Description

Technical Field

[0001] The invention relates to the field of temperature control, and in particular to a vacuum isothermal forging high-efficiency circulating cooling system and a control method and a storage medium. Background Art

[0002] Vacuum isothermal forging is a precision forging technology that requires a constant temperature to be maintained throughout the forging process to ensure uniformity of the material's internal structure and properties. Closed-loop cooling water can provide a stable and controllable cooling capacity to meet the temperature requirements of isothermal forging.

[0003] The prior art, such as the invention patent with announcement number: CN102402233B, is a transformer cooling system automatic control device, including an air switch ZK, a relay BC1 contact BC1-1, a submersible oil pump thermal protection relay BRJ, and a cooler fan thermal protection relay FRJ. It is characterized in that a relay contact BC2-1 for controlling the operation of the cooler fan is connected between the cooler fan thermal protection relay FRJ and the relay contact BC1-1, and the relay BC2 is connected to the relay BC2 power supply control circuit composed of a temperature control switch.

[0004] Prior art, such as the invention patent with announcement number: CN118732728B, is a radiator temperature monitoring method, device, equipment and storage medium, wherein the method includes: obtaining environmental parameter ranges corresponding to multiple working environments of the current device and fan operation information; determining a fan speed adjustment strategy based on the fan operation information, adjusting the speed of each fan in the current device according to the fan speed adjustment strategy under each set of environmental parameters corresponding to each working environment, and obtaining the temperature of each radiator to obtain the radiator temperature under each set of environmental parameters corresponding to each working environment; constructing a target temperature protection curve for each radiator based on the radiator temperature under each set of environmental parameters corresponding to each working environment, and monitoring the temperature of each radiator based on the target temperature protection curve, the real-time temperature of each radiator and the current environmental parameters of the device.

[0005] Based on the above scheme, it can be seen that the existing technology in the field of automatic temperature control often relies on fixed-configuration thermal protection relays, which may not be able to adapt to different changes in cooling requirements. In actual applications, the cooling requirements may gradually change as the cooling progresses. Due to the combined influence of multiple factors, the temperature changes are often more complex and difficult to predict. When performing temperature control, only configuring fixed hardware parameters may cause deviations in the temperature control results, resulting in unsatisfactory temperature control effects. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a vacuum isothermal forging efficient circulating cooling system and control method, and a storage medium. To achieve the above purpose, the present invention is implemented through the following technical solutions: a vacuum isothermal forging efficient circulating cooling system and control method, and a storage medium, including: The initial self-test module is used to detect the patency of the cooling water pipeline at the initial moment of starting vacuum isothermal forging, and obtain the patency test result of the cooling water pipeline. If the patency test result of the cooling water pipeline is unqualified, an early warning is sent to the management terminal. If the patency test result of the cooling water pipeline is qualified, an automatic forging start signal is generated to the switch controller for vacuum isothermal forging start control.

[0007] The sensor monitoring module is used to obtain the real-time temperature of the forging chamber and send it to the data processing module, and at the same time monitor the real-time water flow parameters in the cooling water pipeline and send them to the data processing module.

[0008] The external environment monitoring module is used to obtain the external environment parameters of the cooling water pipeline, obtain the external environment impact correction factor through comprehensive analysis and processing, and send it to the data processing module.

[0009] The data processing module is used to obtain the cooling water flow required for the forging chamber based on the real-time temperature analysis of the forging chamber, and to obtain the transmission loss influence factor of the cooling water pipeline based on the real-time water flow parameters of the cooling water pipeline and the external environmental influencing factors. The cooling water flow required for the forging chamber and the transmission loss influence factor of the cooling water pipeline are comprehensively analyzed to obtain the total cooling water flow required for the forging chamber.

After the sound wave receiver installed at the water outlet of the cooling water pipe receives the pure tone sinusoidal sound wave signal, the transmission signal parameters of the pure tone sinusoidal sound wave are obtained, including the speed, frequency, maximum amplitude and waveform function of the pure tone sinusoidal sound wave signal. Based on the transmission signal parameters of the pure tone sinusoidal sound wave, the patency evaluation value of the cooling water pipe is analyzed and processed, and the patency evaluation value of the cooling water pipe is used to evaluate whether there is blockage in the cooling water pipe.

[0012] As a preferred technical solution, the cooling water pipeline patency detection result is obtained, specifically including: If the patency assessment value of the cooling water pipeline is less than or equal to the patency assessment threshold, the patency test result of the cooling water pipeline is determined to be unqualified, and an early warning is sent to the management terminal.

[0013] If the patency assessment value of the cooling water pipeline is greater than the patency assessment threshold, the patency detection result of the cooling water pipeline is determined to be qualified, and an automatic forging start signal is generated to the switch controller for vacuum isothermal forging start control.

[0016] As a preferred technical solution, the cooling water flow required for the forging chamber is obtained based on the real-time temperature analysis of the forging chamber, specifically including: Based on the real-time temperature of the forging chamber, it is compared with the set cooling temperature. If the real-time temperature of the forging chamber is less than or equal to the set cooling temperature, a minimum speed signal is sent to the closed-loop pumping unit to make the closed-loop pumping unit run at the minimum speed, so as to achieve the purpose of reducing the cooling water flow rate. The real-time temperature of the forging chamber is subtracted from the set cooling temperature to obtain the required heating temperature difference. The required heating temperature difference is mapped and matched with the heater power adjustment values ​​corresponding to each required heating temperature difference interval pre-stored in the database to obtain the power adjustment value of the heater in the forging chamber and execute control.

[0017] If the real-time temperature of the forging chamber is greater than the set cooling temperature, a differential process is performed to obtain the cooling temperature difference, and the cooling temperature difference is mapped and matched with the cooling water flow corresponding to each cooling temperature difference interval pre-stored in the database to obtain the required cooling water flow of the forging chamber.

[0018] As a preferred technical solution, the transmission loss influencing factor of the cooling water pipeline is obtained based on the real-time water flow parameters of the cooling water pipeline and the external environmental influencing factor, specifically including: The real-time water flow parameters of the cooling water pipeline are processed to obtain the real-time water flow characteristic value of the cooling water pipeline, and the transmission influence characteristic value of the cooling water pipeline is obtained by analyzing and processing in combination with the patency assessment value of the cooling water pipeline and the external environmental influencing factors.

[0019] As a preferred technical solution, the total cooling water flow required by the forging chamber is obtained by comprehensively analyzing the cooling water flow required by the forging chamber and the transmission loss influencing factor of the cooling water pipeline, specifically including: Based on the transmission loss influencing factor of the cooling water pipeline, the cooling water supplementary flow corresponding to each transmission loss influencing factor interval preset in the database is mapped and matched to obtain the cooling water supplementary flow of the cooling water pipeline, and then added to the cooling water flow required by the forging chamber to obtain the total cooling water flow required by the forging chamber.

[0020] As a preferred technical solution, the processing obtains the real-time water flow characteristic value of the cooling water pipeline, and the specific processing conditions are: ; in, is the real-time water flow characteristic value of the cooling water pipeline, For cooling water pipe Real-time water temperature at each point, For cooling water pipe Real-time flow rate at each point, For cooling water pipe Real-time water pressure at each point, For cooling water pipe The expected water temperature at each point, For cooling water pipe The expected flow rate at each point, For cooling water pipe The expected water pressure at each point, is the water temperature weight factor, is the flow velocity weight factor, is the water pressure weight factor, Number the cooling water pipeline points. , is the total number of cooling water pipeline points.

At the initial moment of starting vacuum isothermal forging, the cooling water pipeline is tested for patency to obtain the cooling water pipeline patency test result. If the cooling water pipeline patency test result is unqualified, an early warning is sent to the management terminal.

[0027] Compared with the prior art, the embodiments of the present invention have at least the following beneficial effects: (1) The present invention provides a vacuum isothermal forging high-efficiency circulating cooling water system, which analyzes the patency of the cooling water pipeline by sending a pure tone sinusoidal sound wave signal with preset parameters to the cooling water pipeline, and obtaining the transmission signal parameters of the pure tone sinusoidal sound wave after receiving it. This method does not require shutdown inspection and will not interfere with the normal operation of the cooling system.

It can quickly respond to changes in the forging process to ensure that the cooling water flow always meets the demand, optimize the production process, avoid the pumping unit running at a high speed for a long time, reduce equipment wear, and reduce maintenance costs.

[0030] Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 It is a schematic diagram of the system module of the present invention.

[0032] Figure 2 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0035] See also Figure 1 As shown, an embodiment of the present invention provides a vacuum isothermal forging high-efficiency circulating cooling water system, comprising: The initial self-test module is used to detect the patency of the cooling water pipeline at the initial moment of starting vacuum isothermal forging, and obtain the patency test result of the cooling water pipeline. If the patency test result of the cooling water pipeline is unqualified, an early warning is sent to the management terminal. If the patency test result of the cooling water pipeline is qualified, an automatic forging start signal is generated to the switch controller for vacuum isothermal forging start control.

[0036] The specific process of testing the patency of the cooling water pipeline is as follows: Based on the sound wave transmitter installed at the water inlet of the cooling water pipe, a pure tone sinusoidal sound wave signal with a preset frequency and amplitude is sent to the cooling water pipe. After the sound wave receiver installed at the water outlet of the cooling water pipe receives the pure tone sinusoidal sound wave signal, the transmission signal parameters of the pure tone sinusoidal sound wave are obtained, including the speed, frequency, maximum amplitude and waveform function of the pure tone sinusoidal sound wave signal. Based on the transmission signal parameters of the pure tone sinusoidal sound wave, the patency evaluation value of the cooling water pipe is analyzed and processed, and the patency evaluation value of the cooling water pipe is used to evaluate whether there is blockage in the cooling water pipe.

[0037] It should be explained that the speed, frequency, maximum amplitude and waveform function of the pure tone sinusoidal sound wave signal have the following effects when evaluating the patency of the cooling water pipeline: In pipeline patency testing, the speed of sound waves can help determine the properties (such as gas, liquid or solid) and state (such as temperature, pressure) of the medium in the pipeline. Sound waves propagate at different speeds in different media, and by measuring the changes in the speed of sound waves, it can be inferred whether there is a blockage in the pipeline.

[0038] The choice of frequency is critical for pipeline inspection. Sound waves of different frequencies are sensitive to different types and sizes of defects in the pipeline. For example, low-frequency sound waves can penetrate thicker materials or bypass larger obstacles, while high-frequency sound waves are more easily reflected by small defects. By analyzing the frequency changes of the reflected sound waves, obstacles or defects in the pipeline can be identified.

[0039] In pipeline inspection, the maximum amplitude of the sound wave is related to the propagation distance and energy loss of the sound wave. When the sound wave encounters an obstacle in the pipeline, part of the sound energy will be reflected back. The degree of amplitude attenuation can be used to evaluate the patency of the pipeline.

[0040] Waveform function analysis can provide detailed information about the sound waves as they propagate through the pipeline. Ideally, the emitted sound waves are sinusoidal waveform functions, but when the sound waves encounter defects in the pipeline, the reflected waveform function may be deformed. By comparing the emitted waveform function with the received waveform function, the type and location of defects in the pipeline can be identified.

[0041] It should be noted that, in the embodiment of the present invention, the phase angle of the transmitted pure tone sinusoidal sound wave signal is 0, and the sound wave period is 1.

[0042] The analysis and processing to obtain the cooling water pipeline patency evaluation value specifically includes: ; ; ; ; in, is the evaluation value of the cooling water pipeline patency, is the speed of the pure tone sinusoidal sound wave signal, is the frequency of the pure tone sinusoidal sound wave signal, is the maximum amplitude of a pure tone sinusoidal sound wave signal, is the waveform function of the pure tone sinusoidal sound wave signal, It is the preset speed when sending pure tone sinusoidal sound wave signal. It is the preset frequency when sending pure tone sinusoidal sound wave signal. It is the preset amplitude when the pure tone sinusoidal sound wave signal is sent. is the preset waveform function when sending pure tone sinusoidal sound wave signal, t is the time, and softplus function is a built-in function in Python. .

[0043] It should be noted that there is a certain correlation between the speed, frequency, maximum amplitude and waveform function of pure tone sinusoidal sound wave signals. The frequency determines the periodicity of the sound wave, that is, the number of times the waveform function is repeated per unit time. The higher the frequency, the shorter the period of the sound wave, and the more times the waveform function is repeated per unit time. The waveform function is determined by the frequency and amplitude of the sound wave, so the change in frequency will directly affect the shape of the waveform function. The maximum amplitude determines the intensity or energy of the sound wave. In the waveform function diagram, the amplitude is expressed as the height of the peak and the trough. The larger the amplitude, the stronger the energy of the sound wave, and the larger the fluctuation range of the waveform function on the vertical axis. The speed of the sound wave affects the time it takes for the sound wave to propagate in the medium, but does not directly affect the shape of the waveform function. However, if the sound wave encounters different media or obstacles during propagation, the change in speed may cause distortion of the waveform function, such as reflection, refraction or attenuation. The frequency is inversely proportional to the wavelength, and the speed is the product of the frequency and the wavelength.

[0044] The obtaining of the cooling water pipeline patency test result specifically includes: If the patency assessment value of the cooling water pipeline is less than or equal to the patency assessment threshold, the patency test result of the cooling water pipeline is determined to be unqualified, and an early warning is sent to the management terminal.

[0045] If the patency assessment value of the cooling water pipeline is greater than the patency assessment threshold, the patency detection result of the cooling water pipeline is determined to be qualified, and an automatic forging start signal is generated to the switch controller for vacuum isothermal forging start control.

[0046] The patency assessment threshold is processed as follows: In a specific embodiment, the patency assessment threshold is set directly in the database during the development of the vacuum isothermal forging high-efficiency circulating cooling water system involved in the embodiment of the present invention. There are many methods for setting the patency assessment threshold, such as obtaining it through statistical analysis, including counting the patency assessment values ​​under historical high patency states, and averaging the patency assessment values ​​obtained multiple times to obtain the patency assessment threshold, or experts judge the boundary between high patency assessment values ​​and low patency assessment values ​​through corresponding historical data to set the threshold, thereby adjusting the threshold.

[0047] The sensor monitoring module is used to obtain the real-time temperature of the forging chamber and send it to the data processing module, and at the same time monitor the real-time water flow parameters in the cooling water pipeline and send them to the data processing module.

[0048] The monitoring of the real-time water flow parameters in the cooling water pipeline specifically includes: A number of integrated sensors distributed at equal distances in the cooling water pipeline are recorded as point-position integrated sensors.

[0049] The real-time water flow parameters in the cooling water pipeline are monitored by integrated sensors at various points, and the real-time water flow parameters in the cooling water pipeline include the real-time water temperature at each point, the real-time flow velocity at each point, and the real-time water pressure at each point.

[0050] The real-time water temperature at each point refers to the water temperature at each point in the cooling water pipeline. Water temperature is a key indicator for measuring cooling efficiency. If the water temperature is too high, it may indicate insufficient cooling capacity, causing equipment overheating. If the water temperature is too low, it may indicate excessive cooling, affecting energy efficiency.

[0051] The real-time flow rate at each point refers to the speed at which the cooling water flows at each point in the pipeline. The flow rate directly affects the heat exchange efficiency of the cooling water. Too fast a flow rate may cause pipeline wear, while too slow a flow rate may lead to insufficient cooling.

[0052] The real-time water pressure at each point refers to the pressure of cooling water at each point in the pipeline. Water pressure is the driving force to ensure the flow of cooling water. Insufficient water pressure may cause slow water flow and affect the cooling effect. Excessive water pressure may cause damage to the pipeline.

[0053] The external environment monitoring module is used to obtain the external environment parameters of the cooling water pipeline, obtain the external environment impact correction factor through comprehensive analysis and processing, and send it to the data processing module.

[0054] The obtaining of the external environmental parameters of the cooling water pipeline and the comprehensive analysis and processing to obtain the external environmental impact correction factor specifically include: The external environmental parameters of the cooling water pipeline include the real-time external temperature, real-time external humidity and real-time external air pressure of each screening point.

[0055] The real-time external temperature refers to the temperature of the environment around the cooling water pipe. The external temperature will affect the heat exchange efficiency of the cooling system. If the external temperature is high, the heat dissipation effect may be reduced, causing the cooling water temperature to rise, affecting the cooling efficiency.

[0056] Real-time external humidity refers to the humidity level of the environment surrounding the cooling water pipes. Humidity affects the thermal conductivity of the air and the evaporation efficiency of the cooling tower. High humidity may cause the cooling effect of the cooling tower to decrease because wet air does not dissipate as much heat as dry air.

[0057] The real-time external air pressure refers to the air pressure of the environment around the cooling water pipeline. The change of air pressure will affect the boiling point of the cooling water. Under low air pressure, the boiling point of water decreases, which will affect the working efficiency of the cooling system.

[0058] The external temperature calibration value, external humidity calibration value and external air pressure calibration value are extracted from the database, and analyzed and processed with the external environmental parameters to obtain the external environmental impact correction factor, which specifically includes: ; in, is the correction factor for external environmental impact, For the Real-time external temperature at each screening point, For the Real-time external humidity at each screening point, For the Real-time external air pressure at each screening point, is the external temperature calibration value, is the external humidity calibration value, is the external air pressure calibration value, Number the screening point. , is the total number of screening points, and e is a natural constant.

[0059] It should be noted that the external environmental parameters of the cooling water pipeline include the real-time external temperature, real-time external humidity and real-time external air pressure of each screening point. There is a certain correlation between these parameters, which is mainly reflected in their joint action on the heat exchange process and cooling efficiency of the cooling system. Humidity affects the evaporative cooling effect of cooling. In a high temperature and high humidity environment, the evaporative efficiency of cooling will decrease because the air already contains more moisture, reducing the potential for cooling water evaporation. There is an inverse relationship between temperature and air pressure. Normally, the temperature increases and the air pressure decreases. Conversely, the temperature decreases and the air pressure increases. Changes in air pressure affect the boiling point of cooling water. Under low air pressure, the boiling point of water decreases, which may affect the cooling process. Under low air pressure, the amount of water vapor that the air can accommodate decreases, so the relative humidity will increase, and changes in air pressure may affect the measured value of humidity, so the influence of air pressure needs to be considered when analyzing humidity data.

[0060] The data processing module is used to obtain the cooling water flow required for the forging chamber based on the real-time temperature analysis of the forging chamber, and to obtain the transmission loss influence factor of the cooling water pipeline based on the real-time water flow parameters of the cooling water pipeline and the external environmental influencing factors. The cooling water flow required for the forging chamber and the transmission loss influence factor of the cooling water pipeline are comprehensively analyzed to obtain the total cooling water flow required for the forging chamber.

[0061] The method of obtaining the required cooling water flow rate of the forging chamber based on the real-time temperature analysis of the forging chamber, and obtaining the transmission loss influencing factor of the cooling water pipeline based on the real-time water flow parameters of the cooling water pipeline and the external environmental influencing factor, specifically includes: The real-time temperature of the forging chamber is compared with the set cooling temperature. If the real-time temperature of the forging chamber is less than or equal to the set cooling temperature, a minimum speed signal is sent to the closed-loop pumping unit to make the closed-loop pumping unit run at the minimum speed. The real-time temperature of the forging chamber is subtracted from the set cooling temperature to obtain the required heating temperature difference. The required heating temperature difference is mapped and matched with the heater power adjustment values ​​corresponding to each required heating temperature difference interval pre-stored in the database to obtain the power adjustment value of the heater in the forging chamber and adjust the heater power.

[0062] If the real-time temperature of the forging chamber is greater than the set cooling temperature, a differential process is performed to obtain the cooling temperature difference, and the cooling temperature difference is mapped and matched with the cooling water flow corresponding to each cooling temperature difference interval pre-stored in the database to obtain the required cooling water flow of the forging chamber.

[0063] The real-time water flow parameters of the cooling water pipeline are processed to obtain the real-time water flow characteristic value of the cooling water pipeline, and the transmission influence characteristic value of the cooling water pipeline is obtained by analyzing and processing in combination with the patency assessment value of the cooling water pipeline and the external environmental influencing factors. The transmission influence characteristic value of the cooling water pipeline is mapped and matched with the transmission loss influence factors corresponding to each transmission influence characteristic value interval preset in the database to obtain the transmission influence factor of the cooling water pipeline, and the transmission influence factor of the cooling water pipeline is used to correct the influence on the cooling water during the pipeline transmission process.

[0064] The processing obtains the real-time water flow characteristic value of the cooling water pipeline, and the specific processing conditions are: The expected water flow parameters of each point in the cooling water pipeline are extracted from the database, including the expected water temperature at each point, the expected flow rate at each point and the expected water pressure at each point. The expected water flow parameters at each point in the cooling water pipeline are the water flow parameters that are set during the development of the cooling water system after simulating water flow transmission to minimize the loss in the cooling water pipeline.

[0065] The real-time water flow parameters at each point of the cooling water pipeline are compared and analyzed with the expected water flow parameters to obtain the real-time water flow characteristic values ​​of the cooling water pipeline. The specific process is as follows: ; in, is the real-time water flow characteristic value of the cooling water pipeline, For cooling water pipe Real-time water temperature at each point, For cooling water pipe Real-time flow rate at each point, For cooling water pipe Real-time water pressure at each point, For cooling water pipe The expected water temperature at each point, For cooling water pipe The expected flow rate at each point, For cooling water pipe The expected water pressure at each point, is the water temperature weight factor, is the flow velocity weight factor, is the water pressure weight factor, Number the cooling water pipeline points. , is the total number of cooling water pipeline points. The softplus function is a built-in function in Python. , e is a natural constant.

[0066] It should be noted that the water temperature weight factor, flow velocity weight factor and water pressure weight factor all have a value range between 0 and 1 and satisfy The water temperature weight factor is an influence factor corresponding to the real-time water flow characteristic value of the cooling water pipeline preset in the database, which indicates the numerical value of the influence degree of water temperature on the real-time water flow characteristic value of the cooling water pipeline. The flow rate weight factor is an influence factor corresponding to the real-time water flow characteristic value of the cooling water pipeline preset in the database, which indicates the numerical value of the influence degree of flow rate on the real-time water flow characteristic value of the cooling water pipeline. The water pressure weight factor is an influence factor corresponding to the real-time water flow characteristic value of the cooling water pipeline preset in the database, which indicates the numerical value of the influence degree of water pressure on the real-time water flow characteristic value of the cooling water pipeline. When used, the water temperature weight factor, flow rate weight factor and water pressure weight factor can be directly obtained from the database, and the corresponding relationship is a pre-set mapping relationship. For example: the real-time water flow characteristic value of the cooling water pipeline forms a mapping set with the water temperature weight factor, the flow rate weight factor and the water pressure weight factor respectively, and the real-time water flow parameters are input into the mapping set to obtain the water temperature weight factor, the flow rate weight factor and the water pressure weight factor, wherein the mapping relationship is one-to-one correspondence.

[0067] It should be noted that the real-time water flow parameters in the cooling water pipeline include the real-time water temperature at each point, the real-time flow rate at each point, and the real-time water pressure at each point. There is a certain correlation between these parameters, and the water temperature directly affects the cooling efficiency. If the water temperature is too high, it may be necessary to increase the flow rate to improve the cooling efficiency, that is, to increase the heat exchange capacity by increasing the water flow rate. At a certain flow rate, the water temperature will change with the heat exchange process. An increase in flow rate may lead to faster temperature distribution, but it may also increase the friction loss of the pipeline. Changes in water temperature will affect the density of water, and then affect the water pressure. Generally, an increase in water temperature and a decrease in water density may cause a decrease in water pressure. An increase in water temperature may cause the cooling water circulation pump to provide a higher pressure to maintain the same flow rate. In fluid mechanics, the relationship between flow rate and water pressure can be described by the Darcy-Weisbach equation, which shows that the flow rate is proportional to the pressure difference at both ends of the pipeline. An increase in flow rate will lead to an increase in friction loss in the pipeline, which requires a higher water pressure to overcome these losses to maintain the required flow rate. Water temperature, flow rate and water pressure jointly determine the heat exchange efficiency of the cooling system. An increase in flow rate can increase the heat exchange rate, but it may also increase the water pressure requirement. An increase in flow rate will lead to an increase in pipe resistance, which usually requires a higher water pressure to maintain. These three parameters need to operate in a balanced state to ensure the stability and reliability of the cooling system.

[0068] In another embodiment of the invention, if the real-time water flow characteristic value of the cooling water pipeline is greater than or equal to the real-time water flow characteristic threshold, it is determined to be abnormal operation, an alarm is sent to the management terminal, and a minimum speed signal is sent to the closed-loop pumping unit at the same time, so that the closed-loop pumping unit operates at the minimum speed.
