Description

Technical Field

[0001] This application relates to the technical field of warm-up pump optimization, and in particular to a warm-up pump optimization method, system, terminal and storage medium. Background Technology

[0002] The warm-up pump optimization method refers to adjusting the operating parameters of the warm standby pump to achieve the best heat exchange efficiency during the preheating and standby process, with the aim of improving the stability of the warm standby pump's water intake pressure.

[0003] In related technologies, the warm-up pump optimization method typically involves passing high-temperature water through the shut-off valve and check valve on the main water intake line, and then flowing into the branch lines connected to the pressure pump, the pre-pump, and the bottom of the medium-pressure pipeline, which are equipped with multi-stage pressure-reducing orifice plates and shut-off valves. This allows for continuous heat exchange between the original ambient temperature medium in the warm-up standby pump and the high-temperature water in the main water intake line. Simultaneously, the original ambient temperature medium enters the deaerator through a small-flow pipeline, ultimately achieving stable warm-up of the pump.

[0004] Regarding the aforementioned technologies, high-temperature water flows into the branch lines connected to the pressure pump, the pre-pump, and the bottom of the medium-pressure pipeline, which are equipped with multi-stage pressure-reducing orifice plates and shut-off valves. However, if the high-temperature water contains impurities, such as scale or rust, it will clog the multi-stage pressure-reducing orifice plates, causing abnormal pressure increases or decreases, which in turn leads to unstable water intake pressure of the warm standby pump. There is still room for improvement. Summary of the Invention

[0005] To ensure the stability of the intake pressure of the warm standby pump, this application provides a warm pump optimization method, system, terminal, and storage medium.

[0006] Firstly, this application provides a method for optimizing a warm-up pump, employing the following technical solution: A method for optimizing a warm-up pump includes: Obtain system trigger signals; The system triggers a signal to control the opening of a preset water intake shut-off valve on the main water intake line and obtains a water source connection signal. The preset branch shut-off valve is opened based on the water source connection signal, and the branch connection signal is obtained. The pressure at the water intake point, the pressure in the warm pump chamber, and the pressure at the return end are obtained based on the branch connection signal.

If the conditions are not met, the pressure health index and the pressure in the warm pump chamber will be analyzed to determine the main circuit correction opening.

[0009] Optionally, the steps of analyzing the pressure health index and warm-up pump chamber pressure to determine the main circuit correction opening include: Determine whether the stress health index meets the preset standard blockage index range; If the conditions are met, a preset cleanup message will be output as a prompt. If it does not meet the requirements, obtain the outlet pressure of the warm pump; The outlet pressure and chamber pressure of the warm pump are analyzed to determine the main circuit correction opening.

[0010] Optionally, the steps of analyzing the warm pump outlet pressure and warm pump chamber pressure to determine the main circuit correction opening include: Calculate the difference between the warm pump outlet pressure and the warm pump chamber pressure to generate the warm pump reverse pressure differential; Determine whether the reverse pressure differential of the warm-up pump is less than the preset critical reverse pressure differential; If the value is less than the preset cleanup message, a prompt will be displayed. If it is not less than, the preset maximum shut-off valve opening is defined as the main road correction opening, and a preset reversal risk warning message is output.

[0011] Optionally, the steps of analyzing the pressure at the water intake point to determine the corrected branch opening include: Obtain historical water intake pressure at preset time points; Calculate the difference between the pressure at the water intake point and the historical water intake pressure to generate the pressure change value; Calculate the quotient of the pressure change value and the preset detection time difference to generate the pressure change rate; Determine whether the pressure change rate meets the preset standard change rate range; If the conditions are met, the preset standard shut-off valve opening is defined as the branch correction opening. If the condition is not met, the pressure change rate is analyzed to determine the corrected branch opening.

[0012] Optionally, the steps of analyzing the rate of pressure change to determine the corrected branch opening include: Calculate the difference between the absolute value of the pressure change rate and the preset fluctuation change rate to generate the fluctuation deviation value; Calculate the quotient of the fluctuation deviation value and the preset benchmark water intake pressure to generate the load variation coefficient; The pressure change rate, load change coefficient, preset opening gain coefficient, and preset reference shut-off valve opening are analyzed to determine the branch correction opening.

[0013] Secondly, this application provides a warm-up pump optimization system, which adopts the following technical solution: A warm-up pump optimization system includes: The acquisition module is used to acquire system trigger signals, water source connection signals, branch connection signals, water intake point pressure, warm pump chamber pressure, and return end pressure. A memory for storing a program for a warm-up pump optimization method as described in any of the preceding claims; The processor and the program in the memory can be loaded and executed by the processor to implement a warm pump optimization method as described in any of the above.

[0014] Thirdly, this application provides a smart terminal, which adopts the following technical solution: A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed as described in any of the preceding claims for a warm pump optimization method.

[0015] Fourthly, this application provides a computer storage medium capable of storing corresponding programs, which facilitates the achievement of ensuring the stability of the intake water pressure of the warm standby pump, and adopts the following technical solution: A computer-readable storage medium storing a computer program that can be loaded by a processor and executed any of the above-described warm pump optimization methods.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. By controlling the opening of the water intake shut-off valve on the main water intake line and then controlling the opening of the branch shut-off valve, the main line correction opening is determined after analyzing the water intake pressure, the warm pump chamber pressure, and the return end pressure. The branch line correction opening is determined after analyzing the water intake pressure. The opening of the water intake shut-off valve and the branch line shut-off valve are adjusted according to the main line correction opening and the branch line correction opening, respectively, thereby controlling the water intake main line to supply water to the warm standby pump. This allows for timely cleaning when the multi-stage pressure reducing orifice plate is blocked, thus ensuring the stability of the warm standby pump's water intake pressure. 2. A pressure health index is generated by calculating the quotient of the warm pump pressure drop coefficient and the standard pressure drop coefficient. When the pressure health index meets the range of the standard health index, the main pipeline reference opening is directly defined as the main pipeline correction opening. If it does not meet the range, the main pipeline correction opening is determined after analyzing the pressure health index and the warm pump cavity pressure. This allows for the determination of whether the multi-stage pressure reduction orifice plate is blocked based on the normality of the pressure, preventing unstable water intake pressure due to blockage of the multi-stage pressure reduction orifice plate, thereby improving the stability of the warm standby pump water intake pressure. 3. The heating pump reverse pressure differential is generated by calculating the difference between the heating pump outlet pressure and the heating pump chamber pressure. When the heating pump reverse pressure differential is less than the critical reverse pressure differential, a cleaning prompt message is directly output. If it is not less than the critical reverse pressure differential, the maximum shut-off valve opening is defined as the main line correction opening, and a reverse risk prompt message is output. This allows for timely cleaning prompts when the multi-stage pressure reducing orifice plate becomes blocked. When the multi-stage pressure reducing orifice plate becomes severely blocked, the water intake shut-off valve is opened to the maximum to attempt to flush out impurities, and a reverse risk prompt message is output to ensure the stability of the heating standby pump's water intake pressure.

[0024] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1 to 7 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0025] This application discloses a warm-up pump optimization method, specifically disclosing a main water intake pipeline, a water intake shut-off valve, branch shut-off valves, and a warm-up standby pump. A processing terminal is communicatively connected to the warm-up standby pump to achieve data interaction and control. After the processing terminal obtains a system trigger signal, it controls the opening of the water intake shut-off valve on the main water intake pipeline, and then controls the opening of the branch shut-off valve. By analyzing the water intake pressure, the warm-up pump cavity pressure, and the return end pressure, the main pipeline correction opening is determined, and the branch pipeline correction opening is determined by analyzing the water intake pressure. Based on the main pipeline correction opening and the branch pipeline correction opening, the opening of the water intake shut-off valve and the branch shut-off valve are adjusted respectively, thereby controlling the water intake pipeline to flow into the warm-up standby pump. This allows for timely cleaning when the multi-stage pressure-reducing orifice plate is blocked, ensuring the stability of the warm-up standby pump's water intake pressure.

[0026] Reference Figure 1 This application discloses a method for optimizing a warm-up pump, including the following steps: Step S100: Obtain the system trigger signal.

[0027] Among them, the system trigger signal refers to the system's trigger signal, which is triggered by the operator to activate the system's start switch, thereby sending the level signal representing the system trigger signal to the processing terminal, and then providing the opening conditions for the subsequent water intake shut-off valve and branch shut-off valve.

[0028] Step S101: Based on the system trigger signal, control the preset water intake shut-off valve on the preset water intake main line to open, and obtain the water source connection signal.

[0029] When the processing terminal receives the system trigger signal, it responds to the system trigger signal by controlling the water intake shut-off valve on the main water intake pipeline to open the water source channel so that water in the main water intake pipeline can flow into the warm standby pump.

[0030] The main water intake pipeline is a medium-pressure pipeline used for heat exchange with the warm standby pump. It is connected to the suction end of the warm standby pump. The water intake pipeline is equipped with a water intake shut-off valve and three branch lines. The three branch lines lead to the pre-pump, the pressure stage pump, and the bottom of the medium-pressure pipeline of the warm standby pump, respectively. The specific model is determined by the operator according to the actual situation.

[0031] A warm-up standby pump is a standby pump that is stopped but preheated and maintained at its operating temperature. It consists of a booster pump, a motor, a hydraulic coupler, and a pressure stage pump connected in series. The booster pump increases the inlet pressure of the pressure stage pump, preventing vaporization. The motor is the power source for the entire pump set, driving the booster pump and the pressure stage pump. The hydraulic coupler connects the motor and the pressure stage pump, controlling the water flow and pressure. The pressure stage pump is a multi-stage centrifugal pump used to further pressurize the water from the booster pump. The warm-up standby pump is connected in parallel with the operating pump set. The operating pump set refers to the pump that is working and undertaking the actual transportation task. Its composition is the same as the warm-up standby pump. The operating pump set is used to pump water from the low-pressure end to the high-pressure end and provide heat and pressure differential for the warm-up standby pump.

[0032] A water intake shut-off valve is a valve installed on the main water intake line to open or close the water source channel and to adjust the opening degree. The specific model is determined by the operator based on the actual situation.

[0033] The water supply start-up signal refers to the signal indicating that water has begun to flow after the water intake shut-off valve is opened. This signal is generated by the processing terminal sending a voltage level indicating the start-up signal after the water intake shut-off valve is opened. By confirming the water supply start-up signal, it is determined that the water intake shut-off valve has been fully opened, thus providing the necessary conditions for opening the branch shut-off valves subsequently.

[0034] Step S102: Based on the water source connection signal, control the preset branch shut-off valve to open and obtain the branch connection signal.

[0035] When the processing terminal receives the water source connection signal, it responds to the signal by controlling the branch shut-off valve to open the branch water source channel so that water in the main water intake pipeline can flow into the heating standby pump.

[0036] A branch stop valve is a valve installed on a branch pipeline connected to the main water intake pipeline. It is used to open or close the branch water source channel and adjust the opening degree. The specific model is determined by the operator according to the actual situation.

[0037] Branch pipelines refer to pipelines that connect to the main water intake pipeline at one end and to the warm standby pump and medium-pressure pipeline at the other end. Branch pipelines are equipped with branch shut-off valves and multi-stage pressure reducing orifice plates. The specific models are determined by the operators based on the actual situation.

[0038] Multi-stage pressure reducing orifice plates refer to multi-layered orifice plates used to further reduce the water pressure in the main water intake pipeline to a pressure suitable for injection into the warm standby pump chamber. The pressure difference before and after the multi-stage pressure reducing orifice plate is 3.8 MPa. The specific model is determined by the operator based on the actual situation.

[0039] The branch connection signal refers to the signal that water begins to flow after the branch shut-off valve is opened. This signal is obtained by the processing terminal sending a voltage level representing the branch connection signal after the branch shut-off valve is opened. By confirming the branch connection signal, it is determined that the branch shut-off valve has been fully opened, facilitating the subsequent determination of the correct branch opening degree.

[0040] Step S103: Obtain the water intake point pressure, warm pump chamber pressure, and return end pressure based on the branch connection signal.

[0041] The water intake point pressure refers to the water source pressure in the main water intake pipeline, which is read by the treatment terminal from the pressure transmitter installed on the main water intake pipeline. The water intake point pressure is strongly correlated with the total pressure difference of the heating pump. The higher the water intake point pressure, the higher the water source pressure in the water intake pipeline, and thus the higher the total pressure difference of the heating pump.

[0042] Warm-up pump chamber pressure refers to the pressure within the internal flow channels and pump casing of the standby pump, which is read from the pressure transmitter on the pump casing by the processing terminal. Warm-up pump chamber pressure is strongly correlated with warm-up pump pressure drop; a higher warm-up pump chamber pressure indicates a higher pressure on the pump casing wall of the standby pump, resulting in a greater warm-up pump pressure drop.

[0043] The return end pressure refers to the pressure at the final point where the warm standby pump water flow converges. It is read from the static pressure transmitter of the deaerator tank water level at the treatment terminal. The return end pressure represents the lower limit that the system pressure can reach.

[0044] A deaerator is a pressure vessel used for degassing, preheating, and water storage. It removes dissolved oxygen from the feed water and is connected to the main intake pipe of the warm standby pump. The specific model is determined by the operator based on the actual situation.

[0045] Step S104: Analyze the pressure at the water intake point, the pressure in the warm pump chamber, and the pressure at the end of the return flow to determine the correct opening of the main pipeline.

[0046] The main pipeline correction opening refers to the opening of the water intake shut-off valve after adjustment based on the blockage status of the multi-stage pressure-reducing orifice plate. This opening is obtained by analyzing the water intake pressure, warm-up pump chamber pressure, and return end pressure at the treatment terminal. Specific methods are detailed in [reference needed]. Figure 2 The steps involve determining the main pipeline correction opening to prevent uncontrolled pressure in the warm standby pump chamber due to blockage of the multi-stage pressure-reducing orifice plates, thereby ensuring the stability of the warm standby pump's intake pressure.

[0047] Step S105: Analyze the pressure at the water intake point to determine the corrected opening of the branch.

[0048] Among them, the branch line correction opening refers to the opening of the branch line shut-off valve after adjustment based on the pressure changes in the main water intake line. This is obtained by analyzing the pressure at the water intake point from the treatment terminal. The specific method is described in [reference needed]. Figure 6 The steps are as follows. By determining the branch correction opening, it is possible to effectively avoid the situation where the pressure of the main water intake pipeline rises or falls instantaneously due to the instantaneous change in the load of the operating pump group, which would lead to a decrease in heat exchange efficiency, thereby improving the stability of the water intake pressure of the warm standby pump.

[0049] Step S106: Adjust the opening of the water intake stop valve and the branch stop valve according to the main line correction opening and the branch line correction opening respectively, so as to control the water intake main line to flow water into the preset warm standby pump.

[0050] In this process, after determining the branch correction opening, the processing terminal adjusts the opening of the water intake shut-off valve and the branch shut-off valve according to the main line correction opening and the branch line correction opening, respectively, thereby controlling the main water intake line to supply water to the warm standby pump at a stable pressure, thus ensuring the effect of improving the stability of the warm standby pump's water intake pressure.

[0051] Reference Figure 2 The steps for analyzing the pressure at the water intake point, the pressure in the warm-up pump chamber, and the pressure at the return end to determine the correct opening of the main pipeline include: Step S200: Calculate the difference between the warm-up pump chamber pressure and the return end pressure to generate the warm-up pump pressure drop.

[0052] The warm-up pump pressure drop refers to the effective pressure drop from the warm standby pump to the return terminal, which is obtained by calculating the difference between the warm-up pump chamber pressure and the return terminal pressure at the processing terminal. When the return terminal pressure remains constant, the higher the warm-up pump chamber pressure, the higher the pressure the warm standby pump withstands, resulting in better heat exchange performance. This provides data support for subsequently determining the warm-up pump pressure drop coefficient.

[0053] Step S201: Calculate the pressure difference between the water intake point and the return end pressure to generate the total pressure difference of the warm-up pump.

[0054] The total pressure difference of the warm-up pump refers to the total pressure difference from the inlet of the warm-up standby pump to the end of the water source return flow. It is obtained by calculating the difference between the pressure at the water intake point and the pressure at the return flow end from the treatment terminal. By determining the total pressure difference of the warm-up pump, the maximum pressure difference that the entire warm-up standby pump circuit can be determined, thus providing data support for subsequently determining the pressure drop coefficient of the warm-up pump.

[0055] Step S202: Calculate the quotient of the warm-up pump pressure drop and the total warm-up pump pressure difference to generate the warm-up pump pressure drop coefficient.

[0056] The warm-up pump pressure drop coefficient is a value that measures the proportion of the effective pressure difference from the warm-up standby pump chamber to the return end to the total pressure difference. It is obtained by calculating the quotient of the warm-up pump pressure drop and the total warm-up pump pressure difference at the processing terminal. The smaller the warm-up pump pressure drop coefficient, the less effective the multi-stage pressure-reducing orifice plate is. In this case, the multi-stage pressure-reducing orifice plate may be blocked, providing data support for determining the main line correction opening later.

[0057] Step S203: Analyze the pressure in the warm-up pump chamber and the pressure drop coefficient of the warm-up pump to determine the main circuit correction opening.

[0058] After determining the warm-up pump pressure drop coefficient, the processing terminal analyzes the warm-up pump cavity pressure and the warm-up pump pressure drop coefficient to obtain the main circuit correction opening. The specific method is described in [reference needed]. Figure 3 The steps involve determining the main pipeline correction opening to prevent uncontrolled pressure in the warm standby pump chamber due to blockage of the multi-stage pressure-reducing orifice plates, thereby ensuring the stability of the warm standby pump's intake pressure.

[0059] Reference Figure 3 The steps for analyzing the warm-up pump chamber pressure and warm-up pump pressure drop coefficient to determine the main road correction opening include: Step S300: Calculate the quotient of the warm pump pressure drop coefficient and the preset standard pressure drop coefficient to generate a pressure health index.

[0060] The pressure health index measures the normality of pressure transmission efficiency and is obtained by calculating the quotient of the warm-up pump pressure drop coefficient and the standard pressure drop coefficient at the treatment terminal. A decrease in the pressure health index indicates blockage of the multi-stage orifice plate, leading to pressure loss in the warm-up standby pump chamber. Severe blockage poses a risk of high-pressure backflow causing impeller reversal. Therefore, the pressure health index provides a basis for determining whether the multi-stage pressure-reducing orifice plate is blocked, thereby improving the stability of the warm-up standby pump's intake pressure.

[0061] The standard pressure drop factor is a value that measures the proportion of the effective pressure difference from the warm standby pump chamber to the return end under normal conditions to the total pressure difference. It is set in advance by the operator. By determining the standard pressure drop factor, the pressure transmission efficiency when the multi-stage pressure reduction orifice plate is not blocked can be determined, providing data support for determining the pressure health index.

[0062] Step S301: Determine whether the stress health index meets the preset standard health index range.

[0063] The standard health index refers to the normal pressure transmission efficiency value when the multi-stage pressure reducing orifice plate is not blocked. The range of the standard health index is set in advance by the operator. By judging whether the pressure health index is within the standard health index range, it is determined whether the multi-stage pressure reducing orifice plate is blocked, thereby effectively avoiding the reduction of pressure transmission efficiency caused by the blockage of the multi-stage pressure reducing orifice plate, and thus effectively preventing the impeller from reversing.

[0064] Step S3011: If the conditions are met, the preset main road reference opening is defined as the main road corrected opening.

[0065] If the pressure health index is within the standard health index range, it indicates that the pressure transmission efficiency is normal. At this time, the multi-stage pressure reducing orifice plate is not blocked. Therefore, the treatment terminal directly defines the main line reference opening as the main line correction opening, thereby ensuring the effect of improving the stability of the hot standby pump water intake pressure.

[0066] The main line reference opening degree refers to the opening degree of the water intake shut-off valve when the multi-stage pressure reducing orifice plate is not blocked, which is set in advance by the operator. By determining the main line reference opening degree, the opening degree of the water intake shut-off valve when the multi-stage pressure reducing orifice plate is not blocked can be determined, thereby improving the stability of the water intake pressure of the warm standby pump.

[0067] Step S3012: If it does not meet the requirements, analyze the pressure health index and the warm pump chamber pressure to determine the main circuit correction opening.

[0068] If the pressure health index is outside the standard health index range, it indicates abnormal pressure transmission efficiency. This suggests blockage in the multi-stage pressure-reducing orifice plate. Therefore, the treatment terminal analyzes the pressure health index and the pressure in the warm-up pump chamber to determine the correct opening of the main circuit. The specific method is described in [reference needed]. Figure 4 This process involves adjusting the main pipeline opening in a timely manner when the multi-stage pressure-reducing orifice plate becomes clogged, thereby ensuring the stability of the hot standby pump's intake pressure.

[0069] The main path correction opening in this step is the same as the main path correction opening in step S3011. The difference is that the main path correction opening in this step is obtained by the processing terminal after analyzing the pressure health index and the pressure of the warm pump chamber.

[0070] Reference Figure 4 The steps for analyzing the pressure health index and the pressure in the warm pump chamber to determine the main circuit correction opening include: Step S400: Determine whether the stress health index meets the preset standard blockage index range.

[0071] The standard blockage index measures slight blockage in the multi-stage pressure-reducing orifice plate. The standard blockage index range is predetermined by the operator. By determining whether the pressure health index falls within the standard blockage index range, it is possible to ascertain whether the multi-stage pressure-reducing orifice plate is severely blocked, thus facilitating the subsequent determination of the main line correction opening.

[0072] Step S4001: If the condition is met, output the preset cleanup prompt message.

[0073] If the pressure health index is within the standard blockage index range, it indicates that the multi-stage pressure reducing orifice plate is slightly blocked, which will reduce the pressure reduction effect. At this time, the processing terminal directly outputs a cleaning prompt message to remind the operator to clean the multi-stage pressure reducing orifice plate when it is slightly blocked, thereby ensuring the stability of the water intake pressure of the warm standby pump.

[0074] The cleaning prompt message is a notification sent to the operator to clean the multi-stage pressure-reducing orifice plate. This message is stored in the processing terminal by the operator. By confirming the cleaning prompt message, the multi-stage pressure-reducing orifice plate can be cleaned promptly when blockage occurs, thus effectively preventing a decrease in pressure transmission efficiency.

[0075] Step S4002: If not, obtain the outlet pressure of the warm pump.

[0076] If the pressure health index is not within the range of the standard blockage index, it means that the scale or rust in the main water intake pipeline has seriously blocked the multi-stage pressure reduction orifice plate, and the warm standby pump has lost its ability to actively stabilize pressure. There is a risk of high pressure backflow causing the impeller to reverse. At this time, the treatment terminal obtains the outlet pressure of the warm pump in order to determine the main pipeline correction opening.

[0077] The warm-up pump outlet pressure refers to the pressure at the outlet of the warm-up standby pump, which is read from the pressure transmitter at the outlet of the warm-up standby pump by the processing terminal. By determining the warm-up pump outlet pressure, the pressure difference between the outside and inside of the warm-up standby pump can be determined, which helps to determine whether there is a risk of backflow or reverse flow.

[0078] Step S40021: Analyze the outlet pressure and chamber pressure of the warm pump to determine the main circuit correction opening.

[0079] After determining the heater pump outlet pressure, the processing terminal analyzes the heater pump outlet pressure and heater pump cavity pressure to obtain the main line correction opening. The specific method is described in [reference needed]. Figure 5 This process involves adjusting the main pipeline opening in a timely manner when severe blockage occurs in the multi-stage pressure reduction orifice plate, attempting to flush out impurities and thus ensuring the stability of the warm standby pump's intake pressure.

[0080] Reference Figure 5 The steps for analyzing the warm pump outlet pressure and warm pump chamber pressure to determine the main line correction opening include: Step S500: Calculate the difference between the warm pump outlet pressure and the warm pump chamber pressure to generate the warm pump reverse pressure differential.

[0081] The warm-up pump reversal pressure differential refers to the pressure difference between the inside and outside of the warm-up standby pump, which is obtained by calculating the difference between the warm-up pump outlet pressure and the warm-up pump chamber pressure from the processing terminal. By determining the warm-up pump reversal pressure differential, it is possible to determine whether the current pressure difference between the inside and outside of the warm-up standby pump will cause the warm-up standby pump impeller to reverse, so as to determine the main line correction opening in the subsequent process.

[0082] Step S501: Determine whether the reverse pressure difference of the warm-up pump is less than the preset critical reverse pressure difference.

[0083] The critical reversal pressure difference refers to the critical pressure difference that can cause the impeller of the warm standby pump to reverse, and it is set in advance by the operator. By judging whether the warm pump reversal pressure difference is less than the critical reversal pressure difference, it is determined whether the current internal and external pressure difference of the warm standby pump will cause the impeller to reverse, so as to determine the main circuit correction opening later.

[0084] Step S5011: If it is less than, output the preset cleanup prompt message.

[0085] If the pressure difference of the warm pump reversal is less than the critical pressure difference of the reversal, it means that the pressure difference between the inside and outside of the current warm standby pump will not cause the impeller to reverse, but it is still in a blocked state. At this time, the processing terminal directly outputs a cleaning prompt message to prompt the timely cleaning of the multi-stage pressure reduction orifice plate, thereby ensuring the effect of improving the stability of the water intake pressure of the warm standby pump.

[0086] The cleanup prompts in this step are the same as those in step S4001.

[0087] Step S5012: If it is not less than, then the preset maximum shut-off valve opening is defined as the main road correction opening, and the preset reversal risk warning information is output as a warning.

[0088] If the reverse pressure difference of the warm pump is not less than the critical reverse pressure difference, it indicates that the pressure difference between the inside and outside of the current warm standby pump is unbalanced, which can easily lead to water backflow and impeller reversal. At this time, the processing terminal defines the maximum shut-off valve opening as the main line correction opening and outputs a reverse risk warning message. Then, when there is a risk of reverse reversal, the opening of the water intake shut-off valve is adjusted to the maximum to try to flush out impurities.

[0089] The maximum shut-off valve opening refers to the maximum opening degree of the water intake shut-off valve, which is set in advance by the operator. By determining the maximum shut-off valve opening, when there is a risk of reverse rotation of the warm standby pump, an attempt can be made to flush away impurities with the maximum shut-off valve opening, thereby improving the stability of the warm standby pump's water intake pressure.

[0090] Reversal risk warning information refers to the information that alerts operators when there is a risk of reversal in the warm standby pump. This information is stored by the operator on the processing terminal. By identifying reversal risk warning information, operators can be promptly reminded to check the warm standby pump when a reversal risk is detected, thereby improving the stability of the warm standby pump's water intake pressure.

[0091] Reference Figure 6 The steps for analyzing the pressure at the water intake point to determine the corrected opening of the branch include: Step S600: Obtain the historical water intake pressure at a preset time point.

[0092] Historical water intake pressure refers to the historical water source pressure in the main water intake pipeline, which is read by the processing terminal from the pressure transmitter installed on the main water intake pipeline. By determining the historical water intake pressure, the difference between the current water intake pressure and the historical water intake pressure can be determined, thereby determining the change in water intake pressure and providing data support for subsequent determination of pressure change values.

[0093] A time point refers to a point in time that is some distance from the current moment, and is set in advance by the operator. By determining the time point, the historical water intake pressure at that time point can be determined, so as to facilitate the subsequent determination of pressure change values.

[0094] Step S601: Calculate the difference between the pressure at the water intake point and the historical water intake pressure to generate the pressure change value.

[0095] The pressure change value refers to the change in pressure at the water intake point over a period of time. It is obtained by calculating the difference between the water intake point pressure and the historical water intake pressure from the treatment terminal. By determining the pressure change value, the change in pressure at the water intake point over a period of time can be determined, providing data support for subsequently determining the pressure change rate.

[0096] Step S602: Calculate the quotient of the pressure change value and the preset detection time difference to generate the pressure change rate.

[0097] The pressure change rate measures the magnitude of pressure change at the water intake point over a period of time. It is calculated by the treatment terminal as the quotient of the pressure change value and the detection time difference. With a constant detection time difference, a larger pressure change value indicates a greater degree of pressure change over a period of time, thus resulting in a larger pressure change rate. This facilitates subsequent determination of whether the load on the operating pump unit has changed rapidly.

[0098] The detection time difference refers to the time difference between detecting pressure changes at the water intake point, which is preset by the operator. By determining the detection time difference, the magnitude of pressure change within this time difference can be determined, thus providing data support for determining the pressure change rate.

[0099] Step S603: Determine whether the pressure change rate meets the preset standard change rate range.

[0100] The standard rate of change refers to the value that measures the magnitude of pressure change at the water intake point under stable load, and the range of the standard rate of change refers to the range within which the pressure changes. By determining whether the pressure rate of change is within the range of the standard rate of change, it can be determined whether the load of the operating pump set has changed rapidly. When the load of the operating pump set changes instantaneously, the pressure of the main water intake pipeline will also fluctuate. Therefore, the change in the pressure rate of change can reflect the load change of the operating pump set.

[0101] Step S6031: If the condition is met, the preset standard shut-off valve opening is defined as the branch correction opening.

[0102] If the pressure change rate is within the standard change rate range, it indicates that the load of the operating pump set is stable and no rapid load change has occurred. At this time, the treatment terminal directly defines the standard shut-off valve opening as the branch correction opening to ensure the effect of improving the stability of the hot standby pump water intake pressure.

[0103] The standard shut-off valve opening refers to the opening degree of the branch shut-off valve when the operating pump set load is stable, which is set in advance by the operator. By determining the branch shut-off valve, the opening degree of the branch shut-off valve is adjusted to the standard shut-off valve opening degree when the operating pump set load is stable, thereby improving the stability of the water intake pressure of the warm standby pump.

[0104] Step S6032: If it does not meet the requirements, analyze the pressure change rate to determine the branch correction opening.

[0105] If the pressure change rate is outside the standard range, it indicates a rapid change in the load of the operating pump unit, which will also cause a rapid change in the pressure of the main intake pipe. A sudden increase in pressure can lead to a surge in flow in the warm standby pump's branch, potentially causing impeller reversal; a sudden decrease in pressure can result in insufficient flow in the warm standby pump, reducing heat transfer efficiency. Therefore, the processing terminal analyzes the pressure change rate to determine the corrected branch opening. Specific methods are detailed in [reference needed]. Figure 7 The steps.

[0106] The branch correction opening in this step is the same as the branch correction opening in step S6031. The difference is that the branch correction opening in this step is obtained by analyzing the pressure change rate at the processing terminal.

[0107] Reference Figure 7 The steps for analyzing the rate of pressure change to determine the corrected branch opening include: Step S700: Calculate the difference between the absolute value of the pressure change rate and the preset fluctuation change rate to generate the fluctuation deviation value.

[0108] The fluctuation deviation value refers to the value that measures the amplitude of the pressure change rate fluctuation. It is obtained by calculating the difference between the absolute value of the pressure change rate and the fluctuation rate of the pressure change rate from the processing terminal. By determining the fluctuation deviation value, the amplitude of the pressure change rate fluctuation can be determined. The larger the fluctuation deviation value, the greater the degree of load change of the operating pump unit, providing data support for the subsequent determination of the load change coefficient.

[0109] The fluctuation rate of change is a critical value used to measure the magnitude of pressure changes when there is a risk of reversal; it is pre-set by the operator. By determining the fluctuation rate of change, the fluctuation range of the pressure change rate can be determined, which facilitates the subsequent determination of the load change coefficient.

[0110] Step S701: Calculate the quotient of the fluctuation deviation value and the preset benchmark water intake pressure to generate the load change coefficient.

[0111] The load variation coefficient is a value that measures the degree of load change of the operating pump set. It is obtained by calculating the fluctuation deviation value and the reference water intake pressure from the treatment terminal. Under the condition that the reference water intake pressure remains unchanged, the larger the fluctuation deviation value, the faster the load of the operating pump set changes, thus providing data support for subsequent determination of the branch correction opening.

[0112] The reference water intake pressure refers to the pressure of the main water intake pipeline when the load is stable, which is set in advance by the operator. By determining the reference water intake pressure, the degree of load variation of the operating pump set can be determined, thereby providing data support for determining the load variation coefficient.

[0113] Step S702: Analyze the pressure change rate, load change coefficient, preset opening gain coefficient, and preset reference shut-off valve opening to determine the branch correction opening.

[0114] After determining the load variation coefficient, the processing terminal analyzes the pressure change rate, load variation coefficient, opening gain coefficient, and reference shut-off valve opening to obtain the branch correction opening, which can be expressed as follows: ,in To adjust the opening of the branch road, As the reference shut-off valve opening, The rate of change of pressure, This is the opening gain coefficient. The load variation coefficient, The sign function is as follows: When the rate of pressure change is positive, it indicates that the pressure is increasing, and the sign function is positive, thus reducing the opening of the branch shut-off valve; when the rate of pressure change is negative, the sign function is negative, thus increasing the opening of the branch shut-off valve, thereby ensuring the stability of the water intake pressure of the warm standby pump.

[0115] The opening gain coefficient is a value that measures the proportion of pressure difference converted into the opening degree of the branch shut-off valve, and is set in advance by the operator. By determining the opening gain coefficient, the opening degree of the branch shut-off valve can be adjusted according to the magnitude of pressure changes, thereby accurately responding to changes in the pressure at the water intake point caused by load changes in the operating pump set, and improving the stability of the water intake pressure of the standby pump.

[0116] The reference shut-off valve opening degree refers to the opening degree of the branch shut-off valve when the operating pump set load is stable, which is set in advance by the operator. By determining the reference shut-off valve opening degree, the opening degree of the branch shut-off valve can be adjusted based on the reference shut-off valve opening degree when the operating pump set load changes rapidly, thereby ensuring and improving the stability of the water intake pressure of the warm standby pump.
