[0002] Energy-saving pump is a commonly used conveying device, and also an energy-consuming equipment. Developing variable speed of energy-saving pump to achieve flow regulation and energy saving of energy-saving pump is an urgent problem to be solved in modern technology, and variable frequency speed regulation technology has been widely developed. Although the traditional energy-saving pump relies on the variable frequency of the inverter to adjust the speed, the power setting value of the inverter is given on-site by the operator. Now through software design, the regulator can achieve a strong control and regulation function. For example, when the load changes, the regulator adjusts the operating state of the pump according to the change of load to reduce the energy consumption of the pump. However, this regulation method has a certain hysteresis, which makes the pump residual pressure larger for a period of time, increasing energy consumption.

[0054] See also Figure 1 As shown, it is a flow chart of the energy-saving pump control system of this embodiment;

[0055] This embodiment provides an energy-saving pump control system, including:

[0056] A data acquisition module for detecting the real-time water flow in a delivery pipeline connected to a pump body, the pump body being arranged at a preset position downhole to pump water at a preset operating power;

[0057] A drawing module, connected to the data acquisition module, for drawing a flow change curve according to the real-time water flow within a preset time period;

[0058] A determination module, connected to the drawing module, for determining a number of abnormal pumping fluctuation flows according to the flow change curve;

[0059] A determination module, which is connected to the determination module and is used to determine the water supply stability of the underground water source according to all the abnormal pumping fluctuation flow rates, and to form a stable determination result and an unstable determination result;

[0060] An adjustment module is connected to the determination module and the pump body, respectively, and is used to adjust the preset operating power or issue an alarm of too low water supply according to the stable determination result and the real-time water flow rate, or to adjust the preset position or issue an alarm of pump body damage according to the unstable determination result.

[0061] The preset position is the position where the pump body is placed and installed underground. It depends on the height of the underground water level, the geological structure of the water source, the pipeline layout, and the type and capacity of the pump body. It is usually set at a distance of about 5 meters to 15 meters above the bottom of the well, and in this embodiment, it is set at a distance of about 10 meters above the bottom of the well. It can ensure sufficient water flow and prevent the pump body from being too close to the bottom of the well, thereby reducing the risk of mud and sand entering the pump body and ensuring the operation stability and service life of the pump body.

[0062] The preset operating power refers to the default setting power of the pump body under normal working conditions, which determines the power consumption and pumping efficiency of the pump body each time it operates, and depends on the design specifications of the pump body, the underground water supply capacity, the pipeline resistance, and the required water flow and pressure requirements. Normally, the power of the pump body is set between 70% and 90% of its rated power. In this embodiment, it is set to 80% of its rated power, which can reduce energy consumption while ensuring sufficient water supply.

[0063] The preset duration is the working time of the pump body in continuous operation or one cycle. This time is used to control when the pump body starts and stops to meet the water demand. It depends on the fluctuation of water supply demand, the water storage capacity of the system, the peak water use period and the speed of water supply. It is usually set between 25 minutes and 50 minutes. In this embodiment, it is set to 30 minutes to ensure that each pumping can meet the regular water demand. It can effectively avoid frequent starting and stopping of the pump body, reduce equipment wear and improve energy efficiency.

[0064] The data acquisition module detects the water flow in the delivery pipeline in real time, and the pump body pumps water underground according to the preset operating power. The drawing module converts the real-time water flow into a flow change curve, and identifies abnormal pumping fluctuations through the determination module. The judgment module evaluates the water supply stability of the underground water source based on these abnormal fluctuations in flow, and generates a stable or unstable judgment result. The adjustment module adjusts the operating power of the pump body according to the judgment result, or issues an alarm when the water flow is too low, or adjusts the pump body position or prompts equipment damage when the water supply is unstable.

[0065] Through intelligent water flow monitoring and abnormal fluctuation analysis, dynamic adjustment of the pump operating power is achieved, which significantly improves energy utilization efficiency and reduces unnecessary power consumption. The system can automatically determine the stability of underground water supply and promptly issue an alarm when the water supply is insufficient to ensure the continuity of water demand. Through real-time adjustment of the pump position and recording of multiple abnormal situations, it can also effectively prevent equipment damage and extend its service life, reducing downtime and maintenance costs. In addition, the system's automated adjustment and alarm functions make the entire pumping process more stable and reliable, improving the operational safety and economy of the entire system. It is suitable for complex underground pumping scenarios and effectively solves the problem of high energy consumption caused by low matching between pump power and water flow.

[0066] Specifically, the determination module includes:

[0067] an average value calculation unit, used to calculate the average value according to the flow change curve to obtain the flow average value;

[0068] An interval setting unit is connected to the calculation unit and is used to set a normal pumping fluctuation flow interval according to the flow average value. The upper limit of the normal pumping fluctuation flow interval is the flow average value plus a preset allowable fluctuation value, and the lower limit is the flow average value minus the preset allowable fluctuation value.

[0069] The preset allowable fluctuation value is a value set according to the fluctuation of normal water flow during the operation of the pump body. It is used to define the acceptable upper and lower fluctuation range of flow during the pumping process. It depends on the specifications and performance of the pump body, the stability of the water source and the actual operating environment. It is usually set between 5% and 15% of the average flow rate. In this embodiment, it is set to 10%, which can ensure that it can adapt to small-scale flow fluctuations without significantly affecting the pumping efficiency of the pump body.

[0070] The flow rate change curve provided by the data acquisition module is analyzed by the average value calculation unit, and the average flow rate within a certain period of time is first calculated. Then, the interval setting unit sets a reasonable normal pumping fluctuation flow interval based on the calculated flow rate average value, so as to judge the flow fluctuation later. These data provide the basis for the subsequent abnormal flow detection and water supply stability judgment of the system.

[0071] By calculating the average flow rate and setting the normal fluctuation range, the system can quickly identify abnormal flow fluctuations and avoid incorrect judgments due to occasional slight fluctuations.

[0072] Please continue reading Figure 2 As shown, it is a determination logic diagram of the fluctuation determination unit of this embodiment for determining abnormal pumping fluctuation flow;

[0073] Specifically, the determination module also includes:

[0074] A fluctuation determination unit is connected to the calculation unit and the setting unit respectively, and is used to determine that the real-time water flow is an abnormal pumping fluctuation flow when the flow average value is not within the normal pumping fluctuation flow interval.

[0075] By monitoring the water flow of the pump in real time, the current water flow is compared with the set normal pumping fluctuation flow range. If the real-time water flow exceeds this range, it is determined to be abnormal pumping fluctuation flow. The fluctuation determination unit will mark and count these out-of-range flow fluctuations as the basis for subsequent stability analysis.

[0076] Through the fluctuation determination unit, the system can accurately identify abnormal fluctuations in the pumping process, effectively eliminate flow fluctuations within the normal range, and reduce misjudgments.

[0077] Please continue reading Figure 3 As shown, it is a determination logic diagram of the stability determination result formed by the stability determination unit of this embodiment;

[0078] Specifically, the determination module includes:

[0079] A proportion calculation unit, used for calculating the proportion of all the abnormal pumping fluctuation flows on the flow change curve;

[0080] A stability determination unit is connected to the proportion calculation unit and is used to determine the stability of the water supply of the underground water source when the proportion is less than or equal to a preset standard proportion, thereby forming a stability determination result.

[0081] The preset standard ratio is a benchmark value set by the system when determining the stability of underground water supply, which is used to measure the allowable proportion of abnormal pumping fluctuation flow in the overall flow change. It is usually set between 5% and 15%, and is set to 10% in this embodiment. Through the preset standard ratio, the system can effectively identify the critical point of water supply and reduce false alarms.

[0082] During the flow change process, the proportion calculation unit continuously monitors the abnormal pumping fluctuation flow and calculates its proportion in the overall flow fluctuation in real time. The stability judgment unit determines whether the water supply of the underground water source is stable based on the preset standard proportion. If the proportion exceeds the standard proportion, the system will be judged as unstable, otherwise it will be judged as stable.

[0083] Through the judgment module, the system can effectively evaluate the water supply stability of the underground water source, promptly detect the unstable water supply situation, and ensure the normal use of the water source and the safe operation of the pump body.

[0084] Specifically, the adjustment module includes:

[0085] A first starting unit, used to start the flow comparison unit according to the stability determination result;

[0086] The flow comparison unit is connected to the comparison start unit and is used to compare the flow average value within the preset standard flow range with the standard flow value corresponding to each operating power in the preset standard power flow comparison diagram to form a flow comparison result;

[0087] A power adjustment unit is connected to the flow comparison unit and is used to adjust the preset operating power according to the flow comparison result.

[0088] The preset standard power flow comparison chart is a chart used to show the flow range of the pump under different operating powers, depending on the design characteristics of the pump, the fluid characteristics and the specific application scenarios. In this embodiment, the preset standard power flow comparison chart is set to multiple operating powers corresponding to multiple flow ranges, for example, 5 kilowatts correspond to 25 cubic meters per hour to 35 cubic meters per hour, 10 kilowatts correspond to 55 cubic meters per hour to 65 cubic meters per hour, and so on. Through such a setting, the flow range corresponding to each power can be clearly seen, which is convenient for real-time monitoring of the water supply status, and timely discovery and resolution of problems such as insufficient water supply. The standard flow values ​​in the figure refer to the ideal flow values ​​that the pump can achieve under a specific operating power. These standard flow values ​​are usually based on the performance curve of the pump and are set in combination with the actual application scenario and fluid characteristics. In this figure, each operating power will correspond to a standard flow value, which can represent the flow under optimal working conditions.

[0089] When the water supply stability judgment is completed, the first start unit activates the flow comparison unit, which generates a flow comparison result by comparing the average flow value with the preset standard flow value. Subsequently, the power adjustment unit adjusts the operating power of the pump according to this result to ensure the performance of the pump and the stability of the water flow.

[0090] Through the adjustment module, the system can dynamically adjust the operating power of the pump according to the real-time flow changes, improve energy efficiency, and reduce unnecessary energy consumption. At the same time, ensuring that the working state of the pump matches the stability of the water flow helps to extend the service life of the pump body and reduce maintenance costs, thereby improving the operating efficiency of the overall system.

[0091] Please continue reading Figure 4 As shown, it is a decision logic diagram of the first power adjustment subunit adjusting the preset operating power in this embodiment;

[0092] Specifically, the power adjustment unit includes:

[0093] A first power adjustment subunit, configured to reduce the preset operating power according to a preset adjustment coefficient when the flow comparison result shows that the average flow value is less than the standard flow value;

[0094] The adjusted preset operating power is equal to the difference between 1 and the preset adjustment coefficient multiplied by the preset operating power.

[0095] a deviation calculation subunit, connected to the first power adjustment subunit, for calculating a relative deviation between the preset operating power and the temporary operating power to form a power deviation, and for calculating a relative deviation between the real-time water flow rate before and after adjusting the preset operating power to form a flow deviation;

[0096] The second power adjustment subunit is connected to the deviation calculation subunit and is used to adjust the preset operating power according to the flow comparison result, the flow deviation and the power deviation, that is:

[0097] When the flow deviation is greater than the power deviation, increasing the preset operating power according to the flow deviation;

[0098] When the flow deviation is smaller than the power deviation, the preset operating power is reduced according to the flow deviation.

[0099] The preset adjustment coefficient is a parameter used to adjust the preset operating power of the pump during the flow comparison process. It is usually set between 0.1 and 0.3. In this embodiment, the preset adjustment coefficient is set to 0.2, which can effectively reduce energy consumption and optimize the operating efficiency of the pump body while ensuring stable water supply.

[0100] When the flow comparison result shows that the average flow value is less than the standard flow value, the first power adjustment subunit reduces the preset operating power according to the preset adjustment coefficient. Subsequently, the deviation calculation subunit calculates the relative deviation between the preset operating power and the temporary operating power to form a power deviation, and also calculates the relative deviation of the real-time water flow before and after the adjustment to form a flow deviation. Finally, the second power adjustment subunit further adjusts the preset operating power according to the flow comparison result, flow deviation and power deviation to ensure the optimized performance of the pump under different operating conditions.

[0101] Real-time calculation of power and flow deviations can help the system identify potential problems in a timely manner and make appropriate adjustments to ensure the stability and safety of water supply.

[0102] Specifically, the power adjustment unit also includes:

[0103] The water supply alarm subunit is used to issue an alarm of low water supply based on the comparison result of the minimum value of the preset standard flow range and the average flow rate, that is, when the minimum value is greater than the average flow rate, it is determined that the water level is insufficient and an alarm of low water supply is issued.

[0104] The water supply alarm subunit compares the minimum value of the preset standard flow range with the average flow rate. When the average flow rate is lower than the minimum value of the standard flow range, the system determines that the water supply is insufficient and triggers the low water supply alarm. This process ensures that the system can monitor the water supply status in time to respond to potential water supply shortages.

[0105] By comparing the average flow rate with the minimum value of the standard flow range, the water supply alarm subunit can quickly identify insufficient water supply, thereby effectively preventing equipment damage or abnormal operation caused by insufficient water level.

[0106] Specifically, the stability determination unit is also used to determine that the water supply of the underground water source is unstable when the proportion is greater than a preset standard proportion, thereby forming an unstable determination result.

[0107] The preset standard ratio is a reference value for judging the stability of water supply, which is usually set based on the system's operating requirements and historical data analysis. It indicates the maximum allowable proportion of abnormal pumping fluctuation flow in the overall flow change under normal circumstances. It depends on the analysis of the system's historical operating data, including fluctuations during normal operation, equipment performance, and the stability of water supply, and is usually set between 5% and 15%. This embodiment is set to 10% to ensure that the system can quickly determine whether the water supply is stable.

[0108] By calculating the proportion of all abnormal pumping fluctuation flows on the flow change curve and comparing it with the preset standard proportion, when the calculated proportion exceeds the preset standard proportion, the system determines that the water supply of the underground water source is unstable and forms a corresponding unstable judgment result. This process ensures real-time monitoring of the water supply status, enabling the system to respond quickly to potential water supply problems.

[0109] The real-time monitoring mechanism improves the safety and reliability of the water supply system and provides data support for subsequent water source management. The flexibility of the preset standard ratio also enables the system to be adjusted according to specific needs to ensure the continuity and stability of water supply under different working conditions.

[0110] Specifically, the adjustment module also includes:

[0111] A second starting unit, used for starting the position adjustment unit according to the unstable determination result;

[0112] The position adjustment unit is connected to the second starting unit and is used to adjust the preset position according to the unstable judgment result, the proportion, the preset standard proportion and the preset position coefficient, calculate the relative deviation by the proportion and the preset standard proportion to form a proportion deviation, calculate the product of the proportion deviation and the preset position coefficient, calculate the sum of the product and 1 to obtain the position adjustment factor, calculate the product of the position adjustment factor and the preset position, and obtain the adjusted preset position.

[0113] When the system detects that the water supply is unstable, the position adjustment unit receives relevant data, including the unstable judgment result, the actual proportion, the preset standard proportion and the preset position coefficient. Through comprehensive analysis of these data, the position adjustment unit calculates a new preset position to ensure that the pump body operates in the appropriate position, thereby improving the stability and reliability of the water supply.

[0114] By introducing the position adjustment unit, the system can flexibly respond to unstable water supply situations, thereby effectively reducing water supply problems caused by improper position. This real-time dynamic adjustment mechanism improves the adaptability and operating efficiency of the system, allowing the pump body to work in the optimal position to ensure a stable supply of water.

[0115] Specifically, the position adjustment unit includes:

[0116] A recording subunit, used for recording the real-time number of times the preset position is adjusted;

[0117] The damage alarm subunit is connected to the recording unit and is used to issue an alarm of pump body damage when the real-time number is equal to the preset safety number.

[0118] The preset safety times refers to the maximum number of times the system allows the pump body to be adjusted during operation to ensure safe and stable operation of the equipment. In the actual operation of the pump body, each position adjustment will cause a certain amount of wear or load on the equipment. Therefore, the setting of the preset safety times depends on factors such as the durability of the equipment, the complexity of the operating environment, and the maintenance cycle of the pump body. It is usually set between 3 and 6 times, and is set to 5 times in this embodiment, which can ensure that the system issues a warning before the equipment is over-adjusted, thereby avoiding equipment failure caused by excessive wear.

[0119] When the number of adjustments exceeds the preset safety number, the damage alarm subunit will connect with the recording subunit and issue an alarm based on the comparison result between the real-time number and the preset safety number, reminding the user that the pump body may be at risk of damage. This mechanism ensures effective monitoring of the operating status of the pump body and timely warning of potential equipment failures.

[0120] By recording the number of adjustments in real time, abnormal situations can be discovered in time and alarms can be issued to prevent damage to the pump body caused by frequent adjustments.
