control valve 320 is closed to reduce unnecessary fluid medium flow and lower system energy consumption; when the temperature is abnormal, the temperature control valve 320 is opened to promptly replenish the cryogenic fluid medium for cooling, maintaining the dynamic balance of the entire cooling system and improving the system's stability and reliability.

[0058] like Figure 1 As shown, in one embodiment, the water ring vacuum pump circulating liquid cooling system further includes a cooling medium source 400, which is connected to a cooling medium storage container 100 and is used to supply cooling medium to the cooling medium storage container 100.

[0059] For example, the cooling medium source 400 is a tap water pipe, water tank, etc.

[0060] For example, the cooling medium source 400 can provide a pressurized cooling medium to the cooling medium storage container 100, the pressure of which enables the cooling medium to move from the cooling medium source 400 to the cooling medium storage container 100. However, in another embodiment, a pump is provided between the cooling medium source 400 and the cooling medium storage container 100 for driving the cooling medium from the cooling medium source 400 to the cooling medium storage container 100.

[0061] By setting up a cooling medium source 400, cooling medium can be replenished to the cooling medium storage container 100.

[0062] For example, a valve body is also provided between the cooling medium source 400 and the cooling medium storage container 100, which is used to control the connection or disconnection of the cooling medium source 400 and the cooling medium storage container 100.

[0063] like Figure 1 As shown, in one embodiment, the cooling medium storage container 100 is provided with an over-standard level discharge port 110. When the cooling medium liquid level in the cooling medium storage container 100 exceeds a preset liquid level, the cooling medium exceeding the preset liquid level is discharged from the cooling medium storage container 100 through the over-standard level discharge port 110.

[0064] For example, a one-way valve is also provided at the over-standard level outlet 110. Cooling medium exceeding the preset liquid level is discharged from the over-standard level outlet 110 and the one-way valve into the cooling medium storage container 100. The one-way valve prevents external fluid from entering the cooling medium storage container 100 from the over-standard level outlet 110.

[0065] like Figure 1 As shown, in one embodiment, a cleaning outlet 120 is provided at the bottom of the cooling medium storage container 100. When the cooling medium storage container 100 needs to be cleaned of dirt, the dirt can be discharged from the cleaning outlet 120.

[0066] like Figure 1 As shown, in one embodiment, the cooling medium storage container 100 is provided with a cooling medium outlet 130 connected to the liquid inlet of the water ring vacuum pump 500 and a cooling medium return port 140 connected to the liquid outlet of the water ring vacuum pump 500.

[0067] For example, the height of the cooling medium outlet 130 on the cooling medium storage container 100 is less than the height of the cooling medium return port 140 on the cooling medium storage container 100.

[0068] For example, during use, the cooling medium enters the water ring vacuum pump 500 from the cooling medium outlet 130 on the cooling medium storage container 100, the cooling medium exchanges heat with the water ring vacuum pump 500, and the cooling medium in the water ring vacuum pump 500 is discharged from the liquid outlet of the water ring vacuum pump 500 and flows back to the cooling medium storage container 100 from the cooling medium return port 140.

[0069] like Figure 3 As shown, in one embodiment, the cooling medium outlet 130 and the cooling medium return port 140 are connected to a pipe network 150, which is connected to at least two water ring vacuum pumps 500, so that the cooling medium storage container 100 circulates cooling medium to at least two water ring vacuum pumps 500 through the pipe network 150.

[0070] Because the cost of the cryogenic medium source 300 is relatively high, the equipment cost of configuring one cryogenic medium source 300 for each water ring vacuum pump 500 is high. Therefore, the pipeline network 150 is set up so that at least two water ring vacuum pumps 500 can share the same cryogenic medium source 300, which can reduce the equipment cost.

[0071] For example, two water ring vacuum pumps 500 are connected to the pipe network 150. In other embodiments, such as Figure 3 As shown, three water ring vacuum pumps 500 are connected to the pipe network 150. Of course, other numbers of water ring vacuum pumps 500, such as four, five, or six, can also be connected to the pipe network 150.

[0072] For example, a check valve is provided on the pipeline 150 located at the liquid outlet of the water ring vacuum pump 500 to prevent the cooling medium from entering the water ring vacuum pump 500 from the liquid outlet.

[0073] In one embodiment, the cooling pipe 310 is a spiral coil to increase the contact area between the cooling pipe 310 and the cooling medium, thereby improving the heat exchange efficiency.

[0074] Unlike the above embodiment where the cooling pipe 310 is a spiral coil, as shown in the example... Figure 1 and Figure 3 As shown, in another embodiment, the cooling pipe 310 is an S-shaped pipe. This embodiment can also increase the contact area between the cooling pipe 310 and the cooling medium, thereby improving the heat exchange efficiency.

[0075] like Figure 1 and Figure 3 As shown, in one embodiment, the water ring vacuum pump circulating liquid cooling system further includes a drain pipe 510 disposed on the water ring vacuum pump 500, the drain pipe 510 being used for draining the water ring vacuum pump 500.

[0076] For example, when the water ring vacuum pump 500 is not used for a long time, it will generate dirt, which can be discharged through the drain pipe 510.

[0077] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
